Detailed Description
The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:
as shown in the accompanying drawings, a reducing mechanism of an electric tightening machine comprises a mounting plate 5, wherein the mounting plate 5 is a circular plate, and the mounting plate 5 is arranged in a fixing plate 6. The novel electric tightening machine is characterized in that three cylinders 2 are uniformly arranged on one side of the mounting plate 5 along the same circumference, the head portions of the cylinder rods of the three cylinders 2 face the center of the circumference, the cylinder body of each cylinder 2 is fixedly mounted on the mounting plate 5 through a mounting seat 1 through a screw, the head portion of the cylinder rod of each cylinder 2 is connected with a connecting sleeve 5, a tightening shaft connecting hole 9 is formed in the front end of each connecting sleeve 5, and the tightening shaft connecting hole 9 is used for being connected with a tightening shaft of the electric tightening machine in a matched mode.
