[0006] As a further solution of the utility model: a guide slider is installed on the lower surface of the clamping plate located inside the first slide groove, a wing plate clamping groove is opened in the internal array of the clamping plate, and an anti-slip protrusion is installed on the upper inner side of the wing plate clamping groove.

[0007] As a further solution of the utility model: a strap ring is installed on the outer side of one end of the first strap, and a Velcro is installed on the outer side of one end of the second strap.

[0008] As a further solution of the utility model: the outer diameter dimension length of the anti-drop pad is greater than the inner diameter dimension length of the upper gasket ring, and the connecting rod is movably connected to the clamping plate.

[0009] As a further solution of the utility model: the sleeve hook is a U-shaped component, and the positioning pawl is engaged with the limiting tooth.

[0010] As a further solution of the present invention: the clamping plate is slidably connected to the first sliding groove through the guide sliding block.

[0011] As a further solution of the utility model: an elastic rotating shaft is installed between the positioning pawl and the connecting rod.

[0012] As a further solution of the present invention: the first binding strap and the second binding strap are both fixedly connected to the positioning plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The positioning pawl on the outside of the connecting rod is limited in one direction under the action of the limiting teeth inside the second sliding groove, so that the spacing between the wing plate clamping grooves between the two clamping plates is reduced, and the anti-dropping protrusions inside the wing plate clamping grooves limit the wing plates to ensure the stability of the installation.

[0015] After placing the catheter below the sleeve hook, the sleeve hook is buckled on the top of the catheter under the action of the spring to limit it, and then the catheter is folded multiple times in sequence and limited inside the sleeve hook at different positions, thereby avoiding the need to use too much tape to fix it.

[0023] like Figure 1-5 As shown, the present embodiment provides a catheter fixing device, including a fixing mechanism 1, the fixing mechanism 1 includes: a positioning plate 2, a first binding strap 3, and a second binding strap 4. A clamping plate 5 is arranged above the positioning plate 2, and one side of the clamping plate 5 is located on the upper surface of the positioning plate 2 and is provided with a mounting hole 201. A sleeve hook 6 is installed inside the mounting hole 201. The sleeve hook 6 is a U-shaped component. An anti-slip pad 602 is installed at the lower end of the sleeve hook 6. An upper gasket 202 is installed on the inner side of the upper end of the mounting hole 201. The outer diameter of the anti-slip pad 602 is greater than the length of the upper gasket ring. The inner diameter size length of the gasket 202, a spring 601 is connected between the upper surface of the anti-slip pad 602 and the upper gasket 202, a first slide groove 203 is opened on the upper surface of the positioning plate 2, a second slide groove 204 is arranged on one side of the first slide groove 203, a limiting tooth 205 is installed inside the second slide groove 204, a connecting rod 503 is installed inside the lower surface of the clamping plate 5 located in the second slide groove 204, the connecting rod 503 is movably connected to the clamping plate 5, a positioning pawl 504 is installed outside the connecting rod 503, and the positioning pawl 504 is clamped with the limiting tooth 205.

[0024] like Figure 2-5 As shown, in the present embodiment, the first strap 3 and the second strap 4 are both fixedly connected to the positioning plate 2, an elastic rotating shaft is installed between the positioning pawl 504 and the connecting rod 503, the lower surface of the clamping plate 5 is located inside the first slide groove 203 and a guide slider 505 is installed, the clamping plate 5 is slidingly connected to the first slide groove 203 through the guide slider 505, the internal array of the clamping plate 5 is provided with a wing plate clamping groove 501, the inner diameter length of the wing plate clamping groove 501 of the array is arranged in a decreasing manner, an anti-slip protrusion 502 is installed on the upper inner side of the wing plate clamping groove 501, a strap ring 301 is installed on the outer side of one end of the first strap 3, and a Velcro 7 is installed on the outer side of one end of the second strap 4.
