The blade (200) is connected to an end (130) of the handle (100) in the first direction and is configured to extend from the end (130) in a second direction different from the first direction. The first striking surface (311) is provided on the opposite side of the end (130) of the handle (100) in the second direction and is configured to be struck from the opposite direction of the second direction. The second striking surface (321) is provided at the end of the handle (100) in the first direction and is provided in a third direction perpendicular to the second direction and is configured to be struck from the third direction.

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.

The utility model relates to the technical field of round handle chisels, and discloses a round handle chisel which comprises a chisel handle, a rotating barrel is slidably connected to the upper end of the outer wall of the chisel handle, a fixing groove is formed in the bottom of the inner side of the rotating barrel, fixing rods are fixedly connected to the left side and the right side of the upper end of the chisel handle, and two rotating grooves are formed in the inner wall of the rotating barrel at equal intervals. Rotating buckles are slidably connected to the inner sides of the two rotating grooves, chisel heads are fixedly connected to the tail ends of the multiple rotating buckles, two lifting grooves are formed in the left side of the inner wall of the rotating barrel at equal intervals, and a convenient clamping mechanism is installed at the lower end of the chisel handle and used for rapid installation of the chisel and equipment. According to the chisel, the proper chisel head slides to the position of the protrusion in the rotary barrel through the matching of the rotary buckle and the rotary groove, then the chisel head is pushed through the chisel handle to enable the rotary buckle to slide into the lifting groove, and then the fixing rod is clamped in the fixing groove, so that the effect of avoiding carrying a plurality of chisels in each work is achieved.

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.
