Problems solved by technology

[0009] Although the above-mentioned interface scheme increases the distance from the opening 94 of the straight saw blade 93 to the axis center of the output shaft 91, the rectangular protrusion 92 of the output shaft 91 is usually smaller in size, and the distance from the engaging section of the opening 94 is correspondingly reduced. Therefore, the final torque provided is still limited, which also cannot meet the needs of customers for high torque transmission applications

[0138] In the above-mentioned embodiment, the first protrusion 107 of the driving part 106 of the output shaft 102 is roughly arched, the second protrusion 108 is roughly triangular, and the shape matching part 115 of the working head 11 has a first protrusion that matches the driving part 106. The installation hole 116 and the second installation hole 117 are in the same shape as the first protrusion 107 and the second protrusion 108 respectively. For those skilled in the art, it will be easy to understand that the cross-sectional shape of the protrusion and the mounting hole is not limited to arch and triangle, and can also be a kind of circle, ellipse, rectangle or trapezoid, and the working head The form-fitting portion 115 can also be set as a single mounting hole, as long as the mounting hole has a first matching portion and a second matching portion respectively matching with the first protrusion 107 and the inner layer protrusion 108 of the driving portion 106 . For de...

Abstract

The invention discloses a power tool and a working head and an adaptor applied to the power tool. The power tool is provided with an output shaft, the working head is mounted on the output shaft and is driven by the output shaft to move, at least one driving portion fittingly connected with the working head extends at the tail end of the output shaft axially, and comprises at least two bumps, the bumps at least include a first bump and a second bump, and the first bumps and the second bumps are formed on different rings adopting the axis of the output shaft as circle centers. Accordingly, high torque can be transmitted, large fit clearance can be shared by the bumps on at leas two layers, and transmission is stable.

Description

technical field [0001] The invention relates to a power tool capable of installing a working head, in particular to an output shaft of the power tool capable of driving the movement of the working head. [0002] The present invention also relates to a working head mountable to the output shaft of the above-mentioned power tool. [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 instal...
