[0023] Specifically, Figure 1-Figure 4 As shown, a plurality of slide grooves 13 are symmetrically provided in the upper and lower parts of the fixed seat 1, and a slide plate 14 is slidably provided in the slide grooves 13, one end of the limit rod 8 extends into the adjacent slide groove 13 and is fixedly connected to the slide plate 14, a plurality of springs 15 are fixedly provided in an array on the side of the slide plate 14 away from the limit rod 8, a slide rod 16 is slidably embedded through the side of the slide plate 14 away from the limit rod 8, and both ends of the slide rod 16 are fixedly connected to the inner wall of one side adjacent to the slide groove 13. A plurality of grooves 17 are symmetrically provided at the top and bottom ends of the fixed seat 1, and a push rod 18 is slidably embedded in the groove 17, one end of the push rod 18 extends into the adjacent slide groove 13 and is fixedly connected to the slide plate 14, by pushing the push rod 18, the push rod 18 drives the slide plate 14 to slide on the slide rod 16, and the slide plate 14 will drive the limit rod 8 to move into the slide groove 13, and at the same time the slide plate 14 will squeeze the spring 15.

[0024] Specifically, Figure 1-Figure 4 As shown, a rotating groove 20 is annularly opened in the support 9, and a rotating block 21 is rotatably arranged in the rotating groove 20. One side of the rotating block 21 extends to the outside of the support 9 and is fixedly connected to the adjacent threaded sleeve 10. By rotating the screw sleeve 10, the threaded sleeve 10 drives the rotating block 21 to rotate in the rotating groove 20, and the rotating block 21 can support the threaded sleeve 10.

[0025] Example 2 Please refer to Figure 2 and Figure 3The difference between this embodiment and embodiment 1 is that: a spring 2 19 is slidably sleeved on the push rod located in the groove 17, one end of the spring 2 19 is fixedly connected to the side adjacent to the push rod 18, and the other end of the spring 2 19 is fixedly connected to the inner wall of the side adjacent to the groove 17.

The positioning rod 8 is realized by pushing the positioning rod 8, thereby the positioning rod 8 pushes the slide plate 14 to squeeze the spring 15. When the plug plate 6 is fully inserted into the slot 2 5, the spring 14 will push the slide plate 14 and the positioning rod 8 to reset, thereby the positioning rod 8 is inserted into the positioning groove 7, thereby completing the installation. When the vertical rod 2 needs to be replaced, at this time, by pushing the push rod 18, the push rod 18 drives the slide plate 14 to slide on the slide rod 16, and the slide plate 14 drives the positioning rod 8 to move into the slide groove 13, thereby separating the positioning rod 8 from the limiting groove 7, and at the same time rotating the corresponding threaded sleeve 10, thereby separating the threaded sleeve 10 from the stud 12, and then the vertical rod 2 can be taken out and replaced.
