[0029] In this embodiment, when in use, the external power supply is turned on, and the staff fits one end of the aircraft engine casing with the mounting plate 1, and puts one group of fixing rods 3 and rubber sleeves 301 inside the casing, and controls the motor 203 on the fixing plate 11 to work forward and reversely, driving the driving gear 202 to work forward and reversely, thereby making the multiple racks 201 move relative or reversely, so as to achieve the purpose of making one group of sliding blocks 2 move relative or reversely in the slide groove 101 of the mounting plate 1, which is conducive to moving one group of fixing rods 3 and one group of rubber sleeves 301 to the center of the mounting plate 1, or to the outermost side of the mounting plate 1. When the motor 203 rotates forward, it drives one group of rubber sleeves 301 to fit the inner surface of the casing, and one group of rubber sleeves 301 increases the contact area with the inner surface of the casing after being deformed by force, which is conducive to improving the stability of the fixing work.
[0030] Embodiment 2, as Figure 1-4 As shown, the outer surfaces of the multiple groups of racks 201 are all meshed and connected with the driving gears 202, a base 10 is provided at one end of the mounting plate 1 away from the two groups of fixing rods 3, a fixing plate 11 is fixedly installed at one end of the base 10 close to the mounting plate 1, a motor 203 is fixedly installed on the side of the fixing plate 11 close to the mounting plate 1, and the output end of the motor 203 is fixedly installed on the inner surface of the driving gear 202, a rotating plate 5 is installed on one end of the base 10 close to the fixing plate 11 through a bearing, and a plurality of limit grooves 6 are provided on the side of the rotating plate 5 close to the mounting plate 1.
