Double! Lift! Pliers

The invention relates to a pair of grip levers and a pair of double lever pliers, those for both external and internal locking rings can be used and when reversing the movement of the jaws anlenkbai the pair of jaw levers either above or below the jaw lever joint to the pair of grip levers is.

The invention is based on the object of such ' Double lever pliers with the aim of a simpler and clearer Handling at;:. Transfer the pair of jaw levers to improve.

This is achieved according to the invention in that aa pair of jaw levers a pair above and © in a pair below his Pivot pins arranged in pairs, each projecting in opposite directions, and a pair of levers on the handle One pair above and one pair below the Handle lifting joint arranged articulation holes arranged are and that the pair of jaw levers can be selected in one of its at both ends of the handle, the pair of levers can be turned. The reversal of puncture of the pair of baoken planes by modification no installation position, for which only dio. '. steering pins of the Baoken planer pair in the corresponding holes of the handle -.'..- pair of levers nuts are inserted, is clear and can be carried out quickly, with the double lever pliers at the same time characterized by an inexpensive manufacturability.

In a further development of the invention it is provided that there ~ Griffheoelpaar cranked in the area of its articulation bores and by one clamped between its handle levers Spreading spring is loaded, the spreading spring one to protruding over the G.r-iff lever joint, the einsccotzto pair of jaw levers from behind and against the handle pair pressing Eederungsbogen 'ufois.

A major advantage is also achieved by that did spreader spring is hairpin-shaped and on

their ends have long lugs, those on the handle thighs Projections with a non-circular cross-section are assigned. Due to this special design, the Peder can do a double job fulfill; because firstly, it spreads the handle lever and thus also the jaw lever or closes it depending on the turning position the Baoken lever pairs, and secondly, they complement that Pair of handle levers to a clamp, between the thighs the pair of baoke levers is held

In the preferred embodiment, handle lever joints are in alignment and Baoken lever joint roughly with each other

A cost-effective design results in particular from that the pivot pins are heavy-duty or grooved pins which are stuck in through holes of the pair of jaw levers and optionally protrude from this only on one side.

The invention is explained in more detail below with reference to the exemplary embodiment shown in the drawing. Included demonstrate : '

The forceps consist of their gruiid-ütsliohen structure from a pair of handle levers 2 (compare rig. 2), a pair of jaw levers 3 (compare Figs. $ And 4) and one needle-shaped curved spring J? (compare Fig. 1 \ ind 5)

The pair of handle levers 2 consists of two handles 21, 22 made of sheet steel, with the handles often made of plastic. The two handles 21, 22 are connected by a gold rivet at the pivot point 2-r -.

Pair of anchor pins 52 »53, 54, 55, with the upper Pair of pivot pins 52, 53 and the pair of pivot pins below © 54, 35 each in opposite directions abstain from the "two main sides of the Baokenhsbelpaen. The pivot pins are pre-eye orphans around dowel pins or grooved pins that are inserted into the through holes of the Jaw lever pair and protrude alternately sometimes on one side and sometimes on the other side from the pair of jaw levers.

The hairpin-shaped spring 5 has elongated ones at its ends eyelets 51, which are provided on the handle legs 21, 22, Lenses 211, 221 also elongated in cross section take up ^ The Peder 5 is also with an offset 52 and acts as an expanding spring for the handle lever pair 2, v / obei her foderungsbogen 55 up over the joint 24 of the handle lever pair protrudes.
