The driving mechanism 12 is disposed on the male body 11 and connected to the cylinder block 13, and the cylinder block 13 is driven by the driving mechanism 12 to move axially in the lock head 14, so as to adjust the relative position of the cylinder block 13 and the lock head 14, i.e. the mounting hole is aligned with the high position 131 or the second position 132. The female head 2 comprises a female head body 21 and a lock sleeve 22 arranged at the end part of the female head body 21, and an annular lock groove 23 matched with the steel ball 15 is arranged at the corresponding position of the inner wall of the lock sleeve 22. When the male head 1 is connected with the female head 2, the cylinder sliding block 13 is driven to be in an unlocking state through the driving mechanism 12, and then after the male head 1 is in butt joint with the female head 2, the driving mechanism drives the cylinder sliding block 13 to move to a locking state, so that the steel ball 15 protrudes out of the outer wall of the lock head and is clamped into the annular locking groove 23, and the male head 1 and the female head 2 are locked. In this embodiment, other sensors, such as a temperature sensor, may be used in combination, and when the temperature sensor detects that the ambient temperature is too high, the PLC controls the driving mechanism to drive the cylinder block 13 to move to the unlocking state, so that the male head 1 and the female head 2 can be separated.

Wherein the driving mechanism 12 may be a cylinder. Of course, in another embodiment, as shown in fig. 1 to 5, the driving mechanism 12 includes a servo motor 121, a screw 122, a connecting member 123 and a connecting rod 124, a guide hole is provided in the male head body 11, the connecting rod 124 is slidably disposed in the guide hole, one end of the connecting rod 124 is connected to the cylindrical sliding block 13, the other end of the connecting rod is connected to the connecting member 123, an adjusting screw hole is provided in the connecting member 123, the screw 122 is connected to the servo motor 121 and is in threaded engagement with the screw hole, and the servo motor 121 is used to drive the screw 122 to rotate, so that the connecting rod 124 pulls. The rotational motion of the servo motor 121 is converted into a linear motion. The link 124 and the guide hole are only axially movable and are not rotationally movable. Specifically, a guide groove is axially arranged in the guide hole, and a guide block is arranged on the side wall of the connecting rod.
