Problems solved by technology
However, in the existing technology, due to the long power supply line of the hand-held grinder, it is extremely difficult to be retracted and easily affected by external factors such as trampling and dragging, so that the skin of the power supply line is damaged, resulting in a decrease in service life. In addition, due to There are many grinding machines used at the same time in the processing plant, so the reasonable setting of them is an important guarantee for reducing the floor space and ensuring the safety of electricity use.

A handheld polishing device comprises a installation box and a plurality of winding discs, hole grooves are formed in the centers of the winding discs, a cavity is formed in the installation box, and a first power device is fixedly mounted on the bottom wall of the cavity; the first power device is connected to a rotary column, and the upper end of the rotary column penetrates into the hole groove and is rotatably mounted in the top wall of the cavity; connecting rings are correspondingly arranged at the upper end and the lower end of each winding disc, and annulus face grooves matched with the connecting rings are formed in the end wall of the cavity; the connecting rings are rotatably mounted in the annulus grooves correspondingly, and port grooves are formed in the outer side of the installation box; and electric wires are wound on the winding discs, polishing machines are fixedly connected with the tail ends of the electric wires, the polishing machines are arranged in the port grooves, and a plurality of pipe control devices matched with the winding discs are vertically arranged in the rotary column.
Description
technical field [0001] The invention relates to the technical field of workpiece grinding, in particular to a hand-held grinding device. Background technique [0002] In some workpiece processing factories, grinding devices are often used to polish and polish the surface of workpieces to increase smoothness. Hand-held grinding machines are widely used because of their small size, high speed, good stability, single-handed operation, not easy to fatigue, and fine-grained workpieces. However, in the existing technology, due to the long power supply line of the hand-held grinder, it is extremely difficult to be retracted and easily affected by external factors such as trampling and dragging, so that the skin of the power supply line is damaged, resulting in a decrease in service life. In addition, due to There are many grinding machines used at the same time in the processing plant, so the reasonable setting of them is an important guarantee for reducing the floor space and ens...
