What is configured by separating the silicon-loaded body 10 into a plurality of different sizes to load various silicon tubes;

forming a coupling piece 12 at the rear end of the silicon-loaded body 10;

The silicon gun is completed by configuring the coupling protrusion 26 at the tip of the trigger bundle to separate and couple the silicon loading bodies 10 of different sizes constituting the loading chamber 11 to load the various silicone tubes.

And a silicon loading body 10 having a loading chamber 11 for mounting a silicone tube; The silicon loading body 10 is coupled, and a bolt 23 coupled to the tip of the pressure plate 24 for pressing the piston of the silicon tube loaded in the silicone loading body 10, and a trigger for advancing the bolt 23 In the silicone gun trigger bundle comprising a lever (30), a locking piece (25) for intermittent retraction of the bolt (23), and a handle (21) to shoot silicon filled in a silicone tube forward to work,

What constitutes the cylinder bearing 40 sliding forward and backward in the bolt guide hole 22 through which the bolt 23 of the trigger bundle constituting the handle 21 passes;

The cylinder bearing 40 is formed with a locking jaw 41 on the outer periphery of the rear end and an 0-ring coupling groove 42 is formed on the inner periphery of the rear end to combine the 0-ring 50;

a bolt 23 is inserted into the cylinder bearing 40 so that the 0-ring 50 causes friction with the bolt 23;

The upper end of the 0-ring (50) is configured to push the lock piece (25) back, thereby completing the silicone gun trigger assembly.

Here, the trigger bundle constitutes the clamper 31 so that the clamping hole 32 is coupled to the bolt 23 and pressed backwards with the spring 35, and the lower end of the clamper 31 is configured on the upper side of the trigger lever 30. that the bush 36 is pushed;

The clamping hole 32 of the clamper 31, which moves forward and backward by the trigger lever 30, is completed in the form of at least a pentagonal shape.

An exemplary embodiment of the present invention will be described as follows.

First, by fastening the coupling piece 12 by hooking the silicon loading body 10 to the coupling protrusion 26 of the trigger bundle, the silicone loading body 10 and the trigger bundle are integrally coupled to form a silicon gun.

At this time, the silicon loading body 10 and the trigger bundle may be integrally combined and configured to be used.

In the above state, the silicon tube filled with silicon is loaded in the loading chamber 11 of the silicon loading body 10, and the pressing plate 24 constructed at the tip of the bolt 23 by advancing the bolt 23 is the piston of the cylinder tube. make it adhere to

In this state, when the user grabs the handle 21 of the trigger bundle and pulls the trigger lever 30, the rolling bush 36 formed at the upper end of the trigger lever 30 pushes the lower end of the clamper 31, the clamper 31 As the lower end is inclined forward, the upper front and lower rear of the clamping hole 32 bite the bolt 23 and press the spring 35 to advance the bolt 23,

At this time, the cylinder bearing 40 coupled to the bolt guide hole 22 advances while the O-ring 50 coupled to the O-ring coupling groove 42 at the rear end is coupled to the outer edge of the bolt 23 to generate friction. (41) is caught and stopped, and is pushed back by the 0-ring (50) and the locking piece (25) biting the upper and lower sides of the bolt (23) stands upright and guides the smooth advancement of the bolt (23).

At this time, if the clamping hole 32 of the clamper 31 and the hole of the locking piece 25 are formed to be at least pentagonal rather than circular, when they bite the bolt 23, they make point contact rather than line contact. It will be sure to bite and hold without slipping even in use.

In this way, as the bolt 23 advances, the pressure plate 24 pushes the piston of the cylinder tube, and then releases the trigger lever 30 by releasing the grip force pulled by the user. When the lower end of the clamper 31 pushes the rolling bush 36 at the upper end of the trigger lever 30 backward while returning to the straight state by returning the tilted state, the trigger lever 30 is returned to the original position and the bolt (23) It is also retreated back by the pressure of the silicon tube, at this time, while the cylinder bearing 40 is retracted together, the upper end of the O-ring 50 coupled to the rear end of the cylinder bearing 40 pushes the locking piece 25. , as the upper end of the hinged lock piece 25 is tilted, the hole of the lock piece 25 catches the bolt 23 to prevent the bolt 23 from retreating.

At this time, as the bolt 23 retracts as much as the retracting operation of the cylinder bearing 40, the pressurization in the silicon tube is removed.

When this state is repeated to exhaust the silicon loaded in the silicon tube and grind the silicon tube, when the lower end of the lock piece 25 is forcibly pushed forward, the lock piece 25 presses the 0-ring 50 and the cylinder As the bearing 40 advances and the locking piece 25 stands upright, the hole of the locking piece 25 that bit the bolt 23 frees the bolt 23 so that retraction of the bolt 23 is possible, at this time the bolt (23) is retracted to replace the silicone tube with a new one,

The present invention as described above can be usefully used at a construction site, etc., and it will be said that the industrial use value is great.
