[0018] The movable clamping assembly 23 includes a movable clamping block 231 , a fixing frame 232 is fixedly mounted on the movable clamping block 231 , an auxiliary clamping block 233 is slidably arranged between the fixing frames 232 , and the auxiliary clamping block 233 is driven by a manual screw drive assembly 24 ; A slider 27 is slidably provided in the L-shaped support seat 22 , and a screw assembly 26 is screwed into the slider 27 . A pressing assembly is provided on one side of the screw assembly 26 , and one side of the pressing assembly is magnetically connected to the auxiliary clamping block 233 .

[0019] In addition, the screw assembly 26 includes a screw portion, with a handle ring and a limit ring installed at both ends of the screw portion respectively, and a threaded hole is opened through the slider 27 at the screw portion.

[0021] At the same time, the cross section of the auxiliary clamping block 233 is inverted L-shaped, and a magnetic groove 234 is opened on one side of the auxiliary clamping block 233 at the magnetic ring, and the inner wall of the magnetic groove 234 is provided with a magnetic material that is attracted to the magnetic ring.

[0022] Furthermore, slide rails are symmetrically provided on the top of the base 21 and on both sides of the support platform 29 , and the movable clamping block 231 is slidably connected to the slide rails.

[0023] Furthermore, a cavity is defined in the L-shaped support seat 22 , in which an electric telescopic rod 28 is placed. The top extending end of the electric telescopic rod 28 is connected to a connecting block, one end of which is connected to the movable clamping block 231 .
