DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model.

[0023] Please refer to Figures 1-4 The utility model provides a technical scheme:

[0024] Embodiment one: a high-precision chamfering cutter, including handle 1, handle 1 one end fixedly connected with knife head 2, knife head 2 outside is provided with blade 3, and blade 3 is fixedly connected with connecting sleeve 4 inside, handle 1 outside is provided with positioning column 5, and positioning column 5 is fixedly installed on knife head 2 by locking screw 6, and blade 3 is rotatably connected on positioning column 5 by connecting sleeve 4, simultaneously, blade 3 is rotatably connected on knife head 2, and the outer wall of positioning column 5 is fixedly connected with pressing plate 7, and the other end of pressing plate 7 is arranged above blade 3, the inner wall of knife head 2 is fixedly connected with limiting ring 8, and connecting sleeve 4 is rotatably connected below limiting ring 8, and the inner groove 9 is set in knife head 2, and the mounting plate 10 is fixedly connected on the upper portion of inner groove 9, and the threaded rod 11 is rotatably connected between mounting plate 10 and knife head 2, the connecting block 12 is screw-connected on the outer lateral wall of threaded rod 11, the fixed block 14 is fixedly connected on the bottom of connecting block 12, the handle 16 is fixedly connected on the top of threaded rod 11, the limiting plate 13 is fixedly connected on the outer lateral wall of connecting block 12, the limiting groove 15 is set in knife head 2, and limiting plate 13 is slidably connected in limiting groove 15, simultaneously, connecting block 12 is slidably connected in inner groove 9.

[0025] In use of the mechanical equipment, the cutter head 2 is installed on the equipment by the cutter handle 1. When adjustment is needed according to the cutting size of the workpiece, the operation is very simple. Only need to rotate the handle 16 above the mounting plate 10, the handle 16 is rotated to drive the threaded rod 11 to rotate synchronously, and then push the connecting block 12 to move upward along the threaded rod 11. During the movement, the limiting plate 13 plays a limiting role in the limiting groove 15 to ensure that the connecting block 12 always moves stably along a straight line. The upward movement of the connecting block 12 causes the fixed block 14 to separate from the blade 3, at which time the blade 3 can be freely rotated for adjustment. The blade 3 is flexibly rotated on the positioning column 5 through the connecting sleeve 4, and the pressing plate 7 cooperates with the limiting ring 8 to accurately position the blade 3, preventing it from deviating during adjustment. After the blade 3 is adjusted to the appropriate position, the handle 16 is rotated in the opposite direction, the connecting block 12 immediately moves downward, driving the fixed block 14 to re-press the blade 3, and the fixing is completed. At this point, cutting operation can be immediately carried out. Through the close cooperation of these components, the blade 3 is quickly adjusted, greatly improving the work efficiency.

[0026] The working principle is that when the staff needs to use the device for work, the cutter head 2 is installed on the mechanical equipment through the cutter handle 1, and adjustment is needed according to the cutting size of the workpiece. At this time, only need to rotate the handle 16 above the mounting plate 10, which will drive the threaded rod 11 to rotate, thereby driving the connecting block 12 of the outer wall to move upward. The connecting block 12 is limited in the limiting groove 15 by the limiting plate 13 during movement, ensuring that the direction of the connecting block 12 remains consistent during movement. When the connecting block 12 moves upward, the fixed block 14 will be separated from the blade 3, at which time the blade 3 is rotated for adjustment. The blade 3 is rotated on the positioning column 5 through the connecting sleeve 4, and the pressing plate 7 and the limiting ring 8 will position the blade 3. After the blade 3 is adjusted to the appropriate position, the handle 16 is rotated in the opposite direction, causing the connecting block 12 to move downward, and the fixed block 14 is used to fix the blade 3. After the fixing is completed, work can be carried out. Through their cooperation, the blade 3 is quickly adjusted, improving the work efficiency.

[0027] It should be noted that in this text, relationship terms such as first and second are only used to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between the entities or operations.
