A tool includes a first body, a rotary member, a positioning unit and an engaging unit. By the positioning unit and the engaging unit, the rotary member is positioned relative to the first body with dual-positioning feature. When the first body is rotated, the rotary member is positioned by the positioning unit and the engaging unit. The rotary member is not likely to freely rotate because both of the positioning unit and the engaging unit fail when using the tool.

Provided is a removable safety-locking device or safety clip for use with multifunctional tools in a car functioning as a cigarette lighter socket adapter, safety hammer and cutter. The safety-locking device has a flexible clip body that engages with the multifunctional tool to prevent accidental firing of the safety hammer or accidental injury or cutting by the cutter or blade. The flexible clip body has a substantially semicircular downwardly depending pair of arms and a knife-block formed at and extending from an apex of the pair of arms.

A tool includes a handle and a blade. The handle extends from a handle first end to a handle second end. The blade has a first surface and an opposed second surface and defines a cutting edge between the first surface and the second surface. The blade extends from a blade first end to a blade second end. The blade and the handle are rotatably coupled at the blade first end and the handle first end about an axis extending from the first surface of the blade to the second surface of the blade. The blade is rotatable from a first position to a second position. The blade is lockable in the first position. When in the first position, the blade extends out from the handle second end.

Crimping pliers include a clamping assembly including a left jaw and a right jaw, a control mechanism, and a rotating button mechanism. The left jaw includes a left connecting portion and a left head. The right jaw includes a right connecting portion and a right head. The control mechanism drives the clamping assembly to switch between a clamping state and an open state. The rotating button mechanism includes a first connecting plate connected to the right connecting portion, an eccentric shaft, a rotating button connected to the eccentric shaft, and a limiting structure connected to the rotating button to limit a rotating range of the rotating button. The first connecting plate is rotatably connected to the left connecting portion through the eccentric shaft. The rotating button adjusts a distance between the left connecting portion and the right connecting portion by driving the eccentric shaft to eccentrically rotate.
