[0036] Referring to Figures 1-4As shown, the two side top portions of the U-shaped support frame 3 are combined with limiting anti-loose assemblies 5, which prevent the multiple shaping protection assemblies 4 from slipping and the cell factory breathable cover 1 from accidentally loosening through the limiting anti-loose assemblies 5. Specifically, the limiting anti-loose assemblies 5 each include a matching sleeve 401 and an anti-loose pressing plate 402. The top portion of the vertical part of the U-shaped support frame 3 is vertically sleeved with the matching sleeve 401, and the matching sleeve 401 is pressed from the top to the multiple mounting sleeves 503 on the same side. The end faces of the matching sleeves 401 on the two sides opposite to each other are horizontally extended and fixed with the anti-loose pressing plates 402, and the anti-loose pressing plates 402 are pressed to the top surface of the corresponding side of the cell factory breathable cover 1. The outer end faces of the matching sleeves 401 on the two sides away from each other are transversely provided with mounting holes 403. The mounting holes 403 are through holes and coaxially inserted and additionally provided with locking screws 404 in a threaded matching manner. In this way, firstly, the matching sleeves 401 of the limiting anti-loose assemblies 5 can press the mounting sleeves 503 to prevent the multiple shaping protection assemblies 4 from slipping during use. Meanwhile, the anti-loose pressing plates 402 of the limiting anti-loose assemblies 5 can press the cell factory breathable cover 1 to prevent the cell factory breathable cover 1 from accidentally loosening, thereby achieving the limiting and anti-loose functions of the shaping protection assemblies 4 and the cell factory breathable cover 1 at the same time. Furthermore, the limiting anti-loose assemblies 5 can be quickly combined on the side of the U-shaped support frame 3 by vertically sliding the matching sleeves 401 along the side of the U-shaped support frame 3 and then tightening the locking screws 404. Moreover, the limiting anti-loose assemblies 5 can be easily disassembled from the side of the U-shaped support frame 3 by loosening the locking screws 404 and then vertically sliding the matching sleeves 401 upward.

[0037] Referring to Figures 1-8 As shown, the U-shaped support frame 3, the shaping protection assembly 4, and the limiting anti-loose assembly 5 are respectively optimized as follows. Specifically, the horizontal part of the U-shaped support frame 3 is horizontally and fixedly provided with stable wings 302 of the same thickness at the front and rear positions, so as to increase the contact area of the bottom surface of the U-shaped support frame 3 by means of the wings, thereby enabling the U-shaped support frame 3 to be placed more stably. Meanwhile, the vertical dimensions of the mounting sleeves 503, the protective frames 502, and the cell factory layers 2 are kept consistent, and the mounting sleeves 503 adjacent to each other in the up-down direction are tightly attached to each other, and the protective frames 502 adjacent to each other in the up-down direction are also tightly attached to each other. In this way, the multiple shaping protection assemblies 4 can be indicated to be combined in place by means of the tightly attached mounting sleeves 503 and protective frames 502 adjacent to each other in the up-down direction, and the mounting sleeves 503 in the up-down direction can also be prevented from slipping and shifting.

[0038] Referring to Figures 1-8 Figures 1-8As shown, the elastic lining plates 501 are all low-temperature-resistant rubber lining plates in the rectangular frame style, so that the elastic lining plates 501 have good low-temperature use effect. At the same time, the mounting sleeves 503 and the matching sleeves 401 are all rectangular sleeves, and the horizontal cross-sectional shapes of the vertical parts of the U-shaped support frames 3 are all rectangular, so that the mounting sleeves 503 and the matching sleeves 401 have good positioning and guiding design when sliding vertically along the U-shaped support frames 3. Further, the locking screws 404 are all plastic screws with force applying end heads, and the lengths of the threaded parts of the locking screws 404 are all greater than the hole depths of the mounting holes 403, so that the locking screws 404 are easy to purchase and can be pressed against the corresponding side end faces of the U-shaped support frames 3. Further, the force applying grooves 301 for conveniently holding are arranged on the vertical parts of the U-shaped support frames 3 at positions higher than the top faces of the matching sleeves 401, so that the U-shaped support frames 3, the cell factory layer bodies 2 and the cell factory gas permeable covers 1 can be moved as a whole by holding the force applying grooves 301 with both hands.

[0039] With the above structure, in actual use, the multi-layer cell factory layer body 2 is stacked together and placed on the U-shaped support frame 3 after the cell factory gas permeable cover 1 is installed on the top, and the number of layers of the shaped protection assembly 4 is consistent with the number of cell factory layer bodies 2, which is combined between the two sides of the U-shaped support frame 3. Then, by means of the elastic lining plate 501 inside the shaped protection assembly 4 and the outer periphery of the cell factory layer body 2, the cell factory layer body 2 can be externally shaped and protected by the protection frame 502 and the elastic lining plate 501 of the shaped protection assembly 4. Therefore, when the cell factory layer body 2 is taken out in a low temperature environment, the external protection of the shaped protection assembly 4 can avoid the damage of the cell factory layer body 2 caused by direct contact and movement of personnel. Since the elastic lining plate 501 inside is quickly and tightly matched with the outer periphery of the cell factory layer body 2 by means of the installation sleeve 503 sliding vertically along the side of the U-shaped support frame 3, and then only needs to be lifted to make the installation sleeve 503 slide up along the U-shaped support frame 3, the elastic lining plate 501 inside and the outer periphery of the cell factory layer body 2 can be separated from each other. The combination and disassembly of the shaped protection assembly 4 outside the cell factory layer body 2 is simple and easy to realize. It is convenient to quickly combine the shaped protection assembly 4 outside the cell factory layer body 2 for use, and then separate and store the shaped protection assembly 4 after disassembling it from the outside of the cell factory layer body 2. Since the limiting anti-loose assembly 5 is combined on the top of the two sides of the U-shaped support frame 3, and then the installation sleeve 503 is pressed by the matching sleeve 401 of the limiting anti-loose assembly 5, it can prevent the shaped protection assembly 4 from sliding and moving during use. At the same time, by means of the anti-loose pressing plate 402 of the limiting anti-loose assembly 5 pressing the cell factory gas permeable cover 1, it can prevent the cell factory gas permeable cover 1 from accidentally loosening, and realize the limiting and anti-moving of the shaped protection assembly 4 and the cell factory gas permeable cover 1 at the same time, which is convenient for the stable and reliable use of the shaped protection assembly 4 and the cell factory gas permeable cover 1. Since the limiting anti-loose assembly 5 is quickly combined on the side of the U-shaped support frame 3 by means of the matching sleeve 401 sliding vertically along the side of the U-shaped support frame 3 and then tightening the locking screw 404, and only needs to loosen the locking screw 404 to make the matching sleeve 401 slide vertically and then separate from the top end of the side of the U-shaped support frame 3, the combination and disassembly of the limiting anti-loose assembly 5 on the side of the U-shaped support frame 3 is simple and easy to realize. It is convenient to quickly combine the limiting anti-loose assembly 5 on the side of the U-shaped support frame 3 for use, and then store and disassemble the limiting anti-loose assembly 5 for use, and then disassemble the shaped protection assembly 4 in turn.

[0040] The above merely describes a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
