The two orange halves are respectively pressed against one of the juicer heads 7 so that the juicer head 7 can squeeze the juice from the orange halves; the driving assembly includes a support seat 91, a planetary reduction gear set 92 and a high-speed motor 93; the support seat 91 is fixed on the lower end of the support cover 2, the high-speed motor 93 is fixed in the middle of the lower end of the support seat 91, the planetary reduction gear set 92 is arranged in the middle of the inner side of the support seat 91, the input end of the planetary reduction gear set 92 is transmission-connected with the output shaft of the high-speed motor 93, and a transmission gear 81 is coaxially arranged at the lower end of each transmission shaft 8, and the two transmission gears 81 are respectively located on the left and right sides of the output gear 921 of the planetary reduction gear set 92 and are meshed with the output gear 921; the above-mentioned high-speed motor can be a series-excited motor or a DC motor.

[0021] Two switch assemblies are fixed on the outer bottom of the support seat 91, and the two switch assemblies correspond vertically to one of the transmission shafts 8 respectively; each transmission shaft 8 can be vertically movably arranged in the support cover 2, the juice storage plate 3 and the filter plate 4, and the lower end of each transmission shaft 8 is connected to a trigger member 10, and the lower end of each trigger member 10 is movable through the bottom of the support seat 91 and then extends out of the support seat 91; when the pressure cover 6 presses the two orange halves against one of the juicer heads 7 to move the transmission shaft 8 downward, each trigger member 10 moves downward with the transmission shaft 8 and triggers the switch assembly at the corresponding position to turn on the switch assembly; the two switch assemblies are connected in parallel, and the high-speed motor 93 is connected in series with the two The switch components connected in parallel are then electrically connected to the power line; a reset structure is provided between each trigger member 10 and the support seat 91, and the reset structure is used to drive the trigger member 10 to move up and reset so that the trigger member 10 releases the trigger state of the switch component; after adopting this structure, when the pressure cover presses the two orange halves against one of the juicer heads respectively to move the transmission shaft downward, each trigger member moves downward with the transmission shaft and triggers the switch component at the corresponding position to turn on the switch component. Since the two switch components are connected in parallel, as long as one of the switch components is turned on, the high-speed motor can be powered on and rotated (since the orange is cut manually, the thickness of the two halves of the orange after cutting may vary). In the case of inconsistency, when the two orange halves press the juicer head, the switch assembly on the thinner orange half side may not be reliably triggered.
