[0030] Specifically, the first tooth plate 203 and the second tooth plate 205 match in shape and size, and the first tooth plate 203 and the second tooth plate 205 are symmetrically arranged with the mid-perpendicular line of the gear 204 as the symmetry axis.

[0031] Through the above technical solution, while the first tooth plate 203 is driven to perform horizontal movement, the second tooth plate 205 will perform horizontal movement in the opposite direction to the first tooth plate 203 under the drive of the gear 204 .

[0032] Specifically, the first tooth plate 203 and the second tooth plate 205 form a movable structure through the limiting rod and the limiting groove 206 , and one end of the limiting rod passes through the limiting groove 206 .

[0033] Through the above technical solution, the limiting rod slides in the limiting groove 206, so that the first tooth plate 203 and the second tooth plate 205 will not deviate during the horizontal movement.
