Through the external processing equipment, the detected data is displayed and processed on the external display screen. The telescopic rod 11 and the displacement sensor 10 are arranged on three sides of the L-shaped plate 1. Therefore, the separate operation of each telescopic rod 11 will cause the three displacement sensors 10 to detect the front and back, left and right, and up and down tightness of the teeth respectively, and the detection effect is better and faster.

[0026] Example 2, as Figure 1-Figure 5As shown, the driving structure 3 includes a screw 301 arranged in the L-shaped plate 1, and a moving block 302 is threadedly connected on the outer wall of the screw 301. The bottom end of the moving block 302 passes through the L-shaped plate 1 and is fixed to the clamping plate 2. Connecting blocks 303 are fixed at both ends of the moving block 302. The two connecting blocks 303 are slidably connected with limiting columns 304. A connecting column 5 is fixed at one end of the screw 301, and a damping ring 6 is fixed on the outer wall of the connecting column 5.

After fixation, the operation of the telescopic rod 11 drives the impact block 12 to continuously impact the L-shaped plate 1. When the tooth is loose, the L-shaped plate 1 will shake, which is detected by the displacement sensor 10 and processed by the external The device can display and process the detected data on an external display screen, and is arranged on three sides of the L-shaped plate 1 through the telescopic rod 11 and the displacement sensor 10. Therefore, the separate operation of each telescopic rod 11 will cause the three displacement sensors 10 to detect the front and back, left and right, and up and down tightness of the teeth respectively. During the detection, the first detection method is the looseness of the teeth in all directions. The first degree of tooth looseness is within 1mm; the second degree of tooth looseness is between 1 and 2mm, and the third degree of tooth looseness exceeds 2mm. The second detection method is that if the tightness of the teeth in two directions is within 1mm, it is second degree looseness; if the tightness of the teeth in two directions is beyond 1mm, it is third degree looseness.
