Description

Rock type thick core sharpening propelling pencil

The utility model relates to a kind of propelling pencil.

At present, domestic and international existing propelling pencil all is that lead for retractable pencil is put into a chamber, and by pushing the button behind the pen, a section comes out to make lead for retractable pencil.All there is the problem of some in such push button propelling pencil: because structural reason, the strength of pushing button needs very big sometimes, and that the chief drawback is is always long by the lead for retractable pencil that comes out, write, easy to break when fining away, cause waste, long after often with lead for retractable pencil again by going back, bring a lot of inconvenience to people.

At problem set forth above, the utility model proposes a kind of rock type thick core sharpening propelling pencil, its purpose be to solve the push button propelling pencil go out plumbous long, use inconvenience, existing problem easy to break.

The utility model is achieved through the following technical solutions:

Rock type thick core sharpening propelling pencil, it includes lead for retractable pencil, penholder, it is characterized in that: the rear portion with lead for retractable pencil in the cavity of penholder is provided with a hammer body, front portion at penholder is provided with elastic ring, Casing with pen is on lead for retractable pencil, elastic ring contacts mutually with pen clip, the sleeve pipe that it is the inclined-plane that the periphery of pen clip is provided with an inside.

By isolation bar a chamber is separated into two chambeies, front and back in penholder, isolation bar is provided with leads plumbous hole; Hammer body is arranged in the back cavity, and the position that leans against isolation bar in ante-chamber is provided with stud, and the end of pen clip is a slope shape.

Fix a sleeve pipe in the ante-chamber of pen, pen clip is spacing in sleeve pipe by ball.

End at penholder is provided with a sharpener, is plugged in the shaft of a writing brush.

The utility model has the advantages that to have solved as the push button propelling pencil to go out plumbous shortcoming long, easy to break, avoid causing waste, this pen not power of costing is pressed, and only need shake penholder gently can go out lead, easy to use, heightens the enjoyment again.In addition, it is also very convenient that this propelling pencil changes lead, need not resemble to pin button the push button propelling pencil always and just can change lead, just this pen only need with nib rotate an angle go out plumbous when as, promptly replaceable.

Accompanying drawing 1 is for having the overall structure schematic diagram of the present utility model of sleeve pipe;

Accompanying drawing 2 is not for having the overall structure schematic diagram of the present utility model of sleeve pipe;

Accompanying drawing 3 is a longitudinal sectional drawing of the present utility model;

Accompanying drawing 4 is the longitudinal sectional drawing of the utility model sleeve pipe;

Accompanying drawing 5 is the structural representation of the utility model isolation bar cross section;

Accompanying drawing 6 is the structural representation of the utility model pen clip;

Accompanying drawing 7 is the upward view of the utility model pen clip;

Accompanying drawing 8 is the structural representation of the utility model sharpener.

The utility model is specifically described by embodiment below in conjunction with accompanying drawing:

As shown in Figure 2, the interior cover of penholder 2 of the present utility model can be the inclined-plane, can be sleeve pipe 8 replacements on inclined-plane with inside also.

As shown in Figure 1, the utility model is divided into former and later two cavitys by isolation bar 6 with penholder 2, has on the isolation bar 6 to lead plumbous hole, and hammer body 3 is arranged in the rear chamber, can move.In the ante-chamber of propelling pencil, fix a sleeve pipe 8, the inside of sleeve pipe 8 is the inclined-plane, and pen clip 5 is spacing in sleeve pipe 8 by ball 9, and pen clip 5 is enclosed within on the lead for retractable pencil.Pen clip 5 is subjected to the longitudinal force of elastic ring 4, under the effect of pen clip 5 and ball 9 and sleeve pipe 8, produces a cross force lead for retractable pencil 1 is clamped; The position-limiting action of ball 9 is to make pen clip 5 be in the position that lead for retractable pencil 1 is clamped.Shake penholder 2, hammer body 3 knocks lead for retractable pencil 1 and moves forward, because coefficient of rolling friction is less than the coefficient of sliding friction, make pen clip 5 and lead for retractable pencil 1 relative position constant, pen clip 5 moves forward with lead for retractable pencil 1, can open after lead for retractable pencil 1 pen clip 5 moves forward but hold, the relative position of lead for retractable pencil 1 and pen clip 5 changes like this, and lead for retractable pencil 1 moves forward a little distance.Be provided with elastic ring 4 in the front portion of penholder 2, elastic ring 4 adopts spring or damped ring etc. to have the device of elastic construction.After pen clip 5 moves forward, under the effect of elastic ring 4, get back to original position, pen clip 5 hangs on to lead for retractable pencil 1 once more, makes pencil lead for retractable pencil 1 unlikely being withdrawn in the penholder 2 when writing.Because the displacement of lead for retractable pencil 1 is very little, thereby has solved the push button propelling pencil and gone out the plumbous long waste that causes.

Isolation bar 6 is provided with stud 7, and in writing at ordinary times, pen clip 5 withstands on the isolation bar 6, when needs are changed lead for retractable pencil 1, and angle of nib rotation, pen clip 5 moves forward, and withstands on the stud 7, and pen clip 5 opens, and lead for retractable pencil 1 can be changed.Rotate an angle after the replacing again, under the effect of elastic ring 4, pen clip 5 moves backward, and pen clip 5 is held lead for retractable pencil 1 once more, makes lead for retractable pencil 1 unlikely being withdrawn in the penholder 2 when writing.The afterbody of pen clip 5 is slope shape or semi-circular, and is slicker and more sly, easier when the rotation nib is changed lead like this.

Sharpener 10 is inserted in the afterbody of penholder 2, and the top of sharpener 10 is provided with leads plumbous hole, its have one with axis direction knife rest at angle, blade is fixed on the knife rest.During assembling, cutter is inserted in the groove of having established on the sharpener 10 gets final product.
