When the limit slider 8 slides on the inclined slide groove 603, as the position of the limit slider 8 is lowered, the distance between the two groups of limit sliders 8 is As the position of the limit slider 8 is higher, the spacing between the two groups of limit sliders 8 is smaller, thereby clamping and fixing the action rod 3 in the through hole 602; a groove 604 is fixedly provided on the upper part of the inclined slide 603, the bottom of the groove 604 is connected to the inclined slide 603, and the groove 604 extends upward to the top of the adjustment seat 6, the groove 604 cooperates with the pull rod 9, and the pull rod 9 moves in the groove 604 to pull the limit slider 8; a limit squeeze block 601 is fixedly provided on the top of the adjustment seat 6.

[0030] like Fig.10 As shown, a pressure head 301 is fixedly arranged at the bottom of the action rod 3, and a locking column 302 is fixedly arranged at the top of the action rod 3. Since different types of wiring harness terminals require different action rods 3 to be pushed out, there are various types of action rods 3, with different rod diameters and different shapes of pressure heads 301. It is only necessary to set a locking column 302 at the top of the action rod 3, so that various types of action rods 3 can be quickly installed on the device, and the action rod 3 can be quickly disassembled and installed.

[0036] 4. Release the pressing handle 2, and the transmission pressing rod 4 moves upward under the elastic force of the pressing spring 5, driving the limit slider 8 to shrink toward the center, driving the gusset plate 7 to leave the limit squeeze block 601, and the gusset plates 7 shrink closer to each other under the torsion force of the torsion spring 10;

[0037] 5. The limit slider 8 squeezes the rod body of the action rod 3, and the top of the gusset plate 7 locks the lock column 302, completing the rapid installation of a set of action rods 3;

[0038] 6. When the action rod 3 needs to be disassembled, press the pressure handle 2 again to withdraw the action rod 3.

[0039] The utility model is provided with a transmission pressure rod 4, a pull rod 9 and a limit slider 8. When the action rod 3 is placed inside the mounting shell 1, the transmission pressure rod 4 moves upward under the push of the compression spring 5, driving the limit slider 8 to move toward the middle, squeezing the outer wall of the action rod 3, and fixing the action rod 3. By providing a torsion spring 10 and a gusset plate 7, the tops of the two groups of gusset plates 7 keep a tendency to approach each other on the rotating rod 403A. At this time, the tops of the gusset plates 7 are inclined toward the center, and the bottoms of the gusset plates 7 are inclined toward the outside. The tops of the gusset plates 7 will clamp the lock column 302, so that the action rod 3 is locked.
