Detailed Description

The present invention will be further described with reference to the accompanying fig. 1-4 and the detailed description.

In the description of the present invention, it should be noted that the terms "upper", "lower", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.

A pencil sharpener holder comprises a holder body 1, wherein a blade mounting surface 11 for placing a blade is obliquely arranged on the holder body 1, a single-hole blade 3 or a double-hole blade 2 can be mounted on the holder body, and a third mounting hole 113 for mounting the single-hole blade 3 and a first mounting hole 111 and a second mounting hole 112 for mounting the double-hole blade 2 are formed in the blade mounting surface 11.

In order to make the structure of the tool holder small and simple, the third mounting hole 113 is disposed between the first mounting hole 111 and the second mounting hole 112, and the first mounting hole 111, the second mounting hole 112, and the third mounting hole 113 are linearly distributed along the length direction of the insert mounting surface 11, so that the size of the insert mounting surface 11 is reduced, thereby reducing the manufacturing cost of the tool holder.

Further, the holder body 1 is provided with a wood cutting area 13 and a lead cutting area 12 for cutting the pencil, and the wood cutting area 13 and the lead cutting area 12 are distributed along the insertion direction of the pencil, so that when the double-hole blade 2 is mounted, the blade edge of the double-hole blade in the cutting area is further prevented from being deformed, the first mounting hole 111 is close to the lead cutting area 12, and the second mounting hole 112 is close to the wood cutting area 13.

Further, the third mounting hole 113 is formed in the middle of the blade mounting surface 11, and when the single-hole blade 3 is mounted, the third mounting hole 113 in the middle is more favorable for force dispersion, so that the stability of mounting the single-hole blade 3 is improved.

In order to further prolong the service life of the blade, the back side of the blade mounting surface 11 is provided with a hole column 114 corresponding to the mounting hole, the depth of the mounting hole is lengthened, the effective locking depth of the screw is lengthened, the locking force of the screw is increased, the extrusion force of the blade to the blade mounting surface 11 is larger, and the blade is less prone to warping or being damaged when a pencil extrudes the blade outwards.

When the pencil is cut, the pencil can produce tangential force to the blade, makes the blade have the trend of removing to the cutting area of keeping away from the knife rest, in order to prevent that the blade from removing it establishes a plurality of lugs 115 to keep away from one side of cutting area on the blade installation face 11, and lug 115 has limit function, can withstand the blade, and in preferred embodiment, the quantity of lug 115 is two, and two lugs 115 are established the length direction's of blade installation face both ends, and two lugs 115 can withstand the both ends of the back of the knife edge side of blade simultaneously, have increased the atress strong point, are favorable to restricting the blade removal more.

When the pencil is cut daily, the single-hole blade 3 is selected, the self-tapping screw is locked into the third mounting hole 113, the single-hole blade 3 is fixed on the blade mounting surface 11, the pencil is inserted into the cutting area of the tool rest body 1, and the tool rest body 1 is rotated to finish pencil cutting; when the pencil is cut for a long time, the double-hole blade 2 is selected, the self-tapping screws are locked into the first mounting hole 111 and the second mounting hole 112, the double-hole blade 2 is fixed on the blade mounting surface 11, the pencil is inserted into the cutting area of the tool rest body 1, and the tool rest body 1 is rotated to finish pencil cutting.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and 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 skilled in the art that various changes in the embodiments and modifications thereof may be made, and equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
