Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3A lathe tool holder includes a base 1, a tool holder 2 is provided on the top of the base 1, and a locking groove 7 is provided inside the tool holder 2. The tool holder 2 is characterized in that a locking handle 8 is inserted into the locking groove 7, a tool head 3 is provided at one end of the locking handle 8, a cutting edge 4 is provided on one side of the tool head 3, connecting grooves 5 are provided on both sides of the tool holder 2, a locking member 6 is provided inside the connecting groove 5, and a locking groove 9 is provided on the side of the locking handle 8.

[0022] The inner wall of the snap-fit ​​groove 7 fits into the outer wall of the snap handle 8.

[0023] Specifically, the cutting head 3 is inserted into the locking groove 7. During this process, the outer wall of the locking handle 8 is tightly fitted and locked with the inside of the locking groove 7. At this time, the locking groove 9 corresponds to the locking part 6, thereby limiting the locking handle 8 and fixing the cutting head 3. This achieves a fixed locking connection between the cutting handle 2 and the cutting head 3. Furthermore, due to the tight locking method, the cutting head 3 and the cutting handle 2 will not shake during the use of the cutting edge 4 due to the force exerted on the cutting edge 4 during the cutting process.

[0024] according to Figure 4 As shown, the snap-fit ​​component 6 includes a fixed plate 61, a movable post 62 inserted inside the fixed plate 61, a movable plate 63 fixedly mounted at one end of the movable post 62, a snap block 64 fixedly mounted at one end of the movable plate 63, a spring 65 mounted on one side of the movable plate 63, a limit block 66 mounted at one end of the movable post 62, a pull handle 67 mounted at one end of the limit block 66, a threaded rod 68 inserted inside the limit block 66, a threaded sleeve 69 threadedly connected to the outside of the threaded rod 68, and a rotating handle 610 mounted at one end of the threaded sleeve 69.

[0025] The tool holder 2 has mounting grooves on both sides. The inner wall of the mounting groove is fixedly connected to the outer side of the fixing plate 61, and one side of the threaded sleeve 69 is fixedly connected to the side wall of the tool holder 2. The outer side of the movable plate 63 is slidably connected to the inner wall of the mounting groove, and the locking block 64 is engaged with the locking groove 9.

[0026] In use, the engagement of the locking block 64 with the locking groove 9 achieves a fixed engagement between the locking handle 8 and the locking groove 7. By rotating the rotating handle 610, it moves within the threaded sleeve 69 while rotating until one end of the rotating handle 610 engages with the inner wall of the limiting block 66. At this point, the position of the limiting block 66 is fixed, thus fixing the position of the locking block 64. This means that the outer wall of the locking handle 8 and the inner wall of the locking groove 7, as well as the outer wall of the locking block 64 and the inner wall of the locking groove 9, are all tightly engaged. Therefore, when the locking handle 8 is subjected to force, due to the tight engagement, the locking handle 8 cannot... The space for the inner wall of the locking groove 7 to move ensures the stability of the cutter head 3 during use. When the cutter head 3 needs to be disassembled, the handle 610 is rotated in the opposite direction. At this time, the handle 610 is on the inner wall of the threaded sleeve 69. While rotating, it moves until the outer wall of the threaded rod 68 is disengaged from the inner wall of the limiting block 66. At this time, the limiting block 66 is pulled to move the movable plate 63 outward and compress the spring 65 until the locking block 64 is separated from the locking groove 9. Then, the handle 8 is pulled outward to separate the cutter head 3 from the handle 2. The disassembly and installation methods are relatively simple and ensure the locking stability of the cutter head 3 and the handle 2.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
