摘要： A foot rest for a post-hole digger and post-hole diggers using the foot rest are disclosed. The foot rest includes two portions, one attached to each shaft of the post-hole digger. The two portions have structure that allows them to engage one another when the two shafts of the post-hole digger are vertical. The foot rest does not extend beyond the bore diameter of the post-hole digger. Thus, in order to keep the user's feet on the relatively short foot rest, the contact surface of the foot rest may be angled. In some embodiments, the foot rest may be symmetrical, so that either side may be used as the upper surface. A post-hole digger including the foot rests typically includes at least two foot rests, spaced from one another and facing different directions along the shafts of the tool.
摘要翻译：公开了一种用于钻孔挖掘机的脚踏板和使用脚踏板的后孔挖掘机。脚踏板包括两个部分，一个连接到钻孔挖掘机的每个轴上。两个部分具有允许它们彼此接合的结构，当钻孔挖掘机的两个轴垂直时。脚踏板不会延伸超过钻孔挖掘机的孔径。因此，为了将使用者的脚保持在相对较短的脚踏板上，脚踏板的接触表面可以成角度。在一些实施例中，足底座可以是对称的，使得任一侧可以用作上表面。包括脚踏板的钻孔挖掘机通常包括至少两个搁脚板，彼此间隔开并且沿着工具的轴线朝向不同的方向。

摘要： The present invention is a light-weight, single handle post hole digger. The single handle of the post hole digger is generally comprised of an outer elongated vertical handle and an inner elongated vertical shaft located substantially within the outer handle. The post hole digger of the present invention has two blade members used to cut into the ground and to loosen soil when in an open configuration and then used to capture and remove soil when in a closed configuration. In some embodiments, a first stationary blade member is permanently attached to the inner elongated vertical shaft by an adjustable pin or bolt and a second movable blade member is connected to the outer elongated handle via a connection rod.

摘要： This invention provides a post hole digger having a first, traverse pivot point, located on the lower section of two handle members, and a second, blade assembly pivot point located at the medial point of the blade assemblies. Because the first pivot point is a traverse pivot point, the handle members are only required to travel through a limited range of motion. Additionally, the second, blade assembly pivot point is preferably an offset pivot point. Thus, because the second, blade assembly pivot point is disposed at a medial point the blade assemblies, the motion of the handle members, which are coupled to the upper ends of the blade assemblies, is reversed relative to the lower ends of the blade members.
摘要翻译：本发明提供了一种钻孔挖掘机，其具有位于两个手柄构件的下部上的第一横向枢转点和位于叶片组件的中间点处的第二刀片组件枢转点。因为第一枢轴点是横动枢轴点，所以只需要把手件移动到有限的运动范围内。另外，第二刀片组件枢转点优选地是偏移枢转点。因此，由于第二刀片组件枢转点设置在刀片组件上的中点处，与刀片组件的上端相连的手柄件的运动相对于刀片件的下端是相反的。

摘要： A drilling machine comprises a power motor unit coupled with a spiral rod and a drill bit shaft and assembled in a mounting frame using a positioning disc. The arbor of power motor mounted on the mounting frame directly drives the drill bit shaft. The spiral rod is disposed at the periphery of drill bit shaft. A plurality of cutters are arranged between the drill bit and spiral rod at the outer perimeter of drill bit with a hollow guide notch above the cutters. The spiral rod is mounted in the positioning disc and engage a plurality of planet gears. When the arbor of power motor turns, it directly drives the drill bit shaft, drives the fast turning of drive gear at the periphery of drill bit shaft, resulting in different turning speeds with the drill bit shaft turning slowly and the spiral rod turning fast.

摘要： An auger stabilizer includes a rigid elongated body having a first end and a second end. The length of the body is adjustable between a retracted transport position and an extended drilling position. A pair of spaced apart wheels are attached at the second end of the body. A split body with two halves connected by fasteners is used to pivotally attach the first end of the body to a handle of an auger. When the body is in the extended drilling position, the pair of spaced apart wheels roll along a ground surface away from the auger as the handle of the auger descends and the pair of spaced apart wheels act to stabilize the handle of the auger against reactive torque.

摘要： A dog-type recoil actuated auger enables holes to be drilled by using only straight line motions of a person's hand, arm, and shoulder. The recoil actuated auger is comprised of a recoil drive system connected to a shaft, which in turn is connected to an auger. The recoil drive system has a recoil mechanism that imparts unidirectional rotation to the auger in response to bidirectional rotation of the recoil mechanism. The recoil mechanism may have dogs that engage a drive cup, or clutch bearings, to unidirectionally rotate the auger. The recoil drive system has a handle that the person grasps during operation. Operation is achieved by pulling a rope wound around a rope wheel. A recoil spring rewinds the rope after a pulling motion. Multiple recoil mechanisms assembled to the shaft and a suitable handle enable more than one person to operate the recoil actuated auger at the same time.
