Abstract

The utility model relates to a more practical auxiliary device for a hand hammer withdrawing nails, which withdraws out straight nails and makes the straight nails to be reused, based on the lever principle. The auxiliary device is composed of a draw rod hinged with the middle piece of a hammer handle, and the support rod of the draw rod, which is hinged with one end of a hammer head. The utility model has simple structure, convenient carrying and high work efficiency.

Description

Auxiliary device with withdrawing or holding nail for hand hmmer

The utility model relates to and a kind ofly utilizes that lever principle trips out, clamping is directly followed closely, and makes its reusable hand hammer play the attachment device of straight nail.

Nail nipping instrument such as the claw hammer that uses certainly will cause the nail bending in the nail nipping process at present.The long more camber of nail is also big more, and is difficult to aligning and reuses, thereby causes the waste of nail.

The purpose of this utility model be to avoid above-mentioned weak point of the prior art and provide a kind of simple in structure, be easy to carry, high efficiency, utilize lever principle to trip out straight nail and make its reusable hand hammer play the attachment device of straight nail.

The purpose of this utility model can reach by following measure: this hand hammer plays the attachment device of straight nail, have: hammer handle, tup, hammer body and hammer folder, its special character is: the stage casing of hammer handle is positioned at the end hinged support bar of articulated elements of tup one end with the hinged pull bar of articulated elements, pull bar.

The purpose of this utility model can also reach by following measure: the length of support bar is greater than the length of nail, and the angle that support bar and pull bar initial state are constituted is an acute angle.

The drawing of accompanying drawing is described as follows:

Fig. 1 is the structural representation that hand hammer plays straight nail attachment device.

To be described in further detail in conjunction with the accompanying drawings under the utility model:

As shown in the figure, this device is by hammering into shape 1, hammer embeds 1 one ends the hammer body of self leaving in the groove 5, the hammer folder 6 of hammer body 5 upper end one, the tup 4 of hammer body 5 lower end one, hammer is adorned 1 stage casing with pin 2 hinges pull bar 8, pull bar 8 are positioned at tup 4 one end ends and form with pin 2 ' hinged support bar 3.The length of support bar 3 should be greater than the length of nail 7, and support bar 3 should be an acute angle with the angle that pull bar 8 initial states are constituted.

During use, nail clipping trough (not shown)s of leaving in the middle of this device tup 6 are enclosed within on 7 of the nails, this moment, support bar 3 withstood on the plane that nail 7 hammered into, upwards move pull bar 8, active force is by pin 2,2 ' respectively affact on claw hammer and the support bar 3, make whole claw hammer along straight line to top offset, nail nail 7 is planar tripped out by straight line thus, in the nail nipping process, pull bar 8 and support bar 3 are when initial state, and the angle that is constituted is an acute angle, along with nail 7 is tripped out, the angle that pull bar 8 and support bar 3 are constituted also by acute angle gradually to the obtuse angle transition, tripped out up to nail 7.After nail nipping finishes, pull bar 8 upwards can be moved to and hammered into shape the position that overlaps, pull bar 8, support bar 3 are superimposed together 1, with hammer so that carry to 1.

The utility model has following advantage compared to existing technology:

1, improves the repeat usage of nail, thereby reduced consumption.

2, during not nail nipping, this attachment device can be superimposed together with hand hammer, thus make carry comparatively convenient.

3, owing to utilized lever principle, make the course of work time saving and energy saving, improved operating efficiency.

4,, thereby had very big practicality because cost is lower, simple in structure, easy to use.

Claims

1, a kind of hand hammer plays the attachment device of straight nail, has: hammer handle, tup, hammer body and hammer folder into shape, it is characterized in that: the stage casing of hammer handle is positioned at the end hinged support bar of articulated elements of tup one end with the hinged pull bar of articulated elements, pull bar.

2, play the attachment device of straight nail according to the described hand hammer of claim 1, it is characterized in that: the length of support bar should be greater than the length of nail, and the angle that support bar and pull bar initial state are constituted is an acute angle.
