[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 This utility model provides an embodiment of a multi-purpose hot melt glue gun, including a gun holder 1. The gun holder 1 is made of robust engineering plastic, ensuring sufficient strength to support the entire structure of the hot melt glue gun while maintaining a light weight for easy carrying and operation. A frame 2 is connected to the top of the gun holder 1. The frame 2 is made of high-strength aluminum alloy to ensure it will not easily deform during use. A push rod 3 is slidably connected inside the frame 2. The push rod 3 is made of stainless steel, possessing good wear resistance and corrosion resistance, and maintaining stable pushing performance during prolonged use. A telescopic spring 6 is fixedly connected to the rear end of the push rod 3. The telescopic spring 6 is made of high-quality spring steel, possessing good elasticity and durability, and maintaining stable performance during repeated stretching and compression. A sliding column 4 is fixedly connected to the rear end of the push rod 3. The sliding column 4 is also made of stainless steel and can slide smoothly inside the frame 2, providing stable guidance for the movement of the push rod 3.

[0032] A connecting post 8, made of sturdy metal, is fixedly connected to the front end of frame 2, securely connecting frame 2 and rotating disk 9 to ensure the stability of the entire structure. The rotating disk 9, made of high-strength plastic, is rotatably connected to the outside of the connecting post 8, with internal slots 10 for storing multiple glue sticks 11. Glue sticks 11, made of high-quality hot melt adhesive, are slidably connected inside the rotating disk 9, melting rapidly upon heating to provide strong adhesion. A fixed post 5, made of stainless steel, is slidably connected inside the sliding post 4, providing stable support for the telescopic spring 6 and ensuring it does not shift during operation. A heating block 12, using a high-efficiency heating element, is fixedly connected to the front end of the connecting post 8, rapidly heating the glue sticks 11 to a molten state. A replacement assembly for quick replacement is located at the rear end of the heating block 12.

[0033] The other end of the telescopic spring 6 is fixedly connected to the inside of the frame 2. The telescopic spring 6 is sleeved on the outside of the sliding column 4 and can be compressed when the push rod 3 slides backward. When the hand is released, the telescopic spring 6 can quickly release energy, pushing the push rod 3 to slide inside the frame 2 and the rotating disk 9, so that the push rod 3 abuts against the rear end of the glue stick 11. This automatic push design for melting the glue stick 11 greatly reduces the unnecessary time spent by the staff when changing and using it, and improves work efficiency. The front end of the sliding column 4 is fixedly connected to the push rod 7. The push rod 7 is made of plastic and has a smooth exterior, which facilitates sliding in the groove opened on the outside of the gun holder 1. The gun holder 1 has a groove on its exterior, and the push rod 7 is slidably connected to the inside of the groove. The staff can easily and quickly change the glue stick 11 by pulling the push rod 7 to slide inside the frame 2. The gun holder 1 has a rotating connection to the inside of the gun holder 1. The push rod 18 is made of plastic and has a good feel and operation performance. The bottom of the gun holder 1 is fixedly connected to a power cord 19. The power cord 19 is made of high-quality rubber material, which has good flexibility and wear resistance, and can provide a stable power supply for the hot melt glue gun.

[0034] Reference Figure 1 and Figure 4The replacement components include a fixed housing 15, with a dispensing head 17 slidably connected to its front end. The fixed housing 15 is made of high-strength plastic, providing stable fixation and support for the dispensing head 17. The front end of the fixed housing 15 is fixedly connected to the rear end of the heating block 12 to ensure the stability of the dispensing. A rotating block 13 is rotatably connected to the outside of the fixed housing 15. The rotating block 13 is made of plastic and has anti-slip textures on its exterior for easy rotation by the operator. Two pressure blocks 14 are fixedly connected inside the rotating block 13. The pressure blocks 14 are made of rubber, providing good elasticity and friction, and can compress or release the clamping block 16 under the action of the rotating block 13. A clamping block 16 is slidably connected inside the fixed housing 15. The clamping block 16 is made of metal, providing good strength and stability, and can fix or release the dispensing head 17 under the action of the pressure blocks 14.

[0035] The fixed housing 15 has a groove on its exterior, and the pressure block 14 is slidably connected inside the groove to ensure stable movement of the pressure block 14. The dispensing head 17 is made of high-temperature resistant plastic, which can maintain stable performance under the high-temperature environment of the heating block 12. The pressure block 14 is externally coupled to the top of the clamping block 16. When the operator needs to replace the dispensing head 17, by rotating the rotating block 13 on the exterior of the fixed housing 15, the pressure block 14 is released from the clamping block 16, and the clamping block 16 is released from fixing the dispensing head 17. Pulling the dispensing head 17 outward completes the disassembly. At this time, another dispensing head 17 is taken out and slid into the interior of the fixed housing 15. Then, by rotating the rotating block 13 in the opposite direction, the pressure block 14 squeezes the clamping block 16 to slide inside the fixed housing 15, thereby completing the fixing of the dispensing head 17. This design of quick dispensing head replacement can meet the needs of operators in different working directions and improve the practicality and flexibility of the hot melt glue gun.

[0036] Working principle: When the glue stick 11 is used up, the operator can slide the push rod 7 inside the frame 2. When it slides to the bottom, the rotating disk 9 is rotated so that the new glue stick 11 is aligned with the hole inside the heating block 12. At this time, the operator releases the hand, and the telescopic spring 6 pushes the push rod 3 to slide inside the frame 2 and the rotating disk 9, so that the push rod 3 abuts against the rear end of the glue stick 11. At this time, the operator has completed the quick filling of the glue stick 11. The push rod 3 will continue to push the glue stick 11 to slide during the use of the glue gun, thereby automatically pushing the glue stick 11 to melt. Through quick replacement and loading, unnecessary time consumption during replacement and use is reduced, and work efficiency is improved.

[0037] When workers need to achieve different working directions and need to change the dispensing head 17, they can rotate the rotating block 13 outside the fixed shell 15 to release the pressure block 14 from the clamping block 16, thus releasing the clamping block 16 from fixing the dispensing head 17. Pulling the dispensing head 17 outward completes the disassembly. Then, another dispensing head 17 can be taken out and slid into the fixed shell 15. By rotating the rotating block 13 in the opposite direction, the pressure block 14 squeezes the clamping block 16 to slide inside the fixed shell 15, thereby fixing the dispensing head 17. By quickly changing the dispensing head 17, different processing needs can be met, improving processing efficiency.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
