Embodiment Construction

[0013] The embodiment of the present invention is shown in the accompanying drawings: the operator holds the crank handle 7, and at this moment, the shift handle 6 can be placed in a fast position, as shown in the attached Figure 4 Move the gear handle 6 upward as shown, and then rotate the fastening bolt (nut) clockwise to obtain a fast screw-in speed. Move the main transmission shaft 10 upwards, the upper transmission gear 5 on the main transmission shaft 10 is separated from the two upper transmission teeth 4 on the two auxiliary transmission shafts 12, and the main transmission shaft clutch block 11 on the main transmission shaft 10 and the casing drive The auxiliary transmission shaft clutch block 13 on the shaft 8 is combined, and the main transmission shaft 10 drives the casing 1 to rotate through the casing transmission shaft 8 to realize fast rotation.

[0014] When the rotating part is quickly sent to the pre-tightening level, the torque of the bolt (nut) increases,...
