[0025] It also includes a sliding sleeve 401 fixedly connected to the rack 301 . A guide rod 4 is fixedly connected to the drying box 1 , and the sliding sleeve 401 is slidably connected to the guide rod 4 .

[0026] The driving part comprises an electric telescopic rod 3 , which is fixedly connected to the drying box 1 , and the sliding sleeve 401 is fixedly connected to the electric telescopic rod 3 .

[0027] When in use, firstly, the two ends of the welding rod to be dried are inserted into the positioning hole 202 of the axis of the rubber block 201 through the insertion groove 203, so as to limit and fix the welding rod, and then the sealing cover 101 is covered on the drying box 1, so as to close the drying box 1, and then the electric heating net 102 is turned on, so that the electric heating net 102 is heated to generate heat, so as to dry the welding rod;

[0028] At the same time, the electric telescopic rod 3 is started, and the electric telescopic rod 3 pushes the sliding sleeve 401 to slide back and forth on the guide rod 4. At the same time, the rack 301 follows the sliding sleeve 401 to move back and forth on the guide rod 4, and drives the rotating shaft 2 to rotate by meshing with the gear 302. The rotating shaft 2 drives the welding rod to rotate synchronously, which is beneficial for the electric heating network 102 to evenly heat and dry the welding rod, thereby improving the drying effect of the welding rod.

[0029] Embodiment 2:

[0030] Reference Figure 1 , Figure 2 and Figure 4 , a welding rod drying machine, which is basically the same as the embodiment 1, and further, a sealing plug 5 is fixedly connected to the sealing cover 101, and a sealing gasket 501 is fixedly installed on the outer wall of the sealing plug 5, and the sealing gasket 501 is in contact with the inner wall of the drying box 1.
