Abstract

The utility model provides a helical pushing-pulling-pressing type sandwich-core multiple purpose pen, relating to a writing and drawing tool. The utility model is composed of a pen body and a pen head provided with a pen-core clamping mechanism, wherein, the pen-core clamping mechanism comprises an outer sleeve, a clamping head and a screw rod which are arranged inthe outer sleeve, and a pen neck and a rotary cap which are arranged at the two ends of the outer sleeve; the clamping head is connected with the screw rod by screw thread. Due to the adoption of the helical pushing-pulling-pressing type cone clamping device, the utility model has the advantages of short length, large clamping force, strong stableness of the pen core, wide variation range of clamping diameters, etc., and is widely applied to the fields of writing, drawing, painting, characters carving, etc.

Description

Helical pushing-pulling-pressing type sandwich-core multiple purpose pen

The utility model relate to a kind ofly write, drawing instrument.

Existing propelling pencil specification is various, the pen core that can only use a kind of soft durometer that has, thereby can not satisfy the selection requirement of people to the pencil specification performance; Although the pen core that can replace different size that has exists clamping vary in diameter narrow range, folder power deficiency, the defective of pen core steadiness difference, and they write all more singlely, use inconvenient.

The purpose of this utility model is to provide a kind of clamping vary in diameter scope big, and the pen core steadiness is strong, novel spiral push-press type sandwich Writing-painting pen easy to use.

Spiral push-press type sandwich multipurpose pencil is made up of handwriting and the nib that the pen core clamping mechanism is housed.

Below in conjunction with embodiment shown in the drawings primary structure of the present utility model and using method are elaborated.

Accompanying drawing is the utility model front view.Among the figure (water-color paintbrush does not cut): 1. pen core, a 2. item, 3. chuck, 4. overcoat, 5. screw rod, 6. turncap, 7. penholder, 8 water-color paintbrushes, 9. the pen cap 10. digs the core cutter.

A kind of spiral push-press type sandwich multipurpose pencil is made up of handwriting and the nib that the pen core clamping mechanism is housed.The pen core clamping mechanism comprises overcoat 4 and dress chuck 3 and screw rod 5 within it, is contained in the pen item 2 of overcoat 4 front ends and is contained in the turncap 6 that is linked together with screw rod 5 outside overcoat 4 rear ends; Chuck 3 is used thread connection with screw rod 5.

Pen item 2 is the cones that are formed from steel, and anterior interior external taper is 23 °, and thread connection are adopted with overcoat 4 in the rear portion.

The front portion of chuck 3 is a jaw, the middle part is a reed, the rear portion is the guide way of outer-hexagonal nut form, and be provided with axially extending bore and internal thread, one end of screw rod 5 is provided with external screw thread, matches with chuck 3 guide waies, and there is an outward flange centre, the other end be Cylinder and pass overcoat 4 inward flanges and turncap 6 fastening, also be provided with axially extending bore in it.When rotating turncap 6, stop screw rod 5 to move backward by two interior outward flanges.

Handwriting comprise penholder 7, water-color paintbrush 8, the pen cap 9, penholder 7 one ends make in Hexagonal jacket match with turncap 6, the other end of penholder 7 stores up the core tube with thread connection water-color paintbrush 8, the handwriting double as of penholder 7; The pen cap 9 tops have cavity; Digging core cutter 10 is inserted in the pen cap 9 cavitys.

Operation principle of the present utility model is such: when rotation penholder 7 or turncap 6, the screw rod 5 that rotates promotes chuck 4 moving linearlies, when chuck 4 when pen item 2 directions move, taper pen item 2 forces the jaw on the chuck 3 to clamp pen core 1, when chuck 3 leaves pen 2, because the elasticity of reed itself in the chuck 3, jaw unclamps pen core, thereby makes the pen core 1 of various models, ballpoint pen core obtain replacing.The pen core 1 of all size can be stored in the core tube.

The advantages such as obviously, the utility model has adopted helical pushing-pulling-pressing type conical surface clamping device, and it is short to have length, and chucking power is big, and the pen core steadiness is strong, and the excursion of clamping diameter is wide. Add on the handwriting band just like the functor of water-color paintbrush and so on, applicability is wider, uses more conveniently, can be widely used in fields such as writing, draw, paint, carve characters.
