[0033] Please refer to Figure 1 、 Figure 2 and Figure 3, the first aspect of the embodiment of the present invention provides a sleeve assembly, comprising: a fixed guide component 11, a movable guide component 12, a spring 13, an extended sleeve 14 and a plurality of guide bolts 15; the fixed guide component 11 is a cylindrical structure, the outer wall of one end of which is provided with a plurality of strip-shaped notches 111 along the axial direction, and the inner wall of the other end is provided with annular grooves 112 and positioning stops 113 in sequence from the inside to the outside along the axial direction; the movable guide component 12 is a cylindrical structure, the side wall of one end of which is provided with screw holes 121 corresponding to the guide bolts 15 along the circumferential direction, and the shape of the end portion of the other end matches the structure of the preset installation position; the spring 13 is arranged in the fixed guide component 11, one end of which is connected to the annular groove 112, and the other end is connected to the movable guide component 12 The movable guide member 12 is connected at one axial end; the guide bolt 15 passes through the strip-shaped notch 111 and is connected to the screw hole 121 of the movable guide member 12; the extended sleeve 14 includes a tool section 141 and an extended section 142. The end of the tool section 141 is provided with a first regular polygonal groove 143 that matches the bolt to be tightened, and the end of the extended section 142 is provided with a second groove 144 that matches the tightening tool. The connection between the extended section 142 and the tool section 141 is provided with a flange 145. The tool section 141 is disposed within the spring 13 and the movable guide member 12. The extended sleeve 14 can reciprocate axially within the movable guide member 12 and the spring 13. The flange 145 is retained by the positioning stop 113 within the fixed guide member 11. By using the extended sleeve 14, the sleeve assembly increases the working distance of the sleeve and improves the convenience of sleeve use. By using a movable guide member that matches the structure of the preset position, the time required for positioning is reduced and the positioning speed is improved.

[0034] The spring 13 pushes the movable guide component 12 to return to its original position after the sleeve assembly completes the bolt installation process.

[0035] Optionally, the tool section 141 and the extension section 142 of the extension sleeve 14 are integrally formed or threadedly connected.

[0036] Optionally, there are four strip-shaped notches 111 , which are evenly distributed along the circumferential direction on the outer wall of the fixed guide component 11 .

[0037] Optionally, the two sides of the strip-shaped notch 111 perpendicular to the fixed guide member 11 are arc-shaped. The two arc-shaped sides of the strip-shaped notch 111 match the shape of the guide bolt 15 that reciprocates therein, which can reduce wear between the strip-shaped notch 111 and the guide bolt 15 and increase service life.

[0038] In one embodiment of the present invention, the width of the strip-shaped notch 111 is smaller than the diameter of the head of the guide bolt 15 and larger than the diameter of the shank of the guide bolt 15. After the guide bolt 15 is connected to the screw hole 121 of the movable guide member 12, the length of the strip-shaped notch 111 is the distance that the guide bolt 15 moves in the axial direction.

[0039] The sleeve assembly further includes a guide tube 16 of an annular structure disposed inside the movable guide component 12 , and the inner wall of the cylindrical hollow structure of the movable guide component 12 is tightly connected to the outer wall of the guide tube 16 .

[0040] Optionally, the guide tube 16 is made of copper. The copper guide tube 16 can reduce the wear of the extension sleeve 14 on the movable guide component 12, while reducing the friction between the extension sleeve 14 and the movable guide component 12, thereby increasing the service life of the movable guide component 12.

[0041] A magnet 146 is provided at the bottom of the first groove 143. The magnet 146 can secure the fixing bolts to be installed, preventing one or more fixing bolts from falling due to shaking or collision during installation, thereby improving the success rate of bolt installation in one go, reducing the probability of repeated installation, and shortening the time required for bolt installation.

[0042] The width of the annular groove 112 matches the wire diameter of the spring 13. The annular groove 112 fixes one side of the spring 13, so that the spring 13 provides a thrust for returning the moving guide member 12 when the moving guide member 12 moves.

[0043] Figure 4 It is a schematic diagram of the three-dimensional structure of the positioning assembly provided by an embodiment of the present invention.

[0044] Please refer to Figure 4 A second aspect of an embodiment of the present invention provides a fastening device comprising a sleeve assembly and a positioning assembly. The positioning assembly comprises: a mounting plate 22 having a plurality of through-holes 21 and a plurality of support columns 23 disposed at the bottom of the mounting plate 22. The through-holes 21 correspond one-to-one to the sleeve assemblies. The support columns 23 are fixedly connected to an external mounting platform. The sleeve assembly is disposed within the through-holes 21 of the mounting plate 22, and the end of the sleeve assembly's fixed guide component 11, which is provided with a positioning stop 113, is connected to the top of the mounting plate 22. This fastening device, through the coordinated use of the sleeve assembly and the positioning assembly, solves the problem of inconvenience in bottom-up installation of shock absorber bolts due to the greater depth inside the vehicle wheel arch, thereby improving installation speed, saving installation time, and increasing vehicle production speed.

[0045] Optionally, the mounting plate 22 is in the shape of a C-shaped plate. The groove in the middle of the C-shaped plate matches the shape of the shock absorber, and the shock absorber is placed in the C-shaped plate groove during installation, which increases the installation speed of the shock absorber.

[0046] The bottom of the support column 23 is fixedly connected to the assembly tooling of the production line chassis. When rising and assembling, the installer holds the support column 23 to adjust the shock-absorbing posture. After adjusting it into place, the extended section 142 of the extended sleeve 14 is rotated upward for pre-tightening. Finally, a tightening tool is used to align the tightening bolts at the bottom of the sleeve to tighten it to complete the installation process.
