[0062] Reference Figure 1 , Figure 2 and Figure 3As shown, the figure shows a multifunctional chamfering tool holder 100 which is easy to adjust, including a support 1, a travel hole 2 is opened at the front end of the support 1, and the inner diameter of the travel hole 2 is slidably connected with an extended mounting tube 3, and a mounting port 4 is opened at the front end of the extended mounting tube 3, and travel columns 5 are fixedly connected to both sides of the extended mounting tube 3, and the end of the travel column 5 away from the extended mounting tube 3 is fixedly connected to a support rod 6, and a connecting rod 7 is installed on the top of the support rod 6, and both sides of the bottom of the connecting rod 7 are fixedly connected to the top of the support rod 6, and a first through hole 8 is opened on the surface of the connecting rod 7, and the inner diameter of the first through hole 8 is slidably connected to a limiting rod 9, and a limiting groove 10 is opened on the surface of the top of the support 1, and the inner diameter of the limiting groove 10 is plugged into the surface of the limiting rod 9, so as to limit The top of the positioning rod 9 is fixedly connected with a first limit plate 11. After the user installs the tool into the inside of the mounting port 4, the user drives the limit rod 9 by moving the first limit plate 11 upward, so that the limit rod 9 moves upward and disengages from the inner diameter of the limit groove 10, thereby releasing the limit on the extended mounting tube 3. The user adjusts the position of the tool by moving the extended mounting tube 3. When the position of the tool is adjusted to a suitable position, the limit rod 9 is driven downward by the first limit plate 11, so that the surface of the limit rod 9 is plugged into the inner diameter of the limit groove 10, thereby fixing the position of the extended mounting tube 3, thereby completing the adjustment of the tool position, so that the user can process over-specification workpieces and improve the overall flexibility.

[0063] Reference Figure 2 and Figure 3 As shown, the number of the limiting grooves 10 is several and evenly distributed on the surface of the top of the support 1, and the limiting grooves 10 are adapted to the limiting rod 9. Through the coordinated use of the limiting grooves 10 and the limiting rod 9, the user can make various adjustments according to needs, thereby improving the overall compatibility of the device. The top of the connecting rod 7 is fixedly connected with a first spring 12, and the top of the first spring 12 is fixedly connected to the bottom of the first limiting plate 11, and the inner diameter of the first spring 12 is slidably connected to the surface of the limiting rod 9. When the first limiting plate 11 drives the limiting rod 9 to move upward, the first spring 12 is simultaneously charged, and when the position of the tool After the adjustment is completed, the first limit plate 11 is loosened and the rebound force released by the first spring 12 drives the first limit plate 11 to quickly insert the limit rod 9 into the inner diameter of the limit groove 10 to fix the position of the extended mounting tube 3. The surfaces on both sides of the support 1 are provided with travel grooves 13, and the inner diameter of the travel groove 13 is slidingly connected to the surface of the travel column 5. When the extended mounting tube 3 moves, the sliding connection between the surface of the travel column 5 and the inner diameter of the travel groove 13 is used to limit the movement of the extended mounting tube 3, thereby preventing the extended mounting tube 3 from being offset and preventing the extended mounting tube 3 from being separated from the inner diameter of the travel hole 2.

[0064] Reference Figure 4 and Figure 5As shown, a fixing hole 14 is provided on the surface of the limiting rod 9, and a fixing rod 15 is slidably connected to the inner diameter of the fixing hole 14. A protrusion 16 is fixedly connected to the rear end of the connecting rod 7. A second through hole 17 is provided on the surface of the protrusion 16. The inner diameter of the second through hole 17 is slidably connected to the surface of the fixing rod 15. A second limiting plate 18 is fixedly connected to the rear end of the fixing rod 15. When the limiting rod 9 is inserted into the inner diameter of the limiting groove 10, the fixing rod 15 is driven by the second limiting plate 18 to be inserted into the inner diameter of the fixing hole 14, so that the position of the limiting rod 9 is fixed, thereby preventing The limiting rod 9 moves due to vibration, which causes the limiting rod 9 to disengage from the inner diameter of the limiting groove 10, causing the tool to be displaced during processing. The rear end of the protrusion 16 is fixedly connected to the second spring 19, and the rear end of the second spring 19 is fixedly connected to the front end of the second limiting plate 18. The inner diameter of the second spring 19 is slidably connected to the surface of the fixing rod 15. When the fixing rod 15 is inserted into the inner diameter of the fixing hole 14, the tension of the second spring 19 limits the second limiting plate 18 to prevent the fixing rod 15 from disengaging from the inner diameter of the fixing hole 14.

[0065] As an implementation mode, after the user installs the tool into the installation port 4, the user can drive the limiting rod 9 by moving the first limiting plate 11 upwards, so that the limiting rod 9 moves upwards and disengages from the inner diameter of the limiting groove 10, thereby releasing the limit on the extended installation cylinder 3. When the first limiting plate 11 drives the limiting rod 9 to move upwards, the first spring 12 accumulates force at the same time, and the user adjusts the position of the tool by moving the extended installation cylinder 3. When the extended installation cylinder 3 moves, the sliding connection between the surface of the stroke column 5 and the inner diameter of the stroke groove 13 is used to adjust the movement of the extended installation cylinder 3. It plays a limiting role, preventing the extended mounting tube 3 from being offset and preventing the extended mounting tube 3 from being separated from the inner diameter of the stroke hole 2. When the position of the tool is adjusted to a suitable position, the first limit plate 11 is released, and the rebound force released by the first spring 12 drives the first limit plate 11 to quickly insert the limit rod 9 into the inner diameter of the limit groove 10 to fix the position of the extended mounting tube 3, thereby completing the adjustment of the tool position. Through the coordinated use of the limit groove 10 and the limit rod 9, the user can make various adjustments according to needs, thereby improving the overall compatibility of the chamfering tool holder 100.
