[0002] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0003] For newly developed motorcycles, after the motorcycle is assembled, a series of tests need to be carried out to ensure the rationality of the later motorcycle design and to ensure safety, stability and durability during use. Among them, the handlebar fatigue strength and durability test is an important test item. The purpose of this project is to test the strength of the motorcycle handlebars, find out the deficiencies and make corrections, so as to save the product launch cycle and improve the quality of the product launch. At present, the fatigue strength and durability test of motorcycle handlebars is carried out manually, which requires manual labor to lift the handlebars of the whole vehicle with tools, and then put them down, and repeat this action continuously. Since the weight of the whole vehicle is very heavy, it is time-consuming and labor-intensive to lift the handlebars, which increases the labor cost. Utility Model Content

By arranging an air pressure pump and a balance strap, when the air pressure pump moves upward, the handlebar is pulled by the balance strap to lift the vehicle until the front wheel is suspended in the air. When the air pressure pump moves downward, the whole vehicle is lowered. The operation is simple. The worker only needs to tie the motorcycle handlebar with the balance strap, and then the equipment can automatically perform a light handlebar fatigue test. It can be completed without human intervention, thereby greatly saving labor costs and reducing the labor intensity of workers.
