Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Please refer to Figures 1-4, the present invention provides a technical solution:

A cutting machine for easy fixing and replacement of grinding wheels, comprising a main body 1 and a connecting shaft 2, a connecting shaft 2 is rotatably connected to the top right side of the main body 1, and a screw 8 is fixedly connected to the top of the connecting shaft 2. The outer side of the shaft 2 is fixedly connected with a support block 17, the top of the support block 17 is provided with a grinding wheel 3, the screw sleeve 8 is combined with a sleeve 16, and the left and right sides of the front end surface of the sleeve 16 are rotatably connected with fixed Ring 6, a fixing rod 5 is rotatably connected to the inner side of the bottom end of the fixing ring 6; 13, and the slider 13 is slidably connected with the first chute a, the top of the fixing rod 5 is fixedly connected with a spring 15, and the spring 15 is fixedly connected with the sleeve 16, and the left and right ends of the sleeve 16 are fixedly connected. The limit block 14, the rear end surface of the sleeve 16 is provided with a second chute b, the inner side of the second chute b is slidably connected to the limit rod 11, and the inner side of the left end of the limit rod 11 is rotatably connected with a vertical The shaft 12, the top and bottom outer sides of the vertical shaft 12 are fixedly connected with a horizontally arranged fixing plate 10, the rear end surface of the fixing plate 10 is fixedly connected with a protective shell 4, and the protective shell 4 is fixedly connected with the main body 1, A torsion spring 9 is disposed on the outer side of the vertical shaft 12 , and the upper and lower ends of the torsion spring 9 are respectively fixedly connected to the fixing plate 10 and the limiting rod 11 .

The top end of the screw 8 is fixedly connected with a horizontally arranged blocking block 7, which can limit the sleeve 16 through the action of the blocking block 7 to prevent the sleeve 16 from falling off accidentally. Two, evenly distributed around the sleeve 16, the fixing ring 6 can be limited by the action of the limiting block 14 to prevent the fixing ring 6 from shaking.
