The locking piece 92 moves upwards in the connecting channel 9111 until the locking piece 92 moves to a position corresponding to the clamping portion 9112, and then the locking piece 92 is rotationally locked on the clamping portion 9112, so that locking of the locking piece 92 on the lock seat 911 is achieved, and the structure is simple, reliable and convenient to achieve.

The holding portion 9112 is further provided with a guiding surface 91121, and the guiding surface 91121 is disposed obliquely upward or downward from the connection channel 9111, so that when the locking member 92 enters the connection channel 9111 to move to a position corresponding to the holding portion 9112 or leaves a position corresponding to the holding portion 9112 through the connection channel 9111, a certain offset error is allowed, and the accuracy of inserting the locking member 92 into the connection channel 9111 is increased.

The connection passage 9111 is matched in shape with the lock member 92 so that the lock member 92 moves in the vertical direction in the connection passage 9111 with high reliability.

The locking member 92 includes a T-shaped locking lever 921, the T-shaped locking lever 921 including a shaft body 9211, and at least one hooking portion 9212 extending outwardly from one end of the shaft body 9211, the locking member 92 being rotatably locked to a locking position of the lock housing 911 by the hooking portion 9212. The hooking portion 9212 rotates to lock the hooking portion 9212 at the locking position of the lock base even if the locking piece 92 is locked to the lock base 911. The relative positions of the shaft body 9211 and the hanging portion 9212 of the T-shaped lock rod 921 facilitate the restriction of the rotation of the hanging portion 9212 by the lock base 911 to lock the T-shaped lock rod 921 on the lock base 911. Meanwhile, by the relative position of the hooking portion 9212 and the shaft body 9211, the hooking portion 9212 is convenient to hold to rotate the T-shaped lock lever 921.
