By providing the slide groove 5, the movement of the slide block 4 is guided. A bi-directional screw 6 is movably connected inside the slide block 4. The outer side of the bi-directional screw 6 is threadedly connected with a top plate 7. The top plate 7 and the slide base 1 are slidably connected. A spring 8 is arranged on the outer side of the bi-directional screw 6. One end of the spring 8 is fixedly connected to the slide block 4, and the other end of the spring 8 is fixedly connected to the top plate 7. By providing the spring 8, the slide block 4 is elastically pressed tightly. A knob 9 is fixedly connected to the outer side of the bi-directional screw 6. A limit plate 10 is fixedly connected to the upper end of the slide base 1. The limit plate 10 and the bi-directional screw 6 are rotatably connected. The limit plate 10 contacts the knob 9. By providing the limit plate 10, the knob 9 is limited.

[0020] Please refer to Figure 1 , Figure 4 , the support mechanism 3 includes a side plate 31. The side plate 31 is hinged to the upper end edge of the slide plate 2. A connecting rod 32 is hinged to the surface of the side plate 31. The lower end of the connecting rod 32 is hinged to a slide bar 33. The slide bar 33 and the slide base 1 are slidably connected. A dovetail block is fixedly connected to the lower end of the slide bar 33. A dovetail groove 34 is opened at the upper end of the slide base 1. The dovetail groove 34 and the dovetail block are slidably connected. By providing the cooperation of the dovetail block and the dovetail groove 34, the movement of the slide bar 33 is guided. A support plate 35 is welded to the upper end of the slide plate 2. A screw 36 is installed inside the support plate 35 through a bearing. The screw 36 and the slide bar 33 are threadedly connected.

[0021] The specific implementation process of the present utility model is as follows: During use, place the device inside the groove. The sliding seat 1 contacts the bottom of the groove. Manually rotate the bidirectional screw 6. The bidirectional screw 6 rotates and engages in a threaded motion with the top plate 7, causing the top plate 7 to move away from the knob 9. The movement of the top plate 7 compresses the spring 8. Through the elastic action of the spring 8 on the slider 4, the slider 4 drives the sliding plate 2 to move, causing the sliding plate 2 to elastically press the support mechanism 3 against the side wall of the groove. The device can support grooves with different widths. And through the elastic action of the spring 8 on the slider 4, it is avoided that the support mechanism 3 exerts too much pressure on the groove wall at the current position, resulting in the soil on the side walls of the surrounding grooves falling off. Adjust the angle of the side plate 31 according to the inclination angle of the inner wall of the groove. Manually rotate the screw 36. The screw 36 rotates and engages in a threaded motion with the slide bar 33, causing the slide bar 33 to drive the connecting rod 32 to deflect, and then causing the angle of the side plate 31 to change, enabling the device to support groove walls with different angles.
