[0026] A vertical tube 9 is fixedly provided on the upper side wall of the switch seat 1, a lamp tube 10 is slidably provided on the upper end of the wall of the vertical tube 9, a lamp cover 11 is fixedly provided on the upper end of the lamp tube 10, an LED lamp 12 is fixedly provided inside the lamp cover 11, the upper ends of the two wires 8 are electrically connected to the LED lamp 12, a threaded tube 13 is provided on the external thread of the lamp tube 10, an extrusion cover 14 is fixedly provided on the lower side wall of the threaded tube 13, symmetrical cavities are opened on the side wall of the lamp tube 10, and limiting mechanisms are provided inside the two cavities. The structure of the present application is simple. When the switch needs to be connected, it is only necessary to pull up the lamp tube 10 and rotate the threaded tube 13, so that the contact conductive sheet 7 at the lower end is driven to contact the U-shaped conductive sheets 5 at both ends through the internal wire 8, so as to realize the connection of the circuit. When the power supply needs to be disconnected, the limiting effect between the limiting mechanism and the vertical tube 9 is directly released, and the lamp tube 10 slides downward on the outside of the vertical tube 9, so that the contact conductive sheet 7 is separated from the U-shaped conductive sheet 5, and the power supply is turned off. There will be no accidental touch, and it is safer to use.

[0027] A bottom cover 15 is disposed at the lower end of the switch seat 1 , and symmetrical fixing bolts are threadedly disposed on the side wall of the bottom cover 15 . The bottom cover 15 is fixedly connected to the lower side walls of the two fixing blocks 2 through the symmetrical fixing bolts.

[0028] A fixing plate 16 is fixedly provided at the lower end of the vertical tube 9, and a first spring 17 is provided on the lower side wall of the fixing plate 16 outside the electric wire 8. The upper end of the first spring 17 is fixedly connected to the lower side wall of the fixing plate 16, and the lower end of the first spring 17 is fixedly connected to the upper side wall of the mounting plate 6. When the power supply needs to be disconnected, the contact conductive sheet 7 is separated from the U-shaped conductive sheet 5 under the action of the first spring 17, thereby disconnecting the power supply.

[0029] The inner wall of the threaded tube 13 is provided with an internal thread, and the outer wall of the lamp tube 10 is provided with an external thread. The internal thread of the threaded tube 13 and the external thread of the lamp tube 10 are matched.

[0030] The limiting mechanism includes a slider 18, which is slidably connected to the inner wall of the cavity, a plug rod 19 is fixedly provided on the right side wall of the slider 18, and sockets are provided on the upper ends of the left and right walls of the vertical pipe 9. The ends of the two plug rods 19 that are close to each other are plugged into the sockets. The ends of the two sliders 18 that are away from each other are fixedly provided with extrusion rods 20. The two extrusion rods 20 and the two plug rods 19 are slidably connected to the side wall of the cavity, and the ends of the two extrusion rods 20 that are away from each other are in contact with the inner wall of the extrusion cover 14. A second spring 21 is provided on the outer sleeve of the plug rod 19, one end of the second spring 21 is fixedly connected to the side wall of the slider 18, and the other end of the second spring 21 is fixedly connected to the inner wall of the cavity. When the threaded tube 10 moves up and the wire 8 is straightened, the threaded tube 10 and the vertical pipe 9 can be fixedly limited by the limiting mechanism.

[0031] The lower ends of the two electric wires 8 are in contact with the lower side wall of the contact conductive sheet 7 through the limit clamps.

[0032] Working principle:

[0033] When in use, the lamp tube 10 is moved upward, and the lamp tube 10 moves upward outside the vertical tube 9. The lamp tube 10 drives the internal wire 8 to move upward, thereby driving the lower installation piece 6 to move upward, so that the installation piece 6 drives the contact conductive sheets 7 at both ends to move upward and contact with the two U-shaped conductive sheets 5. At this time, by rotating the threaded tube 13, the threaded tube 13 drives the extrusion cover 14 at the lower end to rotate, and the interior of the extrusion cover 14 is set to an inclined surface, thereby squeezing the extrusion rod 20, and the extrusion rod 20 drives the slider 18 and the plug rod 19 of the side wall to move, and makes the plug rod 19 plug and fix with the socket, electrically connecting the conductive plug 4 with the socket, and then power is turned on, and the LED lamp 12 lights up. Conversely, when it is necessary to turn off the power, the threaded tube 13 is rotated upward, and the threaded tube 13 drives the extrusion cover 14 at the lower end to move upward. The plug rod 19 is separated from the socket under the action of the two second springs 21, and the lamp tube 10 is moved downward. At this time, the wire 8 moves downward, the contact conductive sheet 7 is separated from the U-shaped conductive sheet 5, and the power is turned off.
