When the clamping block 210 is attached to the surface of the hot air gun through the second clamping block 212, it will rotate accordingly in the inner wall of one end of the push rod 27 according to the outer surface shape of the hot air gun. At the same time, several second clamping blocks 212 will rotate in different directions with the help of the universal joint 211 according to the outer surface shape of the hot air gun, so as to fit better with the surface of the hot air gun. Then the suction cup 213 on the second clamping block 212 will be adsorbed on the outer surface of the hot air gun to fix it for a second time, so that its limit can be more firmly and stably limited. By adjusting the first clamping block 210, hot air guns of different sizes can be clamped and limited, and then the universal joint 211 and several second clamping blocks 212 can be precisely fitted and limited for hot air guns with different shapes. Finally, the suction cup 213 is used to adsorb and fix its surface for a second time, so as to achieve support and fixation of hot air guns of different power, model size and appearance, improve the fixing support effect and use adaptability of the limit frame 5 and the support frame 4, and facilitate use.
[0031] After the adjusting limit device 2 is used to clamp and fix the hot air gun, the base 1 is placed on one side of the workpiece that needs to be heated. Finally, according to the position and height of the workpiece that needs to be heated, one end of the plug block 35 is manually held and then pulled outward in the clamping hole 33, driving the second spring 36 to be stretched and one end is pulled out of the clamping groove 34.
