DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-6 The utility model provides a technical solution: a light guide rod cutting device that is convenient for adjusting the cutting angle, comprising: a cutting table 1, a motor frame 2, a rotating rod 3, a first gear 4, a second gear 5, a connecting rod 6, a cutting motor 7, a cutting blade 8, a connecting column 9, a limiting ring 10, a pull rod 11, a spring 12, a baffle 13, a first threaded rod 14, a limiting column 15, a fixed claw 16, a moving claw 17, a connecting frame 18, a second threaded rod 19 and an electric telescopic rod 20;

[0030] When using the light guide rod cutting device that is easy to adjust the cutting angle, Figure 1 and Figure 2As shown, the first threaded rod 14 is rotated. Since the first threaded rod 14 is rotatably connected to the baffle 13 and the first threaded rod 14 is threadedly connected to the cutting table 1, the rotation of the first threaded rod 14 will make the right side of the baffle 13 away from the left side of the cutting table 1. At this time, the limit column 15 extends from the inside of the cutting table 1. A scale is provided on the outside of the front limit column 15. The distance between the right side of the baffle 13 and the left side of the cutting table 1 can be observed from the scale. Since the distance between the left side of the cutting table 1 and the cutting blade 8 is constant, the cutting length of the light guide rod is determined.

[0031] like Figure 1 and Figure 4 As shown, the second threaded rod 19 is rotated, the second threaded rod 19 is threadedly connected to the cutting table 1, and the second threaded rod 19 is rotatably connected to the connecting frame 18, and the connecting frame 18 is connected to the card slot of the cutting table 1, and the rear side of the connecting frame 18 is fixedly connected to the moving claw 17, and the lower side of the moving claw 17 is tightly fitted with the upper side of the cutting table 1. Rotating the second threaded rod 19 can allow the connecting frame 18 to move backward under the limit of the cutting table 1 until the fixed claw 16 and the moving claw 17 clamp the light guide rod placed above the cutting table 1. In addition, the inner sides of the fixed claw 16 and the moving claw 17 are fixedly connected with rubber pads, which can prevent the light guide rod from shifting during cutting, thereby causing the cutting section to be not horizontal, affecting the cutting effect, and the fixed claw 16 and the moving claw 17 are distributed in an array, which can firmly fix the light guide rod in the middle of the fixed claw 16 and the moving claw 17;

[0032] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, the pull rod 11 is pulled down, and the spring 12 between the connecting column 9 and the pull rod 11 is elastically deformed at this time, and the rotating rod 3 connected to the motor frame 2 is rotated. The rotation of the rotating rod 3 will rotate with the first gear 4, and then the first gear 4 will rotate with the second gear 5 meshing with it. The second gear 5 is fixedly connected to the upper side of the connecting rod 6, and the lower side of the connecting rod 6 is fixedly connected to the cutting motor 7. The connecting rod 6 and the motor frame 2 are also connected in a rotating manner. When the second gear 5 rotates, it will rotate with the cutting motor 7, so that the cutting blade 8 fixedly connected to the left side of the cutting motor 7 is offset, so that the cutting angle can be adjusted. In addition, the lower side of the second gear 5 is arrayed with grooves. When the angle is adjusted, release the pull rod 11. , the spring 12 restores its elastic deformation, pushing the pull rod 11 upward, so that the top of the pull rod 11 is inserted into the groove on the lower side of the second gear 5, and a limit ring 10 is arranged inside the connecting column 9, and the limit ring 10 limits the pull rod 11. The vibration generated by the cutting motor 7 during rotation will not cause the cutting motor 7 to deviate, thereby ensuring the accuracy of the cutting angle. Then start the cutting motor 7 and the electric telescopic rod 20, and the cutting motor 7 will rotate with the cutting blade 8, so that the light guide rod can be cut. The electric telescopic rod 20 will push the motor frame 2 to move backward, and cut the light guide rod into a cross-section at a certain angle. In addition, a slag discharge port is opened inside the cutting table 1, and the cut slag will fall into the collection box through the slag discharge port, thereby keeping the working environment clean and tidy.
