Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] See also Figure 1-2 The utility model provides a technical solution: a replaceable heating rod, comprising a heating rod 1, a nut 2, a connecting wire 3, a sheath 4, a mounting structure 1 5 and a mounting structure 2 6; the upper end of the heating rod 1 is installed with the mounting structure 1 5 and the mounting structure 2 6, and the mounting structure 1 5 is installed on the upper end of the mounting structure 2 6; the sheath 4 is fixed to the upper end of the mounting structure 1 5 through the nut 2; the connecting wire 3 extends into the sheath 4 and is connected to the upper end of the heating rod 1.

[0017] The mounting structure 5 includes a mounting body 7, a connecting body 8, a limiting ring 9 and a buckle 10; the mounting body 7 and the connecting body 8 are both cylindrical structures, and the connecting body 8 is fixed at the lower end of the mounting body 7; a limiting ring 9 is arranged on the outer wall of the mounting body 7, and buckles 10 are symmetrically arranged on the lower surface of the mounting body 7, and the buckles 10 are located on both sides of the connecting body 8.

[0018] Furthermore, the connecting body 8 is arranged to protrude downward; the upper end of the mounting body 7 is connected to the sleeve 4 via the nut 2, so that the sleeve 4 and the mounting structure 5 are connected.

[0019] Furthermore, the buckle 10 is an arc-shaped structure with the same shape as the connecting body 8 , and the arc direction is the same as that of the connecting body 8 .

[0020] The mounting structure 2 6 includes a receiving ring 11, a snap-fitting body 12 and an elastic member 13; the receiving ring 11 is fixed to the upper end of the snap-fitting body 12, and a snap-fitting groove 14 is symmetrically arranged on the receiving ring 11; the snap-fitting groove 14 and the buckle 10 are structurally adapted and their positions correspond to each other up and down; the snap-fitting body 12 is symmetrically arranged with an elastic member 13, and an opening 15 is opened on the snap-fitting body 12, and the inner diameter of the snap-fitting body 12 is smaller than the outer diameter of the connecting body 8.
