Description

Flexible rod-type ball pen

The utility model relates to a kind of writing appliance, specifically a kind of flexible rod-type ball pen.

Old-fashioned ball pen is made up of penholder, pen core and end cap, and the ball-point pen tip of pen core is exposed at outside the penholder, pollutes article such as pocket, pencil box easily.Improved ball pen is the telescopic form of a kind of pen core, and its structure is to be installed with pen core in penholder, the bottom cutting ferrule spring of pen core, and pegging graft and push up cover, a card mechanism and end cap etc. in the upper end of pen core, is shaped on convex and continues to use to cooperate a card mechanism on penholder.Push end cap, then the top cover presses down pen core, and a card mechanism is stuck on the interior convex edge of penholder, and nib can expose outside the penholder like this, for the usefulness of writing.After using up, push end cap once more, a card mechanism is got loose, pen core is pushed up back in the penholder under the rebound effect of spring.No matter be put into this ball pen the there this moment again, then all do not have having considered that a greasy dirt dyes.Though this ball pen has solved the flexible problem of nib, use also to show slightly trouble, promptly after using up, also need to turn penholder, push end cap, nib could bounce back.Also need before the use to push end cap earlier, make nib expose the location after, turn penholder again, hold the pen to pen holding posture, just can write.

The purpose of this utility model just provides and a kind ofly need not to turn the flexible rod-type ball pen that penholder can the turnover of direct regulation and control nib under the state of holding a pen writing, so that provide maximum facility for the user.

The utility model is achieved in that flexible rod-type ball pen still is made up of parts such as penholder, pen cores, in penholder, be installed with pen core, the bottom cutting ferrule spring of pen core, institute's improvement is to be covered with sleeve pipe in the bottom of penholder, in the penholder bottom elastic button is housed, the perforate of cutting ferrule button is arranged on the sleeve pipe, and following Taper Pipe is screwed in the end opening of sleeve pipe.Sleeve pipe and following Taper Pipe are combined into the gripping shaft of a writing brush of writing pen.After having held the shaft of a writing brush, forefinger that holds a pen and middle finger are clamped shaft of a writing brush retraction, and thumb clamps with tiger that penholder is relative exerts oneself, and can make the relative penholder retraction of the shaft of a writing brush, and elastic button heads in the perforate of sleeve pipe automatically, block the shaft of a writing brush and locate, and nib is stretched out, and directly write.Write completely, point is pressed the button top, makes button break away from casing pipe hole opening, and the recoil of spring on the pen core rebounds the shaft of a writing brush, and the end opening of following Taper Pipe shelters from nib again.This mode of operation has realized the flexible of ballpoint holder, uses very simple and conveniently, need not turn the turnover that penholder can be controlled pen core, so provides the facility of writing for numerous users.Because the shaft of a writing brush is thicker, is convenient to grip and writes simultaneously, also solved the problem that ballpoint holder is thin, inconvenience grips thus.

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

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the A-A of Fig. 1 is to cutaway view.

As shown in Figure 1, penholder of the present utility model becomes two bodies, promptly is made up of the penholder 7 and the shaft of a writing brush.The shaft of a writing brush is spun by sleeve pipe 3 and following Taper Pipe 6 and forms.The bottom of penholder 7 is thick slightly, closes up in the top of sleeve pipe 3, earlier the upper end of penholder 7 end opening from sleeve pipe 3 is penetrated, and sleeve pipe 3 is fastened on the penholder 7.Pen core 2 is penetrated in the penholder 7, and the bottom wears spring 5, will descend Taper Pipe 6 to be screwed in the end opening of sleeve pipe 3 again, ball pen can be assembled.But when assembling sleeve pipe 3 and penholder 7, elastic button 4 is installed earlier, and make in its perforate that is fastened in sleeve pipe 3, just can carry out the assembly operation of bottom then.

For preventing rotation because of sleeve pipe 3, button 4 can not be snapped in the casing pipe hole opening exactly, as shown in Figure 1, 2, one side has projection in penholder 7 bottoms, there is a pit at the boss place, spring and button 4 are housed in the pit, form elastic button, the groove that matches with the penholder projection is arranged at the inwall of sleeve pipe 3.Like this, sleeve pipe 3 just can only move forward and backward in the matching track of groove and projection, and lateral rotation can not take place.

Among Fig. 1, the top of penholder 7 can be made into the form of opening, is connected with end cap 1 on penholder 7 tops, is fixed with pen hanging 8 between end cap and penholder, with convenient ball pen is hung in the pocket.
