Description

Prevent down nail rifle

Technical Field

The utility model relates to a nail rifle is a nail rifle that can prevent to fall the nail after T shape nail is beaten out particularly.

Background

The nail needle that general nail rifle percussion can be divided into forms such as T-shaped nail, staple and U-shaped nail according to the form, conveniently matches the demand of different operations. Various nails are often needed to be matched for use during operation, and if nails in various shapes need to be matched with a special nail gun, great inconvenience is brought to workers.

The existing nail gun can be adapted to nails with different shapes, and new problems are caused by the fact that T-shaped nails are narrower than U-shaped nails and U-shaped nails, and a section of idle stroke is often arranged in the nail gun before the T-shaped nails are driven out, so that the T-shaped nails are easy to topple and bend or cannot be nailed in place during the idle stroke, for example, a nail gun nail box structure disclosed in Chinese patent literature, the publication number of which is CN2670065Y, comprises a nail box body which is long and narrow and is internally provided with a long axial accommodating groove; the nail striking seat is combined at the front end of the nail box body, the lower section of the nail striking seat is provided with a notch, and the notch penetrates through the front side surface and the rear side surface of the nail striking seat and is communicated with the accommodating groove; the nail guiding piece is in a strip shape and penetrates through the accommodating groove, and various nails can be stably placed on the nail guiding piece; the pushing component is arranged in the nail box body and comprises a nail pushing piece and an elastic piece, and the nail pushing piece pushes the nail towards the direction of the notch of the nail striking seat under the traction action of the elastic piece; the nail striking seat is provided with a first needle groove which extends upwards from the middle position of the top edge of the notch to form a long and narrow shape; the limiting seat is positioned in the notch of the nail striking seat, the top surface, the left side surface and the right side surface of the limiting seat and the inner wall of the notch are separated by a preset gap to jointly form a second needle groove, the limiting seat is further provided with a cutting groove downwards from the middle position of the top surface, and the cutting groove is connected with the first needle groove; by adopting the structure, when the T-shaped nail is accommodated in the nail box, the T-shaped nail can pass through the first needle groove and the cutting groove, and the nail body of the T-shaped nail is always consistent with the impact axis of the firing pin of the nail gun, so that the aim of nailing can be achieved straightly and solidly when the T-shaped nail is impacted by the firing pin. The disadvantage of this nail gun is that it does not take into account that the T-shaped nail, especially the small size T-shaped nail, has a section of idle stroke before being driven out, and the T-shaped nail is easy to fall due to the unbalanced force applied by the driving nail in the process.

SUMMERY OF THE UTILITY MODEL

In order to overcome the problem that nail gun among the prior art appears falling the nail phenomenon easily because the existence of idle stroke when beating T shape nail, the utility model provides a prevent down nail rifle that nail phenomenon can play to prevent to fall nail phenomenon to T shape nail.

The utility model discloses a realize through following technical scheme:
