摘要： A switch assembly for a power tool including a switch member and a fixing part. The switch member including a finger grip part, a retaining part for retaining the switch member on a power tool, and an opening extending at least partially through the switch member, the retaining part arranged to project laterally with respect to an axis of the opening. The fixing part is arranged to be located in the opening. The switch assembly is arranged such that when the fixing part is at a first location in the opening, the retaining part adopts a retention configuration in which it projects laterally to a predetermined extent. When the fixing part is removed or at a second location in the opening, the retaining part adopts an insertion configuration in which it does not project laterally or projects less than the predetermined extent.

摘要： A reciprocating drive mechanism for a striker in a hammer, a rotary hammer, or a power drill having a hammer action, includes a sinusoidal cam channel formed on a drive member and a cam follower, in the form of a ball bearing, attached to a driven member which, due to the interaction of the cam and cam follower, results in a reciprocating movement of the driven member. Both the drive member and driven member can be rotatingly driven by a motor, their relative speeds resulting in the reciprocating movement of the driven member. The driven member is connected to the striker either via a mechanical helical spring or an air spring.

摘要： A drilling and/or hammering tool which includes a hollow spindle (1) and a tool holder (10) that can be attached to an end (18) of the spindle and removed therefrom. The toll holder comprises a tool holder body (14) which can be fitted within the end of the spindle and releaseably locked therein by means of at least one locking element (32) and a locking ring (42) for releasably holding the or each locking element in a locked position in which the locking element(s) lock(s) the tool holder to the spindle. The tool holder (10) comprises a manually actuable sleeve (40) for rotating the locking ring (42) in a first direction and for rotating the tool holder body (14) in a second opposite direction, and resilient means (62) for urging the tool holder body to follow the movement of the locking ring in the first direction and the locking ring to follow the movement of the tool holder body in the second direction. The resilient means urges the locking ring and the tool holder body into relative rotational positions in which the locking ring (42) holds the or each locking element in the locked position. The locking ring (42) has an internal radius that varies along its circumference so that rotation of the locking ring about the axis of the tool holder body will move it between a locking position in which it causes the or each locking element (32) to retain the toll holder body in the spindle, and a release position in which it will allow the or each locking element to move radially to release the tool holder body.

摘要： A tool holder for a power tool, in particular a drilling and/or hammering tool comprising a manually actuable sleeve (40) wherein components of the tool holder are held within the sleeve by a snap ring (100) which snap ring is fitted within the sleeve. The snap ring has at least one resilient arm (102) and the sleeve has a corresponding number of through holes (105) which extend to a radially outwardly facing surface of the sleeve, arranged such that the or each arm is engageable with a corresponding through hole in a snap fit. Each arm and through hole cooperate so that the portion (104) of the or each arm which can be viewed from the radially outwardly facing surface of the sleeve appears in the shape of a symbol. Thus, the snap ring (100) has the dual function of maintaining components, such as a locking ring (42) within the sleeve (40) and of providing an external indication to a user of how to actuate the sleeve.

摘要： A switch arrangement, particularly for a router, is provided with a switch and a pivotable trigger element in a handle arrangement, which can be pivoted against spring force from a release position into a switch operating position and on which is held in a displaceable manner a locking element which in an end position prevents the displacement of the trigger element in the direction of the switch operating position and which by engagement of a gripping area by hand can be displaced against spring force into a first position, in which the trigger element can be pivoted into the switch operating position so that the locking element in a second position locks the trigger element in the switch operating position. The trigger element is substantially L-shaped and is pivotably held at the free end of one of its legs. The locking element is pivotably held at the free end of the other leg and the gripping area of the locking element is located between a pivot connection with the trigger element and a connection area of the legs of the trigger element and at the side remote from the one arm. The locking element on the side with the gripping area is provided between this area and the pivot connection with a locking surface which cooperates with a countersurface of the handle arrangement and the locking element is provided on the side facing towards the one leg between the pivot connection and the connection area of the legs with a locking part which in the second position is in locking engagement with a locking portion of the handle arrangement.
