A transmission part 2 is provided between the top and bottom hook 1 3 and the top and bottom hook 2 4. When the top and bottom hook 1 3 translates, the top and bottom hook 2 4 is driven to translate synchronously in the opposite direction through the transmission part 2. When the top and bottom hooks 1 3 and 2 4 translate, they respectively drive the lock tongue 2 6 and the lock tongue 1 5 to rotate synchronously, so that the lock tongue 1 5 and the lock tongue 2 6 are rotated out of the lock body 1 or rotated back into the lock body 1 to realize locking or closing correspondingly.

[0027] like Figure 3 and Figure 5As shown, the transmission member 1 includes a lever 7, one end of which is fixedly connected to the handle 2, and a convex shaft 8 is fixedly arranged on the other end thereof. The top hook 1 3 is provided with a shifting groove 9, and the convex shaft 8 is embedded in the shifting groove 9. The handle 2 drives the lever 7 to rotate synchronously, so that the convex shaft 8 drives the top hook 1 3 to translate along the shifting groove 9. The transmission member 2 includes a gear 10 rotatably arranged on the lock body 1, and the top hook 1 3 and the top hook 2 4 are both provided with a rack 11, and the two racks 11 are arranged on both sides of the gear 10. When the top hook 1 3 translates, the gear 10 is driven to rotate, and the gear 10 drives the top hook 2 4 to translate synchronously in the opposite direction.

[0028] The handle 2 drives the top hook 3 to translate through the lever 7, and the top hook 3 drives the top hook 2 4 to translate through the gear 10 and the two racks 11. The translation of the top hook 3 and the top hook 2 4 respectively drives the lock tongue 2 6 and the lock tongue 1 5 to rotate to realize unlocking and locking.

[0029] like Figures 3 to 6 As shown, a guide groove 18 is provided on the top hook 3, a guide column 19 is fixed on the lock tongue 6, the lock tongue 6 is rotatably arranged on the lock body 1 through a center column 20, the guide column 19 is embedded in the guide groove 18, when the top hook 3 is translated, the guide column 19 rotates around the center column 20 along the guide groove 18. A guide groove 21 is provided on the top hook 4, a guide column 22 is fixed on the lock tongue 5, the lock tongue 5 is rotatably arranged on the lock body 1 through a center column 23, the guide column 22 is embedded in the guide groove 21, when the top hook 4 is translated, the guide column 22 rotates around the center column 23 along the guide groove 21.

A transmission member three is provided between the keyhole 12 and the limit block 13. The key is inserted into the keyhole 12 to rotate the keyhole 12 and drive the limit block 13 to translate through the transmission member three; when the lock tongue extends out of the lock body 1, the keyhole 12 is rotated to make the limit block 13 move to a position corresponding to the lock tongue. When unlocking, the lock tongue can be blocked by the limit block 13 to limit the lock tongue from retreating into the lock body 1 to form a locked state; the key is rotated in the opposite direction to make the limit block 13 away from the lock tongue to form an unlocked state.

[0031] The limit block 13 is fixed on a limit plate 14, which is slidably set on the lock body 1, and the sliding direction of the limit piece is parallel to the sliding direction of the top and bottom hooks; the lock tongue has a supporting surface 15 on the side facing the limit block 13. When the lock tongue extends out of the lock body 1, the key hole 12 is rotated to make the position of the limit block 13 correspond to the supporting surface 15 to form a locked state, and the key is rotated in the opposite direction to make the limit block 13 away from the supporting surface 15 to form an unlocked state.

[0032] The transmission member 3 includes a shift block 16 fixedly connected to the keyhole 12. Two protrusions are fixedly provided on the limit plate 14. The shift block 16 is located between the two protrusions. Rotating the keyhole 12 drives the shift block 16 to rotate synchronously, so that the shift block 16 rotates to abut against one of the protrusions and pushes the limit block 13 to translate.
