Description

Movable universal replaceable pencil

Technical field

The utility model relates to a kind of movable replaceable pencil, especially for the replaceable pencil of different-diameter pen core.

Background technology

At present, a movable replaceable pencil can only use a kind of pen core of diameter, as used the pen core of multiple diameter to need to be equipped with the movable replaceable pencil of many moneys, and very inconvenience.

Summary of the invention

The purpose of this utility model is for prior art above shortcomings, and a kind of movable universal replaceable pencil is provided, and it can use the pen core of multiple diameter, and clamps firmly, has advantages of that versatility is good, easy to use.

For achieving the above object, the movable universal replaceable pencil of one of the present utility model, comprise nib, the shaft of a writing brush and the cap for brush, in the shaft of a writing brush, be connected with seat pipe, in seat pipe, be provided with step, what seat slided in managing is provided with core storage tube, core storage tube overcoat has the spring of axial location, spring is positioned at the seat pipe at step rear, the cap for brush is placed on the rear end of core storage tube, and described nib is conical tube, and nib is connected with seat pipe by the internal thread of rear end, it is characterized in that written front end is provided with the axial groove of one or more, is also connected with regulating sleeve by the external screw thread on taper seat at written front end.

When use, the shaft of a writing brush is tilted, presses the cap for brush, the pen core in core storage tube slides and enters in nib, in the time that the front end of pen core stretches out nib, rotate regulating sleeve, written front end is shunk, pen core is clamped, the pen core of different-diameter is all suitable for, has advantages of that versatility is good, easy to use;

As further improvement of the utility model, in the written front end between axial groove, also connect firmly metal intermediate plate; Nib is generally working of plastics, and the intensity of metal intermediate plate is better, and clamping pen core is more firm, conveniently writes;

As further improvement of the utility model, the seat bore in described step front is greater than step place internal diameter, and the front end of core storage tube is positioned at step front, and the front end external diameter of core storage tube is greater than step place internal diameter; Can position the return of core storage tube;

In sum, the utility model can use the pen core of multiple diameter, and clamping firmly, has advantages of that versatility is good, easy to use.

Fig. 2 is the front view of nib in Fig. 1.

Fig. 3 is the left view of Fig. 2.

Detailed description of the invention

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As Fig. 1, Fig. 2, shown in Fig. 3, this movable universal replaceable pencil, comprise nib 1, the shaft of a writing brush 2 and the cap for brush 3, in the shaft of a writing brush 2, be threaded connection seat pipe 4, in seat pipe 4, be provided with step 5, the 4 interior slips of seat pipe be provided with core storage tube 6, core storage tube 6 overcoats have spring 7, the outer projection 8 that is provided with of core storage tube 6, in the seat pipe 4 of spring 7 between step 5 and projection 8, realize the axial location of spring 7 by step 5 and projection 8, seat pipe 4 internal diameters in described step 5 fronts are greater than step place internal diameter, the front end of core storage tube 6 is positioned at step 5 fronts, the front end external diameter of core storage tube 6 is greater than step place internal diameter, the cap for brush 3 is placed on the rear end of core storage tube 6, described written 1 is conical tube, nib 1 is connected with seat pipe 4 by the internal thread of rear end, nib 1 front end is provided with three uniform axial grooves 9, also be connected with regulating sleeve 10 by the external screw thread on taper seat at written 1 front end, in nib 1 front end between axial groove 9, also connect firmly three metal intermediate plates 11, .

When use, the shaft of a writing brush 2 is tilted, presses the cap for brush 36, the pen core in core storage tube slides and enters in nib 1, in the time that the front end of pen core stretches out written 1, rotates regulating sleeve 10, written 1 front end is shunk, and by metal intermediate plate 11, pen core is clamped; Because the utility model can make nib 1 shrink within the specific limits by regulating sleeve 10, the pen core of different-diameter is all suitable for, only need take off the cap for brush 3, in core storage tube 6, pack the pen core of different-diameter into, have advantages of that versatility is good, easy to use; Metal intermediate plate clamping pen core is more firm, conveniently writes; The front end of core storage tube 6 can position the return of core storage tube.

The utility model is not limited to above-mentioned embodiment, as spring sets firmly chuck outward, by chuck, spring is carried out to axial location, and the quantity of written front end axial groove also can be one or two, and they all fall into the protection domain of this patent.
