[0019] The present invention will now be described in further detail with reference to specific examples.

[0020] As shown in Figures 1 to 9, the chopstick case includes an outer housing 1, an inner housing 2, and a sheet 3. A pressing member 4 and a fixing member 5 are provided between the outer housing 1 and the inner housing 2. A spring 6 and a position limiting portion 7 are provided at the tip of the inner housing 2. The spring 6 abuts between the pressing member 4 and the inner housing 2, and the position limiting portion 7 and the fixing member 5 are locked by limiting the position. When the pressing member 4 is pressed down, the bottom of the pressing member presses the position limiting portion, and the position limiting lock between the position limiting portion and the fixing member is released, and the spring is reset, causing the inner housing and the sheet to pop out. In this technical proposal, the outer housing 1 and the inner housing 2 are cylindrical, and the outer housing 1 and the inner housing 2 are connected to each other by the pressing member 4, the fixing member 5, and the position limiting portion 7 at the tip of the inner housing 2 so that the inner housing 22 does not fall off from the outer housing 1. 7, the position limiting part 7 includes a position limiting elastic sheet 71, a spring positioning post 72, a guide locking block 73, and a position limiting locking block 74. In the closed state, the bottom end of the position limiting elastic sheet 71 is blocked by the abutting part 50 and will not fall off the fixed member 5. When the user needs to pop out the sheet 3 to place chopsticks, the user presses the pressing member 4 with his finger, and in the process of the pressing member 4 moving downward, the side of the position limiting elastic sheet 7 presses the position limiting elastic sheet 71, and in the process of the movement, the guide locking block 73 makes the pressing smoother. Referring to FIG. 5, the position limiting elastic sheet 71 is pushed out and deviates from the abutting part 50. 1, a spring 6 is provided between the position limiting portion 7 and the pressing member 4, after pressing, the spring 6 resets and the inner housing 2 pops out, followed by the sheet 3, and when closing, the sheet 3 is pushed up in the same manner, and then the position limiting elastic sheet 71 and the abutment portion 50 are pressed, and the bottom end of the position limiting elastic sheet 71 rebounds after passing the abutment portion 50, and then locks with the abutment portion 50 again, thereby achieving closing. The structure of the box body of this technical solution is simple, easy and quick to use, only requires pressing, and is firm and stable when closing, and not prone to coming apart.

[0021] Furthermore, the sheet 3 is provided with at least one pair of chopstick holes 31, and the bottom outer periphery of the sheet 3 is provided with position limiting steps 33, which abut the bottom of the outer housing 1. In the present invention, the chopstick holes 31 fix the chopsticks, making them easy to insert, quick to handle when stored, easy to butt together, and difficult to shake, the outer wall of the sheet 3 is provided with protruding points 32, and the inner wall of the inner housing 2 is provided with grooves 21 corresponding to the positions of the protruding points 32, and the position limiting steps 33 prevent the sheet 3 from entering too far into the box body, and make it easy to align the protruding points 32 with the corresponding grooves 21 and close them.

[0022] Furthermore, a blocking block 51 is provided inside the fixed member 5, a gap 52 is provided between the blocking block 51 and the side wall of the fixed member 5 at a distance, the side wall of the pressing member 4 is accommodated in the gap 52, a fastener 511 is provided on the side wall of the blocking block 51, and a fastening hole 41 corresponding to the fastener 511 is provided on the side wall of the pressing member 4. In the present invention, the pressing member 4 is provided in the gap 52 of the fixed member 5, is stabilized by the upward and downward rebound of the gap 52, and is firmly fixed via the corresponding fastener 511 and fastening hole 4141.

[0023] The above embodiments are merely preferred embodiments of the present invention, and do not limit the protection scope of the present invention, so that equivalent changes according to the structure, shape and principle of the present invention should be included within the protection scope of the present invention.
