[0019] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] In this embodiment: when wiring, press the two buttons 11, the two buttons 11 drive the two slide bars 9 to slide relative to each other, and then drive the second sleeve 7 to rotate through the short column 10 and the spiral groove 8. When the short column 10 slides to the other end of the spiral groove 8, it just drives the second sleeve 7 to rotate 90°, and then drives the spherical block 4 to rotate 90° in the spherical groove 3, so that the second through hole 5 is connected with the first through hole 2. At this time, the two wires are respectively inserted into the second through hole 5 from the two ends of the shell 1, and the button 11 is released. The button 11 slides outward under the elastic force of the spring 12, and then drives the two slide bars 9 to slide outward. The slide bar 9 further drives the second sleeve 7 to rotate in the opposite direction through the short column 10 and the spiral groove 8, and then drives the spherical block 4 to rotate in the opposite direction, so that the wire is stuck between the inner walls of the first through hole 2 and the second through hole 5, thereby fixing the wire, and the wiring is fast and convenient, and the use effect is good.

[0023] As a technical optimization solution of the utility model, the outer walls of the two first sleeves 6 are fixedly connected with two symmetrically distributed slide rails 14 , and the inner walls of the two buttons 11 are provided with two slide grooves 13 matching the slide rails 14 .

[0024] In this embodiment, the button 11 and the slide rod 9 are limited by the slide rail 14 and the slide groove 13, so that the slide rod 9 can only slide but not rotate, thereby preventing the slide rod 9 from driving the spherical block 4 to rotate and lose the fixing effect.

[0025] As a technical optimization solution of the present invention, the number of turns of the spiral groove 8 is one quarter of a turn.

[0026] In this embodiment, by setting the number of turns of the spiral groove 8 to a quarter turn, the maximum rotation angle of the spherical block 4 is 90°.

[0027] As a technical optimization solution of the present invention, the spherical block 4 is made of metal.

[0028] In this embodiment, the spherical block 4 is made of metal, so that the conductive wire can conduct electricity after contacting the spherical block 4 .

[0029] As a technical optimization solution of the present utility model, the housing 1 is made of plastic.

[0030] In this embodiment, the housing 1 is made of plastic material to prevent the housing 1 from conducting electricity.

[0031] As a technical optimization solution of the present invention, the spiral directions of the spiral grooves 8 on the left and right sides are opposite.

[0032] In this embodiment, by setting the spiral directions of the spiral grooves 8 on the left and right sides to be opposite, it is convenient to drive the two second sleeves 7 to rotate in the same direction when the two buttons 11 slide relative to each other when pressed.

[0033] The working principle and use process of the utility model are as follows: when wiring, the two buttons 11 are pressed, and the two buttons 11 drive the two slide bars 9 to slide relative to each other, and then drive the second sleeve 7 to rotate through the short column 10 and the spiral groove 8. When the short column 10 slides to the other end of the spiral groove 8, it just drives the second sleeve 7 to rotate 90°, and then drives the spherical block 4 to rotate 90° in the spherical groove 3, so that the second through hole 5 is connected with the first through hole 2. At this time, the two wires are respectively inserted into the second through hole 5 from the two ends of the shell 1, and the button 11 is released. The button 11 slides outward under the elastic force of the spring 12, and then drives the two slide bars 9 to slide outward. The slide bar 9 further drives the second sleeve 7 to rotate in the opposite direction through the short column 10 and the spiral groove 8, and then drives the spherical block 4 to rotate in the opposite direction, so that the wire is stuck between the inner walls of the first through hole 2 and the second through hole 5, thereby fixing the wire, and the wiring is fast and convenient, and the use effect is good.

[0034] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
