The accommodating base is accommodated in the through hole and includes a bottom portion and a surrounding wall. The bottom portion is located at an outer end of the through hole and covers the through hole. The surrounding wall is connected to the bottom portion and located in the through hole. The surrounding wall and the bottom portion surround an accommodating space. The abutting element is disposed in the accommodating space.

Abstract: A socket structure includes a body, a first fitting hole, a second fitting hole, and at least one elastic engaging member. The first fitting hole is disposed at one end of the body. The second fitting hole is disposed at another end of the body. The at least one elastic engaging member is disposed in the first fitting hole and protrudes toward an inner portion of the first fitting hole along a radial direction of the first fitting hole. When a tool is inserted into the first fitting hole, the at least one elastic engaging member is pressed and deformed by the tool and is thus engaged with the tool. The configuration of the at least one elastic engaging member makes it easier to connect a tool to and remove the tool from the socket structure.

Abstract: A wrench sound seat lubrication structure includes: a seat member having an oil receiving space formed at a hollow internal thereof, a top end of the seat member having an opening formed thereon; one or a plurality of through holes formed to penetrate through a side wall of the seat member and fluidly connected to the oil receiving space; an actuating member pivotally attached to the opening on the top end of the seat member. The user is able to store a lubricant oil inside the oil accommodating space in advance. During use, the lubricant oil is slowly released from the through holes and the top opening, allowing the outer side of the seat member to be lubricated for a long period of time, thereby prolonging its useful lifetime.

Abstract: An anti-rolling socket includes a socket body, a groove, a through hole, and a stopper. The socket body has an inner peripheral surface and an outer peripheral surface. The groove is disposed in, and along the circumference of, the inner peripheral surface.

The switch is provided in the through space and is electrically connected to the light bulb. The positioning ball is movably provided in the radial through hole. The switch and the positioning ball are so structured that by mounting the socket on the connector main body, the light bulb can be turned on to enhance the efficiency with which the socket can be operated in the dark.

Abstract: A socket includes a main body. The main body includes an output surface, an outer annular wall, and a resistance structure. The output surface is located at one end of the main body, surrounds an opening of the main body, and is perpendicular to a driving axis of the socket. The outer annular wall is connected with the output surface and includes an operating portion. The resistance structure is located on, and extends annularly along, the output surface. When an operator tries to remove the socket from a hand tool, the socket provides increased friction between the operator's hand and the output surface and therefore can be securely gripped.

The sleeve includes a first ratchet portion, a second ratchet portion, and a non-ratchet portion located between the two ratchet portions. The sleeve can be selectively displaced relative to the rod to a first position, where the connecting portion is connected with the second ratchet portion, or a second position, where the connecting portion is adjacent to the non-ratchet portion. By controlling the relative positions of the rod and the sleeve, the driving state of the wrench structure can be switched.
