And a connecting bulge accommodating port 6-1c is formed in the support plate 6-1 and communicated with the second mounting port of the main rod body, and is used for accommodating the connecting bulge 5-4. The butt joint hole 6-3a is arranged on the second main rod body installation bulge 6-3. The second connecting piece 6-4 is used for connecting the connecting hole 5-4a on the connecting projection 5-4 with the butt-joint hole 6-3a on the second main rod body mounting projection 6-3 so as to enable the stress piece 5 to rotate relative to the stress base 6.

The supporting plate 6-1 is provided with a clamping hole 6-1a which is matched and connected with the clamping bulge 7-3 of the lower shell. When the stress base 6 is connected with the lower shell 7, only the clamping hole 6-1a of the supporting plate 6-1 needs to be clamped on the lower shell clamping bulge 7-3 of the lower shell bottom plate 7-1, so that the assembly operation of the sensor is very convenient.
And the lower shell surrounding plate 7-2 is provided with a bandage inlet and outlet, and the bandage inlet and outlet are matched with the bandage mounting groove 5-3 and the bandage tensioning bulge 6-5, so that the bandage and the sensor are conveniently mounted. The lower shell bottom plate 7-1 and the lower shell enclosing plate 7-2 are provided with a first pair of interfaces 7-4 matched with the clamping bodies 5-5 and a second pair of interfaces 7-5 matched with the connecting bulges 5-4.

The side edge of the clamping plate 5-2 is provided with a bayonet 5-2a which is matched and connected with the clamping bulge 2-3 of the upper shell. The strain gauge accommodating grooves 2-4 can protect the strain gauges, so that the strain gauges are only subjected to the acting force of the stress piece 5, and the measuring accuracy of the sensor is high. The upper shell 2 and the stress piece 5 can be connected only through the upper shell clamping protrusion 2-3 and the bayonet 5-2a, so that the sensor is very simple and convenient to disassemble and assemble. The signal processing circuit board 4 is used for amplifying the resistance change value generated by the strain gauge and converting the resistance change value into a corresponding tension value. In addition, the upper shell enclosing plate 2-2 is provided with a first baffle 2-2a matched with the first pair of interfaces 7-4 and a second baffle 2-2b matched with the second pair of interfaces 7-5.

In addition, the middle part of the first baffle plate 2-2a is provided with a weakening groove 2-2a-1, the weakening groove 2-2a-1 can weaken the rigidity of the middle part of the first baffle plate 2-2a, so that the first baffle plate 2-2a can be bent to a certain extent, and the limiting groove 2-2a-2 of the first baffle plate 2-2a and the limiting bulge 7-2a of the lower shell plate 7-2 can be separated more conveniently.

In addition, as shown in fig. 15, the bottom of the top cover 1 is provided with an insertion buckle 1-2, and the upper shell 2 is provided with a buckle groove 2-5 in matching connection with the insertion buckle 1-2. The top cover 1 and the upper shell 2 can be connected through the plug-in buckles 1-2 and the buckle grooves 2-5, so that the sensor is very convenient to assemble and operate.
The specific application method of the sensor comprises the following steps of firstly separating the first baffle plate 2-2a from the lower shell 7, then separating the clamping joint heads 5-5b from the stress base 6, then rotating the stress element 5 (the stress element 5 rotates relative to the stress base 6 through the connecting bulges 5-4, the top cover 1 and the upper shell 2 can rotate along with the stress element 5), then placing the bandage (the part needing to measure the tension) on the two bandage tensioning bulges 6-5 (as shown in figure 16), then reversely rotating the stress element 5, clamping the clamping joint heads 5-5b with the stress base 6, clamping the first baffle plate 2-2a with the lower shell 7 (at the moment, the bandage can exert the force on the stress element 5 to deform the stress element 5), and finally opening the power supply of the sensor (the strain gauge sends the deformation quantity of the detected stress element 5 to the signal processing circuit board 4, the signal processing circuit board 4 converts the deformation amount into a tension value of the binding belt and sends the tension value to the display screen 1-1), and a user can check the tension value of the binding belt through the display screen 1-1.
