Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0023] The endoscope handle structure of the preferred embodiment of the utility model is as follows Figure 1-2As shown, it includes a housing 10, a push rod 20 and a locking screw 30, and a rotating wheel 40 for installing a lens traction wire. An annular groove 41 adapted to the traction wire is provided on the circumferential side wall of the rotating wheel 40. Among them, the rotating wheel 40 is arranged in the housing 10. The push rod 20 includes an operating arm 21, and an extension shaft 22 arranged at one end of the operating arm 21. The operating arm 21 is arc-shaped so as to adapt to the contour of the housing 10 and reduce space occupation. The end of the extension shaft 22 away from the operating arm 21 extends into the housing 10 and is coaxially connected to the rotating wheel 40. In order to facilitate processing and manufacturing, the extension shaft 22 and the rotating wheel 40 are detachably connected.

[0024] An annular boss 50 is coaxially provided on the extension shaft 22, and an annular groove 60 adapted to the annular boss 50 is provided on the outer wall of the housing 10. A through hole 100 adapted to the locking screw 30 is coaxially penetrated on both the extension shaft 22 and the rotating wheel 40, and the locking screw 30 passes through the through hole 100. A nut 80 adapted to the locking screw 30 is provided on a side wall of the rotating wheel 40 away from the extension shaft. A support platform 70 connected to the inner wall of the housing 10 is provided on the side of the rotating wheel 40 facing the extension shaft 22, and the diameter of the annular groove 60 is less than or equal to the inner diameter of the support platform 70, and an abutment position is provided on the support platform 70 corresponding to the rotating wheel 40. The utility model has a simple overall structure and is easy to operate. The rotating wheel 40 can be pressed against the support platform 70 by rotating the locking screw 30 to cooperate with the nut 80, which greatly improves the convenience of medical personnel when operating the endoscope. The structural strength of the housing 10 can be increased by providing the support platform 70 and the annular boss 50 . The locking screw 30 directly locks the rotating wheel 40 on the support platform 70 , which can prevent the housing 10 from being deformed inwardly due to the action of the locking screw 30 .

[0025] In this embodiment, a stop rib wall 90 is provided on the rotating wheel 40 to prevent the nut 80 from self-rotating. The stop rib wall 90 and the rotating wheel 40 are integrally injection molded.

[0026] In this embodiment, the support platform 70 is an annular structure and is coaxial with the rotating wheel 40. The outer diameter of the support platform 70 is smaller than the diameter of the rotating wheel 40. A rotating support assembly 110 for supporting the rotating wheel 40 is provided inside the support platform 70. The rotating support assembly 110 includes an elastic annular support member 111, the upper end of which extends out of the upper end of the support platform 70. The rotating support assembly 110 also includes an annular friction pad 112 disposed between the support platform 70 and the rotating wheel 40. The annular friction pad 112 and the annular support member 111 are both coaxially disposed with the locking screw 30. The annular support member 111 and the annular friction pad 112 can effectively buffer and reduce wear, thereby avoiding irreversible wear on the support platform 70 and facilitating replacement of wear parts.

[0027] In this embodiment, a positioning step 120 adapted to the annular support member 111 is coaxially recessed on the upper surface of the support platform 70, and the inner wall of the annular support member 111 is in contact with the outer wall of the extension shaft 22, and the outer wall is in contact with the inner wall of the annular support platform 70, so as to stabilize the extension shaft 22. When assembled in place, a buffer cavity 130 is provided between the annular support member 111 and the inner wall of the housing 10, so that the annular support member 111 has a downward deformation space, so as to avoid the increase of friction between the annular support member 111 and the extension shaft 22 after the annular support member 111 is squeezed.

[0028] In this embodiment, an adjusting screw 140 is provided on a side wall of the rotating wheel 40 away from the annular support member 111. Specifically, a plurality of adjusting screws 140 are provided, and the adjusting screws 140 penetrate the rotating wheel 40. A positioning groove 150 is provided on the annular friction gasket corresponding to the adjusting screw 140. The positioning groove 150 is annular and coaxial with the rotating wheel 40 to facilitate adjustment of the angle of the turntable. In addition, the annular friction gasket is made of metal parts, and the adjusting screw 140 can also directly contact the annular friction gasket to avoid wear caused by contact between the rotating wheel 40 and the support platform 70.

[0029] In this embodiment, a knob handle 160 is provided at one end of the locking screw 30 outside the housing 10 to facilitate operation by medical personnel.

[0030] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all these improvements and changes should fall within the scope of protection of the claims attached to the utility model.
