[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. The toroidal transformer is a large type of electronic transformer and has been widely used in household appliances and other electronic equipment with high technical requirements. Its main purpose is to serve as a power transformer and an isolation transformer. During the production process of the toroidal transformer, the inner hole of the toroidal transformer needs to be epoxy-filled. The toroidal transformer in the prior art is relatively cumbersome during the filling process, and after the filling is completed, a working hammer needs to be used to remove the tooling base from the toroidal transformer. Any slight mistake in the process of drilling and removing the toroidal transformer will affect the installation size and performance of the toroidal transformer, making it inconvenient to use. Therefore, we propose an integrated device for epoxy-filling the inner hole of a toroidal transformer. Utility Model Content

The setting of the positioning rod 7 facilitates the reservation of holes for subsequent installation. The position of the mounting plate 6 can be limited and fixed by moving the clamping block 18 into the interior of the clamping slot 19, so as to facilitate its rapid installation and disassembly.

[0030] Furthermore, the base 1 is internally rotatably connected with a transmission shaft 10 , one end of the transmission shaft 10 is fixedly connected with a second bevel gear 14 , and the outer side of the screw rod 12 is fixedly connected with a first bevel gear 13 used in conjunction with the second bevel gear 14 .
