In the above description, as a preferred scheme, the main frame includes a circular frame and a rod frame, wherein one end of the circular frame and one end of the rod frame are both provided with internal threads, the other end of the circular frame and the other end of the rod frame are both provided with external threads matched with the internal threads, and the circular frame and the rod frame are screwed and fixed with each other.

In the above description, as a preferable scheme, a welding area is formed at a welding position between the positioning hole and the bottom of the insertion tube, and the welding area is polished.

The utility model discloses produced beneficial effect as follows: welding structure of interior horn type intubate and body frame, including the body frame, set up intubate and the fibre pole in the body frame, the side at the body frame is hugged closely to the fibre pole and installs, ensures that welded structure is complete. The top of body frame is equipped with the pilot hole that switches on with the top of intubate, and the top of intubate is equipped with the inserted hole, and the border of inserted hole carries out tangent connection with the border of pilot hole, and the bottom of body frame is equipped with the locating hole, and the bottom embedding locating hole of intubate carries out welded fastening with the locating hole. Welding after punching from the bottom can greatly reduce welding materials, time and cost, and can improve the structural strength of the original welding mode. The welding time and the materials are reduced, the emission of welding smoke can be reduced, and a certain environment-friendly effect is achieved.
