The left clamping block 211 and the right clamping block 212 are spaced at the first end 214 of the clamp 210, the clamp 210 further comprises a pin shaft 215 and an elastic piece 216, the pin shaft 215 is rotatably connected with the spanner 220 after the first end 214 of the clamp 210 penetrates through the left clamping block 211 and the right clamping block 212, and the elastic piece 216 is connected with the left clamping block 211 and the right clamping block 212 at the first end 214 of the clamp 210 and accumulates elastic force; referring to fig. 2 and 3, the trigger 220 has an operation end 221 and a driving end 222, the driving end 222 is provided with a cam 223, the driving end 222 can be controlled to drive the cam 223 to rotate relative to the right clamping block 212, when the radially reduced area of the cam 223 rotates to be opposite to the right clamping block 212, the elastic member 216 releases the elastic force to separate the left clamping block 211 and the right clamping block 212 from each other at the first end 214 of the clamp 210, so as to release the limitation of the expanding of the clamping space 213; referring to fig. 2 and 4, the knob 230 has a limiting end 231 and a rotating end 232, the limiting end 231 is abutted to the left clamping block 211 or the right clamping block 212, for example, fig. 2 illustrates that the limiting end 231 is abutted to the left clamping block 211, the rotating end 232 can be rotated to drive the limiting end 231 to move away from the clamping band 210, when the limiting end 231 moves away from the clamping band 210, the elastic member 216 releases elastic force to separate the left clamping block 211 and the right clamping block 212 from each other at the first end 214 of the clamping band 210, and further the limitation of the expanding of the clamping space 213 can be further released.
