Fluid-controlled wire tension mechanism

Abstract

The present invention relates to a fluid-controlled wire tension mechanism including a sealed container, a control valve, and a delivery spool. The sealed container has a space. The control valve is coupled to the sealed container to control fluid pressure in the space. The delivery spool is coupled to the sealed container with a compression end and a reel. The compression end is placed in the space, and the reel is located outside the sealed container to send out a cutting wire. Wherein, a fluid enters the space and applies pressure on the compression end. The present invention utilizes the fluid pressure to produce the rotating impedance to the delivery spool, so that the component is wear-proof, the line tension is easily controlled and the stream of the cutting wire can be stable for a long time. Therefore, the cutting effect and the shape are more precise.
