An impact tool having an exchangeable handle structure includes an impact tool main body. A rear-end portion of the impact tool main body forms an engaging portion having two lugs respectively on a top surface and a bottom surface and an annular body on a rear-end surface. Two penetrated portions respectively extend from a top side and a bottom side of the annular body. A left-half part and a right-half part of a front-end portion of a casing cover the lugs and the annular body. A plurality of fixing members respectively passes through the lugs, arm casings formed by the casing, the penetrated portions, and a rear annular casing of the casing. The rear annular casing is connected to a handle having a triggering member. The impact tool main body is detachably engaged with a handle device through the engaging portion.

[Object]

The object of the disclosure is to provide a structuring technique which contributes to the rationalization of dispositioning parts and operability with respect to a striking tool in which usual operation is defined as a striking operation to the downward in a state that the striking tool is downwardly dropped by the own weight of the striking tool.

[Embodiment to Achieve the Object]

A striking tool 100 in which striking operation is done in a state that the striking tool 100 is downwardly dropped by the own weight, having a motor 210 with an output shaft to drive the drive mechanism, a controller 260 to control the motor 210, a functional member 280 to assist the striking operation and a controller case 270 to hold the controller 260, wherein the controller case 270 further holds the functional member 280.

A structuring technique contributes to the rationalization of dispositioning parts and operability with respect to a striking tool wherein usual operation is defined as a striking operation to the downward in a state that the striking tool is downwardly dropped by the own weight of the striking tool. A striking tool is held by a pair of handles by both hands while striking operation takes place when the striking tool drops downwardly by the own weight, a drive mechanism drives an end tool in a first direction and motor, wherein the output shaft of the motor extends in a third direction defined as a thickness direction to cross the first direction and the second direction, and a battery mounting portion is disposed at the side region of the main housing in the second direction, wherein a battery to supply electricity to the motor is mounted to the battery mounting portion.

The present application discloses a pneumatic chipping hammer, and relates to a pneumatic impact tool, which comprises a handle part, the handle part being a hollow member; a main power part, one end of the main power part being connected to the handle part, and principal axes of the handle part and the main power part forming a certain angle; and a chisel part, the chisel part being detachably connected to the other end of the main power part, wherein the direction of mounting the chisel part on the main power part can be changed. According to the pneumatic chipping hammer of the present application, the mounting direction of the chisel part on the main power part is changed by the locking member, and therefore the angle between the principal axes of the handle part and the main power part can be 5-85 degrees, so that a handle is inclined to further achieve different purposes and be suitable for people with different heights.

A power tool having a rotary hammer mechanism has a motor, a driving mechanism, a tool body that houses the motor and the driving mechanism, a handle having a grip part, and a first operation member. The driving mechanism is configured to operate by power of the motor in an action mode that is selected from a plurality of operation modes including a first mode of at least rotationally driving a tool accessory around a driving axis and a second mode of only linearly driving the tool accessory along the driving axis. The grip part extends in a direction crossing the driving axis and is configured to be held by a user. The first operation member is on the tool body and faces the grip part. The first operation member is configured to be manually operated by the user to change the action mode of the driving mechanism.

A power tool fall protection device comprises a sleeve dimensioned to pass over one end of the tool. The sleeve has cheeks projecting from opposite sides of the sleeve to engage a substrate and tabs on the sleeve to inhibit movement of the sleeve along the tool.
