[0028] Embodiment 1:

[0029] like Figure 1-2As shown, this embodiment provides a wrench water pump pliers, including a fixed pliers body 11, a movable pliers body 21 and a movable handle 31; the movable pliers body 21 is sleeved on the outside of the fixed pliers body 11, the movable handle 31 is slidably connected to the fixed pliers body 11, and the movable handle 31 is used to control the movable pliers body 21 to slide on the fixed pliers body 11, and the fixed pliers body 11 and the movable pliers body 21 are respectively provided with a fixed pliers head 12 and a movable pliers head 22 of corresponding sizes and parallel to each other, so that the effective clamping areas of the fixed pliers head 12 and the movable pliers head 22 for the outer wall of the pipeline are of corresponding sizes, and the clamping effect on the pipeline is good.

[0030] like Figure 1-3 As shown, a rotating pin 34 is rotatably installed in the movable handle 31, and the rotating pin 34 is slidably connected to the ratchet groove 13 on the fixed pliers body 11. The rotating pin 34 is provided with a ratchet 341 that can be engaged with the ratchet groove 13; the torsion convex edge 33 on the movable handle 31 and the annular groove on the movable pliers body 21 are plugged and rotatably connected to each other.

[0031] When using the wrench water pump pliers of the present application: manually control the swing pin 34 to slide along its own axial direction, so that the ratchet 341 on the swing pin 34 is engaged or disengaged with the ratchet groove 13, so that the moving range of the movable pliers body 21 on the fixed pliers body 11 can be quickly adjusted according to the diameter of the pipeline, thereby increasing the convenience of product use.

[0032] Among them, since the movement control of the movable jaw body 21 on the fixed jaw body 11 is achieved by rotating the movable handle 31, the movable jaw body 21 has a compact structure and can be quickly disassembled and replaced after the movable jaw body 21 is worn out due to long-term use, thereby the product has high economic benefits.

[0033] Embodiment 2:

[0034] The features of this embodiment that are the same as those of the first embodiment are not described in detail. The difference between this embodiment and the first embodiment is that: Figure 1-5 As shown, in this embodiment, a button 35 is detachably fixedly mounted on the rotating pin 34, and the button 35 is slidably connected to the movable handle 31; the ends of the rotating pin 34 and the button 35 are respectively provided with a limit edge Ⅰ and a limit edge Ⅱ that can abut against the outer two side surfaces of the movable handle 31; pressing the button 35 allows the ratchet 341 and the ratchet groove 13 to quickly disengage from the engaged state, thereby adjusting the moving range of the movable pliers 21 on the fixed pliers 11.

[0035] In order to facilitate the quick reset of the rotation pin 34 on the movable handle 31, as shown in FIG. Figure 2 and Figure 5As shown, a spring sheet 32 ​​is fixedly installed on one side of the movable handle 31 so that the other end of the spring sheet 32 ​​overlaps with the end of the turn pin 34. By utilizing the elastic deformation characteristics of the spring sheet 32, the turn pin 34 always has a tendency to retract on the movable handle 31, maintaining a stable engagement state between the ratchet 341 and the ratchet groove 13, thereby increasing the stability of the product.

[0036] The spring sheet 32 ​​is detachably fixed on the movable handle 31 by means of screws 321 .

[0037] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the concept of the utility model.
