  • Publication number: 20230349538
    Abstract: A standing light includes a light assembly, a support rod assembly, and a housing assembly. The support rod assembly is configured to support the light assembly. The housing assembly or the support rod assembly is formed with a power access interface for being connected to a power supply. The standing light further includes a mounting assembly configured to detachably install the light assembly to the support rod assembly. When the light assembly is installed to the support rod assembly, the light assembly is capable of being powered by the power supply connected to the power access interface. The light assembly is further formed with a power supply access interface for accessing power, and when the light assembly is detached from the support rod assembly, the light assembly is capable of being detachably connected to a battery pack through the power supply access interface.

  • Publication number: 20230051358
    Abstract: A power tool includes a casing, a cutting unit, a transmission device, and a toggle switch. The casing includes a support portion. The cutting unit is used for cutting a target object and moving between a first position and a second position relative to the support portion. The toggle switch includes at least a third position and a fourth position. When the toggle switch is at the third position, the cutting unit performs a first motion: the cutting unit moves from the second position to the first position. When the toggle switch is at the fourth position, the cutting unit performs a second motion: the cutting unit moves from the first position to the second position. A speed at which the cutting unit performs the second motion is greater than a speed at which the cutting unit performs the first motion.

  • Publication number: 20220057079
    Abstract: A reciprocating saw includes a casing, a clamping mechanism, a bracket, a first light-emitting piece, and a second light-emitting piece. The casing extends in a front-and-rear direction and forms an accommodation space. The clamping mechanism is disposed at least partially in the accommodation space and configured to clamp an operation accessory. The bracket is disposed at least partially on a front side of the clamping mechanism. The first light-emitting piece and the second light-emitting piece are disposed on a front side of the casing. The first light-emitting piece fits with the bracket and the operation accessory so that a cutting indicator line distributed in an extension direction of the operation accessory is formed. The second light-emitting piece fits with the bracket so that a cutting indicator region perpendicular to the cutting indicator line and extending in an up-and-down direction is formed.
