Abstract: A ratchet wrench is provided, including: a handle, a moving member and a positioning mechanism. The moving member is rotatably connected with the handle about a rotational axis and includes a driving head having a driving axis parallel to the rotational axis. The moving member is swingable between a folded position and an operating position. The positioning mechanism is disposed between the handle and the moving member and includes at least one restricting portion and a positioning member, and the positioning member is movable between a locking position and a release position. When the positioning member is in the locking position, the positioning member is interfered with one said restricting portion in a swinging direction of the moving member; when the positioning member is in the release position, the positioning member is free of interference with the at least one restricting portion in the swinging direction.

Abstract: A method for recycling EVA plastic foamed material may include steps of collecting excess plastic foamed compound; granulating through hot melt method; weighing and mixing granular plastic compound; rolling mixed compound into plastic film; and foaming plastic film to produce EVA foam mat. The excess plastic foamed compound can be recycled and reused in the present recycling method, which has environmental benefits and reduces the manufacturing cost. Also, the EVA foam mat, which is formed from the high-quality of the plastic film coupled between two unfoamed plastic mat bodies, has strong structural strength and prolonged lifetime, which prevents the EVA foam mat from deformation due to heavy pressure and protects the floor or tiles thereunder.

Abstract: A floor mat puzzle, forming a non-rectangular isometric polygonal mat, has a plurality of edges and a same number of corners as the edges, each corner disposed between two edges. Each edge has at least one engaging protrusion and at least one concavity, each edge further has a first corner protrusion and a second corner protrusion at two corners, and a corresponding first corner concavity and a corresponding second corner concavity provided respectively adjacent to the first corner protrusion and the second corner protrusion.

Abstract: A foam pad structure has a mat body having at least one surface layer, the surface layer comprising TPE, EVA and a cured. PE material as an integrally formed foam. The cured PE material has PE particles uniformly mixed in a composite foam layer formed b the TPE and the EVA materials.

Abstract: A high torque ratchet wrench includes a main body having a handle and a head, the head having a first, second, and third cavities; a ratchet wheel rotatably disposed in the first cavity and having plural teeth; a direction switching assembly movably disposed in the second cavity; a ratchet block movably disposed in the third cavity and between the ratchet wheel and the direction switching assembly; and two torque blocks disposed in the third cavity and facing the ratchet block. The ratchet block has two sides provided with a first and a second held surfaces. The direction switching assembly moves between a first and second positions to force the ratchet block to engage the ratchet wheel. When the direction switching assembly is at the first or second position, the first held surface or the second held surface is correspondingly pushed by one of the torque blocks.

Abstract: A socket ratchet wrench includes a main body, a ratchet ring, a direction switching device, an upper cover, and a clamp member. Therein, the main body has a handle and a head, and the head has a first lateral side and an opposite second lateral side, with a first containing groove passing through therebetween and connected with a second containing groove. The ratchet ring is rotatably disposed in the first containing groove and has a polygonal inner bore for receiving a socket. The direction switching device is movably disposed in the second containing groove for unidirectionally driving the ratchet ring. The upper cover is fixed on the first lateral side. The clamp member is pivotally disposed on the upper cover, capable of pivotally swinging between a clamping position and a releasing position against the upper cover to optionally clamp or release the socket.

Abstract: A ratchet wrench includes a body having a head portion, a handle portion extended from one end of the head portion, a first cavity and a second cavity mutually communicated in the head portion, a rotatable member rotatably accommodated in the first cavity having sloping teeth around the periphery thereof, a reversing member pivotally mounted in the second cavity defining opposing first and second bearing surfaces, a pawl set between the rotatable member and the reversing member having a shaft portion located between the first and second bearing surfaces and movable by the reversing member between first and second positions to force a toothed portion opposite with the shaft engaged with or disengaged from the sloping teeth, and a cover covering the cavities having a through hole for the passing of the rotatable member to rotate a wrench socket forward or backward.

Abstract: A ratchet wrench includes a wrench body, a driving ratchet, a change-gear set, a retaining lid and a positioning rod. The driving ratchet is configured to removably engage with a tool part. In virtue of the cooperation between the change-gear set and the positioning rod, when the wrench body is turned toward a predetermined direction of the tool part, the driving ratchet can rotate in an increased speed, thereby improving the efficiency of operating the tool part.
