    • 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.
    • 本发明涉及一种手动工具,其包括第一腿部(1)和第二腿部(2),由此相应腿部的前部分别形成工具部分(3和4),并且相应腿部的后部产生夹紧 部分(5和6)。 至少一个腿部的抓握部分(5)包括套筒(10)形式的外部部件,该外部部件装配在与工具部件(3)连接的内部部件(9)上。 此外,手工工具包括至少一个具有第一可自由移动端部(13)的弹簧部分(12)和牢固地保持在所述套筒(10)上的第二端部。 该弹簧部分(12)旨在在使用该工具挤压在一起之后将腿部(1,2)分开再次移动。 根据本发明,所提到的一个腿的所述套筒(10)用于用于弹簧部件(12)的至少两个位置的引导件(16,17,18)执行,其中第一引导件(16)限定 第一位置是弹簧部分(12)的不起作用的位置,其中在使用中不对腿部(1,2)施加任何分离力;以及第二引导件(17,18),其限定作为活动位置的第二位置 对于弹簧部分(12),其中由于弹簧部分的第一自由端部分(13)与相对的腿部抵接,其在使用中在腿部(1,2)上施加分离力。
