[0029] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0030] like Figure 1-7 As shown, a portable toner replenishing tool comprises a support box 1, two groups of arm assemblies 2 symmetrically arranged at both ends of the support box 1, and a central support assembly 3 detachably installed at the center of the support box 1.

[0031] See attached Figure 2-4 , wherein an inner support plate 11 is integrally formed at the center of the support box 1, and track grooves 14 are staggered transversely at both ends of the support box 1;

[0032] In contrast, the arm assembly 2 includes a bottom arm 21 and a movable arm 22 slidably connected to the inside of the bottom arm 21 , and a fixing claw 23 is fixedly installed on the top of the bottom arm 21 ;

[0033] In order to connect with the support box 1, an extension leg 211 is integrally formed at the bottom end of one group of bottom support arms 21, and a cylindrical slide 212 is fixedly installed at the bottom end of the extension leg 211 and the other group of bottom support arms 21, thereby forming two groups of cylindrical slides 212 with staggered heights at both ends of the support box 1, so that the two groups of cylindrical slides 212 can be slidably connected to the inside of the track groove 14 respectively. In this way, when the two groups of support arm assemblies 2 rotate in opposite directions around the cylindrical slides 212 thereon, they can be rotated and embedded in the top and bottom surfaces of the support box 1, and at the same time be isolated by the inner support plate 11. The difference is that one group of support arm assemblies 2 that drives the extension legs 211 needs to rotate 270°, and the other group only needs to rotate 90° to complete folding and storage, which is convenient for staff to carry and move;

[0034] Furthermore, in order to prevent the inner support plate 11 from hindering the lateral movement of the extended support leg 211, a limited edge groove 12 is provided between the two ends of the inner support plate 11 and the inner wall of the support box 1, so that the two groups of support arm assemblies 2 will not be blocked by the inner support plate 11 when moving in opposite directions to change the support width. At the same time, the bottom surface of the bottom support arm 21 is attached to the top surface of the inner support plate 11, which can limit it, so that it will not rotate during the lateral movement, thereby maintaining the stability of the support;

[0035] See attached Figure 2-3 In order to detachably install the central support component 3, a plum blossom through hole 13 is opened in the center of the inner support plate 11. At the same time, the central support component 3 includes a threaded column 31, a threaded sleeve 33 threadedly connected to the top of the threaded column 31, and a supporting claw 34 fixedly installed on the top of the threaded sleeve 33. A plum blossom support 32 adapted to the plum blossom through hole 13 is fixedly installed at the bottom of the threaded column 31. When in use, the plum blossom support 32 can be used to install it in the plum blossom through hole 13, and the threaded sleeve 33 can be manually rotated to change the support height; when storing, it can be pulled out of the plum blossom through hole 13, which is convenient for the device to be folded and stored.

[0036] See attached Figure 2-4 In order to automatically adjust the support width of the two groups of arm assemblies 2, a first servo motor 15 is fixedly installed on the inner side of one end of the support box 1, and synchronous wheels 17 are symmetrically rotated and connected on the outer sides of the two ends of the support box 1, and a synchronous belt 19 is connected around the two groups of synchronous wheels 17, and a first driven gear 18 is fixedly installed on the inner side of one of the synchronous wheels 17. By fixing a first driving gear 16 on the power output end of the first servo motor 15 and meshing the first driving gear 16 with the first driven gear 18, the first servo motor 15 can drive the first driving gear 16 to rotate, and the first driving gear 16 is meshed with the first driven gear 18 to drive the synchronous wheel 17 to rotate, thereby driving the synchronous belt 19 to rotate;

[0037] Furthermore, by rotating and connecting the connecting plates 213 on the two groups of cylindrical slides 212 close to the synchronous belt 19, the height difference between the two groups of connecting plates 213 can be used to stagger and fix them on the top and bottom surfaces at both ends of the synchronous belt 19, so that when the synchronous belt 19 rotates, the two groups of support arm assemblies 2 can be driven to move synchronously toward each other along the track groove 14 to change the support width.

[0038] See attached Figure 4-6In order to automatically adjust the support height of the support arm assembly 2, a lead screw 26 is rotatably connected between the bottom support arm 21 and the movable support arm 22 through a bearing seat, and a nut seat 27 is threadedly connected to the lead screw 26. A second servo motor 28 is fixedly installed at the bottom end of the bottom support arm 21, and the nut seat 27 is fixedly installed at the bottom end of the movable support arm 22. At the same time, a second driving gear 29 is fixedly installed at the power output end of the second servo motor 28, and a second driven gear 210 meshing with the second driving gear 29 is fixedly installed at the bottom end of the lead screw 26. The second servo motor 28 can drive the second driving gear 29 to rotate, and the second driving gear 29 is meshed with the second driven gear 210 to drive the lead screw 26 to rotate, so that the nut seat 27 threadedly connected on its surface moves along the lead screw 26, thereby driving the movable support arm 22 to telescope up and down relative to the bottom support arm 21 to change the support height;

[0039] Furthermore, in order to ensure the telescopic stability of the movable support arm 22 and the bottom support arm 21, limiting grooves 24 are symmetrically opened on both sides of the movable support arm 22, and a limiting block 25 is fixedly welded on the inner wall of the top end of the bottom support arm 21. By sliding the limiting block 25 into the limiting groove 24, the telescopic movement of the movable support arm 22 and the bottom support arm 21 can be limited, and the telescopic process is more stable.

[0040] See attached Figure 4-6 In this embodiment, in order to provide power to the electronic components, a battery module 4 is also provided, which is fixedly mounted on a side of the support box 1 away from the synchronous belt 19. At the same time, a control module 41 for providing a control function is provided at the center of the battery module 4, so that the staff can adjust the support height and width conveniently;

[0041] Furthermore, in order to protect the synchronous belt 19, the present embodiment is also provided with a protective shell 5, which covers and wraps the synchronous belt 19 and is fixedly connected to the side of the support box 1, so as to wrap and protect the synchronous belt 19 and its surrounding components to avoid damage during movement.

[0042] The working principle of the utility model is as follows: when in use, first, the control module 41 can be used to control the first servo motor 15 to drive the first driving gear 16 to rotate, and the first driving gear 16 is meshed with the first driven gear 18 to drive the synchronous wheel 17 to rotate, thereby driving the synchronous belt 19 to rotate, and then the connecting piece 213 can be used to drive the two groups of support arm assemblies 2 to move synchronously toward each other along the track groove 14 to change the support width;

[0043] Secondly, the second servo motor 28 can be controlled by the control module 41 to drive the second driving gear 29 to rotate, and the second driving gear 29 is meshed with the second driven gear 210 to drive the lead screw 26 to rotate, so that the nut seat 27 threadedly connected on its surface moves along the lead screw 26, thereby driving the movable support arm 22 to move up and down relative to the bottom support arm 21 to change the support height. At the same time, the support height of the support claw 34 can be adjusted by manually rotating the threaded sleeve 33, so that toner cartridges of different widths can be installed, which is convenient for the replenishment of toner;

[0044] Finally, after the carbon powder is added, the plum blossom support 32 can be directly pulled out from the plum blossom through hole 13 to separate the central support assembly 3 from the support box 1. At the same time, the length of the arm assembly 2 and the position relative to the support box 1 are reset. Then, a group of arm assemblies 2 with extended legs 211 are rotated 270° relative to the support box 1 and hidden at the bottom of the support box 1. At the same time, the other group of arm assemblies 2 are rotated 90° in the opposite direction and hidden at the top of the support box 1. The device is completely folded for easy carrying by staff.

[0045] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
