Abstract

The utility model discloses a pencil clamping mechanism for a pencil sharpener. The utility model comprises a claw seal plate, claw swing arms and jaw clamps, wherein, the claw seal plate is provided with shafts for the jaw clamps, and the claw swing arms are sheathed on the shafts for the jaw clamps; at the same time, the tail part of each of the jaw clamps sheathed on the shafts for the jaw clamps is provided with an elbow, the middle part of the tail part is provided with a strip-shaped hole, and each of the shafts for the jaw clamps is penetrated through the strip-shaped hole. The jaw clamps of the pencil clamping mechanism for a pencil sharpener can clamp a pencil in optimal positions, the pencil can be stably clamped, and the external surface of the pencil is not easily damaged. Therefore, the pencil clamping mechanism can raise the cutting effect of a pencil sharpener and decrease lead breakage rate.

Description

The pencil holding mechanism of penknife

The utility model relates to the pen clip device on a kind of stationery, particularly penknife.

At present, increasing people adopts penknife cutting pencil.Penknife has characteristics such as health easy to use, safe, core-breaking rate be low, is well received by consumers.In penknife, its pencil holding mechanism generally is made up of three pawl folders in envelope claw-plate, pawl swing arm, spring and the pawl swing arm.When reality is used, it is found that present pencil holding mechanism can't very stably clamp pencil, pencil can produce slight rocking in being cut process, directly influence the cutting effect of pencil.Simultaneously, owing to have only three pawl folders, need to tend to damage the outer surface of pencil with stronger clamping force.

The purpose of this utility model is to overcome the problems referred to above, and a kind of structure improved penknife pencil holding mechanism is provided.

The purpose of this utility model realizes by following technical proposal: this pencil holding mechanism comprises envelope claw-plate, pawl swing arm and pawl folder, and the pawl folder axle of several circular distribution is arranged on the envelope claw-plate, and the pawl swing arm is socketed on the pawl folder axle, and the pawl swing arm can be rotated around pawl folder axle.The edge of pawl swing arm is provided with handle, between pawl swing arm and the envelope claw-plate back-moving spring is set.The pawl chuck is connected on the pawl folder axle, and pawl folder afterbody has an elbow, and this elbow is embedded in the pawl swing arm.The middle part of pawl folder is provided with bar hole, and pawl folder axle runs through bar hole.Therefore, the pawl swing arm is rotated and can be driven each pawl folder rotation together.When being in initial position under the effect of pawl swing arm at back-moving spring, the head of each pawl folder condenses together; When making pawl swing arm rotating certain angle, each pawl folder meeting is rotated and a translation around pawl folder axle, and the head of each pawl folder is to diffusion all around; At last, insert pencil and decontrol the pawl swing arm, pawl swing arm meeting is replied to initial position under the effect of back-moving spring, makes the head polymerization of each pawl folder, and pencil is clamped.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is elaborated.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is an envelope claw-plate front view of the present utility model.

Fig. 3 is a pawl swing arm front view of the present utility model.

Fig. 4 is a pawl folder front view of the present utility model.

Fig. 5 is a pawl folder side view of the present utility model.

As shown in Figure 1, the pencil holding mechanism of this penknife mainly is made up of envelope claw-plate 1, pawl swing arm 2, pawl folder 3 and spring 4.Four to six equally distributed pawl folder axles 11 are arranged on the envelope claw-plate 1.As shown in Figure 2, be provided with six pawl folder axles 11 in the present embodiment, on each pawl folder axle 11 pawl folder 3 arranged all.The shape of pawl swing arm 2 as shown in Figure 3, its center is circular, and can just be enclosed within on the pawl folder axle 11.The outer of pawl swing arm 2 is provided with handle 21, and pawl swing arm 2 is provided with six equally distributed circular holes 22.The shape of pawl folder 3 as shown in Figure 4 and Figure 5, pawl folder 3 in the form of sheets, its head has teeth 33, the middle part is a bar hole 31, afterbody is provided with elbow 32.During installation, pawl folder 3 is enclosed within on the pawl folder axle 11 by bar hole 31, and the afterbody of pawl folder 3 is embedded in the circular hole 22 of rolling disc 2.

Compared with prior art, the utility model is put at pawl because bar hole is adopted at the middle part of pawl folder In the arm rotation process, the pawl folder also has translation except rotating, so that pawl folder change in location is remarkable, and energy Clamp pencil with the optimum position; Simultaneously, the quantity of pawl folder increases to four to six, and not only pen clip is more steady Fixed, and the outer surface of easy damaged pencil not. In a word, the utility model can improve the penknife structure Cutting effect, reduce core-breaking rate.
