The number of the upper shock absorption elastic bodies 21 is at least two, and the end part of each upper shock absorption elastic body 21 facing the upper inner surface is fixedly connected with the upper mounting plate 29; for example, the number of the upper shock-absorbing elastic bodies 21 may be four, and the four upper shock-absorbing elastic bodies 21 are connected to four corners of the upper mounting plate 29, so that the acting force of the elastic bodies on the upper side of the main bracket 27 is uniformly distributed, thereby achieving a uniform shock-absorbing effect. Similarly, the number of the lower shock absorbing elastic bodies 22 is at least two, and the end of each lower shock absorbing elastic body 22 facing the lower inner surface 12 is fixedly connected with the lower mounting plate 29A.

Alternatively, the main housing may be in the shape of a cuboid with an upper opening, so that a cover plate may be mounted on the main housing and close the upper opening thereof.

In some embodiments, as shown in fig. 1 to 3 and 5, the mount 30 of the shock absorber 100 is connected to the first connecting portion 28 of the main bracket 27 and is used for direct connection with an electronic device such as a motion camera.
