ができる。Effects Therefore, with the above configuration of the present invention, the piston from which the pin needs to be extracted is positioned between the flexible belt and the pin pressing part provided on the threaded rod, and the flexible belt that is wound around the piston's outer circumference is free. Fix the end of the belt to a locking member by adjusting the length of the belt, place the pin release opening of the flexible belt facing the direction in which the pin comes out, and place the pin pressing part of the threaded rod against one end of the pin. Rotate the control part of the stick. When the threaded rod is rotated, the pin pressing portion of the threaded rod pushes the pin toward the opening of the flexible belt, allowing the pin to be extracted.
実施例
以下に本考案を図面の実施例に基づいて説明す
る。Embodiments The present invention will be explained below based on embodiments shown in the drawings.
図面は一実施例としての内燃機関用ピストンピ

中心部に螺合しており、台４の一側に平織りベル
ト等の丈夫な可撓ベルト５の固定部を有し、ベル
トの一端を直接固着し、他側にはベルト長さ調節
自在な係止部材６をねじ７で固定している。 The drawing shows a piston pin extraction tool for an internal combustion engine as an example, in which a threaded rod 1 is a T-shaped member with a handle portion 2 as an operating portion formed at one end thereof, and a small diameter portion formed at the other end. Pin pressing part 3
It is said that Further, this threaded rod 1 is screwed into the approximate center of a plate-shaped base 4, and has a fixed part on one side of the base 4 for a strong flexible belt 5 such as a plain weave belt, and one end of the belt is directly connected to the base 4. A locking member 6 whose belt length can be adjusted is fixed to the other side with a screw 7.
ベルト５は図示の如く、ねじ棒１のピン押圧部
３の対向位置に開口８を形成している。この開口

なり、ベルトを折りたたんでコンパクトに収納す
ることができる。 As shown in the figure, the belt 5 has an opening 8 formed at a position facing the pin pressing portion 3 of the threaded rod 1. The length of this opening in the longitudinal direction of the belt is set so that it can be used to correspond to various piston sizes.For example, the same tool can be used for each piston size with an outer diameter of 25 to 60 mm. Unlike conventional steel belts, the belt can be folded and stored compactly.
本実施例のピン抜き取り工具は、ピストンをそ

らに好適である。 The pin extraction tool of this embodiment has a pin pressing portion 3 having both ends of the piston pin having a threaded rod 1.
and the opening 8 of the belt 5, and the free end of the belt 5 is passed through the locking member 6 and locked, and when the handle part 2 of the threaded rod 1 is rotated in this state, the pin is pressed. The section 3 pushes the piston pin through the opening 8 in the belt 5. It is more preferable if a bush corresponding to the outer diameter of the piston pin is fitted into the pin pressing portion 3.
