Description

The percussion lock of extension bar formula nail hitting machine

The utility model relates to the percussion lock of a kind of extension bar formula nail hitting machine.

The nail hitting machine is used quite widely in the decoration industry, and relevant manufacturer also develops multiple different structure according to its different design concept, can have more diversified selection according to its demand for the user.

But existing this type of nail hitting machine structure, its design principle is still with the design of gun identical, that is it is to handle firing pin percussion gunpowder with a trigger mostly, to push piston rod the steel nail that is assembled in the front end nail sleeve pipe is hit, but under some situation, the user must hold the nail hitting machine high to ceiling or extend to apart from user's one segment distance and use, so having manufacturer to develop " extension bar formula nail hitting machine ", it mainly is to be provided with the structure that can be connected in series mutually with extension bar (extension rod) at nail hitting machine end, carry out the nail hitting operation and can allow the user that the stretching, extension of nail hitting machine is inserted into suitable position, this type of extension bar formula nail hitting machine is developed when finishing the earliest, only be that general nail hitting machine end is set up the structure that is connected in series with extension bar, its trigger then carries out traction control with a rope, to reach the effect that the nail hitting machine is extended to nail hitting at a distance.

But aforesaid extension bar formula nail hitting machine design is very difficult on handling, especially the setting of plate machine is not coaxial with the nail sleeve pipe of nail hitting machine, that is when the pulling rope triggers trigger, can on the nail hitting machine, produce a side force, and need the nail sleeve pipe front end of nail hitting position to be offset on the feasible alignment pieces originally, and can make the nail hitting operation slip up, this promptly is the shortcoming in such design.

In view of above-mentioned prior art problems, the utility model main purpose is: the percussion lock of a kind of extension bar formula nail hitting machine is provided, and this device can be guaranteed the correct position of pulling the trigger.

The another purpose of the utility model is: the percussion lock of a kind of extension bar formula nail hitting machine is provided, and this device can reach the effect of control percussion.

The utility model purpose again is: the percussion lock of a kind of extension bar formula nail hitting machine is provided, and this device can set back after percussion automatically.

The technical solution of the utility model is to provide the percussion lock of a kind of extension bar formula nail hitting machine, its characteristic is that the firing pin side is provided with an assembling grove, in this assembling grove, be equipped with the controll block by the outside ejection of little spring, the controll block leading edge is fastened on igniter cap cover trailing edge, the firing pin rear end is sheathed in the striker post, be equipped with the percussion spring of ejection firing pin in the striker post, striker post and igniter cap inner room are provided with backspring, and the striker post rear end is connected with extension bar mutually with the extension bar seat.

The utility model compared with the prior art advantage and good effect is very obvious.By above technical scheme as can be known, the extension bar formula nail hitting machine percussion lock that the utility model provides, by appropriate respective outer side edges, can promote striker post through the extension bar seat by extension bar, and and then the controll block of control on the firing pin, so can push the percussion that firing pin carries out gunpowder, so can accurately control the impact of firing pin to gunpowder by the percussion spring, unlikely, have to be difficult for the accurately shortcoming of control percussion power when controlling by manpower as existing.Again, the utility model is by the cooperation of backspring and dependency structure, more can be when extension bar strength discharge, even each member homing partly, so that carry out next time nail hitting operation, its true tool operation convenience.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.In the accompanying drawing:
