[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0027] According to an embodiment of the present utility model, there is provided a Figures 1 to 6, comprising: a wrench handle 1; a wrench head 2, the wrench head 2 being fixed to the end of the wrench handle 1, one end of the wrench head 2 being connected with a first plate lip 21 and a second plate lip 22, the first plate lip 21 and the second plate lip 22 being arranged at intervals and forming a jaw 4 for clamping a workpiece with the wrench head 2; a pin lifting structure 3, the pin lifting structure 3 being connected to the end of the wrench handle 1 away from the wrench head 2, the pin lifting structure 3 comprising a first hook head 31 and a second hook head 32, the first hook head 31 and the second hook head 32 forming a hook groove 33; along the direction in which the wrench head 2 is away from the wrench handle 1, the cross-sectional area of ​​the first plate lip 21 gradually decreases, and along the direction in which the wrench head 2 is away from the wrench handle 1, the cross-sectional area of ​​the second plate lip 22 gradually decreases. When disassembling the hose joint 7 and the corresponding U-shaped pin 6 of the hydraulic pipeline, first use the first hook head 31 and the second hook head 32 of the pin lifting structure 3 to form a hook groove 33 to resist the arc surface at the upper end of the U-shaped pin 6, then hold the lever handle 1 to lift the pin upward, and after the U-shaped pin 6 is lifted to allow the first plate lip 21 or the second plate lip 22 to extend into the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, align the jaws 4 with the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, extend the first plate lip 21 or the second plate lip 22 into the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, then hold the lever handle 1 to lift the pin upward, and pull out the U-shaped pin 6. Moreover, for severely corroded hoses and U-shaped pins 6, after knocking the hose joint 7, the cross-sectional area of ​​the first plate lip 21 and the cross-sectional area of ​​the second plate lip 22 gradually decrease along the direction of the wrench head 2 away from the wrench handle 1, and the first plate lip 21 and the second plate lip 22 can be inserted into the hose joint 7 to disassemble the pipeline. The pin lifting structure 3 of the utility model can disassemble the hose joint 7 and the corresponding U-shaped pin 6 without affecting the original function of the wrench, achieving multi-purpose use and solving the technical problem of inconvenience for employees to carry tools and work; the structural characteristics of the first plate lip 21 and the second plate lip 22 facilitate the first plate lip 21 and the second plate lip 22 to extend into the hose joint 7, and severely corroded hoses and U-shaped pins 6 can also be disassembled, making the multifunctional wrench of this embodiment versatile and practical.

[0028] Specifically, see Figure 1 and Figure 5The first plate lip 21 of this embodiment is a movable plate lip, which is movably connected to the wrench head 2, and the movable plate lip, the second plate lip 22 and the wrench head 2 form an adjustable jaw 4. After the lifting pin structure 3 moves the U-shaped pin 6 to extend the movable plate lip into the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, the movable plate lip is adjusted to align the jaw 4 with the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, and the first plate lip 21 or the second plate lip 22 is extended into the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, and then the wrench handle 1 is held to lift the pin upward to pull out the U-shaped pin 6. The provision of the movable plate lip enables the multifunctional wrench of this embodiment to disassemble common hose joints 7 and corresponding U-shaped pins 6 from φ10 to φ25, thereby increasing the scope of application of the multifunctional wrench.

[0029] Specifically, see Figure 1 and Figure 4 The first plate lip 21 of this embodiment is a pyramid structure, and the first plate lip 21 includes a first clamping surface 211 in contact with the workpiece, a first connecting surface 212 and a second connecting surface connected to the first clamping surface 211, and a third connecting surface 213 located between the first connecting surface 212 and the second connecting surface, and a 30° angle is formed between the first connecting surface 212 and the second connecting surface. The setting of a 30° angle between the first connecting surface 212 and the second connecting surface is conducive to the first plate lip 21 of the pyramid structure extending into the gap between the arc surface at the upper end of the U-shaped pin 6 and the rubber hose for disassembly, and the first clamping surface 211 and the second plate lip 22 clamp the arc surface at the upper end of the U-shaped pin 6 to disassemble the U-shaped pin 6. The first plate lip 21 is set as a pyramid structure, so that the first plate lip 21 is easier to enter the gap between the arc surface at the upper end of the U-shaped pin 6 and the rubber hose, which is convenient for disassembly.

[0030] Specifically, see Figure 2 In this embodiment, at least one of the first connecting surface 212 and the second connecting surface is composed of a first inclined surface 2121 and a second inclined surface 2122. The second inclined surface 2122 is arranged close to the wrench head, and the angle between the first inclined surface 2121 and the second inclined surface 2122 is 120°-150°. Taking the first connecting surface 212 as an example, the angle between the first inclined surface 2121 and the second inclined surface 2122 is 120°-150°. The second inclined surface 2122 and the first inclined surface 2121 sequentially extend into the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose, so that the first plate lip 21 and the second plate lip 22 clamp the arc surface at the upper end of the U-shaped pin 6 to disassemble the U-shaped pin 6. The second connecting surface is the same as the first connecting surface 212. Moreover, this angle setting makes it easier for the first inclined surface 2121 and the second inclined surface 2122 to extend into the hose joint 7, so that the first plate lip 21 and the second plate lip 22 clamp the hose joint 7 to disassemble the pipeline. This arrangement enhances the practicability and functionality of the multifunctional wrench of this embodiment, and realizes multiple uses of one piece.

[0031] Specifically, the second plate lip 22 of the present embodiment is a fixed plate lip, the second plate lip 22 is fixedly connected to the wrench head 2, and the second plate lip 22 has the same structure as the first plate lip 21. With this arrangement, the second plate lip 22 and the first plate lip 21 can be more easily inserted into the gap between the arc surface at the upper end of the U-shaped pin 6 and the rubber hose and the rubber hose joint 7, and the U-shaped pin 6 and the pipeline can be disassembled. The worker only needs to carry the multifunctional wrench of the present embodiment to realize the disassembly of the rubber hose and the U-shaped pin 6.

[0032] Specifically, the second plate lip 22 of the present embodiment includes a second clamping surface 221 in contact with the workpiece, and the second clamping surface 221 is arranged opposite to the first clamping surface 211. In this arrangement, both the second clamping surface 221 and the first clamping surface 211 can clamp the U-shaped pin 6, and then both the second plate lip 22 and the first plate lip 21 can be more easily inserted into the gap between the arc surface at the upper end of the U-shaped pin 6 and the hose and the hose joint 7 for disassembly, making the multifunctional wrench of the present embodiment more flexible to use and more convenient for workers to operate.

[0033] Specifically, see Figure 1 and Figure 3 The lifting pin structure of this embodiment also includes an arc-shaped support point 34, and the arc-shaped support point 34 is arranged corresponding to the hook groove 33. The first hook head 31 and the second hook head 32 of the lifting pin structure 3 form a hook groove 33 to press against the arc surface of the upper end of the U-shaped pin 6, and the arc-shaped support point 34 presses against the hose joint 7. The U-shaped pin 6 is pried upward by holding the lever handle 1 to disassemble the U-shaped pin 6 of the hose joint 7. In this arrangement, the arc-shaped support point 34 presses against the pipeline by utilizing the principle of leverage, and the first hook head 31 and the second hook head 32 form a hook groove 33 to press against the arc surface of the upper end of the U-shaped pin 6 to pry the U-shaped pin 6 upward, which is very labor-saving for workers to operate and improves the disassembly efficiency.

[0034] Specifically, the hook groove 33 of this embodiment is a V-shaped hook groove, and the angle of the V-shaped hook groove is 120°. This arrangement enables the V-shaped hook groove to better resist the U-shaped pin 6 corresponding to the hose joint 7 of φ10 to φ25, making it easier to pry and also improving the disassembly effect.

[0035] Specifically, see Figure 1 The wrench handle of the present embodiment is provided with a hanging hole 5 for hanging the wrench, and the hanging hole 5 is a circular hanging hole. When the worker carries the wrench, the hanging hole can be hung around the waist or other places, making it more convenient to carry.

[0036] Specifically, see Figure 6For a longer or larger U-shaped pin, the first plate lip 21 can be adjusted so that the first plate lip 21 extends into the gap between the arc surface of the upper end of the U-shaped pin 6 and the hose, and the U-shaped pin enters the jaw 4. The first plate lip 21 is used to press against the arc surface of the upper end of the U-shaped pin 6 to pull out the U-shaped pin; or the first plate lip 21 and the second plate lip 22 are used to clamp the arc surface of the upper end of the U-shaped pin to pull out the U-shaped pin.

[0037] Many other changes and modifications can be made without departing from the concept and scope of the utility model. It should be understood that the utility model is not limited to a specific embodiment, and the scope of the utility model is defined by the appended claims.
