[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] In existing technology, when a cutting tool is in operation, the toolholder needs to transmit the torque from the power source to the cutter head to achieve cutting processing on the workpiece. Due to the docking method between the cutter head and the toolholder, existing tool structures make it difficult to achieve uniform and stable torque transmission during the torque transmission process. Furthermore, the torque transmission efficiency of traditional tools is low. During the process of torque transmission from the toolholder to the cutter head, some torque is lost at the docking point, converting into heat or other forms of energy loss.

[0004] It should be noted that the above technical background is merely for the purpose of providing a clear and complete description of the technical solutions of the present invention and to facilitate understanding by those skilled in the art. It should not be assumed that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present invention.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] It should be noted that, in the description of this utility model, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise specified, "plurality" means two or more.

[0026] like Figure 1-8 As shown, the utility model provides a quick-connectable cutting tool, comprising a handle 2 and a cutting head 1 mounted at the end of the handle 2. Of the two end surfaces of the handle 2 where the cutting head 1 meets, one end surface is provided with two oppositely disposed arcuate petals 13, with two grooves 14 between the two arcuate petals 13, and the other end surface is provided with two latching protrusions 23 that match the grooves 14, the latching protrusions 23 being inserted into the grooves 14. In a preferred embodiment, the two arcuate petals 13 are formed by a circular ring with two grooves 14 axially cut out, and the two grooves 14 are radially symmetrical. The two arcuate petals 13, when connected to the two latching protrusions 23 inserted into the grooves 14, form a circular ring. The arcuate petals 13 and the latching protrusions 23 are tightly fitted together, effectively preventing displacement and loosening of the connection portion even under high-speed, high-torque conditions, allowing torque to be evenly and stably transmitted from the handle 2 to the cutting head 1.

[0027] The tool also includes a screw 4, the cutter head 1 is axially provided with a through hole 15, the head of the cutter head 1 is also provided with a countersunk hole 16, the countersunk hole 16 is connected to the channel and is coaxially arranged, the butt end of the tool handle 2 is axially provided with a screw hole 21, the screw 4 includes a screw head 43 and a rod 42, the rod 42 includes a threaded portion 41, the rod 42 passes through the through hole 15, the threaded portion 41 of the rod 42 is threadedly connected to the screw hole 21, a screw hole 44 is provided on the end face of the screw head 43, the screw head 43 is located in the countersunk hole 16, and the screw hole 44 is used to be inserted and tightened by an external tool.

[0028] The cutter head 1 comprises a cutter head body 11. The connecting end of the cutter head body 11 is provided with an axially protruding conical boss 12. The arcuate petal 13 is disposed on the end surface of the conical boss 12. The connecting end surface of the shank 2 is provided with an axially protruding first boss 22. The locking protrusion 23 is disposed on the end surface of the first boss 22. The cutter head also comprises a collar 3. One end of the collar 3 is sleeved onto and welded to the first boss 22, while the other end of the collar 3 sleeves onto the outside of the conical boss 12. The center hole of the collar 3 comprises a conical section and a cylindrical section. The conical section mates with the conical boss 12, allowing it to be inserted. When the screw 4 secures the cutter head 1 to the shank 2, the end surface of the collar 3 that abuts the cutter head 1 abuts against the end surface of the cutter head body 11. This conical structure provides positioning and guidance during installation. When the cutter head 1 and the tool handle 2 are docked, the conical boss 12 can be inserted into the conical section of the collar 3, so that the cutter head 1 and the tool handle 2 can remain coaxial during the initial docking, thereby improving the accuracy and efficiency of assembly.
