4. The automatic medical suture diameter tester according to claim 3, characterized in that: The rotary servo 1 (603) is connected to the rotary shaft 1 (604) through a coupling. The rotary shaft 1 (604) is connected to the rotary support base 1 (602) through a bearing. The wire clamping substrate 1 (605) is connected to the rotary shaft 1 (604) through screws. The guide post 1 (607) is slidably connected to the movable clamping plate 1 (606). The locking screw 1 (608) is connected to the wire clamping substrate 1 (605) through a thread, and a movable hole is provided on the movable clamping plate 1 (606) around the locking screw 1 (608).

5. The automatic medical suture diameter tester according to claim 4, characterized in that: The lifting and adjusting motor (804) is connected to the lead screw on the vertical lead screw transmission mechanism (802) through a key. The horizontal sliding seat plate (801) is connected to the vertical lead screw transmission mechanism (802) through screws. The electronic dial indicator (806) is fixed to the dial indicator clamp (805) through the locking screw (807). The horizontal sliding seat plate (801) is connected to the load cell (808) through screws.

6. The testing method of the automatic medical suture diameter tester according to claim 2, characterized in that: It includes the following steps: S101. When using this device, first insert the external power cord into the power plug (15), and turn on this device through the power switch (14) to make it enter the operating state; S102. Then, control the servo motor at the end of the 90-degree adjustment position lead screw adjustment mechanism (3) to work through the controller (10), drive the suture tightening adjustment mechanism (6) to act, so that the distance between the suture tightening adjustment mechanism (6) and the suture rotation force measuring assembly (12) matches the length of the suture to be measured. Then, by rotating the locking screw 1 (608) and the locking screw 2 (1209), clamp the two ends of the suture between the wire clamping substrate 1 (605) and the movable clamping plate 1 (606) and the wire clamping substrate 2 (1206) and the movable clamping plate 2 (1207); S103. Then adjust the dial indicator clamp (805) in the wire diameter measuring assembly (8), align the measuring needle of the electronic dial indicator (806) with the suture, and then fix it through the locking screw (807); S104. During the measurement process, the controller (10) can control the servo motor at the end of the 90-degree adjustment position lead screw adjustment mechanism (3) to work, drive the suture tightening adjustment mechanism (6) to act, and tighten the suture. The tensile force sensor (1205) can measure the tensile properties of the suture in real time; S105. Control the first rotary steering gear (603) and the second rotary steering gear (1203) to rotate a certain angle through the controller (10), and then measure the height of the measurement position at each different angle in real time through the electronic dial indicator (806), so as to realize the measurement at the quarter point of the line, 0-degree measurement, 90-degree measurement; at the half point of the line, 0-degree measurement, 90-degree measurement; at the three-quarter point of the line, 0-degree measurement, 90-degree measurement, avoiding the errors caused by manual detection, that is, obtaining the size coordinates of three different points on the same cross-section of the suture line, and the diameter size of the suture line can be calculated, so as to realize the rapid measurement of the suture line diameter.
