When the drawer is pulled, the clamping claw assembly 10 and the connecting plate 12 slide along the base 11. After moving to a predetermined position, the drawer is continuously pulled to unlock and disengage the clamping portion 18 so that the drawer can be continuously pulled out. When the storage drawer needs to be pulled out, only sufficient pulling force is required to pull the storage drawer to complete the pulling out of the storage drawer. The structure is simple, and the self-locking of the storage drawer can be realized. Only sufficient pulling force is required to unlock the drawer, and the use is very convenient.

[0039] Furthermore, as a preferred embodiment, a guide groove 19 is formed on the bottom wall of the mounting groove 13, a fixing groove 20 is formed on the rear side of the connecting plate 12, a guide member 21 is provided in the fixing groove 20, and the guide member 21 can be slidably disposed in the guide groove 19.

[0040] Further, as a preferred embodiment, a connection groove 22 is provided at the front end of the connection plate 12 , a connection member 23 is provided in the connection groove 22 , and a connection column 24 is provided on the connection member 23 . The connection column 24 is connected to the clamping jaw assembly 10 .

[0041] Further, as a preferred embodiment, the guide groove 19 is formed by a combination of a plurality of horizontal segments and a plurality of vertical segments. The bottom wall of the connecting groove 22 is provided with an elongated hole 25 penetrating the connecting plate 12, the elongated hole 25 is arranged along the height direction of the connecting plate 12, and a limit block 26 is slidably arranged in the elongated hole 25, and the limit block 26 is connected to the guide member 21.

[0042] Further, as a preferred embodiment, an opening is provided on one side of the connecting member 23 close to the elongated hole 25 and a guide surface 27 is formed by cutting the side wall of the connecting member 23. The guide surface 27 cooperates with the stop block 26, thereby squeezing the stop block 26 to move upward along the elongated hole 25, so that the guide member 21 moves along the vertical section of the guide groove 19. The guide member 21 is elastic.

[0043] Specifically, in the present embodiment, a guide groove 19 is provided on the bottom wall of the mounting groove 13, and the guide groove 19 is composed of a horizontal section, a vertical section and an oblique section. A fixing groove 20 is provided on the end of the connecting plate 12 close to the guide groove 19, and a guide member 21 is provided in the fixing groove 20. The guide member 21 includes a horizontal plate portion and a compression portion. The guide member 21 has elasticity and can be compressed or rebounded. A compression portion is provided on the upper end of the horizontal plate portion, and a guide block is provided on the side of the rear end of the horizontal plate portion close to the guide groove 19. The guide block slides in the guide groove 19, thereby driving the connecting plate 12 to slide along the base 11; a limiting block 26 is provided at the other end of the horizontal plate portion, and a connecting groove 22 is provided on the end of the connecting plate 12 away from the guide groove 19. A long hole 25 is provided on the bottom wall of the connecting groove 22. The long hole 25 is provided along the height direction of the connecting plate 12, and the limiting block 26 can slide. The connecting piece 23 is provided in the long strip hole 25, and a connecting piece 23 is clamped in the connecting groove 22. A connecting column 24 is provided on the connecting piece 23, and a bolt hole is provided on the connecting column 24. The bolt passes through the bolt hole of the clamping jaw assembly 10 and is threadedly connected with the bolt hole on the connecting column 24. An opening is provided on the side of the connecting piece 23 close to the long strip hole 25, and the opening cuts the side wall of the connecting piece 23 on this side to form a guide surface 27. The guide surface 27 cooperates with the limit block 26 to push the limit block 26 to move upward. When the guide block passes through the vertical section of the guide groove 19, the storage drawer continues to be pushed. The guide surface 27 pushes the limit block 26 to move upward, thereby compressing the guide piece 21, so that the guide block also moves upward, thereby passing through the vertical section; in this way, when the storage drawer is accidentally touched, when the closing force is not reached, the vertical section cannot be passed, and the storage drawer cannot be accidentally touched and closed.

[0044] Embodiment 2:

[0045] The elastic member 31 always has a tendency to rebound inwards, and a step surface is provided on the side of the clamping portion 18 close to the opening of the upper clamping jaw 14 and the lower clamping jaw 15 for facilitating the opening of the upper clamping jaw 14 and the lower clamping jaw 15. Specifically, in this example, the elastic member 31 always has a tendency to rebound, so that the upper clamping jaw 14 and the lower clamping jaw 15 always have a tendency to move closer to each other. When the storage drawer is pulled, the upper clamping jaw 14 and the lower clamping jaw 15 are opened under the action of a strong pulling force through the interaction between the mobile connecting member 23 of the storage drawer and the step surface, so that the clamping jaw assembly 10 releases the mobile connecting member 23. When the mobile connecting member 23 moves back, the returning thrust pushes the upper clamping jaw 14 and the lower clamping jaw 15 to open them, so that the mobile connecting member 23 enters the clamping jaw assembly 10 and is clamped.

[0046] The above are only preferred embodiments of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
