A mounting hole 101 is opened on the top of the hanging rod 1; according to the angle of the rock surface in the mine, the hanging rod 1 is fixed on the rock surface by expansion bolts.
[0028] A receiving groove 201 is provided at the bend of the hook body 2, and a plurality of grooves are correspondingly provided on the two opposite side walls of the receiving groove 201. Two groups of symmetrically arranged clamping components 3 for clamping the cable 4 are rotatably connected in the receiving groove 201, and there is a gap between the two groups of clamping components 3.
[0029] In this embodiment, the clamping assembly 3 includes: a rotating shaft 302, which is located at the intersection of the side wall and the bottom wall of the accommodating groove 201, and both ends of the rotating shaft 302 are rotatably connected to two opposite grooves through bearings.
[0030] The first pressing rod 301 has one end connected to the rotating shaft 302 , and the other end of the first pressing rod 301 extends in the receiving groove 201 in a direction away from the bottom wall of the receiving groove 201 by a predetermined distance.
[0031] The second pressure rod 303 has one end connected to the rotating shaft 302, and the other end of the second pressure rod 303 horizontally extends to a predetermined distance outside the receiving groove 201.
