The direction parallel to the longitudinal direction of the door body is the direction a as shown in fig. 1.
In one embodiment, the distance measuring mechanism 111 may be a non-contact distance measuring mechanism 111 that can measure the distance without contacting the jig, for example, a laser distance meter, as shown in fig. 3, the distance measuring mechanism 111 shown in fig. 3 is a laser distance meter, the data transmission module 112 is a wireless transmission module, the distance measuring mechanism 111 and the data transmission module 112 are integrated together and attached to the upper surface of the lower mold 102 through a permanent magnet 113, so as to simplify the structure and arrangement of the distance measuring mechanism 111.
