[0028] When using the docking device for installing a gastric tube after gastrointestinal tumor surgery, the medical staff first moves the right end of the gastric tube 2 into the patient's body, and then connects the left end of the connecting tube 9 to the nursing instrument after tumor surgery. The medical staff then moves the installation sleeve 8 into the connecting sleeve 1. During the process of moving the installation sleeve 8 into the connecting sleeve 1, the right side of the connecting sleeve 1 applies an extrusion force to the wedge block 16. The right side of the wedge block 16 is designed as an inclined surface, and the left side is designed as a straight surface. The extruded wedge block 16 moves into the installation sleeve 8, and the second spring 15 is deformed, synchronously, The installation sleeve 8 applies an extrusion force to the ejector pin 12, and the first spring 13 is deformed until the ejector pin 12 contacts the limit block 14, and the wedge block 16 coincides with the limit hole 23. The second spring 15 has a rebound force, so that the wedge block 16 is inserted into the limit hole 23. The left side of the wedge block 16 is in direct contact with the limit hole 23, so that the rebound force of the first spring 13 can be avoided from squeezing the installation sleeve 8 out of the connecting sleeve 1. At this time, the wedge block 16 fixes the installation sleeve 8 in the state of being inserted into the connecting sleeve 1. The installation sleeve 8 is made of rubber material, so that the installation sleeve 8 and the connecting sleeve 1 can be sealed in a state of being connected to each other. Through the above method, a quick and convenient docking process is achieved. The medical staff then performs subsequent gastric tube treatment on the patient. After the treatment is completed, the medical staff only needs to move the conical sleeve 21 to the left along the direction of the connecting sleeve 1 by hand, and the fourth spring 22 is deformed. At this time, the conical sleeve 21 squeezes the top block 20 together with the sliding pin 18 to exert an extrusion force on the wedge block 16. At the same time, the third spring 19 is deformed, that is, the wedge block 16 is disengaged The limiting hole 23, through the action of the rebound force of the first spring 13, enables the ejector pin 12 to push the installation sleeve 8 out of the connecting sleeve 1, and the medical staff releases the conical sleeve 21 by hand, and the rebound force of the fourth spring 22 enables the conical sleeve 21 to be reset, and the squeezing force of the conical sleeve 21 on the ejector block 20 is eliminated, and the rebound force of the third spring 19 enables the ejector block 20 to drive the sliding pin 18 to be reset. It can be seen from the above that the device can not only realize the rapid docking of the gastric tube 2, but also can quickly separate the gastric tube 2 after installation.
