Abstract

The utility model discloses a pencil clamp of a pencil sharpener, aiming to provide a pencil clamp which can realize the automatic driving and reversing of a penholder through the rotation of a veneering knife without the role of a guide pole and can be operated conveniently. The utility model comprises a holding frame with a cirque in the middle, a rotary disc with a hollow convex ring in the middle, a rotor axis, a gear and a rubber wheel. One side of the holding frame near the rotary disc is provided with four longitudinal supporting axles, the rotary disc is arranged between the holding frame and the rubber wheel, the outside of hollow convex ring of the rotary disc nests with the cirque of the holding frame, the inside of hollow convex ring of the rotary disc nests with the penholder guide hole of the veneering device and four salient points are arranged on the rim of one of the faces of the rotary disc facing a clamp wheel.

Description

The pen clip of penknife

Technical field:

The utility model belongs to stationery, relates in particular to a kind of pen clip mechanism arrangement of penknife.

Background technology:

The pen clip of existing penknife generally is made up of pen clip rotating disk and three block teeth, during operation, pulling lever that the pen clip rotating disk exposes makes the pen clip rotating disk drive three inner block teeth to open, insert then pencil to support revolve the cutter place, shed external force, three block teeth clamp pen and do under the effect of back-moving spring, revolving cutter cuts, along with the rotation of revolving cutter, pen is done under the effect of two guide rods that have a spring, goes forward one by one till cutting gradually.Finish and to pull lever once more after the cutting block teeth are opened, take out the pencil of cutting.The parts of its device are various, and operation comparatively bothers.

Summary of the invention:

The purpose of this utility model is that design is a kind of easy and simple to handle, does not need the effect of guide rod, by revolving the rotation of cutter, just can realize the pen clip of penknife of the automatic advance and retreat of penholder.

The purpose of this utility model is achieved through the following technical solutions.

Took turns with rotating disk, rotating shaft, gear and the rubber of hollow bulge loop the bracing frame of band annulus, centre in the middle of the utility model comprised, described bracing frame has four back shafts longitudinally by the one side of rotating disk, described rotating disk is between bracing frame and rubber wheel, and the hollow bulge loop outside of rotating disk is nested with the annulus of bracing frame, the inboard is nested with the penholder pilot hole that revolves knife system, and rotating disk has four small salient points on the edge of the one side of clip wheel.

Be provided with the waisting of a pen clip in the middle of the described rubber wheel; On the two extending transversely bars of the described bracing frame back side locating hole is arranged respectively; The groove of placing rotating shaft is arranged respectively on the described back shaft, and in a pair of back shaft, one of them becomes transverse opening, and another is a longitudinal opening; The hollow prominent ring outside in the described rotating disk is an annulus, and the inboard is eight side rings; Described gear, rotating shaft and rubber wheel are connected and are fixed together.

Characteristics of the present utility model are: pen clip directly links to each other with the penholder pilot hole that revolves knife system, and elasticity of demand guide rod not just can be realized the automatic advance and retreat of penholder by the rotation of revolving cutter.It is simple in structure, and cost is lower, and is easy to operate.

The specific embodiment:

The utility model will be further described below in conjunction with accompanying drawing:

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, the utility model mainly is made up of with rotating disk 2, rotating shaft 3, gear 4 and the rubber wheel 5 of hollow prominent ring bracing frame 1, the centre of centre band annulus.Except that other parts of rubber wheel 5 pen clips are made by plastics.On the two extending transversely bars of bracing frame 1 back side locating hole 6 is arranged respectively, pen clip is fixed on the penknife by locating hole 6.Bracing frame 1 has four back shafts 8 longitudinally by the one side of rotating disk, a groove 10 of placing rotating shaft is arranged respectively on each back shaft 8, in a pair of back shaft 8, have one to become transverse opening, another is a longitudinal opening, and this design can make being placed on the back shaft 8 that rotating shaft 3 is stabilized.Being provided with the waisting of a pen clip in the middle of the rubber wheel, is the position of inserting penholder.Rotating disk 2 is between bracing frame 1 and rubber wheel 5, hollow bulge loop 9 outsides in the rotating disk 2 are that the annulus 11 of annulus and bracing frame 1 is nested, hollow bulge loop 9 inboards are eight side rings, are the positions that is nested with the penholder pilot hole that revolves knife system (Fig. 5), are driven the rotation of rotating disk 2 by the rotation of revolving cutter.Rotating disk 2 has four small salient points 7 on the edge of the one side of rubber wheel 5.When rotating disk 2 rotates, produce friction between four small salient points 7 on the rotating disk 2 and the gear 4, the rotation of driven gear 4, gear 4, rubber wheel 5 are connected with rotating shaft 3 and are fixed together, when gear 4 rotates and then drive rotating shaft 3 and rubber is taken turns 5 rotations together.

The back side with the pencil inlet is sightingpiston, when revolving cutter (Fig. 5) when turning clockwise, driving rotating disk 2 by the penholder pilot hole clockwise rotates, small salient point 7 slip gears 4 during rotation on the rotating disk 2, make gear 4 toward the opposed inside rotation, rotating shaft 3 this moment and rubber wheel 5 turn to the inside simultaneously, and the rotation of rubber wheel 5 drives the pencil that is pressed from both sides and moves near the direction of revolving cutter toward the penholder pilot hole, cuts thereby make pencil revolve cutter along with the rotation of revolving cutter is sent to.Cutting finishes, and is rotated counterclockwise to revolve cutter, and rotating disk 2 is rotated counterclockwise simultaneously, friction by small salient point 7, gear 4, rotating

shaft

3 and 5 on rubber wheel laterally rotate simultaneously, and the pencil that 5 drives of rubber wheel are pressed from both sides is past to be moved away from the direction of revolving cutter, thereby finishes the step that pencil withdraws from.
