Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-3, the utility model relates to an elastic member for a spherical pin, which comprises an elastic member main body, wherein the elastic member main body is integrally formed, has a large middle part and small ends, and is provided with a hollow structure to form a cavity 4; at least one boss 8 is arranged outside the middle of the elastic part main body, and the outer diameter of the boss is larger than that of the main body.

As a technical improvement, the elastic part main body comprises a main body part 2 and reducing end heads 1 arranged at two sides of the main body part.

As a technical improvement, a reducing section 61 and a connecting section 6 are arranged between the main body part 2 and the reducing end head 1, the reducing section is in a hollow conical shape, the connecting section is in a hollow column shape, the connecting section is adjacent to the reducing end head 1, and the reducing section is adjacent to the main body part 2.

As a technical improvement, the outer diameter of the connecting section is larger than the maximum outer diameter of the reducing end 1.
