When the equipment needs to be moved, the Foma wheel is first switched to mobile mode, and the power and signal lines are removed. The entire set of equipment can be moved directly by pushing the handle of the equipment, which makes the equipment have excellent portability and is convenient for calling between various equipment in the workshop.

[0031] In this embodiment, the precision heating unit 2 is installed on the precision heating unit bracket 13, and mainly includes a heating lamp 21, a lamp holder 22, a heating lamp support rod 23, a sensor bracket 24, and a heating unit support rod 25; one end of the heating lamp support rod 23 is connected to the heating unit support rod 25, and the other end is connected to the lamp holder 22; the heating lamp 21 is connected to the lamp holder 22; one end of the sensor bracket 24 is connected to the heating unit support rod 25, and the other end is connected to the temperature sensor 26;
