[0015] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0016] like Figure 1 , Figure 2 , Figure 3As shown, this ratchet wrench-type hand-held milling machine for three grooves includes a base 1, on which a processing device 2 and a clamping device 3 are mounted. The base 1 serves as the basic support structure for the entire machine, providing a stable mounting platform for the processing device 2 and the clamping device 3, ensuring that the relative positional accuracy of each component is maintained during operation and reducing the impact of vibration on the processing quality. The clamping device 3 is respectively provided with a base 4, a worktable 5 mounted on the base 4, a feeding assembly 6, a push plate assembly 7, a clamping assembly 8, and a limiting assembly 9 located on the side of the worktable 5. The worktable 5 has a square groove below the clamping assembly 8, in which a processing block 10 for placing a processing wrench is installed. The processing block 10 is used to place the wrench that enters under the clamping block 23 through the push plate 27. A fixing block 11 extends outward from the end of the processing block 10, and a groove 12 is formed on the fixing block 11. Three processing grooves 13 are formed on the fixing block 11, which correspond to the processing grooves 13 on the wrench to provide precision. The precise machining position facilitates machining with the three-layer milling cutter 20. The machining device 2 includes a slide rail seat 14 with a slide rail and a machining seat 15. The slide rail seat 14 is fixed to the machine base 1 with bolts, providing stable support and precise guidance for the machining seat 15. The machining seat 15 is mounted on the slide rail of the slide rail seat 14 and can move linearly on the slide rail to adjust the machining position to meet different machining needs. The machining seat 15 is provided with a fixed seat 16, and the fixed seat 16 contains a circular horizontal machining part 17. A machining shaft 19 is provided inside the horizontal machining part 17, and both ends of the machining shaft 19 extend outward from the horizontal machining part 17. A fixing plate 18 for fixing the machining shaft 19 is provided at one end of the horizontal machining part 17. Three layers of milling cutters 20 are sleeved on one end of the machining shaft 19, and each layer of the three layers of milling cutters 20 corresponds to the opening slot on the fixing block 11. The correspondence between the three layers of milling cutters 20 and the opening slots enables the milling of three slots to be completed simultaneously in one machining process, which greatly improves the machining efficiency.

[0017] To elaborate further, a drive device 21 is provided on the other end of the horizontal machining part 17, and the drive device 21 is connected to the machining shaft 19 via a transmission belt. The drive device 21 is usually an electric motor, which transmits power to the machining shaft 19 via the transmission belt, driving the machining shaft 19 and the milling cutter to rotate at high speed, thereby realizing the milling of the wrench.

[0018] To elaborate further, the processing block 10 is fixedly mounted on the base 4 with bolts, and the bolt connection method facilitates the disassembly and replacement of the processing block 10.

[0019] To elaborate further, the clamping assembly 8 is provided with a clamping seat 22, a clamping block 23, a telescopic rod 24 and a limiting rod 25, and the clamping block 23 is located above the processing block 10. The telescopic rod 24 is provided with a cylinder block 26, which is connected to the clamping seat 22. The cylinder controls the movement of the cylinder block 26 to drive the telescopic rod 24 to extend and retract, thereby realizing the up and down movement of the clamping block 23.

[0020] To elaborate further, the push plate assembly 7 is equipped with a push plate 27 driven by a cylinder. The cylinder serves as a power source, providing linear motion power to the push plate 27, enabling the push plate 27 to push the wrench into the processing position at a predetermined speed and stroke.
