Vertical anchoring cylinders 8 are provided on both the upper and lower sides of the side wall of the frame 5 where the rectangular frames 3 are located. One ends of the two anchoring cylinders 8 close to each other are rotatably connected to the side wall of the frame 5 through a rotating shaft 2. The end of the piston rod of the upper anchoring cylinder 8 is provided with an upper foot plate 6 through an extension mechanism, and the end of the piston rod of the lower anchoring cylinder 8 is fixedly provided with a lower foot plate 1. A linkage mechanism capable of simultaneously driving the two anchoring cylinders 8 to rotate is provided inside the rectangular frame 3.

[0022] The linkage mechanism includes a lead screw 10. The lead screw 10 is arranged inside the rectangular frame 3. Both ends of the lead screw 10 are rotatably connected to the inner side wall of the rectangular frame 3 through rolling bearings. A motor 4 is fixedly provided on the outer side wall of the rectangular frame 3. The output end of the motor 4 is fixedly connected to one end of the lead screw 10. An internal thread ring 11 is threadedly connected to the rod wall of the lead screw 10. Connecting rods 9 are hinged on both the upper and lower sides of the internal thread ring 11.
