Embodiment Construction

[0035] Below, refer to Figure 1-11 , representative embodiments of the present invention will be described. This embodiment will be described using a hand-held hammer drill as an example of an impact tool. Such as figure 1 As shown, the hammer drill 100 is made by making the hammer head 119 installed in the top end region of the main body 101 in the long axis direction ( figure 1 It is a hand-held impact tool that makes an impact action on the left and right directions in the center and rotates the hammer head 119 around its axis (long axis direction) to perform stripping or drilling operations on the workpiece (such as concrete). The hammer head 119 is an implementation structure example corresponding to the "tip tool" in the present invention.

[0036] [The overall structure of the hammer drill]

[0037] Such as figure 1 and figure 2 As shown, the hammer drill 100 is mainly composed of a main body portion 101 and a handle portion 109 constituting the outer contour of...

Abstract

A power tool includes a motor, a driving mechanism, a body housing, a handle, and a rear position defining member. The driving mechanism is driven by the motor and configured to drive a tool bit in a longitudinal direction. The body housing houses the motor and the driving mechanism. The handle is connected to the body housing so as to be allowed to move with respect to the body housing between a front position and a rear position in the longitudinal direction, while being biased by a biasing member in the longitudinal direction. The handle includes a handle base and a handle cover. The rear position defining member extends from the body housing to a position between the handle base and the handle cover in the longitudinal direction and is configured to define a rear position of the handle.

Description

technical field [0001] The invention relates to a working tool for processing a workpiece. Background technique [0002] International Publication No. 2007 / 068535 describes a rotary hammer having a drive unit and a transmission unit. The rotary electric hammer has a casing unit for accommodating a transmission unit and a casing unit for accommodating a drive unit. The casing unit for accommodating the driving unit is integrated with the main handle. In addition, the housing unit housing the transmission unit and the housing unit housing the drive unit can move relative to each other. The housing unit integrated with the main handle provided in the rear end area of ​​the rotary hammer extends to the top end area of ​​the rotary hammer where the auxiliary handle is mounted. [0003] [Patent Document 1] International Publication No. 2007 / 068535 [0004] In the rotary hammer described above, the relative movement between the housing units is guided by a plurality of guide me...
