[0021] The fixing mechanism 6 includes a sleeve 61 and a rotating shaft 62. The sleeve 61 is fixedly installed on the upper end of the frame 2, and the sleeve 61 has a symmetrical structure. A pull plate 63 is slidably inserted in the inner cavity of the sleeve 61, and the opposite sides of adjacent pull plates 63 are fixedly installed with fixing rods 64. Two recessed holes 41 are provided on the slide plate 4, and the fixing rod 64 can slide through the frame 2 and be slidably inserted in the recessed holes 41. The opposite ends of adjacent sleeves 61 are penetrated with through holes 610, and the fixing rod 64 is slidably inserted in the through holes 610. The setting and use of the through holes 610 provide a guarantee for the normal sliding of the fixing rod 64. The opposite sides of adjacent pull plates 63 are fixedly installed with springs 65, and the ends of the springs 65 are in contact with the inner wall of the sleeve 61. The rotating shaft 62 is fixedly connected and rotatably inserted at the upper end of the first side plate 21 near the sleeve 61, and a roller 66 is fixedly sleeved on the rotating shaft 62, and a hand wheel 68 is fixedly sleeved on the end of the rotating shaft 62, and an array of grooves 69 are provided on the outer wall of the hand wheel 68. The coordinated use of the hand wheel 68 and the groove 69 provides convenience for the convenient rotation of the rotating shaft 62. Two pull ropes 67 are fixedly connected to the roller 66, and one end of the pull rope 67 away from the roller 66 movably passes through the sleeve 61 and is fixedly connected to the pull plate 63. The opposite ends of the adjacent sleeves 61 are penetrated by through holes 611, and the pull rope 67 is movably inserted in the through holes 611. The setting and use of the through holes 611 provide a guarantee for the normal pulling of the pull rope 67.

[0022] By adopting the above technical solution, when in use, the two hand wheels 68 are rotated synchronously, thereby driving the corresponding rotating shaft 62 to rotate, and then driving the corresponding winding roller 66 to rotate, and further the corresponding two pull ropes 67 can be rolled up, thereby driving the adjacent pull plates 63 to move toward each other, and then driving the adjacent fixed rods 64 to move toward each other and squeeze the corresponding springs 65. When the end of the fixed rod 64 is completely separated from the corresponding recessed hole 41, stop rotating the hand wheel 68 and move the top frame 5 upward, thereby driving the four slides 4 to move gradually upward, and release the two hand wheels 68 when the top frame 5 moves to the highest point. At this time, the spring 65 will drive the corresponding pull plate 63 to reset, thereby driving the corresponding fixed rod 64 to reset, and then the fixed rod 64 can be inserted into another corresponding recessed hole 41, and further the packaging module can be unfolded and fixed.

[0023] The limiting mechanism 8 includes a swivel 81, and inner grooves 52 are provided inside the four corners of the top frame 5, and the swivel 81 is rotatably clamped in the inner groove 52, a swivel rod 82 is fixedly inserted in the middle of the swivel 81, and a torsion spring 83 is movably sleeved on the swivel rod 82, and the two ends of the torsion spring 83 are respectively fixedly connected to the swivel 81 and the top of the inner groove 52, the upper end of the swivel rod 82 rotates through the top frame 5 and a limiting plate 84 is fixedly sleeved at its end, a plug hole 86 is penetrated through the limiting plate 84, and the top end of the swivel rod 82 is fixedly inserted in the plug hole 86, and the limiting plate 84 can slide and fit with the top cover 7, and a push block 85 is integrally formed on the limiting plate 84, and the outer wall of the push block 85 is covered with a layer of anti-slip texture, which can increase friction and facilitate operation.

[0024] By adopting the above technical solution, when in use, the four push blocks 85 are synchronously pushed to rotate, thereby driving the corresponding limit plate 84 to rotate, and then driving the corresponding rotating rod 82 to rotate, and further driving the corresponding rotating ring 81 to rotate, so as to twist the corresponding torsion spring 83, and when the limit plate 84 is completely separated from the top cover 7, the pushing of the push block 85 is stopped and the top cover 7 is removed.

[0025] Working principle: When in use, the two hand wheels 68 are rotated synchronously, so as to drive the corresponding rotating shaft 62 to rotate, and then drive the corresponding winding roller 66 to rotate, and further the corresponding two pull ropes 67 can be rolled up, so as to drive the adjacent pull plates 63 to move toward each other, and then drive the adjacent fixing rods 64 to move toward each other and squeeze the corresponding springs 65. When the ends of the fixing rods 64 are completely separated from the corresponding recessed holes 41, the hand wheels 68 are stopped from being rotated and the top frame 5 is moved upward, so as to drive the four slides 4 to move upward step by step, and when the top frame 5 moves to the highest point, the two hand wheels 68 are released, and at this time the spring 65 will drive the corresponding pull plate 63 to reset, so as to drive the corresponding fixing rod 64 to reset, and then the fixing rod 64 can be inserted into another corresponding recessed hole 41, and further the packaging module can be unfolded and fixed.

[0026] Then, the four push blocks 85 are pushed to rotate synchronously, thereby driving the corresponding limit plate 84 to rotate, and then driving the corresponding rotating rod 82 to rotate, and further driving the corresponding rotating ring 81 to rotate, so as to twist the corresponding torsion spring 83, and when the limit plate 84 is completely separated from the top cover 7, the pushing of the push block 85 is stopped and the top cover 7 is removed, and then the battery cells are connected and fixed to the inner side of the frame 2 in sequence and the top cover 7 is reset and fixed.
