Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples:

referring to fig. 1-2, the utility model provides a tricycle damper, which comprises a cavity tube 1, wherein an inner tube 2 is installed in the cavity tube 1, a first clamping ring 3 is integrally arranged on the inner side surface of the cavity tube 1, a first inner threaded tube 4 is communicated with the bottom of the cavity tube 1, a second clamping ring 5 is integrally arranged on the outer side surface of a body of the inner tube 2 positioned in the cavity tube 1, a second inner threaded tube 6 is communicated with the top of the inner tube 2, the second clamping ring 5 is positioned below the first clamping ring 3, a spring 7 is installed in a connecting body inner cavity of the cavity tube 1 and the inner tube 2, two ends of the spring 7 are sleeved on the first inner threaded tube 4 and the second inner threaded tube 6, and a connector 8 is installed at the positions of the first inner threaded tube 4 and the second inner threaded tube 6 in a threaded manner.
