[0017] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with the embodiments and drawings, and the contents mentioned in the implementation modes are not intended to limit the present invention. The present invention is described in detail below in conjunction with the drawings.

[0018] A tool for cutting edges of composite insulators, such as Figure 1 to Figure 2As shown, it includes a tool holder 1, a blade 2 and a fixing assembly for fixing the blade 2, a positioning groove 3 is provided on one side of the tool holder 1; the fixing assembly includes a positioning plate 4 and two fixing screws 5 installed on the positioning plate 4, the lower end surface of the positioning plate 4 is provided with an L-shaped groove 6, the positioning plate 4 is installed on the other side of the tool holder 1, the L-shaped groove 6 is used to clamp the blade 2, the front end of the blade 2 extends from the L-shaped groove 6 and protrudes into the top of the positioning groove 3, and the other side of the tool holder 1 is provided with two screw holes 10 that are screwed with the fixing screws 5. Specifically, the utility model has a novel structure and an ingenious design. When in use, the operator can install the tool holder 1 on an external workbench, or hold the tool holder 1 by hand; when the tool holder 1 is held by hand for operation, the outer edge of the umbrella of the composite insulator is extended into the positioning groove 3, and the tool holder 1 is driven to slide along the outer edge of the umbrella, so that the blade 2 can scrape off the burrs and scraps of the outer edge of the umbrella. Due to the positioning and guiding sliding functions of the positioning groove 3, the working stability and reliability of scraping off the burrs and scraps of the outer edge of the umbrella are effectively improved, and the processing effect is good, and the operation difficulty is small. The operation is simple, fast and efficient. When the operator installs the tool holder 1 on the external workbench, the outer edge of the umbrella of the composite insulator is inserted into the positioning groove 3, the composite insulator is driven to rotate, so that the outer edge of the umbrella slides along the inner wall of the positioning groove 3. Similarly, the burrs and scraps of the outer edge of the umbrella can be cut off. In addition, by using the cooperation between the fixing component and the tool holder 1, the blade 2 can be detachably connected to the tool holder 1, which is convenient for replacement and assembly. When the blade 2 needs to be replaced, the fixing screw 5 is loosened to disengage from the screw hole 10, and the blade 2 can be removed from the tool holder 1.

[0019] Further, the blade 2 is provided with a through hole for the fixing screw 5 to pass through. Specifically, the blade 2 is screwed with the screw hole 10 after the fixing screw 5 passes through the through hole, so as to facilitate the positioning of the blade 2.

[0020] In the embodiment of the present application, anti-skid grooves 7 are respectively provided on both sides of the tool holder 1. Specifically, under the effect of the anti-skid grooves 7, when the operator holds the tool holder 1 for operation, the anti-skid grooves 7 play an anti-skid effect to prevent the operator from slipping and falling off. Furthermore, the inner wall of the anti-skid groove 7 is provided with a plurality of anti-skid diagonal strips to further improve the anti-skid effect.

[0021] In the embodiment of the present application, the cross section of the positioning groove 3 is arranged in a trumpet shape. Specifically, in this arrangement, the trumpet shape is positioned outward, which makes it easier for the outer edge of the composite insulator to extend into the positioning groove 3.

[0022] In the embodiment of the present application, at least two mounting posts 8 are provided at the lower end of the tool holder 1. Among them, an elastic sphere 9 is provided at the lower end of the mounting post 8. Specifically, when the tool holder 1 needs to be fixed on an external workbench, the mounting post 8 can be used to snap into the corresponding snap-in hole on the workbench to fix the tool holder 1; further, an elastic sphere 9 is provided at the lower end of the mounting post 8, and the elastic sphere 9 has deformation recovery ability and elastic effect. The elastic sphere 9 is used to tightly abut against the inner wall of the external snap-in hole to improve the snap-in stability and reliability between the mounting post 8 and the snap-in hole.
