Base for dismountable panel of automobile radio cassette player

A base for a dismountable panel of an automobile radio cassette player adopts the structure that a lock catch seat is arranged on the base; an insertion hole is formed on the side edge of the base; the lock catch seat comprises a sliding groove, a locking lock catch and a spring; the locking lock catch can slide up and down in the sliding groove through a distortion spring; a hook is arranged on the head of the locking lock catch; a lift-out plate is arranged on the base; and a lift-out spring is arranged at the lower end of the lift-out plate and is a compression spring. Through the adoption of the lift-out plate with the compression spring, the lift-out plate can lift the panel out automatically when the locking lock catch is unlocked during the dismounting of the panel, so that the operation of pulling out the panel by hand synchronously is eliminated. Therefore, the base has the advantage of convenience in use.
