Description
Technical field
The present invention relates to cultural goods technical field, especially a kind of penholder of use pencil-lead.
Background technology
At present, it is divided into two kinds of push type and driving using the pencil of pencil-lead, pencil-lead is placed on by push type pencil
In penholder, pencil-lead is pressed by the briquetting for being located at penholder afterbody, a pencil-lead is often pressed and stretches out one section, this pencil book
Slightly exerted oneself when writing, pencil can be retracted penholder, there is also the phenomenon that pen core fractures；Propelling pencil be pencil-lead is made it is small
Section, then the pencil-lead of some segments is put into plastic tube, after writing a period of time, when pencil-lead above is left a bit, push away
The dynamic pushing block for being located at penholder afterbody ejects new pen core old pen core, and propelling pencil, which has pen core segment section, to be write,
Wasting problem.
The content of the invention
It is an object of the invention to provide a kind of cutting-free pencil penholder, it can solve current cutting-free pencil penholder can not
All of, cause to waste and the problem of pencil-lead frangibility.
In order to solve the above problems, the technical solution adopted by the present invention is：The upper body of rod including one end flexible connection is with
Spill spin block is connected through a screw thread at the top of the body of rod, the upper body of rod, the bottom of the spill spin block is connected with depression bar；The lower beam
The bottom of body is provided with a mouth, and described mouth stretches out hole provided with pencil-lead, and the pencil-lead, which stretches out, is provided with pencil-lead positioning sleeve in hole；
It is provided between the depression bar and described mouth outside pencil-lead, the pencil-lead and is cased with telescopic protective cover.
In above technical scheme, further scheme can be：The upper body of rod is pipe body, and its underpart is provided with and institute
The internal thread that lower body of rod upper end coordinates is stated, its top is provided with the internal thread coordinated with the spill spin block.
Further：The lower body of rod is the pipe body that one end is provided with a mouth provided with opening, the other end, in the lower body of rod
Inside is provided with platform, and the platform is provided with groove, and the telescopic protective cover is connected in the groove.
Further：The telescopic protective cover is made of plastics.
Further：The pencil-lead positioning sleeve is provided with salient point by plastic production, its endoporus.
By adopting the above-described technical solution, the present invention has the advantages that compared with prior art：
1st, the present invention is made up of at the top of a dismountable pencil shaft, the upper body of rod provided with a rotation the upper body of rod and the lower body of rod
Block, spill spin block is connected through a screw thread with the upper body of rod, and spill spin block connects a depression bar, and depression bar directly pushes down pencil-lead afterbody, pencil
Provided with a telescopic protective cover outside core, lower post mouth a, mouth stretches out hole provided with a pencil-lead, stretches out and is provided with hole
Pencil-lead positioning sleeve, pencil-lead fractures caused by firmly excessive when effectively can prevent from writing；
2nd, the present invention is simple in construction, easy to use, the length that can arbitrarily control pencil-lead to be stretched out from a mouth.
Brief description of the drawings
Fig. 1 is the front view of the present invention.
Embodiment
The present invention is further described with reference to the accompanying drawings and examples：
A kind of cutting-free pencil penholder core penholder as shown in Figure 1, including the upper body of rod 2 and the lower body of rod 4 that one end is flexibly connected, on
The body of rod 2 is pipe body, and its underpart is provided with the internal thread coordinated with the upper end of the lower body of rod 4, and the upper end of the lower body of rod 4 is provided with external screw thread,
In other embodiments, the upper body of rod 1 can also be set to external screw thread, the lower body of rod 4 sets internal thread, and principle is ibid；The top of the upper body of rod 2 is set
There is the internal thread coordinated with spill spin block 1；The top of the upper body of rod 2 has been connected through a screw thread spill spin block 1, the bottom connection of spill spin block 1
There is depression bar 3；Pencil-lead 8 is installed, the outside of pencil-lead 8 is provided with telescopic protective cover 5, protection of stretching between depression bar 3 and the lower body of rod 4
The upper end of set 5 is abutted with the lower end of depression bar 3, and its lower end is abutted with the platform of the lower bottom of the body of rod 4, to ensure that depression bar 3 is pushed down all the time
The upper end of telescopic protective cover 5 and pencil-lead 8, can set a cylindrical cap below depression bar 3, and the internal diameter of cylindrical cap is slightly larger than
The diameter of telescopic protective cover 5；The lower body of rod 4 is the pipe body that one end is provided with a mouth 6 provided with opening, the other end, and a mouth 6 is provided with pencil
Core stretches out hole, and platform 7 is provided with inside lower beam body, and platform 7 is provided with groove, and telescopic protective cover 5 is connected in groove, protection of stretching
Set 5 is made of plastics, and telescopic protective cover 5 can be compressed, and the bottom of the lower body of rod 4 is provided with a mouth 6, and a mouth 6 is stretched provided with pencil-lead
Portal, pencil-lead, which stretches out, is provided with pencil-lead positioning sleeve 9 in hole, pencil-lead positioning sleeve 9 is made by flexible materials such as plastics, this implementation
In example, pencil-lead positioning sleeve 9 is manufactured by elastomeric material, and its endoporus is provided with micro convex point, and the diameter of bore of pencil-lead positioning sleeve 9 is bigger
In the diameter of pencil-lead 8, micro convex point ensures that pencil-lead 8 has certain resistance in pencil-lead positioning sleeve 9, prevent pencil-lead 8 from
Pencil-lead positioning sleeve 9 is dropped out.
In use, when pencil-lead 8 is not enough from the extending port exposed portion of a mouth 6, spill spin block 1 can be turned, spill spin block 1 to
Lower movement simultaneously drives depression bar 3 top pencil-lead 8 and telescopic protective cover 5 downwards, and telescopic protective cover 5 shortens after being pressed, and pencil-lead 8 is pressed
Ejected afterwards from the outlet of a mouth 6；If the exposed portion of pencil-lead 8 is long, spill spin block 1 can be reversely twisted, then by pencil-lead 8 toward returning back to top
；Especially, also the exposed length of pencil-lead 8 can be ejected by rotating the upper body of rod 2 and the lower body of rod 4.
