Mounting structure for controller

The utility model provides a mounting structure for a controller. The mounting structure comprises a bottom plate, two side fixing plates, two mounting plates, two limiting structures, two locking mechanisms and two pressing and fixing mechanisms, the two side fixing plates are symmetrically arranged on the left side and the right side of the bottom plate, the top of each side fixing plate is correspondingly provided with one pressing and fixing mechanism, the bottom of each side fixing plate is correspondingly provided with one mounting plate, and each side fixing plate is connected with the bottom plate through one locking mechanism; the pressing and fixing mechanism comprises a pressing plate, two fixing screws, two fixing sleeves, two screwing sleeves and two buffer springs. The mounting structure for the controller solves the problems of open circuit, short circuit or other connection in a circuit caused by the fact that a circuit board is likely to loosen or fall off in the operation process due to the
