The end of the button 4 is in contact with the leaf spring 11. The button 4 is pressed, the spring 12 is compressed and deformed under the action of external force, so that the distance between the fixed block 10 and the elastic sheet 11 is pulled, and the catheter is placed and fixed.

As shown in fig. 5, in the second initial state of the embodiment of the clamping assembly, the button 4 is in the bouncing state, the elastic sheet 11 and the two springs 12 are in a natural non-compression state, a conduit channel is left in the middle but the conduit cannot be directly inserted into the conduit, and at this time, the boss on the button 4 is attached to the protective shell 5, is just in the limited bouncing range of the button 4, and plays a role in fixing the button 4 and the holder main body 3 and preventing displacement.

As shown in fig. 7, when the button 4 is pressed, the channel is in an open state, the bottom of the button 4 drives the contacted elastic sheet 11 to displace, and drives the two springs 12 to compress and deform, i.e. move to a set limited range, so that the button 4 keeps the channel open for a certain time. At this moment, the channel between the elastic sheet 11 and the fixing block 10 is opened to be enlarged, the conduit can be placed in the channel, when the conduit is placed at a specified placing position, the button 4 can be loosened, the two springs 12 rebound to return the button 4 to a state of being attached to the protective shell 5, and meanwhile, the button 4 and the elastic sheet 11 are matched to clamp the conduit and fix the conduit in the channel.

As shown in fig. 1 and 4, the device further includes a protective housing 5, and the protective housing 5 is used for clamping the first body 31 and the second body 32. The exterior of the protective shell 5 is provided with rough protrusions. When the button 4 is inserted into the rear sleeve and is sleeved with the protective shell 5, the limiting boss arranged in the middle of the button 4 prevents the button 4 from being separated from the fixer body 3. The lower part of the protective shell 5 is fixed with the boss of the fixer main body 3 by UV glue, and the protrusion arranged outside the protective shell 5 is rough, so that the friction force of the hand of a user during use is increased.
