[0017] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of the present utility model, and does not strictly limit the specific protection scope claimed by the present utility model.

[0018] As Figures 1-3As shown in the figure, an automated precision metal fitting includes a fixed tube 1. A plug-in tube 2 is inserted into the top of the fixed tube 1. A lead screw 3 is rotatably installed through the bottom of the fixed tube 1. A moving block 4 is screwed onto the outer wall of the lead screw 3 and is located inside the plug-in tube 2. The outer wall of the moving block 4 is fixed to the inner wall of the plug-in tube 2. A piston rod 7 is inserted into the top of the plug-in tube 2. A piston 8 that is damping-slid with the plug-in tube 2 is fixed to the bottom end of the piston rod 7. A partition 6 is arranged inside the plug-in tube 2 and is located below the piston 8. An adjusting assembly is arranged above the plug-in tube 2 on the outer wall of the piston rod 7. The structure is simple and the operation is convenient. By rotating the lead screw 3, the lead screw 3 drives the moving block 4 to move, and the moving block 4 drives the plug-in tube 2 to move, so that the overall length of the device can be adjusted, which is convenient for the installation of bicycles of different sizes and improves the flexibility of device installation. The adjusting assembly includes an external thread 11 arranged on the outer wall of the piston rod 7. An adjusting disk 10 is screwed onto the outer wall of the piston rod 7 corresponding to the external thread 11. A spring 12 is arranged below the adjusting disk 10 on the outer wall of the piston rod 7. A fixed disk 13 that limits the spring 12 is arranged at the top of the plug-in tube 2. The structure is simple. By the cooperation of the adjusting disk 10 and the external thread 11, the adjusting disk 10 can be rotated to adjust the pitch of the spring 12, which improves the flexibility of device use. A chute is opened inside the fixed tube 1. A slider 15 that is slidably connected with the chute is fixed to the outer wall of the plug-in tube 2, which enables the stable up and down movement of the plug-in tube 2. It is relatively perfect and can also limit the movement of the plug-in tube 2, which improves the stability of device use.

[0019] As Figure 1 and 3 shown in the figure, an annular groove is opened at the bottom of the fixed tube 1. A slip ring 14 is rotatably installed inside the annular groove. Two reinforcing rods that are fixed to the first connecting ear 5 are fixed to the bottom of the slip ring 14, which increases the connection strength of the first connecting ear 5.

[0020] As Figures 1-3 shown in the figure, a second connecting ear 9 is rotatably installed at the top of the piston rod 7, which improves the overall integrity and is convenient for the installation of the device.

[0021] As Figure 3 shown in the figure, a limit block is arranged at the top of the lead screw 3, which is convenient for limiting the movement of the moving block 4 and is relatively practical.

[0022] The working principle of the present utility model is as follows: When in use, rotate the first connecting ear 5. The first connecting ear 5 drives the lead screw 3 to rotate. The lead screw 3 drives the plug-in tube 2 on the moving block 4 to move. The plug-in tube 2 drives the second connecting ear 9 at the top of the piston rod 7 to move, and the distance between the first connecting ear 5 and the second connecting ear 9 can be adjusted to adapt to the installation of bicycle shock absorbers of different sizes. By rotating the adjusting disk 10, the adjusting disk 10 cooperates with the external thread 11 and the adjusting disk 10 moves. The adjusting disk 10 squeezes the spring 12, and the pitch of the spring 12 can be adjusted, thereby improving the flexibility of device use.

[0023] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
