The end face of the metal piece 32 is provided with a rod insertion hole, the end of the insulator 31 away from the rod insertion hole is coaxially provided with a shaft insertion hole, the second end of the roasting rod 2 is inserted into the rod insertion hole in an interference fit, and the output shaft 11 is inserted into the shaft insertion hole.

[0049] The first isolation piece 3 is arranged, so that when the roasting rod assembly 10 is initially assembled, the second end of the roasting rod 2 can be tightly inserted into the rod insertion hole by a tool. In the subsequent taking and placing process, the roasting rod 2 is taken out of and placed into the inner container 20 by inserting and pulling the output shaft 11 in the shaft insertion hole, and the cleaning after use is realized. The arrangement stability of the roasting rod 2 is ensured, and the cleaning convenience of the roasting rod 2 is improved. At the same time, by arranging the insulator 31 to wrap the outer side of the metal part 32, the insulating connection of the first isolation piece 3 and the output shaft 11 is realized, the structural strength and rigidity of the first isolation piece 3 are enhanced, the problem of torsional damage of the first isolation piece 3 caused by the torque transmitted from the output shaft 11 to the roasting rod 2 is avoided, the service life of the first isolation piece 3 is improved, and the use reliability of the roasting rod assembly 10 is improved, thereby prolonging the service life of the roasting rod assembly 10.

[0052] To improve the structural stability of the first isolation piece 3, the insulator 31 is made of plastic material, and the metal part 32 and the insulator 31 are integrally formed by injection molding, so as to avoid using an additional connecting structure to connect the insulator 31 and the metal part 32, and to ensure that the insulator 31 and the metal part 32 will not be separated during long-term use, thereby improving the long-term use reliability of the first isolation piece 3.

[0053] To further improve the bonding stability of the metal piece 32 and the insulator 31, in the embodiment, the outer side wall of the metal piece 32 is provided with an injection molding groove 323, the injection molding groove 323 is arranged around the metal piece 32, and the material of the insulator 31 is filled in the injection molding groove 323.

The cross section of the rotating rod portion 22 is preferably a circular cross section, so as to ensure the stability and smoothness of the rotation of the rotating rod portion 22 on the second isolation piece 4.

[0058] It can be understood that, since the cross section of the rod main body 21 is a rectangular cross section, the axis of the roasting rod 2 is the center line of the rod main body 21 extending along the length direction thereof.

[0059] In the embodiment, the second end of the roasting rod 2 is rotatably installed on the second isolation member 4, and the second isolation member 4 is provided with a fixing structure for being connected with the inner container 20.

[0077] Further, the roasting rod 2 comprises a rod main body 21 and a connecting end part, the cross-sectional area of the connecting end part is greater than that of the rod main body 21, and the outer side of the connecting end part is integrally injection molded with the first isolation piece 3. By setting the cross-sectional area of the connecting end part to be greater than that of the rod main body 21, the combination area of the insulator 31 and the metal piece 32 can be increased while avoiding the overall size of the roasting rod 2 being too large to pass through food, and the combination stability of the insulator 31 and the metal piece 32 is improved, thereby improving the structural stability of the first isolation piece 3.

[0078] In other embodiments, the first isolator 3 is injection molded on the output shaft 11. Specifically, the output shaft 11 includes a shaft body and a plug-in shaft portion 321 coaxially connected, the outer diameter of the plug-in shaft portion 321 is larger than that of the shaft body, and the first isolator 3 is integrally injection molded outside the plug-in shaft portion 321.

[0079] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation modes of the present application. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present application. Here, it is unnecessary and impossible to enumerate all the implementation modes. Any modification, equivalent substitution and improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application claim.
