[0035] An anchoring unit passes through the connecting unit to fix the connecting unit on the rock and soil slope.

[0036] Through the above technical solution, the rock slope is fixed and protected by the connecting frame 1, the fixing block 2 and the anchoring unit.

[0037] In this embodiment, the connecting unit includes a first connecting member 5 and a second connecting member 6; the first connecting member 5 is connected to one end of the fixed block 2; the second connecting member 6 is connected to the other end of the fixed block 2; wherein, in two laterally adjacent fixed blocks 2, the first connecting member 5 of one fixed block 2 is connected to the second connecting member 6 of the other fixed block 2 through an anchoring unit.

[0038] In this embodiment, a first opening 7 is provided on the first connecting member 5; a plurality of second openings 8 are provided on the second connecting member 6; the first connecting member 5 and the second connecting member 6 are hollow inside; the first connecting member 5 is sleeved on the outside of the second connecting member 6 so that the first opening 7 and the second opening 8 are arranged correspondingly; the anchoring unit passes through the first opening 7 and the second opening 8 in sequence and is inserted into the rock and soil slope to fix the first connecting member 5 and the second connecting member 6.

[0039] Through the above technical solution, each fixed block 2 is connected with a first connecting member 5 and a second connecting member 6. In two laterally adjacent fixed blocks 2, the first connecting member 5 in one fixed block 2 is sleeved on the outside of the second connecting member 6 in the other fixed block 2; the corresponding positions of the first opening 7 and the second opening 8 are determined according to the sleeve length of the first connecting member 5. The longer the sleeve length is, the shorter the combined length of the first connecting member 5 and the second connecting member 6 is, so that the distance between two laterally adjacent fixed blocks 2 is shorter, thereby adjusting the coverage area of ​​multiple fixed blocks 2 on the rock slope according to actual needs.

[0040] In this embodiment, the anchoring unit includes an anchoring shell 9, a moving block 10 and a plurality of fixing hooks 11; the anchoring shell 9 is inserted into the rock slope after passing through the first opening 7 and the second opening 8 in sequence; the moving block 10 is slidably arranged in the anchoring shell 9; the end of the moving block 10 is connected to a pressure rod 12; the pressure rod 12 extends to the outside of the anchoring shell 9; the fixing hook 11 is connected to an end of the moving block 10 away from the pressure rod 12; a plurality of third openings are arranged at the bottom of the anchoring shell 9; a plurality of fixing hooks 11 are arranged in the plurality of third openings in a one-to-one correspondence and slide up and down in the third openings.

[0041] The fixing hook 11 is in an arc shape, the third opening is in an arc shape, and the fixing hook 11 and the third opening have the same curvature, so that the fixing hook 11 can move up and down in the third opening.

[0043] The bottom of the anchor shell 9 is sharpened to enable the anchor shell 9 to be inserted into the rock slope more quickly and conveniently.

[0044] Through the above technical solution, the fixed block 2 is fixed on the rock and soil slope through the anchor shell 9; by knocking the compression rod 13, the compression rod 12 pushes the movable block 10 to move downward (downward movement refers to movement toward the inside of the rock and soil slope), and the fixed hook 11 moves downward in the third opening to the rock and soil slope, fixing the anchor shell 9 in the rock and soil slope.

[0045] In this embodiment, two first grooves 14 are provided on one end of the moving block 10 close to the pressure rod 12; the two first grooves 14 are symmetrically arranged about the central axis; an elastic block 16 is arranged in the first groove 14; the elastic block 16 and the first groove 14 are connected by a first spring 17 so that the elastic block 16 can be laterally extended and retracted in the first groove 14.

[0048] Through the above technical solution, the moving block 10 moves downward until the first groove 14 moves to align with the second groove 15, so that the elastic block 16 in the first groove 14 enters the second groove 15 under the action of the first spring 17, and the length of the elastic block 16 is longer than the depth of the second groove 15, so that a part of the elastic block 16 is located in the second groove 15, and the rest of the elastic block 16 is located in the first groove 14, thereby limiting the movement of the moving block 10 in the anchoring shell 9.

[0049] In this embodiment, a second spring 18 is further included; the second spring 18 is arranged at the bottom of the anchoring housing 9; one end of the second spring 18 is connected to the moving block 10, and the other end is connected to the fixing hook 11.

[0050] Through the above technical solution, during the downward movement of the moving block 10, the second spring 18 is compressed, and under the action of the second spring 18, the fixing hook 11 moves downward into the rock slope to complete the fixation of the anchor shell 9; the elastic block 16 enters the second groove 15 to limit the moving block 10.
