DETAILED DESCRIPTION
[0015] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further explained in detail below by specific embodiments combined with the drawings. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.
[0016] In one embodiment, as shown in the accompanying drawings Figs. 1-3As shown, the pipe bending tool comprises: a streamlined pincer-shaped main handle 1 with a wide upper part and a narrow lower part and a hollow interior, a streamlined pincer-shaped auxiliary handle 2 with a width that is the same from top to bottom, a rivet rotating shaft 3, a trapezoidal top rear vertical plate 5, and a horizontal blocking rod 6. The lower end of the streamlined pincer-shaped main handle 1 and the streamlined pincer-shaped auxiliary handle 2 is suitable for being held tightly by a single hand. The upper end of the streamlined pincer-shaped auxiliary handle 2 is a rectangular vertical support plate 7. The streamlined pincer-shaped main handle 1 and the streamlined pincer-shaped auxiliary handle 2 are arranged in a cross shape and are movably connected at the intersection point via the rivet rotating shaft 3. A through slot is formed in the side of the streamlined pincer-shaped main handle 1 close to the streamlined pincer-shaped auxiliary handle 2 and the top. The upper half of the streamlined pincer-shaped auxiliary handle 2 passes through the through slot of the streamlined pincer-shaped main handle 1. The top of the streamlined pincer-shaped main handle 1 is a main handle rectangular slotted top 4. A circular arc-shaped top plate 8 with a central angle of 180° is fixedly connected to the upper end of the vertical support plate 7. The long side of the top rear vertical plate 5 is fixed to the top of the streamlined pincer-shaped main handle 1. The top rear vertical plate 5 is arranged at the rear side of the through slot opening of the top. Two cylindrical horizontal blocking rods 6 are symmetrically welded to the upper end of the top rear vertical plate 5. The horizontal blocking rods 6 pass over the through slot or the extension line of the through slot. When the lower half of the streamlined pincer-shaped main handle 1 and the streamlined pincer-shaped auxiliary handle 2 are closest, the height of the arc-shaped top plate 8 is higher than that of the horizontal blocking rod 6. When the lower half of the streamlined pincer-shaped main handle 1 and the streamlined pincer-shaped auxiliary handle 2 are farthest, the height of the arc-shaped top plate 8 is lower than that of the horizontal blocking rod 6. The vertical distance is 6-32 mm. Part of the arc-shaped top plate 8 is arranged in the through slot.
[0017] Method of use: The part to be bent of the pipe 9 is horizontally placed on the top of the arc-shaped top plate 8 and the two ends are placed below the two horizontal blocking rods 6. The operator holds the streamlined pincer-shaped main handle 1 with the palm and presses the streamlined pincer-shaped auxiliary handle 2 with the fingers (the streamlined pincer-shaped auxiliary handle 2 is rotated via the rivet rotating shaft 3). The upper part of the streamlined pincer-shaped auxiliary handle 2 can pass through the slot hole of the main handle rectangular slotted top 4 and lift the arc-shaped top plate 8 connected to the vertical support plate 7 upward. The part to be bent of the pipe 9 placed on the arc-shaped top plate 8 is lifted upward to the left. The two horizontal blocking rods 6 at the two ends of the side of the top rear vertical plate 5 block and fix the two sides of the pipe 9 to be bent. When the required arc degree is reached, the operator relaxes the fingers, extracts the pipe 9 to be bent and uses it for construction. The arc-shaped top plate 8 is retracted downward with the rectangular vertical support plate 7 in the main handle top and is relaxed and reset.
