Abstract: A pole power tool includes a grip, a brushless electric motor, and a control assembly, where the grip is for a user to hold, the brushless electric motor includes a motor shaft movable around a motor axis, and the control assembly is configured to control operation of the brushless electric motor and includes a circuit board assembly and a circuit element. At least a first plane P exists, the first plane P passes through the circuit board assembly of the control assembly and the motor axis of the brushless electric motor, the first plane P intersects the circuit board assembly along a first line segment AB, and a projection of the first line segment AB on the motor axis at least partially falls on the motor shaft.

Abstract: A multifunctional electric tool has a housing, a motor arranged in the housing, a transmission device driven by the motor, a speed controlling device. At least two output shafts which have different dimensions are to be used with the tool wherein the output shaft is used to control the activation of the speed controlling device. The rotational speed of the electric tool may thus be automatically adjusted to match with the rotational speed of the accessory installed on the output shaft.

Abstract: A power tool includes a housing accommodating a motor therein, a bearing base having a lower surface and an upper end that is connected to the housing, an output shaft that is mounted in the bearing base and protrudes out of the lower surface of the bearing base, a shield that is movably connected with the bearing base, and a locking mechanism for locking the shield relative to the bearing base. The locking mechanism further includes a locking element arranged on the shield and a stop member and the bearing base is formed with a hollow chamber within which the stop member is arranged.

Abstract: To achieve the above-mentioned object, the present invention provides a mixer which comprises a body connecting with a supporting rod, a power system located within the body for driving a mixing paddle to rotate for mixing, and a lifting system for adjusting the location of the body on the supporting rod. The supporting rod comprising a set of teeth distributed on the supporting rod in an axial direction, the lifting system comprising a handle and a gear which is operable with the handle and engaged with the teeth, the body being at a fixed location with respect to the teeth or gear and a lifting system with a lift-locking means having a first member and a second member engaged with each other to limit rotation of the gear.

Abstract: A means for connecting a driving shaft and a mixing paddle of a mixer including a driving shaft, a spindle of the mixing paddle and a clamping means, in which the clamping means comprises a clamping member and a locking member. The clamping member comprises a chamber for receiving the spindle of the mixing paddle, and at least one oblique surface extending along the direction of the spindle. The locking member engages between the oblique surface and the spindle. The clamping means further includes a rotation restricting means for restricting the relative rotation between the spindle and the driving shaft. With this structure, the connecting means is simple, reliable and can be easily operated without auxiliary tools. In fact, an operator may remove and attach the mixing paddle to the driving shaft without auxiliary tools.
