DETAILED DESCRIPTION

[0027] The utility model is further explained as follows:

[0028] Please refer to Figures 1-10 ,

[0029] The utility model discloses a plug-in endoscope, including display screen 1, first handle 2 and second handle 3, the front end of first handle 2 is hinged with the lower surface middle part of display screen 1 through connecting mechanism 4, the rear end of first handle 2 is inserted with transmission image catheter, one side of the outer wall of first handle 2 is equipped with operation part 5, the other side of the outer wall of first handle 2 is equipped with handle slot 6 for placing second handle 3, the rear end between the two sides inner wall of handle slot 6 is equipped with fixed shaft 61, the rear end side wall of second handle 3 is equipped with shaft hole 31 for the fixed shaft 61 passes through, when holding first handle 2 is inconvenient in endoscope use process, can rotate second handle 3 from handle slot 6, and it is more convenient for the user to hold and observe display screen 1, preferably, the rear end between the rear end of second handle 3 and handle slot 6 is equipped with gap, the included angle between the axial direction of second handle 3 and the axial direction of handle slot 6 is 0 ° ~ 125 °.

[0030] Further, the connecting mechanism 4 comprises a connecting groove 41, a connecting shaft 42 and a rotating block 43. The rear end of the second handle 3 is provided with the connecting groove 41, which is a square structure with a hollow side wall and an open rear end. The connecting shaft 42 is arranged between the two side inner walls of the connecting groove 41. The lower outer wall of the rotating block 43 is provided with a connecting hole for the connecting shaft 42 to pass through. The top of the rotating block 43 is connected to the middle of the lower surface of the display screen 1. The automatic limiting mechanism 7 is arranged between the outer wall of the rotating block 43 and the inner wall of the connecting groove 41. The display screen 1 is connected to the top of the rotating block 43. The bottom of the rotating block 43 can rotate around the connecting shaft 42 by a certain angle, so that the operator can adjust the display screen 1 to a suitable angle for observation. Preferably, the angle between the lower surface of the display screen 1 and the horizontal direction is 0-80°.

[0031] Further, the lower inner side of the outer wall of the rotating block 43 is provided with the automatic limiting mechanism 7. The connecting shaft 42 is arranged between the two side inner walls of the connecting groove 41. A plurality of limiting holes 8 matched with the automatic limiting mechanism 7 are arranged in a ring array with the connecting shaft 42 as the center and the distance between the connecting shaft 42 and the center of the automatic limiting mechanism 7 as the radius. By arranging the automatic limiting mechanism 7, the display screen 1 can be rotated to a suitable angle without accidentally rotating during work, which affects the observation process.

[0032] Further, the automatic limiting mechanism 7 comprises a limiting block 71, a limiting groove 72 and a compression spring 73. The lower inner side of the outer wall of the rotating block 43 is provided with the limiting groove 72 for the sliding of the limiting block 71. The inner end wall of the limiting groove 72 is connected to the inner end surface of the limiting block 71 through the compression spring 73. The inside of the limiting block 71 is in a cylindrical structure. The outside of the limiting block 71 is in a hemispherical structure. The outside of the limiting block 71 is matched and engaged with the limiting hole 8. As shown in Figure 4 When it is necessary to adjust the angle of the display screen 1, the display screen 1 is rotated clockwise so that the inner wall of the limiting hole 8 exerts a force on the hemispherical structure of the outside of the limiting block 71. The force acting on the surface of the hemispherical structure generates a partial force towards the limiting groove 72, which pushes the outside of the limiting block 71 into the limiting groove 72. At this time, the compression spring 73 is in a compressed state. When moving to the next limiting hole 8, the hemispherical structure of the outside of the limiting block 71 is popped out and matched and engaged with the limiting hole 8 due to the resetting action of the compression spring 73, completing the automatic limiting. Similarly, as shown in Figure 5 When the automatic limiting mechanism 7 is engaged with the uppermost limiting hole 8, the display screen 1 is not rotated by external force in the normal working state, which does not cause the limiting block 71 to disengage from the limiting hole 8.

[0033] Further, as shown in Figures 7-10 The top of the rotating block 43 is connected with the bottom end of the connecting rod 44, the top end of the connecting rod 44 is provided with a spherical connecting piece 45, and the bottom of the display screen 1 is provided with a rotating groove 46 for rotating the spherical connecting piece 45, so that the display screen 1 can be rotated to a comfortable angle according to the observation needs of the user.

[0034] The above is only the embodiment of the present application, and does not limit the patent range of the present application, and any equivalent transformation or direct or indirect application in the related technical field by using the content of the present application specification and drawings is also included in the patent protection range of the present application.
