[0028] As shown in Figure 3As shown, the supporting mechanism 4 comprises two groups of telescopic rods 401 symmetrically fixedly installed on the inner bottom wall of the bridge body 1, a support plate 402 fixedly connected at the top end of the telescopic rods 401, a spring I 403 sleeved on the surface of the telescopic rods 401 and connected with the bridge body 1 and the support plate 402 at two ends respectively, and a plurality of cable seats 404 fixedly installed on the top of the support plate 402, wherein the telescopic rod 401 is composed of a sleeve and a rod movably inserted into the sleeve;

[0029] As shown in Figure 3 , the pressing mechanism 501 further comprises a fixed shell 5011 fixedly installed on the inner bottom wall of the bridge body 1 and located at one side of the support plate 402, a hand screw bolt 5013 threadedly penetrating one side surface of the fixed shell 5011, and a fixed band 5012 inserted into the fixed shell 5011, one end of the hand screw bolt 5013 abutting against the fixed band 5012, wherein the fixed band 5012 is made of rubber material and has a plurality of protrusions corresponding to the cable seats 404 integrally formed on the inner surface thereof;

[0030] As shown in Figure 4 , the locking mechanism 502 comprises a plurality of trapezoidal limiting blocks 5021 fixedly installed on the outer surface of the fixed band 5012, an adjusting block 5022 fixedly installed on the inner bottom wall of the bridge body 1 and located at the other side of the support plate 402, a movable rod 5023 slidingly penetrating the top of the adjusting block 5022, a spring II 5024 sleeved on the surface of the movable rod 5023, and a locking block 5025 fixedly connected at the bottom end of the movable rod 5023 and matched with the limiting blocks 5021;

[0031] The adjusting block 5022 is provided with a through slot for the fixed band 5012 to pass through, the movable rod 5023 has a T-shaped cross section, the spring II 5024 has two ends connected with the adjusting block 5022 and one end of the movable rod 5023 respectively, and the locking block 5025 has a T shape and is clamped between two adjacent limiting blocks 5021;

[0032] Working principle:

[0033] Firstly, the cable is placed in the cable seat 404 in sequence, then one end of the fixed band 5012 is inserted into the fixed shell 5011 and the hand screw bolt 5013 is screwed to fix the fixed band 5012, then the movable rod 5023 is pulled up to drive the locking block 5025 to move upwards, so that the spring II 5024 is stretched, and the other end of the fixed band 5012 is passed around the cable and through the through slot on the adjusting block 5022, the movable rod 5023 is loosened to drive the movable rod 5023 to reset through the spring II 5024, so that the locking block 5025 moves downwards and cooperates with the limiting blocks 5021 to pre-install the fixed band 5012;

[0034] Secondly, pull the free end of the fixing belt 5012, so that the locking block 5025 is pressed by the limiting block 5021, and the locking block 5025 is guided to move up by the inclined surface of the limiting block 5021, so that the spring 5024 is stretched, so that the fixing belt 5012 is tightened, and the convex block on the inner wall of the fixing belt 5012 is pressed to position the cable on the cable seat 404. After adjustment, the spring 5024 drives the movable rod 5023 to reset again, so that the locking block 5025 is clamped and fixed to the limiting block 5021, and the supporting plate 402 is forced to move downward, compressing the telescopic rod 401 and the spring 401, and buffering through the spring 401, preventing the fixing belt 5012 from being too tight to damage the cable. Conversely, when the tightening force of the fixing belt 5012 is weakened, the movable rod 5023 moves upward to separate the limiting block 5021 and the locking block 5025, so that the length of the fixing belt 5012 can be adjusted to achieve the effect of adjusting the tightening force, which is convenient for adjusting the tightening force according to different types of cables.

[0035] Finally, cover the cover plate 2 on the bridge body 1, so that the positioning block 304 is clamped with the limiting column 305, so as to position the cover plate 2. At this time, the buckle 302 is located above the clamping block 303. Press the cover plate 2 downward, so that the elastic sheet 301 is deformed under stress to drive the buckle 302 to move away from the clamping block 303. In order to move the buckle 302 to the lower side of the clamping block 303, then drive the buckle 302 to reset by the elastic sheet 301 and clamp the clamping block 303. When disassembling the cover plate 2, bend the elastic sheet 301 outward to separate the buckle 302 from the clamping block 303, and then disassemble it. Therefore, the cover plate 2 is conveniently and quickly installed and disassembled.

[0036] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
