Oil core wrench structure improvement

The present invention relates to a structural improvement of a wick wrench, and more particularly to a structural improvement of a wick wrench that provides a one-way drive to provide fast drive and facilitate driving in a small space.

According to the general car maintenance, the disassembly and assembly of the oil core group is quite frequent and normal operation. However, the space of the oil core lock set on the engine is quite small, so the operation of the disassembly is quite equivalent. The inconvenience, and the general oil core wrench, as shown in the first to third figures, the oil core wrench 1 is mainly disposed on the abutting portion 11 and the screwing member 111 is pivoted on the top end of a screw 12, and An adjusting seat 13 is screwed on the screw 12 . The adjusting seat 13 is provided with a screw hole 131 on two sides thereof. The screw hole 131 is provided with a screwing element 132 penetrating through the through hole 141 of the two ends of the clamping element 14 . The screw is fixed on the screw hole 131, and the two ends of the clamping member 14 are fixed on two sides of the adjusting seat 13, and the end of the screw 12 is pivoted with a rotating handle 2, and is screwed by a screw The component 22 is inserted through the through hole of the rotating handle 2 and screwed to the end of the screw 12. Thus, by rotating the handle 2 to rotate the screw 12, the adjusting seat 13 can be displaced back and forth, and the clamping member 14 can be adjusted. The inner diameter is sized to disassemble and assemble the wick, however, the wick is assembled in the engine The space is rather narrow, which makes the slewing radius of the oil core wrench 1 relatively small in operation. When the oil core wrench 1 is driven by a finite distance and can no longer be rotated, the oil core wrench 1 needs to be rotated, but the slewing In order to prevent the oil core from rotating together, the oil core wrench 1 needs to first rotate the rotating handle 2, so that the screw 12 drives the displacement of the adjusting seat 13 so that the clamping member with the displacement thereof After the inner diameter and the oil core are separated from the clamping state, after rotating the rotating handle 2 and the abutting portion 11 to the original starting point of rotation, the rotating handle 2 is rotated, so that the inner diameter of the clamping member 14 and the oil core are again clamped. After that, the rotating handle 2 is driven again, and the operation is repeated until the purpose of disassembling and assembling the oil core is achieved, so that the working time for disassembling and assembling the oil core is increased.

Therefore, the inventor of this case is based on his years of experience in the design and manufacture of various hardware tools, especially the ink of the wrench tool. In view of the lack of effectiveness of the existing oil core wrench, it is possible to provide a one-way drive. It is conducive to the use in a small space, and it is actively researched and improved. Through many experiments and changes, the invention is finally produced.

The main object of the present invention is to provide a unidirectional control portion in the abutting portion of the wicking wrench, and the unidirectional control portion and the clamping member can achieve the rotation of the clamping oil core, and the oil core wrench can also be provided. When turning, the oil core will not follow the one-way transmission state of its rotation, in order to meet the requirements of quick disassembly and assembly of the oil core, and to provide the structure of the oil core wrench for driving in a small space.

For the purpose of the present invention, the present invention is mainly provided with a receiving groove at a position near the middle portion of the abutting portion of the oil core wrench, and a first abutting wall and a first side are respectively disposed on the two sides of the bottom end of the receiving groove.
