[0031] Auxiliary hook beam 27 and main hook beam 33, the auxiliary hook beam 27 and main hook beam 33 are respectively connected to the pushing mechanism of the auxiliary hook main shaft 22 and the main hook main shaft 9, the auxiliary hook frame 31 and the main hook frame 34 are respectively arranged on the auxiliary hook beam 27 and the main hook beam 33, and the auxiliary hook 32 and the main hook 37 corresponding to the position are respectively arranged at the front of the auxiliary hook frame 31 and the main hook frame 34;

[0032] Two linear bearing seats 16 are arranged in parallel, a transverse axis 18 is connected between the two linear bearing seats 16, a pushing mechanism between the auxiliary hook beam 27 and the auxiliary hook main shaft 22 is connected to the transverse axis 18, a transverse axis fixing seat 17 is arranged on the outer side of the two linear bearing seats 16, and the transverse axis fixing seat 17 is connected to the end of the transverse axis 18, a transverse push rod fixing plate 19 is arranged on the side wall of one of the transverse push rod fixing seats 17, a transverse push rod 15 is fixedly connected to the transverse push rod fixing plate 19, the transverse push rod 15 is mounted on a mounting plate, a linear bearing 14 matched with the transverse push rod 15 is arranged on the mounting plate, and the transverse axis 18 and the auxiliary hook main shaft 22 are movably connected to the linear bearing seat 16 through a linear bearing 2 5;

[0033] A rotating and swinging mechanism is arranged outside one side of the two linear bearing seats 16, and a telescopic spring 42 connected to the transverse shaft 18 is arranged outside the other side of the two linear bearing seats 16. The rotating and swinging mechanism is connected to the auxiliary hook main shaft 22, the main hook main shaft 9, and the transverse push rod 15. The rotating and swinging mechanism is used to drive the auxiliary hook main shaft 22 and the main hook main shaft 9 to rotate, and the rotating and swinging mechanism is used to push the transverse push rod 15 and the transverse shaft 18 to move.

[0034] When in use, the transverse push rod 15 is pushed by the rotating and swinging mechanism, so that the transverse axis fixing seat 17 and the transverse axis 18 are pushed laterally, and at the same time the telescopic spring 42 is compressed. When the rotating and swinging mechanism retracts, the telescopic spring 42 pushes the transverse axis fixing seat 17 and the transverse axis 18 back, so that the auxiliary hook frame 31 and the auxiliary hook 32 move left and right relative to the main hook frame 34 and the main hook 37.
