Jack handle device

Abstract

The invention discloses a jack handle device comprising a hollow tube block and two handles connected with the hollow tube block. The hollow tube block is fixedly connected with the handles. The hollow tube block is a cylindrical hollow tube. The handles are disposed at two ends of the hollow tube block. Each handle is composed of two hollow tubes different in thickness and are telescopic, wherein the thick hollow tube is sleeved outside the thin hollow tube. The jack handle device can be a substitute for human hands, protects personal safety, and can be telescoped as required. The handles are composed of the hollow tubes, so that the weight of the jack handle device is reduced and materials are saved. The hollow tube block is 3mm-10mm in wall thickness, while the handles are 2mm-8mm in wall thickness. The jack handle device is convenient to produce, low in cost and simple to use.

Description

technical field [0001] The invention relates to an instrument handrail, in particular to a jack handrail. Background technique [0002] With the development of technology and the needs of processing, there are now more and more important processing machines. When these machines are installed, disassembled, and maintained, it may not be easy to move these large machines by manpower alone, so some external force is needed, and the jack It plays an important role in this aspect, but when in use, the stability of some equipment is not very good, so it is necessary to use someone to help the jack to prevent it from tilting, but accidents may still occur due to improper operation or other reasons If the equipment tilts or collapses, people have no time to respond at close range and in a short time, and it is too late to keep the hand and body supporting the jack away from the equipment, which is easy to cause injury to people.
