Embodiment Construction

[0062] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0063] The purpose of the present invention is to provide an interface solution that can be applied to oscillating power tools (such as a multi-function machine) or rotary grinding power tools (such as a sander) and prevent the fit from vibrating due to wear. The installation hole of the working head of the present invention is provided with at least one straight edge, and a protrusion extending toward the center of the installation hole is arranged on the straight edge; the output shaft or the adapter of the power tool is arranged to cooperate with the straight edge of the working head The wall, and the recessed part for accommodating the above-mentioned protruding part is correspondingly provided on the matching wall. When the working head is installed on the output shaft or the adapter, the protrusion on the straight edge of the wo...

Abstract

The invention discloses a work head, and a power tool and adaptors for installing the work head. The work head comprises an installation hole which is connected with an output shaft of the power tool in a matched way; and the installation hole at least comprises a straight line side, wherein a protruded part is extended from the straight line side to the center of the installation hole, so that the risk that the work head is vibrated due to abrasion can be avoided, and great torque can be transferred even the work head runs for long time.

Description

technical field [0001] The invention relates to a working head which can be installed on a power tool, and the working head moves under the driving of the power tool. [0002] The invention also relates to a power tool in which the above-mentioned working head can be used. [0003] The present invention also relates to two kinds of adapters, one is to connect the working head that does not match the output shaft of the above-mentioned power tool to the above-mentioned power tool, and the other is to connect the above-mentioned working head to the power tool that does not match it on the output shaft of the power tool and transmit the torque of the power tool to the work head. Background technique [0004] The multi-function machine is a hand-held oscillating power tool common in the industry. Its working principle is that the output shaft oscillates around its own axis, thereby driving the accessory working head installed at the end of the output shaft to oscillate. Common...
