[0035] Main slot 3, main slot 3 is opened at the upper end of RS485 socket 2;
[0036] The anti-reverse slot 4 is provided at the upper end of the RS485 socket 2;
[0037] RS485 module mainboard 5, RS485 module mainboard 5 is slidably connected in the main slot 3 and the anti-reverse slot 4;
[0038] The fixing component is provided with two groups, each group of fixings includes a reinforcement groove 6, a reinforcement block 7, a limit sleeve 8, a limit slider 9 and a spring 10.

[0039] In a specific embodiment of the present utility model, the RS485 socket 2 is an ordinary RS485 module plug interface, and a main slot 3 and an anti-reverse slot 4 are provided at the upper end, and a fixing component for fixing the RS485 module motherboard 5 is arranged between the sockets of the main slot 3 and the anti-reverse slot 4, and a main connection port and an anti-reverse socket are provided at the lower end of the RS485 module motherboard 5, which are respectively inserted into the main slot 3 and the anti-reverse slot 4, and a limiting slider 9 slides in a limiting sleeve 8 to limit the sliding direction of the reinforcement block 7 to prevent the reinforcement block 7 from shifting. The reinforcement block 7 is arranged on one side inner wall of the anti-reverse slot 4 of the main slot 3, and does not affect the electrical connection between the RS485 socket 2 and the RS485 module motherboard 5. When the RS485 module motherboard 5 is inserted When in the RS485 socket 2, the main connection port and the anti-reverse socket of the RS485 socket 2 squeeze the side of the reinforcement block 7, pushing the reinforcement block 7 into the reinforcement groove 6. The reinforcement block 7 squeezes the spring 10 to contract when sliding. When the RS485 module mainboard 5 is fixed, the spring 10 is always in a compressed state. The rebound force of the spring 10 makes the two reinforcement blocks 7 press against the two sockets of the RS485 module mainboard 5, thereby increasing the friction between the RS485 socket 2 and the RS485 module mainboard 5, helping to fix the RS485 module mainboard 5. When the device is collided, the RS485 module mainboard 5 will not become loose due to the fixation of the RS485 module mainboard 5 by the reinforcement block 7, resulting in poor contact.

When the flow integrator body 1 is inserted into the shell 14, the shell 14 squeezes the mounting block 13 and bends until the mounting block 13 is stuck in the mounting hole 12. At this time, the contact end of the mounting hole 12 and the mounting block 13 is a straight surface, so that the flow integrator body 1 can no longer be pulled out of the flow integrator body 1. When it needs to be removed, the mounting block 13 is squeezed inward out of the mounting hole 12, and then the flow integrator body 1 is pulled out.
[0048] For details, please refer to Figure 1-Figure 5 The operating end of the flow totalizer body 1 is provided with seven operating keys, and the seven operating keys are all silicone-type circular.
