Description

Oil core wrench structure improvement

This creation relates to a structural improvement of a wick wrench, especially one that provides a one-way drive to provide quick drive and improved oil core wrench structure for driving in tight spaces.

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 needs to be turned first. Rotating the rotating handle 2 causes the screw 12 to drive the displacement of the adjusting seat 13 so that after the inner diameter of the clamping member 14 displaced therefrom 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, After rotating the rotating handle 2, the inner diameter of the clamping member 14 and the oil core are again clamped, and then the rotating handle 2 is driven, and the operation is repeated, so as to achieve the purpose of disassembling and assembling the oil core, thereby increasing the disassembly. Working time with assembled oil cores.
