The installation cylinder 32 in the joint assembly 3 has a receiving cavity that can accommodate the sleeve 2; the sleeve 2 is placed in the receiving groove of the installation cylinder 32, and at this time the key groove 24 on the cylinder body 21 cooperates with the flat key 35 at the bottom of the receiving groove to play a role of positioning and transmitting torque. The ball 34 on the wall surface of the installation cylinder 32 is located in the raceway 38, which provides a sliding path for the ball 34. When the lock cylinder 33 slidingly sleeved on the outer wall of the installation cylinder 32 slides upward, the protrusion 36 on the inner wall of the lock cylinder 33 pushes the ball 34 to displace radially along the installation cylinder 32, so that it is clamped into the clamping groove 23 on the wall surface of the sleeve 2, thereby fixing the sleeve 2 on the installation cylinder 32.

Due to the cooperation of the flat key 35 and the key groove 24, the torque can be effectively transmitted to prevent the sleeve 2 from slipping in the installation cylinder 32.

[0048] When different models of sleeves 2 are needed to adapt to different models of screws, slide the lock cylinder 33 downward, compress the reset spring 37, and the ball 34 exits the clamping groove 23 under the action of the lock cylinder 33 and the reset spring 37. At this time, the sleeve 2 can be removed, and other models of sleeves 2 can be installed, and the above installation steps are repeated.

[0049] As described above, although the present application has been shown and described with respect to a certain preferred embodiments, it should be construed as limiting the present application itself. Various changes in form and details can be made therein without departing from the spirit and scope of the present application defined in the appended claims.
