[0045] Combination Figures 2 to 7 The specific working principle of the guide wire conveying force measuring device 200 of the present invention is as follows:
[0046] First, the guide wire 300 is inserted into the positioning hole 311 from the insertion hole 313, and then the head end of the guide wire 300 passes through the space between the clamping jaws 312, and then passes through the through hole 321 of the locking sleeve 32, and the tail end of the guide wire 300 is exposed from the insertion hole 313 on the peripheral side of the chuck 31.

Then, the weight balance movement adjustment component 51 of the weight balance device 5 adjusts the position of the support member 52 so that the support member 52 supports the clamp 3. Then, the tension and pressure sensor 4 is driven by the guide wire conveying device 100 to move together with the clamp 3 and the weight balance device 5, and the tension and pressure sensor 4 directly measures the conveying force of the axial feed received by the guide wire 300.

Therefore, when the guide wire conveying device 100 drives the tension and pressure sensor 4 to move together with the clamp 3 and the weight balancing device 5, the axial force on the guide wire 300 positioned on the clamp 3 can be directly fed back to the tension and pressure sensor 4. The tension and pressure sensor 4 can be used to directly measure the axial feeding conveying force on the guide wire 300, and the measurement error is small. At the same time, the utility model also sets a weight balancing device 5, and uses the weight balancing device 5 to support the clamp 3 to resist the gravity moment on the clamp 3, so as to avoid the tension and pressure generated by the gravity of the clamp 3 on the surface of the tension and pressure sensor 4. The accuracy of the tension and pressure sensor 4 in detecting the axial feeding conveying force on the guide wire 300 on the clamp 3 is ensured.
