Figures 3 to 6 The transmission mechanism 5 includes a support plate 501, two sliding grooves 502 are arranged on the top side of the support plate 501, a toothed sliding plate 503 is slidably arranged on the top side of the support plate 501, a transverse tooth 507 is fixedly arranged on one side of the toothed sliding plate 503, a first supporting bent rod 504 is fixedly arranged on the rear side of the top side of the toothed sliding plate 503, a first fixing bolt 505 is arranged on the top side of the first supporting bent rod 504, a first sliding block 506 is slidably arranged on the inner side of the first supporting bent rod 504, the sliding grooves 502, the toothed sliding plates 503 and the transverse teeth 507 are all two, and the first supporting bent rod 504 and the second supporting bent rod 508 on the top sides of the two toothed sliding plates 503 are relatively moved by the transverse teeth 507 through the transmission gear 511.
[0027] In this embodiment, the slide groove 502, the toothed sliding plate 503 and the transverse teeth 507 are symmetrically arranged on the top side of the support plate 501, and are arranged on both sides of the transmission gear 511. At the same time, the two transverse teeth 507 are engaged with the transmission gear 511, so that the first support bent rod 504 and the second support bent rod 508 are relatively transversely moved when they move transversely. The fixed disk 601 is clamped and fixed by the first sliding block 506 and the second sliding block 510, so that the fixed disk 601 fixes the adjusting nut 4 to prevent the adjusting nut 4 from loosening and ensure its stability.
[0028] Furthermore, a second supporting bent rod 508 is fixedly provided on the top side of one of the two toothed sliding plates 503, a second fixing bolt 509 is provided on the top side of the second supporting bent rod 508, a second sliding block 510 is slidably provided on the inner side of the second supporting bent rod 508, a hole is penetrated through the second sliding block 510, and the hole has a built-in thread, which is engaged with the second fixing bolt 509.

[0031] With the above structure, when the clearance of the adjustment arm is adjusted, the adjustment nut 4 drives the fixed disc 601 and the gear disc 603 in the control mechanism 6 to rotate, and then the gear disc 603 drives the toothed sliding plate 503 in the slide groove 502 to move, and the toothed sliding plate 503 moves with the transverse teeth 507 and the first supporting bent rod 504 to move inwardly. When the first supporting bent rod 504 moves close to the gear disc 603, the first sliding block 506 slides into the slot 602 provided in the fixed disc 601, and the first sliding block 506 is engaged with the first supporting bent rod 504. The damping between the movable block 506 and the slot 602 enables the fixed disc 601 to be fixed by the first sliding block 506. The second sliding block 510 drives the transmission gear 511 through the symmetrical transverse teeth 507. The toothed sliding plate 503 in one of the slide slots 502 moves the second supporting bent rod 508 on the top side, and moves the second supporting bent rod 508 and the second sliding block 510 toward the fixed disc 601.
