[0019] In actual use, after the spray gun is used, the protective end cover 2 is installed on the surface of the nozzle 1, and the groups of plugs 4 arranged on the surface of the plug mounting plate 5 are inserted into the groups of paint spray holes 3 opened on the surface of the nozzle 1. The plugs 4 push the residual paint in the paint spray holes 3 out of the paint spray holes 3, thereby preventing the paint from drying in the paint spray holes 3 and causing the paint spray holes 3 to be blocked.

[0020] Embodiment 2

[0021] On the basis of embodiment one, in order to facilitate the alignment of each group of plugs 4 with each group of paint spray holes 3, a spring 7 is sleeved on the rod body of the push rod 6, one end of the spring 7 rests on the surface of the plug mounting plate 5, and the other end of the spring 7 rests on the inner wall of the protective end cover 2.

[0022] When the protective end cover 2 is not installed on the surface of the nozzle 1, the spring 7 pushes the plug mounting plate 5 to the opening of the protective end cover 2, so that each group of plugs 4 is exposed from the opening of the protective end cover 2, making it easy to observe the relative position of the plugs 4 and the paint holes 3, thereby facilitating the alignment of each group of plugs 4 with each group of paint holes 3.

[0023] Embodiment 3

[0024] On the basis of Example 2, in order to realize the disassembly and assembly of the protective end cover 2 and the nozzle 1, a protective end cover 2 is provided on the surface of the nozzle 1 through a threaded connection, and a push rod hole 8 is opened at the end of the protective end cover 2. The push rod hole 8 has a circular hole structure, and a push rod 6 is movably inserted in the push rod hole 8. The push rod 6 has a round rod structure, one end of the push rod 6 is fixed on the end surface of the plug mounting plate 5 away from the plug 4, and a stop plate 9 is fixed to the other end of the push rod 6. A spring 7 is sleeved on the rod body of the push rod 6, one end of the spring 7 rests on the surface of the plug mounting plate 5, and the other end of the spring 7 rests on the inner wall of the protective end cover 2, and the stop plate 9 has a circular plate structure, and the diameter of the stop plate 9 is larger than the aperture of the push rod hole 8.

[0025] When installing the protective end cover 2, first insert each group of plugs 4 into each group of paint spray holes 3, then push the protective end cover 2 in the direction close to the nozzle 1, so that the thread of the protective end cover 2 is engaged with the thread of the nozzle 1, and then screw the protective end cover 2 so that the protective end cover 2 is gradually installed on the surface of the nozzle 1 through the threaded connection. When the protective end cover 2 is screwed, the paint spray holes 3 are inserted in the plugs 4 and cannot rotate with the protective end cover 2. Therefore, in order to meet the connection between the plugs 4 and the protective end cover 2 while preventing the plugs 4 from hindering the rotation of the protective end cover 2, each group of plugs 4 is set on a group of plug mounting plates 5, and a push rod 6 is fixed to the other end of the plug mounting plate 5. The push rod 6 is movably inserted in the push rod hole 8 opened on the surface of the protective end cover 2. When the protective end cover 2 rotates, the push rod 6 is inserted in the push rod hole 8 on the one hand. It rotates relative to the protective end cover 2, and on the other hand, remains stationary relative to the plug mounting plate 5, thereby achieving the connection between each group of plugs 4 and the protective end cover 2 while preventing the plugs 4 from interfering with the rotation of the protective end cover 2, so that the protective end cover 2 can be installed on the surface of the nozzle 1 through a threaded connection; when removing the protective end cover 2, the protective end cover 2 is screwed in the reverse direction to make the thread of the protective end cover 2 gradually withdraw from the spiral thread on the surface of the nozzle 1, and the spring 7 gradually pushes the plug mounting plate 5 to the opening of the protective end cover 2 again under the elastic action. At the same time, a stop plate 9 is fixed to the end of the push rod 6 away from the plug mounting plate 5. The diameter of the stop plate 9 is larger than the aperture of the push rod hole 8, which can prevent the push rod 6 from withdrawing from the push rod hole 8, and also prevent the plug mounting plate 5 from being ejected from the protective end cover 2 by the spring 7.

[0028] A first rope ring 10 is arranged on the surface of the stop plate 9, a second rope ring 11 is arranged on the surface of the nozzle 1, and a pull rope 12 connects the first rope ring 10 and the second rope ring 11 together, so that the protective end cover 2 will not be lost when it is removed.

[0029] In actual use, after the spray gun is used, the protective end cover 2 is installed on the surface of the nozzle 1, and the groups of plugs 4 arranged on the surface of the plug mounting plate 5 are inserted into the groups of paint spray holes 3 opened on the surface of the nozzle 1. The plugs 4 push the paint remaining in the paint spray holes 3 out of the paint spray holes 3, thereby preventing the paint from drying in the paint spray holes 3 and causing the paint spray holes 3 to be blocked; when the protective end cover 2 is not installed on the surface of the nozzle 1, the spring 7 pushes the plug mounting plate 5 to the opening of the protective end cover 2, so that the groups of plugs 4 are exposed from the opening of the protective end cover 2, which is convenient for observing the relative positions of the plugs 4 and the paint spray holes 3. When the protective end cap 2 is installed, each group of plugs 4 is first inserted into each group of paint spraying holes 3, and then the protective end cap 2 is pushed in the direction close to the nozzle 1, so that the thread of the protective end cap 2 is engaged with the thread of the nozzle 1, and then the protective end cap 2 is screwed, so that the protective end cap 2 is gradually installed on the surface of the nozzle 1 through the threaded connection. When the protective end cap 2 is screwed, the paint spraying holes 3 are inserted in the plugs 4 and cannot rotate with the protective end cap 2. Therefore, in order to meet the connection between the plugs 4 and the protective end caps 2 while preventing the plugs 4 from hindering the rotation of the protective end cap 2, each group of plugs 4 is set in a On the plug mounting plate 5 of each group, a push rod 6 is fixed at the other end of the plug mounting plate 5, and the push rod 6 is movably inserted in the push rod hole 8 opened on the surface of the protective end cover 2. When the protective end cover 2 rotates, the push rod 6 rotates in the push rod hole 8 relative to the protective end cover 2 on the one hand, and remains stationary relative to the plug mounting plate 5 on the other hand, so that each group of plugs 4 and the protective end cover 2 are connected while the plugs 4 do not hinder the rotation of the protective end cover 2, so that the protective end cover 2 can be installed on the surface of the nozzle 1 through a threaded connection; when the protective end cover 2 is removed, the protective end cover 2 is screwed in the reverse direction so that the thread of the protective end cover 2 gradually moves away from the nozzle 1. The plug 6 withdraws from the spiral on the surface of the nozzle 1, and the spring 7 gradually pushes the plug mounting plate 5 to the opening of the protective end cover 2 again under the elastic action. At the same time, a stop plate 9 is fixed to the end of the push rod 6 away from the plug mounting plate 5. The diameter of the stop plate 9 is larger than the aperture of the push rod hole 8, which can prevent the push rod 6 from withdrawing from the push rod hole 8, and also prevent the plug mounting plate 5 from being ejected from the protective end cover 2 by the spring 7; a first rope ring 10 is arranged on the surface of the stop plate 9, and a second rope ring 11 is arranged on the surface of the nozzle 1. The pull rope 12 connects the first rope ring 10 and the second rope ring 11 together, so that the protective end cover 2 will not be lost when it is removed.
