[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0019] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "periphery", etc. indicating the orientation or position relationship are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present utility model.

[0020] Please refer to Figure 1 and 3 As shown, the present utility model is an unstable slope protection and support device. When the protection and support device is in use, first, a slope top surface 101 at the top and an inclined slope surface 102 are manually formed at the slope position. Then, a folded fixing plate 1 is fixed at the joint of the slope top surface 101 and the slope surface 102 by using a first anchor rod 2 and a second anchor rod 3. Then, a rolled protection net 100 is connected to one end of the folded fixing plate 1, and one end of the protection net 100 is controlled to be connected to the folded fixing plate 1. The rolled protection net 100 is controlled to roll down along the slope surface 102, and at this time, the protection net 100 is controlled to cover the slope surface 102. Then, a plurality of fixing members 4 for fixing the protection net 100 on the slope surface 102 are arranged at equal intervals along the slope surface 102 direction, and then the laying work of the protection net 100 is completed through the above steps.

[0021] In the above, as Figure 2 , when the protection net 100 is rolled down along the slope, at this time, the folded fixing plate 1 is subjected to a large force from the protection net 100, and in this stage, it is easy for the folded fixing plate 1 to be separated from the joint of the slope top surface 101 and the slope surface 102. In order to improve the stability of fixing the folded fixing plate 1 at the joint of the slope top surface 101 and the slope surface 102 by using the first anchor rod 2 and the second anchor rod 3, the first anchor rod 2 is perpendicular to the slope surface 102, and the second anchor rod 3 is perpendicular to the slope top surface 101; an opening 233 is provided at the end of the first anchor rod 2, and the end of the second anchor rod 3 penetrates through the opening 233. Then, in the above, the second anchor rod 3 and the first anchor rod 2 are used in cooperation to complete the fixation and improve the firmness.

[0022] Specifically, as Figure 2-4, the first anchor rod 2 includes an anchor rod body 20. A channel 21 is provided at the end of the anchor rod body 20 along its axial direction. A convex ring 22 is provided on the inner side wall of the middle part of the channel 21. An active rod 23 is movably arranged in the channel 21 on one side of the convex ring 22. An opening 233 is formed in the active rod 23. One end of the active rod 23 is provided with a rectangular concave hole 232, and the other end is provided with a conical drill rod 231. Thus, when in use, first drive a part of the second anchor rod 3 into the slope top surface 101, and then control the whole anchor rod body 20 to be driven into the slope surface 102. Use a top rod inserted into the channel 21 and with its end passing through the opening 233 and abutting against the active rod 23. Knock the top rod to drive the active rod 23 to continue to be driven into the soil along the direction perpendicular to the slope surface 102. At the same time, control the rectangular block provided at the end of the top rod to be inserted into the rectangular concave hole 232, control the top rod to drive the active rod 23 to rotate in the channel 21, control the axial direction of the opening 233 to be parallel to the axial direction of the second anchor rod 3 at this time, and then continue to control the second anchor rod 3 to be driven into the soil. Then the end of the second anchor rod 3 passes through the opening 233.

[0023] In order to improve the fixing effect on the protection net 100 and keep the protection net 100 as close as possible to the slope surface 102, as Figure 5 , the fixing member 4 includes a T-shaped drill rod 40 and a pressing frame 41. A "cross" frame 42 is connected to the inner wall of the pressing frame 41. Through holes are formed in the "cross" frame 42. The T-shaped drill rod 40 passes through the through holes, and a conical rod 43 is provided on one side of the pressing frame 41.
