The adjusting chamber 20 is arranged at the middle position of the inner walls on both sides of the housing 1. A rotating rod 14 is arranged inside the adjusting chamber 20. A rotating disk 13 is installed at the lower end of the rotating rod 14. The outer wall of the rotating rod 14 and the inner wall of the adjusting chamber 20 are both provided with a limiting snap ring 22. When the rotating rod 14 and the limiting snap ring 22 on the inner wall of the adjusting chamber 20 are engaged with each other, the rotating rod 14 remains fixed in the adjusting chamber 20. When the rotating rod 14 and the limiting snap ring 22 on the inner wall of the adjusting chamber 20 are separated by rotation, the rotating rod 14 is slidably connected with the adjusting chamber 20. A spring 21 is installed at the upper end of the rotating rod 14, and the other end of the spring 21 is fixed to the upper end of the adjusting chamber 20.

The connecting frame 3 is respectively arranged on both sides of the bottom of the base 2. A lifting rod 15 is arranged at the front end inside the connecting frame 3, and one end of the lifting rod 15 extends to the outside of the connecting frame 3. An insertion rod 17 is installed at the other end of the lifting rod 15. The insertion rod 17 is vertically slidably limited with the base 2, and the lower end of the insertion rod 17 extends to the bottom of the connecting frame 3.

When in use, the limit plates 11 placed perpendicular to each other are moved in the first slide groove 5 and the second slide groove 9 through the pulley 19 to achieve the purpose of adjusting the internal space of the shell 1, and the turntable 13 is rotated to separate the limit snap ring 22 on the rotating rod 14 from the limit snap ring 22 on the adjusting cavity 20, so that the base 2 moves downward. After the adjustment is completed, the turntable 13 is rotated in the opposite direction again to make the limit snap ring 22 on the rotating rod 14 contact and fix with the limit snap ring 22 on the adjusting cavity 20. After the adjustment is completed, the connecting frame 3 is aligned and pushed into the connecting groove 4 on the previous shell 1, so that the insertion rod 17 falls into the slot 18.

Please refer to Figure 2. Pulleys 19 are installed inside the first slide groove 5 and the second slide groove 9. The bare rod part of the screw rod 7 passes through the pulley 19, and the screw rod 7 is connected to the pulley 19 through a bearing. Nuts 8 are provided at one end of the screw rod 7 located outside the base 2 on both sides of the upper limit plate 11 of the longitudinal limit mechanism 6, and the nut 8 is connected to the screw rod 7 through a thread. Nuts 8 are provided at one end of the screw rod 7 located outside the shell 1 on both sides of the upper limit plate 11 of the transverse limit mechanism 10, and the nut 8 is connected to the screw rod 7 through a thread. The function of moving the limit plate 11 and fixing the limit plate 11 by the nut 8 is realized, and the space inside the blister tray can be flexibly adjusted.

Please refer to FIG. 4 , the rotating rod 14 passes through and extends to the bottom of the base 2 , and a turntable 13 is fixedly provided at the bottom of the rotating rod 14 , and the function of separating the base 2 is realized by the turntable 13 , which is convenient for personnel to operate.

Please refer to Figure 1. Both sides of the upper end surface of the shell 1 are provided with connecting grooves 4, and the connecting frame 3 and the connecting groove 4 are slidably matched. A slot 18 is provided on one side of the bottom of the connecting groove 4, which can limit and fix the blister trays to each other, thereby improving the stability of stacking.

Please refer to Figure 5. The staggered positions of the screws 7 in the longitudinal limiting mechanism 6 and the transverse limiting mechanism 10 are both provided with offset holes 23, and the offset holes 23 do not penetrate the limiting plates 11, so that the two limiting plates 11 placed perpendicular to each other will not get stuck during the movement.

Please refer to Figure 3. Turntable placement grooves 12 are set on the left and right sides of the middle position of the front and rear of the upper end face of the shell 1, and the turntable placement grooves 12 and the turntable 13 slide together, so that the two blister trays can be completely fitted together, and the opening of the lower blister tray is covered by the upper blister tray to prevent objects from falling out of the blister tray.

Working principle: When in use, the personnel first adjust the longitudinal limit mechanism 6 and the transverse limit mechanism 10 according to the size of the object to be placed, and respectively make the pulley 19 installed under the screw 7 slide in the first slide groove 5 and the second slide groove 9, driving the limit plate 11 fixed on the screw 7 to move. At this time, the limit plate 11 on the longitudinal limit mechanism 6 can be longitudinally displaced, and the limit plate 11 on the transverse limit mechanism 10 can be transversely displaced. When reaching the appropriate position, the nut 8 is rotated, and the rotational motion is converted into linear motion under the friction between the nut 8 and the external thread of the screw 7, so that the two nuts 8 are respectively approached in the direction of the shell 1 and the bottom bracket 2 until the shell 1 and the bottom bracket 2 are fixed, so that the screw 7 is respectively fixed in the first slide groove 5 and the second slide groove 9, thereby completing the adjustment of the size of the internal space of the shell 1. Subsequently, the personnel can adjust the bottom bracket 2 according to the height of the object. Under normal circumstances, due to the engagement of the rotating rod 14 and the limit clamping ring 22 on the adjusting cavity 20, the bottom bracket 2 is formed at this position. When adjusting, the turntable 13 is rotated to drive the rotating rod 14 to rotate in the adjusting cavity 20. After the turntable 13 is rotated 90 degrees clockwise, the rotating rod 14 and the limiting snap ring 22 outside the rotating rod 14 are separated from the limiting snap ring 22 on the adjusting cavity 20. At this time, the limiting snap ring 22 outside the rotating rod 14 is in the gap between the upper limit snap ring 22 in the adjusting cavity 20. By pulling the bottom bracket 2 downward, when the object reaches the appropriate position, the turntable 13 is rotated 90 degrees counterclockwise again. The upper limit snap ring 22 of the rotating rod 14 is engaged with the upper limit snap ring 22 of the adjustment chamber 20 again to achieve the purpose of adjusting the distance between the base 2 and the shell 1. When the items are placed, the lifting rod 15 is pulled to retract the fixed insertion rod 17 upward into the base 2, and then the connecting frame 3 is aligned and pushed into the connecting groove 4 set on the other shell 1. After it is fully pushed in, the insertion rod 17 automatically falls into the slot 18, so that the base 2 and the other shell 1 are limited and fixed to each other, and the stacking of different blister trays is completed.

It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
