The fixing ring 16 is threadedly connected to a fixing screw 17 for tightening and fixing the outer side of the guide nozzle body 2 inward.

[0020] Please see Figure 2-6 This utility model provides a technical solution: a simple and quick installation through-type guide nozzle device, including a mounting housing 1, a guide nozzle body 2 movably inserted into the mounting hole on the side of the mounting housing 1, and annular guide nozzle grooves 3 respectively opened on the outer sides of the front and rear ends of the guide nozzle body 2 outside the mounting housing 1. A fixing block 4 is fixedly installed on the side of the mounting housing 1 above the guide nozzle body 2. A threaded rod 6 is threadedly connected to the threaded hole 5 on the front side of the fixing block 4. The threaded rod 6 is easily installed by rotating in the threaded hole 5 on the fixing block 4, and it is also easy to twist the handle assembly 9. A handle assembly 9 with a triangular cone bottom is fixedly installed on the outer side of the threaded rod 6. A bevel at the bottom end of the handle assembly 9 contacts and presses down on the bottom of the inner wall of the guide nozzle groove 3. By engaging and disengaging the twistable handle assembly 9 with the guide nozzle groove 3, the installation and replacement of the guide nozzle body 2 are facilitated.

[0021] Furthermore, such as Figure 6 As shown, the chuck assembly 9 includes a chuck 91, a handle 92, a slot 93, and a plug 94. The bottom end of the chuck 91 is a triangular cone.
