It includes: the support 21 of support 12 bottom of damping spring and the boss 22 being axially moved for limiting damping spring 12 along cylinder body 11,
The shape of support 21 is consistent with the shape of lock ring 132, and boss 22 is fixedly connected on the top of support 21, lower spring mounting seat 2
It is centrally formed with the central through hole 3 through central tube 131, the inner wall of central through hole 3 is equipped with and the spiral shell of 131 outer wall of central tube cooperation
The shape of line, above-mentioned support 21 and lock ring 132 is discoid, if equidistantly offering around the circumferential surface of support 21 and lock ring 132
It is dry to clamp positioning groove 4, it is U-shaped to clamp positioning groove 4.
In the present invention, when being compressed to damping spring 12, central tube 131 is moved up along the axial court of cylinder body 11
It is dynamic, since lower spring mounting seat 2 is fixedly connected with the outer wall thread of central tube 131, and the bottom branch of damping spring 12
On support 21, central tube 131 cooperates lower spring mounting seat 2 to carry out the first second compression, the first second compression to damping spring 12 for support
After finishing, since lower spring mounting seat 2 is cooperatively connected with the outer wall thread of central tube 131, pass through spanner clamping support 21
On clamping positioning groove 4, lower spring mounting seat 2 can be turned upward or downward along central tube 131 is axial, it is right
The reduction length of damping spring 12 under compressive state is finely adjusted, and the length adjustment of damping spring 12 under compression is complete
Bi Yihou rotates lock ring 132 by the clamping positioning groove 4 on spanner clamping lock ring 132, so that lock ring 132 abuts support 21
Bottom, ensure that stability of the lower spring mounting seat 2 on central tube 131；When being extended to damping spring 12, will in
Heart pipe 131 moves downward along the axial direction of cylinder body 11, since lower spring mounting seat 2 is cooperated with the outer wall thread of central tube 131
It is connected and fixed, moreover, the top of one side damping spring 12 is connected in upper spring mounting base, on the other hand, damping spring
12 bottom is supported on the boss 22 that on support 21 and the restricted damping spring 12 of cooperation is axially moved along cylinder body 11, central tube
131 cooperate lower spring mounting seat 2 to carry out first time elongation to damping spring 12, are elongated after finishing for the first time, due to lower spring
Mounting base 2 is cooperatively connected with the outer wall thread of central tube 131, can by the clamping positioning groove 4 on spanner clamping support 21
To turn lower spring mounting seat 2 upward or downward along central tube 131 is axial, to the damping spring under elongated condition
12 elongation length is finely adjusted, and after the length adjustment of the damping spring 12 under elongated condition finishes, passes through spanner clamping
Clamping positioning groove 4 on lock ring 132 rotates lock ring 132, so that lock ring 132 abuts the bottom of support 21, ensure that lower spring
Stability of the mounting base 2 on central tube 131.
Above-mentioned position-limiting unit 14 of stating includes stop collar 141 and circlip 142, and circlip 142 is fastened on the bottom inside stop collar 141
End, the top of stop collar 141 is fixedly connected with the bottom of central tube 131, and cylinder body 11 is distributed with from top to bottom several blocks card
The annular slot 5 of spring 142, stop collar 141 are set in the outside of cylinder body 11 and are located at the lower section of stroke adjustment unit 13, stop collar
141 cooperate 5 stroke-limit of annular slot to adjust unit 13 by circlip 142.
In the present invention, when being moved up or down central tube 131 along 11 axial direction of cylinder body, due to center
The bottom of pipe 131 is fixedly connected with stop collar 141, and position-limiting unit 14 follows central tube 131 to be moved, when by central tube 131

Position fix.
In the use of the present invention, a is greater than the length of damping spring 12 when the buffer of damper stroke length of needs is a,
It needs to elongate damping spring 12 at this time, central tube 131 be moved downward along the axial direction of cylinder body 11, central tube 131 is matched
It closes lower spring mounting seat 2 and first time elongation is carried out to damping spring 12, since the elasticity of damping spring 12 is larger, it is difficult to ensure that subtracting
Shake spring 12 first time elongate it is difficult to ensure that the length of damping spring 12 be accurately be a, for the first time elongate finish after, pass through
Clamping positioning groove 4 on spanner clamping support 21, can by lower spring mounting seat 2 along central tube 131 it is axial upward or
It is turned downward, the elongation length of the damping spring 12 under elongated condition is finely adjusted, so that the elongation of damping spring 12
Length is accurately a, ensure that the precision controlling that damping spring 12 elongates；When the buffer of damper stroke length of needs is b, b
Less than the length of damping spring 12, need to compress damping spring 12 at this time, by central tube 131 along the axial direction of cylinder body 11
It is moved upwardly by, central tube 131 cooperates lower spring mounting seat 2 to carry out the first second compression to damping spring 12, due to damping spring 12
Elasticity it is larger, it is difficult to ensure that the first second compression of damping spring 12 it is difficult to ensure that the length of damping spring 12 be accurately be b, the
After first compression finishes, by the clamping positioning groove 4 on spanner clamping support 21, can by lower spring mounting seat 2 along
Central tube 131 is axial to be turned upward or downward, is finely adjusted to the reduction length of the damping spring 12 under elongated condition,
So that the reduction length of damping spring 12 is accurately b, the precision controlling that damping spring 12 compresses ensure that.
