One end of the lead screw shaft 22 is fixedly connected to a lock block 23, and the other end is fixedly connected to a second handle 26. A third handle 27 is hinged on the second handle 26. A torsion spring 28 is installed inside the second handle 26, and one end of the torsion spring 28 is arranged on the third handle 27, and the other end is arranged on the second handle 26. A latch 29 is hinged on the third handle 27, and the latch 29 is slidably connected to the second handle 26. A housing 210 is arranged outside the second handle 26, and the housing 210 is fixedly connected inside the oven body 1. The latch 29 is clamped on the housing 210, and the latch 29 is used to lock the second handle 26 on the housing 210. The second handle 26 is used to drive the lead screw shaft 22, and the lead screw shaft 22 drives the lock block 23 to deflect, so as to achieve unlocking. The torsion spring 28 is used to provide a reset elastic force for the third handle 27, and the third handle 27 is used to drive the latch 29, so that the latch 29 is unlocked from the housing 210; A sleeve 24 is sleeved on the lead screw shaft 22, and the sleeve 24 is fixedly connected to the second handle 26. A locking member 25 is fixedly connected to the sleeve 24, and the locking member 25 is arranged on one side of the lead screw shaft 22. The sleeve 24 cooperates with the locking member 25 to achieve the fixed connection between the lead screw shaft 22 and the second handle 26; A first door 11 is hinged on the oven body 1. A second door 12 is arranged on one side of the first door 11, and the second door 12 is hinged on the oven body 1. A first connecting shaft 14 is hinged on the second door 12. The top of the first connecting shaft 14 is fixedly connected to an eccentric block 17. A fixing rod 18 is fixedly connected to the eccentric block 17, and the fixing rod 18 is arranged on one side of the lock block 23. The first door 11 and the second door 12 are used to close the oven body 1. The first connecting shaft 14 is used to drive the eccentric block 17, and the eccentric block 17 achieves locking with the lock block 23 through the fixing rod 18; Hinges 13 are fixedly connected to both the first door 11 and the second door 12, and the hinges 13 are fixedly connected to the oven body 1. The hinges 13 are used to achieve the hinge between the first door 11 and the oven body 1, and are used to achieve the hinge between the second door 12 and the oven body 1; A plurality of mounting seats 15 are hinged on the first connecting shaft 14, and the mounting seats 15 are fixedly connected to the oven body 1.

The second handle 26 drives the lead screw shaft 22, and the lead screw shaft 22 rotates in the shaft seat 21. The lock block 23 on the lead screw shaft 22 rotates 90 degrees, and the lock block 23 disengages from the fixing rod 18. Since the fixing rod 18 loses the locking, the second door 12 can be pushed open from the inside of the oven body 1; among them, the first door 11 is limited by the second door 12. The hinge 13 is used to realize the hinge between the first door 11 and the oven body 1, and to realize the hinge between the second door 12 and the oven body 1. The mounting seat 15 is used to mount the first connecting shaft 14. The shaft sleeve 24 cooperates with the locking member 25 to fix the lead screw shaft 22 on the second handle 26. The card slot of the housing 210 is not shown in the figure. The cooperation between the bolt 29 and the card slot is a prior art, so it will not be described in detail.
