[0029] The position of the adjusting block 8 can be adjusted accurately through the meshing transmission of the worm 7 and the worm wheel 6, and the self-locking effect is guaranteed, so that the stability of the bottom cylinder 12 is ensured when the product is adsorbed.

[0030] As shown in Figures 1-5 In order to improve the adsorption effect of the product, the adsorption assembly comprises a bottom cylinder 12, an electric push rod 13, a piston 14, a suction cup 15, a partition plate 16, a connecting pipe 17, a spring 18, a sealing ring 19 and an arc block 20. The bottom cylinder 12 is fixedly connected to the bottom of the adjusting block 8, the inside of the bottom cylinder 12 is hollow, and the lower end center of the bottom cylinder 12 is provided with an opening. The electric push rod 13 is fixedly connected to the top inside of the bottom cylinder 12. The piston 14 is fixedly connected to the free end of the electric push rod 13. The suction cup 15 is fixedly connected to the bottom of the bottom cylinder 12 and communicates with the inside of the bottom cylinder 12.
