Description
Technical field
The utility model relates to a kind of stationery, and more particularly, it relates to a kind of two-headed pen.
Background technology
At present, on the market gel ink pen be all, in one-pen cylinder, one-pen core is housed, can only write out a kind of font of color, purposes is more single.But many times people have different demands, needing to be distinguished in font, needing to be distinguished emphasis as student conveniently reviews when taking notes, clerk needs when writing and revise manuscript to distinguish amendment part etc.Gel ink pen can not meet the demand of working and learning in these cases.
Application number is that the Chinese patent of 201220190873.X discloses and a kind of two writes pen, it comprises a body, Anti-slip cover, cap, nib, described body can be various three-dimensional shape, two Anti-slip covers are enclosed within a body both sides respectively, two caps cover at body two respectively, the pen core direction of two different colours can be put in double-core pen body.Although this pair is write pen and can meet the demand distinguished in font, use makes pen revolve turnback, but cap is in long-term use procedure, cap can slowly fluff, make cap to be firmly enclosed within it pen, easily lose, pen core will be made so out exposed, easily because of the design of double end, pen core upward can be drawn people or falls on the ground and broken by pen core and cannot continue to use.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of can not draw user and the two-headed pen placing that pen core breaks when not using.
For achieving the above object, the utility model provides following technical scheme: a kind of two-headed pen, comprise penholder, be threadedly connected to the nib at penholder two ends, two pen cores oppositely placed are provided with in described penholder, be provided with the fixed mechanism for fixing pen core in described penholder, described penholder be provided with the driving mechanism driving pen core to stretch in nib.
The utility model is set to further: described fixed mechanism is fixed head, and described fixed head is provided with two reverse tanks, two cell walls of described tank are provided with the projection for clamping pen core, and described pen core is placed in tank.
The utility model is set to further: described driving mechanism is made up of through hole, drive block and flexure strip, described through hole is arranged on penholder, described drive block is fixedly connected with fixed head through through hole, and described flexure strip to be arranged on fixed head and away from the side of drive block.
The utility model is set to further: through hole is provided with the first breach, the second breach and the 3rd breach side by side along penholder direction, described first breach, the second breach are all identical with the 3rd notch geometry size, described drive block are provided with the locating piece with the first breach adaptation.
Compared with prior art, the utility model has the advantage of: by the tank arranged on fixed head, and on two cell walls of tank, projection is set, make pen core being placed in tank and can being clamped by arranging of projection, pen core can not be come off, can move together along with the movement of fixed head, make drive block drive locating piece mobile to penholder inside by pressing drive block simultaneously, locating piece is made to depart from the first breach, flexure strip is now because drive block is to moving and make fixed head be compressed in penholder, flexure strip is extruded and there is elastic-restoring force, drive block is moved to the second breach direction, and remove active force, its locating piece just can be embedded into the second breach being subject to the elastic-restoring force of flexure strip, fixed head cannot be moved, in like manner locating piece can be moved to the 3rd breach, these three breach are that the other end is exposed in penholder or the regulation stall of two pen cores all in penholder in one end of pen core, by such setting, the pen core at two can be exposed use that the other end will be made to be in penholder is inner and can not scratch user in one end, make not using, drive block is moved to the second breach, two pen cores just can be made all to be in penholder, to protect pen core, can not to be broken.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model two-headed pen embodiment is described further.
A kind of two-headed pen, comprise penholder 1, be threadedly connected to the nib 2 at penholder 1 two ends, be provided with two pen cores 3 oppositely placed in described penholder 1, in described penholder 1, be provided with the fixed mechanism for fixing pen core 3, described penholder 1 is provided with the driving mechanism driving pen core 3 to stretch in nib 2.
Described fixed mechanism is OBL fixed head 4, described fixed head 4 is provided with two reverse tanks 41, described tank 41 is adaptive with pen core 3, two cell walls of described tank 41 are provided with the projection 42 for clamping pen core 3, described projection 42 is set to square, and described pen core 3 is placed in tank 41.
Described driving mechanism is made up of through hole 5, drive block 6 and flexure strip 7, described through hole 5 is set to oblong-shaped, described through hole 5 is arranged on penholder 1, described drive block 6 is fixedly connected with fixed head 4 through through hole 5, described flexure strip 7 to be arranged on fixed head 4 and away from the side of drive block 6, described drive block 6 is set to oblong-shaped, and described flexure strip 7 is made up of plastics, and has certain elastic deformation and elastic-restoring force.
Through hole 5 to be provided with along penholder 1 direction the first breach 51, second breach 52 side by side and the 3rd breach 53, described first breach 51, second breach 52 is all identical with the 3rd breach 53 shape size, the shape of described first breach 51 is square, described drive block 6 is provided with the locating piece 61 with the first breach 51 adaptation.
