The other side of the fixing plate 2 is rotatably connected to a U-shaped frame 4 through a pin. A hanging rod 5 is fixedly connected to the top of the U-shaped frame 4. One side of the hanging rod 5 is clamped with the inner wall of the arc-shaped clamping rod 3. A positioning frame 6 is fixedly installed in the inner cavity of the U-shaped frame 4. A reset mechanism 7 is arranged in the inner cavity of the positioning frame 6. A positioning mechanism 8 is arranged at the bottom of the fixing plate 2;

[0029] The reset mechanism 7 includes sliding rods 701. The number of sliding rods 701 is three. The three sliding rods 701 are all fixedly installed in the inner cavity of the positioning frame 6. A sliding sleeve 702 is slidably connected to the surface of the sliding rod 701. A first spring 703 is arranged at the bottom of the sliding sleeve 702. The first spring 703 is sleeved on the surface of the sliding rod 701. One end of the first spring 703 is fixedly connected to the surface of the sliding sleeve 702. The other end of the first spring 703 is fixedly connected to the inner wall of the positioning frame 6. A limiting frame 704 is fixedly connected to one side of the sliding sleeve 702. A support rod 705 is rotatably connected to the inner cavity of the limiting frame 704 through a rotating shaft. The other end of the support rod 705 is rotatably connected to a fixing frame 706 through a rotating shaft. One side of the fixing frame 706 is fixedly connected to the inner wall of the U-shaped frame 4; By setting the reset mechanism 7, when the U-shaped frame 4 is pressed, the U-shaped frame 4 deforms, and then the hanging rod 5 can be removed from the inner cavity of the arc-shaped clamping rod 3, which is beneficial for the staff to maintain. After the maintenance is completed, the staff presses one side of the U-shaped frame 4 to make the U-shaped frame 4 deform. At this time, after moving one end of the U-shaped frame 4 to the bottom of the fixing plate 2, the reset mechanism 7 is used to reset the shape of the U-shaped frame 4, and then the fixing of the U-shaped frame 4 can be completed.

[0030] Referring to Figure 2 、 Figure 3 、 Figure 6 and Figure 7, the positioning mechanism 8 includes a positioning seat 801. The number of positioning seats 801 is four, and the four positioning seats 801 are all fixedly installed at the bottom of the fixing plate 2. The four positioning seats 801 are arranged staggeredly. Two pulling blocks 802 are slidably connected to the inner cavity of the positioning seat 801. One side of the two pulling blocks 802 penetrates into the inner cavity of the positioning seat 801. A clamping block 803 is fixedly connected to one side of the two pulling blocks 802 facing each other. The other side of the clamping block 803 is clamped with an inclined block 804. The number of inclined blocks 804 is two, and a U-shaped block 805 is fixedly connected between the bottoms of the two inclined blocks 804. The top of the U-shaped block 805 contacts the bottom of the positioning seat 801; by setting the positioning mechanism 8, the cable can be positioned, improving the stability of cable use, and after removing the U-shaped block 805, the limit on a single cable can be released, which is conducive to the maintenance by the staff.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , a toughness groove 9 is provided on one side of the U-shaped frame 4. The number of toughness grooves 9 is several; by setting the toughness groove 9, the U-shaped frame 4 has toughness. After pressing the side of the U-shaped frame 4 where the toughness groove 9 is opened, the hanging rod 5 can be separated from the inner cavity of the arc-shaped clamping rod 3, realizing the unfolding of the U-shaped frame 4, which is convenient for the staff to carry out maintenance operations.

[0032] Refer to Figure 3 and Figure 4 , fixed frames 10 are fixedly connected to both sides of the positioning frame 6. The bottom of the fixed frame 10 is fixedly connected to the inner wall of the U-shaped frame 4 by bolts; by setting the fixed frame 10, the positioning frame 6 can be fixed to prevent the positioning frame 6 from shifting during use.

[0033] Refer to Figure 4 and Figure 5 , the limiting frame 704 is arranged on the outer surface of the positioning frame 6, and the side of the limiting frame 704 close to the positioning frame 6 contacts the surface of the positioning frame 6; by setting the limiting frame 704 to cooperate with the positioning frame 6, the stability of the limiting frame 704 during use can be improved, preventing its position from shifting when moving vertically.

[0034] Refer to Figure 6 , positioning blocks 806 are fixedly connected to both sides of the positioning seat 801. The top of the positioning block 806 is fixedly connected to the bottom of the fixing plate 2; by setting the positioning block 806, the positioning seat 801 can be fixed to prevent the positioning seat 801 from falling off during use.

[0035] Refer to Figure 7, a second spring 807 is provided on one side of the clamping block 803. One end of the second spring 807 is fixedly connected to the surface of the clamping block 803, and the other end of the second spring 807 is fixedly connected to the inner wall of the positioning seat 801; by providing the second spring 807, the quick disassembly and assembly of the U-shaped block 805 can be realized, so as to facilitate the maintenance of the cable by the staff.

[0036] Working principle: When in use, the staff pushes one end of the bottom of the U-shaped frame 4 upward and presses the U-shaped frame 4 backward. Since the resilient groove 9 is provided on the surface of the U-shaped frame 4, the U-shaped frame 4 can be deformed and move backward during the pressing process. When the U-shaped frame 4 moves backward, it drives the hanging rod 5 and the fixed frame 706 to move backward. When the fixed frame 706 moves backward, it drives one end of the support rod 705 to move backward. At this time, the other end of the support rod 705 drives the limit frame 704 to move downward. When the limit frame 704 moves downward, it drives the sliding sleeve 702 to squeeze the first spring 703. When the hanging rod 5 moves out of the inner cavity of the arc-shaped clamping rod 3, the U-shaped frame 4 can be opened. Then, the two pulling blocks 802 are pulled backward. When the two pulling blocks 802 move backward, they drive the two clamping blocks 803 to move backward. When the two clamping blocks 803 move backward, they squeeze the second spring 807. When the clamping block 803 is disengaged from the inclined block 804, the U-shaped block 805 can be disassembled. By disassembling the U-shaped block 805, the limit on the cable can be released, which is beneficial for the staff to maintain a single cable. And by installing the U-shaped block 805, the limit on a single cable can be realized, thereby improving the stability of the cable arrangement and use. After the staff finishes the maintenance, the staff presses one side of the U-shaped frame 4 to deform the U-shaped frame 4 and drive the support rod 705 to squeeze the first spring 703. When the U-shaped frame 4 drives the hanging rod 5 to move to the specified position, hold the bottom of the U-shaped frame 4 and release the hand pressing the U-shaped frame 4. At this time, under the reaction force of the first spring 703, the sliding sleeve 702 drives the limit frame 704 to move upward. By pressing the fixed frame 706 through the support rod 705, the reset of the U-shaped frame 4 is realized, and the hanging rod 5 is clamped into the inner cavity of the arc-shaped clamping rod 3, and the installation of the U-shaped frame 4 can be completed.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention.
