Problems solved by technology

While this has been achieved in some power tools with a second switch that is pressed in addition to the trigger switch in order to operate the tool, this solution requires a switch between the second switch and the trigger switch. hardwired
However, this is difficult for a power tool with a removable or removable second handle because a wired connection between the second handle and the trigger switch would require exposed wires, the second handle and the trigger switch to bend and move with the handle. Movable electrical contacts between tool bodies, or some other complex arrangement

Embodiment Construction

[0016] Referring now to the accompanying drawings, in particular figure 1 , shows the power tool 10 . The tool 10 shown in the drawings is a torque driver 10 , although a variety of power tools can be used with the present invention herein. As shown, the tool 10 has a tool housing 12 which encloses an electric motor 14 . Although electricity can be provided by wires, the figure 1 The tool 10 shown in is a cordless tool 10 having a battery 16 that provides power to operate an electric motor 14 and an on-board control system 18 . Tool housing 12 also includes a first handle 20 that an operator grasps when using tool 10 , eg, to pick up tool 10 , move tool 10 , and position it. The first handle 20 also includes a first switch 22 , such as a conventional trigger switch 22 , that turns the electric motor 14 on and off to generate torque at an output drive 24 .

[0017] The power tool 10 also has a second handle 26 connected to the tool housing 12 . Typically, when using the to...

Abstract

An electric tool is provided with a second switch that is actuated in order for the tool to be used. The second switch is on a second handle that is grasped by the operator with a different hand thanthe hand that actuates the main trigger switch. Communication between the second switch and the tool occurs with a wireless signal indicating that the second switch has been actuated.

Description

technical field [0001] The present invention generally relates to power tools and devices having two switches that are actuated to operate the tool. Background technique [0002] There are many types of power tools used in assembly operations. In some cases, it is desirable for a power tool to have two handles for operating the tool. For example, the tool may have a handle with a trigger switch for the operator to turn the tool on and off. In situations where significant torque output is likely from the tool, it may be desirable to have a second handle that the operator can grasp with his other hand to resist the torque output. In high torque applications and in industrial settings, the operator may be expected to keep both hands on the tool before the tool is operated. While this has been achieved in some power tools with a second switch that is pressed in addition to the trigger switch in order to operate the tool, this solution requires a switch between the second swit...
