The technical solution and the advantages of the present invention will be more clear and clear by further describing the embodiments of the present invention with reference to the accompanying drawings.

Referring to the drawings 1 to 6, the utility model discloses a lock body 3 of preceding lock box 1, back lock box 2 and between lock box 1 and back lock box 2 before establishing is equipped with preceding handle 4 on the preceding lock box 1, is equipped with back handle 5 on the back lock box 2, its characterized in that: a gear set 6 for reducing the speed and superposing is arranged in the lock body 3, and the gear set 6 comprises a driving gear 601, a first reduction gear 602, a second reduction gear 603 and a bolt gear 604 which are arranged in a meshing sequence from bottom to top;

the latch bolt gear 604 comprises a latch hook 605 arranged on the left side and a limit block 606 arranged on the right side, the hook opening direction of the latch hook 605 is upward, a driving tooth 607 is arranged on the downward side between the latch hook 605 and the limit block 606, and a limit vacancy 608 is arranged between the driving tooth 607 and the limit block 606.

The limit clearance portion 608 can prevent the latch bolt gear 604 from rotating excessively when rotating clockwise, and the limit clearance portion 608 and the second reduction gear 603 can prevent the force of the second reduction gear 603 from being transmitted to the latch bolt gear 604. Meanwhile, the second reduction gear 603 can be engaged with the driving gear 607 when the direction is reversed.

The side surface of the latch bolt gear 604 facing the second reduction gear 603 is provided with a concave adapting platform 609, and the adapting platform 609 is matched with the second reduction gear 603;

adapter 609 spans over from lock hook 605 and stop 606, and adapter 609 occupies more than or equal to 50% of the side.

Further, a limit switch 7 is arranged on the right side of the bolt gear 604, the limit switch 7 is matched with the limit block 606, and the limit switch 7 is located above the limit block 606.

When the limit block 606 touches the limit switch 7, the speed reducing motor 9 is powered off and stops working,

further, a first square hole 6010 is formed in the center of the driving gear 601, a first square shaft 8 is arranged on the first square hole 6010, a speed reduction motor 9 is arranged at the front end of the first square shaft 8, and the speed reduction motor 9 is arranged in the front lock box 1.

Further, a transmission member 10 is arranged between the speed reduction motor 9 and the first square shaft 8, the transmission member 10 is tubular, a second square hole 1001 matched with the first square shaft 8 is arranged in the transmission member 10, and a plurality of transmission blocks 1002 are arranged on the outer side of the transmission member 10.

Furthermore, a transmission hole 901 matched with the transmission part 10 is formed in the speed reducing motor 9, and a transmission groove 902 matched with the transmission block 1002 is formed in the transmission hole 901.
