[0019] According to another embodiment of the present invention, the U-shaped bracket 2 has an inward opening and is welded to the movable cover 1, and is connected to the linkage bracket 6 via a connecting pin 8.

[0020] According to another embodiment of the present invention, the push rod 7 has a U-shaped cross-section, one end is mounted on the stud of the fixed plate 4, the other end is movably connected to the linkage bracket 6, and the middle is movably connected to the push rod of the electric push cylinder 3.

[0021] According to another embodiment of the present invention, a long T-shaped pin 12 is provided through the push rod 7 and the linkage bracket 6 from top to bottom; the front end of the push rod of the electric push cylinder 3 is provided with a round hole, and is movably connected to the push rod 7 through a short T-shaped pin 13.

[0022] Specifically, the push rod 7 has a U-shaped cross-section, with one end mounted on the stud of the fixed plate 4 and the other end connected to the linkage bracket 6. A long T-shaped pin 12 passes between the linkage bracket 6 and the push rod 7 from top to bottom, allowing them to rotate flexibly.

When the moving cover 1 closes and reaches a designated position, it triggers limit switch 21, which similarly de-energizes and stops the electric push cylinder 3. The positions of the two limit switches can be adjusted according to actual needs to control the movement stroke.
