[0002] In daily underground maintenance activities, adjustable wrenches are often used. Since the underground mining site is relatively humid, the ball valve heads on the underground pipelines are extremely prone to rust. On the market, ball valve heads are generally disassembled using wrenches, but it is often necessary to knock on the pipeline or the ball valve head to loosen it, and then disassemble it by turning the wrench. Over time, it is easy to cause the roller on the wrench to loosen and become unusable; on the market, there are also pipe pliers that clamp the ball valve head. When the pipe mouth of the pipe pliers clamps the ball valve head, the operator rotates the adjustment nut to change the clamping force of the pipe pliers, and then the pipe handle is rotated to achieve the purpose of disassembling or repairing the ball valve head. However, the force of manually rotating the nut is small, the clamping force on the pipe ball head is small, and it is inconvenient to use. Utility Model Content

[0019] The principles and features of the present invention are described below in conjunction with all the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0020] The utility model embodiment discloses a simple wrench.

[0021] Reference Figure 1-Figure 2A simple wrench includes a handle 1, a clamping head is provided at the end of the handle 1, the clamping head includes a first clamping part 2 and a nut 4, the nut 4 is welded to the end of the handle 1, the first clamping part 2 and the handle 1 are integrally formed, there is a distance between the first clamping part 2 and the nut 4, and an opening is provided so that the workpiece can be placed in the opening. The clamping head also includes an adjusting bolt 5 adapted to the nut 4, the adjusting bolt 5 moves toward / away from one end of the first clamping part 2, and the distance between the end of the first adjusting bolt 5 and the first clamping part 2 is changed by rotating the adjusting bolt 5 to adapt to workpieces of different diameters, and the roller-type design of adjusting the opening size in the prior art is cancelled, the structure is not easy to be damaged, and at the same time, the disadvantage of insufficient clamping force during pipe clamp-type clamping in the prior art will not occur.

[0022] The operator makes the first clamping part 2 come into contact with the ball valve thread head and rotates the adjusting bolt 5 so that the end of the adjusting bolt 5 is pressed against the outer wall of the ball valve thread head, so as to achieve the purpose of clamping the ball valve thread head through the first clamping part 2 and the adjusting bolt 5, and then the ball valve thread head can be removed from the pipeline by rotating the handle 1. When rotating the adjusting bolt 5, the operator can use a tool to rotate the adjusting bolt 5 to achieve the purpose of clamping the ball valve thread head, and the operation is convenient, which reduces the possibility that the ball valve thread head is not clamped tightly and the inconvenience of disassembling the ball valve thread head is reduced.

[0023] The end of the first adjusting bolt 5 is rotatably connected to the second clamping portion 3 that cooperates with the first clamping portion 2. Figure 2 As shown, since the first adjusting bolt 5 and the second clamping part 3 are rotatably arranged, the second clamping part 3 will not rotate when the first adjusting bolt 5 is rotated, so as to ensure that the second clamping part 3 can clamp the ball valve thread head normally. The second clamping part 3 fits the ball valve thread head to increase the contact area with the ball valve thread head, thereby further improving the clamping effect.

[0024] Reference Figure 2 The second clamping portion 3 has an arc-shaped surface close to the first clamping portion 2, which is adapted to the arc of the first clamping portion 2.
