Abstract
A universal wrench includes a handle that is made of flat parts that are connected by pins and are provided with a coating. The flat parts have clamping parts on their ends and have offsets which form a support slot for a clamping body. The clamping body has clamping surfaces and a bearing flange with support slot that has a varying diameter for a swivel axis which can move in recesses of the handle parts against a spring on which the wrench body pivots and is mounted in an adjustable manner in the gripping openings.

A universal wrench with at least one open wrench body, on the end of a handle for snug holding of a part that is to be gripped in such a way that the wrench body is held against the part that is being gripped and is pivotal and adjustable in a gripping plane relative to the handle, comprising:
- a forked end portion (1a) disposed on at least one end of the handle (1), defining an open slot (10) which receives a bearing flange extending from the wrench body,
- the wrench body (7,8) having a clamping surface (13,14) facing the forked end portion, the forked end portion including two prongs (1a and 1b) having free ends (1e and 1f) which are spaced apart to define the open slot (10) with each prong having an arcuate gripping surface (11) facing the clamping surface (13,14) of the wrench body, the arcuate gripping surfaces (11) of each prong (1a and 1b) being fluted;
- and
- a mounting arrangement for pivoting the wrench body (8) to the handle comprising a pin-in-slot connection (34 and 35) joining the wrench body (8) to the prongs (1a and 1b) wherein the gripping space is defined by a gap (12) between the clamping surfaces on the wrench body (8) and the prongs (1b and 1d).
