[0036] Specifically, the two pipes, namely the coolant delivery pipe 14 and the coolant inlet pipe 16, are respectively used to deliver coolant to the cutting disc and replenish coolant from the storage tank to the pump tank. Check valves 12 are provided on their exteriors to ensure that the coolant can only flow in one direction, prevent backflow, and guarantee the normal operation of the cooling system. The check valves 12 are installed on the coolant delivery pipe 14 and the coolant inlet pipe 16, allowing fluid to pass through in only one direction, preventing the coolant from flowing back, and ensuring that the coolant flows along the designed path.

[0037] Working principle: Place the fixing frame 1 on the cavity wall of the external wall insulation layer and move it to the opening. Start the second motor 22 to drive the worm 23 to rotate, and at the same time drive the worm wheel 27 to rotate. Subsequently, transmit the rotation to the rotating shaft 25 and the gear 26 through the worm wheel 27, and then drive the cutting blade 32 to move to an appropriate height through the rack 29, so as to adjust the depth of the cutting blade 32 cutting into the external wall insulation layer. Subsequently, the third motor 31 drives the cutting blade 32. By making the first roller 21 and the second roller 21 fit with the surface of the cavity wall of the external wall insulation layer, the fixing frame 1 can be quickly moved. By rotating the screw 18, the screw 18 pushes the clamping plate 19 to move under the action of the surface thread, and the clamping width of the fixing frame 1 can be adjusted, so as to be applicable to external wall insulation layers of different thicknesses during use. When cutting operations are carried out, in order to avoid the blade temperature being too high and thus affecting its service life, at this time, open the solenoid valve on the oil delivery pipe 14. The spring 13 will push the piston 11 to move to the left at this time, push out the push rod 9, start the second motor 22 to drive the cam 6 to rotate, the cam 6 pushes the push plate 10 to push the push rod 9 back into the pump box 8, drive the piston 11 to move to the right, and through the cooperation of the two one-way valves 12, the coolant is sucked into the pump box 8 along the oil inlet pipe 16. When the cam 6 and the push plate 10 are not in contact, the spring 13 will push the piston 11 to deliver the coolant along the oil delivery pipe 14 to the nozzle 15 and spray it on the cutting blade 32 to achieve cooling, and then close the solenoid valve.
