摘要： A power tool having a housing, an electric motor disposed in the housing, and a spindle drivingly attached to the electric motor. The spindle includes a cavity adapted for receiving a bit therein and a window extending through the spindle in communication with the cavity. The power tool further has a retention device including a bit engaging member disposed within the housing and operable to extend through the window and retain a bit within the cavity. The power tool still further has an actuator operable by a user externally of the housing to disengage the bit engaging member from a bit received in the cavity and, finally, a mechanical interconnection system operably coupled between the actuator and the retention device to actuate the retention device in response to the actuator, wherein the mechanical interconnection is disposed within the housing.

摘要： A power tool assembly includes an anvil having an accessory receiving end portion that defines a detent bore. A detent is positioned in the detent bore and movable between a retracted position and an extended position in the detent bore. A biasing member is configured to urge the detent toward the extended position. The detent includes an upper detent portion having a trailing abutment surface, a trailing top surface portion, and a leading top surface portion. When the detent is positioned in the extended position, the trailing abutment surface and the trailing top surface portion are located outside of the detent bore, and the leading top surface portion is located within the detent bore. When the detent is positioned in the retracted position, the trailing abutment surface is located within the detent bore, and the leading top surface portion is located within the detent bore.

摘要： A safe and quick release device for a tool adapter includes a main body and a combination head. The main body has its front end axially bored with a combination groove with an open end. The combination groove has its opposite sides respectively bored with at least one position-limiting hole having its opposite ends respectively and annularly formed with a first position-limiting portion and a second position-limiting portion. A spherical position-limiting member is slidably disposed in the position-limiting hole and restrictedly positioned therein by the first and the second position-limiting portion. Thus, the position-limiting member is ready made, needless to be especially processed, can easily be in stalled for facilitating assembly and disassembly of the combination head, reducing processing cost.

摘要： A hand tool having an elongated plunger assembly that is rotatably and movably disposed in a socket. The plunger assembly can be rotated between a first orientation and a second orientation as well as being moved between a first, withdrawn position and a second, extended position. The plunger assembly also has an upper notch and a lower notch on a front side and at least one generally flat lateral side. A fixed latch member extends across a portion of the socket and defines a narrow passage within the socket. The hand tool, preferably, includes a compression spring biasing the plunger assembly toward the extended position.

摘要： A bit mounting device includes a holder that may be mounted to a spindle of the power tool or may be a part of the spindle. A bit push member is disposed within a bit receiving hole that is formed in the holder for receiving a tool bit. The movement of the operation member is transmitted to the bit push member via a transmission mechanism, so that the tool bit is pushed in a removing direction from the bit receiving hole by the bit push member.

摘要： A blade clamping device includes a driving shaft and a base member fixedly mounted to the driving shaft. An opening is defined in the base member and a blade is inserted in the base member and connected to the driving shaft. A cam member is pivotably engaged with the opening of the base member and a cam head contacts a side of the blade. The base member is received in a casing which is connected to the electric saw and an opening is defined in the casing. A lever is pivotably engaged with the opening of the casing and includes a pushing end which is located beneath a bar of the cam member so that when pivoting the lever, the pushing end pivots the cam member to remove the cam head from the blade.
