<p>This invention relates to handles for test instruments basically to aid in maintaining and adjusting the internal combustion engine of an automobile. In prior art devices, it has been necessary to lay the instruwent on the adjacent fender of the car or to prop it up within the engine compartment in some manner. It is apparent in many cases that the instrument is not firmly supported and that the instrument can be easily knocked off of its support and thereby damaged. Also, the only locations available for the instrument makes it very difficult for the mechanic to see the instrument. The present invention provides an adjustable handle for an instrument casing which can be readily moved. In the fully extended position, the handle can be hand gripped by the mechanic so that the face of the instrument can be held vertically for observation by the mechanic. When the handle is in the partially extended position, it provides a back support which holds the instrument at an angle for observation and when the handle is fully retracted, the instrument can be laid flat on its bottom as with prior devices. The leads for the instrument pass through the handle and through the bearings supporting the handle on the instrument so that the leads are never in the way of the operator when the handle is gripped by the operator.</p> |
