By setting a limiting mechanism, the user passes the cable through the inside of the give way groove 202, so that the cable enters the inside of the slide groove 201. At this time, the pushing shell 204 is moved downward, so that the first limiting clip 203 squeezes the cable until the bottom of the cable contacts the second limiting clip 205, and squeezes the second limiting clip 205, so that the first spring 206 is squeezed. After reaching the preset position, the pushing shell 204 is positioned. At this time, the cable and the give way groove 202 are intertwined, so that the cable is limited. Compared with the prior art, the user does not have to spend a lot of energy on passing the cable between the first limiting clip 203 and the second limiting clip 205, thereby improving the user's work efficiency.

[0027] Reference Figures 1-4 , a first limiting groove 207 is provided on the opposite side of the two slide grooves 201, and a limiting block 208 is fixedly installed on the side of the first limiting groove 207 of the first limiting clip 203 and the second limiting clip 205 close to the first limiting groove 207.

There are several positioning blocks 301. The positioning blocks 301 are fixedly mounted on the left and right sides of the connecting rod 209. The connecting plates 210 on each side are divided into two rows and are arranged in a linear array. A moving cavity 302 is provided on the side of the push shell 204 close to the connecting rod 209. The internal sliding sleeve of the moving cavity 302 is provided with a wedge block 303. The shape of the bottom of the wedge block 303 is set to be inclined, and the top of the wedge block 303 is provided with a The changing groove 304 is shaped as an inclined shape, the internal sliding sleeve of the push shell 204 is provided with a moving rod 305, the bottom shape of the moving rod 305 is set to an inclined shape, the top of the moving rod 305 is fixedly installed with a pushing plate 306, the inner wall of the moving cavity 302 is fixedly installed with a second spring 307, the second spring 307 and the wedge block 303 are fixedly connected, the surface of the moving rod 305 is fixedly provided with a return plate 308, the bottom of the return plate 308 is fixedly installed with a third spring 309, the third spring 30 The other end of 9 is fixedly connected to the top of the push shell 204. By setting a positioning mechanism, when the user moves the push shell 204 downward, the shape of the bottom of the wedge block 303 is set to be inclined, so that the wedge block 303 is squeezed by the positioning block 301 and retracted into the interior of the moving cavity 302 until the wedge block 303 and the positioning block 301 intersect. The rebound force of the second spring 307 causes the wedge block 303 to pop out, and this is repeated until the push shell 204 drives the first limiting clip 203 to reach the preset position. At this time, The top of the wedge block 303 abuts the bottom of the positioning block 301, thereby locking the position of the wedge block 303 and the push shell 204. When the cable needs to be loosened, the user moves the push plate 306 downward, so that the moving rod 305 squeezes the inner wall of the changing groove 304. Since the inclined part of the bottom of the moving rod 305 cooperates with the inclined part of the changing groove 304, the wedge block 303 retracts into the interior of the moving cavity 302, unlocking the position of the push shell 204, so that the cable can be easily loosened.
