Therefore, when the rotating shaft 122 rotates, the locking protrusion 1223 can rotate relative to the supporting portion 124 and the base 11 along with the rotating shaft 122, and under the limiting effect of the supporting portion 124 and the drawer space 11a facing the side wall of the drawer opening 11b to the locking protrusion 1223, the rotating shaft 122 cannot slide close to or far away from the drawer opening 11b, and then cooperates with the limiting groove to limit the rotating shaft 122, so that the rotating shaft 122 cannot move in four directions of horizontal front, rear, left and right directions, and the stability and reliability of the rotating shaft 122 can be improved when the locking piece 12 is used.

When the display main body 2 is installed in the drawer space 11a in this embodiment, the key 121 is pressed to move the key 121 downward, the rack 1211 on the key 121 applies downward force to the rotating shaft 122 through the gear 1222, the rotating shaft 122 is balanced in force in the vertical direction under the support of the supporting portion 124, and the key 121 drives the rotating shaft 122 to rotate through the cooperation of the rack 1211 and the gear 1222, so that the first connecting portion 1221 on the rotating shaft 122 rotates to a position capable of being separated from the second connecting portion 211 on the display main body 2, and the display main body 2 is pushed into the drawer space 11a. When the main body 2 to be displayed is abutted against the side wall of the drawer space 11a facing the drawer opening 11b, the rotating shaft 122 is positioned between the main body 2 and the supporting part 124, the key 121 is loosened, the key 121 moves upwards under the action of the elastic part 123, the rack 1211 on the key 121 applies upward acting force to the rotating shaft 122 through the gear 1222, the rotating shaft 122 is not separated from the limiting groove on the supporting part 124 under the stop limiting action of the main body 2 even if the rotating shaft 122 is stressed in the vertical direction, the key 121 drives the rotating shaft 122 to rotate through the cooperation of the rack 1211 and the gear 1222, so that the first connecting part 1221 on the rotating shaft 122 rotates to a position in connection with the second connecting part 211 on the main body 2, and the installation and fixation of the main body 2 to be displayed in the drawer space 11a are realized by means of the connection of the first connecting part 1221 and the second connecting part 211.

Therefore, in this embodiment, the rotation shaft 122 is limited in the horizontal direction by the limiting groove on the supporting portion 124, and the rotation shaft 122 is limited in the vertical direction by the supporting portion 124 and the display main body 2, so that the rotation of the rotation shaft 122 is stable and reliable in the use process of the locking member 12, the cooperation of the rack 1211 and the gear 1222 is also stable and reliable, and the reliability and stability of the disassembly and assembly of the display main body 2 can be improved.

In an embodiment of the present invention, as shown in fig. 3 to 6, a guide groove 11e extending toward the drawer opening 11b is formed in the drawer space 11a, and the display main body 2 is slidably limited in the guide groove 11e.

In this embodiment, the guide groove 11e is used for realizing the moving guide of the display main body 2 in the drawer space 11a, and the guide groove 11e also plays a role in supporting and limiting the display main body 2, so that the display main body 2 can be prevented from shaking in the vertical direction and the horizontal direction, and the display main body 2 is prevented from being damaged during disassembly and assembly and use. In addition, the guiding groove 11e also plays a role in positioning the display main body 2, the guiding groove 11e restrains the moving direction and the moving range of the display main body 2 during installation, when the display main body 2 moves along the guiding groove 11e to be in contact with the side wall of the guiding groove 11e facing the drawer opening 11b, the second connecting part 211 on the display main body 2 can be accurately aligned with the first connecting part 1221 on the rotating shaft 122, and the first connecting piece can be accurately connected with the second connecting piece during rotation of the rotating shaft 122.

The guide groove 11e in this embodiment may include two groove sections respectively formed on opposite side walls of the drawer space 11a, along which two ends of the display main body 2 can slide. The guide slot 11e can also be an interlayer space in the drawer space 11a, at this time, a partition plate is arranged in the drawer space 11a, the partition plate divides the drawer space 11a into an upper interlayer space and a lower interlayer space, the upper interlayer space is the guide slot 11e, the display main body 2 is slidingly limited in the upper interlayer space, the rotating shaft 122 is accommodated in the lower interlayer space, the rotating shaft 122 is not contacted with the display main body 2 under the isolation of the partition plate, and the risk of mutual damage generated between the rotating shaft 122 and the display main body 2 during the rotation can be reduced. The partition board is also provided with a first avoidance hole and a second avoidance hole which can be used for the first connecting part 1221 to pass through, the first avoidance hole is arranged corresponding to the first connecting part 1221, and the upper interlayer space is communicated with the lower interlayer space through the avoidance hole; the key 121 passes through the second avoidance hole, and the second avoidance hole is used for avoiding the key 121 and the limiting block 1212 on the key 121 so as to avoid interference with the movement of the key 121. When the rotating shaft 122 rotates, the first connecting portion 1221 passes through the avoidance hole and is connected to the second connecting portion 211 on the display main body 2 located in the upper interlayer space.
