Description

Spanner for disassembling and assembling engine oil filter Technical Field The utility model relates to the technical field of filter disassembly and assembly, in particular to an oil filter disassembly and assembly wrench. Background When the vehicle is maintained, the oil filter is required to be replaced, and the oil filter is difficult to disassemble or assemble in place by manual operation alone, so that a special disassembly wrench for the oil filter is required to be utilized. The engine oil filter spanner is a special tool commonly used in automobile maintenance, is mainly used for disassembling and installing the engine oil filter, and is mainly divided into the following types: 1. The wrench of the copied oil filter is directly sleeved on the polygonal surface of the top of the oil filter, and is suitable for a standard-size filter. However, each wrench can only correspond to a single size and needs to be used in a complete set. 2. The three-jaw type engine oil filter wrench is internally provided with a planetary gear mechanism, so that the size of the three jaws can be automatically adjusted, the three-jaw type engine oil filter wrench is suitable for filters with various sizes, and the trouble of manual adjustment is reduced. But the structure is complex and the maintenance cost is high. 3. The chain/belt type oil filter spanner adopts a chain or belt structure, is operated by a lever principle, is suitable for disassembling a filter with a larger size, has poor universality and is easy to release. 4. The open box spanner/ratchet spanner is suitable for disassembling and assembling the bolt of the filter seat, can be quickly unscrewed or locked, but cannot directly treat the filter body. In combination with the above, the wrenches for disassembling and assembling the oil filter body are commonly used only in three types, and each of the wrenches has certain drawbacks, namely, the existing oil filter wrenches have poor suitability. Disclosure of utility model In order to solve the problem that the suitability of an existing oil filter wrench is poor, the utility model provides an oil filter disassembly wrench which comprises a handle, wherein one end of the handle is rotationally connected with an arc-shaped long chain I, one end of the arc-shaped long chain I, which is away from the handle, is rotationally connected with an arc-shaped long chain III, one end of the arc-shaped long chain II, which is away from the arc-shaped long chain I, is rotationally connected with an arc-shaped long chain III, one end of the arc-shaped long chain III, which is away from the arc-shaped long chain II, is hinged with a chain, a sliding cylinder is slidably connected with the handle, an opening is formed in the side wall of the handle, one end, which is away from the arc-shaped long chain III, penetrates through the opening and is connected with the sliding cylinder, and a locking mechanism is arranged on the sliding cylinder. The locking mechanism comprises a clamping column perpendicular to the handle, a row of clamping holes and a sliding groove are formed in the side wall of the handle, and two ends of the clamping column are respectively arranged in the clamping holes and the sliding groove. The utility model is further characterized in that a spring is sleeved on the clamping column, a stop lever is fixedly connected to the clamping column, the stop lever is perpendicular to the clamping column, the spring and the stop lever are both arranged in the sliding cylinder, and two ends of the spring are respectively propped against the clamping column and the inner wall of the sliding cylinder. The novel anti-skid chain is further characterized in that the structures of the arc-shaped long chain I, the arc-shaped long chain II and the arc-shaped long chain III are the same, and anti-skid teeth are formed on the inner cambered surface of the arc-shaped long chain I. The utility model is further arranged that the arc-shaped long chain I comprises three arc plates which are sequentially arranged from top to bottom, wherein the upper arc plate and the lower arc plate are correspondingly arranged, the middle arc plate is arranged in a staggered manner with the upper arc plate and the lower arc plate, and the three arc plates are fixedly connected through pins. The beneficial effects of the utility model are as follows: Through using arc long chain and chain cooperation, can make oil cleaner dismouting spanner's suitability higher, the purpose of spanner multi-size adjustment can be satisfied in the setting of chain promptly, and the setting of arc long chain can improve the commonality of spanner, prevents to warp oil cleaner clamp in the use, makes the spanner more stable in the use, avoids appearing the phenomenon of tripping. Meanwhile, the wrench for disassembling the engine oil filter disclosed by the application is simple in structure, lower in maintenance cost and more convenient to use, and the problem of sm
