A power tool includes a main housing, a drive mechanism, a working head, and a connection assembly. The connection assembly includes an input portion connected to the drive mechanism and an output portion connected to an output shaft. The connection assembly rotates the working head about a first axis relative to the main housing. The power tool includes a first transmission path. When the working head rotates about the first axis relative to the main housing, components in the first transmission path are allowed to deform or to be displaced along a direction of the first transmission path.

Power tool

A power tool includes an output assembly and a battery pack. The output assembly is disposed at an end portion of a first handle, the output assembly includes at least two output units spaced apart and used for connecting working accessories, and the output assembly is rotatable about a shift axis to shift an output unit among the at least two output units to a working position or a non-working position. The battery pack is disposed at a bottom of a body, the battery pack includes a standing surface through which the power tool is capable of standing, and when the power tool stands, a projection of a center of gravity of the power tool on the standing surface is in the standing surface.

An electric circular saw includes a housing, a motor including a motor shaft enabled to rotate about a first rotation axis, and a transmission assembly including a first transmission member and a second transmission member. The motor shaft has a first end and a second end oppositely arranged in a longitudinal direction and the first transmission member is mounted to the second end of the motor shaft. In a coordinate system having an origin defined by a point on a center line of the second transmission member, a positive direction of an X axis defined by a forward direction of the electric circular, and a positive direction of a Y axis defined by an upper side of the electric circular saw, the second end of the motor shaft is arranged in a first quadrant of the coordinate system.

Electric circular saw

A power tool includes a main housing in which a drive mechanism is disposed and a working head connected to an end of the main housing and rotating relative to the main housing about a first axis. The working head includes an output shaft and the output shaft is driven by the drive mechanism to rotate about a second axis. The main housing is provided with a window portion and the window portion is configured to display an internal structure of the power tool.

A snow thrower includes a motor, an auger driven by the motor to rotate, a handle device for a user to operate, an auger housing for containing the auger and a frame for connecting the handle device and the auger housing. The auger housing is made of at least two different materials.

Snow thrower

A power tool includes a brushless motor including several windings, a drive circuit for driving the brushless motor, a detection device for detecting the brushless motor so as to obtain a load parameter corresponding to a load of the brushless motor, and a controller for outputting a first control signal to reduce current of the brushless motor in a first slope when the load parameter exceeds a first preset range.

A nail gun includes a housing, a power output assembly, a cylinder, and a firing assembly. At least a part of the power output assembly is disposed in the housing. At least a part of the cylinder is disposed in the housing. The firing assembly includes a firing pin provided with a first drive teeth capable of being driven, the first drive teeth includes a locking tooth provided with a rotating shaft, the rotating shaft is provided with a roller wheel, and the roller wheel is rotatable about a rotating axis.

Nail gun

An electric glue gun includes a housing, a motor supported by the housing, a bracket which extends from the housing for supporting a glue cartridge, a pushing mechanism, supported by the housing and connected to the motor, comprising a drive rod wherein the pushing mechanism is driven by the motor to enable the drive rod to squeeze glue out of the glue cartridge, and a controller configured to control the motor to enable the drive rod to return by a preset distance after the motor stops driving the drive rod forward or after the drive rod reaches a limited position.

A cyclone dust collecting device includes a dust collecting box and a separator. The dust collecting box includes a dust entrance and a cavity formed by extension in a first direction. The dust entrance communicates with a dust exhaust channel of a host machine. The separator includes a dust inlet and a cyclone tube. The dust inlet communicates with the dust entrance. The dust inlet is configured to guide the dust exhaust airflow into the cyclone tube. The cyclone tube extends in a second direction and is at least partially disposed in the dust collecting box. The cyclone tube includes a dust outlet and an air outlet. The dust outlet is located in the cavity and the air outlet communicates with an outside of the dust collecting box. The second direction obliquely intersects the first direction.

Cyclone dust collecting device and grinding device

A power tool includes a housing, a saw blade for cutting a workpiece, a motor for driving the saw blade to rotate about a first axis, a circuit board for controlling the motor, a heat sink for cooling, and a base plate being formed with a flat surface for contacting with the workpiece during cutting. The housing includes a first containing portion being formed with a first container for containing the motor, a second containing portion extended along a direction substantially parallel to the flat surface from one of the two ends of the first containing portion along a direction substantially perpendicular to the first axis. The second containing portion is formed with a second container which is communicated with the first container. The circuit board and the heat sink are disposed in the second container.

A snowthrower includes a motor, an auger driven by the motor to rotate, a handle device for a user to operate, an auger housing for containing the auger and a frame for connecting the handle device and the auger housing. The auger housing is made of at least two different materials.
