DETAILED DESCRIPTION

[0016] The specific implementation of the present application is further described below in conjunction with the accompanying drawings.

[0017] In the description of the present application, it should be understood that the terms "first", "second", etc. are used to distinguish similar objects, rather than to describe or indicate a specific order or sequence. The terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the referred device or element must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0018] like Figures 2 to 6As shown, the optical path adjustment structure of the laser opposing beam sensor involved in the present application includes a connecting plate 3, which is bent and includes a horizontal portion and a downward inclined portion. The horizontal portion of the connecting plate 3 is used to be fixed to the lower surface of the foot pedal 100 of the doctor's operating end through a first connecting member 4. Specifically, the first connecting member 4 can be a flat round head screw; two oblong holes 5 are provided at intervals on the inclined portion of the connecting plate 3. In this embodiment, the two oblong holes 5 are arranged in sequence along the front-to-back direction, and each oblong hole 5 is provided with a second connecting member 6, such as a flat round head screw. The two second connecting members 6 are also used in conjunction with the two connecting holes provided on the laser opposing beam sensor-emitting end 2. The laser opposing beam sensor-emitting end 2 is located on the upper surface of the inclined portion of the connecting plate 3. By adjusting the position of the second connecting member 6 in the oblong hole 5, the second connecting member 6 is then fastened to the connecting hole on the laser opposing beam sensor-emitting end 2, so that the position of the laser opposing beam sensor-emitting end 2 can be adjusted, thereby adjusting the laser line A. By designing the connecting plate 3 to be bent, the laser beam sensor-transmitting end 2 can have a certain tilt angle, which can basically correspond to the laser beam sensor-receiving end 1, and the tilt angle of the laser beam sensor-transmitting end 2 can be fine-tuned subsequently.

[0019] At least one screw hole is provided on the inclined portion of the connecting plate 3. In the present embodiment, three screw holes are provided at intervals near the edge of the inclined portion of the connecting plate 3. A set screw 7 is threadedly connected to the screw hole. The end face of the set screw 7 is used to abut the surface of the laser beam sensor-transmitting end 2. When the second connecting member 6 is fastened to the connecting hole on the laser beam sensor-transmitting end 2, the surface of the laser beam sensor-transmitting end 2 is attached to the upper surface of the inclined portion of the connecting plate 3. Since the shell of the laser beam sensor is made of plastic, the end face of the set screw 7 can be abutted against the surface of the laser beam sensor-transmitting end 2 by fine-adjusting the screwing degree of the set screw 7 at the screw hole, so that one end of the laser beam sensor-transmitting end 2 is fixed with the second connecting member 6 as a fixed point, and the degree to which the other end of the laser beam sensor-transmitting end 2 is away from the inclined portion of the connecting plate 3 is fine-adjusted, for example, 0 to 2°; in this way, the position of the laser beam sensor-transmitting end 2 can be adjusted, and then the laser circuit A can be adjusted.

[0020] A laser refraction plate 8 is also provided at the reserved groove position of the foot pedal 100. The laser emitted from the laser opposing beam sensor-transmitting end 2 is refracted by the laser refraction plate 8 and then emitted to the laser opposing beam sensor-receiving end 1 installed on the foot pedal 100. In this embodiment, the laser opposing beam sensor-receiving end 1 is installed on the foot pedal 100 by means of a cylindrical head screw 9.

[0021] In the specific use process, the laser beam sensor-receiving end 1 is assembled at a preset position in the foot pedal 100, and the horizontal part of the connecting plate 3 is assembled at the lower surface of the foot pedal 100. By adjusting the position of the second connecting member 6 in the oblong hole 5, the second connecting member 6 is fastened to the connecting hole on the laser beam sensor-transmitting end 2, so that the position of the laser beam sensor-transmitting end 2 can be adjusted, and then the laser line A can be adjusted. If the laser line A after the above adjustment still cannot meet the requirements, the screwing degree of the set screw 7 at the screw hole can be fine-adjusted so that the end face of the set screw 7 abuts against the surface of the laser beam sensor-transmitting end 2, and then the degree to which the laser beam sensor-transmitting end 2 is away from the connecting plate 3 can be fine-adjusted, so that the position of the laser beam sensor-transmitting end 2 can be further adjusted, and then the laser line A can be adjusted to align with the laser beam sensor-receiving end 1.

[0022] The optical path adjustment structure of the laser beam sensor involved in the present application can adjust the laser line at any time according to needs, and there is no need to remove the foot pedal for adjustment. The optical path adjustment structure has the advantages of simple structure, reliable operation, easy use, low cost, easy operation, easy adjustment, easy calibration, and no need for multiple assembly and disassembly.

[0023] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
