Specific embodiment
Please refer to Fig. 1~3, in the utility model embodiment, a kind of saw blade adjusting lock nut, including shell 1, shell
1 rear side offers notch, and notch is in linear type, it can be fastened and be dismantled by screwdriver.
The upper surface of shell 1 is fixedly connected with handle 5, and the front surface of shell 1 and is located at center position insertion setting
There is the first thread groove 9, the front surface of shell 1 and is located at the outer ring position of the first thread groove 9 and offers spring groove 7, the first spiral shell
The inside of groove 9 offers internal screw thread 8, and spring groove 7 is internally provided with spring 6, due to the characteristic that screw thread has, so that nut
It is easy to rotate along the direction of helical after tightening, so as to cause nut loosening, spring 6 has pretension, generates after fastening anti-
Elastic force, and under the effect of friction, nut would not loosen, and increase stability, additionally, due to the tension of spring 6,
Certain booster action can be also played in disassembly, improves dismounting speed, so that disassembly is more convenient.
The two sides of handle 5 are provided with sliding rail 2, and the upper surface insertion of handle 5 is provided with the second thread groove 10, handle 5
