Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a rotary glue gun with a quick nozzle replacement. Background Art

[0002] A glue gun is a tool used to apply hot melt glue or other glue, usually consisting of a heating element and a pressure system. When using a glue gun, the glue stick is heated and melted in the heating element of the glue gun, and the glue is squeezed out of the nozzle by pulling the trigger to glue objects or fill gaps;

[0003] The nozzle of the glue gun is often easily clogged and needs to be replaced with a new one. Traditional glue guns usually have a fixing screw or clamping mechanism, which makes it inconvenient to remove the old nozzle. Utility Model Content

[0011] Preferably, the support ring is stepped, and the outer diameter of the end of the support ring close to the output head is smaller.

[0012] In order to facilitate and stabilize glue discharge, the utility model is improved in that the end of the output head away from the glue gun body is tapered.

[0013] (III) Beneficial effects

[0014] Compared with the prior art, the utility model provides a rotary glue gun with quick nozzle replacement, which has the following beneficial effects:

[0015] The rotating glue gun can quickly replace the nozzle. The fixing block is in the shape of a quarter sphere. During assembly, the output head of the glue gun body is plugged into the support ring, and the nozzle cannot be unplugged at this time. When the nozzle needs to be unlocked, it is only necessary to rotate the nozzle to misalign the fixing block with the card slot of the output head to unlock the nozzle. It is easy to use.
