In some embodiments of the present invention, as shown in fig. 1 and 2, a first rack portion 322 extends from the lock lever 320. The first rack portion 322 is located at the opposite end of the two lock levers 320. The lower end of the upper lock lever 320 extends downward to form a first rack portion 322, and the upper end of the lower lock lever 320 extends upward to form the first rack portion 322. The first rack portions 322 of the two lock levers 320 are parallel to each other with a space therebetween. In the embodiment, the linking member 400 is in a gear shape, and the first tooth surface 321 is formed on the circumferential surface of the linking member 400. The link 400 is rotatably installed on the guide housing 310 between the two first rack portions 322. The first tooth surfaces 321 are provided on the first rack portions 322, and the first tooth surfaces 321 of the two first rack portions 322 are opposed. The second tooth surface 410 of the link 400 is engaged with the first tooth surfaces 321 on both sides. When the linkage 400 rotates, the two lock rods 320 synchronously move in opposite directions, i.e., the upper lock rod 320 moves upwards, and the lower lock rod 320 moves downwards; or the latch 320 on the upper side moves down and the latch 320 on the lower side moves up. The handle 200 may be directly connected to the link 400, and the handle 200 may be in mesh transmission with the link 400 through a gear, or the like. In this embodiment, the handle 200 acts directly on one of the locking levers 320. A first post 330 may be provided on a sidewall of the locking lever 320, the first post 330 being parallel to the rotational axis of the handle 200, the first post 330 may be integrally formed on the locking lever 320 or mounted as a component on the locking lever 320. One end of the handle 200 extending into the panel 100 is slidably connected to the first upright 330, and when the handle 200 is pulled, the handle 200 pushes the lock rod 320 to slide relative to the guide holder 310. A sliding groove may be provided at an end of the handle 200, and the sliding groove is sleeved on the first upright 330. Alternatively, the end of the handle 200 overlaps the first upright 330 corresponding to the locking lever 320 located at the upper side, when the handle 200 is pulled forward relative to the panel shell 100, the end of the handle 200 has downward pressure on the first upright 330, the locking lever 320 located at the upper side moves downward, and the locking lever 320 located at the lower side slides upward under the driving action of the linkage 400. For the return of the locking lever 320, an elastic member 500 may be provided, and the elastic member 500 is preferably a spring. The elastic member 500 may be disposed between the guide holder 310 and the lock lever 320. The elastic member 500 has an elastic force to the locking lever 320, and the elastic force has a restoring action to the locking lever 320. In this embodiment, the handle 200 applies a force to the locking bars 320 to move the two locking bars 320 relatively close to each other, so as to achieve the door/window unlocking function, and the elastic force of the elastic member 500 to the locking bars 320 is opposite to the force applied by the handle 200 to move the two locking bars 320 relatively far away to achieve the door/window locking function. Since the handle 200 can be overlapped at any position on the sidewall of the first upright 330, the installation positions of the panel 100 and the handle 200 on the door and window and the installation position of the locking piece 300 on the door and window can be adjusted according to the length of the first upright 330, and the applicability is strong.

Further, the handle 200 includes a handle portion 210 and an extension portion 220, the handle portion 210 is used as a main body of the handle 200, in this embodiment, an upper end of the handle portion 210 is rotatably connected to the face shell 100, the extension portion 220 is fixedly connected to an upper end of the handle portion 210, and the extension portion 220 rotates with the handle portion 210. The extension 220 may be in the form of a bar, slidably connected to the first upright 330, and may be overlapped on the first upright 330. The extension part 220 can extend the length of the handle 200 in the panel 100 to match the position of the lock rod 320, and the extension part 220 with different sizes can be used instead, so that the door and window installation with different sizes can be realized.

In some embodiments of the present invention, as shown in fig. 3 and 4, a linkage 400 is attached to the end of the handle 200 that extends into the panel 100. When the handle 200 rotates about the rotation axis, the link 400 rotates about the rotation axis. The second tooth surface 410 of the link 400 is formed in an arc shape facing the rear side of the face housing 100. The latch lever 320 is provided with a second rack part 323, and the second rack part 323 extends in the direction of the second tooth surface 410, that is, the second rack part 323 extends in the front-rear direction. The second rack 323 of the two latch levers 320 are parallel to each other, and the two latch levers 320 may be shifted left and right. The two second tooth-bar sections 323 are provided with first tooth flanks 321 on their sides facing the second tooth flank 410, the two first tooth flanks 321 each meshing in the same direction as the second tooth flank 410. When the handle 200 is pulled, the link 400 rotates to drive the two lock rods 320 to synchronously lift in the same direction. The locking bar 320 may be synchronously lowered as an unlocking direction and synchronously raised as a locking direction according to the installation position of the locker 300 on the door sash. On the basis of the above structure, the elastic member 500 may be installed between the locking rod 320 and the guide holder 310, and the elastic force of the elastic member 500 on the locking rod 320 is upward, that is, after the handle 200 moves the locking rod 320 in the unlocking direction, the elastic member 500 has the elastic force in the locking direction on the locking rod 320, so that the locking rod 320 automatically resets.

Further, a second upright post 340 is disposed on the sidewall of the lock lever 320, the second upright post 340 is parallel to the rotation axis of the handle 200, the second upright post 340 may be integrally formed on the lock lever 320, or may be mounted on the lock lever 320 as an independent component. A plurality of mounting holes 341 are formed in the second upright column 340, and the mounting holes 341 are distributed along the length direction of the second upright column 340, that is, along the direction of the rotation axis. The second rack may be fixed in the mounting hole 341 in an insertion manner as a separate component. According to the installation positions of the panel 100 and the handle 200 on the door and window, the installation holes 341 of the second upright 340 inserted in different positions are adjusted to match different installation sizes.
