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: An elastic element includes an inner annular wall, at least one outer annular wall, and a groove. The at least one outer annular wall connects with the inner annular wall and surrounds the inner annular wall. The groove is formed between the inner annular wall and the at least one outer annular wall. The structural designs of the inner annular wall, the at least one outer annular wall, and the groove are such that when the elastic element is applied to a hand tool, the groove provides a space that allows the inner annular wall to be deformed, making it easier for a user to fit a to-be-operated object securely in the hand tool to enhance work efficiency.

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 through hole is disposed between the inner peripheral surface and the outer peripheral surface and communicates with the groove. The stopper includes a stop ring and a stop section. The stop ring is fitted in the groove. The stop section is connected to the stop ring. The stop section projects from the through hole and protrudes from the outer peripheral surface. The stop section can abut against a flat surface to prevent the socket body from rolling on the flat surface.

Abstract: A socket-driven lighting connector is configured to connect with a socket and includes a connector main body, a light bulb, a switch, and a positioning ball. The connector main body includes an enclosing wall and a radial through hole. The enclosing wall surrounds and forms a through space. The radial through hole penetrates the enclosing wall and is in communication with the through space. The light bulb is disposed in the through space. 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.

Abstract: An anti-vibration ratchet wrench includes a main body, a ratchet member and an elastic member. The main body includes a driving portion. The driving portion has a through hole and a driving axis. The ratchet member is sleeved in the through hole of the driving portion, and includes a ratchet tooth portion and an outer groove. The ratchet tooth portion is disposed around an inner annular surface of the ratchet member. The outer groove is disposed around an outer annular surface of the ratchet member. The elastic member is disposed in the outer groove, and located between the ratchet member and the driving portion. The ratchet member has a height along a direction parallel to the driving axis, and a disposed position of the outer groove is located between one third to two third of the height.

Abstract: A wrench structure with a variable driving state includes a rod and a sleeve connected to the rod. An outer surface of the rod includes an accommodating slot, an engaging block, an elastic element, and a connecting portion. The engaging block and the elastic element are disposed in the accommodating slot. The connecting portion is adjacent to the accommodating slot and surrounds the outer surface of the rod. 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.
