Because the two normally open contact ends of the relay J are respectively connected with the pins 1 and 2 at the two ends of the power input of the first set of time control switch A2, therefore, at the moment, the time control switch A2 is in an electrified working state, and the 3 and 4 pins of the time control switch A2 output positive and negative pole power supplies for a certain time (for example, 3 seconds) to enter the positive and negative pole power supply input ends of the two sets of electric telescopic rods M1 and M2 under the action of an internal circuit and the output power supply time set by a technician, so that the two sets of electric telescopic rods M1 and M2 are electrified to work, under the action of mechanisms such as internal motors of the two sets of electric telescopic rods M1 and M2, the plunger rod can synchronously drive the nozzle 2 and the connecting pipe 1 to move upwards for a certain distance (stop after 3 seconds), so that the distance between the lower ends of the connecting pipe 1 and the nozzle 2 and the upper end of the middle part of the automobile body is enlarged, and the phenomenon that the spraying effect of the middle part of the automobile body is poor due to the fact that the distance between the nozzle 2 and the middle part of the automobile body is too small is avoided. In this is novel, in the backward movement has been accomplished in the spraying of automobile body front end, because support column 10 leans on preceding 0.5cm more than connecting pipe 1 about, consequently in fact before 2 spraying automobile body middle parts upper ends of nozzle, two sets of electric telescopic handle M1 and M2 are driving nozzle 2 and connecting pipe 1 rise height, when just the nozzle is located automobile body middle part upper end front portion, three nozzle 2's height just adjusts and targets in place, has satisfied the needs of three nozzle 3 to automobile body middle part upper end spraying height.

Fig. 1, 2 in show, in this is novel, the spraying finishes in the middle part of the automobile body, the automobile body is carried towards the back by conveyer belt production facility in, conveyer belt production facility will need the automobile body rear end of spraying paint to carry behind nozzle 2, the automobile body rear end is owing to can not block the infrared light that photoelectric switch a1 detecting head launches, photoelectric switch a1 is under its internal circuit effect so, its 3 feet can not export the base that the high level got into NPN triode Q, then, NPN triode Q ends its collecting electrode can not export the low level and gets into relay J negative pole power input end, relay J is in its two control power ends of power failure state and two normally closed contact ends are closed respectively. Because the two normally closed contact ends of the relay J are respectively connected with the two ends 1 and 2 of the power input of the second set of time control switch A3, therefore, at the moment, the time control switch A3 is in an electrified working state, the

pins

3 and 4 of the time control switch A3 can output negative and positive power supplies for a certain time (for example, 3 seconds) to enter the negative and positive power supply input ends of the two sets of electric telescopic rods M1 and M2 under the action of an internal circuit and the output power supply time set by a technician, so that the electric telescopic rods M1 and M2 are electrified to work, under the action of mechanisms such as internal motors of the two sets of electric telescopic rods M1 and M2, the plunger rod can synchronously drive the nozzle and the connecting pipe 1 to move downwards for a certain distance (stop after 3 seconds), so that the distance between the lower ends of the connecting pipe 1 and the nozzle 2 and the upper part of the rear end of the vehicle body is reduced, and poor spraying effect of the rear part of the vehicle body caused by overlarge distance between the nozzle 2 and the rear part of the vehicle body is prevented. In this novel, when the automobile body middle part spraying has been accomplished the backward movement, because support column 10 is more than connecting pipe 1 and leans on preceding 0.5cm left and right sides, consequently in fact nozzle 2 spraying automobile body rear portion upper end before, two sets of electric telescopic handle M1 and M2 have been driving nozzle 2 and connecting pipe 1 descending height, when just the nozzle is located automobile body rear portion upper end front portion, three nozzle 2's height just adjusts and targets in place, has satisfied three nozzle 3 and has reached the high needs of automobile body rear portion upper end spraying.
