Technical Field

The invention relates to a pencil sharpener, in particular to a pencil sharpener capable of prompting sharpening.

Background

Generally, after a pencil is used for a period of time, a pen point of the pencil becomes blunt and short, and the pen point needs to be shaved by a sharpener so that a refill inside the pencil is exposed and sharpened, thereby facilitating subsequent writing or drawing by a user.

Referring to fig. 12 and 13, a pencil sharpener 80 with a sharpening prompting device includes a housing 81, a prompting button 82 and a pushing block 83, the housing 81 has a receiving groove 811, a locking protrusion 812 and a pencil sharpener 813, wherein the receiving groove 811 is formed by the surface of the housing 81 being recessed; the locking protrusion 812 is protruded on the inner sidewall of the receiving groove 811; the pencil sharpener 813 is disposed inside the housing 81 and spaced apart from the accommodating groove 811 for inserting a pencil 90 and sharpening the pencil 813 by a blade 814.

The push block 83 is slidably disposed in the bottom of the pencil sharpener 813 and can be slidably abutted against the snap arm 822, in operation, a user firstly presses the push button 82 to position the snap arm 822 at a snap position as shown in fig. 13, when the pencil 90 is sharpened to a predetermined sharpness, the pen point 91 pushes the push block 83 to slide the push block 83 and abut against the snap arm 822, and after the snap arm 822 is pushed, the snap portion 823 is disengaged from the snap bump 812, so that the restoring force of the compression spring 821 enables the push button 82 to be disengaged from the snap position to be ejected, thereby prompting the user that the pencil 90 has been sharpened.

However, the conventional pencil sharpener 80 has the following disadvantages:

1. as shown in fig. 14, the direction of the locking portion 823 and the locking protrusion 812 is the same as the direction of the swing of the locking arm 822, so that in the process of the swing of the locking arm 822 to make the indication button 82 get out of the locking position and pop out, the locking portion 823 must directly pass over the locking protrusion 812, and the contact area between the locking portion 823 and the locking protrusion 812 is smaller as the locking arm 822 swings outwards, as shown in fig. 14, the sharp end of the locking portion 823 at the end is left to abut against the locking protrusion 812, and therefore, after long-term use, the locking portion 823 is easily worn or even broken.

2. As shown in fig. 15, after the fastening portion 823 is worn, the area of the abutting surface of the fastening protrusion 812 and the fastening portion becomes smaller, in other words, the fastening force of the fastening arm 822 and the fastening protrusion 812 is weakened, so that the indication button 82 is more and more easily separated from the fastening position to be ejected, and even if the pencil 90 is not sharpened, the indication button 82 may be ejected by shaking during the sharpening process, so that the existing pencil sharpener is disabled after being used for a period of time, and the sharpening indication function cannot be provided.

In detail, as shown in fig. 7 and 10, one end of the at least one triggering member (e.g., the triggering member 32 or the triggering member 32A) pivotally connected to the corresponding tool holder (e.g., the tool holder 33 or the tool holder 33A) is provided with a sleeving part (e.g., the sleeving part 321 or the sleeving part 321A), the sleeving part 321 is sleeved on the pivot 352 of the tool holder 33, the sleeving part 321A is sleeved on the pivot 352A of the tool holder 33A (e.g., the tool holder 33, the body 35A of the tool holder 33A is provided with a pivot 352A) to form the pivotal connection structure, the sleeving part 321 and the sleeving part 321A are provided with the yielding space 320 of the pivotal connection structure, and the cross-sectional area of the yielding space 320 is larger than the cross-sectional areas of the pivot 352 and the pivot 352A, so that the at least one triggering member (e.g., the triggering member 32 and the triggering member 32A) can move relative to the; in the preferred embodiment of the present invention, the triggering member 32 and the triggering member 32A are both swing type triggering members, so that the triggering member 32 and the triggering member 32A move relative to the tool seat 33 and the tool seat 33A respectively in the above manner.

As shown in fig. 7 to 10, when the user sharpens the pencil 90 through one of the pencil sharpeners 30, one end of the pencil 90 extending into the tapered slot 31 pushes the trigger 32 to swing, and further pushes the elastic arm 221 to deform and swing, so as to disengage from the two snap arms 212, at this time, the deformed elastic arm 221 abuts, the trigger 32A of the other pencil sharpener 30A moves in the receding space 320 relative to the pivot 352A pivoted thereto, so that the elastic arm 221 can smoothly disengage from the two snap arms 212, and the actuating unit 201 of the prompting assembly 20 pushes the prompting button 22 to the outside of the mounting portion 21, so as to prompt the user that the pencil 90 has been sharpened, as shown in fig. 9, due to the elastic restoring force of the elastic arm 221, when the pencil 90 is drawn out, the elastic arm 221 returns to a position parallel to the two snap arms 212, since the position of the indication button 22 after being ejected needs to be pressed by the user when the user operates the indication button 22 next time, the elastic arm 221 will be buckled with the two buckling arms 212 again, and the swinging trigger 32 will be pressed against the tapered groove 31 in the opposite direction and reset due to the reset motion of the elastic arm 221, so as to facilitate the user to use again, and the user operates the other pen sharpening base 30A in the same motion manner, thereby having the same convenience.

Preferably, as mentioned above, since the X direction and the Y direction form a non-parallel included angle relationship, the present invention not only can solve the problem that the clipping portion of the existing cue button is easily worn to cause the sharpening cue function to fail, but also can arrange two pencil sharpening bases (i.e. the pencil sharpening base 30 and the pencil sharpening base 30A) at two sides of the elastic arm 221, thereby achieving the effects of bidirectional pencil sharpening and sharing the same cue button 22; moreover, in the preferred embodiment of the present invention, the included angle between the X direction and the Y direction is 90 degrees, that is, the swinging direction of the elastic arm 221 is perpendicular to the buckling direction of the elastic arm 221 and the two buckling arms 212, so that friction between the elastic arm 221 and the buckling arms 212 during tripping can be reduced compared to the case of non-90 degree included angle or parallel, and when one triggering member (e.g., the triggering member 32 or the triggering member 32A) pushes the elastic arm 221, the elastic arm 221 can vertically push the other triggering member (e.g., the triggering member 32A or the triggering member 32A) opposite to the other triggering member, thereby avoiding resistance generated by the opposite triggering member.

As shown in fig. 10, in the preferred embodiment of the present invention, the engaging portion 321 is a claw portion, so that the yielding space 320 forms an elongated hole extending longitudinally along the swing direction (Y direction) of the elastic arm 221, and the length L is in the longitudinal direction, within the range of the length L, the engaging portion 321 can move relative to the pivot 352, and the length L is the distance that the trigger 32 can move relative to the tool holder 33 along the swing direction (Y direction) of the elastic arm 221.

Further, as shown in fig. 8, 11 and 11A, in order to enable the user to easily disengage the elastic arm 221 to prompt sharpening, a distance between positions where the trigger 32, the trigger 32A and the elastic arm 221 abut against each other is smaller than a distance between the latching protrusions 213 of the two latching arms 212 and the fulcrum F, so that the distance L1 required by the trigger 32 or the trigger 32A to push the elastic arm 221 to disengage along the swing direction (Y direction) is smaller than a distance L2 required by the elastic arm 221 to disengage from the latching protrusions 213 along the swing direction (Y direction) (i.e., L1 is smaller than L2), for example, the thickness of the elastic arm 221 is 0.8 length units, when the elastic arm 221 moves 0.8 length units relative to the latching protrusions 213 along the Y direction, the elastic arm 221 can disengage (i.e., L2 is 0.8), since the distance between the position where the trigger 32 or the trigger 32A abuts against the elastic arm 221 and the fulcrum F is smaller than the distance between the position where the elastic arm 221 is engaged with the engaging protrusion 213 of the engaging arm 212 and the fulcrum F, one of the trigger 32 or the trigger 32A moves 0.4 length unit along the Y direction (i.e., L1 is 0.4), so that the elastic arm 221 can move 0.8 length unit to complete the disengaging operation, thereby achieving the effect of prompting sharpening without requiring a great deal of operation.

As shown in fig. 7, 8, 10 and 11, in the embodiment of the present invention with two pen sharpeners, in order to avoid that when any trigger (e.g. the trigger 32 or the trigger 32A) swings, the elastic arm 221 is abutted by the other trigger (e.g. the trigger 32A or the trigger 32A) and cannot swing to release, the length L of the clearance space 320 should be greater than or equal to the moving amount L1 (i.e. L ≧ L1) of the trigger along the swinging direction, which is enough to push the elastic arm 221 to release (disengage from the at least one latch arm 212), so that when a user uses only one of the pen sharpeners (e.g. the pen sharpeners 30 or the pen sharpeners 30A) at the same time, the elastic arm 221 can be surely pushed and can disengage from the latch position, so that the prompt button 22 pops up to prompt sharpening.

In addition, each triggering member (e.g., the triggering member 32A) can be pivoted to the tool seat (e.g., the tool seat 33A) by other methods, for example, the pivoting end of the triggering member 32, the triggering member 32A forms a closed hole, and the corresponding tool seat 33, the tool seat 33A respectively form a latch at two sides of the closed hole, so that the triggering member 32, the triggering member 32A are pivoted to the tool seat 33, the tool seat 33A by the two latches to rotate relative to the tool seat 33, the tool seat 33A.

By the above technical features, the invention has the advantages that the buckling direction of the elastic arm 221 and the at least one buckling arm 212 and the swinging and releasing direction of the elastic arm 221 are non-parallel with an angle, with independence of movement, the positioning shoulder 222 can be configured to bear against the at least one snap arm 212 over a large area, the resilient arm 221, during disengagement from the at least one latch arm 212, does not directly abut the at least one latch arm 212 with the tip of the positioning shoulder 222 to laterally pass over the at least one latch arm 212 to cause tip damage, even though the surface of each positioning shoulder 222 may rub during disengagement, because the positioning shoulders 222 bear against a large area, the friction also does not reduce the effective contact area required for the surface of the positioning shoulder 222 to engage the at least one snap arm 212, so that the elastic arm 221 cannot be effectively fastened to the at least one fastening arm 212 after a period of use; in summary, the invention solves the problem that the sharpening prompting function is invalid due to the fact that the buckling part 823 of the prompting button 82 is easily worn after the existing pencil sharpener is used for a long time, and further provides the pencil sharpener capable of prompting sharpening and being durable in use.
