Detailed ways

In order to deepen the understanding and recognition of the utility model, the utility model will be further described and introduced below in conjunction with the accompanying drawings.

Embodiment 1: As shown in Figure 1, a socket for preventing plug loosening includes a liner 1, a panel 2, a clamping piece 4, a spring 5, a joystick 3, a socket 6 and a base 7, on the liner 1 There is a square through hole in the middle part of the through hole, and a square groove is set around the through hole, and the panel 2 is mutually connected with the lining plate 1 through the square through hole and the groove on the lining plate 1. snap together. The top of the panel 2 is provided with a pin hole 21 and a joystick button jack 22, and a pair of side surfaces of the bottom of the panel 2 are provided with buckles 23 and mounting holes 24, and the buckles 23 are used to use the socket as A single module is fixedly installed on the socket sleeve with the installation card slot, so as to facilitate socket expansion according to actual needs. The base 7 is provided with a socket mounting groove 72 and a mounting protrusion 71, and the mounting protrusion 71 on the base 7 is used in conjunction with the mounting hole 24 on the panel 2, so that the panel 2 and The connection between the bases 7 is firm, ensuring that the panel 2 wraps the base 7 as a whole. The socket 6 is made of metal copper, and it is fixedly installed in the socket mounting groove 72 . The joystick 3 includes a square column and a button column 31, the square column is provided with a square groove 32 and a spring slot 33, the spring 5 is installed in the spring slot 33, and the clamping One end of the piece 4 is snapped into the square groove 32, and the other end is set on the rib at the ground hole end of the panel 2 so that the clamping piece 4 is placed on an inclined plane in the panel, which is beneficial for locking and insertion The latch in the latch hole 21. The clamping piece 4 is provided with a square through hole and a rectangular through hole, the size of the square through hole is smaller than the size of the rectangular through hole, and the size of the rectangular through hole is consistent with the size of the pin hole ; Use pins, keys or screws to fix the clamping piece 4 on the square groove 32 on the square column of the joystick 3 through the square through hole. Preferably, a pin is used to fix the clamping piece 4 on the operating rod 3 .

Embodiment 2: As shown in Figure 1, as an improvement of the present utility model, the square column of the joystick 3 and the button column 31 are connected together to form a "U" shape, and the height of the button column is greater than The height of the square column, the top of the button column is the joystick button.
