The hydraulic quick-connect fitting can be quickly connected and disassembled, reducing the downtime.

[0004] The connection force of a hydraulic quick-connect fitting refers to the force that needs to be overcome during the connection process of the hydraulic quick-connect fitting, and the disconnection force refers to the force that needs to be overcome during the disconnection process of the hydraulic quick-connect fitting. These two forces are important indicators for evaluating the performance of a hydraulic quick-connect fitting. When testing the connection force and disconnection force, due to the different sizes of the two parts at the connection of the hydraulic quick-connect fitting, it is difficult to align the axes during clamping and fixing, making it difficult to test the connection force. In view of this, this application proposes a testing device for the connection force and disconnection force of a hydraulic quick-connect fitting. Content of the Utility Model
