[0028] How this utility works:

[0029] Refer to the instruction manual Figure 1-4When in use, the staff first puts the shielding cover 7 on the top of the nozzle 6, and makes the two plug rods 8 and the adjacent plug holes on the same horizontal line. At this time, the two return springs 9 begin to contract inwards after the external force disappears, thereby driving the two handles 10 to move toward the adjacent side, so that the two handles 10 can easily drive the two plug rods 8 to close, so that the two plug rods 8 can be quickly plugged into the adjacent plug holes, so that the shielding cover 7 can be quickly fixed on the nozzle 6 for shielding and restriction, so that the handheld decorative ceiling spraying device, through the elastic reset function of the two return springs 9, the two return springs 9 can quickly pull the two plug rods 8 into the adjacent plug holes, so as to quickly fix the shielding cover 7 on the nozzle 6 for shielding work, so that the shielding cover 7 can block and limit the outside of the nozzle 6, avoiding paint splashing around during spraying and causing waste;

[0030] Refer to the instruction manual Figure 1-4 When the shielding cover 7 is fixed, the staff rotates the handle 36 in the forward direction, so that the handle 36 can drive the rotating rod 310 to rotate in the forward direction. When the rotating rod 310 rotates in the forward direction, it can drive the driving bevel gear 39 to rotate in the forward direction. When the driving bevel gear 39 rotates, it meshes with the driven bevel gear 37, thereby driving the driven bevel gear 37 to rotate in the forward direction, so that the driven bevel gear 37 can drive the threaded rod 31 to rotate in the forward direction through the rotating shaft 38. When the threaded rod 31 rotates in the forward direction, it can drive the driving plate 34 to slide upward on the two limiting rods 33, thereby limiting the position of the driving plate 34, so that the driving plate 34 can smoothly drive the two ejector rods 32 to be pushed out from the inner cavity of the connecting tube 2, so that the two ejector rods 32 can jointly drive the nozzle 6 to move upward, and the nozzle 6 can be moved upward. The length of the device can be quickly adjusted, so that the handheld decorative ceiling spraying device can quickly push the two top rods 32 out of the inner cavity of the connecting tube 2, so that the two top rods 32 can quickly drive the nozzle 6 to move upward, so as to conveniently adjust the distance between the nozzle 6 and the connecting tube 2, so as to achieve the effect of quickly adjusting the length of the device, so that the staff can use the device to quickly perform ceiling spraying work in indoor rooms with different working environments. When the length of the device is adjusted, the staff connects one end of the delivery pipe 4 to the delivery pump, and delivers it to the inner cavity of the nozzle 6 through the delivery pump and then sprays it out through the spray hole on the nozzle 6, so as to achieve the purpose of spraying the ceiling. The above is the entire working process of the utility model.
