摘要： A system includes a utility chassis for use with rock drills for automatic and safe drilling of target surfaces. The utility chassis has a lightweight vertical frame member with an overall center of gravity that allows for manual lift handles to be arrayed about the center of gravity for easy loading and unloading onto transportation vehicles without the need for separate heavy machinery. The utility chassis incorporates a spring-centered closed position valve for drill rotation and a three-way spring-centered retract with two open feed positions valve for increased safety. A hinged drill rod guide cap is incorporated into the drill rod guide for quick removal of the chassis from lodged or broken drill rods. The chassis is lighter, more ergonomic, and safer than prior art chasses.

摘要： This utility type patent publishes a safety control device for petrol post hold digger. It includes an operation frame, respective handles in the opposite two sides of the frame; one is throttle control handle in the right side and another is balance control handle in the left side. The safety control device is mounted on the above of the frame near left side, connected with engine in the middle place of the operation frame by one cable, with the throttle control handle in the right side by another cable. A long touch rod is installed underneath the safety control device, sticking outside of the operation frame to position A as shown in bellow picture.When post hole digger is used, drill bit is driven into soul at clockwise direction. If the drill bit touches big roots or rocks and stops rotation in a sudden, all the inertia and torque from still running engine will be thrown to the operation frame, makes it turn to opposite anticlockwise direction. Then the touch rod, usually sticking out of the frame at position A, will turn to touch leg and rotate in a certain angle towards position B. Detecting this angle change, the safety control device will act and reduce the engine torque by releasing its throttle cable to get a lower speed. As a result, to avoid the operator's danger of falling down, make the machine always operate under comfortable control.This patent is designed to be safe in operation, simple in structure and high practical in use.

摘要： A tool for boring holes in soil includes an elongated tubular housing which has disposed through its length a bore having an upper opening coupleable to a vacuum source and a lower opening coupled to the bore of a ring-shaped bore head having circumferentially spaced apart cutting teeth protruding downwards from the bore head. A zig-zag shaped unclogger bar disposed coaxially through the bore head and rotated by a drive shaft disposed coaxially through the tubular and housing and protruding through a bearing in an upper end of the housing and driven by a rotary power source such as an electric motor fixed to the housing fragments lumps of clay or wet soil lodged in the bore of the housing, facilitating removal of soil and clay, which are severed by twisting the tool around its longitudinal axis by manipulating handle bars protruding from the upper end of the housing.

摘要： The present disclosure provides for a garden auger comprising a shank and an auger body. The auger body comprises a leading end and a trailing end including a space therebetween. The auger body is substantially radial including at least two legs connecting the trailing end and the leading end. The leading end has a cutter including a plurality of teeth forming a cutting diameter. The plurality of teeth each have a tip extending from the leading end, wherein the tips form a plane that is substantially perpendicular to an axis of rotation of the garden auger. The auger body is attached to the shank to prevent rotation therebetween. The shank comprises an attachment portion for attachment to a drill motor.
