Preferably, the heightening block 7 may be formed into a semicircular ring. The heightening block 7 is sized to be placed in the sleeve 53. The heightening block 7 is used to be cushioned at the bottom of the outer cylinder 91 of the shock absorber 9. When the coil spring 92 is skewed during the compression process, the operator may cushion the heightening block 7 at one side of the bottom of the shock absorber 9 to adjust the deflection of the shock absorber 9 so that the coil spring 92 is more evenly stressed during the compression process to avoid skew again.

[0044] Preferably, Figure 1 As shown, in the embodiment, the driving unit 2 may include a motor 21, a worm wheel 22 and a worm 23.

During use, the motor 21 can drive the worm wheel 22 to rotate, and the worm wheel 22 drives the worm 23 to rotate. The lower end of the worm 23 is threadedly connected to the guide plate 3 to form a screw transmission structure, thereby driving the guide plate 3 to move in the vertical direction to compress the coil spring 92. In addition, preferably, the compression coil spring device for the shock absorber may also include an electric control button 8. The electric control button 8 may be arranged on the outside of the housing 1 and connected to the motor 21 by wires. The electric control button 8 is used to control the steering of the motor 21 to control the lifting and lowering of the guide plate 3.

[0045] Preferably, Figures 1 to 5As shown, in an embodiment, the pressure column 4 may include a support rod 41, a cushion block 42 and a pressure claw 43. Among them, the top end of the support rod 41 may be fixedly connected to the guide plate 3, so that the support rod 41 can move in the vertical direction following the guide plate 3. The bottom end of the support rod 41 may be provided with a mounting block 44, and the mounting block 44 and the bottom end of the support rod 41 may be connected by a retractable cylindrical rod, and a mounting hole may be provided on the mounting block 44. The cushion block 42 may be formed as a circular plate with an arc opening. The cushion block 42 is used to be cushioned between the mounting block 44 and the bottom end of the support rod 41 (i.e., clamped on the cylindrical rod) to adjust the height of the mounting block 44. The thickness of the cushion block 42 may be various, so that the operator can make a choice according to actual needs. By installing cushion blocks 42 of different thicknesses on the two pressure columns 4, the pressure of the two pressure columns 4 on the top end of the coil spring 92 can be adjusted to avoid the coil spring 92 from tilting to one side during the compression process.

[0046] Preferably, Figures 1 to 5 As shown, in an embodiment, the pressing claw 43 can be installed on the mounting block 44. Specifically, the pressing claw 43 can include a pressing plate portion 431 and a mounting rod 432. The pressing plate portion 431 can be formed as an arc-shaped plate member with a straight side, and a convex edge extending perpendicular to the plate surface can also be formed on the arc side of the pressing plate portion 431, so that an arc groove 4310 is formed around the lower side of the pressing plate portion 431. The pressing plate portion 431 is used to press the top end of the coil spring 92, and the top end of the coil spring 92 can be clamped in the arc groove 4310. Preferably, an anti-slip convex point 433 can also be provided on the lower side of the pressing plate portion 431, and the anti-slip convex point 433 can be a rod member extending perpendicular to the plate surface of the pressing plate portion 431. When the pressing plate portion 431 is in contact with the coil spring 92, the anti-slip convex point 433 can be clamped on the inner side of the coil spring 92 to prevent the coil spring 92 from slipping out during the pressing process. One end of the mounting rod 432 can be integrally formed with the pressure plate portion 431 , and the other end of the mounting rod 432 can be inserted into the mounting hole of the mounting block 44 .

[0047] Preferably, Figure 1As shown, in the embodiment, the compression coil spring device for the shock absorber may further include a hanging weight 32. The hanging weight 32 may be connected to the middle of the guide plate 3 through a hanging wire 31. The hanging wire 31 of the hanging weight 32 extends in the vertical direction. When the shock absorber 9 is fixed to the base 5, the hanging wire 31 can be aligned with a positioning point (not shown) on the outer cylinder 91 of the shock absorber 9. Since a screw rod 93 for connecting with the vehicle body is provided on the upper cover of the shock absorber 9, the upper cover of the shock absorber 9 needs to reposition the relative position of the screw rod 93 and the positioning point after twisting, so as to ensure that when the upper end of the shock absorber 9 is connected with the vehicle body, the outer cylinder 91 of the shock absorber 9 can be connected with the U-shaped fork of the vehicle. After the hanging weight 32 is provided, the operator can judge the relative position of the positioning point and the screw rod 93 through the hanging wire 31, so as to easily screw the upper cover of the shock absorber 9 to a suitable position.

[0048] During use, the operator can first install the outer cylinder 91 of the shock absorber 9 on the base 5, and further fix it by clamping the locking part 6. Then observe the rotation direction of the coil spring 92, and install the cushion blocks 42 of different thicknesses on the two pressure columns 4 according to the top heights of the two sides of the coil spring 92. If the coil spring 92 is still skewed during the compression process, a heightening block 7 can be padded in the sleeve 53 of the base 5. After the adjustment is completed, the pressure claw 43 is clamped on the top of the coil spring 92, and the safety door 11 is closed. Thereafter, the electric control button 8 is pressed to start compressing the coil spring 92. During the compression process, the compression degree can be observed through the scale line 12, and whether there is relative movement between the upper cover of the shock absorber 9 and the positioning point on the outer cylinder 91 can be observed through the hanging hammer 32. Finally, the operator can control the motor 21 to rotate in the opposite direction through the electric control button 8, so that the pressure claw 43 is separated from the coil spring 92 to complete the compression.
