Description

Technical Field

[0001] The utility model relates to the technical field of insulating scissors, in particular to an electric shock prevention shearing device. Background Art

[0002] Insulated scissors are commonly used tools in power engineering and the power industry; the main feature of insulated scissors is that both the blade and the handle have good insulation properties, which can effectively prevent electric current from passing through the scissors and causing electric shock accidents.

[0003] The prior art discloses a patent with application number CN202223086652.0, which provides an insulating pair of scissors, comprising scissor blades, a scissor drive block, a connecting seat, a connecting block, a connecting structure and a scissor handle, wherein two scissor blades are arranged facing each other, and the scissor blades are connected to the scissor drive block. A cavity is provided in the connecting seat, and two scissor drive blocks are provided in the cavity. A guide rod is provided in the cavity, and the guide rod passes through the scissor drive block and is installed on the inner wall of the cavity of the connecting seat, and the scissor drive block can move along the guide rod. A through opening is symmetrically provided on the side wall of the connecting seat near the scissor drive block, and the connecting block is connected to the scissor drive block, and the through opening of the connecting block is connected to the scissor handle through the connecting structure, and the scissor handle can drive the scissor blades to move toward or away from each other through the connecting structure.

At this time, the workers may not be able to significantly change the operating position of their hands. Therefore, when using the above-mentioned insulating scissors, the target object may not be cut due to the fixed length of the handles. In addition, the handles of the above-mentioned insulating scissors have a large overall size formed by crossing during operation, which is not convenient for use in narrow environments.

The two mounting seats 2 8 are respectively arranged at two end positions of the first mounting plate 1. A hollow shaft 9 is rotatably mounted between the two mounting seats 2 8, and both ends of the hollow shaft 9 rotate through the mounting seats 2 8 at corresponding positions.

[0034] Two limiting grooves 10 are provided on the side of the hollow shaft 9 and are arranged parallel to the hollow shaft 9. A worm gear 14 is fixedly installed at one end of the hollow shaft 9 close to the driving assembly.

[0035] A transmission rod 6 coaxially arranged with the hollow shaft 9 is rotatably installed in the mounting seat 1 7, a bevel gear 21 is fixedly installed at one end of the transmission rod 6 close to the shearing assembly, and the other end of the transmission rod 6 is slidably inserted into the interior of the hollow shaft 9;

[0036] Two protrusions 11 are fixedly mounted on the periphery of the transmission rod 6 at one end located inside the hollow shaft 9 . The two protrusions 11 extend into two limiting grooves 10 respectively at one end away from the transmission rod 6 , and the protrusions 11 are in sliding contact with the limiting grooves 10 .
