Background

The electric pencil sharpener is a tool for driving a hob to rotate through a motor, so that the inserted pencil point is cut. With the continuous development of the electric pencil sharpener, the functions of the electric pencil sharpener are more and more improved. For example, the Chinese utility model patent "transmission delay assembly of pencil sharpener" applies for (patent): cn201921241964.x, a pneumatic pencil sharpener using a push-down operation is disclosed. In the using process of a user, as long as a pen is inserted into the floating knife rest, the floating knife rest is subjected to the force applied by the pen to move downwards to start a switch of the pencil sharpener, and the pencil sharpener starts to work. When the pen is sharpened, the pen touches the pen stopping block and drives the pen stopping block to move downwards, and the pen stopping block moves to drive the connecting rod to move. The connecting rod moves downwards to drive the time delay device to work, and the working time delay device contacts the stop switch to stop the motor.

In this type of actuation of the sharpener, it is necessary to involve a return element, typically a return buffer spring, which exerts a force on the floating blade carrier to return to the initial state by acting on the connecting rod. The knife rest in the existing pencil sharpener structure is usually made of metal materials, so that the weight of the knife rest is large, and the elastic coefficient is large when the reset buffer spring is correspondingly arranged. Therefore, the pencil block needs a large force to drive the connecting rod to move, the force needs to be provided by the sharpened pencil, and the pencil is easy to break in the force application process.
