Abstract

Hand-held power tools are manufactured for one purpose, or for multiple purposes, as different tools are connected to them and driven by the same motor. There is a potential defect in the connection point between the handle and the tool. This connection point has been enhanced by providing a hand-held power tool (10) comprising a handle (30) including a motor (45), a drive shaft (100) and a connection mechanism for connecting various Interchangeable tool (20) - connected to the handle so that it can be driven by the motor, the drive shaft includes, at one end in the length direction, a first rotary connection (120) for connecting with a The second rotary connection device (130) provided on each different tool is connected, wherein the power tool is configured such that various tools can slide the upper handle in a direction not substantially parallel to the rotation axis of the first connection device.

Description

technical field [0001] The present invention relates to a hand-held power tool, in particular, but not exclusively, to a portable hand-held power tool. Background technique [0002] According to known multipurpose power tools, a desired utility device can be connected and changed as required. For example, AU2011213853A1 discloses a device whereby any of the devices described below can be connected to a main body; impact screwdrivers, drills, hammers, sanders, saws and lamps. Each tool is connected to the main body by being arranged on the driving device in a direction parallel to the rotation axis of the driving device. The tool is then rotated relative to the body portion, thereby locking in this position. When each tool is attached, it is attached by interlocking tabs and slots located around the inner perimeter of the tool. Due to their nature, these interconnections are relatively inefficient in keeping a tool connected to a body portion if a lateral force is applied ...
