[0002] The rebar sleeve connection technology is the most common rebar connection technology at present. As for the current rebar sleeve connection process, most of them adopt the rib stripping and rolling technology. The specific construction process is that several workers use pipe pliers to twist one end of the rebar into the rebar sleeve fixed at one end, and then twist the other end of the rebar into another rebar sleeve.

[0003] During the construction process, several workers use pipe clamps to twist one end of the steel bar into a steel bar sleeve fixed at one end, and then twist the other end of the steel bar into another steel bar sleeve. In this process, due to the defects of traditional technology, the steel bar will be severely twisted and bent during construction, which will affect the construction quality to a certain extent, and it will be time-consuming and labor-intensive, inconvenient and inefficient. On the other hand, during the manual construction process, problems such as "missed twisting" or "over-tightening" may occur due to the level of construction technology.

[0025] Reference Figure 2-Figure 3 , an outer wall of one side of the hand support 33 is provided with an indication mark, and the operation method is prompted by setting the indication mark. The inner circle of the auxiliary sleeve 38 is threadedly connected with a second threaded steel bar 39, and one end of the spring 34 away from the mounting plate 32 is fixedly connected to the inner wall of one side of the adjusting disk 31. There are a plurality of adjusting holes 36, and the plurality of adjusting holes 36 are respectively opened on the side outer wall of the threaded sleeve 2. The inner diameter of the adjusting hole 36 is adapted to the outer diameter of the limiting column 35.
