[0034] The working principle and usage process of this utility model: When using this utility model, in the process of railway construction, when it is necessary to connect long steel bars with straight threaded connectors, the steel bars need to be positioned and installed first. The steel bars are placed inside the positioning groove 45, and then the threaded rod 42 is rotated along the bearing 43 so that the movable rod 41 moves inside the positioning seat 44. At the same time, the clamping block 46 can clamp the steel bars to ensure the convenience and stability of steel bar installation. Then, the drive motor 7 is started to drive the steel bars to rotate, and the straight threaded connector is tightened to the corresponding threaded end of the steel bar to complete the installation. This improves the convenience of straight threaded connector installation, saves manpower, and improves work efficiency.

[0035] When the drive motor 7 is working for a long time, the cooling fan 14 can be turned on to draw in air. The air is filtered through the grille filter 16 and blown towards the drive motor 7, and then discharged through the heat dissipation slots of the side plate 8.
