[0002] Steel is a strip steel with a certain cross-sectional shape and size. It is one of the four major types of steel (plate, tube, profile, wire). According to the cross-sectional shape, steel is divided into simple cross-sectional steel and complex cross-sectional steel (special-shaped steel). The former refers to square steel, round steel, flat steel, angle steel, hexagonal steel, etc.; the latter refers to I-beam, channel steel, rail, window frame steel, curved steel, etc., which are widely used in life and production.

[0003] The shortcomings of the existing technology: In the actual operation process, it is often necessary to connect and combine the steel sections so that their length can meet the actual needs.

[0011] Technical effects and advantages of the utility model:

[0012] The utility model is convenient for connecting the steel sections by providing a limiting ring, an insert pipe and a fixing sleeve, and the steel sections can be disassembled after connection. When connecting, the steel sections are inserted into the insert pipe, and bolts are used to screw into the steel sections through fixing grooves so that the steel sections cannot rotate in the insert pipe. Then, the steel sections are held, and the limiting ring and the fixing sleeve are rotated. The top block can contact the pressure block through rotation. Since the rounded corners at both ends of the top block are provided and the top block has a certain flexibility, the top block can be deformed by extrusion, so that it can be stacked with the pressure block. When the deformation occurs, the contact between the anti-skid pad and the surface of the steel sections is tighter, so that the steel sections can be The fixation is more secure, and the plug column rotates with the limit ring when it rotates. The plug column can be aligned with the slot through continuous rotation, and the plug column can be inserted into the slot under the action of the spring, thereby limiting the limit ring and the fixing sleeve so that they cannot rotate, thereby ensuring the stability of the steel after fixation. When disassembly is required, just pull the pull block outward to allow the plug column to leave the slot, and by rotating the limit ring and the fixing sleeve in the opposite direction, the top block can be separated from the pressure block, thereby making the connection between the anti-slip pad and the steel looser. Finally, unscrew the bolts fixed between the steel and the fixing tube to remove the steel, which is convenient for repeated use. BRIEF DESCRIPTION OF THE DRAWINGS

The rounded corner setting and the memory metal material with a certain flexibility allow it to be deformed more easily and stacked with the pressure block 104, so that the anti-slip pad 304 can be tightly attached to the surface of the steel section, and the top block 303 can return to its original shape when not in use, so that it can be used again.

[0023] Furthermore, the anti-skid pad 304 is made of rubber, and its surface is rough, so that it can ensure that the steel section is fixed more firmly.

[0024] Furthermore, the limiting ring 4 includes a ring body 401, the interior of the ring body 401 is provided with a movable groove 406, the interior of the ring body 401 is movably connected with a plug post 403, the top of the plug post 403 is fixedly connected with a pull block 402, the outer side of the plug post 403 is fixedly connected with a limiting block 405, a spring 404 is fixedly connected between the ring body 401 and the limiting block 405, and the plug post 403 and the limiting block 405 can move in the movable groove 406.
