[0002] Bench drill is widely used due to its small size, convenient use and low cost. The main structure of bench drill includes motor, drill bit, machine base and the like. When working, the motor drives the drill shaft to rotate through transmission belt and belt pulley, and the drill shaft drives the drill bit to work, thereby drilling the workpiece.

[0003] The existing bench drill transmits power through belt pulley, and the size of the rotating speed is also adjusted by the belt pulley. At present, various bench drills of belt pulley type manufactured and sold on the domestic and foreign markets are all adjusted in rotating speed by tower type belt pulley. Its operation process is as follows: when it is necessary to change the rotating speed, the bench drill must be stopped, the belt cover is opened, the motor and the belt are loosened, and then the belt is moved from one groove to another groove to achieve the purpose of speed reduction or speed increase. After the belt is adjusted to the required rotating speed, the belt is tensioned, the motor cover is fixed, the belt cover is closed, and the speed adjustment operation is completed. Due to the limitation of structure, the operator needs to use large force to operate the operating rod in the whole process, which not only brings inconvenience to the operator, but also increases the labor intensity of the operator.
