[0030] The working principle of this utility model is as follows:

[0031] During use, the inner tube of the suspension fork can be placed between the three fastening strips 75. At this time, the three fastening strips 75 will only contact the outer wall of the inner tube under the action of the three springs 74. After contact, the inner tube can be fixed. After fixation, the oil pump 91 is started to inject the oil inside the storage barrel 4 into the inside of the connecting hose 92.

The rotation of the threaded rod 64 drives the moving bar 63 to move. The movement of the moving bar 63 causes the L-shaped tube 52 to move upward. The upward movement of the L-shaped tube 52 drives all the atomizing nozzles 55 to move upward. During its upward movement, the infrared rangefinder 51 continuously detects the moving height of the L-shaped tube 52. When it reaches the appropriate height, the oil spraying can be stopped. In this case, the height of the oil spraying can be effectively controlled according to demand.
