When the fixed part 100 is rotated to a locked position other than the first position, that is, when the user dials the character wheel to make the number different from the unlocking number, a part of the moving part 300 enters the limit part 711, and the second end part 220 restricts the moving part. 300 moves towards the fixture 100 . When the fixed part 100 is rotated to the first position, that is, the unlocked position when the user dials the character wheel to make the number the same as the unlocking number, the second end 220 releases the restriction on the movement of the moving part 300 towards the fixed part 100, and the moving part 300 Can leave the limiting part 711.

More specifically, in the embodiment shown in FIGS. 3A to 3C , the rotating wheel 110 includes a rotating member 111 and a ring member 112 . The rotating member 111 is rotatable relative to the first axis 101 , and one side of the rotating member 111 has a fixing recess 113 . The ring member 112 can fit on the rotating member 111 , so that the side of the rotating member 111 with the fixing recess 113 protrudes from the side of the ring member 112 . In other words, the vertical projection of the side of the rotating member 111 having the fixing recess 113 on the plane parallel to the first axis 101 is protruding from the vertical projection of the ring member 112 on the plane parallel to the first axis 101 . Wherein, the ring member 112 can at least partially extend out of the operating surface 610 (see FIG. 2A ).

In the embodiment shown in FIGS. 3A to 3C , the control member 200 has a fixing convex portion 230 facing the side of the rotating member 111 having the fixing concave portion 113 . Further, the fixing member 100 includes a plurality of rotating wheels 110, the control member 200 is a sheet including a plurality of hollow parts 280 and a plurality of fixing protrusions 230, and each of the plurality of rotating wheels 110 respectively extends into a plurality of hollow parts 280 , each of the plurality of fixing protrusions 230 is respectively disposed between the plurality of hollow parts 280 , and can respectively enter into the fixing recess 113 of one of the plurality of rotating wheels 110 .

Outside one side, each of the plurality of fixing protrusions 230 is respectively disposed on one of the plurality of support arms 290 and can enter into the fixing recess 113 of one of the plurality of rotating wheels 110 .

In the embodiment shown in FIGS. 3A to 3C , when the fixing member 100 is rotated to the locked position, the fixing concave portion 113 and the fixing convex portion 230 are misaligned, and the fixing convex portion 230 cannot enter the fixing concave portion 113 . Therefore, the second end portion 220 abuts against the moving part 300 to restrict the moving part 300 from moving toward the fixing part 100 . Wherein, the control member 200 may include a second elastic member 242 (see FIG. 5C ), which provides elastic force to move the moving member 300 away from the fixing member 100 .

More specifically, the second end portion 220 includes an end edge 221 of the control element and a stopper 222 that can move toward the end edge 221 of the control element and abut against the end edge 221 of the control element. Wherein, the control member 200 includes a third elastic member 243 (see FIG. 5C ), which provides elastic force to move the stopper 222 close to the edge 221 of the control member, and the stopper 222 has a support portion 222a that can abut against the end edge 221 of the control member . When the fixing part 100 is rotated to the locked position, the stopper 222 is located on the path where the moving part 300 moves toward the fixing part 100 , thereby limiting the moving part 300 to move toward the fixing part 100 . In this way, the moving part 300 that enters the limiting part 711 can remain still to limit the movement of the limiting part 700 , thereby producing a locking effect. In this embodiment, the stopper 222 is disposed separately from the end edge 221 of the control member, however, in different embodiments, the stopper 222 may be directly connected to the end edge 221 of the control member.

In the embodiment shown in Figures 4A to 4C, when the fixing member 100 is rotated to the unlocked position, the fixing concave portion 113 corresponds to the fixing convex portion 230, and the fixing convex portion 230 can enter the fixing concave portion 113, so that the second end portion 220 is not in contact with the moving part. 330 abuts, and the restriction of the second end portion 220 on the moving part 300 moving toward the fixed part 100 is released. Therefore, the moving part 300 can move toward the fixing part 100 .

More specifically, in the embodiment shown in FIGS. 5A to 5C , the stopper 222 has an opening 223 . When the fixing member 100 is rotated to the unlocked position, the operating member 200 rotates due to the elastic force of the first elastic member 241 so that the fixing protrusion 230 enters the fixing recess 113 , thereby driving the end edge 221 of the control member to rotate. At this time, the stopper 222 approaches the end edge 221 of the control member through the elastic force provided by the third elastic member 243, and moves to the opening 223 corresponding to the moving member 300, and the restriction of the stopper 222 on the movement of the moving member 300 toward the fixed member 100 is released. The moving member 300 is allowed to move into the opening 223 . In this way, when the limiting member 700 moves, the moving member 300 can leave the limiting portion 711 without restricting its movement. Wherein, the side of the moving part 300 facing the limiting part 700 has an inclined surface 311 , so that when the limiting part 700 moves, the moving part 300 leaves the limiting part 711 more smoothly.

Based on the above, the user can pass the limiting member 700 through the object to be fixed and then extend into the casing 600 (see FIG. 1A ), and make the moving member 300 enter the limiting portion 711 . Then, dial the character wheel to make its number different from the unlocking number, that is, even if the fixed part 100 rotates to a locked position other than the first position, the movement of the moving part 300 is restricted, so that the movement of the limiting part 700 is restricted, and the object produce a locking effect. Wherein, the limiting member 700 may include a plurality of limiting portions 711 disposed at different positions, so that the limiting member 700 is inserted into the housing 600 and fixed at different positions to fix/lock objects of different sizes.

In the above embodiment, the fixing module 800 includes the control member 200 for restricting the movement of the moving member 300 so as to achieve the effect of fixing the limiting member 700 . However, in different embodiments, the fixed module 800 is changed according to manufacturing, design or use considerations, such as using other existing combination locks without control parts, and restricting the movement of the moving parts through elements such as shafts, so as to achieve The effect of the fixed limiter.
