The wall is rotatably connected to a screw rod 10, and a movable splint 11 is screwed on the outer side of the screw rod 10. The opposite sides of the two clamping plates 8 are fixedly connected to fixed splints 12. The lower side of the movable splint 11 is evenly connected to a spring 13. The spring 13 drives the rubber pressure holding column 14 to press on the upper side of the instrument. According to the convexity and concavity of the instrument surface, the spring 13 produces different degrees of compression deformation. The lower side of the spring 13 is fixedly connected to the rubber pressure holding column 14, and the upper side of the fixed splint 12 is fixedly connected to the buffer rubber layer 15. The rubber pressure holding column 14 can be pressed and fixed according to the shape of the instrument surface. The rubber pressure holding column 14 and the buffer rubber layer 15 can be in flexible contact with the instrument surface to prevent bumps.
[0023] Among them, the lower ends of the two movable plates 7 are movably sleeved on the outside of the auxiliary rod 6, and the lower sides of the two movable plates 7 are slidably set on the upper side of the operating table 3. The left side of the operating table 3 is rotatably connected with a crank 16. By adjusting the crank 16, the two-way screw rod 5 can be rotated to adjust the movement of the movable plate 7. The right end of the crank 16 is fixedly connected to the left end of the two-way screw rod 5. A fixed cavity is opened on the inside of the base 1, and a fixed bolt 17 is movably inserted into the inside of the fixed cavity. The right end of the fixed bolt 17 is fixedly connected to the plug-in plug 18. The plug 18 of the fixed bolt 17 is fixedly connected to the plug-in plug 18. The left end is fixedly connected to a limiting tooth 19, which corresponds to the gear plate 2. The limiting tooth 19 can limit the gear plate 2 to prevent the gear plate 2 from rotating. The outer fixed sleeve of the fixing bolt 17 is provided with a first limiting plate 20, and the outer movable sleeve of the fixing bolt 17 is provided with a return spring 21. The left end of the return spring 21 is fitted with the right side of the first limiting plate 20. The upper side of the clamping plate 8 is rotatably connected to an adjusting button 22. The lower side of the adjusting button 22 is fixedly connected to the upper end of the screw rod 10, and the movable splint 11 is fitted with the clamping plate 8;
[0024] The right side of the right movable plate 7 is rotatably connected to the spline shaft 23, and the left end of the spline shaft 23 is fixedly connected to the right side of the right clamping plate 8. The right end of the spline shaft 23 is fixedly connected to the second limit plate 24. The second limit plate 24 can limit the spline cap 25 to prevent it from falling off. The right end of the spline shaft 23 is movably sleeved with a spline cap 25, and the spline shaft 23 is meshed with the spline cap 25. The second limit plate 24 is located on the inner side of the spline cap 25. The left side of the spline cap 25 is surrounded by a positioning post 26. The right side of the right movable plate 7 is surrounded by a positioning hole 27. The positioning hole 27 is movably plugged into the positioning post 26. Pull the spline cap 25 to the right to make the positioning post 26 disengage from the positioning hole 27. At this time, the spline cap 25 can be flipped with a scale of 60 degrees. After the flip is completed, the spline cap 25 is pushed to the left, so that the positioning post 26 is inserted into the corresponding positioning hole 27, completing the limit fixation of the spline cap 25.
[0025] Working principle: When in use, the bidirectional screw rod 5 is rotated by adjusting the crank 16. According to the size of the instrument, the movable plate 7 is moved to the appropriate position. At this time, the instrument is located on the upper side of the two fixed splints 12. Then the adjusting knob 22 is turned to rotate the screw rod 10, driving the movable splint 11 to sink, so that the spring 13 drives the rubber pressure holding column 14 to press on the upper side of the instrument. According to the concave and convex surface of the instrument, the spring 13 produces different degrees of compression deformation. At this time, the rubber pressure holding column 14 can press and fix according to the shape of the instrument surface, which has a better fixing effect and prevents the instrument from being affected by the concave and convex surface. The pressure force is different, which may cause the danger of deformation. When the instrument needs to be adjusted in direction, the fixing bolt 17 is pulled out by plugging and unplugging the plug 18, so that the limiting tooth 19 is disengaged from the limit of the gear plate 2. At this time, the gear plate 2 can be rotated to rotate the instrument. When the instrument needs to be flipped, the spline cap 25 is pulled to the right to disengage the positioning column 26 from the positioning hole 27. At this time, the spline cap 25 can be flipped with 60 degrees as the scale. After the flip is completed, the spline cap 25 is pushed to the left to insert the positioning column 26 into the corresponding positioning hole 27 to complete the limit fixation of the spline cap 25.
