While the following two effects can be achieved when the drawer is opened and closed:

(1) the sliding plate 31 is directly pulled to move towards the right side in the figure, and at the moment, the rebound sliding plate 61 is limited by the limiting column to be fixed with the plate body; the slide plate 31 is continuously pulled to move towards the right side in the figure, at the same time, external force causes the slide plate 31 and the base plate 41 to move, at the same time, the spring is stretched to exert resistance, then, the guide groove 43 in the base plate drives the poke rod 36 and the swing part connected with the poke rod 36 and the slide plate 31 to move on the guide plate 13, at the same time, the limit column 36 moves towards the clamping part 15 in the chute 14, when the limit column 36 enters the bending part below the clamping part 15, external force is continuously exerted on the base plate 41 to cause the poke rod 36 to move upwards through the guide groove, the swing part drives the limit column 35 below to enter the clamping part 15 from the chute, then, external force is continuously exerted on the base plate to cause the poke rod 36 to cross the highest point 44 of the bending part above the guide groove, the poke rod 36 drives the swing part and the limit column below to enter the clamping part 16, and thus, the slide plate 31 realizes the re-limit of the slide plate through the clamp of the limit column 36 and the clamping part 15, continued movement of the base plate then causes the base plate 41 to disengage from the tap lever 35, which causes the drawer to be opened.

When the drawer needs to be closed, the sliding plate 31 moves towards the left side in the figure, the substrate 41 moves towards the sliding plate 31 from the front of the guide plate, when the drawer needs to be closed, the substrate 41 drives the inlet 45 to be clamped on the poking rod 36 (shown in figures 6 and 7), the poking rod 36 is guided through the guide groove 43 along with the continuous movement of the substrate 42 (the substrate 41 is not movable in the vertical direction but only can move leftwards and rightwards during the movement) and causes the limiting column 35 fixedly connected with the substrate 41 to slide out from the clamping part 15, then the poking rod enters the guide groove (shown in figures 8 and 9), then the spring exerts pulling force on the sliding plate 31 and causes the sliding plate 31 to slide on the guide plate 13 and move towards the plate body 10, at the moment, the poking rod is positioned in the guide groove and drives the substrate 41 to move together, when the sliding plate moves, the self-locking resistance oil cylinder exerts resistance opposite to the spring, and the slow movement of the sliding plate is realized, the smooth sliding is realized, the limitation on the sliding plate can be removed, and then the drawer is closed.

(1) When the drawer needs to be opened, when the rebound driving piece is pressed for 2-3mm, the sliding plate 62 moves towards the left side in the figure and enables the lower end of the V-shaped opening 58 to abut against the limiting column 53 and move the limiting column out of the limiting groove 52 through the inclined surface 57 of the V-shaped opening 58 (see fig. 13 and 15), after the limiting column moves out of the limiting groove 52, the sliding plate 62 can be loosened, at the moment, the rebound sliding plate is outwards popped out through the action of the rebound spring 62, and at the moment, the ejector rod at the front end of the rebound sliding plate abuts against the sliding plate 31 and enables the rebound sliding plate to be popped out and move towards the right side in the figure.

At this time, the spring shape remains unchanged, the guiding groove 43 in the substrate drives the poke rod 36 and the swing part and the sliding plate 31 connected with the poke rod 36 to move on the guiding plate 13, at this time, the limit post 36 moves towards the direction of the clamping part 15 in the sliding groove 14, when the limit post 36 enters the bending part below the clamping part 15, the poke rod 36 moves upwards through the guiding groove, and the swing part drives the limit post 35 below to enter the clamping part 15 from the sliding groove, then the rebound spring 62 continuously applies forward force to the substrate (the force is provided by the rebound spring 62), so that after the poke rod 36 passes through the highest point 44 of the upper bending part, the poke rod 36 drives the swing part and the limit post below to enter the clamping part 16, thus, the sliding plate is clamped with the clamping part 15 through the limit post 36 to realize the re-limiting of the sliding plate, then the substrate continues to move to separate the substrate 41 from the poke rod 35, the drawer can be driven to be opened through the operation, and the operation of opening the drawer can be realized only by pressing the rebounding driving piece when the drawer is opened.

When the drawer needs to be closed, the sliding plate 62 is pushed and the sliding plate 62 is driven to move towards the left side in the figure, when the drawer moves, the side wall 55 in front of the convex body on the driving part 54 firstly contacts with the limiting column and abuts against the limiting column to drive the limiting column to move in the guide groove, at the moment, the rebound spring is stretched to apply resistance, external force is continuously applied, the limiting column is jacked at the joint of the limiting groove and the guide groove through the side wall 55 in front of the convex body, and due to the fact that the side face in contact with the side wall 55 in front of the convex body is obliquely arranged, the external force is continuously applied at the moment, and the side wall 55 in front of the convex body jacks the limiting column into the limiting groove to limit the rebound sliding plate (shown in fig. 18).

When the limit post is positioned at the position of the connection part of the limit groove and the guide groove, the poke rod 36 causes the limit post 35 fixedly connected with the limit post to slide out of the clamping part 15, then the poke rod enters the guide groove (shown in figures 8 and 9), then the hand can be released after the limit post is jacked into the limit groove, then the spring exerts pulling force on the sliding plate 31 and causes the sliding plate 31 to slide on the guide plate 13 and move towards the plate body 10, at the moment, the poke rod is positioned in the guide groove and drives the base plate 41 to move together, when the sliding plate moves, the self-locking damping oil cylinder exerts resistance opposite to the spring, and slow movement of the sliding plate is realized, smooth sliding is realized, then the drawer is closed, and because the spring exerts pulling force on the sliding plate at the moment, the pulling force can cause the drawer to be closed tightly.

The embodiment of the present invention discloses a preferred embodiment, but not limited thereto, and those skilled in the art can easily understand the spirit of the present invention according to the above embodiment, and make different extensions and changes, but do not depart from the spirit of the present invention, all of which are within the protection scope of the present invention.
