Abstract

The utility model relates to a universal ball pen which can change the ball pen cores of various sizes and is composed of a pen handle provided with an adjustment positioning slot, a pen handle head, a tail cap, an elastic positioning post, a positioning rod, a button, an elastic clamp head and a return spring. The pen can change the various ball pen cores of different lengths and diameters used at the prior market. The utility model has simple structure, convenient change and low cost and solves the problem that the prior ball pen sold at the market can only change the pen core with the same size.

Description

Universal ball pen

The utility model is a kind of omnipotent garden pearl pen that relates to replaceable multiple different length, different-diameter garden pearl pen core.

The garden pearl pen that at present domestic and international manufacturer is produced is various in style, but weak point is to change the garden pearl pen core of specification of the same race, can't change that diameter is identical, length is different or length is identical and the garden pearl pen core of other plurality of specifications that diameter is different, have to abandon less than identical pen core need not because of joining for a lot of people, other purchases new pen, and many units also are so, and this all is a kind of waste to country, individual, China region is wide, and this phenomenon is particularly outstanding in remote districts.

The purpose of this utility model is exactly in order to address the above problem, and a kind of replaceable multiple different size garden pearl pen core is provided, and is simple in structure, and can make the omnipotent garden pearl pen in the pen core retraction penholder.

The said omnipotent garden of the utility model pearl pen is made of penholder, pen head, tail cap and keeper, it is characterized in that it is by the penholder 1 that has an adjusting locating slot 7 and the pen head 9 and the tail cap 10 that flexibly connect with its two ends, can allow elasticity fixed column 4 that garden pearl pen core afterbody inserts and can move penholder 1 in, can with regulate locating slot 7 the coincide backstays 5 that location and dislocation move, the push button 6 that can make backstay 5 location or move, be installed in clamping garden pearl pen core heads in the pen head 9 and mobile collet 2 and be enclosed within return spring 8 compositions outside it.

Fig. 1 is a front view of the present utility model.Fig. 2 is the cutaway view of Figure 1A-A line.

The utility model is further described by embodiment below in conjunction with accompanying drawing.

The two ends of penholder 1 are useful on the annular concave-convex 12 that flexibly connects pen head 9 and tail cap 10, the adjusting locating slot 7 that penholder 1 vertically has one one end to connect, and this trough rim is along the sawtooth that location usefulness is arranged.Pen head 9 one ends have the annular concave-convex 12 that flexibly connects with penholder 1, and the other end has a hole that can allow collet 2 thin ends freely come in and go out.Elasticity reference column 4 in the penholder 1 is connected as one by the push button 6 outside backstay 5 and the penholder 1, elasticity reference column 4 is a piston-like, in the middle of it garden platform cavity 13 is arranged, backstay 5 one sides have sawtooth, and the tooth pitch and the width of the tooth pitch of this sawtooth and width and adjusting locating slot 7 match.Collet 2 in the pen head 9 is a thin-walled stairstepping garden post, its thin end has one to connect breach 3, and butt end has several perforation breaches that this end is divided into petal-shaped, and every lobe vertically is wavy, every lobe head all has outside flanging 11, and return spring 8 is installed in the butt end outer end and is stuck in the flanging 11.

Pull up pen head 9 from penholder 1, the ferrule of garden pearl pen core is inserted in the collet 2, because vertically having of collet 2 connects breach 3, also can spreading collet 2 when ferrule and charge of oil pipe diameter are thick, pressing push button 6 misplaces the sawtooth of backstay 5 one sides and the sawtooth of regulating on locating slot 7 edges up and down, backstay 5 is elasticity of compression reference column 4 slightly, push button 6 moves down and can drive the lower end that elasticity fixed column 4 moves down into penholder 1, garden pearl pen core afterbody is inserted in the elasticity reference column 4, pen head 9 can be inserted in the penholder 1 after loading onto pen core, when pressing push button 6, the outer return spring 8 of collet 2 butt ends is upheld and is promptly driven collet 2, move on pen core and the elasticity reference column 4, in pen core ferrule retraction pen head 9, pressing push button 6 during use misplaces the sawtooth of backstay 5 one sides and the sawtooth of regulating on locating slot 7 edges up and down, promote push button 6 drive backstay 5 elasticity reference columns, 4 pen cores and collet 2 and move down also compression recovery spring 8, the thin end of collet 2 and pen core ferrule are stretched out outside the aperture at pen head 9 tips, decontrol push button 6, backstay 5, elasticity reference column 4, down outer the moving of recuperability effect, the sawtooth of backstay 5 one sides with adjust sawtooth on locating slot 7 edges location that coincide.The penholder 1 of the foregoing description also can be connected as a single entity with pen head 9, and collet 2 and return springs 8 in the pen head 9 are saved, and the garden pearl pen core of different size also can be installed and can normally use.

The utlity model has following advantage: its structure is simpler than the garden pearl pen of existing collapsible pen core, serviceability is reliable, and is not easy to failure, can change easily multiple different size garden pearl pen core, expand the use function of garden pearl pen, had more stronger practical popularity.
