Compared with the prior art, the utility model outstanding advantage is:

1. the utility model adopts the structure that the rotary cylinder is arranged beside the pneumatic scissors, and the upper end of the rotary cylinder is connected with the longitudinal plate and the transverse plate which are connected with each other, so that the pneumatic scissors can have a certain protection function in an unused state, and a user is prevented from being scratched by the pneumatic scissors;

2. the utility model further arranges a chute on the working frame, which is convenient for adjusting the position of the rotary cylinder on the working frame, so as to satisfy the protection function of the pneumatic scissors with different specifications;

3. the baffle plate of the utility model can wrap the pneumatic scissors from a plurality of surfaces, so that the protection effect is better;

4. the transverse plates, the longitudinal plates and the baffle plates are made of hard alloy materials, so that the utility model is more durable;

description of the drawings:

FIG. 1 is a schematic structural view of the present invention when the rotary cylinder is not rotating;

FIG. 2 is a schematic view of the structure of the rotary cylinder of the present invention during rotation;

in the figure:

1-a working frame; 10-a chute; 2-pneumatic scissors; 3-rotating the cylinder; 30-a cylinder; 31-a piston rod; 32-a slide block; 4-a transverse plate; 40-longitudinal plates; 41-baffle.

The specific implementation mode is as follows:

the invention will now be further described with reference to specific embodiments, with reference to figures 1 to 2:

a protective device of pneumatic scissors comprises pneumatic scissors 2 fixed on a working frame 1, a rotary cylinder 3 is arranged on the working frame 1, a cylinder 30 of the rotary cylinder 3 is positioned at one side of the pneumatic scissors 2, a transverse plate 4 is fixed on a piston rod 31 of the rotary cylinder 3, a longitudinal plate 40 is formed downwards on one side of the transverse plate 4, when the rotary cylinder 3 rotates the piston rod 31, the transverse plate 4 covers the top of the pneumatic scissors 2, the longitudinal plate 40 is pressed against the side wall of the pneumatic scissors 2, the rotary cylinder 3 and the pneumatic scissors 2 work independently and respectively, when the pneumatic scissors are not used, the piston rod 31 of the rotary cylinder 3 is in a state of rising and rotating, the transverse plate 4 is covered on the sharp scissors edge of the pneumatic scissors 2, the longitudinal plate 40 blocks the side wall of the pneumatic scissors, and the pneumatic scissors are in a state that the lateral plate 4 and the longitudinal plate 40 block the pneumatic scissors and cannot be used any more;

it is worth mentioning that conventional pneumatic scissors have handheld position and lie in the structure of tailorring at handheld position upper end, tailorring the structure between the diaphragm and protecting, and the longitudinal plate offsets handheld portion for pneumatic scissors can't contact with the user on the whole, thereby promotes production factor of safety.

Preferably, the working frame 1 is provided with a sliding groove 10, one side of the rotary cylinder 3 is provided with a sliding block 32 which is used for sliding in the sliding groove 10, the sliding block 32 and the sliding groove 10 which are matched with each other are convenient for the rotary cylinder to move left and right, and the problem that the distance between the rotary cylinder and the pneumatic scissors is different due to the different specifications of the pneumatic scissors is solved.
