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.

This utility model relates to the technical field of paleontological fossil excavation tools, specifically to a handheld excavation tool for collecting fossils in layered rocks. The handheld excavation tool includes at least a geological hammer, a steel chisel, and a steel crowbar integrated tool. The geological hammer includes a hammerhead body and a handle, with the hammerhead body located at one end of the handle. The bottom of the hammerhead body is a circular hammerhead, and the top is a wedge-shaped edge. The steel chisel includes a chisel body, with a chisel head at the upper end and a pointed tip at the lower end. The chisel body has anti-slip textures near the chisel head. The steel crowbar integrated tool includes a steel crowbar body, a crowbar rod, and an anti-slip handguard. The steel crowbar body is threadedly connected to the crowbar rod, and the crowbar rod has an anti-slip handguard inside its hollow end. This utility model's integrated tool of a geological hammer, steel chisel, and steel crowbar not only possesses high integration and versatility in function but also excels in durability, safety, and convenience, significantly improving the efficiency and safety of fossil collection and excavation work in layered rocks in the field.

A wallet includes a first shell with one or more openings on a shell perimeter adapted to clip one or more objects to the one or more openings; and a second shell coupled to the first shell, the second shell including a storage compartment; and first and second rails on each side of the second metal shell to slideably receive one or more cards in the storage compartment.

The invention relates to a band cutter (1, 101) comprising a body (4, 104) having an upper side (40, 140) with an anvil (2, 102) and a lower side (41, 141) with a blade (3, 103) having an elongated cutting edge (30, 130). The band cutter (1, 101) is configured to transmit, in use, an impact force received by the anvil (2, 102) to a band (B) located between a surface (S) and the elongated cutting edge (30, 130) of the blade (3, 103), thereby cutting the band (B).

The application discloses a chisel and relates to the technical field of building construction, which comprises a hammering part, a connecting part fixedly installed at one end of the hammering part, a head provided at one end of the connecting part, a blade and an inclined surface provided on the surface of the head, a V-shaped notch of the blade, V-shaped and arc-shaped settings of the two ends of the inclined surface, and an integrated head, and an assembling mechanism for assembling the head is arranged in the connecting part. The head comprises the blade and the inclined surface provided on the surface of the head, the notch of the blade is V-shaped, the two ends of the inclined surface are V-shaped and arc-shaped, and the head is integrally arranged, so that the head of the device can effectively transmit the force when the head is used for carving, the condition that the head is easily broken can be reduced, and the service life is improved, thereby reducing the use cost.
