The working principle and the using method of the double-hole pencil sharpener of the embodiment are as follows.

In this embodiment, a contact type micro switch (corresponding to the first switch 5) with 3 connection terminals is used. When the touch-type microswitch is installed, the cathode of the motor is connected with the universal end C end 52 (see fig. 5) of the touch-type microswitch, the anode of the motor is connected with the cathode of a dry battery (not shown in the figure), the anode of the dry battery is connected with one pin of the key-type switch (corresponding to the second switch 8), and the other pin of the key-type switch is connected with the normally open end NO of the touch-type microswitch.

When the pencil is not needed to be cut, the push button 18 covers the first pen inserting hole 11 with a larger size, so that the sliding block 2 is prevented from triggering the first switch 5 due to the fact that the finger of a child stretches into the first pen inserting hole 11, and the first cutting assembly 3 is driven to rotate after the motor is started to cause injury.

In a state that the pencil is not inserted into the first and second inserting holes 11 and 12, the first end 211 of the sliding block 2 covers at least a part of the first inserting hole 11, and the second end 212 of the sliding block 2 covers at least a part of the second inserting hole 12.

When a pencil with a larger size needs to be cut, the push button 18 above the first pencil insertion hole 11 is slid to expose the first pencil insertion hole 11, when the pencil is inserted into the first pencil insertion hole 11, the pencil acts on the first end 211 of the sliding block 2 and drives the sliding block 2 to slide towards the second pencil insertion hole 12 (see fig. 4, at this time, the pencil pushes the sliding block 2 to move towards the right), the first trigger part 22 triggers the action site 51 of the first switch 5 to start the motor, so that the first cutting component 3 is driven to cut the pencil, and the first spring 6 is squeezed;

after the pencil is pulled out of the first pencil inserting hole 11, the sliding block 2 is pushed to move leftwards through the elastic force of the first spring 6 and the connecting part 24 of the sliding block 2, so that the sliding block 2 is restored to the initial position; when the slider 2 moves leftward, the first trigger 22 of the slider 2 is disengaged from the operating point 51 of the first switch 5, and the first switch 5 returns to the state of opening the circuit.

When a pencil with a smaller size needs to be cut, the pencil is inserted into the second smaller insertion hole 12, the pencil acts on the second end 212 of the sliding block 2 (see fig. 4, at this time, the pencil pushes the sliding block 2 to move leftward) and drives the sliding block 2 to slide toward the first insertion hole 11, the second trigger part 23 triggers the action site 51 of the first switch 5 to start the motor, so that the second cutting assembly 4 is driven to cut the pencil, and the second spring 7 is squeezed;

after the pencil is pulled out of the second pencil inserting hole 12, the sliding block 2 is pushed to move rightwards through the elastic force of the second spring 7 and the connecting part 24 of the sliding block 2, so that the sliding block 2 is restored to the initial position; when the slider 2 moves to the right, the second trigger 23 of the slider 2 is disengaged from the action point of the first switch 5, and the first switch 5 returns to the state of breaking the circuit.

When the sweeps need to be poured, the sweeps cover 17 is opened, the trigger end 171 of the sweeps cover 17 is far away from the second switch 8 at the moment to cut off the electric circuit, the motor stops running at the moment, the corresponding cutting assembly stops rotating, and therefore the electric circuit is cut off when the sweeps cover 17 is opened by a user, the situation that the electric circuit is not cut off and the user is injured by the rotating cutting assembly is avoided, and the safety is high.

the sliding block (2) can slide along the connecting line direction of the first pen inserting hole (11) and the second pen inserting hole (12), and a body (21) of the sliding block (2) is provided with a first end (211) and a second end (212) along the connecting line direction of the first pen inserting hole (11) and the second pen inserting hole (12);

the cutting assembly comprises a first cutting assembly (3), a second cutting assembly (4) and a motor; the first cutting assembly (3) is rotatably arranged in the shell (1) and communicated with the first pen inserting hole (11) and is used for cutting a pencil inserted into the first pen inserting hole (11); the second cutting assembly (4) is rotatably arranged in the shell (1), is communicated with the second pen inserting hole (12) and is used for cutting a pencil inserted into the second pen inserting hole (12); the motor is arranged in the shell (1) and is used for driving the first cutting assembly (3) or/and the second cutting assembly (4) in the shell (1) to rotate so as to cut a pencil;

when the pencil is not inserted into the first pen inserting hole (11) and the second pen inserting hole (12), the first end (211) of the sliding block (2) covers at least part of the first pen inserting hole (11), and the second end (212) of the sliding block (2) covers at least part of the second pen inserting hole (12).

12. The dual-hole sharpener of claim 11, wherein: the double-hole pencil sharpener further comprises an end cover (9) which is arranged on the shell (1) and used for covering the shell (1), wherein the end cover (9) is provided with a first opening (91) communicated with the first pencil inserting hole (11) and a second opening (92) communicated with the second pencil inserting hole (12);

the first cutting assembly (3) comprises a first tool rest (32) communicated with the first pencil inserting hole (11) and a first hob or a first blade (31) arranged on the first tool rest (32), and the motor drives the first tool rest (32) to rotate so as to cut a pencil;

the second cutting assembly (4) comprises a second tool rest (42) communicated with the second pencil inserting hole (12) and a second hob or a second blade (41) arranged on the second tool rest (42), and the motor drives the second tool rest (42) to rotate so as to cut a pencil.

13. The dual-hole sharpener of claim 11, wherein: the aperture of the first pen inserting hole (11) is larger than that of the second pen inserting hole (12).
