Specifically, the latch member 6 has a latch plate 61 and a release lever 62, the latch plate 61 being movably connected to the first member 4 or the second member 5 or other support object. The release lever 62 is located between the shift lever 2 and the release lever 62. The locking plate 61 is connected to the first member 4 or to the second member 5 when locked. Taking the example of the locking plate 61 locking the first member 4, the first member 4 is provided with a connecting position. When the lock plate 61 locks the first member 4, the lock plate 61 is connected to the connection to immobilize the first member 4. When the deviation rod 2 is pushed by the push rod 1 to move towards the second direction and is guided to deviate by the guide piece 3, the unlocking part 23 is connected with the release rod 62, and drives the release rod 62 to move. The release lever 62 moves the lock plate 61 away from the connection position, and releases the lock of the first member 4.

Alternatively, in other embodiments, the locking member 6 is formed by a locking plate 61, and the locking plate 61 locks the first member 4 and the second member 5. The locking plate 61 is connected to the unlocking portion 23 and is moved by the unlocking portion 23. For example, the locking plate 61 is slidably connected to the first member 4, the locking plate 61 has a pin on the end facing the second member 5, and the second member 5 has a hole. When locking, the locking feet of the locking plate 61 are inserted into the buckling holes. When the unlocking part 23 drives the locking plate 61 to move towards the second direction, the button foot is separated from the button hole, and unlocking is realized.

In one embodiment, as shown in fig. 2 to 6, the release lever 62 is provided with a release portion 621 for abutting against the unlocking portion 23, the release portion 621 has an abutting surface 6211 and a non-abutting surface 6212 opposite to the abutting surface 6211, and the unlocking portion 23 is located on one side of the non-abutting surface 6212 in the initial state. When the guide end 22 moves in the third direction, the unlocking portion 23 moves away from the releasing portion 621 to the side of the contact surface 6211 of the releasing portion 621. When the guide end 22 moves in the fourth direction, the unlocking portion 23 approaches the releasing portion 621 until it comes into contact with the contact surface 6211, and the releasing portion 621 is moved in the second direction.

Specifically, the release lever 62 is provided with a release portion 621 extending toward the unlocking portion 23. The release portion 621 has an abutment surface 6211 and a non-abutment surface 6212, and the non-abutment surface 6212 is positioned above the abutment surface 6211. In the initial state of the shift lever 2, the unlocking portion 23 is located on the side of the non-abutment surface 6212, i.e., closer to the non-abutment surface 6212. When the guide end 22 moves from the first end 3111 to the second end 3112 of the first guide groove 311, that is, in the first direction, the unlocking portion 23 moves closer to the contact surface 6211 and is displaced from the releasing portion 621. And when the guide end 22 passes the first step 32, the unlocking portion 23 moves to overlap with the releasing portion 621 at least partially. Then, when the guide end 22 moves from the third end portion 3121 to the fourth end portion 3122, the unlocking portion 23 is moved upward by the biasing rod 2. At this time, the unlocking portion 23 contacts the abutment surface 6211 and pushes up the releasing portion 621, and the releasing lever 62 is moved upward, thereby moving the locking plate 61.

Alternatively, the end of the lock plate 61 contacting the release lever 62 is a slope, and when the release lever 62 moves upward, the release lever 62 pushes the lock plate 61 to move laterally.

In one embodiment, as shown in FIGS. 1-4 and 10, the locking member 6 is movably coupled between the first member 4 and the second member 5. The first member 4 or the second member 5 is provided with a projection 7, and the locking member 6 locks the first member 4 and the second member 5 by stopping. When the push rod 1 moves towards the second direction, the unlocking part 23 drives the locking piece 6 to leave the lug 7, and the limitation on the first component 4 and the second component 5 is released.

Taking the first member 4 provided with the projection 7 as an example, the first member 4 and the second member 5 are rotatably connected by a connecting shaft. The locking plate 61 is slidably connected to the connecting shaft, and when the locking plate 61 locks the first member 4, a portion of the locking plate 61 is located on the projection 7 and blocks the projection 7, thereby restricting the rotation of the first member 4. When the release lever 62 pushes the lock plate 61 away from the projection 7, the lock plate 61 is separated from the projection 7, releasing the projection 7 from the blocking, allowing the first member 4 to be rotated again.

In one embodiment, as shown in fig. 1-4 and 7-10, the unlocking structure 10 further comprises a linkage locking member 9 capable of locking the third component 8, wherein the linkage locking member 9 is positioned on one side of the projection 7. The convex block 7 is provided with a pushing part 71, when the locking piece 6 is unlocked, the pushing part 71 pushes the linkage locking piece 9, so that the linkage locking piece 9 unlocks the third part 8.

Specifically, the device further comprises a third component 8 and a linkage locking piece 9, wherein the linkage locking piece 9 comprises a linkage rod 91 and a locking plate 92. Locking plate 92 is located to one side of boss 7 and linkage rod 91 is located between locking plate 92 and boss 7.
