Problems solved by technology

However, it has been proved that although the pliers are perfect in mechanism, they are still defective in the structural shape of spatial action
The positions where manual pliers are used, such as the pipe ends to be connected, are often difficult to reach, so that the use of common manual pliers requires great skill from the fitter or is even impossible

Embodiment Construction

[0023] The manual pliers 1 is indicated as a whole by the reference symbol 1 in all figures. Its main components are two pliers legs 3 , 4 rotatably connected to each other on a first rotational axis 2 . The pliers legs 3 , 4 are divided into a tool section 5 on the side of the first axis of rotation 2 and a lever section 6 on the side of the first axis of rotation 2 . The handles 6 a , 6 b are each located at the end of the lever segment 6 . Like the second pliers leg 4 , the first pliers leg 3 is likewise divided into a lever 7 , 9 remote from the handle and a lever 8 , 10 close to the handle. The levers 7, 9 far away from the handle and the levers 8, 10 close to the handle are rotatable on the second 13 or the third 14 rotating shafts 13, 14 through the first 11 or the second 12 hinge joints 11, 12 respectively. interconnected.

[0024] In three different exemplary embodiments of the manual pliers 1 according to the invention, a tensioning mechanism 15 extends between th...

Abstract

The invention relates to a pair of manual tongs (1) comprising two limbs (3, 4) which are rotatably connected in a common first rotational axis (2). The first limb (3) is separated into two levers (7, 8) in its lever section (6), said two levers (7, 8) being rotatably connected in a first articulation (11), in a second rotational axis (13) parallel to the common first rotational axis (2). A means of traction (15) connects the second limb (4) to the lever (7) of the first limb (3), which is situated at a distance from the handle. Said means of traction can be shortened by means of a pivotal movement of the lever (8) of the first limb (3), which is situated close to the handle, about the second rotational axis (13). The areas of use of the manual tongs (1) are often difficult to access. According to the invention, the second limb (4) of the inventive manual tongs (1) is thus separated into a lever (9) situated at a distance from the handle and a lever (10) situated close to the handle and the two levers (9, 10) are rotatably connected in a second articulation (12), in a third rotational axis (14) which is parallel to the common first rotational axis (2).

Description

technical field [0001] The invention relates to a manual pliers having two pliers legs which are rotatably connected to each other on a common first axis of rotation, which each have a tool section on the side of the common first axis of rotation and a The lever section with the handle on this side of the common first rotating shaft, wherein the first pliers leg is divided into a lever away from the handle and a lever close to the handle on its lever section, and these two levers are parallel to the common first shaft. The second shaft of a rotating shaft is rotatably connected to each other with a first joint and a tension mechanism connects the second pliers leg with the end of the lever away from the handle of the first pliers leg, which is close to the handle. It can be shortened by turning the first pliers leg close to the handle lever around the second rotation axis. Background technique [0002] Such a manual pliers is known from German publication DE 36 17 529 A1. ...
