[0026] like Figure 1 As shown, the clamping mechanism 1 includes a mounting platform 101 , and a controller 102 is mounted on the front surface of the mounting platform 101 , so that the controller 102 can determine whether to start the electric push rod 106 .

[0027] like Figure 1-Figure 3 As shown, two L-shaped blocks 103 are placed on the top of the mounting platform 101. A slide groove 104 is provided on the top of each L-shaped block 103. The slide 105 can move stably with the cooperation of the slide groove 104, the L-shaped block 103 and the electric push rod 106.

[0028] like Figures 1-4 As shown, a slide 105 is slidably connected to the inside of each slide groove 104, and an electric push rod 106 is installed on the top of each L-shaped block 103, so that the slide 105 can be driven to move inside the slide groove 104 under the action of the activated electric push rod 106.

[0029] like Figures 1-4 As shown, the telescopic end of each electric push rod 106 is movably sleeved inside each slide groove 104, and one end of the telescopic end of each electric push rod 106 is installed on the top of each slide plate 105.
