[0018] Compared with the prior art, the utility model has the following beneficial effects:1. By setting up a support shaft mechanism, a reliable support is provided for the cable chain of the chain machine tool. The support shaft body is sleeved on the support shaft. The first arc groove of the support frame and the second arc groove of the fixed cross frame, together with the limit stop, can accurately fix the support shaft and ensure that the support shaft body can rotate flexibly. During operation, the rolling friction between the cable chain and the support shaft body replaces the traditional sliding friction, which significantly reduces friction, reduces cable chain wear, and extends the service life of the cable chain.
