Detailed Description
The following describes a specific embodiment of the present embodiment with reference to the drawings.
Fig. 1 is a side view of the present invention. Fig. 2 is a front view of the guide head of the present invention. Fig. 3 is a side view of the magazine main body of the present invention. As shown in fig. 1, 2 and 3, the utility model discloses a storage type nail tail breaker. The direction of X in the figure is the upper end of the side view of the utility model, and the direction of Y in the figure is the right end of the side view of the utility model. The warehouse type nail tail breaker comprises a warehouse box main body 1 with a through structure and a guide head 2 with a hollow structure. The inner surface of the guide head 2 is provided with a plunger 3. One end of the cartridge main body 1 is provided with a plunger through hole 4. The plunger 3 moves along the plunger through hole 4 and drives the guide head 2 to move and connect with the outer surface of the cartridge main body 1.
Two plungers 3 are symmetrically arranged on the inner surface of the guide head 2. Two plunger through holes 4 are symmetrically formed in the inner surface of one end of the cartridge main body 1.
The cartridge main body 1 is a cuboid structure. The guide head 2 is of a cuboid structure. The magazine body 1 plays a role of storing the broken nail tail. The guide head 2 plays a role of guiding. The guide head 2 is mounted at the left end of the cartridge body 1. The guide head 2 is installed at the left end of the outer surface of the cartridge main body 1.
Fig. 1 is a side view of the present invention. Fig. 4 is a top view of the magazine main body of the present invention. Referring to fig. 1 and 4, a magazine observation hole 5 is formed in the outer surface of the magazine main body 1. Preferably, the cartridge viewing aperture 5 is rectangular.
