[0020] In order to make the purpose, technical scheme and advantage of the utility model embodiment more clearly, the following will be to the technical scheme in the utility model embodiment of the utility model embodiment, clear, complete description, obviously, the described embodiment is the part of the embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making the creative labor are within the scope of the utility model protection.

[0021] The following detailed description of the embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the application claimed, but merely represents the preferred embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the application.

[0022] Referring to Figures 1-5 The elastic spacer ring with shock absorption and buffering effect comprises a spacer ring body 1, two groups of contact rings 2 arranged on the front and back sides of the spacer ring body 1 and coinciding with the center of the spacer ring body 1, a plurality of groups of through holes 3 arranged on the spacer ring body 1 and penetrating through the front and back sides of the spacer ring body 1, a plurality of groups of damping rods 4 connected to one side of the contact ring 2 close to the spacer ring body 1, and the ends of the damping rods 4 respectively extend into the through holes 3, and the damping rods 4 can slide along the inside of the through holes 3. Therefore, when the contact ring 2 is forced to move, it will always coincide with the center of the spacer ring body 1 under the limiting action of the damping rod 4 and will not deviate, thereby ensuring that the contact rings 2 on both sides of the spacer ring body 1 will not be blocked from the lens due to deviation. A plurality of groups of springs 5 are arranged between the two groups of contact rings 2 and the spacer ring body 1, the springs 5 are sleeved on the surface of the damping rod 4, and the springs 5 provide elastic support to the contact rings 2 on the front and back sides of the spacer ring body 1. When the two groups of contact rings 2 are subjected to external impact, the springs 5 will be compressed and deform and convert the impact into elastic potential energy, thereby playing a role in shock absorption and buffering.
