[0020] Now, the structure and use of the utility model are further described in combination with the drawings. Figures 1-7As shown, the handle 1 of the handle device is provided with a lock cylinder slot hole 101 at one end, a lock cylinder assembly is arranged in the lock cylinder slot hole of the handle, the other end of the handle is fixed in the handle slot of the base below the handle through a rotating shaft, a sliding cover 3 is arranged above the lock cylinder slot hole of the handle, the cover openings on both sides of the sliding cover are slidably embedded in the corresponding guide edges or guide grooves of the handle, and the key hole of the lock cylinder assembly is exposed or closed through the sliding of the sliding cover. Further, the cover openings on both sides of the sliding cover are symmetrically provided with a one-character-shaped slot 301, the handle is provided with a fixed piece hole 102 corresponding to the slot on both sides of the handle, and the fixed pieces 401 extended from the fixed piece holes on both sides of the handle are respectively inserted into the slots on both sides of the sliding cover, the fixed pieces are extended from the fixed piece holes on both sides of the handle through the action of the springs 402 therebetween, and the ends of the slots of the sliding cover are respectively provided with limiting plugs.

[0021] The fixed pieces and the springs are encapsulated in the mounting grooves on the top or bottom of the handle through a cover plate 403 and a screw 404, the fixed pieces on both sides of the cover plate are extended through the action of the springs and extended from the fixed piece holes of the handle, and the fixed pieces, the springs, the cover plate and the screw form an elastic fixing assembly 4. The sliding cover is a metal sliding cover, and the limiting plugs at one end of the slots on both sides of the metal sliding cover are respectively provided with limiting pins 2 punched into the corresponding slots.

[0022] The core structure of the handle device includes a metal sliding cover, a handle side wall, an elastic fixing assembly and a locking assembly. The metal sliding cover is made of light and high-strength metal materials such as zinc alloy, aluminum alloy and stainless steel, and anti-slip lines are added on the surface as needed. The handle side wall is provided with a guide edge or a guide groove corresponding to the handle side wall on both sides of the sliding cover, a sliding track (such as a T-shaped or dovetail groove structure) is arranged in the guide groove, the guide edge limits the sliding cover from falling out and facilitates the sliding of the sliding cover, the elastic fixing assembly includes fixed pieces, springs, a cover plate and a screw, one end of the fixed pieces on both sides of the elastic fixing assembly is connected to the handle through the springs, the other end of the fixed pieces is embedded in the slot of the sliding cover, and the elastic compensation required for the sliding of the sliding cover is provided through the deformation of the springs. Figure 8 As shown, further, the locking assembly is provided with a buckle groove at the end of the sliding cover, the buckle groove is provided with an elastic buckle button 5 corresponding to the position of the handle, and secondary locking after the sliding cover is closed is realized; that is, when the sliding cover is slid to close the key hole of the lock cylinder assembly, the elastic buckle button locks the buckle groove of the sliding cover; or one end of the slot of the sliding cover is provided with a limiting hole, and when the sliding cover is slid to close the key hole of the lock cylinder assembly, the fixed piece is clamped into the limiting hole of the sliding cover.
