Telescopic grinding machine convenient to use

Abstract

The invention discloses a telescopic grinding machine convenient to use. The telescopic grinding machine convenient to use comprises a shell. The shell comprises a handle, a shell body and a motor shell. The top of the handle is fixedly connected with the shell body. The end, away from the handle, of the shell body is fixedly connected with the motor shell. A motor is fixedly mounted in the motorshell. The end, away from the shell body, of the motor is fixedly connected with an output shaft. The side, penetrating through the motor shell, of the output shaft is fixedly connected with a coupling. The end, away from the output shaft, of the coupling is fixedly connected with a telescopic device. According to the telescopic grinding machine convenient to use, the telescopic device is arrangedso that the length of the grinding machine can be effectively adjusted, places such as the inner walls of certain pipelines, narrow areas or corner areas can be ground and polished, the polishing effect is good, and the telescopic grinding machine is convenient to use; and heat dissipation holes are formed so that heat in the motor shell can be effectively dissipated, and the situation that the motor is damaged due to the fact that the temperature is too high is prevented.

Description

technical field [0001] The invention relates to the technical field of hardware machinery, in particular to a convenient-to-use retractable grinding machine. Background technique [0002] Grinding and polishing machines are widely used in deburring and polishing of nail art, metal, wood, plastic, etc. At present, the commercially available grinding and polishing machines are not only too large, which affects their feel, but also have poor grinding effects. Fever, affecting the normal use of the machine, low work efficiency, lack of applicability, inconvenient use, unable to adjust and many other problems. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides an easy-to-use retractable grinder, which has the advantages of compactness, lightness, good grinding effect, convenient adjustment and good heat dissipation effect, and solves the problem of excessive volume, poor grindin...
