Abstract

The utility model discloses a high-speed nailing device nail tube. The structural feature of the utility model is that one end which is near the port of a nail tube 1 is provided with a boss 3 which is positioned inside the nail tube 1. Because the utility model adopts following project: it is provided with a boss at or near the port position; a nailing nail 4 is positioned inside the nail tube 1 which is at one side of the boss; the length of the nailing nail 4 is shorter than that of the nail tube; thus, when nailing, flying speed of the nailing nail can be improved and the fixed solid can not rupture, in addition, recoil of nailing is extremely small and operation is comfortable.

Description

High-speed type ail shooter nail pipe

One, technical field:

The utility model relates to a kind of accessory of ail shooter, especially high-speed type ail shooter nail pipe.

Two, prior art:

At present, the nail pipe of ail shooter is a kind of central through hole tubular construction, and the firing pin sleeve pipe inserts in the nail pipe, and its length is not less than the whole through hole length of nail pipe, dress nailing, grain (nail shooting pill) and firing pin in the nail pipe, and grain and firing pin are positioned at the back of nailing.When work, nailing directly contacts with fastened basal plane.Preshot pushes grain, firing pin, firing pin sleeve pipe, striker post, the hammer of back by the pressure between nailing and fastened body, promptly compresses mainspring; During shooting, mainspring promotes hammer, firing pin, makes the powder burning in the grain, flies forward thereby promote nailing.Because nailing contacts with fastened, so the nailing flying speed is less always, fastened body easily produces and breaks, and the recoil during shooting is big, operates uncomfortable.

Three, summary of the invention:

The purpose of this utility model provides a kind of high-speed type ail shooter nail pipe, by changing the nail tubular construction, solves ail shooter when shooting, and the nailing flying speed is little, the problem that fastened body easily breaks.

Concrete scheme of the present utility model is:

A kind of high-speed type ail shooter nail pipe, the nail pipe is the central through hole pipe, its key is: be provided with boss at the end near the nail pipe port, this boss is positioned at the nail pore.

The utility model is provided with boss in the nail pipe, it is a side that nailing is contained in boss, grain, firing pin are contained in the opposite side of boss, because boss is positioned at the place of port or close port, therefore grain, firing pin sleeve pipe, the firing pin outside or the small part that are positioned at the nail pipe stretches into the nail pipe, main dress nailing in the nail pipe.Because of nailing length less than the nail length of tube, preshot, the nail pipe directly contacts with fastened basal plane, push grain, firing pin sleeve pipe, firing pin, striker post, the hammer of back by the pressure between nail pipe and fastened body, promptly compress mainspring, during shooting, mainspring promotes hammer, firing pin, make the powder burning in the grain, fly forward thereby promote nailing.Since nailing with fastened between at regular intervals, so the nailing flying speed is bigger, fastened body is difficult for generation and breaks.

Adopt such scheme, simple in structure, easy for installation, can improve the nailing flying speed, fastened body can not break, and the recoil during shooting is minimum, operates comfortable.

Four, description of drawings:

Fig. 1 is the structure chart of first kind of embodiment of the utility model;

Fig. 2 is the structure chart of second kind of embodiment of the utility model;

Fig. 3 is this Fig. 1 and ail shooter periphery part annexation figure;

Fig. 4 is Fig. 2 and ail shooter periphery part annexation figure;

Fig. 5 is equipped with ail shooter structure chart of the present utility model.

Five, the specific embodiment:

Please see Figure 1, Fig. 2, nail pipe 1 described in the utility model is the central through hole pipe, its structural feature is: be provided with boss 3 at the end near nail pipe 1 port, this boss is positioned at nail pipe 1 hole.

As described in Figure 3: grain 8 is positioned at nail pipe 1, and firing pin sleeve pipe 6, firing pin 7 small parts stretch in the nail pipe 1.Boss 3 has segment distance apart from nail pipe 1 port, but near port.

As shown in Figure 4: grain 8, firing pin sleeve pipe 6, firing pin 7 are positioned at the outside of nail pipe 1, and boss 3 is positioned at nail pipe 1 port.

Can see from Fig. 3, Fig. 4: nailing 4 is contained in a side of boss 3, and grain, firing pin are contained in the opposite side of boss 3; Nailing 4 is positioned at nail pipe 1, and its length is shorter than nail pipe 1 length.

Operation principle of the present utility model is (as shown in Figure 5): preshot, and the pressure between nail pipe 1 and the fastened body pushes cartridge chamber body 9, grain 8, firing pin sleeve pipe 6 and hammer 11 backward, promptly compresses mainspring 12; During shooting, mainspring 12 promotes hammer 11, firing pin 7 travels forward, and makes the powder burning in the grain 8, flies forward thereby promote nailing 4.Since nailing 4 with fastened between at regular intervals, so nailing 4 flying speeds are bigger, fastened body is difficult for generation and breaks.

Claims

1. a high-speed type ail shooter nail is managed, and nail pipe (1) is the central through hole pipe, it is characterized in that: be provided with boss (3) at an end of managing (1) port near nail, this boss is positioned at nail pipe (1) hole.
