Abstract
The invention relates to pressing tongs or crimping pliers (1). The pressing tongs or crimping pliers (1) comprise a fixed pliers jaw (4) and a movable pliers jaw (6). A closing motion of the movable pliers jaw (6) can be initiated by pivoting a movable hand lever (9) via a toggle lever drive (11). According to the invention, a further lever (48), especially in the form of an additional hand lever (49), is provided. The further lever (48) is coupled to the movable pliers jaw (6) in such a way that when the further lever (48) is pivoted, an opening motion of the pliers jaw (6) into an insertion and/or removal position can be initiated.
Claims18
Pressing tongs or crimping pliers for crimping or pressing a workpiece comprising:
- a) a fixed pliers part with a fixed hand lever and a fixed pliers jaw,
- b) a movable hand lever,
- c) a movable pliers jaw,
- d) a further lever,
- e) a drive mechanism,
- f) a drive connection and
- g) an insertion and extraction position, where
- h) the movable hand lever can undergo a pivoting motion towards the fixed hand lever,
- i) the further lever can undergo a pivoting motion and
- j) the movable pliers jaw can undergo a closing motion and an opening motion,
- k) the movable hand lever is coupled to the movable pliers jaw via the drive mechanism and the drive mechanism is configured to convert the pivoting motion of the movable hand lever towards the fixed hand lever into the closing motion of the movable pliers jaw, where when the closing motion of the movable pliers jaw is executed, the workpiece can be crimped or pressed,
- l) the further lever is coupled to the movable pliers jaw by the drive connection and the drive connection is configured to convert the pivoting motion of the further lever into the opening motion of the pliers jaw, where the opening motion of the pliers jaw brings the pressing tongs or crimping pliers into the insertion and extraction position, and
- m) wherein the further lever is an additional hand lever pivotally coupled to the fixed hand lever and positioned between an inner edge of the fixed hand lever and an inner edge of the movable hand lever.
