摘要： An apparatus for sampling and collecting wood samples for analysis purposes which includes a boring bit surrounded by a chamber into which the boring bit draws samples and from which the samples are passed to a collection container. The boring bit is housed in a pair of slidably connected housing members which determine the depth that the boring bit enters a wood sample. Collected samples are analyzed for microbial contaminates.

摘要： A hand drill guide comprising an annular base and a plurality of telescopic leg assemblies distributed along the base. Each assembly has a hollow cylinder, fixed perpendicularly at one end to the base, and a rod slidably mounted in the cylinder, the rod extending out of the cylinder through an opening. The drill guide also comprises an annular positioning head to which the other ends of the rods are fixed, and an annular drill holding assembly mounted for selective location on the cylinders. The rod has a retaining ring rigidly connected thereto at a given distance from its upper end to prevent the rod from escaping from the cylinder. A ring is floatingly mounted on the upper portion of the rod inside the cylinder and two springs act on the floating ring: one between it and the upper end of the cylinder and the other between it and the retaining ring, both springs being uncompressed when the retaining ring is adjacent to the bottom end of the cylinder. A stiffening annular member preferably interconnect the cylinders at their open ends. In addition, the positioning head is preferably provided with a manually operable finger which can be moved to show where the center of the drill guide is located, that is where the hole is to be drilled.

摘要： The improved dwell and depth attachment includes an elongate housing that is attached to a drill motor and has an output shaft that is movable longitudinally and rotatably in the housing for rotating a drill bit. A drive spindle is connected with the output shaft and extends through the housing. An elongated sleeve encircles the spindle and has an end that is engageable with the work piece. An adjustable depth control located within the housing is connected for movement with the spindle. A first portion of the control includes a threaded interior and has ten circumferentially spaced, radially extending holes therein. The control also includes a second portion that has a threaded exterior mating with the first portion and has ten slots equally spaced about the exterior. A stop screw or the like is removably located in one of the radial extending holes in engagement with the second portion. The holes and slots are arranged so that rotation of the second portion relative to the first portion by one slot changes the drilling depth by one-tenth of the screw amount caused by full rotation. Further, movement of the stop screw from one hole to the next changes the drilling depth by one-hundredth of the amount caused by one full rotation.

摘要： A protection tool for an electronic drill provides various functions when drilling is carried out. The electronic drill has a front end with a through hole located at the front end and a drill head extending through out the through hole. The protection tool is moveably mounted at the front end of the electronic drill along an operation direction. A guard plate includes a pore aligning with the through hole and provides pass way for the drill head. A supporting frame is assembled with the guard plate and is moveably mounted at the front end of the electronic drill along the operation direction, so that the guard plate is positioned at a variable distance from the front end according to the movement of the supporting frame with respect to the front end.

摘要： A countersinking device includes an internal bore positioner adapted for receipt by a bore defined by a workpiece. A driver rod engaged with the internal bore positioner extends outwardly of the bore through a bore opening. A centering chuck, engaged about and axially movable along the driver rod, is configured to engage the bore opening to cooperate with the internal bore positioner to align the driver rod along a longitudinal axis of the bore. A counterbore is engaged about the driver rod, opposite the centering chuck from the internal bore positioner. The counterbore is rotatable about and is configured to be axially advanced along the driver rod to engage the bore opening and countersink the bore. A countersink depth control arrangement is associated with the counterbore and cooperates therewith to countersink the bore to a predetermined depth. An associated method is also provided.

摘要： A working depth adjusting device includes an adjusting member, an intermediate member and an operation member. The adjusting member is supported on the front portion of the tool body and movable along the axis of the spindle, so that the position of the adjusting member can be adjusted relative to the tool bit with respect to a working depth direction. The intermediate member is rotatably supported on the adjusting member. The adjusting member moves in the working depth direction as the inmate member rotates. The operation member is operable to rotate relative to the intermediate member between a lock position and an unlock position. The intermediate member has a first engaging member. When the operation member is rotated to the lock position, the first engaging member engages the tool body, and the engagement of the first engaging member is maintained by the operation member, so that the working depth adjusting device can be prevented from being removed from the tool body. When the operation member is rotated to the unlock position, the first engaging member is disengaged from the tool body, so that the working depth adjusting device can be removed from the tool body.
摘要翻译：工作深度调节装置包括调节构件，中间构件和操作构件。调节构件支撑在工具主体的前部上并且可以沿主轴的轴线移动，使得可以相对于工具钻头相对于工作深度方向调节调节构件的位置。中间构件可旋转地支撑在调节构件上。调节构件随着停止构件旋转而沿着工作深度方向移动。操作构件可操作以在锁定位置和解锁位置之间相对于中间构件旋转。中间构件具有第一接合构件。当操作构件旋转到锁定位置时，第一接合构件接合工具主体，并且通过操作构件保持第一接合构件的接合，从而可以防止工作深度调节装置从工具体。当操作构件旋转到解锁位置时，第一接合构件从工具主体脱离，使得工作深度调节装置能够从工具主体移除。
