[0031] A coupling 11 is mounted on the stabilizing seat 7 .
[0032] One end of the coupling 11 is connected to a rotating shaft 12 .
[0033] Connecting blocks 13 are connected to both ends of the connecting rod 10 , and a rotating ring 14 is rotatably connected to the fixing sleeve 8 .
[0034] A rotating groove 15 is formed on the rotating ring 14 , and the rotating groove 15 is adapted to the connecting rod 10 . A passing groove 16 is formed on the rotating groove 15 , and the passing groove 16 is adapted to the connecting block 13 .
[0035] In this embodiment, during use, the coupling 11 is fixed to one end of the mounting base 1 by manually using the stabilizing seat 7, and the fixing base 3 is slid along the sliding plate 2 on the mounting base 1, and the sliding process is stopped after it slides to a suitable position, and the connecting bolt 5 is used to complete the fixing process between the fixing base 3 and the mounting base 1, so that during the driving process of the motor 4, the coupling 11 is used to drive the rotating shaft 12 to rotate. During use, when the position of the moving block 24 needs to be adjusted, the rotating ring 14 is manually rotated, and the rotation is stopped after the through groove 16 on the rotating ring 14 is rotated to a position that coincides with the connecting block 13. The sliding block 9 is slid along the outside of the fixed sleeve 8. During the sliding process, the connecting block 13 at one end of the connecting rod 10 abuts against the slidingly connected moving block 24 on the fixed sleeve 8, thereby compressing the tension spring 23 between the fixed sleeve 8 and the moving block 24. As the sliding block 9 continues to move, the connecting block 13 at the other end of the connecting rod 10 moves to a suitable position, and then the connecting block 13 abuts against one end of the rotating ring 14. At this time, the rotating ring 14 is rotated so that the through groove 16 on the rotating ring 14 is away from the connecting block 13, and the sliding block 9 is released so that the connecting block 13 and the rotating ring 14 complete the abutment process, thereby fixing them.
[0036] See also Figure 2-4 , as an implementation method of a torque protection device for the protection component: the protection component includes a rotating rod 17, a fixed groove 18 and a rolling groove 19, the rotating rod 17 is slidably connected to the inner side of the fixed sleeve 8, the fixed groove 18 is opened on the rotating rod 17, and the rolling groove 19 is opened on the fixed sleeve 8.
[0037] A rolling ball 20 is provided on the rolling groove 19 in a sliding and rolling connection, and a sliding rod 21 is provided on the fixed sleeve 8 in a sliding connection. There are multiple sliding rods 21, and two sliding rods 21 form a group. Each group of sliding rods 21 is connected with a protruding block 22, which abuts against the rolling ball 20.
[0038] The fixed sleeve 8 is connected with a tension spring 23 , and the tension spring 23 is connected with a moving block 24 . The moving block 24 is slidably connected to the fixed sleeve 8 , and one end of the moving block 24 abuts against one of the connecting blocks 13 and the rolling ball 20 .
[0039] More specifically, the driving end of the motor 4 drives the fixed sleeve 8 to rotate. During the rotation process, when the rotating rod 17 connected to the coupling 11 rotates, and if it gets stuck during the rotation, the sliding rod 21 slidably connected to the fixed sleeve 8 will slide out of the fixed sleeve 8, and drive the protruding block 22 on the sliding rod 21 to move, so that the ball 20 connected to the rolling groove 19 on the fixed sleeve 8 moves, thereby making the sliding rod 21 move away from the fixed groove 18 on the rotating rod 17, so that the rotation process of the rotating rod 17 is released and it is caused to idle.
[0040] In summary, when the overall device is in use or running: during use, the coupling 11 is fixed to one end of the mounting base 1 by manually using the stabilizing seat 7, and the fixing base 3 is slid along the sliding plate 2 on the mounting base 1, and the sliding process is stopped after it slides to the appropriate position, and the connecting bolt 5 is used to complete the fixing process between the fixing base 3 and the mounting base 1, so that during the driving process of the motor 4, the coupling 11 is used to drive the rotating shaft 12 to rotate. During use, when the position of the moving block 24 needs to be adjusted, the rotating ring 14 is rotated manually, and the through groove 16 on the rotating ring 14 is rotated to a position that coincides with the connecting block 13 and stops. Stop rotation, and slide the sliding block 9 along the outside of the fixed sleeve 8. During the sliding process, the connecting block 13 at one end of the connecting rod 10 abuts against the slidingly connected moving block 24 on the fixed sleeve 8, thereby compressing the tension spring 23 between the fixed sleeve 8 and the moving block 24. As the sliding block 9 continues to move, the connecting block 13 at the other end of the connecting rod 10 moves to a suitable position, so that the connecting block 13 abuts against one end of the rotating ring 14. At this time, the rotating ring 14 is rotated so that the through groove 16 on the rotating ring 14 is away from the connecting block 13, and the sliding block 9 is released so that the connecting block 13 and the rotating ring 14 complete the abutment process, thereby fixing it.
[0041] The driving end of the motor 4 drives the fixed sleeve 8 to rotate. During the rotation process, when the rotating rod 17 connected to the coupling 11 rotates, and if it gets stuck during the rotation, the sliding rod 21 slidably connected to the fixed sleeve 8 will slide out of the fixed sleeve 8, and drive the protruding block 22 on the sliding rod 21 to move, so that the ball 20 rollingly connected to the rolling groove 19 on the fixed sleeve 8 moves, thereby making the sliding rod 21 move away from the fixed groove 18 on the rotating rod 17, so that the rotation process of the rotating rod 17 is released and it is caused to idle.
