[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the described embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1: Please refer to Figures 1 to 6 :

[0030] The utility model proposes a three-hole fender bracket special spray painting hanger, comprising: a main hanger 1, an outer hook 2 and a middle slide rod 3, an upper connecting hanger plate 101 is fixed on the upper part of the main hanger 1, three outer connecting frames 102 are fixed on the annular array of the main hanger 1, one of the three outer connecting frames 102 is screwed with an outer screw 103, and the other two of the three outer connecting frames 102 are penetrated and slid with outer slide rods 105, the lower end of the outer screw 103 is rotatably connected with a lower limit ring 104, the lower end of the outer slide rod 105 is fixedly connected with the lower limit ring 104, the lower end of the outer connecting frame 102 is rotatably connected with the upper end of the outer hook 2, the outer screw 103 moves axially along the thread, the outer screw 103 and the lower limit ring 104 move synchronously to adjust the position, and the lower limit ring 104 limits the upward movement of the lower connecting slide frame 301 The moving distance is that an outer hook 2 is arranged on the outer side of the main hanger 1, and a tail hook 201 is opened at the tail end of the outer hook 2. The outer hook 2 is an L-shaped structure, and the tail hook 201 of the outer hook 2 hooks the three holes of the three-hole fender bracket workpiece from the three-hole position. A middle slide bar 3 is axially slidable in the center axis of the main hanger 1, and a lower connecting slide slot frame 301 is fixed to the lower annular array of the middle slide bar 3. An upper nut 302 is screwed on the upper end of the middle slide bar 3, and the bottom of the upper nut 302 and the top of the upper support spring 303 are slidably fitted, and the lower end of the upper support spring 303 and the top of the main hanger 1 are slidably fitted, and the upper support spring 303 supports the middle slide bar 3 to move upward, and the lower limit ring 104 is above the lower connecting slide slot frame 301, and the upper nut 302 compresses the length of the upper support spring 303 to increase the supporting force of the upper support spring 303, and adjusts the supporting force of the upper support spring 303 on the middle slide bar 3.

[0031] In the embodiments of the present disclosure, as shown in the attached Figure 1 , 2 As shown in Figure 3, the front end of the external hook 2 is slidably connected to the slide groove of the lower connecting slide groove frame 301, the lower connecting slide groove frame 301 pulls the front end of the external hook 2 to move upward, the external hook 2 rotates around the rotating connection with the external connecting frame 102, and one end of the tail hook 201 of the external hook 2 tilts toward the side of the main hanger 1, thereby increasing the clamping force of the tail hook 201 on the three-hole fender bracket workpiece.

[0032] In the embodiments of the present disclosure, as shown in the attached Figure 1 , 2 As shown in , 3, 4, and 5, the upper support spring 303 supports the upper nut 302 and the middle slide rod 3 to move upward, and the tail hook 201 tilts toward the side of the main hanger 1. The tail hook 201 further increases the clamping force on the three-hole fender bracket workpiece, and the installation is more secure. The top of the lower connecting slide frame 301 and the bottom of the lower limit ring 104 fit together, and the lower limit ring 104 limits the moving distance of the lower connecting slide frame 301, thereby limiting the range of the lower connecting slide frame 301 to guide the outer hook 2 to rotate.

[0033] Embodiment 2, on the basis of embodiment 1, the outer hook 2 is arranged in three circular arrays, the upper end of the outer hook 2 and the lower end of the upper connecting plate 101 are welded and fixed, and the tail hook 201 of the outer hook 2 hooks the three holes of the three-hole mudguard bracket workpiece from the three-hole position to achieve the purpose of hanging, further simplifying the number of structures of the hanger and reducing the cost of the hanger. However, because the outer hook 2 is fixed, it is easy to be deformed and bent when the outer hook 2 is pulled when separated from the workpiece, and embodiment 1 can avoid this situation.

[0034] The working principle of this embodiment is as follows: the upper connecting hanging plate 101 is connected to the conveyor belt, and the upper connecting hanging plate 101 moves with the conveyor belt for electrophoresis, the outer hook 2 surrounds the outer side of the three-hole mudguard, and the tail hook 201 of the outer hook 2 hooks the three holes of the three-hole mudguard bracket workpiece from the three-hole position of the three-hole mudguard bracket workpiece. The distance between the outer hooks 2 is large and the contact surface with the three-hole mudguard bracket workpiece is smaller, ensuring that the three-hole mudguard bracket workpiece is processed and cleaned before painting, and the cleaning liquid flows out smoothly without accumulating liquid. The large spacing of the outer hooks 2 ensures that the coating surface is fully exposed, avoiding the influence of the hanging point on the paint surface, and the operation is simple, and the installation is reliable and efficient.

[0035] The upper supporting spring 303 supports the middle slide bar 3 to move upward, and the middle slide bar 3 and the lower connecting slide slot frame 301 move upward synchronously, and the lower connecting slide slot frame 301 pulls the head end of the outer hook 2 to move upward, and the outer hook 2 rotates around the rotating connection of the outer connecting frame 102, and one end of the tail hook 201 of the outer hook 2 tilts toward the side of the main hanger 1, and the tail hook 201 further increases the clamping force on the three-hole mudguard bracket workpiece, and the installation is more secure. At the same time, when the workpiece is disassembled, one outer hook 2 is moved, and the outer hook 2 pulls the lower connecting slide slot frame 301 and the middle slide bar 3 to move downward, and the lower connecting slide slot frame 301 slides the other two outer hooks 2 to move synchronously, and the three outer hooks 2 move synchronously to expand outward and separate from the three-hole mudguard to avoid the situation where one three-hole mudguard is not separated from the three-hole mudguard, causing the outer hook 2 to be pulled and deformed;

[0036] After the upper and lower limit switches 303 are pressed together, the upper and lower limit switches 303 are pressed together, and the upper and lower limit switches 303 are pressed together to form a pressure relief valve 306.
