POS machine shell stamping device with energy-saving effect

The utility model discloses a POS machine shell stamping device with an energy-saving effect, relates to the technical field of POS machine shell stamping, and aims to solve the problems that an existing stamping device can only conduct punching operation on a POS machine shell at a time, so that the efficiency of the stamping process is low, time and energy are consumed, and a large number of identical objects such as the POS machine shells cannot be machined easily. A supporting base is fixedly installed on the lower portion of the interior of the POS machine shell stamping cabinet. The stamping table is installed on the upper surface of the supporting base, and four annularly-distributed positioning object tables are arranged on the upper surface of the stamping table; the punching end is installed above the punching table, four annularly-distributed installation grooves are formed in the lower surface of the punching end, punching mechanisms are detachably installed in the installation grooves, a thread c
