The transmission component 7 is used for driving the grabbing component 8 to act so as to take and place chopsticks into the chopstick cage 4; the method comprises the following steps:

the handle 71 is accommodated in the groove 11, two ends of the handle are respectively connected with the two sliding blocks 73 through the rotating shaft 72, the two sliding blocks 73 are respectively arranged on the two positioning rods 74 in a sliding manner, the two second elastic pieces 75 are respectively sleeved on the two positioning rods 74, the second elastic pieces in the embodiment are springs, and two ends of the second elastic pieces respectively abut against the bottom plate 22 and the sliding blocks 73, so that the sliding blocks 73 have a tendency of moving upwards; the two rotating shafts 72 are respectively connected with two pull rods 76 in a driving way.

The grabbing component 8 is used for grabbing chopsticks in the chopstick cage 4 and comprises a grabbing hand 81, the grabbing hand 81 is hinged to a connecting rod 82 through a connecting shaft 83, the connecting rod 82 is connected with the upper end parts of the two supporting rods 42 and connected with the two pull rods 76, and the grabbing hand can move up and down under the action of the pull rods 76.

A torsion spring 84 is arranged between the connecting shaft 83 and the hand grip 81, so that the hand grip 81 has a tendency of maintaining an initial position, and the hand grip 81 is convenient to reset after rotating.

The hand grip 81 has an arc surface or an inclined surface and a hook portion connected to the arc surface or the inclined surface, and the hook portion is located above the inclined surface or the arc surface. Under the condition that the handle is not stressed, the inclined surface or the cambered surface of the hand grip 81 is abutted against the side surfaces and the upper surfaces of the chopsticks in the chopstick cage 4 and can slide along the surfaces of the chopsticks. The hand grip 81 in this embodiment is substantially a right triangle, and the upper surface thereof may be a concave arc surface.

The working principle of taking and placing chopsticks by the drawer door body structure is described as follows by taking a chopstick taking state as an initial state:

in an initial state, the inclined plane of the gripper is abutted against the uppermost chopstick in the chopstick cage 4, the hand presses the handle downwards and then is immediately loosened, the slider is sequentially driven to move downwards along the positioning rod and the pull rod moves downwards along the support rod in the process of pressing the handle downwards, at the moment, the limit rod is abutted against the limit surface of the second limit rack, so that the second limit rack cannot move downwards, namely, the supporting plate cannot move downwards, the gripper is extruded by the chopsticks in the process of moving downwards along with the connecting rod, the gripper rotates clockwise, when the gripper rotates to the position below the uppermost chopstick, the gripper is separated from the moment of extruding the chopsticks and rotates anticlockwise under the action of the torsion spring to scoop the uppermost chopstick, and meanwhile, the two sliders move upwards under the action of the second elastic piece to drive the parts to move upwards to send the chopsticks out, so that the uppermost chopstick is exposed out of the chopstick holes, and people can take the chopsticks conveniently.

After the uppermost chopstick is taken out, the supporting plate moves upwards under the action of the first elastic piece and drives the two limiting racks to move upwards at the same time; in the process of moving the second limiting rack upwards, because the limiting rod is contacted with the inclined plane which is inclined downwards, the inclined plane of the teeth extrudes the connecting seat along with the upward movement of the limiting rack, the connecting seat extrudes the limiting elastic part, and the connecting seat drives the limiting rod to move backwards; when the limiting rod is separated from the tooth and enters the next tooth, the force applied to the connecting seat is removed, the connecting seat is reset under the elastic action of the limiting elastic piece, and the limiting rod is abutted to the bottom surface of the next tooth.

When the shifting rod passes through the shifting rod, the shifting rod can instantly enter the reversing notch, and when the shifting rod reaches the middle position of the reversing notch, the limiting elastic piece is in a free state; because the force applied to the handle is cancelled at the moment, the supporting plate drives the reversing rod to move upwards continuously under the action of the second elastic piece, and because the reversing notch is inclined, the shifting rod is extruded out in the upward movement process of the reversing rod, and the limiting elastic piece is stretched; when the middle position of the two limiting notches is reached, the limiting rod just props against the bottom surface of the lower tooth.

Each time the handle is pressed, one chopstick can be taken out, and the steps are repeated in a circulating way until the number of the taken chopsticks meets the requirement.

When the chopsticks are needed to be placed in the chopstick cage 4, the limiting rod needs to be reversed firstly, and the position of the first rack is changed. The specific operation is as follows:

the handle is pressed downwards and is not loosened, the handle moves downwards to drive other parts to act as the same as the chopsticks taking, firstly, after the handle grabs and takes out one chopstick, in the process of moving upwards of the reversing rod, when the shifting rod enters the next reversing notch, the force applied to the handle is not cancelled, under the combined action of extrusion force generated by the continuous downward pressing and the upward movement of the reversing rod, the limiting elastic part is extruded from a free state until the shifting rod is separated from the other side of the limiting notch, and at the moment, the limiting rod is abutted against the top surface of the first limiting rack; the operator can judge that the reversing is finished by hand feeling or sound, and then the force applied to the handle is released to finish the reversing operation.

The chopsticks are placed into the chopstick cage from the chopstick holes one by one, the chopsticks are pressed downwards each time, the elasticity of the torsion spring and the gripper rotate, and then the chopsticks can be placed into the chopstick cage one by one. After each chopstick is placed, the force applied to the hand grip is released, and the hand grip automatically resets under the action of the torsion spring.

In the process of putting chopsticks, the force for pressing down the chopsticks is transferred to the supporting plate, the second limiting rack is in a free state at the moment, the first limiting rack limits the upward movement under the action of the limiting rod, and the supporting plate can only move downward at the moment.

The above actions are repeated, and the chopsticks can be completely put into the chopstick cage 4.
