[0006] The tool holder has a mounting hole in the middle. The cylinder, the limiting member and the first bolt are set in the mounting hole. The tool holder also has a fixing hole. A second bolt is set in the fixing hole and is set in the through hole.

[0007] In this tool mounting structure of the present invention, the mounting hole is composed of a first circular hole, a conical hole, and a second circular hole. The first circular hole is provided with symmetrically arranged sliding grooves, and the conical hole is connected to the fixing hole.

[0008] In this tool mounting structure of the present invention, the limiting member consists of a mounting part and symmetrically arranged elastic arms. The front end of the elastic arm is provided with a limiting body, and the tapered hole is provided with a limiting groove that cooperates with the limiting body.

[0009] In this tool mounting structure of the present invention, the limiting groove and the sliding groove are set at 90°.

[0010] In this tool mounting structure of the present invention, a spring is provided between the limiting member and the first bolt, and the spring is sleeved on the first bolt.

[0011] In this tool mounting structure of the present invention, a movable part is also provided on the first bolt. The movable part is sleeved on the first bolt. One end of the spring contacts the limiting part, and the other end contacts the movable part.

[0012] The tool mounting structure of this utility model has the following advantages: The structure is compact and ingeniously designed. In use, the tool is directly inserted under force, then rotated 90 degrees. The limiting body and limiting groove cooperate to achieve one-point limiting of the tool. The tool can also be fixed by a second bolt. These two limiting points ensure stable tool mounting, preventing the tool from falling off due to loose bolts. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figures 1 to 6 As shown, this utility model's lathe tool mounting structure includes a lathe tool 1 and a tool holder 2, with the lathe tool 1 mounted on the tool holder 2. During installation, the lathe tool 1 is directly inserted into the tool holder 2, then rotated 90°, and finally secured with a second bolt 9.

[0021] The cutting tool 1 has a cylinder 3, a through hole 4, and a limiting member 5. The limiting member 5 is installed on the cylinder 3 by a first bolt 6.

[0022] Meanwhile, a mounting hole 7 is provided in the middle of the tool holder 2, and the cylinder 3, the limiting member 5, and the first bolt 6 are arranged in the mounting hole 7. The tool holder 2 is also provided with a fixing hole 8, in which a second bolt 9 is provided, and the second bolt 9 is arranged in the through hole 4.

[0023] The mounting hole 7 consists of a first circular hole 10, a tapered hole 11, and a second circular hole 12. The first circular hole 10 is located outside the mounting hole 7, and the second circular hole 12 is located inside the mounting hole 7. The tapered hole 11 connects the first circular hole 10 and the second circular hole 12. A symmetrically arranged sliding groove 13 is provided in the first circular hole 10. The tapered hole 11 communicates with the fixing hole 8, and the sliding groove 13 cooperates with the elastic arm 14 on the limiting member 5.

[0024] The limiting member 5 consists of a mounting part 15 and symmetrically arranged elastic arms 14. A limiting body 16 is provided at the front end of each elastic arm 14, and a limiting groove 17 that mates with the limiting body 16 is provided within the tapered hole 11. The limiting groove 17 is set at a 90° angle to the sliding groove 13. The mounting part 15 is provided with a through hole 19 that mates with the connecting rod 18. The elastic arm 14 has a certain degree of elasticity and can deform under force.

[0025] A spring 20 is provided between the limiting member 5 and the first bolt 6, and the spring 20 is sleeved on the first bolt 6. The spring 20 can push the movable member 21 so that the movable member 21 can contact the blocking plate 22.

[0026] A movable part 21 is also provided on the first bolt 6. The movable part 21 is fitted on the first bolt 6. One end of the spring 20 is in contact with the limiting part 5, and the other end is in contact with the movable part 21.
