[0020] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model with reference to the drawings and embodiments.

[0021] The lathe turning tool bar has a tool holder 1 and a tool tip 2;

[0022] Embodiment 1: As Figure 1 and Figure 3As shown, one end of the tool handle 1 is provided with a tool tip 2. A sunken tool groove 3 is arranged on the surface of the tool tip 2. A cutting blade 4 is arranged inside the tool groove 3. The cutting blade 4 is fixed in the tool groove 3 by a screw 5 passing through its interior. During the cutting process, the tip of the cutting blade 4 fits against the surface of the workpiece, and the cutting of the workpiece is achieved by rotation. A spacer ring 6 is arranged between the lower surface of the cutting blade 4 and the tool groove 3, and the spacer ring 6 is sleeved outside the screw 5. The spacer ring 6 is used to support the cutting blade 4. Two slidably inserted positioning posts 7 are symmetrically arranged inside the tool groove 3. One side of the positioning post 7 close to the screw 5 is curved, and the side of the positioning post 7 far from the screw 5 is flat. This design helps to accurately position the cutting blade 4 in the tool groove 3;

[0023] As Figure 3 shown, a spring 8 is arranged below the positioning post 7. The positioning post 7 is elastically connected to the tool tip 2 through the spring 8, allowing the positioning post 7 to move up and down inside the tool groove 3 to adapt to cutting blades 4 of different shapes;

[0024] As Figures 1 to 5 shown, the lifting range of the positioning post 7 is limited between the cutting blade 4 and the spacer ring 6, enabling the positioning post 7 to either rise to be level with the cutting blade 4 to limit the cutting blade 4, or descend to be level with the spacer ring 6 to support the cutting blade 4;

[0025] As Figures 1 to 5 shown, screws 9 are arranged on both sides of the tool tip 2. A positioning groove 10 matching the screw 9 is formed on the surface of the positioning post 7. The positioning post 7 lifted to the highest position is fixed by the screw 9, making the positioning post 7 more stable during the limiting process.

[0026] As Figure 1 shown, the cutting blade 4 is square. The top end of the positioning post 7 fits against the bottom of the cutting blade 4. The shape of the cutting blade 4 matches the tool groove 3.

[0027] For the square cutting blade 4, the positioning post 7 is pressed down to be level with the spacer ring 6, so that the top end of the positioning post 7 fits against the bottom of the cutting blade 4. The positioning post 7 and the spacer ring 6 together support the cutting blade 4. Since the shape of the square cutting blade 4 matches the tool groove 3, it can be stably placed in the tool groove 3 to prevent displacement during the cutting process.

[0028] Embodiment 2: As Figure 2 and Figure 3 shown, the cutting blade 4 is diamond-shaped. The positioning posts 7 are arranged on both sides of the cutting blade 4, and the outer wall of the positioning post 7 fits against the side wall of the cutting blade 4.

[0029] When using the diamond-shaped cutting blade 4, the positioning posts 7 will be arranged on both sides of the cutting blade 4, and the outer wall of the positioning post 7 fits against the side wall of the cutting blade 4. The positioning posts 7 are fixed by the screws 9, and the left and right restrictions of the positioning posts 7 are used to cooperate with the tool groove 3 to keep the cutting blade 4 stable.

[0030] Embodiment 3: As Figure 4 and Figure 5 shown, the blade 4 is triangular, the positioning posts 7 are arranged on both sides of the blade 4, and the outer wall of the positioning posts 7 is in contact with the side wall of the blade 4. Embedding grooves 11 are symmetrically formed on the inner wall of the tool groove 3, and both ends of the blade 4 are respectively inserted into the corresponding embedding grooves 11.

[0031] For the triangular blade 4, the positioning posts 7 are also arranged on both sides of the blade 4, and the outer wall of the positioning posts 7 is in contact with the side wall of the blade 4. In addition, embedding grooves 11 are symmetrically formed on the inner wall of the tool groove 3, and both ends of the triangular blade 4 are respectively inserted into the corresponding embedding grooves 11, further enhancing the stability of the blade 4. The left and right restrictions of the positioning posts 7 cooperate with the embedding grooves 11 to maintain the stability of the blade 4.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
