摘要： A tool bit assembly includes a tool bit having a shaft with a first working region disposed at a first end of the shaft and a first reduced diameter portion proximate the working region and disposed between a first shoulder and a second shoulder. A floating sleeve has a rear portion with a pair of opposed window openings, a front portion supporting a magnet, and a pair of balls, with each ball disposed in one of the window openings. The floating sleeve is receivable over the tool bit with the magnet proximate the first working regions and the balls received in the first reduced diameter portion to allow the floating sleeve to move between a first position in which the balls abut the first shoulder and a second position in which the balls abut the second shoulder.

摘要： A retainer device for a drill bit, an earth-boring drill assembly and methods of retaining a drill bit and operating drill assembly. The earth-boring drill assembly includes a casing having a central axis, the bit having a generally cylindrical head. The retainer device includes an annular sleeve connectable to the casing and a retainer assembly provided between the sleeve and the bit. The retainer assembly includes an axial slot defined by one of the sleeve and the bit, the slot having an axially-extending side wall defining an opening and an axial end wall, and a lug supported on the other of the sleeve and the bit, the lug being positionable in the slot through the opening in the side wall, the lug being engageable with the end wall to restrict axial movement of the bit from the sleeve and away from the casing.

摘要： A bit holder includes a shank, and a bit sleeve. The shank has a first end portion of a non-circular geometric equiangular cross-section for combining a hand tool, and a second end portion formed with a combining hole having female threads in its wall. The bit sleeve has a through hole for a bit to extend therein, male threads and a circular circumference. The bit sleeve is combined with the shank by engagement of the male threads with the female threads, and the bit sleeve may be rotated to fix with or loosen from the shank by an auxiliary tool for changing the bit. In assembling, the bit is inserted through the through hole of the bit sleeve, and then the male threads of the bit sleeve are engaged with the female threads of the shank by an auxiliary tool fitted with the circular circumference and rotated to keep the bit combined with the shank, with the bit sleeve pressing the bit so as to minimize the tolerance of the gap between them, thus enabling the bit to drive a screw smoothly into an object.
摘要翻译：一个位夹持器包括柄和位套。柄具有用于组合手工工具的非圆形几何等角截面的第一端部，以及形成有在其壁中具有阴螺纹的组合孔的第二端部。钻头套筒具有一个通孔，用于使钻头在其中延伸，外螺纹和圆周。钻头套筒通过阳螺纹与内螺纹的接合与柄组合，并且钻头套筒可以通过用于改变钻头的辅助工具从柄固定或松开。在组装时，该钻头通过钻头套筒的通孔插入，然后钻头套筒的外螺纹通过装配有圆形圆周的辅助工具与柄的内螺纹接合并旋转以保持钻头的组合与柄一起，钻头套筒压住钻头，以便最小化它们之间的间隙的公差，从而使钻头能够平稳地将螺杆驱动到物体中。

摘要： A pneumatic impact power tool has a tool body with a bit-receiving axial bore in its end surface. A cap is threaded on the end of the tool body and has an end wall spaced from the end surface to define a cavity and a lobed opening in the cavity matably receiving a like-lobed bit shank, the cavity being dimensioned to accommodate the lobes. Spring-biased balls project into the cavity from radial bores in the end cap to engage the shank lobes and bias them to a rotational position non-aligned with the opening lobes to inhibit removal. The cavity is dimensioned to afford a slight axial clearance to accommodate axial movement of the lobes. A cover on the end cap is recessed to receive the bias springs, retaining both the springs and the cover in place. The end cap has a annular channel communicating with an exhaust passage in the tool body and four exhaust ports in the end wall.
摘要翻译：气动冲击动力工具具有在其端面具有钻头容纳轴向孔的工具主体。帽被拧在工具主体的端部上，并且具有与端表面间隔开的端壁，以在空腔中形成一个空腔，并且该空腔中的一个裂片开口可配合地容纳类似裂纹的钻头柄，空腔的尺寸适于容纳凸角。弹簧偏置的球从端盖中的径向孔突出到空腔中，以接合柄凸起并将其偏压到与开口凸角不对准的旋转位置以阻止移除。该空腔的尺寸被设计成提供轻微的轴向间隙以适应叶片的轴向移动。端盖上的盖子是凹进的，以接收偏置弹簧，将弹簧和盖子保持在适当位置。端盖具有与工具主体中的排气通道和端壁中的四个排气口连通的环形通道。

摘要： A tool holder assembly includes a hollow supporting member on which there is threaded a locking ring which is urged to its locked position by a pair of parallel equal springs, there being a combined latch and release pin wherein the release pin is directly guided in the supporting member for holding the locking ring in the unlocked position, and responsive to the reception of a tool to be automatically released for automatically tightening the locking ring. The locking springs are disposed in groove means defined by structure which is comovable with the locking ring, the groove being radially outwardly and axially substantially open, and closed by an annular cover of L-shaped cross section telescopically received on the locking ring. The locking ring has a cylindrical flange with a cutout portion defining angularly spaced abutments that engage a stop on the supporting member against which the parallel springs act.
