[0036] Example 1

[0037] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a wire fixing mechanism, specifically including,

[0038] Support assembly 100 includes pulley 101 and fixing member 102, with pulley 101 located below fixing member 102;

[0039] Fastening assembly 200 includes a main pressure member 201 and a secondary pressure member 202. The secondary pressure member 202 is located above the main pressure member 201, and the main pressure member 201 is located above the pulley member 101.

[0041] It should be noted that the pulley 101a and the pulley seat 101b are slidably connected; there are two support plates 101b-2, located on both sides of the pulley 101a; and the fixed seat 101b-3 is fixed on one support plate 101b-2.

[0042] In this embodiment, pulley 101a is used to support the wire and allow the wire to slide on it; support plate 101b-2 is used to support pulley 101a and fixed base 101b-3.

[0043] Preferably, the fastener 102 includes a first clamp 102a, a second clamp 102b, a third clamp 102c, and a fourth clamp 102d. The second clamp 102b is located above the first clamp 102a, the third clamp 102c is located in the second clamp 102b, and the fourth clamp 102d is located on one side of the second clamp 102b. The second clamp 102b includes an insulating sleeve 102b-1 and a pull ring 102b-2, with the pull ring 102b-2 located on one side of the insulating sleeve 102b-1.

[0044] It should be noted that the first clamp 102a is bolted to the fixed base 101b-3; the second clamp 102b is hinged to the first clamp 102a and the third clamp 102c; the third clamp 102c is hinged to the second clamp 102b and the fourth clamp 102d; the fourth clamp 102d is hinged to the third clamp 102c and the first clamp 102a; and the pull ring 102b-2 is welded to the second clamp 102b.

[0046] Example 2

[0047] Reference Figures 1 to 8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0048] Specifically, the main pressing component 201 includes a nut 201a, a washer 201b, and a screw pressing part 201c. The washer 201b is located on one side of the nut 201a, and the screw pressing part 201c is located below the nut 201a. The screw pressing part 201c includes a screw 201c-1, a limiting shell 201c-2, a pressing block 201c-3, and a spring 201c-4. The screw 201c-1 is located above the limiting shell 201c-2, the pressing block 201c-3 is located in the limiting shell 201c-2, and the spring 201c-4 is located above the pressing block 201c-3.

[0049] It should be noted that the gasket 201b has protruding iron plates on both sides; the bottom surface of the pressure block 201c-3 has two rounded edges, which facilitates contact with the wire and does not wear the wire; there are two springs 201c-4, which are symmetrically arranged about the screw 201c-1; the screw 201c-1 is fixed on the limiting shell 201c-2; the pressure block 201c-3 and the limiting shell 201c-2 are slidably connected.

[0050] In this embodiment, nut 201a and washer 201b are used to fix screw 201c-1; pressure block 201c-3 is used to contact the wire, and limiting shell 201c-2 is used to restrict the movement of pressure block 201c-3.

[0051] Furthermore, the limiting shell 201c-2 includes a top plate hole 201c-2a and a pressure rod hole 201c-2b, with the pressure rod hole 201c-2b located below the top plate hole 201c-2a.

[0052] It should be noted that the top plate hole 201c-2a is a square through hole; the pressure rod hole 201c-2b is connected to the top plate hole 201c-2a.

[0053] Preferably, the auxiliary pressure member 202 includes a top plate 202a, a pressure bar 202b, a connecting plate 202c, and a pressure column 202d. The pressure bar 202b is located below the top plate 202a, the connecting plate 202c is located on one side of the top plate 202a, and the pressure column 202d is located on the connecting plate 202c.

[0054] It should be noted that the pressure rod 202b is fixed on the pressure block 201c-3; the pressure rod 202b is slidably connected to the pressure rod hole 201c-2b; the top plate 202a is slidably connected to the top plate hole 201c-2a; the top plate 202a and the connecting plate 202c are hinged; and the pressure column 202d is fixed on the connecting plate 202c.

[0055] In this embodiment, after the operator places the wire on the pulley 101a, the nut 201a and washer 201b need to be adjusted so that the screw pressing part 201c moves downward as a whole. When the screw pressing part 201c moves downward as a whole, the pressure block 201c-3 will press on the wire and compress the spring 201c-4, applying a certain force to the wire. At the same time, the pressure rod 202b also moves upward, causing the top plate 202a to move upward at the same time. At this time, the part of the connecting plate 202c near the limiting shell 201c-2 will press on the limiting shell 201c-2, causing the connecting plate 202c to rotate around the hinge point with the top plate 202a, thereby causing the pressure column 202d to press on the wire.

[0056] It should be noted that under the pressure of the pressure block 201c-3 and the pressure column 202d, the wire will conform to the pulley 101a in a "convex" shape, increasing the contact area between the wire and the pulley 101a and making the wire more firmly fixed; the rounded shape of the pressure block 201c-3 and the round surface of the pressure column 202d can still make the wire slide smoothly under a certain pressure.
