摘要： The disclosure provides a handheld power tool, which at least includes a housing assembly, a handle assembly and a switch assembly. The switch assembly includes a button assembly and a push-pull assembly. When the push-pull assembly is configured to complete at least two actions, the button assembly is unlocked, the first action is to slide back and forth along the handle assembly, and the second action is to slide back and forth obliquely along the handle assembly. With the handheld power tool of the disclosure, a trigger switch can be unlocked by a palm, so as to improve a problem of poor comfort during use caused by unlocking the trigger switch by a thumb.

摘要： A power tool includes a housing, a driving device, a cutting device and an oil storage device. The driving device, the cutting device and the oil storage device are all mounted in the housing. The driving device may drive the cutting device to work, and the oil storage device provides lubricating oil to the cutting device. The oil storage device includes an oil reservoir and an oil pump, the oil reservoir is connected with the oil pump through a first oil pipe, and a filtering structure is arranged between the first oil pipe and the oil reservoir to filter the lubricating oil entering the oil pump from the oil reservoir. The oil reservoir provides lubricating oil to the cutting device through the oil pump. The oil storage device of the disclosure may effectively improve a clogging problem of the oil pump and improve a duration life of the power tool.

摘要： A handheld power tool (1) comprising a tool (8), a motor (2) configured to power the tool (8), an actuator (3), a control arrangement (21), and a connector portion (5) configured to receive a pole connector portion (15) of a pole extension unit (10) for increasing the reach of the power tool (1). The power tool (1) comprises a safety switch (9) configured to switch from a first state to a second state when a pole connector portion (15) is attached to the connector portion (5) of the power tool (1). The control arrangement (21) is configured to prevent a control of operation of the motor (2) based on input from the actuator (3) when the safety switch (9) is in the second state. The present disclosure further relates to a pole extension unit (10) and power tool assembly (20) comprising a handheld power tool (1), and a pole extension unit (10) for increasing the reach of the power tool (1).
