The force applied by the locking member 45 may be controlled electronically or by other means. Specifically, referring to fig. 1, 16 and 17, the lock mechanism 4 includes a cam 46, the cam 46 rotates coaxially with the first rotation shaft 2, the cam 46 abuts against a position of the lock member 45 toward the first rotation shaft 2, and rotation of the first rotation shaft 2 enables a protrusion of the cam 46 to push the lock member 45 toward the second rotation shaft 3 to lock relative rotation of the link member 1 and the second rotation shaft 3. Thus, when the first rotating shaft 2 rotates, the first rotating shaft 2 drives the cam 46 to rotate, the cam 46 presses the locking piece 45, so that the cam 46 pushes the locking piece 45 towards the second rotating shaft 3, and further, the relative rotation of the connecting piece 1 and the second rotating shaft 3 can be locked.
It should be noted that, an end of the locking member 45 facing the cam 46 may be a smooth arc surface so as to be matched with the cam 46.
Further, in order to make it possible to move the locking member 45 away from the second rotation shaft 3 to unlock the rotation of the second rotation shaft 3, as shown in fig. 1 and 18, the locking mechanism 4 includes a restoring member 47, and the restoring member 47 is used to apply an elastic restoring force to the locking member 45 away from the first rotation shaft 2 to unlock the relative rotation of the connection member 1 and the second rotation shaft 3.
The restoring member 47 may be any elastic member that can provide restoring force, for example, the restoring member 47 is a spring, a shrapnel, or the like. Referring to fig. 1, 17 and 18, the restoring member 47 is a spring, and the number of the springs is two, and the two springs are respectively arranged at two sides of the extending direction of the locking member 45, so as to ensure uniform stress.
The engagement of the locking member 45 with the second rotating shaft 3 may be achieved by the following structure:
Referring to fig. 1, 17 and 19, the locking mechanism 4 includes a stopper groove 31 provided on the second rotation shaft 3, the stopper groove 31 being provided along the circumferential direction of the second rotation shaft 3; when the locking member 45 moves away from the second rotating shaft 3, the end of the locking member 45 is disengaged from the stopper groove 31 to unlock the relative rotation of the connecting member 1 and the second rotating shaft 3; when the locking member 45 moves toward the second rotating shaft 3, the end of the locking member 45 protrudes into and engages with the end surface of the stopper groove 31 to lock the relative rotation of the coupling member 1 and the second rotating shaft 3.
It should be noted that, since the end of the locking member 45 has two positions of locking and unlocking with respect to the second rotating shaft 3, the switching of the two positions is completed by the cooperation of the cam 46 and the restoring member 47. In order to facilitate the limiting and guiding of the locking member 45, referring to fig. 17, the end of the locking member 45 has a radial guiding portion 454, referring to fig. 19, a guiding convex ring 32 is further disposed above the stop groove 31 on the second rotating shaft 3, and when the end of the locking member 45 is matched and extended into the stop groove 31, the guiding convex ring 32 is matched with the guiding portion 454, so that the locking member 45 can be further limited, and the locking member 45 can slide along the stop groove 31 until reaching the end face of the stop groove 31.
In addition, referring to fig. 1 and 20, in order to limit and guide the movement of the locking member 45, two limiting members 13 are provided on the connecting member 1, and the locking member 45 is disposed in a gap between the two limiting members 13 and is limited by the two limiting members 13.

Of course, referring to fig. 21 and 25, the connector 1 (the connecting piece in the middle position shown in the drawings) is provided with a relief hole 14, so that the stress section 452 can pass through.
In addition, referring to fig. 21 and 22, a stop collar 48 is provided at a position of the first shaft 2 corresponding to the locking member 45, and the stop collar 48 rotates coaxially with the first shaft 2, so that the locking member 45 is restricted from moving toward the first shaft 2, and the locking section 451 can be correctly engaged with the second shaft 3 when the locking member 45 rotates.
