[0021] The following is combined Figures 1 to 3 This describes a highly practical blade-opening head according to an embodiment of the present invention.

[0022] A highly practical blade unfolding head includes a blade unfolding base 1, a movable base 2, a driving component 3, a nut 4, and a spring clamp 5. The movable base 2 is movably installed at one end of the blade unfolding base 1. A mounting block 21 protrudes from the outer side of the movable base 2. The spring clamp 5 is disposed inside the mounting block 21. The nut 4 is fitted onto the mounting block 21 and fixes the position of the spring clamp 5. The driving component 3 is installed inside the blade unfolding base 1 and pushes the movable base 2 to move back and forth.

[0023] A highly practical tool-unfolding head is used to clamp tools for machining workpieces. The tool is mounted at the spring chuck 5 and fixed in place by turning the nut 4. Tool mounting can be achieved using only the tool-unfolding base 1, the moving base 2, the drive component 3, the nut 4, and the spring chuck 5, making disassembly, assembly, and maintenance simple.

[0024] The movable seat 2 is movably installed at one end of the blade holder 1. The driving component 3 pushes the movable seat 2 to move back and forth, enabling the movable seat 2 to drive the blade to move and cut the workpiece.

[0025] Specifically, a rack 22 is provided on one side of the movable seat 2 inside the tool holder 1; the driving component 3 includes a first gear 31 and a gear shaft 32, with the first gear 31 meshing with the rack 22; one end of the gear shaft 32 meshes with the first gear 31, and the other end of the gear shaft 32 extends out of the outside of the tool holder 1. The back-and-forth movement of the gear shaft 32 drives the first gear 31 to rotate, which in turn drives the movable seat 2 to move through the rack 22. By using the gear shaft 32 to drive the first gear 31 to rotate, and the first gear 31 then pushes the rack 22 to move the position of the movable seat 2, a large driving force and high precision can be achieved, ensuring the accuracy of the processed workpiece.

[0026] Specifically, the blade holder 1 has inclined grooves 11 on both sides of the end where the movable base 2 is mounted, and inclined blocks are provided on both sides of the movable base 2. The inclined blocks are slidably mounted in the inclined grooves 11, which facilitates the movement of the movable base 2.

[0027] To further clarify, nut 4 is an ER32 nut. It is suitable for mounting internal turning tools and is beneficial for machining internal grooves.

[0028] Specifically, the cutting tool is installed inside the spring chuck 5. The tool holder 1 is cylindrical, facilitating the installation of the drive unit 3.

[0029] Specifically, the blade holder 1 is equipped with a second gear 6, which is mounted on both sides of the gear shaft 32 along with the first gear 31. The second gear 6 meshes with the gear shaft 32. This helps to stabilize the gear shaft 32 during movement and prevents it from shaking.

[0030] Other components and operations of the practically applicable blade-opening head according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
