Because the teeth of the transmission shaft 22 (square steel) have been embedded in the teeth of the locking block 121, and the locking block 121 and the base 11 cannot be opened due to the tapered surface, the handle is firmly fixed. When dismantling, through the tool hole 111 (removal port 123), the two movably connected locking blocks 121 are moved downward, because of the conical principle, the locking blocks 121 can be movably separated, so that the transmission shaft 22 (square steel) The tooth position is separated from the upper tooth position of the locking block 121 . This makes it easy to pull out the handle.

Due to the above structure, the locking block 121 will rotate synchronously with the handle, and due to the return spring, the problem of the virtual position shaking of the handle can be fully solved. Compensation, realizes the virtual position compensation function after wear, the product has a long service life, the use effect is better, and the user experience is good. .

The above descriptions are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements or improvements made within the spirit and principles of the present invention shall be included in the protection of the present invention. within the range.
