The side wall of the mounting block 9 is penetrated by a screw 10, and the side wall of the screw 10 is provided with a clamping plate 8 and a first nut, and the side wall of the screw 10 is provided with a second gasket. The side wall of the mounting block 9 is provided with a connecting disk 11, and the side wall of the connecting disk 11 is provided with a plurality of second bolts. Two limit plates 17 are provided on both side walls of the mounting seat 5, and two limit grooves are provided on the upper end of the mounting plate 4. A plurality of third bolts are provided on the upper end of the limit plate 17, and the side wall of the third bolt is provided with a second nut, and the side wall of the third bolt is provided with a third gasket.

[0022] The adjusting mechanism includes a placement plate arranged at the output end of the hydraulic cylinder 7, a fixing frame 14 and a threaded rod 15 are provided at the upper end of the placement plate, a lifting plate 13 is provided on the side wall of the threaded rod 15, and the upper end of the lifting plate 13 is fixedly connected to the lower end of the mounting frame 12.

[0023] In the present invention, the cross section of the lifting plate 13 is rectangular, which can prevent the lifting plate 13 from only moving vertically when the threaded rod 15 rotates. The side wall of the threaded rod 15 is fixedly connected to a hand wheel 16.

[0024] In the present invention, a plurality of mounting holes are provided on the side wall of the connecting plate 11, and the plurality of mounting holes are arranged at equal intervals. A plurality of positioning holes are provided on the upper end of the mounting plate 6, and the plurality of positioning holes are arranged at equal intervals.
