DESCRIPTION Locking mechanism for drawers TECHNICAL FIELD The present invention relates to a locking device, in particular a drawer stop 5 automatic slide drawers with anti-skid function of the locking mechanism. BACKGROUND OF THE INVENTION In some current flow toolbox with drawers lockers, motor vehicles, desk used, as in the non-locked state can be freely pulled out and easy to use, but the anti-shake or vibration capability of this drawer is poor, easy slide, poor safety performance. In .0 order to improve work safety drawer, existing technology usually requires locking a drawer, and a key to open, resulting in inconvenience during use. Recent products on the market include drawer locking mechanism with a key, but there are some problems in the actual production and use. For example: Application No. CN 201020289422.2 utility model patent discloses a novel slip out of the drawer locking 15 mechanism that by setting the mounting holes on the drawer panel, shackle through the mounting hole assembly. This kind of design approach has the flaw on the following aspects: Firstly, the dimensional accuracy of the welded shackle boards and drawer handles must be exactly aligned on the detent assembly through mounting holes, must request the shackle and drawer handles board after soldering 20 through the mounting holes, if there is deviation weld size, it will result in the shackle and mounting hole cannot just meet, leading to installation difficulties, or need to re adjust the latch hook and drawer handles welded plate size. Second: the installation process is complex, the locking mechanism of the ways to set up first need to handle 1 and latch hook installed, and then through the mounting holes for installation, of the mounting holes the right size, but also the need for additional adjustments. Third: If there is defective after installation is complete, it will lead to the fold against the handle, which leads to difficulty in opening of the drawer. 5 SUMMARY The present patent application is designed to solve the above problems and to provide a non-slip out of the drawer locking mechanism, especially a convenient installation, labor cost optimization slip out of the drawer locking mechanism. To achieve the above object, the present model slip out of the drawer locking .0 mechanism, including the handle 10, the locking hook 10 with the lever 20 connected to the handle, and with the shackle 20 with tabs to lock or open drawer 30, said shackle stopper plate 20 is rotatably mounted on the stopper plate 40, the vertical and 40 fixedly connected with the drawer panel 50 and 60 respectively on the drawer flap. .5 Further, the shackle 20 of one or two, said stopper plate 40 is provided corresponding to one or two. Further, the drawer panel 50 are cut off on one or two corners, set aside one or two can accommodate shackle recess 20 after the lock hook 20 is mounted in the groove. 20 Further, the bottom 20 of the shackle 21 is provided with barbs, the barbs 21 and the spring 70 together provide a reactive force to the handle 10. 2 The utility of new contribution is provided by a slip out of the drawer locking mechanism, the detent mechanism set up the panel in a drawer or corner side groove, the installation process is simple, labor cost optimization, greatly reduced installation difficulty. And the model is not easy to use a non-slip drawer locking 5 mechanism for locking hook and the angle formed by the handle low accuracy requirements, it will not cause the latch hook is not installed or installed after the situation. In addition the invention provided a slip out of the drawer locking mechanism, whether in use or during transport structures are very stable, long life. In material cost less compared to other locking mechanism, reducing the company's .0 production costs. BRIEF DESCRIPTION FIG. 1 is the invention shackle mounted on the side of the exploded view of the drawer panel FIG. 2 is an exploded view of the invention shackle mounted in the recess of the .s drawer panel FIG. 3 is the invention as a shackle exploded view FIG. 4 is a schematic structural view of the invention, the installation is complete shackle hook fixed pieces FIG. 5 is a block diagram of the invention after the installation is complete release 20 the fixing piece of the shackle 3 DETAILED DESCRIPTION The following examples are illustrative of the invention is further explained and added that for the invention does not constitute any restrictions. Example 1 5 As shown in Fig 1,4,5, drawers of the present embodiment includes a non-slip handle 10 of the locking mechanism, the lock claw 10 and the lever 20 connected to the handle, and to cooperate with the locking hook 20 to lock or open the drawer fixing piece 30, the shackle 20 is rotatably mounted on the stopper plate 40, said stopper plate 40 are perpendicular to the fixed panel 50 connected with the drawer .0 60 and the drawer hemming. This kind of connection of the present embodiment, the drawer 50 is connected with the folding panel 60 is fixed on a vertical drawer, a 7-shaped form, the stopper plate 40 respectively on the drawer and drawer panel 50 vertically fixed and folding to form the corner of a cube, the stopper plate 40 so that a stable structure does not appear to rotate or fall situation. Shackle 20 connected .s through a hollow shaft rotatably mounted on the stopper plate 40, an upward pulling force is applied to the handle 10, the lock claw 20 and the fixing piece 30 separated under leverage, then the drawer can be pulled out; When not pulling force to the handle 10, the locking hook 30 engages with the fixing piece, to achieve the purpose of locking the drawer. This kind of design easy accessibility, optimize labor costs, to 20 make the shackle 20 less precision, but also can save material costs. Example 2 As shown in Fig 2, 4, and 5, drawers of the present embodiment includes a non-slip handle 10 of the locking mechanism, the lock claw 10 and the lever 20 connected to 4 the handle, and to cooperate with the locking hook 20 to lock or open the drawer fixing piece 30, the shackle 20 is rotatably mounted on the stopper plate 40, said stopper plate 40 are perpendicular to the fixed panel 50 connected with the drawer 60 and the drawer hemming. The drawer panel 50 are cut off on one or two corners, 5 set aside one or two grooves can accommodate shackle 20, after the lock hook 20 is mounted in the groove. In this embodiment, the hook lock 20 is disposed in the recess, the invention can compact structure, do not take up extra space and elegant appearance. Example 3 .0 As shown in Figure 3, 4, in the present embodiment, on the basis of Example 2 was change, the number of the lock claw 20 is set to a, and the fixing plate 30 is also provided only one, the only way can achieve the above functions of the embodiments, the structure is stable, easy to use, while reducing timber. Example 4 .5 As shown in Fig 4 and 5, in the present embodiment, on the basis of Example 3 were changes, the number of the lock claw 20 is set to two, and the two fixing pieces 30 are provided, said additional locking the bottom 20 is provided with a barbed hook 21, the barbs 21 and spring 70 together provide a reaction force to handle 10. The spring 70 is always present embodiment provides tension to the barbs 21, the lock 20 hooks 20 a pulling force in the period of non-snapping fixing piece 30, to achieve the purpose of locking the drawer. Although the above embodiments of the present invention has been revealed, but the scope of protection of the invention is not limited thereto without departing from 5 the idea of the condition of the invention, deformation made the above components, replacement, etc. They are within the scope of the claimed invention fall within this requirement. 6
