In the prior art automatic advance and retreat pen sharpener, the pencil sharpener is in the process of pencil sharpening, the two sides of the movable bracket and the fixed bracket are clamped and fixed, and the corresponding unlocking block and pen point are arranged in the fixed bracket. Stopper, after the pencil is sharpened, the nib stopper drives the unlocking block to unlock, the movable bracket is separated from the fixed bracket, and the pencil is automatically returned after unlocking, but the structure in the prior art often has a unilateral unlocking situation. One side is unlocked, and the other side of the one-sided unlocking movable bracket is still stuck with the fixed bracket. At this time, the pencil cannot be automatically returned, and the pencil sharpener will not be able to sharpen or return the pen.

Embodiment Construction
[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0023] combined with Figure 1-2 As shown, the invention discloses a linkage mechanism of the unlocking block of a pencil sharpener, image 3 and Figure 4 Shown is a schematic structural diagram of the movement of the automatic advance and retreat pen sharpener, image 3 and Figure 4 It is a structural schematic diagram of removing the external casing and the sawdust box.
[0024] Such as figure 1 and figure 2 As shown, a pencil sharpener linkage unlocking device includes a nib block 1 and an unlocking block 2 respectively located on both sides of the nib block 1, and a linkage device that drives each other is provided between the two unlocking blocks 2, and any unlocking block 2 unlocking can drive another unlocking block 2 to unlock through the linkage device.
[0025] The linkage device is a ring gear 3 cooperating with two unlocking blocks 2 , a...

The invention discloses a linkage unlocking device of a pencil sharpener, a pencil sharpener core and the pencil sharpener. The linkage unlocking device comprises a pencil point stop block (1) and unlocking blocks (2) located on the two sides of the pencil point stop block (1) correspondingly. The linkage unlocking device is characterized in that a linkage device for driving the two unlocking blocks (2) is arranged between the two unlocking blocks (2), and when any unlocking block (2) is unlocked, the other unlocking block (2) can be driven to be unlocked through the linkage device. Compared with the prior art, the linkage unlocking device has the beneficial effects that through the arrangement of the linkage device, the unlocking blocks on the two sides are unlocked at the same time, and the situation that due to single-side unlocking, a pencil cannot be sharpened, idles and cannot retreat is avoided. The linkage unlocking device of the pencil sharpener, the pencil sharpener core and the pencil sharpener are simple in structure, the two unlocking blocks can be unlocked at the same time, and the situation that the pencil cannot be sharpened and cannot retreat is eradicated.
Description
technical field [0001] The invention relates to the technical field of pencil sharpeners, in particular to a linkage unlocking device for an automatic advance and retreat pen sharpener, a pencil sharpener core and a pencil sharpener. Background technique [0002] Pencil sharpeners are commonly used stationery for sharpening pencils. The structures of pencil sharpeners in the prior art are various, and most of them are hand-operated for cutting. Hand-operated pencil sharpeners are divided into automatic advance and retreat pen type and semi-automatic pen advance After the pencil is plugged in, the pencil can be advanced and retracted automatically by shaking the handle. This structure has more advantages than the semi-automatic pen-feeding type. The semi-automatic pen-feeding type sharpens the pencil. After the pencil is finished, the pencil needs to be pulled out. It is easy to break the pencil tip during the pulling process. The automatic advance and retreat pen type pencil...
