[0033] This embodiment provides a simple ultrasonic knife rod spraying PTFE device, such as Figure 1 As shown in FIG4 , it comprises an outer tube 1, one end of which is detachably connected to a first plug 3, the first plug 3 is in the shape of a cylinder cover, an end surface of the first plug 3 is provided with an end surface opening 301, and the other end of the outer tube 1 is connected to a second plug 2;

[0034] The outer tube 1 is sleeved on the outside of the blade body 401 of the ultrasonic blade rod 4. The blade body 401 of the ultrasonic blade rod 4 is connected to the blade head 402 of the ultrasonic blade rod 4 through a transition section 403. The blade head 402 passes through the end face opening 301 from the inner cavity of the outer tube 1 to the outside of the outer tube 1. The blade head 402 extending to the outside of the first plug 3 is the part of the ultrasonic blade rod 4 that needs to be sprayed with polytetrafluoroethylene.

[0035] Furthermore, the diameter of the end opening 301 is larger than the diameter of the cutter head 402 and smaller than the diameter of the shank body 401 , so that only the cutter head 402 extends from the end opening 301 and the shank body 401 remains in the outer tube 1 , thereby preventing the shank body 401 from being sprayed with PTFE.

[0036] In this embodiment, the second plug 2 is fixedly connected to the outer tube 1 by welding;

[0037] In order to ensure that the length of the cutter head 402 extending out of the first plug 3 does not vary due to external forces or other factors; a spring 5 is arranged in the outer tube 1, one end of the spring 5 is against the second plug 2, and the other end of the spring 5 is against the cutter rod body 401. Under the thrust of the spring 5, the transition section 403 is against the inner edge of the end face opening 301 of the first plug 3, ensuring that the cutter head 402 is fully extended out of the end face opening 301, so that the areas of the ultrasonic cutter rods 4 sequentially installed in the outer tube 1 are consistent in the spraying of tetrafluoro. In addition, under the thrust of the spring 5, the transition section 403 of the ultrasonic cutter rod 4 and the end face opening 301 of the first plug 3 are closely matched and seamlessly connected, so that when the tetrafluoro is sprayed, the tetrafluoro does not penetrate into the cutter rod body 401 of the ultrasonic cutter rod 4.

Under the thrust of the spring 5, the transition section 403 of the ultrasonic knife rod 4 abuts against the inner edge of the end face opening 301 of the first plug 3, and the buckle 101 clamps the buckle slot 302 of the first plug 3; then the knife head 402 on the ultrasonic knife rod 4 extending out of the first plug 3 is sprayed with polytetrafluoroethylene.

[0042] In order to spray polytetrafluoroethylene on multiple ultrasonic knife rods 4 at the same time, the utility model further includes a slide groove 6, the second plug 2 extends outside the outer tube 1, and the outer diameter of the part of the second plug 2 outside the outer tube 1 is greater than the diameter of the outer tube 1, and the outer diameter of the part of the second plug 2 outside the outer tube 1 is also greater than the slot diameter of the slide groove 6, and the second plug 2 is slidably connected with the slide groove 6.
