Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

The following describes an embodiment of the present invention according to its overall structure.

A pair of small pneumatic scissors is shown in figures 1, 2, 3 and 4 and comprises a shell 1, a left shear arm 4 and a right shear arm 5, wherein a protection component 6 is arranged on the shell 1.

Specifically, protection component 6 is including being used for assisting pneumatic scissors to remove and the spout 601 that the pneumatic scissors of control opened and shut, and left side arm 4 and right side 5 surfaces of cutting and the back all are connected with and are used for the slider 602 to the pneumatic scissors direction, and shell 1 top is connected with and is used for sheltering from being connected with apron 603 of pneumatic scissors, and apron 603 both sides all are connected with the torsional spring 604 that is used for driving apron 603 to reset, can effectively reduce the potential safety hazard of scissors arm point portion to external production.

Referring to fig. 1, 2, 3 and 4, in the above embodiment, the cylinder 2 is installed at one side of the housing 1, the output end of the cylinder 2 is connected with the pushing frame 3 through the piston rod, the left shearing arm 4 and the right shearing arm 5 are respectively connected to two sides inside the pushing frame 3, and the rotating shaft 7 is connected between the left shearing arm 4, the right shearing arm 5 and the pushing frame 3, so that the material can be automatically sheared conveniently.

Referring to fig. 1, 2, 3 and 4, in the above embodiment, the left shear arm 4 and the right shear arm 5 are rotatably connected to the pushing frame 3 through the rotating shaft 7, the tops of the left shear arm 4 and the right shear arm 5 are circular, the pushing frame 3 is slidably connected to the housing 1, and the left shear arm 4 and the right shear arm 5 are slidably connected to the housing 1 through the sliding groove 601 and the sliding block 602, so that the injury to the worker is reduced.

Referring to fig. 1, 2, 3 and 4, in the above embodiment, two sides of the top of the sliding groove 601 are in a slope shape, the sliding block 602 is in a cylindrical shape, the cover plate 603 is rotatably connected with the housing 1 through a hinge, the cover plate 603 is adapted to the housing 1, and the sliding block 602 is adapted to the sliding groove 601, so that potential safety hazards caused by the tip of the scissor arm to the outside can be effectively reduced.

The implementation principle of the embodiment is as follows: firstly, the pneumatic scissors are positioned in the shell 1 in a non-working state, so that the phenomenon that the sharp part of the scissor arm stabs a worker is effectively reduced, meanwhile, the safety is further improved through the arrangement of the cover plate 603, and meanwhile, the sharp parts of the left scissor arm 4 and the right scissor arm 5 are in a round shape after chamfering treatment, so that the pressure bearing area of the worker is increased when the pneumatic scissors are in contact with the worker, the pressure is reduced, the injury is reduced, and the sharp parts of the left scissor arm 4 and the right scissor arm 5 are not too sharp any more, so that the injury to the worker is further reduced;

the material is cut, the output end of the cylinder 2 pushes the push frame 3 through the piston rod so that the pneumatic scissors extend out of the shell 1, meanwhile, the cover plate 603 is stressed to rotate and open to compress the torsion spring 604, the sliding block 602 enters the slope position of the sliding groove 601 after linear displacement of the sliding block 602 for a certain distance, pressure is applied to the sliding block 602 through the slope position of the sliding groove 601 so that the sliding block 602 slides obliquely, and therefore the bottoms of the left shearing arm 4 and the right shearing arm 5 are pressed, and the pneumatic scissors are closed to cut the material;

after the materials are retracted and cut off, the output end of the air cylinder 2 pulls the push frame 3 through the piston rod, so that the pneumatic scissors are retracted into the shell 1, meanwhile, the pneumatic scissors are opened under the influence of the slope position of the chute 601, then the pneumatic scissors are completely retracted into the shell 1, and meanwhile, the torsion spring 604 loses pressure to drive the cover plate 603 to reset to shield the shell 1.
