  • the tool thus has a relatively simple one Structure on, despite the simple structure a comparatively long Stroke of the toggle mechanism with an improved force / displacement ratio is achieved.
  • the middle Articulated member rotated about an axis by means of a drive device, whereby the toggle mechanism in a simple manner in the longitudinal direction the processing station can be stretched and contracted.
  • the drive device can be designed as a drive lever, which is coupled to the central joint member. With him you can comparatively small driving force a relatively large driving torque on the toggle lever. However, a could also be used as the drive device Motor are used, the shaft of which directly with the middle link is coupled by its central axis to thereby the To extend and contract the toggle lever mechanism by means of a motor, what the use of the tool in automated manufacturing enables. It would also be conceivable to couple the motor to the as Drive device serving drive lever.
  • drive lever and middle link can be preferred Embodiment of the invention also connected in one piece be what brings advantages in mass production, because then that middle link does not need to be manufactured separately.
  • the tool body and the drive lever each in handles.
  • the tool according to the invention can use the tool according to the invention as a hand tool become, which expands its possible uses.
  • the handles extend in the essentially in a direction transverse to the longitudinal direction of the toggle lever mechanism, which results in a more compact design of the tool results. This means that it can also be used in confined spaces.
  • the tool essentially exists from a device body 1, a processing station 2, a multiple toggle mechanism 3, the devices 2 and 3 in the device body 1 are housed, and from a handle-like drive device 4 to drive the multiple toggle mechanism 3.

  • the middle one Joint member 6 is rotatable about an axis 13 which is centered between the End points is attached to the joint member 6. With one end it is middle hinge member 6 at hinge point 9, which is a second pin 14th is formed, at the end not rigidly connected to the device body 1 of the articulated member 5 formed by means of a first rigid tab 15 articulated.
  • the middle joint member 6 is at its other end on the other hand by means of a third pin 16 at the hinge point 10 at one end the joint member 7, which is formed by a second rigid tab 17, articulated.
  • Joint members 5 and 7 In contrast to those formed by means of the rigid tabs 15 and 17 Joint members 5 and 7 is the joint member 6 through a distance S. formed a drive lever 18 and integrally connected to this.
  • the pivot axis of the handle 19 is the axis 13.
  • Another handle 20 is connected in one piece to the device body 1, in such a way that only the handles 19, 20 when the handle is open Articulated links 5 and 7 are essentially parallel to one another, while when the handle is in the closed position, all three joint links 5, 6, 7 essentially in a line in the direction of the longitudinal axis of the Multiple toggle mechanism 3 are located. Furthermore, stay with Transition from the open to the closed state of the handles 19, 20 the link members 5 and 7 essentially always parallel to each other.
  • the multiple toggle mechanism 3 described above is used for Drive of a first processing jaw 21, which is in the Processing station 2 is located and via a link 22 with the the other end of the articulated member 7 in the articulation point 11, which by means of a fourth rigid pin 23 is formed, is articulated. It is the link 22 slides in a guide 24 in one direction slidably, which is substantially equal to the longitudinal direction of the Toggle lever mechanism 3 is.
  • the processing jaw 21 is preferably interchangeable and rotatable with the axis of the link 22 coupled.
  • processing station 2 includes another, and preferably exchangeable second processing jaws 25, which with the Device body 1 coupled and rotatable at a point 26 on the device body 1 is stored.
  • a placed between the processing jaws 21, 25 The object can be made by corresponding embodiments of the processing jaws 21, 25 in a suitable manner, e.g. B. squeezing or cutting, be edited because of the stretching and contraction between the processing station 2 and the hinge point 8 lying multiple toggle mechanism 3 of the first machining jaws 21 on the second processing jaw 25 in the guide 24 controlled moved in / out.
  • the jaw 25 can on a tab 26a be stored, which is releasably attached to the front end of the tool 1.
  • the handle 19 is by a first tension spring 27 loaded by the handle 19 after reaching the closed Position of the handles 19, 20 returned to its starting position becomes.
  • One end of the tension spring 27 is with the device body 1 tightly coupled while its other end with an upper part of the handle 19 is connected.
  • a second tension spring 28 one with the free end of the tension spring 28 coupled ratchet member 29 and a ring gear 30 on the upper part of the handle 19, the handle 19 are gradually brought into the closed handle position, without it through the tension spring 27 before reaching the closed handle position is returned to the open handle position.
  • the the other end of the tension spring 28 is preferably connected to the device body 1 coupled stationary.
  • the ratchet member 29 can be rotated stationary with the device body 1 coupled and preferably designed so that it fits into the gaps of the Sprocket 30 snaps into the upper part of the handle 19, thereby a Spring back of the handle 19 is prevented by means of the tension spring 27.
  • the left part of the ring gear 30 is designed so that only after reaching the ratchet member 29 no longer in the closed handle position the gaps of the ring gear 30 snaps into place, causing both the ratchet member 29 and the handle 19 returned to its starting position will.
