For example,
preferably, the centering device 100 further comprises, for example: a center positioning device housing 150. The center positioning device housing fixes the first slider 110, the second slider 120, and the transmission portion 130 to the center positioning device housing 150.
Further, the first slider 110 and the second slider 120 are disposed between the transmission portion 130 and the center positioning device housing 150, at this time, the transmission portion 130 fixes the first slider 110 and the second slider 120 on the center positioning device housing 150, or the transmission portion 130 is disposed between the first slider, the second slider 120 and the center positioning device housing 150, at this time, the first slider and the second slider 120 fix the transmission portion 130 on the center positioning device housing 150, and here, the positional relationship among the first slider 110, the second slider 120, the transmission portion 130 and the center positioning device housing 150 is not limited.

Preferably, the upper end opening of the input end 111 is larger than the lower end opening. The input end 111 is arranged in a large-end and small-end mode, and the pencil can be conveniently inserted from the input end 111.
[ second embodiment ]
Referring to fig. 5, a schematic structural diagram of a triggering device 200 according to an embodiment of the present invention is shown, for example, including: the center positioning device 100 and the trigger according to the first embodiment. The trigger is provided with a switch (not shown in the figures), and the trigger and the transmission part 130 cooperate to control the switch, where the switch may be a point-shaped contact switch or a point-shaped contact switch with a spring piece, and the type of the switch is not limited herein.
Further, referring to fig. 6, the triggering device 200 further includes, for example: a conductor (not identified in the figures); the conductive member, for example, includes: control member 210 includes a first conduction site 221 and a third conduction site 223. Wherein the first conducting site 221 is disposed between the third conducting site 223 and the transmission input end 135. For example, the initial position is that the control member 210 is located at the third conducting position 223 as shown in fig. 7, and the switch is in the on state; when the first slider 110 and the second slider 120 move to both sides, the control transmission part 130 moves backward, and when the control member 210 moves from the third transmission position 223 to the first transmission position 221 and is in the state shown in fig. 8, the position of the control member 210 is lowered relative to the position in the initial state, and the bottom end of the control member 210 contacts the switch, so that the switch is in the closed state.
Preferably, the conductor further includes, for example: a second conducting bit 222; the second conductive site 222 is disposed between the first conductive site 221 and the third conductive site 223. Wherein, when the control member 210 enters the second conduction position 222 from the third conduction position 223, the switch is in an open state; when the control member 210 enters the first conduction position 221 from the second conduction position 222, the switch is in a closed state.
Further, the first conducting site 221 is a plane vertically disposed on the control member 210; the third conducting site 223 is a plane parallel to the first conducting site 221, and the third conducting site 223 is higher than the first conducting site 221; the second conducting site 222 is a ramp connected between the first conducting site 221 and the third conducting site 223.
For example, when the control member 210 is located on the third conduction position 223, the control member 210 and the switch are in the initial state with a certain gap in the vertical direction; when the input end 111 controls the transmission part 130 to move backwards, since the third transmission position 223 is a plane, when the control member 210 is on the third transmission position 223, the distance between the control member 210 and the switch is in a fixed state. When the control member 210 enters the second conduction position 222 from the third conduction position 223, since the second conduction position 222 is an inclined surface, when the transmission part 130 moves backward, the control member 210 slides downward along the inclined surface of the second conduction position 222. When the control member 210 enters the first conduction position 221 from the second conduction position 222, the control member 210 just triggers the switch; since the first transmission position 221 is a plane, the transmission portion 130 does not drive the control member 210 to move downward when moving backward, so as to prevent the control member 210 from pressing the switch, thereby damaging the switch.
Preferably, in conjunction with fig. 9 and 10, the triggering device 200 further includes, for example: a trigger device upper shell 241, a trigger device lower shell 242 and at least one second elastic member 243; the second elastic elements 242 are disposed between the upper triggering device case 241 and the lower triggering device case 242. When the control member 210 is located at the third conduction position 223, the second elastic member 243 is in a natural state; when the control member 210 is located at the first transmission position 221, the second elastic member 243 is in a compressed state; when the control member 210 needs to be returned, the second elastic member 243 drives the upper casing 241 of the triggering device to rise upward, so that the switch is turned off.
[ third embodiment ]
Referring to fig. 11 and 12, an electric sharpener 300 according to a third embodiment of the present invention is provided, where the electric sharpener 300 includes: an upper end cap 310, a pen feeding mechanism, a cutting mechanism 320, and a power mechanism 330. The pen feeding mechanism is arranged below the upper end cover 310; the cutting mechanism 320 is arranged below the pen feeding mechanism; the power mechanism 330 is connected below the cutting mechanism 320.
Preferably, referring to fig. 13, the upper end cap 310 of the electric pencil sharpener is further provided with a plurality of grooves 311, the transmission part 130 is provided with protrusions oppositely, and the plurality of grooves 311 of the upper end cap 310 of the electric pencil sharpener are matched with the protrusions of the corresponding transmission part 130, so that the transmission part 130 can move only in one direction, and the triggering stability of the electric pencil sharpener 300 is improved.
Specifically, the upper end cap 310 is further provided with a pen inlet 312, and the pen inlet 312 is disposed corresponding to the input end 111. For example, when the pencil enters the input end 111 from the pencil inlet 312, the pencil presses the first slider 110 and the second slider 120 to move outward, the first slider 110 and the second slider 120 move, and simultaneously, the first matching piece 133 and the second matching piece 132 drive the transmission portion 130 to move to one side of the control member 210, and simultaneously, the control member 210 enters the second transmission position 222 from the third transmission position 223 and then enters the first transmission position 221 from the second transmission position 222; when the control member 210 enters the first conducting position 221, the control member 210 touches the switch to operate the electric pencil sharpener 300.
Preferably, when pencils with different thicknesses are cut by the electric sharpener 300, the control member 210 does not descend after being located at the first conducting position 221, i.e., does not move downward after triggering the switch, so pencils with different thicknesses can also be applied to the electric sharpener 300.
Specifically, referring to fig. 14, the electric sharpener 300 further includes, for example: control mounting locations 313. The control member mounting location 313 defines a moving direction of the control member 210. For example, when the transmission portion 130 controls the control member 210 to move downward, the control member mounting portion 313 defines the control member 210, so that the control member 210 can only move in the vertical direction, and the control member 210 can precisely trigger the switch, thereby controlling the opening of the electric sharpener 300.
Preferably, the switch is arranged in the pen feeding mechanism, and the power mechanism 330 is provided with a stop trigger switch. The upper end cap 310 is fixedly connected with the pencil feeding mechanism, and the pencil feeding mechanism 320 is slidably connected with the cutting mechanism 320, so that the upper end cap 310 and the pencil feeding mechanism can be detached simultaneously and separated from the cutting mechanism 320, and the cutting mechanism 320 cannot pollute the switch in the pencil feeding mechanism when dumping pencil chips. In addition, the cutting mechanism 320 and the power mechanism 330 are fixedly connected, and the cutting mechanism 320 and the power mechanism 330 do not need to be separated before the pencil scraps are poured, so that the problem that the cutting mechanism 320 and the stop trigger switch cannot be aligned when the cutting mechanism 320 and the power mechanism 330 are installed again is solved.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
