A gapless spindle locking device of an improved structure includes an output shaft, a power output disk, a stop ring and lock pins. The power output disk is connected to a driving device. A polyhedral shaft is disposed at an end of the output shaft and the polyhedral shaft has a lock section and a power transmission section. Lock planes matched with the lock pins are disposed on the lock section in a circumferential direction. A driving structure for transmitting power is disposed on the power output disk. A driven structure for transmitting power is disposed on the power transmission section, and the driving structure is matched with the driven structure. Spacing pillars protruding upwards are disposed on a surface of the power output disk in the circumferential direction, and a damping block is disposed between every two adjacent spacing pillars.

An electric vibration driver drill as one example of an electric power tool includes the gear housing, the vibration mechanism and the clutch mechanism each located inside the gear housing, the mode switching ring (vibration switching ring) configured to operate the vibration mechanism and rotatably held to the gear housing, the clutch ring (clutch switching ring) configured to operate the clutch mechanism and rotatably held to the housing, and the respective balls located between the mode switching ring and the clutch ring.

A portable power tool has a drive unit for rotationally driving a tool receptacle about an axis of rotation, the drive unit having at least one drive motor and a shiftable transmission, which is arranged in a transmission housing with an at least partially sleeve-like clutch housing and a transmission cover fastened thereto. The tool includes a shifting element for shifting the shiftable transmission between at least two different gears, and a locking sleeve for locking the shifting element in at least a first and a second shifting position is arranged in the clutch housing. The shiftable transmission forms, at least in the first shifting position, a cross-sectional plane perpendicular to the axis of rotation in which the locking sleeve is arranged at least regionally between the transmission cover and the shifting element and the shifting element is arranged at least regionally between the locking sleeve and the clutch housing.

A tool with a transmission assembly having a reduction gearset and a speed selector. The speed selector has a member, an actuator and a shifter assembly. The member is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator includes a pivoting yoke and a follower that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly has a selector switch, a switch fork, and a pair of springs. The selector switch is slidable between a first switch position and a second switch position. The switch fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the switch fork relative to the selector switch into a neutral position.
