As diamond cutting wire technology has matured, the use of wire saws has become increasingly popular. These tools typically have a belt drive mechanism in addition to the direct drive to rotate the cutting tool. Such as band saws, circular saws and chain saws and wire saws, require a tensioning support mechanism to achieve effective power transmission, as does belt driven circuit equipment.
The applicant has developed an electric cutting machine system (hand-held power tool) comprising a rotatable spindle with a protective cover, with a start-stop switch, a diverter switch and an interlocking double sided handle for mounting a wire saw wheel, a drive for driving the wire wheel, the drive itself comprising a power take-off system, i.e. a drive motor, a spindle mountable to the wire wheel, a flange for connecting the motor and the transmission of the spindle. To ensure the working efficiency of the wire saw and due to the high load of the cutting, an efficient tensioning support system is needed to tension the wire saw.
In the tensioning method in the prior art, one end of the tool is pulled by rotating a bolt, for example, a hacksaw is adopted, and a hand saw commonly used by a woodworker is used for tensioning a saw blade by tightening handles at two ends of an I-shaped saw frame through a rope. These are obviously difficult to apply for high-load cutting tools and high-power mechanical transmission, and the effect and efficiency are difficult to meet the requirements.

The utility model can not only pre-compress the spring and pre-tighten the driving belt by the pinch roller so as to ensure that the pinch roller is stably contacted with the driving belt, but also avoid the condition that the pinch roller is not installed in place due to manufacturing errors and installation errors; meanwhile, the pinch roller can be always contacted with the driving belt based on the spring, so that the pinch roller is prevented from shaking, and the driving belt is kept to run stably. Such automatic tensioners for drive mechanisms are used on conveyor belts, and there are still drawbacks and shortcomings in the high power mechanical drive for high load cutting tools and the like.
