The upper second transmission member 35 is in transmission connection with the first transmission member 28, and the second transmission member 35 is in transmission connection with the lock tongue 23. The third transmission member 36 is in transmission connection with the first transmission member 28 and the lower second transmission member 35.

[0029] A tail shifter 38 is slidably mounted inside the base 21 and is in transmission connection with the second transmission member 35 ;

[0030] like Figure 3 As shown, when the tail shifter 38 moves to the right, the first push piece 39 integrated with the tail shifter 38 pushes the second transmission member 35 to rotate, and the second transmission member 35 drives the lock tongue 23 to slide into the base 21 to achieve the purpose of unlocking.

[0031] In this embodiment, if Figure 1 and Figure 5 As shown, a support shaft 8 is installed inside the frame 1, and the support shaft 8 has two mounting holes. The two frames 1 can be fixed on both sides of the door using screws in conjunction with the mounting holes. The edge of the push plate 11 has a semicircular notch to facilitate screwing the screws.

[0032] In this embodiment, if Figure 5 and Figure 6 As shown, a first rotating shaft 5 is installed on the push plate 11, and the first rotating shaft 5 is rotatably connected to the frame 1. A first torsion spring 4 is sleeved on the first rotating shaft 5 to press against the frame 1. After pushing the push plate 11, the push plate 11 can be reset under the torsion of the first torsion spring 4. A decorative panel 12 can be fixed on the push plate 11. The design of the decorative panel 12 is similar to that of the door panel, and the door panel has a stronger sense of integration.

[0033] In this embodiment, if Figure 4 and Figure 6 As shown, a second rotating shaft 10 is inserted into the handle 2, and the second rotating shaft 10 is rotatably connected to the frame 1. A transmission connecting piece 9 is rotatably connected between the push hand plate 11 and the handle 2. When the first torsion spring 4 drives the push hand plate 11 to reset, the push hand plate 11 drives the handle 2 to reset through the transmission connecting piece 9.

[0034] In this embodiment, if Figure 3 As shown, two first sleeve posts 32 are installed inside the base 21, and the first transmission member 28 and the third transmission member 36 are respectively sleeved on the two first sleeve posts 32. The tail shifter 38 has a sliding hole, and the tail shifter 38 is slidably connected to the two first sleeve posts 32 through the sliding hole, thereby realizing the sliding installation of the tail shifter 38 and the base 21, ensuring that the tail shifter 38 can push the second transmission member 35 to rotate through the first push piece 39.

The push plate 11 drives the pull handle 2 to rotate through the transmission connecting piece 9. The pull handle 2 rotates and protrudes from the frame 1, becoming a handle that drives the lock tongue 23 to move.

[0037] When the handle 2 is buckled and rotated, the handle 2 pushes the tail shifter 38 to slide toward the inside of the base 21 through the pushing block 13. The tail shifter 38 pushes the second transmission member 35 to rotate around the first socket column 32 through its own first pushing piece 39. The two second transmission members 35 drive the lock tongue 23 to slide toward the inside of the base 21, and the lock is successfully unlocked. Figure 3 As shown, at the same time, the second transmission member 35 at the bottom drives the third transmission member 36 to rotate, and the third transmission member 36 drives the first transmission member 28 to rotate through the second push piece 40 (the first transmission member 28 is partially bent 90 degrees to form the second push piece 40), and the first transmission member 28 drives the upper second transmission member 35 to rotate, preparing for the tail shifter 38 to reset.

[0038] After releasing the handle 2, the first torsion spring 4 drives the push plate 11 to reset, and the push plate 11 drives the handle 2 to reset through the transmission connecting piece 9. The second torsion spring 29 pushes the second transmission member 35 to reset. The two second transmission members 35 push the tail shifter 38 to reset through the first transmission member 28 and the third transmission member 36. The spring on the lock tongue 23 pushes the lock tongue 23 to reset, thereby achieving the purpose of re-locking. Example
