に係る。[Detailed description of the invention] The present invention is a tip-knock-type sharp pencil in which centering is achieved by pressing the tip or lead tube at the tip of the pencil against a paper surface (hereinafter referred to as the tip-knock). This invention relates to a device that allows the protrusion length to be easily adjusted according to the user's preference.

多々生じ得る。 A tip-knot type sharp pencil has a slider and a chuck device that are movable back and forth inside the shaft cylinder, and when pressed by the tip notch, they can be pushed back against the force of each elastic member without changing their mutual positional relationship. At that time, the slider is temporarily locked in its retreated position, and when the push-in is released, only the chuck device moves forward to return to its original position relative to the stationary slider, thereby performing centering. In addition, it is possible to configure such a structure that each of the temporarily released locks returns to the original position due to a collision with the slider during the return process. However, with this alone, the centering length is uniformly determined and cannot be adjusted at all. On the other hand, each user has a preferred centering length, and there are many cases where the centering length at the time of purchase does not necessarily match the user's preferred length.

Its steady position is determined by contact with the inner end surface 1a of the shaft cylinder, and the inner surface of the receiving member 6, which supports the rear end of the slider resilient member 7, is provided with a tip notch to press the rear end of the slider resilient member 7. On the inner surface of the receiving member 6 that supports the end,
A locking portion 8 is provided which can be engaged and locked by the locking member 5 attached to the slider 4 when the slider 4 is moved back by the amount that the slider elastic member 7 is compressed by pushing with the tip notch. The retracted position of the slider 4 is determined, and this locking force is not released only by the return force of the slider resilient member 7, but the locking force is not released only by the return force of the slider resilient member 7,
There is no difference between FIG. 1 and FIG. 2 in that it is released when the restoring force is further applied. Although not shown, the locking member 5 may be provided on the shaft cylinder 1 side, and the locking portion 8 may be provided on the slider 4 side.

Centering by the front end notch and centering by the rear end notch can be achieved with the structure shown in FIG. 1, and this point will be briefly explained as follows. Due to the tip notch, the slider 4 that holds the lead with the lead-carrying member 2 and the chuck device 9 that engages the lead move back while maintaining the length l, and the spring seat is pushed by the locking part 15 of the chuck operating tube 11. The body 16 is also a cylindrical relay member 2
2 and retreats away from the front inner end surface 22a of No. 2. When the locking member 5 of the slider 4 is engaged and locked with the locking portion 8, when the pressure from the tip notch is removed,
In the process of the chuck device 9, which is biting the core by the restoring force of the resilient member 21, returning to its original position, the rear end surface of the stationary slider 4 is hit by the push plate 14. Centering is performed by an amount corresponding to the travel length. On the other hand, the slider 4 hit by the push plate 14 is released from its lock and returns to its original position. Apart from centering using the tip notch mentioned above,
When the core storage tube 18 is pushed forward by the rear end notch, the protrusion 19 moves forward away from the rear inner end surface 22b of the cylindrical relay member 22, and the chuck device 9 connected by the sliding friction connection means 17 also moves forward. Centering is performed and the chuck actuating tube 1
1 continues to press forward even after contacting the receiving member 6, the pressing end surface 20 pushes the chuck body 10 to open the chuck mouth, and then when the rear end is stopped, the sliding friction coupling means 17 works. Then, the driver will retreat with the chuck's mouth open, and at the end of the retreat, the chuck's mouth will be closed again.

ることができる。 As is clear from the above description, the present invention includes a spring seat body 16 that can be slidably fitted into the chuck operating tube 11 and locked by the locking portion 15 thereof, and the chuck operating tube 11. The protrusion 19 of the core storage tube 18 is telescopically connected by the sliding friction connection means 17.
A cylindrical relay having front and rear inner end surfaces 22a and 22b so that the spring seat body 16 and the protrusion 19 can come into contact with each other is used. Part 2
2 is screwed into the shaft tube 1 so that it can be set freely in the front-rear direction, so that the shaft tube of the cylindrical relay member 22 can be adjusted freely without impairing either the centering function by the tip notch or the centering function by the rear end notch. 1, the set position of the chuck device 9 can be changed freely, and therefore, the facing distance l between the rear end surface of the slider 4 and the push plate 14 of the chuck actuating tube 11 is variable, and the facing distance l can be changed freely. The one-time centering length determined by can be adjusted as appropriate.
