The utility model discloses to the not enough of existence among the above-mentioned prior art, provide a manual hole puncher.
The utility model provides an above-mentioned technical problem's technical scheme as follows:
a manual hole puncher comprises a driving lever and a driven lever, wherein the driving lever is hinged to the driven lever through a rotating shaft, a compression screw is arranged at the front end of the driving lever, and a pressure hole is formed in the position, corresponding to the compression screw, of the front end of the driven lever.
Furthermore, the compression screw penetrates through the driving lever, and the tip of the compression screw is a pressure head.
Further, the pressure head is a cone with 30 degrees.
Further, the diameter of the root of the pressure head is consistent with the diameter of a hole in the side wall of the cylinder of the warm air furnace.
Further, the diameter of the root of the pressure head is smaller than the aperture of the pressure hole.
Furthermore, the compression screw is also provided with an adjusting bolt.
Furthermore, a locking nut is further arranged on the compression screw.
Furthermore, the rear ends of the driving lever and the driven lever are respectively provided with an anti-skidding handle.
Compared with the prior art, the beneficial effects of the utility model are that: be equipped with housing screw through initiative lever front end, the driven lever front end corresponds housing screw department and is equipped with the pressure hole for the installation binding face increase and difficult burr after punching has guaranteed the appearance quality of barrel, and easy operation, security are high still do not waste the electricity, and the efficiency of punching compares the electric drill and promotes 100 times, has improved production efficiency when reduce cost.

Detailed Description
The principles and features of the present invention are described below in conjunction with the following drawings, the examples given are only intended to illustrate the present invention and are not intended to limit the scope of the present invention.
As shown in fig. 1-5, the manual hole puncher comprises a driving lever 1 and a driven lever 2, wherein the driving lever 1 is hinged to the driven lever 2 through a rotating shaft 3, a compression screw 4 is arranged at the front end of the driving lever 1, a compression hole 7 is arranged at the front end of the driven lever 2 corresponding to the compression screw 4, the distance between the rear end of the driving lever 1 and the rear end of the driven lever 2 is adjusted to be small or large, the front end of the driving lever 1 and the front end of the driven lever 2 are controlled to be meshed or separated, the operation is simple, and the safety is high.
The compression screw 4 penetrates through the driving lever 1, and the tip of the compression screw 4 is a pressure head 8.
The pressure head 8 is a cone with 30 degrees, so that the sharpness is ensured.
The diameter of the root part of the pressure head 8 is consistent with the diameter of the hole 9 on the side wall of the cylinder body of the warm air furnace.
The diameter of the root of the pressure head 8 is smaller than the aperture of the pressure hole 7, a flanging function is realized during the pressure hole, the binding surface is enlarged, and the locking capacity of the self-tapping screw is improved.
Still be equipped with adjusting bolt 5 on the housing screw 4, adjusting bolt 5 can adjust pressure head depths length, reaches the effect that changes the hole degree of depth.
And a locking nut 6 is further arranged on the compression screw 4, and once the pressure head is broken, the compression screw 4 is loosened to realize the quick replacement function.
The rear ends of the driving lever 1 and the driven lever 2 are respectively provided with an anti-skid handle 10.
During operation, the 1 rear end of initiative lever is held to one hand, the 2 rear ends of driven lever are held to one hand, the mark of punching in advance on the warm braw stove barrel lateral wall is aimed at to pressure head 8 of housing screw 4 below, reduce the interval between 1 rear end of initiative lever and the 2 rear ends of driven lever and punch, expand the interval between 1 rear end of initiative lever and the 2 rear ends of driven lever after punching and accomplish and punch, hole 9 on the lateral wall produces inward turn-ups under the effect of pressure head power, installation binding face increase and difficult burr, the appearance quality of barrel has been guaranteed, and is simple easy to operate, the security is high still does not waste the electricity, punching efficiency compares the electric drill and promotes 100 times, and the production efficiency has been improved in the time of reduce cost.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
