As shown in Figure 1, beam barrel 1 leading section has screwed togather a precentrum 2 removably, forwards is formed with a pair of rib 1a (fitting portion) that leads at the beam barrel inwall by the rear end, and this is led rib 1a and is provided with as Fig. 3 to slidably saddle 3 shown in Figure 5.

The formation of saddle 3 be by, be limited to handle hole 1b (as shown in Figure 2) end of beam barrel 1 sidewall be reverse U shape (as shown in figure 12) pressing member (control member), make inclined plane part 3a, the chuck linking part 3b that is pressed into chuck that saddle 3 advances, hold the 3d of portion in abutting connection with the rear end of the minor diameter part 3 of inclined plane part 3a, the minor diameter part 3c that continues, and saddle 3 outer walls form along its length with beam barrel 1 inwall lead the chimeric guide channel 3e of rib 1a.

The chuck linking part 3b inside of saddle 3 is pressed into the chuck 5 that is fixed with the chuck bunching ring, be provided with a chuck and tighten spring 6 between the front end of interior side's lip portions of front end of buffering sleeve 7 and saddle 3, this chuck is tightened spring 6 and is given the elastic force that saddle 3 and chuck mechanism axially retreat.

As shown in figure 11, buffering sleeve 7 is made of a tubular body 7a and its binding spring 7b of portion, and the 7b of spring portion is formed with relative slotted hole 7ba and breach 7bb, and the front end butt of buffering sleeve 7 is limited to the formed shoulder of precentrum 2 internal perisporiums.

As shown in Figure 1, chuck 5 the place aheads are provided with one can front end knockout pipe 8a, and the slider 8 that precentrum 2 openings are outstanding, this slider keep that pen core is unlikely to come off, and the grip part of beam barrel 1 adopts elastomeric material to constitute.

As Figure 14, shown in 16 and 17, the rearward end of beam barrel 1 fix one with the integrally formed tail-hood 10 of the 10a of pen clip portion, the formation of this tail-hood 10 be by a, tubular hold a 10b, with the 10a of pen clip portion that holds a large-diameter portion 10c that a 10b one constitutes, link with large-diameter portion 10c, an and erasing rubber maintaining part 10f.

The described sidewall that holds a 10b is formed with an embedded grooves 10d who stretches to the forward position from large-diameter portion 10c, the open end of this embedded grooves 10d is formed with to holding the importing ditch 10e that a 10b front end enlarges gradually, imports ditch 10e and has as what make tail-hood 10 and beam barrel 1 and lead the chimeric function of rib 1a.As shown in Figure 8, one for the handle hole 1b of the loosening self-supporting tube 10b that prevents internal mechanism along inwall to the restriction rib 1c that protracts.

As shown in figure 13, erasing rubber maintaining part 10f is equipped with the safety head 11 that a top offers a plurality of perforation 11a.Maintaining part 10f at tail-hood 10 offers the pen core through hole 10g (as shown in figure 15) that a filling pen core is used in the centre approximately.

Shown in Figure 14,15,16 and 17, the embedded grooves 10d of tail-hood 10 is stage shape constriction from the open end to its deep, or be skewed constriction gradually, lead the wide slightly narrow chimeric fixed part 10dd of rib 1a and make its penetralia form one than beam barrel 1, after assembling is finished, has the chimeric very firm advantage that can make between the two.

Below with regard to the explanation of the foregoing description assembled condition, shown in Fig. 2,3,4,5,6,7 and 8, at first, chuck is tightened the periphery that spring 6 is set in the chuck linking part 3b of saddle 3 front portions, then will cushion sleeve 7 and install one, and the end that will swim the chuck 5 that is embedded with the chuck bunching ring is pressed into and is fixed in the chuck linking part 3b in its periphery.

Again assembly is led the rib 1a beam barrel 1 of packing into from the rear end of beam barrel 1 with what be embedded in beam barrel 1, subsequently, precentrum 2 is screwed on the beam barrel 1, an end of pressing member 4 is limited to the end of the handle hole 1b of beam barrel 1, tail-hood 10 is pressed into the rear end of fixation in beam barrel 1 again.In this situation, because of the open end of the embedded grooves 10d of tail-hood 10 is provided with introduction part 10e from the wideest constriction gradually, and be provided with beam barrel 1 lead rib 1a with wide or wide slightly chimeric fixed part 10dd, therefore, the holding a 10b and can embed in the beam barrel 1 sleekly of tail-hood 10, and make tail-hood 10 be fixed in the rear end of beam barrel 1 really, subsequently, the pen core through hole 10g of an amount of pen core from tail-hood 10 can be inserted, erasing rubber is installed on the tail-hood 10 again, at last safety head 11 is installed on the tail-hood 10, just finishes its assembling.

Again with regard to the action situation explanation of the side-knock mechanical pencil of the tail-hood of the foregoing description, shown in Fig. 3,4,5,7,8,9,10,11 and 13, at first, when desiring to make pen core when precentrum 2 front ends stretch out, end that can the above-mentioned pressing member 4 of finger presses, so that the inclined plane part 3a of its lower end edge saddle 3 descends, force saddle 3 resisting chuck to tighten the elastic force of spring 6 and advance, in this advances process, because the chuck bunching ring can only end shoulder at the card of precentrum 2 by the butt card, chuck 5 is can break away from restraining of chuck bunching ring and open, and can send pen core then.

The pen core of sending under this state is kept the state that can Gong write by slider 8.In addition, when freeing above-mentioned pressing member 4, saddle 3 is promptly tightened the elastic restoring force of spring 6 by chuck and is retreated, and if this moment is during desire withdrawal pen core, as long as applying light pen core front end just can make in the pen core retraction precentrum.

Aspect pressing operation, be subjected to the restriction of the restriction rib 1c (as shown in Figure 8) that the inwall of beam barrel 1 forms because of pressing member 4, side is pressed control member 4 and is ended by the end card of the side opening 1b of beam barrel 1, when precentrum 2 is removed, though it is mobile that internal mechanism can advance, but pressing lever can not advance, and internal mechanism can not become flexible in pressing operation.

Moreover the fitting portion that the foregoing description is a beam barrel with chimeric rib 1a is the chimeric form of tail-hood with embedded grooves 10d, but that the utility model does not limit the foregoing description is described.That is, if above-mentioned concavo-convex engomphosis relation oppositely is provided with, for example be the fitting portion of beam barrel with embedded grooves 10d, reaching with chimeric rib 1a is the chimeric formation of tail-hood, all ought to be included in the claim of the present utility model.

Again, the foregoing description is customary explanation with the side-knock mechanical pencil, but that this creation is not defined as the foregoing description is described.For example shown in Figure 180, also be located at the slidably control member 4 at beam barrel 1 side opening 1b place by promoting operation one applicable to one, make the operated ballpoint pen of thruster of pen core tube forward-reverse, even also applicable to rear end push type ballpoint pen.

The pen of above-mentioned attached tail-hood has following effect.Tail-hood does not have the problem that comes off and rotate after being installed on beam barrel, and when tail-hood is installed on beam barrel, also there is not the problem of considering the pen clip directionality, again can one by under and easily tail-hood embedding Yu is installed on the beam barrel, its assembling work is good, and the structure of assembling after finishing is also very firm.

Especially, a tool aspect, side operated (side is by reaching thruster), the member in that the anterior sidewall of beam barrel forms reaches the pen clip with tail-hood formation one, after assembling is finished, can be disposed at same plane coaxially, and when the beam barrel of packing into, also can consider the direction of tail-hood, and it is chimeric also very certain, therefore, after assembling is finished, do not have tail-hood to rotate fully and cause the worry that the position generation is staggered between tail-hood and the control member.

On the other hand,, also can utilize the holding section of beam barrel and reach the directionality of saddle and prevent that saddle from rotating by aspect the formula tool in side.And, though just being blocked by an end of the side opening of same tube by control member, side ends, when precentrum was pulled down, pressing lever can not advance mobile with internal mechanism, and internal mechanism also worry of non-loosening in pressing operation.
