The invention discloses an extension type table for a bullet train, and relates to the field of transportation. The extension type table comprises an outer table, a motor is arranged in the outer table; an output shaft of the motor is sequentially connected with a first driving bevel gear and a second driving bevel gear; the first driving bevel gear is in engaged transmission with a first driven bevel gear; the first driven bevel gear is fixedly connected with a first lead screw, the first lead screw is in threaded connection with a first sliding block, the first sliding block is rotationallyconnected with a push rod, the other end of the push rod is connected with a fixing block, the fixing block is arranged on the abutting rod, and the second driving bevel gear is in meshing transmission with a second driven bevel gear. The motor is in engaged transmission through two pairs of bevel gears, synchronous outward movement of the abutting rod and the inner table is achieved, and finally,the abutting rod abuts against the check block and the triangular support at the lower end of the inner table so that the stability is good; according to the device, passengers do not need to get upto vacate space, the passengers in the aisle can use the table conveniently, no extra vertical support is arranged below the table, collision of legs of the passengers is avoided, and the experience comfort degree of the passengers is greatly improved.
