[0002] The shock absorber as a whole is composed of a spring sleeve arranged on the outside of the shock absorber and fixed by upper and lower covers, so that the spring is compressed and restricted to a fixed position to prevent it from tilting or falling off. When the shock absorber as a whole needs to be repaired and disassembled, the shock absorber and the spring need to be disassembled and separated. However, during the disassembly, the existing device is prone to lose the fixation of the spring when compressing the spring, so that the spring pops out instantly, which can easily cause personal injury and damage to objects. In addition, the springs of the shock absorber have various sizes. When disassembling and assembling, the disassembler needs to be replaced to adapt to the spring size. This makes it very inconvenient to use, time-consuming and labor-intensive, and affects work efficiency.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1

[0026] In order to solve the problem that the spring may pop out when the spring is compressed, this embodiment provides a car shock absorber spring disassembly and assembly tool set, please refer to Figure 1-Figure 7, including two symmetrical hollow grips 1, the upper end of the outer wall of the grip 1 is provided with a clamping assembly 2, the clamping assembly 2 includes a lower clamping seat 20 and an upper clamping seat 21 and a hexagonal long screw 22 rotatably installed in the grip 1, one end of the hexagonal long screw 22 partially extends into the grip 1 and is threadedly connected to the second internal thread 212, and one end of the hexagonal long screw 22 extends out of the bottom of the grip 1, which is convenient for rotating the hexagonal long screw 22. The upper clamping seat 21 is used to drive the spring to contract and move closer to the lower clamping seat 20 that fixes the spring to tighten the spring. Compression, the lower clamping seat 20 includes an upper clamping block 201 sleeved on the upper end of the outer wall of the grip 1, a lower clamping block 203 is provided below the upper clamping block 201 and is threadedly connected to the upper end of the outer wall of the grip 1, and a fixing block 205 is provided above the upper clamping block 201 and is threadedly connected to the upper end of the outer wall of the grip 1. When the spring is compressed, the upper clamping block 201 is rotated to make the upper clamping block 201 close to the lower clamping block 203, and then the fixing block 205 is rotated above the upper clamping block 201 to thereby clamp the upper clamping block 201 and the lower clamping block 203. The block 203 is limited so that the spring is limited. The upper clamping seat 21 includes a slide bar 211 that slides inside the handle 1, and the slide bar 211 is provided with a second internal thread 212 that cooperates with the hexagonal long screw 22. The upper end of the slide bar 211 is provided with a block 213, and one end of the block 213 is provided with a slot 214. The hexagonal long screw 22 is rotated, and the slide bar 211 is driven downward as the hexagonal long screw 22 rotates, thereby moving the block 213 and the slot 214 thereon downward, so that the slot 214 of the block 213 is 14 fits the surface of the spring, and then continues to rotate the long hexagonal screw 22 to make the block 213 drive the spring to follow the slide rod 211 to move closer to the clamping seat 20. A connecting component 3 is provided between the two sets of grip rods 1 to connect the two clamping components 2. The connecting component 3 includes a slide 30, and a slide rail 31 slides inside the slide 30. The positions of the slide 30 and the slide rail 31 are adjusted, and the two clamping components 2 are connected through the connecting component 3 to reduce the range in which the spring will not escape the control of the clamping component 2 during compression and disassembly.

[0027] Considering that the spring needs to be fixed to limit the position when it is compressed, refer to Figure 1-Figure 7 Therefore, an upper clamping groove 202 is provided at one end of the upper clamping block 201, and a lower clamping groove 204 is provided at one end of the lower clamping block 203, and the lower clamping groove 204 is matched with the upper clamping groove 202. By bringing the upper clamping block 201 and the lower clamping block 203 closer together, the upper clamping groove 202 and the lower clamping groove 204 are brought closer together, and the spring is limited by the clamping groove, so that it is not easy to pop out of the control of the lower clamping seat 20 when compressed.

[0028] Considering that the spring force is too large when the spring is compressed, it is easy to cause the clamping seat on one side to lose control of the spring. Figure 1 and Figure 7Therefore, the fixing bolt 32 of the fixed slide rail 31, the slide seat 30 and one end of the slide rail 31 are bolted to the connecting seat 33, and the connecting seat 33 is sleeved on the outer wall of the slide rod 211. Before compressing the spring, the slide rail 31 is pulled out of the slide seat 30 so that the slide rail 31 and one end of the slide seat 30 are bolted to one end of the connecting seat 33 respectively, and the fixing bolt 32 is rotated to prevent the slide rail 31 from sliding. By bolting the slide rail 31 and the slide seat 30 to the connecting seat 33, when the spring is compressed, even if one side loses control of the spring, the spring will not pop out instantly, thereby improving safety in use.

[0029] Considering the different pitches of the springs, see Figure 1-Figure 5 , it is necessary to fit the surface of the spring during disassembly. Therefore, an external thread 10 is provided on the upper end of the outer wall of the grip rod 1, and a first internal thread 206 is provided inside the fixing block 205 and the lower clamping block 203 to match the external thread 10 on the upper end of the grip rod 1. By rotating the fixing block 205 to make it rotate and move vertically at the same time, it drives the upper clamping block 201 to slide on the upper end of the grip rod 1, so as to adjust the distance between the upper clamping block 201 and the lower clamping block 203 so that the spring is located inside the upper clamping groove 202 and the lower clamping groove 204, so that the spring surface can still be fitted even if the pitch of the spring is different.

[0030] Example 2

[0031] On the basis of embodiment 1, considering that the handle 1 needs to be held when the spring is disassembled, and if the surface of the handle 1 is very smooth, it is not easy to hold the handle 1 for operation, refer to Figure 2 Therefore, a grip groove 11 is provided near the lower end of the grip rod 1, and a plurality of protrusions 12 are evenly distributed inside the grip groove 11. The protrusions 12 increase the force-bearing area of ​​the grip rod 1, thereby improving the friction force of the grip rod 1 when gripping.

[0032] Considering that when the hexagonal long screw 22 is rotated, its end will rub against the lower end of the handle 1, which will cause damage over time and reduce the service life. Figure 1-Figure 3 Therefore, a plurality of sliding balls 13 are provided at the lower end of the grip 1 to reduce the friction between the end of the hexagonal long screw 22 and the lower end of the grip 1 and thus improve the service life.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
