Abstract: A multi-angle cutting saw that can protect saw teeth from damage, perform multi-angle cutting, and is easy to transport, is provided. The saw includes a handle, a locking bolt, a saw blade, a guide block, and a return mechanism. The saw blade can be installed in the horizontal saw blade hole of the handle through the locking bolt. The guide block, which can be parallel to the saw blade and can rotate along with the saw blade and can penetrate through the handle, can be installed in the horizontal guide hole on the bottom surface of the horizontal saw blade hole in the handle. The saw blade can pass through the saw slot at the upper end of a support frame. The support frame, which can move along the saw blade together with the guide block, can be installed at the end of the guide block. The return mechanism, which is installed inside the upper end of the handle and can drive the guide block to move, can be connected to the spring clip at the other end of the guide block.

Abstract: A soil auger assembly that is easily disassembled and stored, and that can drill holes to any depth is provided. The soil auger assembly includes one or more augers, cutting blades, handles, extension rods, working shafts, and beveled tips. The cutting blade is wound spirally on the working shaft. The extension rod is integrated with the handle. The soil auger assembly further comprises at least one connection rod arranged between the extension rod and the working shaft. The connection rod can be connected via a slotted screw thread.

Abstract: A pivotable handsaw assembly in which the saw blade can pivot and be used to saw wood or other materials is provided. The pivotable handsaw assembly can be easy to use and the angle of the saw blade may be changed easily. The advantages of this pivotable handsaw assembly include its stability and the ease of replacing the saw blade when cutting to a fixed cutting depth.

Abstract: A method for producing a saw blade from one piece of material which will result in increased cutting efficiency of the saw blade, a simpler process for producing the saw blade and material reduction is provided. The method includes using a preset trace and a laser beam to simultaneously cut a piece of saw blade material into two saws; using a preset trace and a laser beam to process the sawtooth shape and the fine tooth structure, in which the sawtooth shape and the fine tooth structure form cutting blades with an oblique surface; and using a drill to punch a fixing hole at the top of the saw. The top of the cutting blades is formed in a curved shape, a rectangular shape, or a triangular shape.

Abstract: A tool handle assembly is provided. The tool handle assembly can include a handle with an outer casing and a chuck jaw. The chuck jaw is adapted to move back and forth, and is disposed outside a conical section formed at one end of the outer casing. The chuck jaw can be connected via friction between an inner surface of the chuck jaw and a conical surface of the outer casing. A longitudinal hole used for installing the tool can be formed at the center of the conical section of the outer casing. Advantages of the tool handle assembly include simple and safe use and faster attachment/detachment of a tool.

Abstract: A handsaw assembly that can prevent skin abrasion by reducing friction and heat between the handle and the hand of the operator is provided. The handsaw assembly includes a saw blade and a handle. The saw blade and the handle are connected by two rivets. Saw teeth are provided along one edge of the saw blade. There is a hand hole in the handle. The handsaw assembly includes at least two rows and two columns of through holes formed outside the hand hole of the handle.

Abstract: A packing box is provided. One paperboard is folded to form the packing box. Four sides and the top cover of the folded packing box can include two paperboard layers. The bottom of the folded packing box can include four paperboard layers. Advantages of the packing box include reinforced strength and a bottom that will not fail upon packing, storage, and transport of heavy bulk materials.
