[0053] Furthermore, the adjustment fixing seat 25 in this implementation includes: two fixed limiting plates 20 arranged opposite to each other up and down, an adjustment stud 21, and a locking nut 22.

The device utilizes a combination of a double slider and a four-bar mechanism in a lateral clamping mechanism 1 and a longitudinal drive assembly 2, and cleverly utilizes a drive to achieve the purpose of clamping the device in a lateral and longitudinal bidirectional motion. At the same time, according to the clamping position and retreat position required by the device, the universal rotatability of the universal rotating head 23 of the existing device and the four-bar quick return characteristics of the double ball head long rod 26 are utilized to determine the required starting angle θ, determine the optimal stroke speed ratio variation coefficient, and control the separation and clamping efficiency of the device. By adjusting the double slider at the end of the limit seat 24, the device can be clamped. The degree of freedom of the ball head long rod 26 and the degree of freedom of the double ball head long rod 26 at the end of the adjustment fixing seat 25 solve the problem of movement jamming that may occur in the lateral supporting mechanism 1 during the movement of the conventional four-bar mechanism.
