Technical Field

[0001] This utility model relates to the field of glue gun technology, and in particular to a glue-applying tool that is easy to operate with one hand. Background Technology

[0002] A glue gun is a tool for applying or extruding glue. It is widely used in industries such as building decoration, electronics, automobiles and auto parts, ships and containers. Based on the force applied, glue guns can be classified as manual glue guns, pneumatic glue guns, and electric glue guns. Electric glue guns are powered by rechargeable batteries and are equipped with a charger and rechargeable batteries. They can automatically apply glue and easily complete large-volume glue application tasks.

[0003] A search revealed a glue-applying tool for construction, patent publication number CN218742971U. The tool includes a glue tube, a driver, a pusher, a front cover, a nozzle, and a handle. The glue tube is a hollow cylinder containing glue. The driver is located at one end of the glue tube. The pusher consists of a disc, a push rod, and a suspension component. One end of the push rod is connected to the center of the disc, and the other end is connected to the suspension component. One end of the driver is inserted into the glue tube, and the driver drives the pusher to slide within the glue tube. The front cover is located at the other end of the glue tube and is detachably connected to it. The nozzle is located at the other end of the glue tube and connected to it via the front cover, used to extrude glue to a preset position. The handle is located at the bottom of the glue tube.

[0004] In the process of implementing the above solution, the following problems were found in the existing technology that have not been well resolved: the existing glue application tools cannot be well adapted to the arm, and both hands are still required to operate when applying force, resulting in low work efficiency and low glue application quality. Therefore, it is urgent to design a glue application tool that is easy to operate with one hand to solve the above problems. Utility Model Content

The entire glue applicator is supported by the support plate 11, the buffer assembly 12 and the pulleys 13, so that the force applied to the entire glue applicator is fully utilized and the stability of the entire glue applicator is guaranteed.

[0036] To ensure the stability of the nozzle, refer to Figure 1 , Figure 6 and Figure 7 The reinforcing component 14 includes an annular frame 1401 fixed to the other end of the housing 1. The inner wall of the annular frame 1401 has equally spaced inlets and outlets 1406. Clamping seats 1403 are inserted into the inner walls of each inlet and outlet 1406. Equally spaced toothed grooves are formed on one side of each clamping seat 1403. Equally spaced toothed pillars 1404 are rotatably arranged on the inner wall of the annular frame 1401, meshing with the toothed grooves. A toothed ring 1402 is rotatably arranged on the inner wall of the annular frame 1401, meshing with the toothed pillars 1404. An installation hole is provided on the annular frame 1401, and a threaded rod 1408 is rotatably arranged on the inner wall of the installation hole. One end of 1408 is fixed with a second knob 1405. One of the clamping seats 1403 has a threaded hole 1407, and the threaded hole 1407 is screwed to the threaded rod 1408. The second knob 1405 in the reinforcing assembly 14 drives the threaded rod 1408 to rotate. The screwing action of the threaded rod 1408 and the threaded hole 1407 is used to adjust the position of the clamping seat 1403 in the inlet and outlet 1406. With the meshing action of the tooth groove and the tooth column 1404 and the meshing action of the tooth column 1404 and the tooth ring 1402, the position of all clamping seats 1403 is adjusted. In this way, the clamping seats 1403 are used to reinforce the nozzle on the rubber tube to prevent the nozzle from falling off.

[0037] Working principle: In use, the user places the rubber tube into the housing 1, then installs the nozzle at one end of the rubber tube. The second knob 1405 in the reinforcing assembly 14 rotates the threaded rod 1408, adjusting the position of the clamping seat 1403 within the inlet / outlet 1406 through the screw connection between the threaded rod 1408 and the threaded hole 1407. This, combined with the meshing of the toothed groove and toothed column 1404, and the meshing of the toothed column 1404 and toothed ring 1402, adjusts the position of all clamping seats 1403, thus reinforcing the nozzle on the rubber tube. The user then holds the handle frame 7, ensuring the arm guard 5 fits snugly against their arm. This enables one-handed operation. When the forward / reverse shift switch 10 starts the driver 18 to rotate forward, it drives the rotating rod, transmission wheel, drive belt 21 and I-shaped rotating base 25 to rotate. In conjunction with the screw hole and the screwed connection of the push screw 3, the push screw 3 moves in the first through hole 15, which in turn moves the push plate 23, thus achieving electric glue dispensing performance. Then, when the entire glue dispensing tool is pulled to dispense glue, the two pulleys 13 slide at the corner of the glue dispensing area. The support plate 11, buffer assembly 12 and pulleys 13 support the entire glue dispensing tool, so that the pressure applied to the entire glue dispensing tool is fully utilized, ensuring the stability of the entire glue dispensing tool.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
