FIG. 1 is a schematic diagram of a pen point delay protection structure of a pencil sharpener.

Fig. 2 is an enlarged schematic view of a in fig. 1.

Fig. 3 is a partial structural schematic diagram of fig. 1.

In the figure, the device comprises a transmission rod 1, a transmission rod 2, a primary gear 3, a secondary gear 4, a transmission gear 5, a return spring 6, a sliding plate 7, a touch switch 8, a shell 9, an electric cutting head 10, a pen point inserting hole 11, a driving gear 41, a circular truncated cone 61, a positioning hole 62 and a spring positioning block.

Detailed Description

Referring to fig. 1 to 3, the pencil point delay protection structure of the pencil sharpener comprises a transmission rod 1, a first-stage gear 2, a second-stage gear 3 and a transmission gear 4, wherein the first-stage gear 2 is meshed with the second-stage gear 3, the second-stage gear 3 is meshed with the transmission gear 4, a driving gear 11 is arranged at the bottom of the transmission rod 1, when the transmission rod 1 moves downwards, the driving gear 11 is meshed with the first-stage gear 2, and when the transmission rod 1 moves upwards, the driving gear 11 is separated from the first-stage gear 2.

The top of the transmission rod 1 is inserted into the electric cutting head 9, and the transmission rod 1 is positioned right below the pen point insertion opening 10.

Two round platforms 41 are arranged on the end surface of the transmission gear 4.

The pencil point time-delay protection structure of the pencil sharpener further comprises a spring 5, a sliding plate 6, a touch switch 7 and a shell 8, wherein the sliding plate 6 is provided with two positioning holes 61, and the positioning holes 61 are waist-shaped holes. The two circular tables 41 are respectively positioned in the two positioning holes 61, and the circular tables 41 can move in the positioning holes 61. The end of the sliding plate 6 is provided with a spring positioning block 62, and two ends of the spring 5 respectively abut against the spring positioning block 62 and the shell 8. The trigger switch 7 can be controlled by sliding the sliding plate 6, and the trigger switch 7 can stop the operation of the electric cutting head.

The working principle of the utility model is as follows: when the pencil is cut to the tail end of the pencil belt, the pencil point presses down the top of the transmission rod to drive the transmission rod to move downwards, so that the driving gear is meshed with the primary gear, and the secondary gear and the transmission gear drive the sliding plate to slide to control the touch switch to stop the electric cutting head from running, thereby achieving the effect of delaying time.
