The present invention provides a blade-replaceable cutting tool, which includes: a first handheld portion and a second handheld portion; the second handheld portion is rotatably connected to the first handheld portion; and further includes a blade mounting plate and a blade, the blade mounting plate is rotatably mounted to the first handheld portion; the blade is detachably mounted to the blade mounting plate. Wherein, the blade mounting plate and the blade may be replaced with a ratchet blade which is detachably and rotatably mounted to the first handheld portion.

A ratchet clamp, comprises a first clamp arm, a second clamp arm and a ratchet mechanism provided between the first clamp arm and the second clamp arm. An elastic member is arranged between the ratchet mechanism and the second clamp arm. The ratchet mechanism includes a toothed bar, a pivoting member. The pivoting member includes a toothed piece, a housing and a lever. The self lock state of the ratchet clamp of the invention is very safe and stable, the maximum clamping force at the jaw opening portion can reach about 50 Kg, and 85% of the maximum clamping force can be maintained after the user releases the clamp arms.

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 multi-function tool includes a first handle, a second handle, a first cutting insert, and a second cutting insert. The first handle is pivotally coupled to the second handle at a pivoting axis. The first handle and the second handle move between an open position and a closed position relative to each other. A first insert surface is formed on the first handle, and a second insert surface is formed on the second handle. The first cutting insert includes a front side, a rear side configured to interface with the first insert surface, a left side including a flat anvil surface, and a right side including a cutting edge. A second cutting insert includes a front side, a rear side configured to interface with the second insert surface, a left side including a flat anvil surface, and a right side including a cutting edge.

The pipe pliers includes a first clamping body, a driving handle, and a clamping element. The first clamping body includes a body portion. The body portion includes two side plates and is formed with two guiding toothed grooves. A receiving groove is defined between the two side plates. Each side plate is formed with a sliding groove facing the other side plate. The driving handle is slidably arranged at the two guiding toothed grooves and is pivotable with respect to the first clamping body. The driving handle has a protrusion. The clamping element is slidably arranged at the two sliding grooves. The clamping element has a recess. The protrusion is rotatably inserted into the recess. When clamping a workpiece, the clamping element slides linearly.
