[0001] The utility model relates to the technical field of endocrine body fluid testing, in particular to a variable spring bracket. Background Art

[0002] A spring is a device that can store mechanical energy and has elasticity, usually made of metal. A spring will deform when subjected to force, and will return to its original shape when the external force is reduced or removed. Springs are widely used in various fields, such as mechanical engineering, automotive industry, electronic products, furniture, etc. Common types of springs include compression springs, tension springs, torsion springs, etc. They play the role of support, tension or shock absorption in different scenarios.

[0012] Beneficial effects of the utility model:

[0013] 1. Compared with traditional variable spring brackets, most of them use support blocks to fix the support springs. Most bracket structures are relatively simple, and the initial elasticity of the springs is often fixed, which makes it difficult to meet the use requirements of the springs in different application scenarios, resulting in a relatively single application scenario. By flexibly adjusting the initial elasticity, the initial elasticity of the spring can be flexibly changed according to the actual use requirements of the spring, the flexibility of the bracket can be improved, the application scope of the spring can be effectively expanded, and the practical value of the bracket can be enhanced;

[0014] 2. When adjusting the elastic force of the spring body, the servo motor drives the screw rod to rotate, and the rotating screw rod drives the bottom plate to move up and down, thereby driving the first sliding telescopic rod in the storage groove to synchronously extend and retract. At the same time, the limit ring block is pressed against the top plate, and the moving bottom plate drives the third sliding telescopic rod and the second sliding telescopic rod to synchronously extend and retract, thereby squeezing the spring body to change its initial elasticity, so as to solve the problem that most variable spring brackets have relatively simple bracket structures and the initial elasticity of most springs is often fixed, thereby enhancing the flexibility of bracket use;

[0015] 3. When using the spring body, determine the position of the support rod through the positioning through hole, use the support rod to fix the fixed ring block, use the limit ring block on the fixed ring block to resist the top plate, adjust the initial elastic force of the spring body, use the top plate to withstand the pressure applied to the spring body, transfer the pressure received by the top plate to the spring body, compress the spring body to drive the third sliding telescopic rod to synchronously extend and retract, and perform buffering and shock reduction operations.
