[0023] Sleeve 13 is rotatable and is fitted inside movable groove 11;

[0024] Specifically, such as Figure 1 and Figure 4 As shown, when the drive motor 7 is turned on, the connecting shaft 10 is driven to rotate. When the connecting shaft 10 rotates, it can drive the main gear 9 to rotate. When the main gear 9 rotates, it can drive the secondary gear 12 to rotate. At this time, the limit plate 15 can rotate on the top of the base 1, and the sleeve 13 rotates in the movable groove 11, which facilitates the rotation and automatic reset of the internally clamped and fixed shaft.

[0025] An interface 3 is provided on the right side of the top shell 2, and a hinge seat 4 is fixedly connected to the right side of the top shell 2. A dust cover 5 is movably hinged between the hinge seats 4.
