In this embodiment, the base 10 is set as a cylinder, and the outer diameter of the endoscope 1 is the same as the diameter of the fixing hole so as to be embedded in the fixing hole. In other embodiments, the base 10 can also be set as a square or a special-shaped one.

[0040] Furthermore, the fixing assembly 20 includes claw jaws 21. The claw jaws 21 are multiple and are arranged at intervals on the circumferential side of the fixing hole. All the claw jaws 21 can move radially along the fixing hole simultaneously to lock or release the endoscope 1.

[0041] Specifically, the base 10 further includes a fixing step 11. The fixing step 11 is arranged on one side of the base 10 and a through hole is provided at the center. The through hole corresponds to the fixing hole. The claw jaw 21 includes a clamping groove which can be clamped on both sides of the circumferential wall of the fixing step 11 and there is a gap between the clamping groove and the circumferential wall of the fixing step 11. The claw jaw 21 can move radially along the through hole through the gap.

[0042] In this embodiment, the fixing step 11 is set as a square, and there are four claw jaws 21. The four claw jaws 21 are evenly spaced to tightly clamp the endoscope 1 evenly. The four claw jaws 21 are respectively arranged at the four edges of the fixing step 11. Specifically, the side of the claw jaw 21 for abutting against the endoscope 1 is set as an arc-shaped side wall, and the radian of the arc-shaped side wall is the same as the radian of the through hole and the fixing hole. In other embodiments, the fixing step 11 can also be set as a circle. At this time, the side walls of the claw jaws 21 on both sides of the fixing step 11 are both set as arc-shaped side walls. Specifically, the thickness of the claw jaw 21 is the same as the height of the fixing step 11.

[0043] Furthermore, an abutting block 31 is arranged on the inner side of the locking ring 30. The abutting block 31 extends along the circumferential direction of the locking ring 30 and abuts against the end face of the base 10. The locking ring 30 is arranged on the circumferential wall of the base 10 through the abutting block 31 and can rotate around the central axis of the base 10. The abutting block 31 is set as a wedge shape and corresponds to the claw jaw 21 one by one. Rotating the locking ring 30 drives all the abutting blocks 31 to abut against or disengage from the claw jaws 21 simultaneously.

[0044] By rotating the locking ring 30 to control the movement of the claw jaws 21, the endoscope 1 can be locked or released, which improves the positioning reliability of the endoscope 1 during the operation, simplifies the cumbersome degree of the replacement operation of the endoscope 1, facilitates the operation of medical staff, saves time and improves efficiency.

[0045] Furthermore, refer to Figure 4The fixing assembly 20 also includes a reset spring 22. A fixed shaft 212 is provided on the claw 21. The reset spring 22 is wound around the fixed shaft 212 and its two ends are fixed to the side wall of the fixed step 11. The movement of the claw 21 can change the tightness of the winding between the reset spring 22 and the fixed shaft 212. In this embodiment, the reset spring 22 is pre-compressed, and clearance holes are provided on both sides of the claw 21. After pre-compression, the two ends of the reset spring 22 pass through the clearance holes and abut against the fixed step 11, so that the reset spring 22 can adjust the position of the claw 21. In other embodiments, the two ends of the reset spring 22 can be welded or bonded to the fixed step 11 after passing through the clearance holes. When the abutment block 31 abuts against the claw 21 and causes the claw 21 to move in a direction close to the endoscope 1, the reset spring 22 is tightened at the fixed shaft 212 to lock the endoscope 1. When the abutment block 31 is disengaged from the abutment with the claw 21, the reset spring 22 drives the claw 21 to disengage from the endoscope 1 due to its own elastic restoring force, and releases the endoscope 1.

[0046] In other embodiments, a spring may be provided between the claw 21 and the fixed step 11 to reset the claw 21 by utilizing the elastic restoring force of the spring.

[0047] Further, the endoscope fixing structure also includes an annular cover plate 40, the outer diameter of the annular cover plate 40 is the same as the inner diameter of the locking ring 30, and the annular cover plate 40 is fixed to the side of the base 10 where the fixing step 11 is set to limit the claw 21 and the locking ring 30 from being separated from the base 10. In this embodiment, a plurality of shaft holes 111 are arranged at intervals on the end surface of the fixing step 11, and a shaft rod 41 is correspondingly arranged on the annular cover plate 40, and the shaft rod 41 is plugged into the shaft hole 111. Specifically, there are four shaft holes 111, which are respectively located at the four corners of the fixing step 11, and there are four shaft rods 41 correspondingly arranged, and a transition fit can be adopted between the shaft rod 41 and the shaft hole 111. In other embodiments, the fixing step 11 can be set on one side of the annular cover plate 40, and the end surface of the fixing step 11 is provided with a shaft hole 111, and the shaft rod 41 is arranged at the position corresponding to the locking ring 30 to fix the annular cover plate 40 and the locking ring 30, and the relative motion relationship between the claw 21, the reset spring 22 and the fixing step 11 remains unchanged. In other embodiments, threaded holes may be provided at the four corners of the fixing step 11, and positioning holes may be provided at corresponding positions of the annular cover plate 40, and fasteners may be passed through the positioning holes and screwed to the threaded holes to fix the annular cover plate 40. The annular cover plate 40 and the fixing step 11 jointly limit the position of the claw 21 to prevent the claw 21 from being separated from the base 10; the annular cover plate 40 and the abutment block 31 jointly limit the position of the locking ring 30 to prevent the locking ring 30 from being separated from the base 10.

[0048] Further, the circumferential wall of the locking ring 30 is provided with protruding portions 32 at intervals, and a high-friction area is provided on the circumferential side of the protruding portions 32. Specifically, two protruding portions 32 are symmetrically arranged on the locking ring 30, which is convenient for medical staff to screw the locking ring 30.
