The invention discloses an adjustable coded lock. The lock comprises a lock body, a door frame lock, and a key. The lock body comprises a main locking-tongue and an auxiliary locking-tongue respectively fixed on the front ends of two positioning push rods. The positioning push rods are connected through a hinge sheet in a linkage manner. The two positioning push rods respectively pass through positioning sliding grooves. The front end of the positioning push rod is fixedly provided with a front positioning plate, a return spring is sleeved on the front positioning plate. The tail end of the first positioning push rod is fixedly provided with a rear positioning plate. The second positioning sliding groove is provided with a main lock and an auxiliary lock. The main lock is fixed on the second positioning sliding groove. The main lock is a fixing block which is provided with a plurality of holes. Each hole is internally provided with a rotary thread push rod and a push rod mother body. The push rod mother body is provided with a positioning steel ball. The auxiliary lock is a sliding block which is provided with holes in the same number with the main lock. The sliding block is slidably installed in the second positioning sliding groove. Each hole is internally provided with a plug whose top end is provided with a spring. A steel lathing on a side of an opening of the door frame lock can rotate upward to an outer side, the size of the opening being equivalent to the size of the auxiliary lock tongue. The lock is simple in manufacturing, low in price, and high in safe reliability.
