Electric power tool

Abstract

An electric power tool capable of selecting an operation mode with good operability without risk of erroneous operation even though there are many operation modes. The gear box (12) in the housing respectively has: the clutch switching groove (65) engaged with the operation protrusion (62) of the clutch switching handle (57); ) of the notch (81) of the guide body (82) of the stepped pin (83) engaged; the vibration switching groove (101) engaged with the operation protrusion (98) of the vibration switching handle (93), and the The integrated rotary position of the switching plate (31) can change the combined switching box (64) of the sliding position of each switching member, and use the switching button (30) to rotate and operate the switching plate (31) and the switching box (64) from the outside of the housing, so that Only the operation of one switch button (30) can select all action modes of drilling mode, impact mode, vibration drilling mode and clutch mode.

Description

[0001] This application is a divisional application of an application with an application date of October 21, 2005, an application number of 200510114289.0, and an invention title of "electric tools". Technical field [0002] The present invention relates to an electric tool that can give intermittent blows or vibrations in the axial direction to an output shaft protruding from the front of a housing by selecting an action mode. Background technique [0003] As an electric tool, for example, an impact tool described in Patent Document 1 and the like are known. Here, the rotation of the output shaft of the motor is transmitted to the drive shaft in the housing via the planetary gear reduction mechanism. On the drive shaft, a hammer loaded forward by a coil spring is mounted on the outside of the ball. The arm of the anvil (output shaft) protruding from the front of the main body case is engaged to transmit the rotation of the drive shaft to the anvil via the hammer. When the load o...

Problems solved by technology

[0012] When there are many selectable action modes like this, it is necessary to separately operate the impact switching member for switching the impact mode and the drilling mode, the clutch switching member and the vibration switching member for switching the drilling mode to the clutch mode or the vibration drilling mode, thereby Poor operability and prone to misuse

[0013] On the other hand, in the above-mentioned vibratory drilling, since the loading device for loading the main shaft to the forward position and the loading device for loading the chuck sleeve are respectively provided, the number of parts increases, the structure is complicated, and the time for assembly is also increased. closely related to cost increase
