The T-shaped or Y-shaped connecting seat has three arms: the first arm, the second arm and the third arm; the first arm is connected to the motor, the driving wheel is connected to the output end of the motor, and the driven wheel is set on At the end of the second arm, the tensioning wheel is arranged at the end of the third arm; the driving wheel, the driven wheel and the tensioning wheel are connected through synchronous abrasive belt transmission;

The second handle is fixed on the connection base, and the first handle is fixed on the connection base or the motor.

The first arm is connected with the motor shield through the motor connecting seat.

The motor is a DC motor, and the motor is connected to the power box through a power cord.

The power cord is introduced from the end of the first handle.

Inside the power box are circuit boards for overvoltage, undervoltage, overtemperature, overload, overcurrent and short circuit protection.

There is a charging interface on the power box, and a 10-core socket on the power box as the power output interface.

The third arm is a telescopic arm, and a tension spring is arranged on the third arm.

The second handle is fixed to the end of the second arm.

The motor is fixed in the motor protective cover.

A fan is also arranged in the motor protective cover.

Beneficial effect

The portable cable insulation grinding machine of the utility model provides a convenient, fast and labor-saving cable insulation polishing tool. The third support arm is designed as a telescopic type, which can better tension the synchronous abrasive belt and prevent the synchronous abrasive belt from falling off the wheel. come out. The utility model is designed with two handles, which is convenient for users to hold. In addition, the use of rechargeable lithium batteries and DC motors facilitates on-site use during construction.
