    摘要: The present invention relates to a tool for pipe bending comprising at least two branches (1, 3), at least one link arm (8), at least one former (7), and at least one sliding jaw (9), said at least one former (7) and said at least one sliding jaw (9) being intended to be placed on either side of a pipe (12) to be bent, and said at least one former (7) being fitted to, or constituting a part of, a first branch (1) of said at least two branches (1, 3) at the same time as said at least one sliding jaw (9) being fitted to, or constituting a part of, a second branch (3) of said at least two branches (1, 3). At least one of said at least one former (7) has at least one pipe-positioning index (18, 19), one of which is intended to be placed as close as possible to a corresponding bending-measure index on the pipe (12) when the pipe (12) is placed in the tool in order to be bent. The present invention also relates to a former (7) for use as a part of a tool for pipe bending.

    摘要: The invention relates to a hand tool comprising a first leg (1) and a second leg (2) whereby a front part of the respective leg creates a tool part (3 and 4 respectively) and a rear part of the respective leg creates a gripping part (5 and 6 respectively). The gripping part (5) of at least one of the legs comprises an outer part in the form of a sleeve (10) which is fitted over an inner part (9) connected with the tool part (3). Further the hand tool comprises at least one spring part (12) with a first freely moveable end part (13) and a second end part firmly held at the mentioned sleeve (10). This spring part (12) is intended to again move the legs (1, 2) apart after they have been squeezed together in using the tool. According to the invention the mentioned sleeve (10) of one of the mentioned legs is executed with guides (16, 17, 18) for at least two positions for the spring part (12), of which a first guide (16) defines the first position which is an inactive position for the spring part (12) where it does not exert any separating force upon the legs (1, 2) in use and a second guide (17, 18) defining a second position which is an active position for the spring part (12), where it exerts a separating force upon the legs (1, 2) in use as a result of the first free end part (13) of the spring part coming into abutment with the opposite leg.
