[0022] From the above description, it can be seen that the beneficial effects of the utility model are:

[0023] When the utility model is spraying and displaying paint, paints of multiple colors can be loaded into the paint cans respectively and installed on the placement component, and then the external threaded sleeve and the rotating rod are driven by the forward and reverse driving motors to rotate forward and reverse in turn, so as to realize the up and down lifting of the suction tube and the switching of the position of the paint can respectively, so that different colors of paint can be sprayed and displayed in turn, and there is no need to frequently disassemble and replace the paint cans, thereby improving the display efficiency of the paint, and the up and down lifting of the suction tube and the switching of the position of the paint can are controlled by the same set of driving motors, which reduces the cost of the equipment.

[0024] Furthermore, the bevel gear assembly includes a rotating disk fixedly connected to the outer wall of the rotating rod, a plurality of pawls are fixedly connected at equal angles to one side of the rotating disk, the outer wall of the rotating disk is sleeved with an inner ratchet bevel gear that cooperates with the pawls, and the inner ratchet bevel gear is meshed and connected with the incomplete active bevel gear, and the bottom of the inner ratchet bevel gear is rotatably connected to the top of the external threaded sleeve via a rotating bearing.

[0025] From the above description, it can be seen that through the mutual cooperation between the inner ratchet bevel gear and the pawl, the rotating rod can be driven to rotate when the driving motor rotates in the forward direction, but cannot be driven to rotate when the driving motor rotates in the reverse direction, thereby realizing the directional rotation of the rotating rod, and the setting of the rotating bearing can support and fix the inner ratchet bevel gear.

[0026] Furthermore, the placement assembly includes a placement plate connected to the rotating rod, a placement seat with a groove is installed at an equal angle on the top of the placement plate, and rubber columns are arranged at an equal angle on the side wall of the inner cavity of the placement seat.

[0027] It can be seen from the above description that the position of the paint tank can be limited by the placement seat, and the provision of the rubber column can play a centering role for the paint tank.

[0028] Furthermore, the straw comprises a telescopic bellows, the bottom of which is connected to a straight tube with a suction head, and the straight tube passes through a pressing plate, and the top of the telescopic bellows is connected to a connecting tube.

[0029] It can be seen from the above description that when the pressure plate slides up and down, the extension and retraction of the straw can be achieved through the extension bellows.

[0030] Furthermore, a rubber plug corresponding to the opening of the paint tank is arranged at the bottom of the pressing plate, and the rubber plug is inserted into the opening of the paint tank, and one end of the straw passes through the rubber plug.

[0031] From the above description, it can be known that when the pressing plate is pressed down to contact the paint can, the rubber plug can be inserted into the opening of the paint can, thereby further sealing the opening of the paint can and preventing the paint from flowing out.

[0032] Furthermore, a limiting rod slidably connected to the pressure plate is provided at the top of the inner cavity of the outer cylinder.

[0033] It can be seen from the above description that the setting of the limiting rod can limit the upward and downward sliding of the pressing plate.

The incomplete active bevel gear 10 is located between the bevel gear assembly and the driven bevel gear 11, and is meshed with the bevel gear assembly and the driven bevel gear 11 in sequence. When the spraying tool is working, the pressure plate 4 is covered on the top of the coating tank 8, and the free end of the suction pipe 5 is inserted into a group of coating tanks 8.

[0036] Please refer to Figure 4 The bevel gear assembly includes a rotating disk 12 fixedly connected to the outer wall of the rotating rod 6, and a plurality of pawls 13 are fixedly connected to one side of the rotating disk 12 at equal angles. The outer wall of the rotating disk 12 is sleeved with an inner ratchet bevel gear 14 that cooperates with the pawls 13, and the inner ratchet bevel gear 14 is meshed and connected with the incomplete active bevel gear 10. The bottom of the inner ratchet bevel gear 14 is rotatably connected to the top of the external threaded sleeve 3 through a rotating bearing 15.

[0041] In this embodiment, the side wall of the outer cylinder 1 is provided with an openable discharge door to facilitate the replacement of the paint tank 8.

[0042] The working process of the above-mentioned spraying tool is as follows:

[0043] When it is necessary to spray paint on the display wall for display, the paints of various colors are poured into each paint can 8 in turn, and then the unloading door of the outer cylinder 1 is opened, and the paint can 8 is placed in each placement seat 72 in turn, and the rubber column 73 on the inner wall of the placement seat 72 can be squeezed and deformed, so that the paint can 8 is positioned under the action of the restoring force, and then the unloading door is closed.

[0045] After the straw 5 is inserted into the paint tank 8, the staff holds the spray head to spray the display wall.

[0046] After one paint spraying display is completed, the forward and reverse driving motor 9 is started in the forward direction (rotated one circle), and the driving motor drives the external threaded sleeve 3 to rotate forward, thereby driving the pressing plate 4 and the suction pipe 5 to slide upward, so that the straight tube 52 slides out of the paint tank 8, and then the incomplete active bevel gear 10 is meshed with the internal ratchet bevel gear 14 and drives the internal ratchet bevel gear 14 to rotate forward, thereby driving the rotating rod 6 and the rotating plate to rotate an angle, and the paint tank 8 of the next color is rotated to the bottom of the suction pipe 5, and finally the driving motor is started in the reverse direction to insert the suction pipe 5 into the paint tank 8 to complete the color switching of the paint tank 8, and the different colors of paint are sprayed and displayed in this way.

[0047] To sum up, the utility model provides a spraying tool for a building paint display wall. When spraying and displaying paint, paints of multiple colors can be loaded into paint cans and installed on the placement component respectively, and then the external threaded sleeve and the rotating rod are driven by the forward and reverse driving motors to rotate forward and reverse in turn, thereby realizing the up and down lifting of the suction tube and the switching of the position of the paint can respectively. In this way, different colors of paint can be sprayed and displayed in turn, and there is no need to frequently disassemble and replace the paint cans, thereby improving the display efficiency of the paint. In addition, the up and down lifting of the suction tube and the switching of the position of the paint can are controlled by the same set of driving motors, reducing the cost of the equipment.
