[0028] The working principle of the utility model is specifically described as follows:

[0029] In the present design, when the catheter fixer is working, firstly, the first fixing belt 201 and the second fixing belt 202 are wrapped around the patient's waist, and the fixing plate 101 is fitted on the patient's abdomen, and then the second fixing belt 202 is passed through the insertion hole 205 in the middle of the second fixing block 204, and the button 206 is pressed. After the button 206 moves downward, it drives the connecting column 207 below it to move downward. After the connecting column 207 moves downward, it drives the tooth plate 208 below it to move downward. After the tooth plate 208 moves downward, the second fixing belt 202 with the rack on the side can smoothly pass through the insertion hole 205. When the second fixing belt 202 passes through the insertion hole 205 and just fits the patient's body shape, the button 206 is released. At this time, the squeezed spring 210 rebounds and resets the tooth plate 208 to the initial position. At this time, the tooth plate 208 is just engaged with the rack on the side of the second fixing belt 202, so that the position of the two fixing belts 202 is fixed;

[0030] When the tooth plate 208 moves upward, it drives the connecting plate 401 on its side to move upward. After the connecting plate 401 moves upward, it presses the first airbag 402. The gas in the first airbag 402 is squeezed into the second airbag 404. The expanded second airbag 404 can cushion the back of the patient when the patient lies down. When the patient lies down, the control valve 403 is tightened so that the gas in the two airbags cannot flow.

[0031] In the present design, when it comes to catheters of different diameters, the knob 102 can be rotated for adjustment. When the knob 102 is rotated, the first transmission shaft 301 connected thereto is driven to rotate. After the first transmission shaft 301 is rotated, the first gear 302 coaxial therewith is driven to rotate. After the first gear 302 is rotated, the two second gears 303 meshing therewith are driven to rotate. After the second gear 303 is rotated, the second transmission shaft 304 to the side is driven to rotate. After the second transmission shaft 304 is rotated, the first transmission wheel 305 is driven to rotate. After the first transmission wheel 305 is rotated, the third transmission wheel 308 is driven to rotate through the second transmission wheel 306. After the third transmission wheel 308 is rotated, the third transmission wheel 308 is driven through the third transmission wheel 308 below it. The fourth transmission shaft 309 drives the fifth transmission wheel 313 to rotate. After the fifth transmission wheel 313 rotates, it drives the third gear 314 to rotate through the sixth transmission shaft 312. After the third gear 314 rotates, it drives the fourth gear 315 meshing therewith to rotate. After the fourth gear 315 rotates, it drives the seventh transmission shaft 316 above it to rotate. The first transmission shaft 301, the fourth transmission shaft 309 and the seventh transmission shaft 316 rotate at the same time, driving the movable plate 104 to move toward the periphery, so that the distance between each movable plate 104 is increased. At this time, the catheter with a larger diameter can be fixed. Conversely, rotating the knob 102 in the opposite direction can fix the catheter with a smaller diameter.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
