[0048] Working principle: First, the user moves the support column 1 to the required working position, and then the user rotates the fixed block 22, and the fixed block 22 will be rotated horizontally through the transmission shaft 21. After rotating to a suitable angle, the user bolts the fixed block 22 to the workbench of the conveyor belt to be tested through the threaded hole 23. After the support column 1 is fixed, the user powers on the hydraulic rod 204 to start the hydraulic rod 204, and the hydraulic rod 204 will drive the support plate 201 to move downward. When the support plate 201 moves downward, the torsion spring 5 will be squeezed to generate pressure on the torsion spring 5. After the bottom of the support plate 201 contacts the bottom of the limit opening 3, the bottom of the contact ball 202 will contact the top of the conveyor belt to be tested, and the front side of the rotating wheel 18 will also contact the edge of the conveyor belt. After that, the user powers on and starts the testing machine, and the testing machine drives the conveyor belt to rotate. When the conveyor belt rotates, the friction generated on the surface will drive the contact ball 202 to move to the side where the conveyor belt rotates. When the contact ball 202 moves with the conveyor belt, it will drive the support plate 201 to follow When the support plate 201 moves, the support plate 201 will follow the contact ball 202 through the rotating shaft 203 and the rotating rod 4 to move. When the support plate 201 follows the movement, it will drive the torsion spring 5 to apply torque to the rotating side and rotate through the sliding port 6. Then, when the conveyor belt slips, the conveyor belt stops and the contact ball 202 is not driven by the friction force generated by the rotation of the conveyor belt to move, so it will stop driving the support plate 201 to follow the rotation. The support plate 201 will lose the torque applied to the torsion spring 5 due to stopping the rotation, and the torsion spring 5 will drive the support plate 201 to follow the rotation. The plate 201 rotates in the opposite direction. When the support plate 201 rotates in the opposite direction, the torsion of the torsion spring 5 will hit the prompt plate 11. After the prompt plate 11 is hit, it will drive the clamping block 9 to flip downward, and the fixing rod 12 will pull the prompt plate 11 through the tension spring 24 to prevent the prompt plate 11 from falling off. Finally, the user observes the prompt plate 11. When the prompt plate 11 flips, it indicates that the belt has slipped. The user resets the prompt plate 11 and marks and collects the conveyor belt that has slipped.

[0049] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
