Example 1
As shown in fig. 1-3, the present utility model provides a bone saw with a cooling system, comprising a ball bearing 1, a water jet 2 and a bone saw 3; be equipped with on the bone saw 3 with the bearing bracket of ball bearing 1 looks adaptation, ball bearing 1 pass through the bearing bracket with bone saw 3 articulates, water jet 2 by direct welding in on the ball bearing 1, the two relatively fixed, water jet department spun moisture can directly drench the work part of bone saw bit, reduces the temperature of operation part, and through stirring the direction of ball bearing 1 steerable water jet to this multi-angle cooling to the bone saw has been realized, easy operation, convenient to use.
Example 2
The embodiment is further provided with a conduit and a peristaltic pump on the basis of embodiment 1, the conduit 4 is installed at the water inlet of the water nozzle 2, the peristaltic pump 5 is clamped and fixedly installed on the conduit 4, the conduit 4 is continuously extruded forwards by the peristaltic pump 5, a larger pressure is formed on the water flow in the conduit 4, the water flow is further pushed to move forwards, and finally the water is sprayed out from the water spraying port of the water nozzle 2.
Example 3
