[0035] Referring to Figure 2 and Figure 4The fixing mechanism comprises a sliding groove 12, which can provide good sliding ability, the outside of the sliding groove 12 is arranged in the inside of the fixing block 11, the inside of the sliding groove 12 is slidably connected with an adjusting rod 13, the adjusting rod 13 can smoothly slide in the inside of the sliding groove 12, the top of the adjusting rod 13 is fixedly connected with a supporting rod 14, which can provide good supporting ability and balance ability, the outside of the supporting rod 14 is fixedly connected with a push rod 15 on both sides, which has good pressure resistance, the outside of the two push rods 15 is fixedly connected with an inclined rod 16, which is designed to be inclined, when the push rod 15 is pressed down, the inclined rod 16 can be driven to move downward, the top of the inclined rod 16 is fixedly connected with a rotating frame 19, which can provide good angle adjustment, so that the rotating frame 19 is adjusted downward when the inclined rod 16 is pressed down, the inside of the rotating frame 19 is rotatably connected with a positioning block 17, which has good connectivity, the outside of the positioning block 17 is fixedly connected with a fixing ring 18, which is designed as two fixing rings 18, the two fixing rings 18 can fix the bending part of the connecting pipe 2 to prevent blockage caused by bending, when the push rod 15 is pressed, the supporting rod 14 is lowered, the inclined rod 16 is lowered, and the positioning block 17 in the rotating frame 19 is pulled to adjust the angle, so that the fixing rings 18 are close to each other.
[0036] Working principle: first, the operator starts the water pump 20 to start discharging the internal liquid. The output end of the water pump 20 delivers the liquid to the designated position through the connecting pipe 2. In this process, the flexible sliding of the sliding ring 3 ensures good connection between the connecting pipe 2 and the discharge mechanism. When it is necessary to fix, the operator presses the sliding ring 3, so that the clamping rod 6 opens and spreads outward. At this time, the sealing ring 10 is placed in the inside of the output end of the water pump 20, which can effectively prevent liquid leakage, and the connecting column 8 is pushed by the force applied by the spring 9, and then the clamping rod 6 is pushed. The clamping rod 6 will be firmly clamped in the output end of the water pump 20, ensuring the tightness of the connection. With the fixation of the clamping rod 6, the rotating column 5 is followed by rotation, so as to ensure that the discharge mechanism matches the connecting pipe 2 at the correct angle, after the fixation, the device enters the normal drainage working state, the water pump 20 discharges the liquid through the connecting pipe 2, and the design of the clamping rod 6 can improve the connectivity of the water pump 20 and the connecting pipe 2, ensuring the safety and efficiency of the whole unloading process;
[0037] When the connecting pipe 2 is fixed, the adjusting rod 13 is slid to the bending position of the water pipe through the sliding groove 12, and the operator presses the push rod 15. At this time, the downward pressure of the push rod 15 drives the inclined rod 16 to move downward. Due to the inclined design of the inclined rod 16, this movement causes the rotating frame 19 connected to the top of the inclined rod 16 to also adjust downward. The descent of the rotating frame 19 causes the internal positioning block 17 to move, thereby adjusting the angle. As the position of the positioning block 17 changes, the fixing ring 18 also approaches, forming a fixing effect on the connecting pipe 2. The two fixing rings 18 can effectively press the bending position of the connecting pipe 2 during the approaching process, preventing liquid flow blockage caused by bending. During the entire process, the adjusting rod 13 smoothly slides in the sliding groove 12, and the support rod 14 provides the necessary support and stability, thereby ensuring the balance and reliability of the system.
