摘要： A hammer drill (1) includes a lock plate (35) forward of a boss sleeve (13) and a swash bearing (14) which cooperates with the boss sleeve to convert the rotation of an intermediate shaft (5) on which the boss sleeve is mounted. The lock plate is mounted on the boss sleeve and selectively engages claws (23) of the boss sleeve (13) in a manner that permits its integral rotation with and axial slide with respect to the boss sleeve. The lock plate is additionally biased in the forward direction by a coil spring (38) so that when a clutch (19) is shifted forward in a drill mode, the lock plate also moves forward into engagement with a stopper (39) secured to an inner housing (4), preventing inadvertent rotation of the boss sleeve.

摘要： An impact tool includes a reaction force transmitting member, a first elastic member that biases the transmitting member forward, and a second elastic member that is pushed by the transmitting member and compressively deforms when the transmitting member moves rearward by receiving a striking reaction force caused when a tool bit strikes a workpiece, thereby cushioning the force. When the tool bit is pressed against the workpiece, the transmitting member is pushed by the tool bit and compresses the first elastic member, and comes in contact with the second elastic member in an uncompressed state, so that the transmitting member is placed in a predetermined working position in the longitudinal direction. When the transmitting member receives the striking reaction force in the working position, the transmitting member moves rearward in the axial direction of the tool bit and compressively deforms the second elastic member, thereby cushioning the striking reaction force.

摘要： An impact tool includes a vibration-proofing cushioning material connecting a tool body and a handle. The tool further includes a motor-driving manual operating member disposed on the handle, an operation mode switching member disposed on the tool body, and a movable member. When the switching member is switched to first mode in which the tool bit is continuously driven, the movable member moves the manual operating member from an off position and locks it in an on position. When the switching member is switched to second mode in which the tool bit is arbitrarily driven, the movable member releases the lock of the manual operating member. A vibration-proofing elastic member is disposed in the vibration transmitting path and prevents vibration caused in the tool body from being transmitted to the handle in the state in which the manual operating member is locked in the on position by the movable member.

摘要： Accordingly, it is an object of the present invention to provide an effective technique to improve ease of operation of the power impact tool. The representative power impact tool according to the present invention includes a tool body, a tool bit, a motor, first and second switches and a mode changing mechanism. The tool bit performs a striking movement. The motor is driven only when both of the switches are turned on. The first switch is urged from the on position side to the off position side and normally held in the off position. The second switch is turned between the on position and the off position and held in one of the on and off positions unless operated to be turned to the opposite position. The mode changing mechanism switches between hammer operation modes of the tool bit. According to the first hammer mode, the user is allowed to actuate the first switch while the second switch is locked in the on position. Further, according to the second hammer mode, the first switch is locked in the on position while the user is allowed to actuate the second switch. According to the invention, when the power impact tool is operated in the second hammer mode, the first switch is locked in the on-position while the user is allowed to actuate the second switch such like a toggle switch to drive the motor. Therefore, the user is not required to keep the first switch in the on-position by hand in the second hammer mode. As a result, ease of operation of the power impact tool is enhanced compared with the known art.
摘要翻译：因此，本发明的目的是提供一种有效的技术来改善动力冲击工具的易操作性。根据本发明的代表性动力冲击工具包括工具主体，工具钻头，马达，第一和第二开关以及模式改变机构。工具位执行醒目的运动。只有当两个开关都打开时，电机才被驱动。第一开关从位置侧被推压到关闭位置侧并且通常保持在关闭位置。第二开关在打开位置和关闭位置之间转动并且保持在打开和关闭位置中的一个位置，除非操作以转动到相对位置。模式切换机构切换工具钻头的锤击操作模式。根据第一锤击模式，允许用户致动第一开关，同时第二开关锁定在接通位置。此外，根据第二锤击模式，第一开关被锁定在接通位置，同时允许使用者致动第二开关。根据本发明，当动力冲击工具以第二锤模式操作时，第一开关被锁定在就位，同时使用者能够像拨动开关一样致动第二开关来驱动马达。因此，用户不需要以第二锤模式手动将第一开关保持在就位。结果，与现有技术相比，动力冲击工具的易操作性得到提高。
