[0002] Rebar connection refers to the connection method of rebar. There are four main connection methods of rebar: binding lap joint, mechanical connection, sleeve grouting connection and welding. Among them, the most widely used is the rebar sleeve. The two ends of the rebar are set to a threaded shape, and then the threaded sleeve is installed to connect the two ends of the rebar through threads. However, since most of the rebar sleeves are exposed to the outside, they are prone to rust and cannot be flexibly adjusted and assembled.

[0003] A search was conducted to find out the above-mentioned problems. Among the currently disclosed prior arts, there is a steel bar sleeve device proposed in publication number CN212583059U. The device is achieved by installing a middle sleeve between sleeve No. 1 and sleeve No. 2, and a forward-spinning threaded joint is installed at the bottom end of sleeve No. 1, and a reverse-spinning threaded joint is installed at the upper end of sleeve No. 2. Sleeve No. 1 and sleeve No. 2 are fixed by the middle sleeve, and the tightness can be adjusted by controlling the middle sleeve. An anti-rust coating is provided on the outside of the sleeve to prevent rust caused by long-term use of the sleeve. However, after the steel bars are fixedly connected, the steel bars exposed to the outside are subjected to more external forces, which can easily affect the fixation of the steel bars and may cause the steel bars to loosen.
