[0035] As a technical optimization solution of the present invention, by providing a compression spring 13 , the base plate 9 can be supported to prevent the excessive movement of the crank 11 from affecting the movement of the base plate 9 .

[0036] refer to Figure 6 A sealing ring 14 is fixedly connected to the bottom of the bottom plate 9, and a sealing groove 15 is opened on the surface of the piston 8.

[0037] As a technical optimization solution of the present invention, by providing a sealing ring 14 and a sealing groove 15, the sealing effect of the piston 8 can be improved to prevent leakage of gas inside the suction cup 4.

[0038] refer to Figure 1 The left and right sides of the front of the transmission device body 1 are fixedly connected with vertical plates 16, and the interior of the vertical plates 16 is movably connected with a shaft 17.

When the storage disk 2 is installed, the rotating wheel 5 is rotated, and the rotating wheel 5 drives the bidirectional screw 6 to rotate. The bidirectional screw 6 uses the thread to push the two screw sleeves 7 to move outward. During the movement, the screw sleeves 7 pull the two cranks 11 to rotate towards each other. The crank 11 pulls the piston 8 down through the bottom plate 9 and increases the internal pressure of the suction cup 4. During the rotation process, the bidirectional screw 6 can also rotate the driven wheel 19 through the transmission wheel 20. The driven wheel 19 drives the extrusion plate 18 to swing around its own axis through the shaft 17. When the back of the extrusion plate 18 contacts the surface of the storage disk 2, the storage disk 2 and the transmission device body 1 are synchronously fixed.

[0047] To sum up: the LoRa-based 4-20mA signal data storage and transmission device, by adsorbing the transmission device body 1 on the surface of the wall through the suction cup 4, and then rotating the wheel 5, the wheel 5 drives the bidirectional screw 6 to rotate, and the bidirectional screw 6 uses the thread to push the two screw sleeves 7 to move outward.

At the same time, it is inconvenient for users to quickly disassemble and assemble the data storage and transmission device, which seriously affects the scope of application of the data storage and transmission device.
