Through the cooperation of the above-mentioned fixing mechanism, the application scope of the detection equipment is improved; when the explosion-proof tire is fixed, it needs to be tested. First, the staff needs to add water to the water tank 2, and then start the cylinder 27. The insertion rod 28 drives the needle 29 to move downward, and the needle 29 is inserted into the explosion-proof tire. Then the second servo motor 23 is started, and the threaded rod 22 rotates to drive the moving plate 24 to move downward.
