Detailed Description

The invention will be further described with reference to the following drawings and examples:

the first embodiment is as follows: referring to fig. 1 to 4, a pair of pneumatic scissors comprises a first scissors body 1 and a second scissors body 2, the first scissors body and the second scissors body are connected through a pin shaft 3, a first scissors head 4 is arranged at the front end of the first scissors body, a second scissors head 5 is arranged at the front end of the second scissors body, the first scissors head is arranged right opposite to the second scissors head, a first blade 6 is arranged on the left side surface of the first scissors head, a second blade 7 matched with the first blade is arranged on the left side surface of the second scissors head, the blade of the first blade is arranged outside the inner end surface of the first scissors head in a protruding manner, the blade of the second blade is arranged flush with the inner end surface of the second scissors head, a plurality of strip-shaped protrusions 8 are arranged on the inner side surface of the first scissors head at intervals, and are arranged on the right side of the first blade in parallel, the protruding height of the strip-shaped protrusion is smaller than that of the first blade, when the first shearing clamping head and the second shearing clamping head are clamped tightly, the inner end face of the strip-shaped protrusion abuts against the inner end face of the second shearing clamping head, and the right side face of the first blade is in contact with the left side face of the second blade.

In this embodiment, in the actual use process, the enameled wire product passes through between first double-layered cutting head and the second double-layered cutting head, then first double-layered cutting head presss from both sides tightly with the second double-layered cutting head, and at this in-process, first blade and second blade contact in-process, the bar arch can be pressed the enameled wire on the interior terminal surface of second double-layered cutting head, after pushing down like this, then first blade and second blade can be given the enameled wire to cut off, like this in the enameled wire cutting process, the side of enameled wire can be pushed down, cut off in-process enameled wire like this and can not remove, can guarantee the cutting quality of enameled wire. Meanwhile, a chuck does not need to be arranged independently, and cost can be effectively reduced.

Wherein the cutting edge of the first blade is a sharp cutting edge; the cutting edge of the second blade is a plane cutting edge. The strip-shaped protrusions are arranged beside the first blade, so that clamping can be simultaneously performed in the cutting process, and the cutting quality is guaranteed.

Referring to fig. 3 and 4, the cross section of each strip-shaped protrusion is of a V-shaped structure, and a plurality of groups of strip-shaped protrusions are arranged on the right side of the first blade at intervals from left to right. The V-shaped structure is adopted, so that the contact area with the enameled wire can be reduced, and the clamping quality is improved.

Referring to fig. 4, the length of the strip-shaped protrusion is smaller than that of the first blade, and the strip-shaped protrusion is arranged opposite to the middle of the first blade. Like this can reduce cost, the protruding cutting off to the product of first blade and second blade that can not influence of bar moreover.

Wherein, a spring (not shown in the figure) is also arranged, and two ends of the spring are respectively connected with the middle part of the rear end of the first clipping body and the middle part of the rear end of the second clipping body. The pneumatic scissors are arranged on the front end of the base, the pneumatic scissors are arranged on the base, the rear end of the pneumatic scissors is connected with the pneumatic clamping base, the pneumatic scissors can be driven to be opened, the springs push the pneumatic scissors to be closed to clamp and cut off products, the springs are arranged, the size of the pneumatic scissors and clamping and cutting off corresponding to different products can be achieved, the springs with different elastic forces are adopted, clamping and cutting-off force of the pneumatic scissors on the products is guaranteed, the products can be cut off smoothly, and the products cannot be damaged due to clamping.

Example two: in this embodiment, the structure of the pneumatic scissors is substantially similar to that of the first embodiment, except that: the cross section of the strip-shaped bulge is of an arc-shaped structure.
