The cross-section of both the first and second anti-slip protrusions 33 and 34 is triangular. These protrusions increase the friction between the pulley 3 and the rope, preventing slippage when the pulley 3 rotates.

[0024] Example 2 like Figures 5 to 10 As shown, a rope retractor includes a mounting frame 1, two side plates 2, and two pulleys 3. A lifting ring 7 is installed at the tail end of the mounting frame 1 with bolts 6.

[0025] The two side plates 2 are hinged to the mounting frame 1 via a rotating shaft 4. Bearings 8 are installed on the mounting frame 1 and the side plates 2 respectively, and the rotating shaft 4 is fitted in the inner ring of the bearings 8.

[0026] The rear end of the mounting bracket 1 is also provided with an L-shaped slot 11, and the rear end of the side plate 2 is plugged into the L-shaped slot 11; the rear end of the mounting bracket 1 is provided with a mounting groove 12, in which a compression spring 121 and a pin 122 are installed; a screw 13 is screwed onto one side of the mounting bracket 1 located in the mounting groove 12; a strip-shaped guide groove 1221 parallel to the central axis of the pin 122 is provided on one side of the pin 122; the rear end of the screw 13 is inserted into the strip-shaped guide groove 1221; the rear end of the side plate 2 is provided with a pin hole 21, and the pin 122 is plugged into the pin hole 21.

[0027] Two pulleys 3 are respectively installed on the rotating shaft 4 between the mounting bracket 1 and the two side plates 2, and the pulleys 3 and the rotating shaft 4 are fixed relative to each other so that the pulleys 3 rotate together with the rotating shaft 4. Specifically, the pulleys 3 and the rotating shaft 4 are connected by a flat key. One part of the flat key is stuck in the flat key receiving groove set on the side of the rotating shaft 4, and the other part of the flat key is stuck in the flat key slot on the inside of the pulley 3.

[0028] The rotating shaft 4 is provided with a connecting hole 41. When winding the rope, a connecting wrench is installed on the pistol drill, and the connecting wrench is inserted into the connecting hole 41. The working of the pistol drill drives the connecting wrench to rotate, thereby driving the rotating shaft 4 and the pulley 3 to rotate.

[0029] The rotating shaft 4 includes two hollow shafts 42 and one solid shaft 43. One end of the hollow shaft 42 is riveted to the solid shaft 43. The other end of the hollow shaft 42 is provided with a first flange 421 protruding outward. One end of the solid shaft 43 is provided with a second flange 431 protruding outward.

The first and second anti-slip protrusions 33 and 34 are arranged in a one-to-one correspondence and mirror image symmetrical arrangement, and are spirally radial. The cross-section of both the first and second anti-slip protrusions 33 and 34 is triangular. These protrusions increase the friction between the pulley 3 and the rope, preventing slippage when the pulley 3 rotates.

[0032] When it is necessary to install the rope, press the pin 122 into the mounting groove 12, so that the pin 122 is pulled out from the pin hole 21. Rotate the side plate 2 to pull it out from the L-shaped slot 11 until the side plate 2 is rotated 90°, and the rope is wrapped from one side of the pulley 3 to the other side.
