Embodiment Construction
[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] see figure 1 with figure 2 , figure 1 It is an exploded view of a graded spring device provided by the present invention. This embodiment provides a graded spring device 100, which includes a sliding rod 1, a graded spring pressing component 2, a shifting component 3, a limit tube 4, and a third spring 5. The slide rod 1 is used to output elastic force, and the graded spring pressing component 2 is The slide bar 1 provides elastic force, the shifting assembly 3 rotates the graded elastic pressing assembly 2, the limit tube 4 restricts the rotation of the sliding rod 1 and accommodates th...

Description
technical field [0001] The invention relates to the field of spring devices, in particular to a stepped spring device. Background technique [0002] In the field of optical fiber manufacturing, some spring clamps with simple structure are commonly used to clamp multiple parallel products. In the case of clamping many products, due to the large deformation of the spring, the clamping force changes completely linearly with the deformation. , so the clamping force also increases accordingly, and products with smaller thickness cannot be clamped stably, and the product will be deformed by force. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a stepped spring device for solving the problem in the prior art that the clamping force of a spring-type clamp changes completely linearly with the spring deformation. [0004] In order to achieve the above-mentioned technical purpose, the tec...
