Description

Technical Field

[0001] The utility model relates to the technical field of wrenches, in particular to a hammer wrench. Background Art

[0002] A wrench is a commonly used installation or disassembly tool that uses a lever to twist bolts, screws, nuts and other threaded fastening structures to open or hollow out the fixture. Wrenches are divided into fixed wrenches and adjustable wrenches, and are usually made of carbon structural steel or alloy structural steel.

[0003] There are many different types of wrenches, which can be used in different usage environments to meet the installation or disassembly of different structures. However, there is currently no suitable wrench for installing or disassembling the bolts or nuts at the bottom of the barrel. Usually, the operator extends his arm completely into the barrel, and matches the wrench with the bolts or nuts based on experience and force conditions, and then performs installation or disassembly. This is not only inconvenient to operate, but also the operator is restricted by the barrel, etc., and it is difficult to find a suitable leverage point, that is, the force applied to the wrench is relatively small. Utility Model Content

[0004] In order to solve the above problem, that is, there is currently a lack of a wrench suitable for installing or removing barrel bottom bolts or nuts, the utility model proposes a hammer wrench, which includes a ladder frame, the short plate of the ladder frame is provided with a hexagonal hole, the ladder frame is rotatably connected to a rotating column, the rotating column is fixedly connected to two hammer heads through a connecting plate, the two hammer heads are symmetrically arranged about the rotating column, and the ladder frame is provided with a hammer plate corresponding to the two hammer heads.

[0005] The utility model is further configured as follows: a rectangular mounting hole is provided on the short plate of the ladder frame, a rectangular block is embedded in the mounting hole, and the hexagonal hole is provided on the rectangular block.

[0006] The utility model is further configured as follows: a U-shaped frame is further provided on the short plate of the ladder frame, and the two ends of the U-shaped frame are used to press the rectangular block; the rotating column passes through the long plate of the ladder frame and is rotatably connected to the U-shaped frame.

[0007] The utility model is further configured as follows: a handle perpendicular to the rotating column is provided at the top end of the rotating column.

[0008] The beneficial effects of the utility model are:

[0009] By rotating the rotating column, the two hammer heads can be driven to rotate, thereby achieving hammering of the two hammer plates, thereby driving the ladder frame to rotate, and the hexagonal holes on the ladder frame can be engaged with the nuts or caps of the bolts, and then the ladder frame drives the bolts or nuts to rotate through the hexagonal holes, thereby achieving the installation or removal function of the bolts or nuts. When using this device to install or remove the bolts or nuts at the bottom of the barrel, the operator only needs to turn the handle to achieve it, and there is no need to extend the arm into the barrel to operate. Further, the operation is simpler and more convenient, will not be restricted by the barrel, and is more suitable for the installation or removal of the bolts or nuts at the bottom of the barrel.

[0015] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0016] The utility model proposes a hammer wrench, including a ladder frame 1, the ladder frame 1 is arranged in an isosceles trapezoid, the long plate of the ladder frame 1 is arranged above the short plate, the short plate of the ladder frame 1 is provided with a hexagonal hole 111, the hexagonal hole 111 is adapted to the nut of the bolt, the long plate of the ladder frame 1 is rotatably connected with a rotating column 2, the rotating column 2 is arranged vertically, two connecting plates 21 are welded on the rotating column 2, the connecting plates 21 are arranged perpendicular to the rotating column 2, the two connecting plates 21 are symmetrically arranged about the rotating column 2, and a hammer head 211 is welded at one end of the connecting plate 21 away from the rotating column 2. Hammer plates 12 are integrally arranged at both ends of the long plate of the ladder frame 1, and the two hammer plates 12 are arranged corresponding to the two hammer heads 211, that is, when the rotating column 2 is rotated, the two hammer heads 211 can be driven to hammer the two hammer plates 12.

[0017] A rectangular mounting hole 13 is provided in the middle of the short plate of the ladder frame 1, and both ends of the mounting hole 13 are open. A rectangular block 11 is embedded in the mounting hole 13, and a hexagonal hole 111 is provided on the rectangular block 11, so that different rectangular blocks 11 can be replaced in the mounting hole 13, that is, hexagonal holes 111 of different sizes are provided on different rectangular blocks 11, so that the adaptability of the device can be stronger and the function of installing or removing bolts or nuts of different sizes can be met.

[0018] A U-shaped frame 14 is also welded to the upper surface of the short plate of the ladder frame 1. The U-shaped frame 14 is inverted, and one of the two ends of the U-shaped frame 14 is inserted into the mounting hole 13, so that the rectangular block 11 can be pressed tightly. Figure 2 shown.

[0019] The bottom end of the rotating column 2 passes through the long plate of the ladder frame 1 and is rotatably connected to the U-shaped frame 14, thereby enabling the rotation of the rotating column 2 to be more stable.

[0020] A handle 22 is welded to the top of the rotating column 2 , and the handle 22 is arranged perpendicular to the rotating column 2 . The handle 22 can be used to more conveniently rotate the column.

[0021] In summary, the utility model can drive the two hammer heads 211 to rotate by rotating the rotating column 2, thereby achieving the hammering of the two hammer plates 12, thereby driving the ladder frame 1 to rotate, and the hexagonal hole 111 on the ladder frame 1 can be buckled with the nut or nut of the bolt, and then the ladder frame 1 drives the bolt or nut to rotate through the hexagonal hole 111 to achieve the installation or removal function of the bolt or nut. When the device is used to install or remove the bolt or nut at the bottom of the barrel, the operator only needs to rotate the handle 22 to achieve it, and there is no need to extend the arm into the barrel to operate. Further, the operation is simpler and more convenient, and it will not be restricted by the barrel, which is more suitable for the installation or removal of the bolt or nut at the bottom of the barrel. At the same time, by replacing the rectangular block 11, the purpose of installing or removing bolts or nuts of different sizes can also be achieved, making the adaptability of the device stronger. .
