の原因となることが耐久試験結果からわかつた。 As a structure for locking and releasing the slider described above, the present applicant has provided an automatic stop tube between the shaft cylinder and the slider that is biased to tilt around the point of contact with the shaft cylinder side as a fulcrum. , a pressing member located behind the automatic stop tube that straightens the posture of the automatic stop tube by pressing the rear end surface of the automatic stop tube, and enables tilting movement of the automatic stop tube by moving away from the rear end surface. An application was filed for a structure in which the slider is locked against the force of the slider return spring by the frictional resistance at the point where the automatic stop pipe is inclined and contacts the outer surface of the slider (Japanese Patent Application No. 56-90368). This is superior to a slider engagement/disengagement mechanism using an O-ring or the like in that it provides a sharper operation of instantaneous engagement/disengagement. However, when a part of the flange formed on the outer surface of the automatic stop pipe is curved and brought into contact with the shaft cylinder side, and this part is used as a fulcrum for tilting movement, the curved and deformed part becomes flat after long-term use. Durability test results revealed that this could cause malfunction.
本考案は上記した欠点を解消することを目的と

い。 In Figure 1, 1 is the shaft cylinder, 2 is the slider, and 6
is an automatic stop pipe. The slider 2 includes a core tube 3 protruding from a small hole at the tip of the shaft cylinder 1, a core detent 4 exhibiting an appropriate core holding force, and an O-ring 5 fixed to the front outer surface of the slider 2. Automatic stop pipe 6 with a flange 7 formed on the outer peripheral surface of the pipe and a step 8 formed on the inner surface of the pipe
is disposed between the shaft cylinder 1 and the slider 2, urges the automatic stop pipe 6 rearward by a push spring 9 interposed between the stepped portion 1a of the shaft cylinder 1 and the collar 7, and The slider 2
force forward. The above is no different from the example described above.

動止管６は硬質の支点構成部材１２との当接個所
を基点として傾けること、いう迄もない。 The present invention is characterized in that a hard fulcrum member 12 is interposed between the inner surface of the shaft cylinder 1, specifically, the inner surface of the stop ring 11 fixed inside the shaft cylinder 1, and the collar 7 of the automatic stop tube 6. be. Such a hard fulcrum component 12 may be an annular round spring (see Fig. 1), a square spring (see Fig. 5-A) with only a portion overlapped, or a steel material with only a portion of it being curved. There is a ring (see Figure 5-B) or a single steel ball (see Figure 5-C). It goes without saying that the automatic stop pipe 6, which is urged backward by the push spring 9, is tilted with the point of contact with the hard fulcrum member 12 as a base point.

能である。 In the present invention, the posture of the automatic stop tube 6 is corrected straight by pushing the rear end surface of the automatic stop tube 6 toward the rear of the automatic stop tube 6, and conversely, by moving away from the rear end surface, the automatic stop tube 6
This is the same as the above-mentioned example in that the pressing member 13 that enables the tilting movement is provided. The pressing force of the automatic stop tube 6 by the pressing member 13 is applied by a compression spring 14 stretched between the cylindrical body 15 that comes into contact with the rear end of the pressing member 13 and the rear step portion 1b of the shaft tube 1. Further, when the pressing member 13 separates from the automatic stop pipe 6, the inward protruding portion 13a of the pressing member 13 is connected to the chuck operating body so that the pressing member 13 and the chuck operating body 16 retreat together in the backward direction. 16 is slidably fitted into the rear cylindrical portion after the stepped portion 17 formed on the outer surface, and the core is held by a known ball chuck consisting of the chuck actuating body 16, chuck body 23, trochanter 24, and chuck spring 25, and the tip is inserted into the tip. Sometimes this is possible by retracting the entire ball chuck through its core.

照）。 In Figure 2, the tip of the core tube 3 or the core tube 3 in Figure 1 is shown.
This figure shows the state when the tip of the lead protruding from the paper is pressed against the surface of the paper and the tip is notched.
3 is moved backward, and the automatic stop pipe 6 is tilted so that the slider 2
is in contact with the outer surface of the The frictional resistance at this contact point is stronger than the force of the slider return spring 10. Therefore, when the paper is suddenly removed from the paper surface, the ball chuck mechanism and the pressing member 13
moves forward, but since the slider 2 is locked in place, centering is possible. When the pressing member 13 comes into contact with the rear end surface of the slider 2, the slider 2 is corrected to a straight posture, and the slider 2 returns to the state shown in FIG. 1 with the core pulled by the action of the core detent 4. In order to enable more accurate posture correction of the automatic stop tube 6, it is preferable to provide the rear end surface of the automatic stop tube 6 and the front end surface of the pressing member 13 with an inclined surface 26 and a protrusion 27 that engage with each other. (See Figure 4).

きる。 In addition, in order to enable centering by the rear end notch, a predetermined distance is provided between the pressing member 13 that is in contact with the rear end surface of the automatic stop pipe 6 and the front end surface of the chuck actuating body 16, and the core tank is A spring 20 is stretched so as to press the protrusion 19 formed at 18 against the rear end of the cylindrical body 15, and the core tank 18 and chuck actuating body 16 are expandably and contractably connected at a slightly hard fitting point 21. Further, the chuck body 23 may be pushed from the rear with the pushing part 22 of the core tank 18. After the chuck body 23 is advanced by the rear end notch to bring the core into the released state, the annular elastic body 5 is frictionally engaged with the inner surface of the automatic stop tube 6 by retracting the slider 2 deeply by the tip notch (the third (see figure), when carrying
Unexpected centering due to back and forth movement of the slider 2 can be prevented.
