[0025] As an embodiment of the utility model, a cylinder 15 is fixedly connected to the left side of the inner cavity of the mounting frame 2, and the output end of the cylinder 15 is fixedly connected to the left side of the adjusting plate 7.

[0026] As an embodiment of the utility model, a slide groove 16 is provided at the front and rear ends of the bottom of the inner cavity of the installation frame 2, and a slider 17 is slidably connected to the inner cavity of the slide groove 16.
