[0007] Further, the splicing vertical plate is inserted between the upper and lower adjacent top hole mold and bottom hole mold, and the splicing horizontal plate is inserted between the left and right adjacent top hole mold and bottom hole mold.

[0008] Further, adjusting holes are provided on the front surfaces of the top hole mold and the bottom hole mold; and an adjusting stud is screwed in the adjusting hole.

[0009] Further, a strip-shaped pressing plate is attached to the front surface of the splicing horizontal plate; and the strip-shaped pressing plates are symmetrically fixed at the left and right edges of the front surface of the splicing horizontal plate.

[0010] Further, a strip-shaped pressing plate is attached to the front surface of the splicing horizontal plate; and the strip-shaped pressing plates are symmetrically fixed at the left and right edges of the front surface of the splicing horizontal plate.

[0011] Furthermore, the top hole mold, the bottom hole mold, the external stud, and the internal threaded cylinder column form an adjustable rectangular hole mold structure.

[0012] The beneficial effects of the present utility model are as follows. The reserved hole mold for the elevator shaft call box of the present utility model uses two sets of symmetrically distributed top hole molds and bottom hole molds to form a rectangular reserved frame. By rotating the external stud in the internal threaded cylinder column, the distance between the top hole mold and the bottom hole mold is adjusted, and the appropriately cut splicing vertical plates, splicing horizontal plates, and flat plates are distributed and fixed on the sides and rear ends of the top hole mold and the bottom hole mold, realizing an adjustable reserved hole mold, which is convenient for adjusting the size of the reserved hole mold according to different sizes of the elevator shaft call box, making the holes reserved on the elevator shaft wall more flat, reducing the error generated by drilling with a drill bit, and improving the installation effect of the elevator shaft call box.
