Wall surface grinding machine for decoration

Abstract

The invention discloses a wall surface grinding machine for decoration. The wall surface grinding machine structurally comprises a handle, a carbon brush motor, a guide pipe, a machine head shell, a grinding disc and a connecting device, the grinding disc is arranged in the front end of the machine head shell and connected with the carbon brush motor through the connecting device arranged in the machine head shell, and the connecting device is composed of a main shaft, a transmission shaft, a compression sleeve and a bearing. The main shaft is connected to the carbon brush motor, the left end of the transmission shaft is perpendicularly fixed to the grinding disc, the left end of the compression sleeve is connected to the outer end of the bearing, and the end of the compression sleeve is fixed to the inner wall of the machine head shell. According to the wall surface grinding machine for decoration, by using the connecting device, the transmission shaft and the main shaft are separated by the compression sleeve, decoration workers press down the machine head shell, the main shaft is connected with the transmission shaft, and the grinding disc rotates to perform wall surface grinding operation; and when the decoration workers are tired or the machine accidentally slips out of the hand, the compression sleeve provides elastic force to eject the grinding disc and the transmission shaft out, the main shaft cannot continuously drive the grinding disc to operate, and the decoration workers are prevented from being driven by friction of the grinding disc to cause further injury.

Description

technical field [0001] The invention relates to the field of decoration equipment, in particular to a wall grinder for decoration. Background technique [0002] Decoration workers often hold electric grinding equipment and grind the building wall or cement floor through the rotation of the grinding disc driven by the carbon brush motor to polish and level the wall so that the flatness of the wall meets the construction requirements; [0003] However, when the rotating grinding disc first touches the wall, the grinding disc will rub against the wall and run to the tangential direction of rotation in an instant. You need to hold the handle at all times and overcome the friction generated by the grinding disc on the wall. When your hands are tired Hands-off often occur, which not only easily causes equipment damage, but also leads to safety hazards for decoration workers. Contents of the invention [0004] In view of the above problems, the present invention provides a wall ...
