[0022] It should be noted here that: by setting up the detection component, it is convenient to detect the inclination of the placement frame 103. At the same time, the adjustment component is used to balance the force on both sides of the unbalanced weight of the placement frame 103, thereby preventing the placement frame 103 from tilting, further ensuring the stability of the metal frame during use, thereby avoiding the falling damage of the assembly accessories and the injury to the user caused by the tipping of the metal frame, thereby improving the safety of the use of the metal frame.

[0023] See also Figure 3, in the illustrated figure, the detection component includes a plurality of detection tubes 401 rotatably connected to the side wall of the adjusting rod 102. Each pair of the detection tubes 401 is arranged opposite to each other. A detection rod 402 is slidably connected to each detection tube 401. One end of each detection rod 402 away from the adjusting rod 102 is connected to the placement frame 103 through a connection component. The other end of the detection rod 402 is located inside the detection tube 401 and is fixedly connected to a detection plate 403. A distance sensor 405 is provided at one end of the detection tube 401 away from the adjusting rod 102. The detection end of the distance sensor 405 is arranged opposite to the detection plate 403. A first spring 404 is sleeved on the side wall of the detection rod 402 inside the detection tube 401. Two ends of the first spring 404 are respectively connected to the detection plate 403 and the inner wall of the detection tube 401;

[0024] It should be noted here that: through the setting of the detection component, it is convenient to detect the inclination of the placement frame 103.

[0025] It is worth noting that: the model of the distance sensor 405 is AC-M18-A50 / 100. As an existing technology, its specific structure and working principle have been mastered by those skilled in the art, and will not be elaborated here.

[0026] Please refer to Figure 2 , in the illustrated figure, the connection component includes a connecting rod fixedly connected to the side of the placement frame 103 close to the adjusting rod 102. One end of the connecting rod away from the placement frame 103 is fixedly connected to a connecting ball 501. A connecting block 502 is rotatably connected to the side wall of the connecting ball 501. One end of the detection rod 402 away from the adjusting rod 102 is connected to the connecting block 502;

[0027] It should be noted here that: through the setting of the connection component, the inclination of the placement frame 103 can be reflected to the detection component.

[0028] Working principle: When this metal rack is in use, the height of the placement frame 103 can be adjusted by adjusting the height of the adjusting rod 102, thereby improving the flexibility and convenience of using this metal rack. Moreover, each component such as the support tube 101, the adjusting rod 102, each support rod 105, and the placement frame 103 is made of high-strength alloy steel, thereby improving the strength of this metal rack during use;

[0029] After the height adjustment of the placement frame 103 is completed, the accessories to be used can be placed in the placement frame 103, so as to facilitate the taking of the accessories during the production and assembly process. In the process of continuous taking, when the accessories of the placement frame 103 are tilted due to excessive weight on one side due to the randomness of taking, the detection rod 402 located on the lighter side of the placement frame 103 will be pulled away from the adjustment rod 102. During the movement of the detection rod 402, the detection plate 403 will be driven to move in the detection tube 401. During the movement of the detection plate 403, when the distance sensor 405 detects that the movement distance of the detection plate 403 exceeds the set limit position, an electrical signal will be sent to the controller. Under the control of the controller, the adjustment component will be used to balance the force on both sides of the unbalanced weight of the placement frame 103, thereby preventing the placement frame 103 from tilting, further ensuring the stability of the metal frame during use, thereby avoiding the fall and damage of the assembly accessories and the injury to the user caused by the tipping of the metal frame, thereby improving the safety of the use of the metal frame.

[0030] Example 2

[0031] See also Figure 3 , this embodiment further explains Example 1, the adjustment assembly shown in the figure includes an adjustment shaft 601 rotatably connected to the detection tube 401, the adjustment shaft 601 is located on the side wall inside the detection tube 401 and is fixedly connected to a winding drum 602, the winding drum 602 is wound with a pull rope 603, one end of the pull rope 603 is connected to the winding drum 602, and the other end of the pull rope 603 is connected to the detection plate 403;

[0032] It should be noted here that: through the setting of the adjustment component, when the placement frame 103 is tilted due to uneven weight distribution of the object, the detection plate 403 will move in the detection tube 401, thereby further driving the pull rope 603 to be pulled out from the winding drum 602. At this time, under the detection action of the detection component, when it is detected that the placement frame 103 is tilted, the motor 604 will be started to drive the adjustment shaft 601 to rotate, thereby further driving the winding drum 602 to rotate. During the rotation of the winding drum 602, the pull rope 603 is wound up, thereby further pulling the detection plate 403, so that the detection rod 402 provides a pulling force to the lighter side of the placement frame 103, so that the two sides of the unbalanced weight of the placement frame 103 maintain a balanced force, thereby further preventing the placement frame 103 from tilting.

[0033] See also Figure 4 , the side wall of the detection tube 401 shown in the figure is provided with a motor 604, the output end of the motor 604 is connected to the adjustment shaft 601, and the motor 604 is a common stepping motor;

[0034] It should be noted here that: by setting the motor 604, it is convenient to drive the adjusting shaft 601 to rotate, so as to facilitate the winding of the pulling rope 603. And since the motor 604 is an ordinary stepper motor and lacks a brake device to lock the output shaft, therefore, after the motor 604 is powered off, the adjusting shaft 601 will not be locked, so that the adjusting shaft 601 is in a rotating state, and further, the pulling rope 603 can be stretched to adapt to the movement of the detection plate 403. At the same time, after the motor 604 is powered on, it will connect and fix the adjusting shaft 601, so as to facilitate the rotation of the adjusting shaft 601.

[0035] Embodiment 3

[0036] Please refer to Figure 3 , this embodiment further explains other embodiments. The detection tube 401 in the figure is provided with a tensioning assembly for tensioning the pulling rope 603. The tensioning assembly includes a tensioning plate 701 arranged on the side of the detection tube 401 away from the motor 604. One end of the adjusting shaft 601 close to the tensioning plate 701 penetrates through the detection tube 401 and is connected to the tensioning plate 701. A torsion spring 702 is sleeved on the outer side wall of the detection tube 401 where the adjusting shaft 601 is located. The two ends of the torsion spring 702 are respectively connected to the tensioning plate 701 and the detection tube 401;

[0037] It should be noted here that: through the setting of the tensioning assembly, by using the elastic action of the torsion spring 702, after the motor 604 is powered off, the pulling rope 603 can be kept in tension, so as to adapt to the movement requirement of the detection plate 403 while facilitating the motor 604 to drive the adjusting shaft 601 to rotate immediately after being powered on, so as to drive the winding of the pulling rope 603.
