[0017] The left and right ends of the upper and lower movable support plates 3 are connected with oblique support plates 6, which can also be rectangular parallelepiped plates. The oblique support plates 6 are parallel to the slope protection 2, that is, the inclination angles of the oblique support plates 6 and the slope protection 2 are consistent. A groove A7 is provided on the upper surface of the oblique support plates 6 at the left and right ends, and a lead screw A8 is provided in the groove A7. The lead screw A8 is also parallel to the slope protection 2. The upper end of the lead screw A8 is connected to the rotating shaft of the motor A9 through a coupling, and the motor A9 is fixed on the inner wall of the upper end of the groove A7. The lower end of the lead screw A8 is fixed to the inner wall of the lower end of the groove A7 through a bearing, and the lead screw A8 can rotate in the bearing. A nut A10 is provided on the lead screw A8, and the rotation of the motor A9 drives the nut A10 to move along the lead screw A8. A horizontal support plate 11 is fixed between the nut A10 at the left and right ends, and the horizontal support plate 11 is located above the oblique support plate 6 and is perpendicular to the oblique support plate 6. A groove B12 is provided on the lower surface of the horizontal support plate 11, and the groove B12 is along the length direction of the horizontal support plate 11. A screw B13 is provided in the groove B12, and the screw B13 is perpendicular to the screw A8, wherein one end of the screw B13 is connected to the rotating shaft of the motor B14 through a coupling, and the motor B14 is fixed on the inner wall of one end of the groove B12, and the other end of the screw B13 is fixed on the inner wall of the other end of the groove B12 through a bearing, and the screw B13 can rotate in the bearing.
