1. An auxiliary device for inserting magnets into a casing, comprising a press and casing positioning bases, wherein the press comprises clamping blocks, a lifting rod, having several ejector plates on its circumferential side, is vertically disposed under each clamping block and propped against each casing positioning base by an elastic element, and the ejector plates are in sliding fit to the casing positioning base in the radial direction of the lifting rod; the lifting rod moves up and down to drive the ejector plates to move in the radial direction of the lifting rod, a contact surface, which is configured to contact with the magnet, is disposed on one side of the ejector plate away from the lifting rod, and each clamping block is provided with a first pressing portion configured to exert pressure on the lifting rod, and a second pressing portion configured to exert pressure on the magnet on the side of the ejector plate;
wherein linkage blocks, with upper ends rotatably fixed to the lifting rod and lower ends rotatably fixed to the ejector plate, are connected between the lifting rod and the ejector plate; when the lifting rod moves down, the upper ends of the linkage blocks move down while the lower ends thereof move away from the lifting rod in the radial direction of the lifting rod.
