[0023] In order to make the above objectives, features and advantages of the present application more apparent, specific embodiments of the present application are described in detail below with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways other than those described herein without departing from the spirit of the present application, and it is understood that similar modifications can be made by those skilled in the art in the light of the foregoing description. Therefore, it is not intended to limit the present application to the following specific embodiments disclosed below.

[0024] As described in the background, the random placement of the pressing net in the related art is prone to damage the pressing net. The inventor has found that the damage to the pressing net usually includes the following: the pressing net pressing needle is deformed or worn due to collision, causing the pressing net pressing needle to jam, and the use of the battery piece will cause the battery piece to crack; for example, the pressing net spring is prone to fatigue, causing the spring to fail; for example, the pressing net frame is usually made of aluminum, and the random placement is prone to cause the pressing net frame to fall and be deformed, thereby causing the pressing net frame to be scrapped and causing resource waste. If the damaged pressing net is repaired manually, the time spent on manual repair and the reliability of the inspection are difficult to guarantee, causing resource waste.

[0025] Based on the above reasons, the present application provides a stringer pressing net placing box which can place the pressing net more regularly, effectively reduce the probability of damage to the pressing net, and thereby improve the product quality.

[0026] Referring to Figure 1 and Figure 2 , Figure 1 Figure 1 shows a structure diagram of a stringer pressing net placing box according to an embodiment of the present application.

Each plug-in part 102 can be inserted with one pressing net 20 in a vertical manner, and the pressing net 20 inserted in the inside of the plug-in part 102 is fixed vertically in the inside of the receiving chamber 101.

[0027] The placing box body 10 described above can be used to insert a plurality of pressing nets 20 into the plurality of insertion parts 102, so that the plurality of pressing nets 20 are fixed in the storage chamber 101 of the placing box body 10. It can be seen that the arrangement of the pressing nets 20 is regular and neat, and since each pressing net 20 is placed vertically, the damage probability of the pressing net 20 can be effectively reduced, thereby improving the product quality.

[0028] For ease of understanding, the placing box 10 of the stringer for the pressing net 20 is taken as an example, the pressing net needle and the pressing net spring are not in contact with the outside world and are in a natural extension state, thereby avoiding damage to the pressing net needle, failure of the pressing net spring and deformation and damage of the pressing net frame caused by random placement.

[0029] In addition, each pressing net 20 is placed separately and vertically, and does not affect each other in terms of wear and extrusion. The pressing net 20 can be completely immersed in the storage chamber 101, and will not be deformed and worn by external force during transportation. The placing box body 10 can adapt to the standardized taking and placing operation of the plurality of pressing nets 20, so as to facilitate the realization of standardized transportation, thereby facilitating the realization of unified management, reducing the abnormal frequency of the pressing net 20, reducing the maintenance manpower of the pressing net 20, and reducing the damage of spare parts.

[0030] In some embodiments, the number of insertion parts 102 inside the storage chamber 101 includes but is not limited to 2, 10, 20, 22, 25, 30, 50 or more, and the specific number can be flexibly adjusted and set according to actual needs, which is not limited here.
