[0003]

[Problems to be solved by the invention]

 However, this type of sand spray gun has the following problems. 1. Although the sand spray main body 12 cannot be rotated due to the restriction of the locking piece 121, it can be said that it is an advantage, but other functions are also limited, and this kind of sand spray gun 10 has a suction type structure. Applicable only to gravitational structures that flow from top to bottom. 2. With regard to the screwing of the nozzle 13, the nozzle 13 has a special shape and extends into the sand spray body 12, where the nozzle 13 is tightened. Furthermore, since the space inside the sand spray main body 12 is narrow, the tool for stopping the nozzle 13 is also specially designed, and the tool is exclusive to the manufacturing plant. This makes it impossible for consumers to remove them themselves, which is also the aim of the manufacturer and that consumers are not allowed to remove it freely. Therefore, the nozzle 13 is gradually damaged, and finally the sand spray gun 10 is disposable and must be replaced anew. 3. The aforementioned sand spray gun 10 has a limited length of its tube 16 and is generally about 2 meters. This is mainly due to the lack of suction power, which limits the working range of the sand spray gun and has no effect when working on small ones. (Especially large machine frames) require several sets of sand spray guns. 4. In view of the roughness of the sand particles used for the sand spray, relatively fine particles are sucked into the main body 12 by a suction force. No, the sand spray function cannot be used. 5. Since the sand spray gun 10 has only the sand spray function, the same type of cleaning gun and simple paint spray gun must be purchased separately, which is inconvenient.

[0004] An object of the present invention is to provide a spray tool gun device that integrates a sand spray function, a cleaning function, and a simple spray paint function, eliminates duplicate purchases, and reduces machine cost.

Another object of the present invention is to make it easy to remove the jet joint, and to allow the user to replace, clean, and care for the damaged jet joint at any time. An object of the present invention is to provide a spray tool gun device for extending the service life of a product.

[0006] Still another object of the present invention is to arrange the connecting stand in the jet joint by rotating 360 degrees so that it can be arranged at an arbitrary angle or downward or upward, and the state of the jet can be sucked up or gravity. It is an object of the present invention to provide a spray tool gun device which can be changed according to the demands of work by making it into a formula.

Another object of the present invention is to provide a connecting table having a jet joint, which can be connected to a pipe joint, can be connected to a long pipe (possible to a length of up to 25 meters), and has a cylindrical sand. It can also be applied to storage cylinders and connection with paint cans.When spraying, when using coarse particles or high concentration liquid, it can be changed to gravity type, increasing the efficiency of sand spray and liquid spray An object of the present invention is to provide a spray tool gun device.
