Multiple groups of the first worm assembly 8 are coaxially rotatably connected in sequence through multiple groups of No. 1 transmission rod groups 13;

[0037] The mounting bracket 4 is fixedly mounted on one end of the rotary tube 2 away from the mounting plate Ⅰ101, a rotary shaft 17 is rotatably mounted in the mounting bracket 4, the rotary shaft 17 is transmission-connected to a movable tube 3 slidably mounted in the rotary tube 2 through a gear assembly 10, an externally threaded tube 11 is rotationally connected to the side of the movable tube 3 away from the rotary shaft 17, the externally threaded tube 11 is slidably mounted on a limit bracket 15 mounted on the mounting plate Ⅰ101, the externally threaded tube 11 and a rotary nut 12 rotatably mounted on the limit bracket 15 form a spiral pair transmission, the limit bracket 15 is provided with a second worm assembly 9 for driving the rotary nut 12 to rotate, and multiple groups of the second worm assemblies 9 are coaxially rotationally connected in sequence through multiple groups of No. 2 transmission rod groups 14;

[0039] Specifically, in the present invention, the number of the mounting plate groups 1 can be selected according to the number of glue dispensers. For example, the number of the mounting plate groups 1 in the present invention is four, and correspondingly, four groups of glue dispensers can be installed thereon to perform glue dispensing operations.

[0041] Furthermore, in the mounting plate group 1 described in the present invention, the distance between the mounting plate I101 and the mounting plate II102 is adjusted by the extension and retraction of the telescopic link 7. The number of the telescopic links 7 described in the present invention is two groups, and the two groups of telescopic links 7 are respectively connected to the two ends of the mounting plate I101 and the mounting plate II102.

When the rotary shaft 17 rotates, the externally threaded tube 11 and the second worm assembly 9 located on the mounting plate Ⅰ101 drive the movable tube 3 to slide linearly along the axial direction of the rotary tube 2. At the same time, the transmission rack 1001 located on one side of the movable tube 3 meshes and drives the transmission gear 1002 and the rotary shaft 17 to rotate, thereby driving the mounting seat 5 to rotate and realizing the application angle adjustment of the glue dispenser around the axial direction of the rotary shaft 17.

The No. 1 transmission rod group 13 and the No. 2 transmission rod group 14 can complete the transmission operation. When the spacing between the mounting plate I101 and the mounting plate II102 is adjusted, the No. 1 transmission link 1302 and the No. 2 transmission link 1402 can synchronously adjust their lengths to perform corresponding adaptation operations. The No. 1 transmission link 1302 and the No. 2 transmission link 1402 described in the present invention are both prior arts.
