The case comprises an inner case body (1), an outer case body (2), a first insertion piece (3) and a second insertion piece (4), the inner case body (1) is provided with a first installation hole (11), the outer case body (2) is provided with a second installation hole (21), the first insertion piece (3) is inserted into the first installation hole (11), and the second insertion piece (4) is inserted into the second installation hole (21). A cavity is formed in the second inserting piece (4), and the end, close to the outer casing (2), of the first inserting piece (3) is located in the cavity and can slide in the cavity. The aero-engine comprises a casing. According to the cartridge receiver, the distance change between the inner cartridge receiver and the outer cartridge receiver in the radial direction can be adapted through the relative movement between the first insertion piece and the second insertion piece, and the stability and reliability of assembly are improved. 本发明涉及一种机匣和航空发动机，其中机匣包括内机匣(1)、外机匣(2)、第
