A springback device is arranged between the clamping piece 3 and the first connecting piece 1. The external diameter size of joint spare 3 is less than the internal diameter size of joint chamber 10 to joint spare 3 can remove and the moving direction perpendicular to in joint chamber 10 the axial of joint post 21. The clamping member 3 is configured to at least include an unlocking position and a locking position in the moving process, wherein when the clamping member 3 moves to the unlocking position, the first clamping groove 23 is located at a position completely separated from the first clamping block 320, and at this time, the second connecting member 2 can be pulled out; when the clamping member 3 moves to the locking position, the first clamping block 320 is fixedly clamped with the first clamping groove 23, and thus the first connecting member 1 is fixedly connected with the second connecting member 2. The position switching of the clamping piece 3 can be realized by pressing the operating part 31, when the operating part 31 is pressed, the clamping piece 3 can integrally move upwards and move to the unlocking position, after the clamping piece 3 is located at the unlocking position, the clamping piece 3 presses the rebounding device, and in this state, the clamping column 2 can be freely inserted into or separated from the clamping cavity; and after the operating part 31 is released, the rebounding device is released and drives the clamping piece 3 to rebound to the locking position, and the clamping column 21 is fixedly connected with the clamping piece 3 at the locking position.
