The engagement element is laterally integrated into a specific sidewall to provide additional gripping action. The first groove and the second groove are positioned offset from each other, along the bracing surface of the specific sidewall. The primary cavity and the secondary cavity each traverse normal and into the bracing surface from the first base to the second base.

A two-way ratchet wrench includes a wrench body having a ratchet groove located in a head at one end thereof, an accommodation chamber in communication with the ratchet groove, an accommodation hole above the accommodation chamber, a ratchet wheel mounted in the ratchet groove, a ratchet block mounted in the accommodation chamber and meshed with the ratchet wheel, a dial block rotatably mounted in the accommodation hole and operable to move the ratchet block between a first position and a second position, and a positioning device mounted in the accommodation chamber such that the ratchet block is held in the first position when the positioning device is abutted against the first recess of the ratchet block, or the second position when the positioning device is abutted against the second recess of the ratchet block.

A tool for torquing a regulator onto a cylinder of a portable cylinder assembly. The tool includes a nut and a socket. The nut is configured to fit around a body of a regulator of a portable cylinder assembly. As such, the nut has a first set of grooves that avoids one or more valve assemblies on the body of the regulator. The socket has a cavity extending therethrough such that the cavity consists of three sections: a top section, a middle section and a bottom section. The top section of the socket is configured to be coupled to a device that applies a torque force on the socket. The middle section of the socket is configured to avoid a case of the regulator which is disposed above the body of the regulator. The bottom section of the socket is configured to be coupled to the nut.

A ratchet wrench is provided, including: a main body and a handling assembly. The main body includes a head portion being assembled with a ratchet head and a handling portion remote from the head portion. The handling assembly includes a casing coveringly disposed on the handling portion, and the casing defines a receiving space which is configured to receive at least one object and has at least one opening disposed therethrough. Part of an outer surface of the handling portion is flush with or protrusive beyond the at least one opening, and a material of the handling portion is different from a material of the casing.

An assembly of a wrench and a socket. The wrench has a penetrating driving hole, which has a retaining ring mounted therein. The socket, having a front end and a tail end, comprises a socketing portion axially extended between the front end and the tail end thereof for driving a fastening element. The socket comprises a retaining portion formed on the periphery thereof. The retaining portion has a retaining groove arranged at retaining corners radially indented for matching the retaining ring. The retaining groove is positioned between the front end and the tail end. The retaining portion further has a buffer groove formed between the retaining groove and the front end, so as to allow the buffer groove to successively provide a buffer or damping effect with the retaining ring when the retaining groove is decoupled from the retaining ring. Accordingly, the user is allowed to control his/her force more easily and improves the operational safety for the process of pulling out of the socket.

A unidirectional ratchet wrench structure has a wrench member, a pawl and a ratchet. The wrench member has an accepting space for accommodating the ratchet and an accepting space for accommodating the pawl. A toothed section of the pawl has a plurality of equiangular teeth and an irregular tooth. Since the irregular tooth is lower than the height of the equiangular teeth, the irregular teeth irregular tooth is capable of quickly disengaging from the equiangular teeth of the ratchet. The arc section and the toothed section have different arc measures and not push against the outer periphery of the ratchet at the same time, through the abutment of the pivoting point and the change of the center of gravity of the pawl when the wrench is rotated, the pawl is capable of producing a seesaw yaw movement to achieves the effect of quick engagement and disengagement.

A golf club wrench with a bit portion having a plurality of tip features at one end of the bit portion is disclosed herein. The tip features may include threading, a Philips head shape, a flat head shape, a Torx® head shape, and a hex wrench shape. The different tip features on the wrench can be used to engage with both a mechanical fastener and a weight. The wrench may also include a handle contoured to fit within the hand of a golfer. The golf club wrench can be provided in a kit containing weights and mechanical fasteners having engagement features that mate with one or more of the tip features on the wrench.

A method for connecting a screw and a rotary tool in a rotationally fixed manner, wherein the drive surfaces of the driving profiles have a constant inclination relative to their profile axis, which is the same for all drive surfaces of both components. In the component with the outer driving profile, the drive surfaces are all concave or all convex, and in the component with the inner driving profile, the drive surfaces are curved complementary to the drive surfaces of the outer driving profile, in such a way that, in the plugged-together state, the drive surfaces of the two components, viewed in the circumferential direction, come into surface contact/engagement with one another on both sides of the apex of the concave/convex curvature. The driving profiles are designed in such a way that they do not come into contact with each other in the transition regions located between the drive surfaces.

A hand tool for driving a fastener is provided. The hand tool includes gearing that interconnects a splined socket to a rotatable or trigger actuator and increases a rotational speed of the splined socket relative to the actuator. The hand tool may include a power tool receiver 38 or an independent motor to drive rotation of the splined socket to advance or retract a fastener from a threaded shaft. By increasing the speed and conserving rotational inertia, the hand tool reduces the time to secure a fastener on a threaded shaft. A rotatable nut is provided. The rotatable nut can slideably orient along a first axis and threadedly orient along a second axis to fasten to an adjacent surface.

A hand tool is provided, including: a first member; a second member; a shaft, connected with the first member, rotatably inserted to the second member, including positioning slots; and a control member, disposed on the second member, including at least one tooth; wherein the control member can be released by disengagement of the at least one tooth from the positioning slots so that the first and second members are rotatable relative to each other, and the control member can be locked by engagement of the at least one tooth within at least one of the positioning slots so that the first member is non-rotatable relative to the second member; wherein when the at least one tooth is engaged within at least one positioning slot, at least one blocking wall of the tooth is in gapless surface contact with at least one side wall of the slot.
