Two fixed rings 14 are in contact with the connecting plate 12, two clamp blocks 15 are in contact with the connecting block 13, and then the clamp block 15 and the connecting block 13 are connected together through the fixed bolt 16, at this time, the two clamp blocks 15 are fixed on the side of the connecting block 13, and then the fixed bolt 16 is fixed, the threaded column 17 is screwed into the inside of the fixed ring 14, the position of the connecting buckle 18 is changed by rotating the threaded column 17, the threaded column 17 is rotated until the appropriate position, and then the connecting buckle 18 and the spring 1 are bolted on the appropriate position of the bicycle, the length of the whole device is changed by the threaded column 17 and the fixed ring 14, and the device length can be switched between long and short according to the actual situation.

[0027] Further, as Figure 1 , Figure 2 and Figure 3As shown, the side wall of the fixed ring 14 is provided with a plurality of holes for the auxiliary bolts 21 to pass through; the side wall of the fixed ring 14 is fixedly connected with a plurality of nuts 2; the inner side wall of the fixed ring 14 is fixedly connected with a limiting plate 22; the limiting plate 22 is in contact with the connecting plate 12. During the operation of the equipment, the auxiliary bolts 21 are also tightened, so that the auxiliary bolts 21 are connected together with the nuts 2, at this time, the limiting plate 22 is above the connecting plate 12, the connecting plate 12 is between the clamping block 15 and the limiting plate 22, and is limited by the limiting plate 22 and the clamping block 15. By arranging the limiting plate 22 and the auxiliary bolts 21, the stability of the connection between the two fixed rings 14 can be increased, and the probability of the fixed ring 14 shaking during the operation of the equipment can be reduced.

[0028] Further, as shown in Figure 1 , Figure 2 and Figure 3 , the outer side wall of the threaded column 17 is rotatably connected with a connecting ring 3; the outer side wall of the connecting ring 3 is fixedly connected with a plurality of connecting rods 31; the outer side wall of the fixed ring 14 is fixedly connected with a plurality of limiting blocks 32; the connecting rod 31 is in sliding contact with the limiting block 32. When installing the equipment, first align the connecting rod 31 with the hole in the middle of the limiting block 32, then rotate the threaded column 17 to the inside of the fixed ring 14, and when the threaded column 17 is rotating, the connecting rod 31 will slide inside the limiting block 32, and the limiting block 32 will limit the direction of the connecting rod 31. By arranging the limiting block 32 and the connecting rod 31, the probability of the threaded column 17 bending during operation can be reduced, and the stability of the equipment during operation can be further increased.

[0029] Further, as shown in Figure 2 and Figure 4 , the side wall of the threaded column 17 is fixedly connected with a limiting ring 4; the limiting ring 4 is in contact with the connecting ring 3. During the operation of the equipment, the connecting ring 3 plays a role in limiting the direction of the threaded column 17, and the limiting ring 4 and the threaded column 17 form a certain limitation on the connecting ring 3. By arranging the limiting ring 4, the stability of the connection between the connecting ring 3 and the threaded column 17 is increased, the situation that the connecting ring 3 is separated from the threaded column 17 during the operation of the equipment is reduced, and the failure rate of the equipment is reduced.

[0030] Further, as shown in Figure 4 , the side wall of the connecting rod 31 is provided with a scale groove 5. During the operation of the equipment, the connecting rod 31 will slide when the threaded column 17 is rotated, at this time, the position of the connecting rod 31 will change, and the workers can quickly understand the overall adjustment of the threaded column 17 through the scale groove 5. By arranging the scale groove 5, the workers can quickly adjust the equipment.

[0031] Further, as shown in Figure 2As shown, a pair of gaskets 6 are fixed to the side walls of the connecting buckle 18. When the equipment is in operation, the staff will use bolts to connect the connecting buckle 18 to the appropriate position of the bicycle. The gaskets 6 can provide a certain cushioning effect on the contact surface. The provision of gaskets 6 can play a role in protecting the surface of the connecting parts and reducing the risk of wear and scratches.

[0032] Further, such as Figure 1 and Figure 2 As shown, the connecting rod 31 is made of a rigid material. When the device is working, the connecting rod 31 will have a certain limiting effect on the connecting ring 3. By setting the connecting rod 31 to be a rigid material, the bending and breaking of the connecting rod 31 during long-term work is reduced.

[0033] Working principle: make the two fixing rings 14 contact with the connecting plate 12, the two clamping blocks 15 contact with the connecting block 13, and then connect the clamping blocks 15 and the connecting block 13 together through the fixing bolts 16. At this time, the two clamping blocks 15 are fixed to the side of the connecting block 13, and then the fixing bolts 16 are fixed. Screw the threaded column 17 into the fixing ring 14, and change the position of the connecting buckle 18 by rotating the threaded column 17. Rotate the threaded column 17 until it is in the appropriate position, and then install the connecting buckle 18 and the spring 1 in the appropriate position on the bicycle through the bolts. By setting the threaded column 17 and the fixing ring 14, the overall length of the equipment can be changed, which is convenient for the staff to adjust the equipment according to the actual situation. The degree can be switched between long and short. When the equipment is working, the auxiliary bolt 21 is also tightened to connect the auxiliary bolt 21 and the nut 2 together. At this time, the limit plate 22 will be above the connecting plate 12, and the connecting plate 12 will be between the clamping block 15 and the limit plate 22. It will be restricted by the limit plate 22 and the clamping block 15. By setting the limit plate 22 and the auxiliary bolt 21, the stability of the connection between the two fixing rings 14 can be increased, and the probability of the fixing ring 14 shaking when the equipment is working can be reduced. When installing the equipment, first align the connecting rod 31 with the hole in the middle of the limit block 32, and then rotate the threaded column 17 to the inside of the fixing ring 14. When the threaded column 17 rotates, due to the gap between the connecting ring 3 and the threaded column 17, the connection between the fixing ring 14 and the threaded column 17 is tightened. The rotation connection, at this time the connecting rod 31 will slide inside the limit block 32, the limit block 32 will limit the direction of the connecting rod 31, by setting the limit block 32 and the connecting rod 31, the probability of the threaded column 17 bending during operation is reduced, and the stability of the equipment during operation is further increased. When the equipment is working, the connecting ring 3 plays a role in limiting the direction of the threaded column 17, and the limit ring 4 and the threaded column 17 form a certain restriction on the connecting ring 3. The limit ring 4 is set to increase the stability of the connection between the connecting ring 3 and the threaded column 17, and reduce the situation where the connecting ring 3 is separated from the threaded column 17 when the equipment is working, thereby reducing the failure rate of the equipment. When the equipment is working, the staff will rotate the threaded column 17, and the connecting rod 31 It will slide along, and the position of the connecting rod 31 will change at this time. The staff can quickly understand the overall adjustment of the threaded column 17 through the scale groove 5. The set scale groove 5 is convenient for the staff to quickly adjust the equipment. When the equipment is working, the staff will connect the connecting buckle 18 to the appropriate position of the bicycle through bolts. The gasket 6 can provide a certain buffer for the contact surface. The set gasket 6 can protect the surface of the connecting component and reduce the risk of wear and scratches. When the equipment is working, the connecting rod 31 will have a certain restrictive effect on the connecting ring 3. The material of the connecting rod 31 is a rigid material, which reduces the risk of bending and breaking of the connecting rod 31 during long-term work.
