Embodiment Construction

[0044] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0045] The multi-purpose rotary impact tool of the present invention can be operated in an impact mode in which the impact mechanism 6 including the hammer 61 and anvil 91 is used, and in a drill driver mode in which the output shaft 9 rotates without causing impact on the impact Any impact operation of mechanism 6. The impact mode and the drill driver mode can be switched by a switching unit that is externally operated by using the switching operation unit 14 .

[0046] Such as figure 1 As shown in , the multipurpose rotary impact tool according to the first embodiment of the present invention is a portable rotary impact tool driven by a built-in power supply (not shown). In a rotary impact tool, the output power of the motor 13 is transferred to the drive shaft 8 through a multi-stage reduction mechanism. The impact output power is applied from the dri...

Abstract

A rotary impact tool includes a drive power source for producing rotational power, a drive shaft driven by the rotational power supplied from the drive power source, an output shaft operatively connected to the drive shaft for receiving the rotational power, an impact mechanism operatively couplable with the drive shaft. The rotary impact tool further includes a changeover unit for changing over an impact mode in which the impact mechanism is operated and a drill driver mode in which the rotational power produced by the drive power source is transferred to the output shaft without operating the impact mechanism and a multi-stage speed reduction mechanism for transferring the rotational power produced by the drive power source to the output shaft through the drive shaft at variable speeds in at least three speed modes including a low speed mode, a middle speed mode and a high speed mode.

Description

technical field [0001] The present invention relates to a rotary impact tool, and more particularly, to a rotary impact tool capable of switching between an impact mode and a drill driver mode. Background of the invention [0002] Conventionally, there is known a multipurpose rotary impact tool capable of switching between an impact mode in which a bolt, nut or screw is tightened by an impact mechanism having a hammer and an anvil, and a drill driver mode in which drilling is performed Tasks such as pilot hole forming and screw tightening simultaneously limit the impact action of the impact mechanism. [0003] When performing drilling operations or other operations in the drill driver mode, it is desirable to reduce the operating speed to a value less than that available in the percussion mode in order to prevent cracks or other failures in the drill bit. In addition to inhibiting or releasing the impact mechanism when switching the respective modes, the reduction ratio cha...
