[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-6 , the present invention provides a technical solution: an armrest bone with a hollow structure, as Figure 1 and Figure 2 shown, including a connecting pipe structure 1. The connecting pipe structure 1 includes a connecting cross pipe 101 with weight-reducing holes 102 penetrating through the surface, and an adjusting structure 2 is installed between the connecting cross pipes 101. Among them, there is 1 group of connecting cross pipes 101, and the connecting cross pipes 101 are installed in the above-mentioned scheme. When the connecting cross pipes 101 are installed in the above-mentioned scheme, it effectively plays a fixed installation effect on the hollow adjusting pipe 204.

[0031] As Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, an adjusting structure 2 is fixed between the connecting pipe structures 1. The adjusting structure 2 includes an installation cylinder 201 with a hollow structure inside, and a limiting ring groove 202 is opened inside the installation cylinder 201. There is 1 group of installation cylinders 201, and 3 groups of limiting ring grooves 202 are hierarchically opened inside a single installation cylinder 201. When there is 1 group of the above-mentioned components, it not only reflects the practicability of the installation of the above-mentioned components, but also reflects the sliding matching connection of both ends of the above-mentioned components. And when there is 1 group of the above-mentioned components, it effectively reflects the same-number installation of the above-mentioned components with respect to the connecting cross pipe 101. At the same time, 3 groups of limiting ring grooves 202 are hierarchically opened inside a single installation cylinder 201. When the 3 groups of limiting ring grooves 202 are used, it effectively plays a sliding adjustment and limiting effect on the hollow adjusting pipes 204 arranged at both ends. At the same time, the installation cylinders 201 are elastically adjusted with the hollow adjusting pipes 204 through installation springs 203. The overall shape of the hollow adjusting pipe 204 is arranged in a "T" shape. When the overall shape of the above-mentioned components is arranged in a "T" shape, it not only reflects the fixed installation of one end of the above-mentioned components with the connecting cross pipe 101, but also reflects the sliding matching connection of the other end of the above-mentioned components with the installation cylinder 201. And when the overall shape of the above-mentioned components is arranged in a "T" shape, it also reflects the internal fixed opening of the above-mentioned components and the fixed connection of the bottom with one end of the installation spring 203.

[0032] Furthermore, in the above solution, the hollow adjusting pipe 204 is provided with a connecting hole 205 through it, and a connecting rod 206 is fixed inside the hollow adjusting pipe 204. At the same time, the connecting rod 206 is fixedly connected in a wrapped manner above the spring bracket 207. The overall shape of the spring bracket 207 is in a "U" shape. When the overall shape of the above components is in a "U" shape, not only does the above component have a semi-wrapping and fixing property for the connecting rod 206, but also the fixing and installation properties on both sides at the bottom of the above component are reflected. And when the overall shape of the above components is in a "U" shape, the axial symmetry of the above components and the elastic squeezing and adjusting property of synchronous force on both sides are reflected. At the same time, when the overall shape of the above components is in a "U" shape, the elastic recovery property of the installation and setting of the above components is reflected.

[0033] Furthermore, in the above solution, connecting pins 208 passing through the connecting hole 205 are fixed on both sides of the spring bracket 207, and the connecting pins 208 are connected in a limited way with the limit ring groove 202. The hollow adjusting pipe 204 is fixedly welded with the connecting cross pipe 101, and a weight-reducing hole 102 is also provided through the hollow adjusting pipe 204. Among them, the above components form an elastic adjusting structure. When using the elastic adjusting structure formed by the above components, it effectively performs elastic squeezing and receiving and elastic extension and contact limiting on the connecting pin 208.

[0034] In the above solution, when the operator pulls the connecting cross pipe 101 to drive the hollow adjusting pipe 204 to move under force, during the process of the hollow adjusting pipe 204 moving under force, the mounting spring 203 is driven to be pulled under force. At this time, the hollow adjusting pipe 204 synchronously drives the connecting pin 208 to slide inside the mounting cylinder 201. When the connecting cross pipe 101 is adjusted to a corresponding horizontal distance, at this time the connecting pin 208 is connected and limited with the limit ring groove 202. When it is necessary to change the horizontal length after the connecting cross pipe 101 is pulled, at this time the operator pulls the connecting cross pipe 101 again to separate the connecting pin 208 from the limit ring groove 202 under force, and then the operator pushes the connecting cross pipe 101 to drive the connecting pin 208 to move downward to change the horizontal distance of the connecting cross pipe 101.
