[0026] Embodiment 2: Refer to the attached Figure 6 and Figure 7 As shown, on the basis of Example 1, in order to realize the angle adjustment between the swing arm 4 and the traction arm 5, the base plate 1 is fixed with a limiting shaft 2 in the center of the top surface, the limiting shaft 2 is a "T"-shaped cylinder, and a sleeve 3 is sleeved on the rod body of the limiting shaft 2. The inner ring diameter of the sleeve 3 is smaller than the top surface diameter of the limiting shaft 2. A threaded hole 19 is provided on the surface of the swing arm 4, and a hand screw 20 is screwed inside the threaded hole 19. The bottom end of the hand screw 20 is inserted into the positioning hole 21. The positioning hole 21 is provided on the surface of the base plate 1. There are multiple positioning holes 21, and the multiple positioning holes 21 are distributed in a circle with the top surface center of the base plate 1 as a circle.

[0027] When adjusting the included angle between the swing arm 4 and the traction arm 5, loosen the hand-tightened screw 20. After the hand-tightened screw 20 is withdrawn from the positioning hole 21, there is no braking between the swing arm 4 and the base plate 1. Then,拨动 the swing arm 4 to drive the sleeve 3 to rotate around the limit shaft 2 as the central axis, and the adjustment of the included angle between the swing arm 4 and the traction arm 5 can be realized. After the angle adjustment is completed, turn the hand-tightened screw 20 back and insert it into the corresponding positioning hole 21 to brake the swing arm 4.

[0028] Example 3: Refer to the attached Figures 4 to 5 As shown, on the basis of Example 2, in order to clamp the wiring pipe between the pressing plate 11 and the backing plate 7, two baffles 10 are fixed on the top surface of the backing plate 7. The rubber plate 8 is located between the two baffles 10. A first limiting groove 9 is formed on the top surface of the rubber plate 8. The first limiting groove 9 is an arc-shaped groove. There are multiple first limiting grooves 9, and the multiple first limiting grooves 9 are arranged equidistantly and equally in size along the long side of the rubber plate 8; two rubber supporting blocks 14 are fixed on the top surface of the backing plate 7. The rubber plate 8 and the baffle 10 are both located between the two rubber supporting blocks 14; the pressing plate 11 is in a "C"-shaped plate structure. A second through hole 16 is formed on the top surface of the pressing plate 11. A first through hole 15 is formed on the surface of the rubber supporting block 14. The screw 17 passes through the first through hole 15 and the second through hole 16 and is fixed on the surface of the backing plate 7; after the nut 18 is screwed and locked on the rod body of the screw 17, the pressing plate 11 presses down the rubber supporting block 14 to generate elastic deformation; a second limiting groove 12 is formed on the bottom surface of the top plate of the pressing plate 11. The second limiting groove 12 is an arc-shaped groove. There are multiple second limiting grooves 12, and the second limiting grooves 12 correspond to the first limiting grooves 9 one by one. When the pressing plate 11 is located above the rubber plate 8, the first limiting groove 9 is directly above the corresponding rubber plate 8; a rubber sheet 13 is fixed on the surface of the second limiting groove 12. The rubber sheet 13 is an arc-shaped sheet.

[0029] Lap the water and electricity wiring pipes on the two backing plates 7 respectively, and then install the pressing plate 11 above the backing plate 7. After the screw 17 passes through the second through hole 16 on the surface of the pressing plate 11, lock the nut 18 on the screw 17. As the nut 18 is locked, the pressing plate 11 presses down the wiring pipe; then adjust the included angle between the swing arm 4 and the traction arm 5. As the swing arm 4 swings, the wiring pipe is bent and deformed. The random addition of the baffle 10 and the rubber sheet 13 is to provide a deformation space outside the wiring pipe when the swing arm 4 swings and prevent the wiring pipe from being broken.

[0030] Example 4: On the basis of Example 3, a method for using an auxiliary bending and guiding device for water and electricity installation is proposed, including the following steps:

[0031] Step 1: When adjusting the angle between the swing arm 4 and the traction arm 5, loosen the hand-tightened screw 20. After the hand-tightened screw 20 is withdrawn from the positioning hole 21, there is no braking between the swing arm 4 and the substrate 1. Then,拨动 the swing arm 4 to drive the sleeve 3 to rotate around the limit shaft 2 as the central axis, so as to adjust the angle between the swing arm 4 and the traction arm 5. After the angle adjustment is completed, turn the hand-tightened screw 20 back and insert it into the corresponding positioning hole 21 to brake the swing arm 4.

[0032] Step 2: Place the water and electricity wiring pipes on the two pads 7 respectively, and then install the pressing plate 11 above the pads 7. After the screw 17 passes through the second perforation 16 on the surface of the pressing plate 11, lock the nut 18 on the screw 17. As the nut 18 is tightened, the pressing plate 11 presses the wiring pipe downward. Then adjust the angle between the swing arm 4 and the traction arm 5. As the swing arm 4 swings, the wiring pipe is bent and deformed. The random addition of the baffle 10 and the rubber sheet 13 is to provide a deformation space outside the wiring pipe when the swing arm 4 swings, to prevent the wiring pipe from being broken.
