The utility model solves the technical scheme that its technical problem used：

A kind of pencil with penknife, it is characterised in that：With upper pen pipe, a pencil with wooden shell is installed in pen Guan Zhong；With a pipe of starting writing, the end for pipe of starting writing is fixed with a penknife, and penknife has solid on flute, penknife If blade the knife edge be located at flute position, penknife also have nib export；Pipe start writing with upper pipe to set respectively After screw thread is spirally connected, the nib of pencil stretches out nib outlet, the wooden shell of the knife edge contact pencil of blade.

Upper pipe upper pen pipe and outside upper pen pipe in coaxial are connected and formed, the gap between interior upper pen pipe and outside upper pipe Formed in annular groove, the internal thread started writing set by pipe and the external thread bolt connection set by interior upper pen pipe, and pipe insertion annular groove of starting writing.

Offer second order hole on the wall of upper pipe, the hole of a second order hole pipe outer wall upward is the screw of major diameter, second order hole The hole of an inside pipe wall is the through hole of minor diameter upward, and the small diameter portion of a second order cylinder passes through after above-mentioned through hole contact in lead On outer wall, the diameter portion of second order cylinder is located in screw, and a bolt is arranged in screw, the two ends point of a spring Other contact bolt and second order cylinder.

With a pen clip, pen clip is arranged on the screw thread set by upper pipe tail end with its screw thread, the clamp contact of pen clip Rubber is plugged with the outer wall of upper pipe, the groove set by pen clip.

It is of the present utility model to be beneficial in that：

The utility model is simple in construction, easy to use, can rotate pipe of starting writing, and pencil is cut, and pipe of starting writing stretches into pen pipe Gap in, nib exposes nib outlet naturally, and the screw thread of start writing pipe and upper pipe is blocked by outside upper pipe, good appearance, The clamping device being made up of bolt, spring, second order cylinder secures pencil, it is to avoid turn start writing pipe when pencil follow rotation.

Embodiment

In order to illustrate more clearly of the technical solution of the utility model, the required accompanying drawing used in description will be made below Simply introduce, it should be apparent that, drawings in the following description are only some embodiments of the present utility model, for this area For those of ordinary skill, on the premise of not paying creative work, other implement can also be obtained according to these accompanying drawings Example.

As shown in Figure 1, Figure 2, shown in Fig. 5, Fig. 6, the utility model has upper pipe 1, and a pencil 4 with wooden shell is inserted simultaneously It is installed in a pipe 1.

With a pipe 2 of starting writing, the end for pipe 2 of starting writing is fixed with a penknife 3, penknife in the way of screw thread is spirally connected 3 have flute 31, and a blade 33 is pressed on flute 31 by a mouth mold insert 32, and with screw 34 a mouth mold insert 32 It is fixed on blade 33 on lower penknife 3, the knife edge of fixed blade 33 is located at the position of flute 31, penknife 3 on penknife 3 Also there is nib outlet 30.

Upper pipe 1 Shang pipe 11 and outside upper pipe 12 in coaxial are connected and formed, interior upper pipe 11 and outside upper pipe 12 Between gap form annular groove 10, the internal thread started writing set by pipe 2 and the external thread bolt connection set by interior upper pipe 11, and start writing In the insertion annular groove 10 of pipe 2.

At this moment the nib of pencil 4 stretches out nib outlet 30, the wooden shell of the knife edge contact pencil 4 of blade 33.

The interior Shang inwall of pipe 11 also has several longitudinal clamping muscle to clamp pencil 4.

Again as shown in Figure 3, Figure 4, three second order holes 5 are offered on the wall of upper pipe 1, second order hole 5 is upward circumference uniform distribution The hole of the outer wall of pipe 1 is the screw 51 of major diameter, and the hole of the inwall of a pipe 1 upward of second order hole 5 is the through hole 52 of minor diameter, one two The small diameter portion 62 of rank cylinder 6 pass through above-mentioned through hole 52 after contact on the outer wall of pencil 4, the major diameter portion of second order cylinder 6 61 are divided to be located in screw 51, a bolt 7 is arranged in screw 51, the two ends difference contact bolt 7 and second order post of a spring 8 Second order cylinder 6 just can be compressed pencil 4 by body 6, bolt 7 using spring 8, and pencil 4 can not be rotated.

With a pen clip 9, pen clip 9 is arranged on the screw thread set by upper tail end of pipe 1 with its screw thread, the clamp of pen clip 9 Rubber 93 is plugged with the outer wall of 91 contact on pipes, the groove 92 set by pen clip 9.

When the pen core of pencil 4 is write soon not to be had, pipe 2 of starting writing can be rotated, such blade 33 can prune the wooden of pencil 4, The spiral shell of pipe 2 of starting writing simultaneously enters the screw thread of interior upper pipe 11, the nib of pencil 4 is exposed nib outlet 30, in the process due to two Rank cylinder 6 compresses pencil 4, and pencil 4 can not be rotated, and penknife 3 just can be with normal work.

The embodiment of each in this specification is described by the way of progressive, and what each embodiment was stressed is and other Between the difference of embodiment, each embodiment identical similar portion mutually referring to.To the upper of the disclosed embodiments State bright, professional and technical personnel in the field is realized or use the utility model.A variety of modifications pair to these embodiments It will be apparent for those skilled in the art, generic principles defined herein can not depart from this reality In the case of with new spirit or scope, realize in other embodiments.Therefore, the utility model is not intended to be limited to this These embodiments shown in text, and it is to fit to the most wide scope consistent with features of novelty with principles disclosed herein.
