Abstract
A blade clamp with first and second gripping members configured to hold a cutting blade, a lever connected to the clamp by a connection member, and a head that receives the connection member that extends through an aperture of the head. The connection member can move along a first axis through the aperture of the head and move the clamp along the first axis based on a position of the lever. The first and the second gripping members of the clamp can clamp the cutting blade along a second axis orthogonal to the first axis based on a position of the clamp along the first axis. The lever can include an eccentric cam surface that engages a cam follower. The eccentric cam surface can cause the clamp to provide a clamping force and tension to the cutting blade.
