[0003] After searching, a utility model patent with the publication number CN217634380U specifically discloses a hydraulic joint that is easy to install, including a joint body with openings at both ends, a positioning protrusion is arranged on the outer side of the joint body, a vertical positioning groove is provided on the outer surface of the positioning protrusion, a positioning rod is slidably installed in the positioning groove, a mounting hole is arranged on one side of the positioning groove, a fixing component corresponding to the positioning rod is installed in the mounting hole, a fixing plate is arranged on the outer end of the positioning rod through a positioning block, and the facing surfaces of the fixing plate and the joint body are provided with stepped threads. The above technical scheme is adopted, and the beneficial effects of the utility model are as follows: the utility model controls the fixing plate to cooperate with the joint body to clamp and fix the oil pipe under the cooperation of the positioning rod and the fixing component, and at the same time uses the stepped threads to enhance the roughness between the fixing plate and the joint body, so that the connection between the hydraulic joint and the oil pipe is more firm, and the installation is convenient and easy to disassemble.

[0004] In the above patent, the oil pipe is clamped and fixed by controlling the fixing plate to cooperate with the joint body, and the roughness between the fixing plate and the joint body is enhanced by using stepped threads, so that the connection is more firm, the installation is convenient, and the disassembly and assembly are convenient. However, during use, the sealing of the joint is extremely important, and the sealing of the joint is directly related to the performance of the hydraulic system. In the above patent, the positioning rod is only fixed in the positioning groove by pushing the handle with a spring, but the sealing of the joint cannot be guaranteed during docking, which affects the use of the hydraulic system. There is a flange docking clamping and fixing method on the market, which clamps the hydraulic joint to ensure the sealing of the joint. However, this method needs to turn the screws in sequence during installation and disassembly, which makes the installation and disassembly efficiency slow.

[0005] Therefore, it is necessary to invent a hydraulic quick-change interface clamping mechanism to solve the above problems. Utility Model Content
