Assembling device for power supply production for vehicle-mounted communication

The utility model belongs to the technical field of power supply production and processing, and particularly relates to an assembling device for producing a power supply for vehicle-mounted communication, which comprises a protection assembly, the protection assembly comprises a first groove body, and the first groove body is fixedly connected with a positioning assembly through an air pressure telescopic rod. The air pressure telescopic rod pushes the first groove body to fix the shell, when the rubber soft cushion makes contact with the shell, the shell is pushed and generates counter-acting force at the same time, the counter-acting force slides in the first groove body through the second groove body, the counter-acting force is removed, and then the shell is protected against extrusion damage; when the shell is fixed, the second groove body continues to move into the first groove body, the communicating pipe stops the baffle from moving, at the moment, the baffle extrudes the spring, the guide rod inserte
