     DETAILED DESCRIPTION OF THE INVENTION 
     The technical solutions in the embodiments of the invention are clearly and completely described in combination with the drawings in the embodiments of the invention. Obviously, the described embodiments are only a part but not all of the invention. Based on the embodiments of the invention, all other embodiments obtained by any ordinary technician in the art without any creative work shall fall within the protection scope of the invention. 
     Referring to  FIGS.  1  to  7   , a storage container of the invention comprises a slide frame  1  and a drawer  2  movably disposed in the slide frame  1 . The slide frame  1  comprises a bottom plate  11 , at least one column  13  and a top plate  12 . The column  13  is disposed between the bottom plate  11  and the top plate  12 , the opposite sides of the bottom plate  11  and the top plate  12  are provided with insertion grooves  14 , and one side of the inner wall of each insertion groove  14  is provided with a clamping groove  15 . Clamping plates  131  are disposed at the top end and bottom end of the column  13 , the ends of clamping plates  131  far away from the column  13  extend into the insertion grooves  14 , and the clamping plates  131  are also provided with clamping blocks  132  connected to the clamping grooves  15 . 
     A positioning enclosure  112  is disposed on the bottom of the bottom plate  11  , and a positioning groove  122  matching the positioning enclosure  112  for stacking two slide frames  1  is disposed on the top of the top plate  12 . 
     A slide rail  114  is disposed on the top of the bottom plate  11 , a slide rod  21  matching the slide rail  114  is disposed on the bottom of the drawer  2 , and the slide rod  21  is movably disposed in the slide rail  114 , so that the slide rod  21  can only slide along the track of the slide rail  114 . 
     As a specific technical solution of the embodiment, a reinforcing enclosure  23  is disposed on the top of the drawer  2 , a handle  24  is disposed on one side of the reinforcing enclosure  23 , and the drawer  2 , the reinforcing enclosure  23  and the handle  24  are integrally formed. The reinforcing enclosure  23  effectively improves the structural strength of the opening of the drawer  2 , avoiding cracks and damages. The handle  24  disposed in an arc shape is beautiful and comfortable to hold. The drawer  2 , the reinforcing enclosure  23  and the handle  24  are integrally formed, further ensuring the structural strength. 
     As a specific technical solution of the embodiment, at least one hollow groove  113  is disposed at the bottom of the bottom plate  11 , and at least one abrasive strip II  22  is disposed at the bottom of the drawer  2  to increase the friction between the bottom of the drawer  2  and the top of the bottom plate  11 . The hollow groove  113  saves the raw materials for processing the bottom plate  11 , and is conducive to releasing the stress generated during the forming of the bottom plate  11 , reducing the weight of the bottom plate  11 , and then making the product lighter as a whole. The friction resistance between the abrasive strip II  22  and the hollow groove  113  is high, so the user needs to pull the drawer  2  with a little force, which ensures the stability of the drawer  2 . 
     As a specific technical solution of the embodiment, both the top end and the bottom end of the column  13  are provided with inserting plates  133  on both sides of the clamping plates  131 . The ends of the inserting plates  133  far from the column  13  extend into the insertion grooves  14 , and the sides of the clamping plates  131  far from the clamping blocks  132  are provided with reinforcing ribs  134 . The reinforcing ribs  134  ensure the stability of the clamping plates  131  and avoids the fracture after multiple plugging and pulling. The inserting plates  133  increase the stability and area of the connection between the column  13  and the bottom plate  11  and the top, and can also protect the clamping plates  131 . When the product is disassembled, since the inserting plates  133  are located on both sides of the clamping plates  131 , the clamping plates  131  will not be damaged in case of collision. 
     As a specific technical solution of the embodiment, at least one support rib  135  is disposed on the side of the column  13  towards the drawer  2 , and the inserting plates  133 , the clamping plates  131 , the reinforcing ribs  134  and the clamping blocks  132  are integrally formed. A plurality of support ribs  135  are disposed on the side of the column  13  towards the drawer  2 , which ensures the overall structural strength of the column  13 , while saving processing raw materials, which is economical. 
     As a specific technical solution of the embodiment, a connecting enclosure  111  is disposed on the top of the bottom plate  11  , the insertion grooves  14  on the bottom plate  11  are disposed in the connecting enclosure  111 , side plates  121  are disposed at both bottom sides of the top plate  12 , and the insertion grooves  14  on the top plate  12  are disposed in the side plates  121 . The connecting enclosure  111  is used to cover one side of the drawer  2 . One side of the connecting enclosure  111  has a gap, so that the drawer  2  can be drawn freely through the gap. The side plates  121  can cover both sides of the drawer  2 . Since the enclosure limits the drawing direction of the drawer  2 , the top plate  12  only needs to protect both sides of the drawer  2  on the side plates  121 . The insertion grooves  14  are in the side plates  121  and the connecting enclosure  111 . The hidden design makes the appearance beautiful. 
     As a specific technical solution of the embodiment, the positioning enclosure  112  is also provided with at least one positioning annular groove  116  for placing rubber pads. The slide rail  114  comprises a guide rail I  1141  and a guide rail II  1142  fixedly disposed on the bottom plate  11  and respectively located on both sides of the slide rod  21 . One end of the guide rail II  1142  is fixedly connected to one side of the inner wall of the connecting enclosure  111  through a connecting part  115 . The positioning annular groove  116  is used for installing the rubber pads. After the rubber pads are installed in the positioning annular groove  116 , the positioning enclosure  112  does not directly contact the ground. The contact between the rubber pads and the ground makes the anti-skid effect better, and also reduces the wear of the positioning enclosure  112 . The guide rail I  1141  and guide rail II  1142  are used together with the slide rod  21  to ensure the stability of the drawer  2  during storage. At the same time, one end of the guide rail II  1142  is fixedly connected to the connecting enclosure  111  through the connecting part  115 . When the connecting enclosure  111  is impacted by the drawer  2 , the connecting enclosure  111  pulls the guide rail II  1142  through the connecting part  115 , which further ensures the stability of the connecting enclosure  111  and the guide rail II  1142 . 
     As a specific technical solution of the embodiment, the clamping grooves  15  are inclined. Clamping parts  16  are disposed at the bottoms of the clamping grooves  15 . The clamping blocks  132  are clamped with the clamping parts16.The clamping blocks  132  respectively with arc-shaped end match with the inclined clamping grooves  15 , which facilitates the insertion of the clamping blocks  132  and makes the insertion process smoother. The clamping parts  16  can be stably clamped with the clamping blocks  132 , making the connection between the column  13 , the bottom plate  11  and the top more stable. 
     As a specific technical solution of the embodiment, through holes  17  corresponding to the clamping parts  16  are disposed at the bottom of the bottom plate  11  and the top of the top plate  12 . The clamping blocks  132  can be warped by tools through the through holes  17 . When disassembling the bottom plate  11 , the column  13  and the top plate  12 , a screwdriver or any other tool can be used to lift the clamping blocks  132  through the through holes  17  at the bottom of the bottom plate  11  and the top plate  12 , so that the clamping blocks  132  are separated from the clamping parts  16 , and then the clamping plates  131  can be pulled out from the clamping grooves  15 . The operation is simple and fast. 
     As a specific technical solution of the embodiment, at least one abrasive strip I  123  is disposed in the positioning groove  122 . When stacking two slide frames  1 , the abrasive strip I  123  increases the friction between the positioning groove  122  and the positioning enclosure  112 . When stacking two slide frames  1 , the bottom of the positioning enclosure  112  contacts with the abrasive strip I  123  to make the connection more stable 
     When in use, pull the drawer  2  through the handle  24 , the drawer  2  drives the slide table to slide in the slide rail  114 , and the drawer  2  is taken out through the gap at one side of the connecting enclosure  111 . When multiple products are stacked together, lift the other slide frame  1 , and clamp the positioning enclosure  112  at the bottom of the slide frame  1  with the positioning groove  122  at the top of the other slide frame  1 , so that the two slide frames  1  can be combined. When disassembling the slide frame  1 , use a tool to tilt the clamping blocks  132  through the through holes  17  at the bottom of the bottom plate  11  and the top plate  12 , so that the clamping blocks  132  are separated from the clamping parts  16 . In this way, the clamping plates  131  are pulled out from the clamping grooves  15 . After that, the bottom plate  11 , the column  13  and the top plate  12  can be disassembled. The above is the operation method of the product. 
     The invention has the following advantages and benefits in comparison with the conventional storage containers: the storage container is equipped with the slide frame  1  and the drawer  2 , and adopts the drawer type to achieve independent use, or multiple products can be stacked together for use without affecting the independent drawing action. The bottom plate  11 , column  13  and top plate  12 , which form the slide frame  1 , are movably clamped. Therefore, the invention has the advantages of convenient disassembly and assembly, high stability after assembly, low cost and practicality, and broad application prospects 
     While the invention has been described in terms of preferred embodiments, those skilled in the art will recognize that the invention can be practiced with modifications within the spirit and scope of the appended claims.
