[0061] There is a clamping structure between two adjacent connecting rods. The clamping structure includes a first clamping portion 4124 provided at one end of an adjacent connecting rod and a second clamping portion 311 provided at one end of another adjacent connecting rod. The first clamping portion 4124 is clamped to the second clamping portion 311 when the two adjacent connecting rods are screwed into place. The clamping structure plays a feedback role to avoid over-tightening or under-screwing, which helps to ensure the connection stability between the connecting rods.

[0062] The inner tube wall of one end of the connecting rod provided with the plug 41 is provided with an internal thread. The plug 41 also includes a male end cover 412, and the male end cover 412 is provided with a clamping block 4121 located outside the male terminal 411, and the clamping block 4121 is provided with a first clamping portion 4124.

The socket 42 also includes a female end cover 422, and the female end cover 422 is provided with a through hole 4221 connected to the slot 4211. When the internal thread and the external thread are screwed into place, the clamping block 4121 and the female end cover 422 are abutted. When the matching screw is in place, the first clamping portion 4124 is clamped in the second clamping portion 311, thereby improving the connection stability between the connecting columns 31.

[0063] The clamping block 4121 is in an annular structure and surrounds the outer side of the male terminal 411. The clamping block 4121 in an annular structure abuts against the female end cover 422 to further improve the connection stability and avoid shaking.

[0064] The clamping block 4121 is a non-closed annular structure, and includes a first portion 4122 and a second portion 4123. The circumference of the first portion 4122 is smaller than the circumference of the second portion 4123, and the first portion 4122 is provided with a first clamping portion 4124. The first portion 4122 is short in circumference and is easily deformed, so that the first clamping portion 4124 and the second clamping portion 311 are clamped. In this embodiment, the first clamping portion 4124 is a clamping groove, and the second clamping portion 311 is a clamping protrusion.

[0065] A first support ring 312 is also provided on the inner tube wall of one end of the connecting rod provided with the plug 41. The plug 41 also includes a male base 413.
