DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a high-strength CNC tool comprises a tool head 1 and a tool handle 2, wherein a tool rod 3 is provided at the top of the tool head 1, and the tool head 1 is connected to the tool handle 2 through the tool rod 3, and two groups of relatively parallel blocks 4 are provided on the upper outer side of the tool rod 3; a bottom plate 5 is fixedly connected to the inner side of the tool handle 2, and a spring 11 and a movable part 7 are equidistantly connected to the inner side of the bottom plate 5, and an arc-shaped splint 6 is connected to the inner side of the spring 11 and the movable part 7, and the movable part 7 is located in the middle of the inner side of the arc-shaped splint 6 and the bottom plate 5, and rubber anti-slip teeth 12 are provided on the inner side of the arc-shaped splint 6.

[0024] A pressure plate 19 is provided inside the tool handle 2 and above the base plate 5. The inner wall of the base plate 5 is connected to two sets of parallel screw sleeves 16 through bearings. A worm wheel 13 is welded to the top of the screw sleeve 16. A threaded rod 15 is welded to the top of the pressure plate 19. The top of the threaded rod 15 is connected to the screw sleeve 16 through threads. A cavity 18 is provided inside the tool handle 2. A worm 14 is connected to the inner wall of the cavity 18 through a bearing. The worm 14 is meshed with the worm wheel 13. One end of the worm 14 extends to the outside of the tool handle 2 and is welded to a knob 17.

[0025] The movable part 7 includes a movable tube 8, the inner side of which is clamped with a piston head 9 and a movable rod 10, one end of the piston head 9 is connected to one end of the movable rod 10; the other end of the movable rod 10 is connected to the arc-shaped clamping plate 6, and one end of the movable tube 8 is connected to the inner side of the bottom plate 5.

[0026] The inside of the knife handle 2 is provided with a limiting groove that cooperates with the blocking block 4, and the limiting groove includes a first limiting groove 20, a second limiting groove 21 and a locking limiting groove 22; the first limiting groove 20 is arranged along the vertical direction of the adjacent base plate 5, and the second limiting groove 21 is located between the base plate 5 and the pressure plate 19; the locking limiting groove 22 is arranged at the vertical extension of the second limiting groove 21 in the retraction direction.

[0027] It should be noted that the utility model is a high-strength CNC tool. First, the tool rod 3 is inserted into the tool handle 2. At this time, the clamping block 4 can move upward along the first linear groove 20, and then rotate along the second limiting groove 21, and can be stuck in the locking limiting groove 22 after retracting to prevent it from extending out. By rotating the knob 17, the knob 17 drives the worm 14 to rotate, so that the worm 14 drives the worm wheel 13 to rotate, and the rotation of the worm wheel 13 drives the screw sleeve 16 to rotate, so that the screw sleeve 16 presses the pressure plate 19 downward through the threaded rod 15 when rotating, so that the clamping block 4 is limited; when the tool is in use, the rubber anti-skid teeth 12 effectively prevent the tool rod 3 from sliding, and the tool rod 3 shakes and squeezes the arc clamping plate 6, and the arc clamping plate 6 squeezes the spring 11 and the movable part 7. Under the action of the spring 11 and the movable part 7, it can not only better fit the shape of the tool rod 3, but also effectively reduce the impact on the tool head 1 during use, enhance the tool stability, and thus enhance the high strength of the tool during use.
