    • A power tool (e.g. a laminate trimmer 10) includes an adjustable support for setting the position of the motor unit (16). The support includes a first collar element (24) secured to the motor and a support upright (14). A stud (32) threadedly secured to the collar is slidable in a slot (28) and co-operates with the slot (28) to maintain confronting surfaces (14a and 26a) of the elements in face to face engagement. The elements are thus constrained to slide only in a direction parallel to the upright (14). A clamping screw (36) threadedly engaged in the stud can be tightened to lock the adjustable support at a desired position. The arrangement provides high stability to permit adjustment of the motor position even when the motor is operating.
    • 电动工具(例如,层压修剪器10)包括用于设置电动机单元(16)的位置的可调节支撑件。 支撑件包括固定到马达的第一套环元件(24)和支撑件直立件(14)。 螺纹固定到套环上的螺柱(32)可在槽(28)中滑动并与槽(28)配合,以保持元件面对面的相对表面(14a和26a)。 因此,这些元件被限制为仅在平行于立柱(14)的方向上滑动。 可以拧紧螺纹地接合在螺柱中的夹紧螺钉(36),以将可调节支撑件锁定在期望的位置。 该装置提供高稳定性,以允许马达位置的调节,即使电动机运行。

    • A powered jig saw comprises a holder for a saw blade at the lower end of the reciprocating drive shaft. The holder is adjustable, by rotation of an actuating section, between an open position and a closed position for holding the saw blade. The actuating section comprises, in the interior of an upwardly open tube portion of the drive shaft, an engagement surface which, for the purpose of rotating the actuating section, engages with a working surface of a rotatable adjustment device which is stationary when the drive shaft is driven. The upper end portion of the drive shaft is mounted, so as to be capable of axial displacement, in a guide bush, above which there is a holding device of the adjustment device, in which holding device there is fixed a downwardly extending element comprising the working surface. A pendulum mechanism serves to generate a swivelling movement of the drive shaft. The guide bush, for the purpose of accommodating the swivelling movement of the drive shaft generated by the pendulum mechanism, is pivotally mounted within the housing and the holding device is supported on the guide bush and held in engagement therewith by spring force. In this way, tilting or swivelling of the engagement surface of the actuating section relative to the working surface of the adjustment device during the pendulum operation is prevented.
    • 动力曲柄锯包括用于在往复运动驱动轴的下端处的锯片的保持器。 通过致动部分的旋转,保持器可以在打开位置和用于保持锯片的关闭位置之间调节。 所述致动部分在所述驱动轴的向上开口的管部分的内部包括接合表面,所述接合表面为了使所述致动部分旋转的目的与所述可旋转调节装置的工作表面接合,所述可旋转调节装置在所述驱动轴 被驱动。 驱动轴的上端部安装成能够在导向衬套中轴向移动,在该衬套的上方具有调节装置的保持装置,其中保持装置固定有向下延伸的元件,包括 工作面 摆动机构用于产生驱动轴的旋转运动。 引导衬套为了容纳由摆动机构产生的驱动轴的旋转运动,枢转地安装在壳体内,并且保持装置支撑在导套上并通过弹簧力保持与其接合。 以这种方式,防止在摆动操作期间致动部分的接合表面相对于调节装置的工作表面的倾斜或旋转。

    • A jig saw 30 includes a housing 32 and a keyless shoe 54 which can be adjusted relative to the housing to selectively position a cutting blade 48 for effecting a cut perpendicular to the plane of a workpiece 66, or a cut which is bevelled with respect to the plane of the workpiece. A locking mechanism 58 includes a lever 60 which is formed with a locking section 170 having a wide cross section portion and a narrow cross section portion. When making an adjustment, the locking mechanism 58 is unlocked by pivoting the lever 60 so that the narrow portion of the locking section 170 is in a prescribed alignment. After making the adjustment to a desired relative orientation and position between the housing 32 and the shoe 54, the lever 60 is pivoted to the locked position. In this position, the wide portion of the locking section 170 is placed in a prescribed alignment whereby the components of the locking mechanism 58 are locked, or tightened.
    • 夹具锯30包括壳体32和无钥匙靴54,其可以相对于壳体调节以选择性地定位切割刀片48,以实现垂直于工件66的平面的切割,或相对于 工件的平面。 锁定机构58包括杆60,杠杆60形成有具有宽的横截面部分和窄截面部分的锁定部分170。 当进行调整时,锁定机构58通过枢转杆60而被解锁,使得锁定部分170的窄部分处于规定的对准状态。 在将壳体32和鞋54之间的所需相对取向和位置进行调节之后,杆60枢转到锁定位置。 在该位置,锁定部170的宽部被配置成规定的对齐方式,锁定机构58的部件被锁定或紧固。
