DETAILED DESCRIPTION

[0025] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0026] The utility model provides a kind of oil filter dismounting wrench, including the handle 1 of cylinder type, the top end of handle 1 is rotatably connected with arc-shaped long chain one 2, the end of arc-shaped long chain one 2 away from handle 1 is rotatably connected with arc-shaped long chain two 3, the end of arc-shaped long chain two 3 away from arc-shaped long chain one 2 is rotatably connected with arc-shaped long chain three 4.Arc-shaped long chain three 4 away from the end of arc-shaped long chain two 3 is hinged with chain 5.

[0027] Slidingly connected with slide cylinder 6 in handle 1, opening 11 is set on the side wall of handle 1, the end of chain 5 away from arc-shaped long chain three 4 is threaded through opening 11 and rotatably connected with slide cylinder 6, locking mechanism 61 is installed on slide cylinder 6, to be used for locking the sliding of slide cylinder 6, to realize the length of chain 5 to be controlled to the outside of opening 11, further realize the purpose of adjusting the size of wrench use.

[0028] Locking mechanism 61 includes clamping column 611, clamping column 611 is perpendicular to handle 1, and clamping column 611 is set through slide cylinder 6, clamping column 611 can slide relative to clamping cylinder.A row of clamping holes 12 and a sliding groove 13 are set on the side wall of handle 1, a row of clamping holes 12 and sliding groove 13 are symmetrically set about the axis of handle 1, one end of clamping column 611 is integrally provided with adjusting cap, one end of clamping column 611 adjusting cap is placed in sliding groove 13, the other end of clamping column 611 is placed in any one clamping hole 12, it needs to be explained that adjusting cap is set outside sliding groove 13, and the diameter of adjusting cap is greater than the width of sliding groove 13.

[0029] The coaxial sleeve on the clamping column 611 is provided with a spring 612, and the clamping column 611 is also welded with a stop rod 613 which is perpendicular to the clamping column 611. The spring 612 and the stop rod 613 are arranged in the sliding cylinder 6, one end of the spring 612 abuts against the stop rod 613, and the other end abuts against the inner wall of the sliding cylinder 6.

[0030] When the adjusting cap is pulled in a direction away from the handle 1, the end of the clamping column 611 away from the adjusting cap is pulled out of the clamping hole 12, the spring 612 is compressed, and then the clamping column 611 can be pushed to slide in the direction of the sliding groove 13 at this time. When it slides to the appropriate position, the clamping column 611 corresponds to the nearest clamping hole 12, and then the adjusting cap is released. Under the action of the elastic force of the spring 612, the clamping column 611 can be clamped into the clamping hole 12 again. It should be noted that the end of the clamping column 611 away from the adjusting cap will not be completely pulled into the sliding groove 13.

[0031] The arc-shaped long chain one 2, the arc-shaped long chain two 3 and the arc-shaped long chain three 4 are all arranged in the same structure. The inner arc surface of the arc-shaped long chain one 2 is provided with anti-skid teeth. The arc-shaped long chain one 2 includes three arc plates arranged from top to bottom, and the three arc plates are fixedly connected by two pins. The curvature of the arc plate is set as a quarter of a circle, and the upper and lower two arc plates are correspondingly arranged, and the middle arc plate is arranged in a staggered manner with the upper and lower two arc plates, that is, one end of the middle arc plate is arranged in an extended manner.

[0032] One end of the middle arc plate of the arc-shaped long chain one 2 is rotatably connected with the handle 1, one end of the middle arc plate of the arc-shaped long chain two 3 is rotatably connected with the arc-shaped long chain one 2, and one end of the middle arc plate of the arc-shaped long chain three 4 is rotatably connected with the arc-shaped long chain two 3.

[0033] Reference Figure 4 One use state of the wrench disclosed in the present application is that when in use, one end of the handle 1 close to the arc-shaped long chain one 2 is abutted against the side wall of the oil filter, then the arc-shaped long chain one 2, the arc-shaped long chain two 3, the arc-shaped long chain three 4 and the chain 5 are collectively sleeved outside the oil filter, and then the handle 1 is pulled. At this time, one end of the handle 1 abutting against the oil filter can be regarded as the fulcrum of force, the handle 1 is rotated in the counterclockwise direction, the chain 5 is pulled by the handle 1, and the arc-shaped long chain one 2, the arc-shaped long chain two 3 and the arc-shaped long chain three 4 are driven by the chain 5, so as to realize the locking of the oil filter together with the chain 5, so as to drive the oil filter to rotate together with the wrench to realize the disassembly and assembly. Under the pulling of the chain 5, the force pushing the handle 1 acts on the arc-shaped long chain one 2, the arc-shaped long chain two 3 and the arc-shaped long chain three 4 at the same time, so that they are locked, and the phenomenon of tripping can be avoided when the handle 1 is pushed.

[0034] It should be noted that the wrench of the present application is used, the axis of the handle 1 should deviate from the center of the oil filter, that is, the extension line of the axis does not pass through the center of the circle. Under the premise of meeting this use requirement, the wrench of the present application can also deviate the axis of the handle 1 to the right side of the center of the oil filter, that is, the axis of the handle 1 is deviated to the left side of the center of the circle. The handle 1 axis deviated to the left side of the center of the circle is the method used in the disassembly process of the small-diameter filter, and the handle 1 axis deviated to the right side of the center of the circle is the method used in the disassembly process of the large-diameter filter. Figure 4 As a reference, the handle 1 axis is deviated to the left side of the center of the circle. The handle 1 axis deviated to the left side of the center of the circle is the method used in the disassembly process of the small-diameter filter, and the handle 1 axis deviated to the right side of the center of the circle is the method used in the disassembly process of the large-diameter filter.

[0035] It should also be noted that, Figure 4 The process shown in the figure is the disassembly process of the filter, that is, the card hole 12 is upward at this time, and during installation, only the sliding groove 13 of the wrench is upward to realize the installation process.

[0036] In summary, the present application can make the adaptability of the oil filter disassembly wrench higher by using the arc-shaped long chain in cooperation with the chain 5, that is, the setting of the chain 5 can meet the purpose of adjusting the size of the wrench, and the setting of the arc-shaped long chain can improve the versatility of the wrench, make the wrench more stable during use, and avoid the phenomenon of tripping. At the same time, the oil filter disassembly wrench disclosed by the present application has the advantages of simple structure, lower maintenance cost, convenient use, fine adjustment, small gap between adjacent gears, and larger wrench clamping torque in the range, so that the installation and disassembly are simple.
