The adjusting sleeve 51 is used for lifting the splash-reducing sleeve 52, when the adjusting sleeve is implemented, gas in the telescopic sleeve 511 is directly led out through the stepped air guide channel 34, then the pressure in the telescopic sleeve 511 is reduced, the telescopic sleeve 511 is contracted and compresses the tightening groove 512, so that the length of the telescopic sleeve 511 can be fully adjusted, then the contracted telescopic sleeve 511 partially enters the hiding sleeve 513 to store the hidden contracted telescopic sleeve 511, and the air suction hole column 514 at the position limits the contracted telescopic sleeve 511 to prevent the contracted telescopic sleeve 511 from deviating.

As shown in fig. 1 and 2, a guide sleeve 516 is installed at one end of the pumping hole column 514, which is far away from the hidden sleeve 513, the guide sleeve 516 is sleeved outside the telescopic pipe sleeve 511, a sliding groove 517 is formed in the surface of the guide sleeve 516, a sputtering sleeve stop ring 518 is connected to the outer side wall of the guide sleeve 516 in a threaded manner, the sputtering sleeve stop ring 518 can slide along the outer side wall of the guide sleeve 516, an insertion reducing column 519 is arranged in the sliding groove 517, the end part of the insertion reducing column is connected with the inner wall of the sputtering sleeve stop ring 518 in a sliding manner, and the insertion reducing column 519 can be inserted into the tightening groove 512 and can slide along with the sputtering sleeve stop ring 518 along the sliding groove 517.

In this embodiment, the insertion reducing column 519 is slidably connected to the sputtering sleeve blocking ring 518, as shown in fig. 2, a groove is formed on the inner wall of the sputtering sleeve blocking ring 518, and the sputtering sleeve blocking ring 518 is threadedly connected to the guide sleeve 516, so that the position of the sputtering ring 52 can be accurately controlled.

In order to avoid the phenomenon that the splash-proof ring sleeve 52 is blocked and the like due to rapid movement of the telescopic pipe sleeve 511 when the telescopic pipe sleeve 511 contracts or extends, the movement of the telescopic pipe sleeve 511 is limited in speed, and then the position of the telescopic pipe sleeve 511 is determined so as to prevent the telescopic pipe sleeve 511 from continuing to move when the telescopic pipe sleeve 511 moves to a proper position.

Speed limiting action; when the telescopic tube housing 511 is moved, the insertion leg 519 inserted into the tightening slot 512 acts as a restriction so that when the tightening slot 512 is contracted up and down, the insertion leg 519 slides along the inner wall of the tightening slot 512 for the purpose of preliminary deceleration (the friction force is increased by further compressing the telescopic tube housing 511 when the insertion leg 519 is inserted), and the friction force of the insertion leg 519 is increased by the deceleration ring 515.

When the user needs to adjust the sliding height of the splash ring dropping sleeve 52, only the splash ring stopping ring 518 is rotated to slide along the guide sleeve 516, and the insertion reducing column 519 and the height limiting bar 5110 are lifted together, so that the moving amount of the telescopic tube sleeve 511 and the splash ring dropping sleeve 52 is increased.

As shown in fig. 2 and 5, a height limiting bar 5110 is installed at a side wall of the insertion reducing pole 519, and the height limiting bar 5110 can limit the extension length of the adjusting sleeve 51;

the thickness of the inserted reducing column 519 is not larger than the groove width of the tightening groove 512, so that the situation that the subsequent friction force is small due to the fact that the tightening groove 512 is flattened due to the fact that the thickness of the inserted reducing column 519 is too large is prevented, and a plurality of shaping strips 5111 are installed on the inner wall of the tightening groove 512, and the shaping strips 5111 are used for determining the shape of the tightening groove 512 to prevent the tightening groove 512 from being disappeared due to too much inflation.

And when the splash ring housing 52 slides up, the height can be restricted by the height restricting bar 5110.

As shown in fig. 2 and 4, the splash-reducing ring sleeve 52 comprises a splash-reducing sleeve 521 connected to one end of the telescopic pipe sleeve 511, which is far away from the pumping hole column 514, a sliding groove 522 is formed in a position, corresponding to the inclined plate 4232, of the inner side wall of the splash-reducing sleeve 521, one end of the splash-reducing sleeve 521, which is far away from the telescopic pipe sleeve 511, is connected with an edge drip-proof ring 523, and the edge drip-proof ring 523 can prevent paint attached to the inner wall of the splash-reducing sleeve 521 from dripping;

a plurality of raised grooves 524 are arranged in the edge anti-dripping ring 523, and the raised grooves 524 can guide the paint to be dispersed and gathered.

The specific structure of the splash-reducing ring sleeve 52 is not unique, but the splash-reducing ring sleeve 52 in the embodiment is used as a preferable scheme, the purpose of controlling the paint area can be achieved by shielding the paint range sprayed by the scattering head 421, the purpose of preventing the paint from being sprayed to the outer side of the area to be processed to cause the follow-up secondary cleaning of the spraying range (even if the object surface is polished without cleaning, the paint is affected), and the problem of low processing quality caused by the residual paint dropping on the processing surface can be prevented.

When the splashing ring sleeve 52 works specifically, sprayed paint can be shielded by the splashing sleeve 521, the shielded paint can gradually enter the edge anti-dripping ring 523 to be stored, the paint attached to the inner wall of the splashing sleeve 521 is prevented from dripping, and the convex groove 524 can guide the paint to be dispersed and gathered to prevent a large amount of paint from being gathered.

As shown in fig. 2, 3 and 4, the splash-reducing sleeve 521 includes a fixed ring sleeve 5211 connected to the telescopic pipe sleeve 511, one end of the fixed ring sleeve 5211 away from the telescopic pipe sleeve 511 is connected to an adjusting bag sleeve 5212, one end of the adjusting bag sleeve 5212 away from the fixed ring sleeve 5211 is connected to the edge drip-proof ring 523, and the adjusting bag sleeve 5212 can adjust the minimum coverage area of the paint cover ring;

the adjusting bag sleeve 5212 comprises a connecting bag sleeve 5213 connected between the edge anti-drip ring 523 and the fixed ring sleeve 5211, the connecting bag sleeve 5213 is communicated with the telescopic pipe sleeve 511, the inner wall of the connecting bag sleeve 5213 is connected with a plurality of expanding half rings 5214, the expanding half rings 5214 are distributed on the inner wall of the connecting bag sleeve 5213 according to an annular structure, the expanding half rings 5214 can introduce air into the connecting bag sleeve 5213 to expand the volume of the expanding half rings to form a circular sealing ring, one side of the expanding half ring 5214, which is close to the edge anti-drip ring 523, is connected with an inclined shielding piece 5215, and one end, away from the expanding half ring 5214, of the inclined shielding piece 5215 is connected with the edge of the edge anti-drip ring 523.

The specific structure of the splash reducing sleeve 521 is not exclusive, and the splash reducing sleeve 521 in the embodiment is a preferable scheme, and can further reduce the paint coverage area to match the area to be processed with a smaller area.

The fixed ring 5211 can slide directly along with the telescopic pipe casing 511 to cover a wide range of paint spraying range, and when a region to be processed with a smaller area is encountered, the gas in the telescopic pipe casing 511 can be guided into the expanding half rings 5214 (where the connecting bag casing 5213 mainly plays a role of connection), and then the expanding half rings 5214 expand their volume after the gas is introduced to form a circular sealing ring, as shown in fig. 3 and 4, at this time, the coverage area of the paint covering ring is at a minimum (refer to fig. 4 specifically), and the sprayed paint is guided into the edge anti-drip ring 523 through the inclined shielding plate 5215.
