Of course, a gap is left between the guide wire wheel 5 and the end surface of the sleeve pipe 2, so that the guide wire wheel 5 can rotate along the axis thereof.
[0027] The working principle of the above measuring device is as follows:
[0028] When the wire passes through the guide wire wheel 5, the tension of the wire is transmitted to the elastic body support 1 through the guide wire wheel 5. The resistance strain gauge pasted in the pasting groove 101 of the elastic body support 1 can convert the deformation of the elastic body support 1 into a change in resistance, and the PCB board 3 in the clamping groove 1031 of the mounting column 103 can convert the output of the resistance strain gauge into an electric signal. Thus, the tension of the wire can be measured quickly and conveniently, and the response speed is fast.
[0029] The elastic body support 1 is made of 2A12 aluminum alloy material and has a certain elasticity.
