Description

[Detailed Description of the Invention] This invention relates to a cartridge gun that is a cartridge containing a material to be extruded, such as a sticky filler, a sealant, or an adhesive.

Conventionally, sticky fillers, sealants, adhesives, etc. have been filled in resin containers with a nozzle at the tip and a piston at the rear and supplied in the form of a car container. The tapered nozzle part sealed by integral molding is cut at different longitudinal positions and angles to create an appropriate opening.When installing, set the cartridge in the holding part of the cartridge gun and use the cartridge gun to remove the piston. The contents are pushed out through a nozzle with an open tip.

However, such a cartridge requires a cutting tool such as scissors or a knife to cut the tapered tip nozzle at an appropriate position, but this is often not available at hand, and time may be wasted searching for it.

This invention was made to find a method for cutting the tapered nozzle of the cartridge without using anything other than the cartridge and the cartridge gun, and provides a cartridge gun that can also cut the nozzle part of the cartridge. The purpose is to

In this invention, a grip provided on a cartridge gun is provided with a hole or groove for inserting and holding a tapered nozzle of a cartridge, and a cutting edge is formed on a trigger pivotally attached to the grip.

The pin 15 is pushed to the left in FIG. 1 and the trigger 12 is rotated to the position shown by the solid line in FIG.
is rotated counterclockwise around pin 11 to restore its original state.

At this time, the guard 26 performs the same restoring action as when the taper nozzle 4 was previously cut.

By repeating the same operation, the piston 3 is pushed into the container 2 little by little, and the extruded agent is extruded from the end of the tapered nozzle 4.

To return the bushing rod 14 to its original position, press the check piece 19 in FIG. When pulled by the part on which the hand is placed, it becomes possible to slide through the holes of the bearing 9, the grip 9, and the feed piece 16, and the holding plate 13 is moved to the outside of the container 2 and the cartridge 1 is removed.
can be removed.

As mentioned above, the nozzle part can be cut to the required size when the cartridge is set in the cartridge gun, making it easy to work with. Depending on the size of the work area, the shape of the cut can be selected using the round or long hole provided in the grip. Can be done.

Since there is no need to prepare a cutting tool for the cartridge nozzle other than the cartridge gun, the work can be started immediately without having to take any precautions when preparing for work.

The structure is simple, the lever ratio is large, and the nozzle part can be cut by a light force.

As shown in the embodiment, when the nozzle of the cartridge is a tapered nozzle, if the size of the hole provided in the grip is indicated, the nozzle can be inserted into the reading tag, thereby making it possible to accurately cut the desired size.
