A cutting device includes: a first cutting blade in which a first opening and a second opening are formed; a first link in which an opening is formed; a frame in which an opening is formed; at least one of a first shaft member pivotably connecting the first cutting blade to the first link by being inserted through the first opening and the opening of the first link, and a second shaft member pivotably connecting the first cutting blade to the frame by being inserted through the second opening and the opening of the frame; and at least one of a first movement restriction member configured to restrict the first shaft member from moving in a direction of detaching from the first opening, and a second movement restriction member configured to restrict the second shaft member from moving in a direction of detaching from the second opening.

A multiple tool attachment system is adapted to be attached to demolition equipment. The system includes a universal body attached to the demolition equipment. A series of tools are independently attachable to the universal body. Each tool generally includes a bridge housing with a pair of jaws that are pivotable relative to one another and adapted to be attached to the receiving member of a universal body. The multiple tool attachment system is provided with quick change features designed to optimize strength and ease of removing and installing the bridge housing.

A tool includes a base; a guide member supported by the base, the guide member defining a longitudinal axis; an actuator coupled to guide member; a coupling rod supported by the guide member and functionally coupled to the actuator, wherein the coupling rod is operable to linearly translate responsive to input from the actuator, and wherein the coupling rod includes an attachment mounting surface; a spring supported by the guide member and contacting the coupling rod, wherein the spring is configured to bias the coupling rod toward a first position and configured to resiliently deform responsive to the actuator providing input to the coupling rod; and an attachment removably coupled to the attachment mounting surface of the coupling rod, wherein the attachment linearly translates in response to linear translation of the coupling rod.

A hydraulic power tool includes a housing defining a cylinder, a piston at least partially positioned within the cylinder and movable between a retracted position and an extended position, a clevis supporting a head of the power tool, a nut coupled to an outer peripheral surface of the clevis, and a collar coupled to the housing and surrounding the nut to axially constrain the nut between the collar and the housing while permitting relative rotation between the collar and the nut.

A blade removably secured to a jaw for a power tool includes a base at a first end, a tip at a second end opposite the first end, a cutting edge extending between the tip and base, and an alignment projection extending from the base away from the cutting edge. The alignment projection facilitates proper positioning and secure attachment of the blade to the jaw.
