[0035] For details, please refer to Figure 3-4 , .

[0036] Example 2 Based on Example 1, this example describes the specific structure of the support component 31 in a disc hoisting and protection fixture. Figure 9 As shown, support rods 37 are fixedly connected to the inner walls of both sides of the support base 33, and two symmetrically arranged sliding sleeves 38 are slidably connected to the outer walls of the support rods 37. Support plates 39 are rotatably connected to the outer walls of the two sliding sleeves 38, and one end of the two support plates 39 is rotatably connected to the sliding column 36. Two symmetrically arranged springs 40 are sleeved on the outer walls of the support rods 37. When the sliding frame 25 drives the fixed base 26 to extend, the support rods 37 pull the sliding sleeves 38 to compress the springs 40. When the fixed base 26 is reset, the springs 40 return to their original positions.

[0037] Working principle: In use, first insert the protective sleeve 1 into the disk opening, then rotate the two rotating columns 1-6. When the rotating columns 1-6 rotate, they drive the double-acting screw 29 to rotate. When the double-acting screw 29 rotates, it drives the two trapezoidal blocks 30 to move towards each other. When the two trapezoidal blocks 30 move away from each other, they cooperate with the roller 28 to drive the sliding frame 25 to push the two fixed seats 26 out. When the fixed seats 26 extend, they are pressed against the inner wall of the disk opening by the pressing rubber pad 24, thus facilitating the fixing of the protective sleeve 1 in the disk opening. At the same time, the support rubber pad 8 on the protective sleeve 1 contacts the disk surface, thus preventing damage to the paint on the top of the disk during the installation of the protective sleeve 1. After the protective sleeve 1 is installed, the hoisting rope is passed through the protective sleeve 1 and between the two rollers 12. When the hoisting rope swings, it is supported by the support column 10 and the connecting column 21 to the spring. The roller 12 is compressed to ensure that the suspension rope swings within a certain range. When the position of the roller 12 needs to be adjusted, the rotating column 7 rotates the worm gear 17 to drive the worm wheel 16 to rotate. When the worm wheel 16 rotates, it directly drives the drive disc 15 to rotate. When the drive disc 15 rotates, it pulls the adjusting seat 18 to move through the connecting rod 14. When the adjusting seat 18 slides, it works with the adjusting seat 18 and the support column 10 to adjust the position of the roller 12, thus making it easy to adapt to different specifications of suspension ropes. When the protective sleeve 1 needs to be disassembled, it rotates in the opposite direction, thereby driving the two trapezoidal blocks 30 to move towards each other. At this time, the spring 35 in the support assembly 31 drives the sliding column 36 to return to its original position, thereby pulling the fixed seat 26 to reset. Alternatively, the spring 40 in the support seat 33 drives the two sliding sleeves 38 to move away from each other, thus working with the support plate 39 to pull the sliding column 36 to reset.
