[0041] The fixing assembly 3 is arranged at one end of the mounting groove 21 away from the first sealing gasket 22, and includes a pressing block 31 and a mounting frame 32. The pressing block 31 is arranged on the outer side of the mounting groove 21. One end of the pressing block 31 away from the first sealing gasket 22 is fixedly connected to a supporting slider 33 extending into the mounting groove 21. One end of the mounting groove 21 away from the first sealing gasket 22 is provided with a first screw hole 24, and the first screw hole 24 is threadedly connected with a first screw 34. The bottom frame of the mounting frame 32 is slidably embedded in the first through groove 23. The mounting frame 32 is provided with a second screw hole 35 on the outer side of the pressing block 32, and the second screw hole 35 is threadedly connected with a second screw 36. A plurality of pressing blocks 31 are provided for replacement use, and different pressing blocks 31 are provided with coaxial third screw holes 37 corresponding to the spray holes 63 on different spray bars 6 respectively.

[0042] The test assembly 4 is installed on the pressing block 31 and is used to collect the test medium sprayed from the spray hole 63 for flow test and to block the spray hole 63 for sealing test;

[0043] The adapter assembly 5 is fixedly arranged on the base 1 in an adjustable position, and is used for connecting the oil inlet end 65 of different spray bars 6 to the tester through position adjustment.

[0044] In this embodiment, when the performance of the spray rod 6 is tested, firstly, a pressure block 31 matching the position of the spray hole 63 is selected for standby according to the structure of the spray rod 6, and then the first rod body 61 of the spray rod 6 is embedded in the installation groove 21, and the connecting hole 64 is pressed against the first sealing gasket 22 for blocking; then the pressure block 31 is placed on the outside of the first rod body 61, and the support slider 33 is embedded in the installation groove 21 and pressed against the end of the first rod body 61 away from the first sealing gasket 22; then the bottom frame of the installation frame 32 is slid and inserted into the first through groove 23, and then the first screw 34 and the second screw 36 are tightened respectively to fix the spray rod 6. The pressure block 31 and the support slider 33 cooperate to fix the spray rod 6 without being affected by the length of the first rod body 61, and have good adaptability and good fixing effect.

[0045] Then adjust the position of the adapter assembly 5, align it with the oil inlet end 65 of the spray rod 6, and connect the oil inlet end 65 to the tester through the adapter assembly 5; then install the test assembly 4 on the pressing block 31 to perform flow test and sealing test respectively; the clamping tooling of the present application realizes the performance testing of various spray rods 6 with similar structures, with convenient operation, high testing efficiency and accurate testing, thereby ensuring the processing quality of the spray rod 6.
