[0029] Reference Figure 1 , Figure 3 and Figure 4According to the support 100 in the embodiment of the present application, the one end of the adjusting pipe 102 is connected with the base 101, the adjusting pipe 102 comprises a core 401, an intermediate layer 402 and an outermost layer 403 which are sequentially sleeved from inside to outside, the core 401 can produce plastic deformation, can be bent when subjected to external force and maintain the shape after the external force is eliminated, the intermediate layer 402 has elasticity, the bending resistance of the intermediate layer 402 can be adjusted, and the outermost layer 403 has flexibility. The fixing base 103 is connected with the one end of the adjusting pipe 102 away from the base 101, when the adjusting pipe 102 is subjected to external force, the adjusting pipe 102 can be bent to change the position of the fixing base 103 relative to the base 101, and the adjusting pipe 102 maintains the shape unchanged after the external force is eliminated. The adjusting pipe 102 in the prior art usually only has a core 401 capable of producing plastic deformation inside, and a flexible protective layer is wrapped outside, and it is difficult to adjust the internal organization and mechanical properties after the plastic material is processed and formed, and the bending resistance of the adjusting pipe 102 basically depends on the material of the core 401, that is, the bending resistance of the adjusting pipe 102 can be changed only by changing the composition of the core 401, which is not convenient. The support 100 in the embodiment of the present application adds the intermediate layer 402 with elasticity between the core 401 capable of plastic deformation and the outermost layer 403, the bending resistance of the elastic structure is more easily adjusted, and the adjustment can be performed without changing the internal composition, for example, when the intermediate layer 402 is a spring, the number of turns of the spring is increased or decreased, or when the intermediate layer 402 is a threaded pipe, the pitch of the threaded pipe is changed, and the bending resistance can be quickly adjusted, so that the bending resistance of the adjusting pipe 102 of the support 100 can be more easily adjusted, and more diverse product requirements can be met.

[0030] It should be noted that, in some embodiments of the present application, the fixing base 103 of the support 100 can be used to place a mobile phone, and can also be used to place a tablet and other portable electronic products, and the use scene of the support 100 is not limited to the car, and can also be used in the family, outdoor and other scenes to fix the portable electronic products.

[0031] In some embodiments of the utility model, the intermediate layer 402 is a threaded pipe, and the pitch of the threaded pipe can be adjusted. The threaded pipe has good flexibility and elasticity, and the support structure formed by the threads of the threaded pipe makes it not easy to deform after being stressed. By sleeving the threaded pipe on the outer layer of the core 401, the overall bending resistance of the adjusting pipe 102 can be better adjusted. Moreover, the bending resistance of the threaded pipe is related to the pitch size. The pitch refers to the axial distance between the two corresponding points on the pitch line of adjacent threads. When the pitch of the threaded pipe is large, it is more likely to bend and deform under the same external force because a larger pitch means a larger distance between threads, which relatively weakens the constraint on the overall structure of the threaded pipe, so that it can change shape more freely when stressed, showing relatively soft characteristics. A smaller pitch makes the threads closer, and the mutual support between adjacent threads is enhanced, thereby improving the structural stability. This makes the threaded pipe less likely to bend and deform when subjected to external force, showing relatively hard characteristics. Therefore, the bending resistance of the threaded pipe can be changed by adjusting the pitch of the intermediate layer 402 during manufacturing, without changing the material, which is more convenient to adjust.

[0032] It should be noted that in some embodiments of the utility model, the intermediate layer 402 can also be set as a spring. By adjusting the pitch of the spring, the bending resistance of the spring can also be changed. The pitch of the spring refers to the axial distance between the center lines of adjacent two coils of the spring. When the pitch increases, the gap between the adjacent two coils of the spring increases, and the coils of the spring are relatively looser, which is equivalent to reducing the mutual constraint between the coils of the spring. When subjected to external force that bends the spring, the coils are more likely to displace and deform relative to each other, so the overall spring will exhibit a characteristic of being more likely to bend. Conversely, when the pitch decreases, the coils are closer to each other and are less likely to displace and deform relative to each other, thereby enhancing the bending resistance. When the intermediate layer 402 is set as a spring, the two ends of the intermediate layer 402 can be fixedly connected to the core 401, and the bending resistance of the middle part of the intermediate layer 402 that is most likely to deform can be changed by changing the spring pitch of the middle section, thereby exhibiting the overall bending resistance of the adjusting pipe 102. This process can be adjusted during manufacturing, or the intermediate pipe can be adjusted separately after forming, which is more convenient.

[0033] In some embodiments of the utility model, the material of the intermediate layer 402 is low-carbon steel. Low-carbon steel refers to carbon steel with a carbon content of less than 0.25%. Low-carbon steel has good toughness and can produce large deformation without breaking when stressed and deformed. By manufacturing it into a threaded pipe, the adjustment is better, and both flexible adjustment and rigidity requirements can be met.

[0034] In some embodiments of the utility model, the material of core body 401 is aluminum, and / or the material of outermost layer 403 is silica gel. Aluminum has low density and high strength, which can reduce the overall weight of adjusting pipe 102, is suitable for frequent adjustment and carrying, and the good ductility of aluminum also makes it more convenient to process. In some embodiments, alloy elements can also be added to process aluminum alloy to change its mechanical properties, meet more diversified needs, or replace core body 401 with zinc alloy which also has good plastic deformation ability. The material of outermost layer 403 is set to silica gel because silica gel is soft and has excellent elasticity, users can feel good touch when holding adjusting pipe 102, and silica gel itself is not easy to break after bending due to deformation, and silica gel also has certain anti-slip properties, so that users can better exert force when bending adjusting pipe 102. Silica gel is also relatively slip-resistant and wear-resistant, and can maintain a perfect appearance after long-term use, improving the aesthetics of support 100. In some embodiments of the utility model, outermost layer 403 can also use materials such as TPE (thermoplastic elastomer) and injection-molded silica gel.

Adjusting pipe 102 is a multi-layer nested strip structure. If adjusting pipe 102 is directly inserted into the hole of base 101, it is easy to cause loosening or falling off of the connection between adjusting pipe 102 and base 101 during frequent bending. Therefore, adapter 201 is provided to better connect adjusting pipe 102 and base 101. First part 202 is fixedly connected with adjusting pipe 102, and then second part 203 is connected with base 101. Different styles of adapter 201 can be designed according to the shape of base 101 for easy installation, without the need to process adjusting pipe 102, so as not to affect the mechanical properties of intermediate layer 402 and core body 401 in adjusting pipe 102. Specifically, reference Figure 4 In some embodiments of the utility model, first part 202 is sleeved on the outer circumferential surface of intermediate layer 402 and connected with outermost layer 403.
