A needle-type dispensing head 214 is engaged at the lower end of the tube 212. As needed, the electric lifting rod 202 is activated, causing it to lift and lower the moving top plate 203, thus positioning the storage tank 209 within the limiting and stabilizing ring 204. The heating strip 210 inside the storage tank 209 is activated to raise the temperature inside the anti-stick inner cylinder 211, preventing the adhesive from being affected by temperature changes during application.
