Wrench

You invention relates to a wrench with two pivotally mounted on each other around the key axis Grips and one rotatably mounted on this in the pivot axis. Ratchet wheel for the recording of tools such as plug-in nozzles »on the circumference of which there is a latch mounted on a lever» which is antriobsverbundan with the other lever.

Ee a wrench of this type is known in which the pawl for the ratchet wheel on a mounted coaxially to this pivotably arranged lever 1st, which is in the manner of a toggle lever with a Pressure bar is connected, which rests with its free end on the inside of a handle and is supported between its pivot axis and this end on an abutment of the other handle « If the handles have been moved towards each other, this will *

Tightening a screw With the help of such a wrench it is turned like a normal wrench when the handles are closed. As a result, however, the handles can be easily bent, especially because of the unfavorable lever arm of the Dxuekhöbols.

The invention is based on the object of designing a wrench of the type QQ described at the beginning, so that a large torque can be transmitted with it. The screw should be easy to assemble.

If the wrench is like a normal wrench, for example for tightening a screw, at relative to each other Fixed handles are used, the entire torque is transferred to the ratchet wheel via the locking member initiated, with this latching member being left in the longitudinal direction of the handle assigned to it, see above that the handle is only subject to tension Farner Mira avoided that during this training the handles are pushed apart when a torque is applied to the ratchet wheel, so that the wrench is easy to hold "
