Thus, each spring has a pair of clamping hooks 23 and a clamping groove 32 corresponding to the third fastener. Each pair of clamping hooks and clamping grooves are clamped with each other to lock each spring in a compressed state, so that multiple springs are locked in a compressed state in a row by a third fastener 3. When unlocking, pulling the third fastener 3 drives the elastic end of the clamping hook of the spring to move away from the clamping groove, so as to release the clamping and clamping cooperation of the clamping hook and the clamping groove.

The rest is the same as Embodiment 3, which will not be described here.

[0116] Embodiment 5

[0117] Referring to FIG. 33-44, the application further provides a spring module including a plurality of springs, the plurality of springs 1 being mounted to a base 2 at one end along the axial direction, the base 2 coupling the plurality of springs 1 into a spring group arranged in a horizontal and vertical alignment; the top upper cover of the spring 1 being provided with an expansion sleeve 13 for inserting a plug 35, the expansion sleeve 13 having elasticity in the direction of the radial contraction, and the bottom of the spring being provided with a plug cavity;

[0118] The third fastener 3 is arranged at the upper end of the spring group 1 along the axial direction, and is provided with a plug 35 corresponding to the spring group 1. The plug 35 of the third fastener 3 is inserted into the expansion sleeve 13 inside the spring 1 through the insertion hole 15 of the upper cover, and the expansion sleeve 13 and the plug 35 are matched to insert the third fastener 3 on the spring group 1, as shown in FIGS. 38 and 39. The plug 35 of the third fastener or the expansion sleeve 13 of the upper cover is pressed against the plug cavity of the base along the radial outward direction to insert the plug and lock the spring group in the compressed state. The expansion sleeve 13 in the upper cover serves as a receiving member of the third fastener and as a plug of the second fastener, and is inserted into the plug cavity of the base alone or together with the third fastener. In this embodiment, the plug cavity of the base is a plug cavity.

[0119] Specifically, the spring 1 is installed at one end of the base 2 along the axial direction, and a convex cavity 16 is arranged as a plug cavity. The convex cavity 16 is tapered along the height direction.

[0120] Preferably, the plug 35 of the third fastener includes a connecting portion 351 and a plug portion 352. The plug portion 351 is inverted tapered along the direction of insertion into the convex cavity 16, and the upper end of the plug portion 352 is larger in diameter than the connecting portion 351, so that the plug portion 352 is not easily pulled out of the expansion sleeve 13 after passing through the expansion sleeve 13.

[0123] Embodiment 6

[0124] Referring to FIG. 45-FIG. 47, the third fastener 3 in this embodiment is provided with a connecting part between two adjacent springs, which is an elastic expansion belt or a flexible belt 36, and is longer than the distance between the two spring end parts. For a single-layer spring, the third fastener 3 can be one, which is connected to the top or bottom of the spring. In this embodiment, it is a double-layer spring, and the third fastener 3 is two, which are connected to the top and bottom of the spring, respectively.

[0125] The third fastener 3 is provided with a mounting hole corresponding to a row or a column of springs, which is used to insert a plug fastener to connect the third fastener 3 with one end of the spring, or the third fastener is provided with a connecting plug fastener corresponding to the position of the spring on the end surface of the spring. Similarly to the above-mentioned embodiments, the other end of the spring is provided with a plug connector that is buckled with the plug fastener, which will not be repeated here. The difference is that when the two adjacent springs are in the released or compressed state, the connecting part 36 between the two springs is in a relaxed state; when one of the two adjacent springs is in an elastic state and the other is in a compressed state, the connecting elastic expansion belt or flexible belt 36 between the two springs is stretched from a relaxed state to a tensioned state by the elastic tension of one end of the spring. The function of the overlong connecting elastic expansion belt or flexible belt 36 is that when the spring is released from the compressed state to the elastic state, the overlong connecting elastic expansion belt or flexible belt 36 will pull the next group of springs to unlock only after being stretched and tensioned, so that the springs can be unlocked in turn with a certain time difference, that is, the time interval of the release of adjacent springs can be adjusted, or only one spring can be released by pulling the third fastener 3 once, and the release of adjacent springs needs to be operated again.

[0126] The above is only the preferred specific embodiment of the present application, but the design concept of the present application is not limited to this. Any skilled person in the art can make non-essential changes to the present application within the technical scope disclosed by the present application, which is an act of infringing the protection scope of the present application.
