The anti-off mechanism 4 is used to prevent the insert block from being separated from the mounting seat 3. A trigger mechanism 5 is installed, and the trigger mechanism 5 acts on the anti-off mechanism 4, and the trigger mechanism 5 is used to drive the anti-off mechanism 4 to separate from the plug.

In order to design an anti-off mechanism 4 with a simple structure, the anti-off mechanism 4 includes: an anti-off lever 41 and a first spring 42. The mounting base 3 is provided with a jack for inserting a plug. For the plug in the hole, the other end of the anti-loosening rod 41 is connected to the mounting base 3 through the first spring 42, and under the elastic force of the first spring 42, the anti-loosening rod 41 can be kept inserted into the plug. The end of the anti-off rod 41 stretching into the jack is a triangular block structure to form a guide surface on the anti-off rod 41, and the guide surface is used to extrude the anti-off rod 41 when the plug is inserted into the jack. In the inner wall of the jack, so that the plug is inserted into the jack to give way, avoiding the need to adjust the trigger mechanism 5 when the plug is inserted into the jack, which causes troublesome operation.

Since the first spring 42 does not forcibly hinder the disengagement of the anti-off rod 41 from the plug, any movement of the human body during use, due to inertia and other reasons, is likely to cause the anti-off rod 41 to move relative to the plug and cause the anti-off rod to 41 is disengaged from the plug, in order to avoid the anti-off rod 41 from losing its position-limiting effect on the plug due to inertia in one direction, the following design has been made: the anti-off mechanism 4 also includes: anti-self-off assembly 43, anti-self-off The component 43 is installed at the anti-off rod 41, and the anti-self-off component 43 is used to prevent the anti-off rod 41 from detaching from the plug.

In order to ensure that the subsequent adjustment of the anti-self-off component 43 is convenient, and to ensure that the anti-self-off component 43 can maintain the position preventing the anti-off rod 41 from disengaging from the plug, the following structure is made: the anti-self-off component 43 is connected by an elastic part and The anti-loosening rod 41 is connected, and under the elastic force of the elastic part, the anti-loosening assembly 43 can be kept in a position preventing the anti-loosening rod 41 from detaching from the plug.

In order to realize the adjustment of a manual operation assembly 51, the anti-loosening assembly 43 can firstly allow the anti-loosening rod 41 to disengage from the plug, and then the anti-loosening rod 41 can be disengaged from the plug, so the following trigger mechanism 5 is designed: The trigger mechanism 5 includes: a manual operation assembly 51, a first drive assembly 52 and a second drive assembly 53, the manual operation assembly 51 is installed on the mounting base 3, and the manual operation assembly 51 is connected with the first drive assembly 52 and the second drive assembly 53 , the second driving component 53 is used to drive the anti-snap off component 43 to allow the anti-loosening rod 41 to disengage from the plug, and the first driving component 52 is used to drive the anti-loosening rod 41 to disengage from the plug.

The self-off prevention component 43 can move relative to the anti-off rod 41 in a direction perpendicular to the anti-off rod 41 .

The anti-self-off component 43 includes: a hook block 431, a connecting block 432, a passive block 433 and a second spring 434.
