A power tool (12) is provided and may include a motor (18), an output shaft (25), a neck portion (32), and a collar portion (34). The output shaft (25) may be driven by the motor (18). The neck portion (32) may be configured to receive a removable attachment accessory (14). The neck portion (32) may define a first diameter and may include a plurality of indexing features (38). The collar portion (34) may be supported by the neck portion (32). The collar portion (34) may include an outer circumferential surface defining a second diameter that is greater than the first diameter. The outer circumferential surface may include at least one recess (42).

A crimping head for use with an impact wrench to crimp fittings onto a structure carrying the fitting, that includes a universal adaptor having a head, and a socket positioned in the head sized and shaped to receive a standard anvil of an impact wrench without further connection between the impact wrench and the crimping head. A locking assembly is provided for cooperating with the universal adaptor head for locking the anvil into the socket, and a transmission is attached to the universal adaptor for being driven by the universal adaptor and for converting rotational movement of the anvil into selective rearward and forward movement. A jaw assembly is attached to the transmission and adapted to close into a crimping position and open into a release position responsive to the rearward and forward movement of the transmission.

A combined electric tool comprises at least one main body and at least one working part which may be separated or connected, wherein a separable and connectable transmission device is arranged therebetween, the main body is provided therein with an electric motor and a control circuit, the control circuit comprises a signal recognition module comprising a microcontroller, the working part is provided therein with an identification module, and the signal recognition module and the identification module are electrically connected or in wireless communication, such that the microcontroller can recognise the working part. The combined electric tool can recognise different working parts, and is safe and efficient in operation because different control methods are adopted against different working parts, and at the same time, the electric motor in the main body is in common use and thus the hardware cost is remarkably reduced. Also disclosed is a control method for the combined electric tool.

Positive feed tools that include gear heads configured to be driven by a motor. The gear heads further include a pneumatic manifold that provides for access to input/output signals to add on additional components that include additional air logic functionality. The gear head includes first and second interface positions. Each interface is configured to receive either the motor for powering the gear head or an add-on component to provide additional functionality to the tool.

Handheld power tools may be manufactured for one type of use or may be multi-purpose in that different tools may be attached to them, each driven by the same motor. The point of connection between the handle and the tool is potentially weak. This connection is strengthened by providing a handheld power tool (10) comprising a handle (30), the handle including a motor (45), a drive shaft (100), and an attachment mechanism arranged for attaching various interchangeable tools (20) onto the handle for being driven by said motor, the drive shaft including, at one longitudinal end, a first rotational connection means (120) for engagement with a second rotational connection means (130) provided on each of the various tools, wherein the power tool is configured for the sliding, of the various tools onto the handle, in a direction substantially non-parallel to the rotational axis of the first connection means.
