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.
