Shears with spring at pass position of one blade

摘要

The shears have a bolt (6) passing through both blades. In the pass position of one blade (2) there is a relaxed spring (3) extending radially through the pass. It can be moved back in one direction radially from the pass. The spring holds the bolt more firmly in position in the blade (2). The spring can be made in one with the blade. The pass can be partly round and partly straight, with the spring acting on a straight sector of the bolt. Other shapes of pass are also possible. The spring may be at least partly parallel to a straight sector of the pass boundary (4), with an elastic end widening in the pass.
