[0020] The present invention will be further described below with reference to the embodiments.

[0021] See also Figure 1-4 The utility model provides a tool for deep groove processing of castings, including a tool column 1 and a tool head. The tool head is fixed at the bottom end of the tool column 1. A clamping seat 2 is fixed on both sides of the tool column 1. A tool head sleeve 3 is provided on the outer movable sleeve of the tool head. The inner diameter of the tool head sleeve 3 is larger than the diameter of the tool head. A ring block 14 is fixed on the top of the tool head sleeve 3. Two insertion rods 10 are fixed on the top of the ring block 14. The insertion rods 10 and the clamping seat 2 are plugged in. Two movable grooves 11 are symmetrically provided inside the clamping seat 2. The movable groove 11 of the clamping seat 2 is internally slidably connected to a limit rod 4. The limit rod 4 is inserted into the insertion rod 10. The lower end of one side of the limit rod 4 is rounded. Angle processing; a moving block 12 is fixed to the outer side of the limiting rod 4 corresponding to the movable groove 11, and a spring 13 is provided on the outer side of the limiting rod 4. One end of the spring 13 is fixed to the moving block 12, and the other end of the spring 13 is fixed to the inner wall of the movable groove 11. By inserting the insertion rod 10 on the cutter head cover 3 into the holder 2, the limiting rod 4 is inserted into the insertion rod 10 under the elastic force of the spring 13, and the insertion rod 10 is limited, so that the cutter head is protected by the cutter head cover 3 and the contamination of impurities is reduced; a stretching mechanism is provided at one end of the limiting rod 4 extending out of the holder 2, which facilitates the extension and retraction of the limiting rod 4.

[0022] Further as Figure 2 and Figure 3 As shown, it is worth explaining in detail that the stretching mechanism includes a connecting rope 8 fixed at one end of the limit rod 4, the two limit rods 4 are connected by the connecting rope 8, support blocks 6 are fixed on both sides of the base 2, and a ring 7 is fixed at one end of the support block 6. The connecting rope 8 passes through the ring 7, and by pulling the connecting rope 8 upward, the limit rod 4 is pulled to move to both sides respectively, which facilitates the limit rod 4 to disengage from the insertion rod 10, and the connecting rope 8 is limited by the ring 7.

[0023] This solution has the following working process: when the tool is not in use, the tool is exposed to the outside world, making the tool susceptible to contamination by dust and impurities, and also susceptible to corrosion by stains, which will greatly reduce the accuracy of the tool during deep groove processing, thereby affecting processing efficiency. By inserting the insertion rod 10 on the tool head cover 3 into the holder 2, the limit rod 4 is inserted into the insertion rod 10 under the elastic force of the spring 13 to limit the insertion rod 10, thereby protecting the tool head through the tool head cover 3 and reducing contamination by impurities. When the tool head needs to be used, the connecting rope 8 is pulled upward, and the connecting rope 8 slides in the ring 7. The limit rod 4 moves outward under the tension of the connecting rope 8, so that the limit rod 4 disengages from the insertion rod 10, thereby pulling the tool head cover 3 downward, driving the insertion rod 10 to disengage from the holder 2, thereby facilitating the tool head to perform drilling work, and limiting the connecting rope 8 by the ring 7.

[0024] According to the above working process, it can be known that: by inserting the insertion rod 10 on the blade cover 3 into the holder 2, the limiting rod 4 is inserted into the insertion rod 10 under the elastic force of the spring 13, and the insertion rod 10 is limited, which is beneficial for the blade cover 3 to protect the blade and reduce the contamination of impurities. By pulling the connecting rope 8 upward, the connecting rope 8 slides in the ring 7, and the limiting rod 4 moves outward under the tension of the connecting rope 8, so that the limiting rod 4 is disengaged from the insertion rod 10, thereby pulling the blade cover 3 downward, driving the insertion rod 10 to disengage from the holder 2, which is beneficial for the disassembly and assembly of the blade cover 3 when the blade needs to be used, thereby improving the convenience of operation.

[0025] Further as Figure 2 and Figure 3 As shown, it is worth mentioning that connecting blocks 17 are fixed on both sides of the card seat 2, and the side of the connecting blocks 17 away from each other is rotatably connected to the transmission roller 5, and the connecting rope 8 and the transmission roller 5 are rotatably connected. When the connecting rope 8 is stretched and moved, the connecting rope 8 slides on the transmission roller 5, reducing the friction force of the connecting rope 8 when it is stretched; a rubber hand lever 9 is fixed on the outside of the connecting rope 8, and the rubber hand lever 9 is located at the upper end of the card seat 2. The rubber hand lever 9 improves the comfort when the connecting rope 8 is pulled upward.

[0026] Further as Figure 4 As shown, it is worth mentioning that two fixed shafts 15 are fixed to the lower end of the outer side of the blade cover 3, and the outer side of the fixed shaft 15 is rotatably connected to a grip ring 16. The grip ring 16 is U-shaped, and the outer fixed sleeve of the grip ring 16 is provided with a rubber sleeve. The grip ring 16 facilitates the movement of the blade cover 3 and improves the convenience of carrying. The rubber sleeve increases the friction on the surface of the grip ring 16.

By pulling the upward pulling connecting rope 8, the connecting rope 8 slides in the ring 7, the limiting rod 4 moves outward under the stretching of the connecting rope 8, so that the limiting rod 4 is separated from the insertion rod 10, thereby pulling down the tool head cover 3 and driving the insertion rod 10 to separate from the card seat 2, thereby facilitating the disassembly of the tool head cover 3 when the tool head needs to be used, improving the convenience of operation. When the connecting rope 8 moves in stretching, the connecting rope 8 slides on the transmission roller 5, reducing the friction when the connecting rope 8 stretches, the rubber hand rod 9 improves the comfort when the connecting rope 8 is pulled upward, the grip ring 16 facilitates the movement of the tool head cover 3, improves the convenience of carrying, and the rubber sleeve increases the friction force of the surface of the grip ring 16.
