Portable USB leakage preventing glue gun

Abstract

The invention relates to a portable USB leakage preventing glue gun. The portable USB leakage preventing glue gun comprises an outer shell I and an outer shell II. The outer shell I and the outer shell II are fixedly connected to form a cavity, and a trigger assembly is arranged at the upper portion of the cavity. The trigger assembly is provided with a vertical fixing hole, and cylindrical adhesive tape fixedly penetrates the hole. Silica gel II is arranged at the connecting position of the adhesive tape and an inlet of the fixing hole of the trigger assembly, and return force silica gel I is arranged at the connecting position of the adhesive tape and an outlet of the fixing hole of the trigger assembly. Meanwhile, the end portion of the adhesive tape is fixed into a heating assembly with a hot melt adhesive nozzle. The bottom of the outer shell I is connected with a USB power line. A fixing iron wire frame is arranged on a shell on the periphery of the heating assembly. The portable USB leakage preventing glue gun has the beneficial effects that convenience is improved; the awkward situation that glue residues can leak in common glue guns is thoroughly avoided; the size of the whole glue gun becomes small; and the moving position of a rear glue bar is avoided.

Description

technical field [0001] The invention relates to a gluing tool, in particular to a portable USB leak-proof glue gun. Background technique [0002] A glue gun is a tool for making glue (or squeezing glue), which can be used when glue is needed. It is widely used in industries such as architectural decoration, electronic appliances, automobiles and auto parts, ships and containers. In terms of force: manual glue gun, pneumatic glue gun, electric glue gun, manual glue gun: the operator presses the plate by hand to apply glue, and the efficiency of glue application is low; pneumatic glue gun: needs to be connected to a compressed air source, The air pushes the bottom of the glue to realize the glue; the air source (from the factory's air compressor station or air compressor through the air pipe). [0003] At present, the high-quality pneumatic glue guns on the market are equipped with silencers, which are suitable for indoor workplaces that require quietness. The air pressure ca...

Problems solved by technology

[0004] This case points out in combination with the actual situation that there are still many problems to be solved in many unsolved problems and expandable technical links: first, the current industrial or household glue guns (after the PU glue strips are melted, used for Filling or sticking tools), most of them work on the AC socket, which is limited by the location of the AC socket and cannot work without power. At the same time, it is also limited by the length of a very thick power cord; Second, even if there are some glue guns that use DC power supply, they are heavy and bulky due to the weight limit of large dry batteries, which is very inconvenient to use; third, the existing glue guns even leak glue. When the glue gun is released (when the glue gun is released to squeeze the trigger), glue will still flow out continuously. A plate must be placed under the mouth of the glue gun to collect the leaked residual glue, which is a waste of glue and troublesome to deal with.
