めに、規定寸法が狂いやすい欠点があつた。 In most known sharp pencils, the barrel and tip are fixed to a guide that supports the lead tank and chuck mechanism, so the chuck mechanism may be affected by dimensional errors in the barrel, the amount of screwing, etc. The distance between the fastening ring and the step in the tip metal that it comes into contact with changes, and this dimension determines the accuracy of core feeding, which has the disadvantage that the specified dimensions are likely to deviate.

定寸法に狂いが生じないようにしたものである。 The present invention has improved such drawbacks and has various other features.A connecting part is formed at the base end of the tip, and a core tank, chuck mechanism, etc. are installed inside the connecting part. Fit the guide tube to be supported,
By fitting the shaft cylinder on the outside, the distance between the tightening ring of the chuck mechanism and the step inside the tip is always kept constant regardless of the dimensions of the shaft cylinder, the mounting condition, etc., and deviations from the specified dimensions are avoided. This was done to prevent this from happening.

取付けやすい。 In the one shown in the figure, the tip 1 has a lead insertion hole 2, a lead gripping piece 3, and a stepped part 4 on which a fastening ring of a chuck mechanism (to be described later) comes into contact, and a cylindrical connecting part 5 at the base end. is formed. A female thread 6 and a male thread 7 are formed on the inside and outside of the connecting portion, respectively. The lead tank 8 that stores the lead has a chuck 10.
The chuck 10 has a fastening ring 11 at its tip, and the tip is inserted into a guide tube 13.
A spring 9 is provided between the flange portion 13a provided at the base end of the guide tube and the core tank 8 to constitute a chuck mechanism. The guide tube has a cylindrical portion 13b provided with a male thread 12 on the outer periphery below the flange portion, and is provided at the base end of the guide tube with the fastening ring 11 housed in the cylindrical portion 13b. flange portion 13a
The male screw is screwed into the female thread 6 inside the connecting portion of the tip until it touches the base end of the connecting portion of the tip, and the guide tube is engaged with the connecting portion. On the other hand, a female thread 15 is formed at the tip of the shaft tube 14 whose inner diameter is larger than the diameter of the flange of the guide tube, and the female thread is connected to the tip until the tip touches the outer circumferential step of the tip. Screw it onto the outside of the section to fit it into place. In addition,
If a non-slip member 16 such as an uneven strip is formed on the circumferential surface of the upper portion of the guide tube as shown in the figure, it will be easier to attach the guide tube.

きる。 With the above configuration, the distance between the lower end of the fastening ring 11 in the figure and the stepped portion 4 of the tip can be made constant by securely attaching the guide tube to the tip. Therefore, when the rear end of the core tank is knocked and the chuck mechanism is advanced to feed the core, the tightening ring moves forward by a specified amount regardless of the dimensions and mounting condition of the shaft cylinder, so the core feed is always the specified amount. can do.

ができると共に組み立てがきわめて容易である。 The present invention is constructed as described above, and the guide tube supporting the chuck and the fastening ring is provided at the base end of the guide tube, with the fastening ring housed in the cylindrical part provided at the tip of the guide tube. It is only necessary to fit and engage the flange portion inside the connecting portion of the tip until it touches the base end of the connecting portion of the tip, and thereby the distance between the fastening ring and the stepped portion of the tip is equal to that between the guide tube and the tip. Since the shaft cylinder is correctly determined based only on the metal, and the inner diameter is larger than the diameter of the flange portion, and is fitted onto the outside of the connecting portion of the tip, the shaft can be fixed after combining the chuck mechanism and the tip. It can be easily assembled by inserting it into the cylinder, and even when doing so, the distance between the tightening ring and the stepped portion does not change at all times. Also, attach the chuck mechanism to the tip as shown above,
Since it is separated from the shaft cylinder, it can be incorporated into various shaft cylinders and is extremely easy to assemble.
