[0019] The base 1 is fixedly provided with a locking sleeve 2. In this embodiment, the locking sleeve 2 and the base 1 are fixed by a rivet 6.

[0020] The locking sleeve 2 is provided with two clamping assemblies for clamping the drainage tube 10 at intervals, each clamping assembly comprising a pair of arc-shaped clamping plates 3, and the upper and lower ends of each arc-shaped clamping plate 3 are clamping end 31 and connecting end 32 respectively. The structure of the locking sleeve 2 comprises: the sleeve body 21 gradually arches upward from both sides to the middle, the sleeve body 21 is bent downward and inward on both sides to form a folding plate 22, and the folding plate 22 on each side and the sleeve body 21 form a clamping groove 23. The bottom of the sleeve body 21 is provided with two locking pieces 4, the inner and outer sides of each locking piece 4 are respectively flip side 41 and support side 42, and the support side 42 of each locking piece 4 is clamped and supported in the clamping groove 23 on the corresponding side, and the flip side 41 of the two locking pieces 4 is clamped and supported.

[0021] The connecting end 32 of the arc-shaped clamping plate 3 in each clamping assembly passes through the mounting groove 211 on the sleeve body 21 and is fixed with the locking piece 4.

[0022] The clamping and supporting distance between the clamping grooves 23 on both sides in the locking sleeve 2 is less than the sum of the width of the two locking pieces 4 in the flat close state. When the two clamping assemblies are in the unlocked state, the clamping ends 31 of each pair of arc-shaped clamping plates 3 are away from each other, and the flip side 41 of the two locking pieces 4 is inclined upward. When the two clamping assemblies are in the locked state, the clamping ends 31 of each pair of arc-shaped clamping plates 3 are close to each other, and the flip side 41 of the two locking pieces 4 is inclined downward.

[0023] When the two clamping assemblies are in the unlocked state, any pair of arc-shaped clamping plates 3 is pressed by external force, which drives the two pairs of arc-shaped clamping plates 3 to approach each other, and drives the flip side 41 of the two locking pieces 4 to rotate downward around the corresponding support side 42, and when the two locking pieces 4 are rotated to the flat close state, the sleeve body 21 is outwardly supported to make the clamping and supporting distance between the clamping grooves 23 on both sides in the locking sleeve 2 increase, so that the two locking pieces 4 can continue to rotate downward, until the clamping ends 31 of a pair of arc-shaped clamping plates 3 are close to each other, at this time, the clamping assembly is in the locked state.

[0024] Conversely, when the two clamping assemblies are in the locked state, any pair of arc-shaped clamping plates 3 is pried outward by an external force, the two pairs of arc-shaped clamping plates 3 are driven to move away from each other, thereby driving the flip sides 41 of the two locking pieces 4 to rotate upward around the corresponding support sides 42, and when the two locking pieces 4 are rotated to the flat and abutting state, the locking shell 2 can be outwardly supported, the clamping grooves 23 on both sides of the locking shell 2 are elastically deformed, the clamping distance is increased, thereby the two locking pieces 4 can continue to rotate upward, until the flip sides 41 of the two locking pieces 4 are clamped by the inner wall of the locking shell 21, in the embodiment, when the flip sides of the two locking pieces 4 are inclined and upwardly abut against the limiting protrusions 212, the two clamping assemblies are in the unlocked state.

[0025] In order to more reliably lock the drainage tube 10, in the embodiment, a locking adjusting mechanism is further arranged on each clamping assembly, the locking adjusting mechanism comprises: an adjusting threaded hole 301 is arranged at the lower end of each arc-shaped clamping plate 3 of each clamping assembly, a locking screw 312 is arranged in each adjusting threaded hole 301, the inner end of the locking screw 312 is movably connected with a support block 313, the support surface of the support block 313 is in the form of a circular arc, and the locking screw 312 is tightened inwardly, so that the support block 313 is pressed on the drainage tube 10. In order to facilitate adjustment, an adjusting handle 310 is arranged at the outer end of the locking screw 312. In the locked state, the locking screw 312 is further rotated inwardly or outwardly by rotating the adjusting handle 310, so that the drainage tube 10 can be more reliably locked, and the drainage tube 10 can be prevented from being excessively pressed and deformed.

[0026] In use, the base 1 is first pasted on the surgical drape at a suitable position, then any pair of arc-shaped clamping plates 3 is pried, so that the two clamping assemblies are in the unlocked state, the drainage tube can be placed between the two pairs of arc-shaped clamping plates 3, then the arc-shaped clamping plates 3 are pressed inwardly, so that the two clamping assemblies are in the locked state, whether the drainage tube 10 is loose is checked, the drainage tube 10 is further locked by the locking screw 312, the movement of the drainage tube 10 is further effectively prevented, and the use is very convenient.
