DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a special oil filter plier for attaching and detaching a cartridge for an oil filter of an automobile.

[0002]

2. Description of the Related Art Various tools have been proposed for attaching and detaching an oil filter of an automobile, and there are various types of commercially available products. Focusing on ease of use, on the other hand, engaging teeth are provided at the tip and base of the right holding piece, and opposite engaging teeth are provided at the tip of the left holding piece to provide a strong gripping force by a three-point holding method. It is to provide a secured oil filter pliers.

[0003]

The gist of the present invention will be described with reference to the accompanying drawings.

On the upper part of the left handle 1, a curved neck handle 2 having a thickness of about 薄 which is thinner and curved downward is continuously provided. A right engaging piece 3 which is curved in an arc shape is continuously provided, and a tooth engaging tip of a sawtooth shape is formed such that teeth protrude downward when viewed from the side inside the distal end portion and the base portion of the right holding piece 3. 4 and a base engaging tooth 5 are arranged in multiple stages with respect to one width, and a bent neck handle 7 having a thickness reduced by about 1/2 and bent at a substantially right angle is continuously provided on the upper part of the right handle. A left clamping piece 8 curved in an arc shape having substantially the same thickness as that of the right grip 6 is connected to the upper part of the bent neck handle 7, and the teeth of the left clamping piece 8 face upward inside the tip of the left gripping piece 8 when viewed from the side. The protruding saw-tooth-shaped counter-engaging teeth 9 are arranged in multiple stages with respect to one width, and the opposing position of the opposite-engaging teeth 9 is the base engaging with the tip engaging teeth 4 of the right holding piece 3. Position between teeth 5 Those of the oil filter pliers, characterized in that the pivotally mounted by a shaft 10 overlapping the curved neck handle 2 and bent neck handle 7 in relation that.

[0005] The left, middle and right three bearing holes 11 are formed in the bent neck handle 7.
The right holding piece 3 and the left holding piece 8 are provided by a shaft 10 having a chamfered portion 14 formed on both sides slidably with respect to a narrow space 13 provided between the bearing holes 11. 2. The oil filter plier according to claim 1, wherein the oil filter pliers are pivotally mounted so that the facing distance can be changed in three steps.

[0006]

[Function] When the right handle 6 is opened with respect to the left handle 1, the bent neck handle 7 is freely slidable by the pivotally attached long window 12 with respect to the shaft 10, and one of left, middle and right is selected. Can be used to pivotally connect the curved neck handle 2 and the bent neck handle 7.
And the distance between the left and right holding pieces 8 becomes narrower,
If the inside is selected, the pliers become the middle of the narrow and wide, and if the outer periphery of the oil filter is clamped by the right holding piece 3 and the left holding piece 8, the tip engaging teeth 4, the base engaging teeth 5, and the opposite engaging teeth 9 become outer circumferential This is a three-point clamping style that bites into the surface, and the respective front engagement teeth 4, base engagement teeth 5, and opposite engagement teeth 9 act to bite in the rotation direction to prevent sliding. Demonstrate strong turning power.

[0007]

FIG. 1 shows a preferred embodiment of the present invention. A left neck handle 1 is provided with a curved neck handle 2 having a thickness of about 1/2 and being curved downward at an upper portion thereof. On the upper part of the curved neck handle 2, a right holding piece 3 curved in an arc shape having substantially the same thickness as the left handle 1.
The right engaging piece 3 is provided with a saw tooth-shaped tip engaging tooth 4 and a base engaging tooth 5 having teeth protruding downward when viewed from the side inside the distal end and the base of the right holding piece 3. A bent neck handle 7 having a thickness of about 1/2 and being bent at a substantially right angle is continuously provided on the upper part of the right handle 6 at the upper part of the right handle 6. Left clamping piece 8 curved in the shape of an arc of approximately the same thickness as handle 6
The opposite engaging teeth 9 in the form of saw teeth, whose teeth protrude upward when viewed from the side surface, are arranged in parallel with the width of one side on the inner side of the tip of the left holding piece 8. The curved neck handle 2 and the bent neck handle 7 are overlapped with each other by the shaft 10 so that the opposite engagement teeth 9 are positioned between the tip engagement teeth 4 and the base engagement teeth 5 of the right holding piece 3. The present invention relates to an oil filter plier characterized by being worn.

The thickness of the curved neck handle 2 and the bent neck handle 7 is set to 1 /
When thinning about two, the left handgrip 1 and the right handgrip 6 are configured to be in front of each other when the inner meat that rubs against each other is dropped and overlapped, and the left handgrip 1 and the right handgrip 6 are in front of each other. 6 is coated with a colored synthetic resin film 15 to make it easy to hold and to improve the appearance. The shaft 10 is a tack-rod style bolt and a washer nut 16
Are screwed together to prevent swaging.

FIG. 1 is a front view of a state in which an oil filter having a diameter of about 60 mm is sandwiched, and FIG. 2 is a front view of a state in which an oil filter having a diameter of about 90 mm is sandwiched. For this purpose, the left handle 1 and the right handle 6 have a facing distance of about 5 mm to 20 mm.

When the shaft 10 is positioned in the left bearing hole 11, an oil filter having a diameter of about 70 mm can be held.
When 10 is located in the center bearing hole, an oil filter having a diameter of about 80 mm can be held.

[0011]

As described above, the present invention is an oil filter plier having excellent practicality and having the following features.

There are three portions for holding the cartridge, and one of the opposite engaging teeth is opposed at an intermediate position between the other of the front engaging teeth and the base engaging teeth. As a result, the cartridge can be quickly and easily attached and detached because of the strong clamping force.

In addition, since each of the tooth teeth of the front engagement tooth, the base engagement tooth, and the opposite engagement tooth is protruded in a direction to bite into the outer peripheral surface of the filter with respect to the turning power, it does not slide. It will exert a powerful turning power.

The opposed diameter of the right holding piece and the left holding piece can be adjusted to three stages of large diameter, middle diameter and small diameter by switching the shaft to the right, middle and left of the pivotal long window, so that the size of the cartridge can be reduced. Can be used regardless.

[0015] Even if the width of the left and right handle grips is any diameter, they are narrow and oppose each other, so it is easy to grip.

[0016] Since the pivotal windows are arranged horizontally at right angles to the right handle, the ends of the left and right handles have the same length in any of the left, middle and right.

Since it is made lightweight and compact, it can be easily operated even in a narrow place.
