A multifunctional tool includes a docking frame which includes a first body having a front end portion and a second end portion extending inclinedly rearwards from the first body, a first actuation assembly which includes a first coupling unit and an engaging head mounted to the first end portion of the first body by means of the first coupling unit and has an engaging opening formed and defined between the engaging head and the first end portion of the first body, and a second actuation assembly which includes a first coupling unit and a cutting element pivotally and movably mounted to the second body by means of the second coupling unit. The multifunctional tool integrates various functions of multiple tools in one body while various function tools thereof compactly arranged together to form a simple and compact structure.

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.

The present invention discloses a multifunctional folding spade, which comprises a spade plate and a spade handle, a turntable is welded at the tail end of the spade plate, a spade handle sleeve is provided at the head end of the spade handle, a socket is provided at the head end of the spade handle sleeve, a part of the turntable body is inserted into the socket, the turntable and the spade handle sleeve are provided with matching rotation holes, and a pin shaft passes through the rotation holes to realize the rotating connection between the turntable and the spade handle; the turntable body is further provided with a plurality of angle adjusting holes circumferentially, a locking hole is provided with at the tail end of the spade handle sleeve correspondingly, a locking bolt is provided at one side of the locking hole.

A combination clamp and wrench tool includes a main body, a fixed jaw attached the main body, and a floating clamp mechanism. The floating clamp mechanism may include an adjustable jaw. The floating clamp mechanism may be attached to the main body such that the floating clamp mechanism is slidable relative to the main body towards and away from the fixed jaw. The worm gear and the rack are attached to the floating clamp mechanism. Actuation of the worm gear moves the rack linearly relative to the floating clamp mechanism. When the rack is moved to contact the fixed jaw, the combination clamp and wrench tool operates in a wrench mode, and when the rack is moved away from the fixed jaw, the combination clamp and wrench tool operates in a clamp mode.

A multi-tool includes a pair of plates having respective handle portions, joint portions, and head portions, with the plates pivotally connected to each other at the joint portions, and to be pivoted relative to each other to establish an open position and a closed position of the plates. A bit holder is extended from an end of one of the plates, with the bit holder including a socket to receive an insert bit, the handle portion of the one of the plates including a storage area to receive and store the insert bit, and, in the closed position of the plates, the plates to overlap each other with the handle portion of the other of the plates to cover the storage area and the handle portion of the one of the plates.

A tool is provided in order to facilitate utilization by users in a wide variety of applications. By way of example, a multipurpose tool may include first and second handles configured for relative movement between a closed position and an open position. At least the first handle includes an axle extending thereacross. The multipurpose tool also includes one or more tool members rotatably mounted upon the axle and foldable into the first handle and first and second jaws rotatably connected to the first and second handles, respectively. At least the first jaw defines an opening through which the axle of the first handle extends. The multipurpose tool further includes a resilient member disposed at least partially within the opening in order to apply a bias force to the first jaw during rotation of the first jaw relative to the first handle.

A multi-tool includes a body having a top face and a bottom face. At least one opening extends from the top face to the bottom face. The at least one opening is sized and configured to receive a finger of a user. A perimeter face connects the top face and the bottom face. The perimeter face includes a convex portion spaced from the at least one opening in a first direction. The convex portion is configured to contact a palm of the user. The body also includes two or more tools formed in the body.

A Shipboard Multi-tool. The Multi-tool includes a pair of groups of tools that are individually-extendable from the handle in order to allow the Multi-tool to operate a plurality of different shipboard mechanisms with a single assembly. One group of extendable tools includes spanner and box wrenches. Another group of extendable tools includes key-type wrenches. The individual extendable wrenches are lockable in a variety of angular positions relative to the handle to provide the user with several configurations with which to use the wrenches. The locking mechanisms are operable by depressing a spring-loaded push-button.

A chain master link tool includes a first lever and a second lever pivotally and releasably coupled together. Each of the first and second levers include a first working portions and a second working portion. The first and second levers are pivotal to an extended position in which the first working portions face oppositely and are disposed apart and cooperatively delimit a connection space therebetween for connection of a master link with a roller chain assembly and the second working portions face oppositely and are disposed apart and cooperatively delimit a removal space therebetween for removal of the master link from the roller chain assembly respectively.
