[0032] The following is an implementation of a linkage mechanism:

[0033] Such as Figure 4-6 As shown: the lower end of the lower push rod assembly 10 is connected with a push rod rotating part 100, the upper end of the front support rod assembly 2 is connected with a front support rod rotating part 20, and the upper end of the rear support rod assembly 3 is connected with a rear support rod rotating part 30, The push rod rotation member 100, the front support rod rotation member 20 and the rear support rod rotation member 30 are rotatably connected by a first shaft 64.

[0034] The linkage mechanism includes a first arc groove 60 opened on the push rod rotating part 100, a second arc groove 61 opened on the front support rod rotating part 20, a linear groove 62 opened on the rear support rod rotating part 30, and a sliding At block 63, the distance between the first arc-shaped groove 60 and the first shaft 64 gradually increases from top to bottom, and the distance between the second arc-shaped groove 61 and the first shaft 64 gradually decreases from top to bottom. The distance between the groove 62 and the first shaft 64 gradually decreases from top to bottom, and the sliding block 63 is provided with a shaft hole 630 and a sliding groove 631 extending along its length. The first shaft 64 passes through the sliding groove 631 of the sliding block 63; a second shaft 65 passes through the first arc-shaped groove 60, the second arc-shaped groove 61, the linear groove 62 and the shaft hole 630 of the sliding block 63 at the same time. The shaft 65 can slide in the first arc groove 60, the second arc groove 61, and the linear groove 62. When the push rod assembly 1 is pushed, the push rod rotating part 100 rotates, and the second shaft 64 in the first arc-shaped groove 60 slides. Driven by the sliding block 63, the second shaft 64 is in the linear groove of the rear support rod rotating part 30. 62. Synchronous sliding in the second arc-shaped groove 61 of the front support rod rotating member 20, thereby driving the front support rod assembly 2 and the rear support rod assembly 3 to rotate synchronously, realizing the linkage of rotation. The structure of the linkage mechanism is not limited to this, and any structure capable of realizing the linkage function can be used, which will not be repeated here.

[0035] In addition, the lower end of the push rod assembly 1, the upper end of the front strut assembly 2 and the upper end of the rear strut assembly 3 are provided with a rotating housing 7, and the linkage mechanism is arranged in the rotating housing 7.
