[0002] Adjustable supports are commonly used auxiliary parts in various equipment and mechanisms in production and life. They can achieve support at different heights and angles, especially between two working surfaces in a V-shaped groove or other arbitrary angles. They can also be used for connection support of opening and closing mechanisms. Adjustable supports are widely used due to their simplicity and practicality.

[0003] The adjustable support includes a leg and a support connected by a pin. The assembly quality of the leg, support and pin will directly affect the working performance of the adjustable support. At the same time, the pin is the part with the most serious wear and tear during the operation of the adjustable support and requires high-frequency replacement and maintenance. Therefore, the assembly of the pin is a key step in the production of the adjustable support. In order to ensure the flexible adjustment of the adjustable support, a large matching clearance is reserved between the pin and the leg hole and the support groove. The support, leg and pin are all symmetrical structures with high interchangeability, which makes it difficult to position the pin, leg and support during assembly.
