    • A chuck has a generally cylindrical body member having a nose section and a tail section. The tail section is configured to mate with the drive shaft so that the body rotates with the drive shaft. The nose section has an axial bore formed therein and a plurality of jaws is slidably positioned to engage a bit within the axial bore. Each of the jaws has a bit engaging jaw face formed thereon. One or more centering members are disposed adjacent to the jaws. The members are deformable from a first position where the members define a through passage configured to accept a bit, which has a drive shaft diameter less than a predefined diameter. The members are further configured to be deformable to a second position upon the insertion of a bit, which has a diameter greater than the predefined diameter, into the axial bore.
    • 卡盘具有具有鼻部和尾部的大致圆筒状的本体构件。 尾部构造成与驱动轴配合,使得主体与驱动轴一起旋转。 鼻部具有形成在其中的轴向孔,并且多个钳口可滑动地定位成接合在轴向孔内的钻头。 每个钳口具有形成在其上的有点接合的钳口。 一个或多个定心构件邻近钳口设置。 这些构件可以从第一位置变形,其中构件限定穿过通道,该通道构造成接受具有小于预定直径的驱动轴直径的钻头。 这些构件进一步构造成在将具有大于预定直径的直径的钻头插入到轴向孔中时可变形到第二位置。

    • A pressurized gas cartridge drives a dispensing device for viscous product cartridges. The dispensing device and the viscous product cartridge form a gas enclosure separated from a product enclosure by a movable wall. A valve is driven by a rack and pinion valve drive mechanism between an open position and a closed position upon rotation of the pinion. The rack rotates the pinion upon linear movement thereof. A trigger is adapted to impart linear movement to the rack upon manual actuation of the trigger. The open position of the nozzle valve permits viscous product to flow through the dispensing passage, and the closed position of the nozzle valve prevents viscous product from flowing through the dispensing passage. The interface between the trigger and rack is designed to operationally disengage rather than transmit a force therebetween that is capable of damaging the device.
    • 加压气体盒驱动用于粘性产品盒的分配装置。 分配装置和粘性产品盒形成通过活动壁与产品外壳隔开的气体外壳。 在小齿轮旋转时,阀门由齿条和小齿轮阀驱动机构驱动在打开位置和关闭位置之间。 齿条在其小直线运动时旋转小齿轮。 触发器适于在手动致动触发器时向机架施加线性运动。 喷嘴阀的打开位置允许粘性产品流过分配通道,并且喷嘴阀的关闭位置防止粘性产物流过分配通道。 触发器和机架之间的接口设计成可操作地脱离,而不是在其间传递能够损坏设备的力。
