摘要： An assembly of a barrel adaptor and a hammer bit, and components thereof, for use with a hydraulic hammer. The barrel adaptor is coupled about the hammer bit by means of a pin, and includes a cylindrical body, a ledge formed between an upper segment and a lower segment of the cylindrical body, and a pair of apertures extending through opposing sides of the cylindrical body and aligned with a keyway of the hammer bit, through which the pin extends in coupling. A sleeve is movably secured about a portion of the upper segment of the cylindrical body. Affixed within the bottom of the cylindrical body are one or more steel plates, and at a distal end a nosepiece, with a tooth removably affixed to the nosepiece.

摘要： The present invention relates to a hydraulic breaker. The valve is installed on an inner surface of the cylinder bush and the cylinder inner diameter portion to be movable in the vertical direction. The valve includes an upper valve portion having an upper end surface on which the pressure of the upper cylinder chamber acts, a lower valve portion having a lower end surface on which the pressure of the upper cylinder chamber acts, a first valve expanded-diameter portion which is formed between the upper valve portion and the lower valve portion, of which an outer diameter expands to be greater than outer diameters of the upper valve portion and the lower valve portion, and in which a first upper valve hydraulic pressure area communicates with the first and second flow channels, and a second valve expanded-diameter portion which is formed between the first valve expanded-diameter portion and the lower valve portion, of which an outer diameter expands to be greater than an outer diameter of the first valve expanded-diameter portion, and in which the second upper valve hydraulic pressure area communicates with the fourth flow channel, and the pressure of the valve switching chamber acts on a lower valve hydraulic pressure area having an area greater than an area of the first upper valve hydraulic pressure area.

摘要： Disclosed herein is a post repair kit comprising a stake defined by a body, proximal end, and a tapered anchor end. The post repair kit comprises a hammer mechanism comprising a power portion and a reciprocating ram structure, the power portion forcibly driving the reciprocating ram structure in a reciprocating motion. The reciprocating ram structure comprises a rod structure having a proximal end coupled with the power portion. The reciprocating ram structure further comprises an offset member connected to a distal end of the rod structure. The offset member has a first hole and a second hole. The distal end of the rod structure is connected to the first hole, wherein the offset member and the rod structure are connected perpendicular to each other. The reciprocating ram structure further comprises an interchangeable adaptor end tool detachably connected to the offset member using a fastening mechanism at the second hole.

摘要： An electric hammer includes a housing, an electric motor, an output assembly, an impact assembly, a mounting shaft, a clutch assembly, and a switching assembly. The mounting shaft is rotatable about a second axis. When the electric hammer is in the drill mode, a sleeve of the output assembly rotates. When the electric hammer is in the hammer drill mode, the sleeve rotates and an impact block of the impact assembly reciprocates in the sleeve. The switching assembly is configured to switch the clutch assembly between a first state and a second state and includes a switching element. The switching element includes a forced end and a drive end, the output assembly moving along a first axis drives the forced end to move, and the drive end is configured to drive the clutch assembly to be switched to the first state.

摘要： A multifunctional substrate repair tool that has a linear body and a plurality of implements on both ends. A head on one end houses a nail claw and ports for selective attachment of blades on the sides and on the top. The ports connect one or more arced blades, each having a striking surface, for penetrating and breaking apart substrate filler layer. Repeated strikes encompassing the fastener head removes filler layer material. A grip connects the head to a bulbous end having at least one of a peen and a protrusion. These are used to indent substrate features and, together with an optional abrasive surface, also located on bulbous end, to dress the cavity left by the blade and nail claw functions. The bulbous end is used as a strike surface for blade and indenting features alike.

摘要： A mortising kit for hinges, locks, strike plates, and the like can include a guide attachable to a subject to be mortised (e.g., door or door jamb). The kit can include a chisel that interacts with locating features of the guide to ensure proper placement of the chisel. Force applied to the chisel can score or otherwise cut the subject to a desired depth, at which point stops or other features of the guide can limit the chisel from scoring or cutting deeper. Placement of the chisel at opposite ends of the guide allow the full mortise perimeter to be scored or cut. Excess waste material can be removed from between the mortise perimeter, such as through use of the block plane.

摘要： The present invention discloses an angle-adjustable crowbar that comprises a crowbar body and a crowbar head. The crowbar head includes a first hinge base and a second hinge base in a spaced manner, and a head of the crowbar body is rotatably mounted between the first hinge base and the second hinge base through an angle adjustment mechanism. The angle adjustment mechanism comprises a limit shaft penetrating through the first hinge base, the crowbar body and the second hinge base, a first tooth portion, a polygonal limit portion and a second tooth portion are sequentially disposed on an outer wall of the limit shaft in an axial direction. The angle-adjustable crowbar overcomes the defects that the limit strength of existing crowbars is weak, the tooth portion is unlikely to be damaged, and the crowbar head cannot be replaced.
