The high-efficiency rotationally adaptable threaded steel butt joint sleeve comprises a threaded butt joint sleeve. When a steel bar body and the threaded butt joint sleeve need to be connected, an alignment groove and an alignment block are aligned and clamped.

Then, it is only necessary to drive the telescopic rod and the steel bar body to rotate through a rotating drive mechanism, and spirally rotate the steel bar body into the connecting groove to complete the connection between the steel bar body and the threaded butt joint sleeve. Through the above design, the connection between the steel bar body and the threaded butt joint sleeve is more efficient and convenient.

According to claim 1, a high-efficiency rotationally adaptable threaded steel butt sleeve is characterized in that: A butt joint ring (24) is fixedly connected to the lower inner wall of the connecting groove, a trapezoidal ring (25) is fixedly connected to the upper end of the butt joint ring (24), a butt joint groove (27) is provided at the lower end of the steel bar body (1), an anti-slip groove (26) is provided on the upper inner wall of the butt joint groove (27), and the anti-slip groove (26) and the butt joint groove (27) are matched with the trapezoidal ring (25) and the butt joint ring (24) respectively.

3. The high-efficiency rotationally adaptable threaded steel butt sleeve according to claim 2 is characterized in that: A telescopic tube (33) is fixedly connected to an inner wall of one side of the placement groove (31), and the second spring (32) is sleeved on the circumferential surface of the telescopic tube (33).

4. A method for using a high-efficiency rotary adaptable threaded steel butt sleeve, characterized in that: The high-efficiency rotationally adaptable threaded steel butt sleeve described in claim 3 is used, comprising the following steps: S1: When the steel bar body (1) and the threaded butt sleeve (2) need to be rotationally threadedly connected, the alignment groove (28) provided at the lower end of the steel bar body (1) is aligned with the alignment block (34) and clamped, and then the stabilizing block (30) is pushed outward and clamped into the stabilizing groove (29) through the elastic expansion of the second spring (32), thereby completing the preliminary docking and calibration of the steel bar body (1) and the threaded butt sleeve (2); S2: After the calibration and docking are completed, the outer rotating sleeve (3) is rotated to allow the inner gear ring (22) fixedly connected to the inner wall of the outer rotating sleeve (3) to start meshing with the two third gears (19), and then the two third gears (19) are meshed with the second gear (18), driving the second gear (18), the installation groove (15) and the telescopic rod (16) to rotate, and at the same time, the alignment block (34) and the steel bar body (1) start to rotate, and the steel bar body (1) is screwed inward through the threads on the inner wall of the connection groove until the steel bar body (1) is completely threadedly connected to the connection groove, thereby completing the installation and connection of the steel bar body (1); S3: When it is inconvenient for a person to manually hold the outer rotating sleeve (3) to rotate, the plum blossom pin (6) is connected to the external driving device, and the external motor drives the external shaft (8) and the first gear (7) to rotate, thereby driving the outer gear ring (4) and the outer rotating sleeve (3) to rotate automatically, thereby automatically realizing the installation of the steel bar body (1).
