Dust collecting device and impact tool

摘要

In a dust collection device that collects dust particles that an impact tool generates, disclosed is a feature that can accommodate the lengths of tool bits that are mounted to the impact tool when a machining operation is executed by exchanging tool bits of different lengths. The dust collection device collects dust that the impact tool generates and is attached to said impact tool that, in the lengthwise direction, linearly operates the tool bit mounted to the end region of a tool body. The dust collection device has a dust intake port that sucks dust, and said dust intake port can be repositioned in the lengthwise direction of the tool bit in accordance with the length in the lengthwise direction of said tool bit.

主权项

1. A dust collecting device that is attached to an impact tool and collects dust generated by the impact tool in which a tool bit coupled to a front end region of a tool body is caused to rectilinearly move in an axial direction of the tool bit, comprising:
a dust suction port through which dust is sucked up and which can be adjusted in position in the axial direction of the tool bit according to a length of the tool bit in the axial direction, a dust collecting part having the dust suction port at its front end, a dust transfer part which is connected to the dust collecting part in order to transfer dust downstream from the dust suction port, the dust transfer part comprising a dust collecting hose which extends in the axial direction of the toll bit and has a bellow-like part formed at least in part of the dust collecting hose, and a hose holding part which can be mounted to the tool body and engaged with the bellow-like part so as to hold the dust collecting hose on the tool body, wherein the position of the dust suction part in the axial direction of the tool bit can be adjusted by changing as engagement position of the bellow-like part in an axial direction with respect to the hose holding part.
