In the process of disassembling the spring cylinder, the upper cover 3 needs to be disassembled firstly, and because the spring 1 has a larger stiffness coefficient and because the pretightening force provided by the spring 1 for the upper cover 3 is too large, if the upper cover 3 is directly rotated, the disassembly is more laborious; moreover, if the upper cover 3 is directly removed, the spring 1 will also burst out, which has certain danger; therefore, the spring 1 needs to be pressed to prevent the above-mentioned problems when the spring is removed. Usually, when the cylinder body 2 and the upper cover 3 are disassembled, one person is responsible for disassembling the cylinder body and the upper cover 3, and the other person is responsible for pressing the spring 1, so that the cost of human resources is consumed. In order to reduce the number of required workers in the process of disassembling the spring air cylinder, the utility model provides a disassembling tool for a printer cutter frame air cylinder.
