Among them, the support column 1 is threadedly provided with a positioning screw sleeve 8, and the setting of the positioning screw sleeve 8 can limit the top of the support beam 3, further ensuring the stability of the support beam 3 after safety.

[0018] Furthermore, the positioning member includes a guide sleeve 9 arranged at the bottom of the supporting beam 3, and a guide portion with adjustable length is movably arranged in the guide sleeve 9, wherein the top end of the guide portion movably passes through the top end of the supporting beam 3, and the bottom end of the guide portion movably passes through the bottom end of the guide sleeve 9, and the clamping plate 4 is arranged at the upper and lower ends of the guide portion. When in use, the cable is placed in the upper clamping plate 4, and the guide portion is driven to move downward under the action of the gravity of the cable, and the clamping plate 4 below the guide portion will be clamped on the cable on the lower supporting beam 3 to achieve fixed positioning of the cable. Among them, the guide portion is preferably elastically arranged in the guide sleeve 9 to buffer the force of the cable acting on the guide portion during use, and ensure that the guide portion stably moves downward under the action of external force to drive the lower clamping plate 4 to act on the lower cable.

[0019] Specifically, the guide portion includes a guide rod 10, the top end of the guide rod 10 is movably extended from the support beam 3, and is connected to a clamping plate 4. The guide rod 10 is movably sleeved in a sleeve 11, and a locking bolt 12 for positioning the guide rod 10 is provided on the sleeve 11. An adjustment slot 13 for adjusting the locking bolt 12 is provided at the front end of the guide sleeve 9. By adjusting the insertion length of the guide rod 10 in the sleeve 11, the overall length of the entire positioning clamp can be adjusted to meet different usage requirements; the sleeve 11 is elastically arranged in the guide sleeve 9 by a spring 14; the clamping plates 4 are respectively arranged at the top of the guide rod 10 The sleeve 11 is connected to the guide sleeve 9 through the spring 14, which can not only play a buffering role when the cable is placed, but also can release the positioning connection between the locking bolt 12 and the guide rod 10 when the cable below the top needs to be adjusted, so that the sleeve 11 can move upward and reset under the restoring tension of the spring 14, thereby releasing the limit operation on the top of the cable below it, and facilitating the adjustment of the cable at this position; to avoid the cumbersome operation of adjusting all cables at all heights when the cable needs to be adjusted, so as to improve the convenience of operation. Preferably, a guide slide bar 15 is provided on the inner wall of the guide sleeve 9 through the mounting plate, and a guide slider 16 slidably connected to the guide slide bar 15 is provided on the outside of the sleeve 11, which can provide guidance for the up and down movement of the sleeve 11 and the guide rod 10; the guide slider 16 is provided with a spring 14 sleeved on the outside of the guide slide bar 15, and the two ends of the spring 14 are respectively fixedly connected to the guide slider 16 and the mounting plate above; in the working state, the spring 14 is in a stretched state.

[0020] Both sides of the guide sleeve 9 are provided with positioning holes 17 in the vertical direction, and the positioning holes 17 penetrate the guide sleeve 9; the sleeve 11 is provided with a positioning spring piece 18, and the bottom of the positioning spring piece 18 is provided with an elastic protrusion 19 that can be extended into the positioning hole 17 for positioning. The arrangement of the positioning spring piece 18 and the elastic protrusion 19 can realize the positioning operation of the sleeve 11 by extending the elastic protrusion 19 in the corresponding positioning hole 17 when the guide rod 10 is forced to move downward, and assist in fixing its position to ensure the stability of the clamping plate 4 in the process of limiting and fixing the cable; in addition, the inner wall of the guide sleeve 9 to the positioning hole 17 is arranged to be an eight-shaped structure that contracts from the outside to the positioning hole 17, that is, each positioning hole 17 is located on one side of the inner wall of the guide sleeve 9. The structure is extended outward through an inclined surface, which is convenient for the elastic protrusion 19 to extend from the positioning hole 17 to the outside. In and out of the hole 17; in addition, in the present invention, an unlocking spring piece 20 is also provided at a position corresponding to the positioning hole 17 on the outside of the guide sleeve 9. In the initial state, the unlocking convex head end of the unlocking spring piece 20 is located below the positioning hole 17, and after the elastic protrusion 19 enters the positioning hole 17, it is located below it. When it is necessary to release the limit of the sleeve 11, the unlocking spring piece 20 is pressed inward, and the unlocking convex head at its bottom will push the elastic protrusion 19 out of the positioning hole 17, so that the limiting operation of the sleeve 11 can be released. The structure is simple, the operation is easy, and the practicability is strong.

[0021] During use of the present invention, the support column 1 is first installed at the specified position using the fixing plate 2; then the bottom support beam 3 is adjusted to be perpendicular to the support column 1, and the remaining support beams 3 are adjusted to be arranged perpendicular to the support beam 3 on one side of the support column 1 and the bottom; sufficient space is reserved for the placement of the bottom cable; then the cables are gradually installed in the corresponding clamping plates 4; as the cables are installed on the support beam 3 above the bottom, the sleeve 11 can be moved downward, driving the clamping plate 4 thereon to engage with the cable below, thereby completing the limit fixation of the cable, which greatly ensures the stability of the cable position. A specific distance is ensured between each cable so that they do not affect each other, thus eliminating the existence of interference. At the same time, it also avoids the phenomenon of cable connector displacement caused by cable displacement, thereby enhancing the practicality of the present invention. When it is necessary to adjust and repair the cables below the top, the locking bolt 12 on the sleeve 11 above the corresponding cable can be loosened, and under the restoring force of the spring 14, the sleeve 11 is driven to move up and away from the cable cover, so that the space at the cable is released and the limit of the cable is also released. There is no need to remove the clamping plates 4 on all cables, thereby improving the convenience of operation and enhancing the practicality of the present invention.
