Background
The sleeve is used for realizing the continuous connection of two sections of steel bars, is a new steel bar connection process after a binding process and a welding process, has the advantages of high joint strength, high connection speed, steel material saving and the like, and is widely adopted by the building construction industry. At present, a wrench or a pipe wrench or other hand tools are usually used to screw the splicing sleeve or the steel bar, so that two sections of steel bars are screwed into the sleeve to achieve connection. Although the method is simple, the labor intensity is high and the efficiency is low.
For this reason, "CN 208960871U" and "CN 210189680U" disclose two portable screw steel quick connection devices with different structures, respectively; although the labor intensity is reduced and the steel bar splicing efficiency is improved, the above patent can only realize splicing of two horizontal steel bars, and is not suitable for connection of two vertical steel bar net cages (the lower steel bar net cage is pre-buried in the concrete, and the upper steel bar net cage is erected above the lower steel bar net cage through a hoisting machine), so that a manual screwing mode is required to be used. However, because the density of the steel bars of the mesh cage is large, the rotation angle of the wrench is small, the efficiency is low, the physical consumption is large, and the requirement on the technical skill of an operator is high.

Detailed Description
The invention is further described with reference to the following figures and specific examples.
As shown in FIGS. 1-4: the invention is composed of a clamping device and an electric mechanism for driving the clamping device to rotate. The clamping device is a gear-shaped structure formed by the cohesion of a first half gear 1 and a second half gear 10 through a hinge mechanism and a locking mechanism; the electric mechanism is composed of a motor 6 which is fixed on a speed reducer 8 and connected with the input end of the speed reducer, a driving gear 3 which is fixed on the speed reducer 8 through a support 4 and connected with the output end of the speed reducer, and a handle 7 which is fixed on the support 4 and the motor 6, wherein the driving gear 3 can be meshed with the clamping device.
The hinge mechanism in the technical scheme is composed of a mortise 17 arranged on the left combining surface of the first half gear 1, a tenon 15 connected with the left combining surface of the second half gear 10 into a whole, and a pin 16 penetrating through the mortise 17 and the tenon 15 and pivoted with the first half gear 1 and the second half gear 10. In order to avoid interference between the gear teeth of the first half gear 1 and the gear teeth of the second half gear 10 in the process of rotating around the pin shaft 16, at least two gear teeth on the first half gear 1 near the left combining surface intersect with the top surface and the bottom surface of the mortise 17; correspondingly, at least two teeth are distributed on the outer cylindrical surface of the pin 15. The locking mechanism in the above technical solution is composed of an ear seat 2 fixed on the first half gear 1 and having a screw hole (not marked in the figure), and a stud 18 fixed on the second half gear 10 through a support 14, and the stud is adapted to the screw hole.
In order to prevent the drive gear 3 from disengaging from the clamping device during the screwing of the coupling sleeve 11, a hook plate 9 is fastened to the carrier 4, which hook plate is located below the drive gear 3.
In order to facilitate the quick locking of the first and second half- gears 1, 10, a handle 12 is fixed to the stud 18.
For the convenience of operation, a handle 5 can be fixed on the motor 6.
In order to avoid the slip between the clamping device and the adapter sleeve 11, anti-slip threads are distributed on the inner circumferential surface of the first half-gear 1 and the inner circumferential surface of the second half-gear 10.
The working principle is as follows:
in use, the sleeves 11 are screwed into the lower ends of the bars 13 of the upper section of the reinforcement cage (not shown) to align the lower ends of the sleeves 11 with the upper ends of the bars 13 of the lower section of the reinforcement cage (not shown). The first half gear 1 and the second half gear 10 are used for embracing the splicing sleeve 11, and the first half gear 1 and the second half gear 10 are locked by a locking mechanism to form a gear-shaped structure. The hook plate 9 hooks the steel bar 13 and the driving gear 3 is meshed with the clamping device; starting the motor 6, the driving gear 3 can drive the splicing sleeve 11 to rotate through the clamping device, so that the splicing sleeve 11 gradually exits from the lower end of the upper section of the reinforcing steel bar 13 and is gradually screwed into the upper end of the lower section of the reinforcing steel bar 13 until the butt joint of the upper section of the reinforcing steel bar 13 and the lower section of the reinforcing steel bar 13 is approximately positioned at the middle section of the splicing sleeve 11, the motor 6 can be stopped, the electric mechanism is moved away from the reinforcing steel bar 13, the clamping device is taken down, and the splicing of the two sections of the reinforcing steel bars is completed.
