When the positioning member 22 is in the dismounting mode, the matching portion 222 enters the dismounting section 113 from the positioning section 112, and the matching portion 222 moves along the assembly and disassembly track 11 to the end of the disassembly section 113 and then leaves the assembly and disassembly track, so that the positioning member 22 leaves the assembly and disassembly section. Remove track 11. When the assembly and disassembly bracket 1 and the positioning assembly 2 of the disassembly mechanism are disassembled, a certain force is applied to the assembly and disassembly bracket 1 to overcome the elastic force of the elastic member 23, so that the matching portion 222 of the positioning member 22 leaves the installation section 111 and enters the disassembly section 113 . The assembly and disassembly bracket 1 can move relative to the positioning member 22 along the disassembly section 113 until the positioning member 22 leaves the assembly and disassembly track 11 to realize the disassembly of the assembly and disassembly support 1 and the positioning assembly 2 .

The beginning of the positioning section 112 is the connection end between the positioning section 112 and the installation section 111, the end of the positioning section 112 is the connection end between the positioning section 112 and the dismounting section 113; the end of the installation section 111 is the connection end between the installation section 111 and the positioning section 112 ; The beginning of the disassembly section 113 is the connection end between the disassembly section 113 and the positioning section 112 . The start of the positioning section 112 is lower than the end of the installation section 111 along the moving direction of the positioning member 22 in the assembly and disassembly track 11 , and the start of the positioning section 112 is located below the end of the installation section 111 . The end of the positioning section 112 is higher than the beginning of the dismounting section 113 , which means that the end of the positioning section 112 is above the starting end of the dismounting section 113 along the moving direction of the positioning member 22 in the mounting and dismounting track 11 . The disassembly section 113 extending away from the positioning section 112 means that the disassembly section 113 extends from the beginning to the end along a direction away from the positioning section 112 , and the end of the disassembly section 113 is located below the positioning section 112 . The terms "upper" and "lower" in the present disclosure only represent the relative positional relationship between the components of the easy-to-detach mechanism, and this relative positional relationship will not change when the easy-to-detach mechanism is displaced, overturned or turned upside down.

Generally, the connection between the installation section 111 , the positioning section 112 and the disassembly section 113 may be a smooth transition connection. During specific implementation, the positioning section 112 can be located between the beginning and the end of the installation section 111, that is, the beginning of the positioning section 112 is lower than the end of the installation section 111, and the lowest point of the positioning section 112 is higher than the beginning of the installation section 111; The positioning section 112 can be located between the beginning and the end of the disassembly section 113 , that is, the end of the positioning section 112 is higher than the beginning of the disassembly section 113 , and the lowest point of the positioning section 112 is higher than the end of the disassembly section 113 .

Since the beginning of the positioning section 112 is lower than the end of the installation section 111, the assembly and disassembly support 1 can be relatively opposite under the elastic force of the elastic member 23. As the positioning member 22 moves along the extending direction of the assembly and disassembly track 11 , the matching portion 222 automatically enters the positioning section 112 from the installation section 111 . The matching portion 222 entering the positioning section 112 can cooperate with the positioning section 112 , so that the positioning member 22 is positioned in the assembly and disassembly track 11 . Here, the elastic member 23 continuously provides the elastic force towards the mounting and dismounting bracket 1 to the mounting and disassembling bracket 1, and the starting end of the positioning section 112 is located below the end of the mounting section 111, so that the matching part 222 can only be positioned from the mounting section 111. The end enters the positioning section 112 , but the matching portion 222 cannot enter the installation section 111 from the beginning of the positioning section 112 . That is, when the assembly and disassembly bracket 1 moves relative to the positioning member 22 until the matching portion 222 is located at the end of the installation section 111 , the assembly and disassembly bracket 1 can only move under the action of the elastic force until the matching portion 222 automatically enters the positioning section 112 .

Since the end of the positioning section 112 is higher than the beginning of the disassembly section 113, the assembly and disassembly support 1 can be moved along the assembly and disassembly bracket 1 with respect to the positioning piece 22 under the action of the elastic force of the elastic piece 23. The extension direction of the dismounting track 11 moves, so that the mounting and dismounting support 1 leaves the mounting and dismounting track 11 automatically. Here, the elastic member 23 continuously provides the elastic force toward the assembly and disassembly bracket 1 towards the assembly and disassembly bracket 1, and the end of the positioning section 112 is located above the beginning of the disassembly section 113, so that the matching portion 222 can only move along the disassembly section 113 The extending direction of the moving part 222 cannot enter the positioning section 112 from the beginning of the dismantling section 113 . That is, when the assembly and disassembly bracket 1 moves relative to the positioning member 22 until the matching portion 222 is located at the beginning of the disassembly section 113 , the assembly and disassembly bracket 1 can only move under the action of the elastic force until the cooperation portion 222 automatically leaves the disassembly section 113 .

The timing matching part 222 can provide the force applied to the assembly and disassembly bracket 1 in the direction opposite to that of the user, and the user can stop applying force to the assembly and disassembly bracket 1 after sensing the reverse force and/or hearing the rattling sound . Since the end of the positioning section 112 is higher than the beginning of the dismounting section 113, the mounting and dismounting bracket 1 can move relative to the positioning element 22 along the extending direction of the mounting and dismounting track 11 under the action of the elastic force of the elastic member 23, so that the mounting and dismounting bracket 1 automatically The self-positioning section 112 enters the dismounting section 113 and moves along the dismounting section 113 until leaving the assembly and disassembly track 11 . Here, the elastic member 23 continuously provides the elastic force toward the assembly and disassembly bracket 1 towards the assembly and disassembly bracket 1, and the end of the positioning section 112 is located above the beginning of the disassembly section 113, so that the matching portion 222 can only move along the disassembly section 113 The extending direction of the moving part 222 cannot enter the positioning section 112 from the beginning of the dismantling section 113 . That is, when the assembly and disassembly bracket 1 moves relative to the positioning member 22 until the matching portion 222 is located at the beginning of the disassembly section 113 , the assembly and disassembly bracket 1 can only automatically leave the disassembly section 113 under the action of elastic force.
