| 摘要 |
A bellows insert (25) is shown, mountable inside a bellows for a vacuum powered tool and, in the mounted position, effective to locally limit the capacity of the bellows of compression in its longitudinal direction caused by a negative pressure introduced into the bellows. The bellows insert includes an engagement part (26) that has a shape complementary to the inside of the bellows and that, in the mounted position of the bellows insert, fills up some or all of the pleats of the bellows, within a limited area of the circumference of the bellows. |

1. Bellows insert (25) mountable inside a bellows for a vacuum powered tool and, in the mounted position, effective to locally limit the capacity of the bellows of compression in its longitudinal direction caused by a negative pressure introduced into the bellows, which bellows insert comprises an engagement part (26) that has a shape complementary to the inside of the bellows and that, in the mounted position of the bellows insert, fills up some or all of the pleats of the bellows, within a limited area of the circumference of the bellows, wherein the engagement part (26) extends between a first and a second end, characterized in that the engagement part (26), in said first end, has a fixing member (29) for rotational fixation of the bellows insert in relation to the bellows, said fixing member comprising a pin (29) that is formed with a through channel (28) and, in the mounted position of the bellows insert, formed to be rotationally fixedly received in a vacuum connection implement engaging the bellows. |
