The front of the connecting frame 201 is processed with a plurality of slide grooves 202. The inner wall of the slide groove 202 is slidably connected with a straight cylinder 203. The straight cylinder 203 is subjected to force to slide along the inner wall of the slide groove 202. A first round opening 204 is processed on the upper left side of the front of the connecting frame 201. The inner walls of the straight cylinder 203 and the first round opening 204 are both processed with threads.

[0022] Through the installation structure 2, the rear of the connecting frame 201 is made to fit with the front of the chassis 1, and then the second bolt 8 passes through the first circular opening 204 and is threadedly connected with the corresponding second circular opening 4. Then the straight cylinder 203 slides on the inner wall of the slide groove 202, and the position of the straight cylinder 203 is adjusted to align the inner wall of the straight cylinder 203 with the corresponding second circular opening 4. Then the second bolt 8 passes through the straight cylinder 203 and is threadedly fixed with the inner wall of the second circular opening 4 to complete the fixation of the chassis 1 and the connecting frame 201, ensuring the normal installation of the portable assembly pump head tooling and the use of the portable assembly pump head tooling.
