  • Patent number: 12648525
    Abstract: A hedge trimmer includes a blade assembly, a power assembly, a battery pack, a connecting rod and a handle assembly. A first end of the connecting rod is fixedly connected with the power assembly and a second end of the connecting rod is connected with a battery pack cavity. The battery pack is mounted in the battery pack cavity, and the power assembly accounts for less than 46% of a weight of the hedge trimmer. The disclosure reduces a weight of the power assembly at a front end through placing the battery pack behind, and a hedge trimmer may not turn its head, which shortens an overall length requirement of the hedge trimmer. Therefore, a weight of the hedge trimmer is reduced, and a structure of the hedge trimmer is compact.

  • Publication number: 20240100729
    Abstract: 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.
