Abstract: A rotary tool mandrel includes a shaft, locking projections, a collar, and a fastener. The shaft extends along a longitudinal axis and includes a distal end. The locking projections protrude radially relative to the longitudinal axis and positioned on opposite sides of the longitudinal axis from one another. Each of the locking projections define a locking projection outer profile that is rectilinear. The collar is coupled to the shaft and includes a pair of coupling projections protruding from a surface of the collar adjacent the distal end of the shaft. The coupling projections are angularly offset from the locking projections with respect to the longitudinal axis. Each of the coupling projections define a coupling projection that is rectilinear. The fastener is coupled to the shaft and movable relative to the shaft along the longitudinal axis, and movement of the fastener causes the locking projections to move toward the coupling projections.

Abstract: A striking tool, comprising a striking head for performing a striking task and a handle connected to the striking head. The handle extends in a direction substantially transverse to a striking direction of the striking head, and comprises a rigid segment having a first rigidity and a flexible segment having a second rigidity sequentially in a direction away from the striking head, the second rigidity being less than the first rigidity. The handle is provided with a gripping part at a position corresponding to an end of the rigid segment that is connected to the flexible segment. The gripping part for a user to grip on the handle thereof is arranged at the end of the rigid segment that is connected to the flexible segment, so as to correspond to one the nodes of vibration formed on the handle during striking.

Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, and a steerable-wheel assembly (SWA). The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a primary drive gear, a primary driven gear, and a secondary driven gear.

Abstract: A rotary tool assembly includes a rotary tool having a body with a working end and a rear end, a motor disposed within the body, and a drive shaft rotatably driven by the motor. A base of the rotary tool assembly includes a battery receptacle configured to receive a battery pack and a stand for supporting the rotary tool when the rotary tool is not in use. The stand includes two arms defining a tool receptacle therebetween in which the rotary tool is supported. A power cord extends between the base and the rotary tool to transfer electric power from the base to the rotary tool to selectively power the motor. The battery pack is received in the battery receptacle for form a foot of the base.

Abstract: A battery pack electrically comprising a temperature terminal and is configured such that when an external device is electrically connected to the battery pack, the device can detect the temperature of the battery pack, and the battery pack is further configured to receive a PWM signal from the external device when in the electrical connection state, and, on the basis of the PWM signal, determine the type and/or operating state of the external device. Also disclosed, a power tool system comprising the battery pack, as well as a communication system for the battery pack and the system. With the battery pack and the power tool system, it is possible to perform both a temperature sampling function and a function of identifying external device information only by a temperature terminal of the battery pack, thus same have the advantages of a simple and compact structure and low cost.
