The invention discloses a kind of portable telescopic pen, including front pen tube, rear pen tube, rear tooth bar, front tooth bar, driving member, gear and pen core, front pen tube is the pipe of variable diameters, rear end pipe diameter is less than front end pipe diameter, front tooth bar front end is connected with pen core rear end, rear pen tube is stretched in rear tooth bar rear end, and be connected with rear pen tube inwall, gear is arranged on driving member, front tooth bar is arranged on driving member top, and engage with gear, rear tooth bar is arranged on bottom driving member, and engage with gear, front pen tube is stretched in driving member front end, and be connected with front pen tube, pen core is arranged in front pen tube；When front pen tube and rear pen tube close up, rear pen tube is enclosed within the rear end that front pen tube diameter is little.The present invention reduces the assembling parts of pen, when state is write in needs entrance, by two shafts of a writing brush of stretching, can write, then can be shrunk to the length of a medicated cigarette when non-writing state, save space, it is simple to carry.
Description
Technical field
The invention belongs to stationery, particularly relate to a kind of portable telescopic pen.
Background technology
Pen, is a great invention of the mankind, is the instrument for writing or paint, and the nibs that pass through will carry coloured more
Solid or liquid (ink) are on paper or other surfaces of solids draw word, symbol or picture, also have and utilize the hard of solid nib
Degree writes picture pencil and charcoal pencil.With ink, paper, inkstone claim the writing brush, ink stick, ink slab and paper.Along with the development of society, the kind of pen is the most increasingly
Many, commonly use now is gel ink pen and ball pen.The most most pen, has longer penholder, is either placed in
In the petite portable package of Ms or the pocket of man style, the most inconvenient.Although the pen of some small volume is easy to carry,
But to the when of really used by people, it is strong that user can feel to grasp sense, is unfavorable for writing.
Summary of the invention
It is an object of the invention to provide a kind of portable telescopic pen, when state is write in needs entrance, by stretching two
The shaft of a writing brush, can write, and then can be shrunk to the length of a medicated cigarette when non-writing state, saves space, it is simple to carry.
The technical solution realizing the object of the invention is: a kind of portable telescopic pen, including front pen tube, rear pen tube, rear tooth
Bar, front tooth bar, driving member, gear and pen core, front pen tube is the pipe of variable diameters, and rear end pipe diameter is straight less than front end pipe
Footpath, front tooth bar front end is connected with pen core rear end, and rear pen tube is stretched in rear tooth bar rear end, and is connected with rear pen tube inwall, and gear is arranged
On driving member, front tooth bar is arranged on driving member top, and engages with gear, and rear tooth bar is arranged on bottom driving member, and and tooth
Wheel engages, and front pen tube is stretched in driving member front end, and is connected with front pen tube, and pen core is arranged in front pen tube；Front pen tube and rear pen tube
When closing up, rear pen tube is enclosed within the rear end that front pen tube diameter is little.
Described driving member is strip, and its top and bottom have groove along its length, and rear tooth bar is arranged on the end
In first groove in portion, front tooth bar is arranged in first groove at top, all can slide along the first groove, said two first
Having through hole between groove, gear is arranged in described through hole, engages with rear tooth bar and front tooth bar respectively, and driving member rear end has
Second groove, the end face of the described second through driving member of groove and bottom surface.
Described rear tooth bar and the front tooth bar direction of motion are contrary.
Described rear tooth bar rear end is provided with projection, when front pen tube and rear pen tube close up, and described projection and above-mentioned second groove
Coordinate location.
Described driving member also includes alignment pin, and the circular tube external wall symmetry that front pen tube diameter is big has two strip through holes,
Alignment pin sequentially passes through a strip through hole, gear and another strip through hole, and limiting gear rotates, thus to pen core
Extension elongation positions.
The present invention compared with prior art, its remarkable advantage:
(1) length of a medicated cigarette it is contracted in non-writing state, it is simple to user carries.
(2) decrease the assembling parts of pen, both saved pen cap material, reduce manufacturing cost, turn avoid use process
The loss of middle pen cap parts.
(3) the small and exquisite exquisiteness of moulding, can close in the little satchel of Ms, can be placed on again in the Western-style clothes pocket of man style, significantly
Open up market.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
In conjunction with Fig. 1 to Fig. 5, a kind of portable telescopic pen, including front pen tube 1, rear pen tube 2, rear tooth bar 3, front tooth bar 4, transmission
Part 5, gear 6 and pen core 7, front pen tube 1 is the pipe of variable diameters, and rear end pipe diameter is less than front end pipe diameter, before front tooth bar 4
End is connected with pen core 7 rear end, and rear pen tube 2 is stretched in rear tooth bar 3 rear end, and is connected with rear pen tube 2 inwall, and gear 6 is arranged on transmission
On part 5, front tooth bar 4 is arranged on driving member 5 top, and engages with gear 6, and rear tooth bar 3 is arranged on bottom driving member 5, and and tooth
Wheel 6 engages, and front pen tube 1 is stretched in driving member 5 front end, and is connected with front pen tube 1, and pen core 7 is arranged in front pen tube 1；Front pen tube 1 He
Rear pen tube 2-in-1 hold together time, rear pen tube 2 is enclosed within the rear end that front pen tube 1 diameter is little.Driving member 5 front end can arrange connector, for front
The shaft of a writing brush 1 inwall is connected.
Described driving member 5 is strip, and its top and bottom have groove along its length, and rear tooth bar 3 is arranged on
In first groove of bottom, front tooth bar 4 is arranged in first groove at top, all can slide along the first groove, said two
Having through hole between first groove, gear 6 is arranged in described through hole, engages with rear tooth bar 3 and front tooth bar 4 respectively, driving member 5
Rear end has the second groove, the end face of the described second through driving member of groove 5 and bottom surface.Described rear tooth bar 3 and front tooth bar 4 move
In opposite direction.
Described rear tooth bar 3 rear end is provided with protruding 8, when front pen tube 1 and rear pen tube 2-in-1 hold together time, described protruding 8 and above-mentioned second
Groove fit positions.
Described driving member 5 also includes alignment pin, and the circular tube external wall symmetry that front pen tube 1 diameter is big has two strips and leads to
Hole, alignment pin sequentially passes through a strip through hole, gear 6 and another strip through hole, and limiting gear 6 rotates, thus right
The extension elongation of pen core 7 positions.
When front pen tube 1 and rear pen tube 2-in-1 hold together time, pen core 7 is contracted in front pen tube 1, can be positioned by alignment pin, prevents from grasping by mistake
When making, pen core 7 exposes.When needing use, alignment pin is resetted, pull front pen tube 1 and rear pen tube 2, tooth bar after rear pen tube 2 drive
3 rearward movement, and then gear 6 rotates, before driving, tooth bar 4 travels forward so that pen core 7 stretches out from front pen tube 1, according to need
Want, after arriving suitable length, locking positioning pin, position.
