Example two

On the basis of the spring support device shown in fig. 1, fig. 2 provides a schematic view of a spring clamping mechanism 1, and as shown in fig. 2, the spring clamping mechanism 1 comprises: the clamping device comprises a clamping connecting piece 101, a first clamping piece 102, a second clamping piece 103, a spring 104, a first pin 105 and a second pin 106;

the clamping connecting piece 101 is connected with the first end of the lifting mechanism 2;

the first clamping piece 102 is connected with the clamping connecting piece 101 through a first pin 105, and the second clamping piece 103 is connected with the clamping connecting piece 101 through a second pin 106;

two ends of the spring 104 are respectively connected with the clamping connecting piece 101 and the second clamping piece 103;

when the second clamping member 103 rotates around the second pin 106 in a direction away from the first clamping member 102 under the action of an external force, so that the diameters of inscribed circles of the first clamping member 102 and the second clamping member 103 are increased, the spring 104 is stretched;

when the external force driving the second clamping member 103 to rotate around the second pin 106 disappears, the spring 104 shortens under the action of its own elastic force, and the second clamping member 103 rotates around the second pin 106 to the direction close to the first clamping member 102 under the driving of the spring 104, so that the damping spring is clamped between the first clamping member 102 and the second clamping member 103.

In the embodiment of the present application, after the spring clamping mechanism 1 moves to the position where the damping spring is located, the second clamping member 103 is driven to move around the second pin 106 in the direction away from the first clamping member 102, so that the diameters of the inscribed circles of the first clamping member 102 and the second clamping member 103 are increased, that is, the openings of the first clamping member 102 and the second clamping member 103 are increased, so that the top of the damping spring can enter between the first clamping member 102 and the second clamping member 103. At which time the spring 104 is stretched. After the top of the damping spring enters between the first clamping piece 102 and the second clamping piece 103, the driving force for driving the second clamping piece 103 to rotate around the second pin 106 is removed, the second clamping piece 103 moves around the second pin 106 to the direction close to the first clamping piece 102 under the action of the spring 104, so that the diameters of inscribed circles of the first clamping piece 102 and the second clamping piece 103 are reduced, namely the openings of the first clamping piece 102 and the second clamping piece 103 are reduced, and the first clamping piece 102 and the second clamping piece 103 clamp the top of the damping spring.
