[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , including: a travel switch body 1 and a switch connecting shaft 2 rotatably connected to the surface of the travel switch body 1. The connection between the switch connecting shaft 2 and the travel switch body 1 can rotate freely. As the switch connecting shaft 2 rotates, an adjusting cross plate 3 fixedly connected to the surface of the switch connecting shaft 2 can also rotate. A downward groove is opened at the top of the adjusting cross plate 3, and a cross plate screw part 4 is horizontally inserted into the groove. One end of the cross plate screw part 4 rotates with the inner wall of the groove, and the other end passes out of the groove and is provided with a handle part. A moving block meshingly sleeved outside the cross plate screw part 4 is also arranged in the groove. The cross plate screw part 4 can drive the moving block to move radially along the groove, and a supporting vertical rod 5 is fixedly arranged on the top of the moving block, so that the supporting vertical rod 5 can also move radially along the groove.

[0024] Vertical rod chutes 6 are opened on both sides of the supporting vertical rod 5. An adjusting slider part 7 is slidably installed in the slots of the vertical rod chutes 6. A bolt is installed at the center of the adjusting slider part 7. The adjusting slider part 7 can move radially along the vertical rod chutes 6, so as to adjust the height of the adjusting slider part 7. After the position adjustment of the adjusting slider part 7 is completed, the position of the adjusting slider part 7 can be fixed by the bolt. A rotatable rotary adjusting plate 12 is arranged on the outer wall of the adjusting slider part 7, and a plurality of groups of positioning slot parts 9 are annularly and evenly distributed on the surface of the rotary adjusting plate 12. A convex plate part 10 protruding downward is fixedly arranged on the surface of the adjusting slider part 7, and a socket is opened in the convex plate part 10. A positioning plug rod 11 is inserted into the socket. The front end of the positioning plug rod 11 passes through the socket and can extend into the slot of the positioning slot part 9, so that the rotation angle of the rotary adjusting plate 12 can be limited by the positioning plug rod 11. The rotary adjusting plate 12 is installed on one side of the impact part 14. A chute is opened on the surface of the rotary adjusting plate 12, and a displacement block 13 is slidably installed in the chute. The central axis of the impact part 14 is rotatably inserted into the displacement block 13. After the displacement of the impact part 14 dragged by the displacement block 13 needs to be fixed, the bolts on both sides of the displacement block 13 can be operated to fix the positions of the displacement block 13 and the rotary adjusting plate 12.

[0025] The impact member 14 is installed above the travel switch body 1. An impact groove 15 is formed on the outer wall of the impact member 14. A number of groups of impact rollers 16 are installed in the groove of the impact groove 15. The roller positioning rod 17 is disposed through the edge portion of the transverse plate screw portion 4. The front end of the roller positioning rod 17 extends into the groove of the impact groove 15 and is rotatably connected to the inner cavity of the impact roller 16. A jack is provided at the central portion of the impact roller 16. When assembling the impact roller 16, align the jack of the impact roller 16 with the opening formed in the frame of the support vertical rod 5, and then pass the adjusting slider portion 7 through the vertical rod chute 6 and the support vertical rod 5, and reinforce it with a nut at the end of the roller positioning rod 17, thereby completing the installation of the position of the impact roller 16. When the entire impact member 14 impacts and contacts an object, contact is made through the rotation of the impact roller 16, improving the wear resistance of the entire impact member 14. After the impact roller 16 is worn, rapid disassembly and replacement can also be achieved.

[0026] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
