Problems solved by technology

However, a disadvantage of this form of device is that, in the case of drill chucks used to operate the transmission of a reciprocating saw, a lot of energy is expended in driving a drill chuck first and then driving the saw by the chuck. device conversion device
Or, where such tools incorporate interchangeable drilling heads, the various functions are somewhat limited by varying the drilling speed

Embodiment Construction

[0020] see figure 1 , generally indicated by the reference numeral (2), includes a body portion (4) conventionally formed from two clamshell halves (6, 8). The two clamshell halves fit together to enclose the internals of the power tool as described below.

[0021] The main body portion (4) defines a generally D-shaped body and the rear portion (10) of the body defines a conventional pistol grip gripped by the user. Projecting inwardly from the rear portion (10) is an actuation trigger (12) which can be operated by the user's index finger in the normal manner of operation of the power tool mechanism. This pistol grip structure is a conventional structure, so the part related to this embodiment will not be further described. The front portion (14) of the D-shaped body can be used for dual purposes, it can provide protection when the user's hand grasps the pistol grip portion (10), and can also be used to accommodate two batteries (26) (see Figure 5 ) to provide power to too...

Abstract

A power tool system includes a tool body in which an activation switch (12) controls a motor (20). A plurality of interchangeable tool heads (50) are able to be accepted by the power tool in order to provide a dedicated tool. A releaseable lock-off mechanism (90) is incorporated in the tool body which restrains actuation of the activation switch (12) when none of the tool heads (50) is present.

Description

technical field [0001] The present invention relates to a power tool, and more particularly, to a power tool having a conventional body portion and incorporating a variety of interchangeable tool holders. Background technique [0002] Due to the tremendous growth in the field of power tools and the increased demand in the do-it-yourself (DIY) market, the number of different types of power tools available to users has grown dramatically over the past 10 years. Especially the most reluctant of DIY enthusiasts will own a power drill and jigsaw, while the more enthusiastic among them will also need electric sanders, electric files, electric punching cutters and other special-purpose electric tools. tool. Although this vast array of power tools is often found useful, having such a large number of tools is expensive and requires considerable storage space. Furthermore, using a dedicated tool for each job often results in significant under-utilization of such tools (often all of ...
