The present disclosure provides self-adaptive laborsaving crimping pliers including a long handle, a movable handle, and a pliers head arranged on one end of the long handle and the movable handle. The long handle is bifurcated to form connecting arms rotatably arranged on the pliers head and elastic support arms. The connecting arms forms a linkage between the long handle and the pliers head. The movable handle is bifurcated to form movable connecting arms and elastic driving arms. The movable connecting arms are rotatably arranged on the pliers head and forms a linkage between the movable handle and the pliers head. The elastic driving arms are rotatably arranged on the elastic support arms to make the movable handle rotatably connect with the long handle. Limiting portions are arranged on the elastic support arms. A tension spring is arranged between the limiting portions and the movable handle.

A hand-held knockout driver includes a main housing having a handle portion, a motor positioned within the main housing, a pump assembly driven by the motor, and a secondary housing coupled to the main housing and defining a bore therein. The hand-held knockout driver also includes a working piston moveable within the bore from a rest position to an actuated position to define a piston throw distance therebetween. The hand-held knockout driver also includes a draw stud coupled to the working piston, a die coupled to the secondary housing, and a punch coupled to the draw stud opposite the working piston for movement therewith relative to the die. The die has a depth greater than the piston throw distance.

Crimping pliers for pressing cable shoes or the like onto electrical conductors, have two crimping jaws which can be pivoted towards each other, a crimping die being mounted rotatably in each crimping jaw, the crimping die being formed with multiple different crimping depressions over a circumference in relation to a rotation axis, and a crimping die held between two jaw plates in relation to the rotation axis. The crimping dies can be shifted relative to the jaw plates into a clamping position and a release position when the crimping pliers are assembled ready for use.

A crimping tool is disclosed. The crimping tool comprises a first handle, a second handle, a crimping member, a first mechanism link and a second mechanism link. The first handle comprises a hole and a first shaft portion, wherein the first shaft portion is adjacent to a top end of the first handle. The second handle comprises a second shaft portion, wherein the first shaft portion and the second shaft portion are connected by a shaft member. The crimping member is disposed on the first handle. The first and the second mechanism links are respectively connected with the first handle, the second handle and the crimping member such that when the first handle and the second tool are rotated with respect to each other, the crimping member is pushed to move from a first position to a second position.

Pressing jaws for opposite arrangement in crimping pliers, the pressing jaws having ribs, which extend in a rib longitudinal direction and move into each other during pressing. A guide surface extending transversely to the rib longitudinal direction outside of a working region of the ribs is formed, which guide surface interacts with a guide protrusion extending from the opposite pressing jaw. In another version, the pressing jaws have ribs, which are designed to mesh with each other and which have a rib longitudinal direction. Crimping pliers comprise two plier jaws, which are provided with oppositely arranged pressing jaws having ribs, which extend in a rib longitudinal direction and which, during pressing, move into each other and delimit a pressing jaw opening.

The invention relates to a hand pliers tool which might be embodied as crimping pliers, tube pressing pliers or cutting pliers. According to the invention, pliers pivoting parts are not (exclusively) connected to each other for being pivoted by bearing bolts arranged in bearing bores. Instead, pivot bearings are formed by bearing lugs having edge openings by which it is possible to insert a bearing pin into the bearing lug.

The invention relates to crimping pliers (1). The crimping pliers comprise a pliers jaw (4) on which a die half (22) is supported. A crimping force biasing the die half (22) is sensed by a force sensor. According to the invention, the force sensor comprises a piezo foil (36).

A pliers, configured to assemble an end cap to a vehicle cable, an end cap set including a plurality of end caps connected with one another, the pliers including: a main body and a connecting mechanism. The main body includes a first handling portion, a second handling portion and a receiving portion. The first handling portion is pivotally connected with the second handling portion. The first handling portion is movable relative to the second handling portion between a first position and a second position, and the receiving portion has a receiving space configured to receive the end cap set. The connecting mechanism is connected with the first handling portion and includes a cutting portion, a pressing portion and a feeding member. The cutting portion and the pressing portion correspond to the receiving space, and the feeding member is configured to move the end cap set.

A device head of a hydraulically actuatable tool includes an opposing holder which is integrally formed on the device head and which receives a first tool, and including a second tool that can be moved towards the opposing holder by a hydraulic piston. A cylindrical formation formed integrally with the device head and is provided relative to the hydraulic piston. The device head has an integrally formed toothing recess for the angular fixed, but also changeable, arrangement of a retaining rod.

The invention relates to a pressing tool, crimping tool or cutting tool (1; 2; 3) with a tool jaw (5) which is supported at a supporting body (24) by a guidance (28) having a remaining measuring degree of freedom (26). The tool jaw (5) is supported at the supporting body (24) in the direction of the measuring degree of freedom (26) by a mechanical parallel arrangement of an elastic supporting element (14) and a sensor (84). Here, the stiffness of the elastic supporting element (14) is dimensioned such that for the maximum of the effective working force of the pressing tool, crimping tool or cutting tool (1; 2; 3) the sensor (84) has a maximum deflection of at least 0.1 mm or at least 1.
