The present specification relates to an electrically insulating tool cover assembly adapted to cover at least a front portion of a power tool, comprising a first and a second cover portion adapted to, in use, together cover the front portion of the power tool, and a releasable retaining element adapted to cooperate with a corresponding mating structure at the first and second cover portions, in order to hold the first and second cover portions together. The first and second cover portions and the retaining element are made of an electrically insulating material, such that in use, an electrical insulation may be provided for at least a part of the front portion of the power tool, and the first end is a front end of the tool cover assembly adapted to, in use, be arranged at the front end of the power tool.

A hand tool with insulation handle. The handle is made of an insulation material and is formed with a hollow portion (11) and an embedding groove (12). The embedding groove (12) is communicated with the hollow portion (11) and located on a front end (101) of the handle. The tool rod (20) includes a shaft (21) having a rear end (211) and a front end (212). The end plug (30) is made of the insulation material and includes a clamping section (31) and an abutting section (32). The rear end (211) of the shaft is positioned in the end plug through snapping the clamping section. The tool rod (20) is replaceablely inserted in the hollow portion (11) of the handle and protrudes from the handle.

An electrically isolated coupler may include a driven body, a drive body and an insulating member. The drive body is made of first metallic material and has a driven end configured to interface with a fastening component. The driven body includes a first interface portion and the drive body includes a second interface portion. The drive body is made of a second metallic material and has a drive end configured to interface with a driving tool. The insulating member is disposed between the drive body and the driven body to electrically isolate the drive body and the driven body from each. The first interface portion includes at least one axially extending portion that extends toward the drive body, and the second interface portion includes at least one axially extending portion that extends toward the driven body. The insulating member is disposed between the respective at least one axially extending portions of the first and second interface portions.

A tool, such as a ratchet tool, including a head portion having a cavity adapted to at least partially enclose a ratchet gear for providing torque to a working piece. Surfaces of the cavity and/or ratchet gear are provided with a compressive residual stress layer by a cold working process, such as, for example, shot peening.

An insulated screwdriver includes: an insulator, a first metal sleeve, a second metal sleeve, an insulated sleeve, and a handle. The insulator has a first connecting portion and a second connecting portion. The first metal sleeve is disposed on the first connecting portion of the insulator. The second metal sleeve is disposed on the second connecting portion of the insulator, and the second metal sleeve and the first metal sleeve are insulated. The insulated sleeve covers the insulator, the first metal sleeve, and the second metal sleeve. The handle has an accommodating hole for accommodating the insulated sleeve. According to the insulated screwdriver of the present invention, because the first metal sleeve and the second metal sleeve are insulated, there is no electric shock danger for a user, and safety in use of the insulated screwdriver of the present invention may be improved.

An electrically isolated coupler includes a drive body, a driven body, and a torque transfer assembly. The drive body is made of first metallic material and has a drive end configured to interface with a fastening component. The drive body includes a first interface portion and the driven body includes a second interface portion. The driven body is made of a second metallic material and has a driven end configured to interface with a driving tool. The torque transfer assembly is disposed between the drive body and the driven body to electrically isolate the drive body and the driven body from each other and transfer torque between the drive body and the driven body. The torque transfer assembly includes non-conductive material configured to maintain separation between the drive body and the driven body of at least about 0.400″.

An insulated multi-tool comprising a pair of opposing jaws, a pair of opposed handles operatively connected to the jaws relative to a pivot to force the jaws into a clamping position about an object, at least one of the opposed handles having a tool-receiving pocket, at least one tool stored in the tool receiving pocket, the at least one tool pivotally attached relative to the tool receiving pocket for movement between a stored position in which the at least one tool is stored within the tool receiving pocket and an open, use position in which the at least one tool is located relative to at least one of the opposed handles for use, and wherein the a pair of opposed handles are electrically insulated from both the pair of opposing jaws and each at least one tool.

An insulated tool gaiter with a non-conducting quick connect/disconnect coupling that can be coupled to a handle of a composite handled insulating tool. This allows a quick disconnect and reconnect to a number of different tools fitted with a corresponding coupling. The gaiter can be used in combination with insulating style tools to protect the technician. The insulated gaiter can be coupled to the tool at one end, and encapsulate or envelope the technician's hand, and is removably fixed at the other end with a cuff around the technician's forearm. The gaiter insulates the technician from arcing dangers while allowing the technician's hand to interface directly with the handle of the tool, allowing better control and grip that can otherwise be compromised when a technician is wearing thick, cumbersome insulating gloves.
