The invention discloses a multi-angle internal corner deformed
abrasive paper frame. The multi-angle internal corner deformed
abrasive paper frame comprises a first bottom plate and a second bottom plate which are connected in a hinged mode; the movable ends of the first bottom plate and the second bottom plate are connected with telescopic plates in a hinged mode; the first bottom plate and the second bottom plate are covered with
abrasive paper, and the two ends of the abrasive paper are fixed to the telescopic plates; and the included angle between the first bottom plate and the second bottom plate is adjusted by adjusting the length of the telescopic plates. According to the multi-angle internal corner deformed abrasive paper frame, the purpose of changing the included angle between the first bottom plate and the second bottom plate is achieved by adjusting the length of the telescopic plates, and thus various angular dimensions of
grinding work of wall corner
putty can be handled;a
torque sensor is arranged in a power device, the threshold value of torque is set in a controller, thus when the numerical value of the
torque sensor is larger than the threshold value, the controller controls a motor to stop working, in this way, the value of the initial internal corner does not need to be measured, the
grinding steps are simplified, and the working efficiency is high; and themulti-angle internal corner deformed abrasive paper frame is simple in structure, small in size, low in weight, easy to use and convenient to operate.
