Abstract

The invention discloses a speed regulating mechanism of an electric bench grinder. The speed regulating mechanism of the electric bench grinder has the speed regulating function and comprises a motor end cover and a motor shaft, wherein a photosensitive piece is arranged on the motor shaft, a plurality of photosensitive holes are formed in the photosensitive piece, a photoreceptor which is matched with the photosensitive piece is arranged on the motor end cover, and the photoreceptor is connected with a control panel through a circuit board. The speed regulating mechanism of the electric bench grinder has the advantages that the speed regulating function is achieved, and using is extremely convenient.

Description

technical field [0001] The invention relates to a grinder, in particular to an electric desktop grinder speed regulating mechanism. Background technique [0002] Electric desktop grinder is a commonly used grinding tool, used to grind some hard workpieces, such as: knives, drills, etc. The structure of the existing electric desktop grinder mainly includes: a base, a switch panel arranged on the base, a power source of the fuselage, a switch arranged on the switch panel for controlling the power source of the fuselage, respectively arranged at both ends of the power source of the fuselage and Grinding discs driven by the power source of the fuselage. The existing electric desktop grinder does not have the function of speed regulation, and it is very inconvenient to use. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a speed regulating mechanism of an electric desktop grinder with a speed regulating function. ...
