An opening rocker arm, a lever, a lock leaf, a locking piece and a retaining rod are movably arranged on the cover plate. One end of the opening rocker arm is hinged with a transmission shaft, and the upper end of the transmission shaft is hinged with the second handle. The lock leaf is equipped with a first torsion spring to urge it to rotate counterclockwise. The locking piece is equipped with a second torsion spring to urge it to rotate counterclockwise. The lever is equipped with a third torsion spring to urge it to rotate counterclockwise, and the lever and the warning block are connected by a fourth torsion spring. The warning block is movably passed through the handle seat through the fourth torsion spring and linked with the lever. The retaining rod is equipped with a fifth torsion spring to urge it to rotate counterclockwise.

[0006] Further, a first rivet, a second rivet and a third rivet are arranged on the cover plate. The opening rocker arm, the lever and the third torsion spring are sleeved on the first rivet. The lock leaf, the locking piece, the first torsion spring and the second torsion spring are sleeved on the second rivet. The retaining rod and the fifth torsion spring are sleeved on the third rivet.

[0007] Further, a fourth rivet and a column that can abut against the lever are arranged on the lock leaf. An arc-shaped through hole for inserting and moving the fourth rivet is arranged on the locking piece, and a baffle for blocking the other end of the opening rocker arm is arranged on the locking piece. A retaining piece for blocking the lock leaf is arranged on the retaining rod.

[0008] Further, the second handle includes an upper cover and a lower cover, and the upper cover and the lower cover are detachably connected by a plurality of screws.
