Electromagnetic cylinder and assembly tool thereof

The invention discloses an electromagnetic cylinder and an assembly tool thereof, and the electromagnetic cylinder comprises a support part which comprises a U-shaped yoke, a yoke plate and a static iron core; the magnetic core part comprises a coil holder, a push rod, a movable iron core, a coil and an elastic component; the circuit part comprises a PCB (Printed Circuit Board), a terminal and a shell; the PCB is electrically connected with the coil through the terminal, when the coil is electrified, the movable iron core is attracted, and the push rod is pulled to move close to the static iron core; when the coil loses power, the movable iron core is released, and the elastic component drives the push rod to reset. The electromagnetic cylinder is compact in structure, the size of the electromagnetic cylinder can be reduced easily, a three-point fixedly-connected stable installation structure is formed through assembly of the PCB, and reliability can be improved easily; in addition, due to the fact that all t
