Abstract

The invention discloses a telescopic wall surface grinding machine, which comprises a hand-hold main pipe, a grinding head, a grinding head fixing base, a driving motor and a driving flexible shaft. The driving motor is arranged on the hand-hold main pipe; the grinding head is connected with the driving motor through the driving flexible shaft; the hand-hold main pipe consists of a front pipe and a rear pipe which are in telescopic connection, and the telescopic positions of the front pipe and the rear pipe are locked by a locking device. In the structure, the hand-hold main shaft is telescopic, so when the hand-hold main pipe is used, the length of the hand-hold main pipe can be adjusted according to actual requirements to facilitate the operation; and at the same time, when the wall surface grinding machine is packed for transportation, the aim for reducing the volume and the occupied space can be achieved by contracting the length of the hand-hold main pipe.

Description

A kind of telescopic wall surface grinding machine

Technical field:

The present invention relates to a kind of wall surface grinding machine whitewashing, lay paint on the wall, wall being polished and cleaned before the sticking wallpaper etc.

Background technology:

At present, wall surface grinding machine on the market mostly comprises hand-held supervisor, is installed in the motor on the hand-held supervisor and is installed in the sanding apparatus of handing supervisor's front end, during use, people are held in hand-held supervisor's rear end, because hand-held supervisor's length is longer, thereby can polish to higher metope, yet, when need to lower metope (for example being lower than the metope of people's height) when polish, owing to being subject to the restriction of hand-held supervisor's length, operating and just become very inconvenient.Simultaneously, hand supervisor's length so that sander is bulky, thereby make troubles and inconvenience also for people's packed and transported, be unfavorable for the control of cost.

In addition, the drive motors of existing wall surface grinding machine is installed in hand-held supervisor rear end, driving snake one end is connected with grinding head, the other end stretches in the hand-held supervisor and along hand-held supervisor's length direction and extends, in order to be connected with the drive motors of hand-held supervisor rear end, this structure not only so that driving snake will design is very long, has increased manufacturing cost, nor has been beneficial to the installation and removal of driving snake.

Summary of the invention:
