A fence post removal tool may include first and second arms, each of the arms having a handle and a working portion. At least one coupling member is pivotally coupled to each of the working portions. An opening defined by engagement surfaces provided in opposing faces of each of the working portions is provided and is configured to engage the surface of a fence post when in use.

The present disclosure provides self-adaptive laborsaving crimping pliers including a connecting handle, a movable handle, and a pliers head arranged on one end of the connecting handle and the movable handle. The connecting 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 connecting 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 connecting handle. Limiting portions are arranged on the elastic support arms. A tension spring is arranged between the limiting portions and the movable handle.

The invention relates to a pliers actuation assembly (1), pliers and a method of assembling a pliers actuation assembly (1). According to the invention, a locking pawl (85) has protrusions (89), a spring (86) has protrusions (92) and/or pulling bars (16, 17) have protrusions (14, 15) which are received in accommodations (90, 93, 12, 13) of hand lever plates (64, 65, 66, 67) in a joining direction vertical to the pivoting plane of hand levers (2, 3). The inventive design facilitates assembly of the pliers actuation assembly (1), while also enabling an at least partially automated assembly.

A compound pliers has a main joint pivotally connecting a right jaw to a left jaw; a right jaw lever extending from the left jaw and a left jaw lever extending from the right jaw; an auxiliary joint pivotally connecting a right handle joint lever to a left handle joint lever; a right handle joint connecting a right jaw lever to a right handle joint lever; a left handle joint connecting a left jaw lever to a left handle joint lever; and a right handle indent formed on the right jaw lever. The right handle indent receives an auxiliary joint protrusion. The auxiliary joint protrusion is formed around the auxiliary joint.
