Description

Technical Field

[0001] This utility model relates to the field of automotive repair tools, and in particular to a more versatile oil filter removal tool. Background Technology

[0002] Currently, the oil filter is an essential component of fuel-powered vehicles. The oil filter housing typically has polygonal edges. When a car has traveled a certain amount of time or distance, the entire oil filter or its internal oil filter element needs to be replaced. Maintenance personnel need to use auxiliary tools to remove the oil filter from the vehicle. Currently, common auxiliary tools are generally cup-shaped. However, because different oil filters have different edge sizes, different cup-shaped removal tools are required, and these tools are prone to slipping during use, making it impossible to disassemble using the aforementioned cup-shaped tools. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and develop a more versatile oil filter removal tool.

[0004] This invention is implemented as follows: an oil filter removal tool, comprising a left jaw and a right jaw, characterized in that: each of the left and right jaws includes a base plate and a jaw, the jaw being disposed on one side surface of the base plate, and the base plates of the left and right jaws being connected to each other via a linear slide rail. It also includes connecting plates and sleeves. The base plates of the left and right jaws are connected to different connecting plates. The base plates of the left and right jaws can rotate with the connecting plates. The other end of the connecting plates connected to the base plates of the left and right jaws is eccentrically connected to the sleeve. The connection between the connecting plates and the sleeve can rotate.

[0005] Further optimization involves providing a preload spring between the left and right jaws, with the preload spring located on the front and / or rear side of the base plate.

[0006] Further optimization involves providing slots on the opposing jaw surfaces of the left and right jaws.

[0007] Further optimization involves providing a serrated groove on each jaw surface with the serrations facing the center (in the embodiment, the groove is described as running vertically).

[0008] Further optimization involves placing the top surface of these serrated grooves on the claw surface on an arc surface.

[0009] Furthermore, the connecting piece is strip-shaped, and connecting holes are provided at both ends of the connecting piece; The sleeve is a hexagonal sleeve, and two connecting pins are eccentrically arranged on the hexagonal sleeve.

[0010] This device has the following advantages: The extension distance between the left and right jaws can be adjusted by rotating the hexagonal sleeve to accommodate oil filters of different sizes. This device is easy to install, has a compact and simple structure, and the opening size between the left and right jaws is adjustable, increasing its applicability. The unique serrated grooves provide a firm and non-slip engagement, improving work efficiency. Attached Figure Description

[0016] Figure 6 This is a structural schematic diagram of the device viewed from below. Detailed Implementation

[0017] In this embodiment, with Figures 1 to 6 As shown, An oil filter removal tool includes a left jaw 1 and a right jaw 2. Each jaw 1 and right jaw 2 includes a base plate 3 and a jaw 4. The jaw 4 is fixedly mounted on one side of the base plate 3. The jaws 4 of the left jaw 1 and right jaw 2 face each other, forming a closed space. The base plates of the left jaw 1 and right jaw 2 are respectively provided with a slide rail and a slider. Through the cooperation of the slide rail and slider, the left jaw 1 and right jaw 2 move linearly via the linear slide rail, allowing the facing surfaces of the jaws 4 of the left jaw 1 and right jaw 2 to move closer or further apart.

[0018] A preload spring 5 is also provided between the left jaw 1 and the right jaw 2. In this embodiment, fixing rings 3-1 are provided on both the front and rear sides of the base plate 3, and a preload spring 5 is provided between the two fixing rings 3-1 on the same side. The preload spring 5 can be provided on only one side or on both sides. In this embodiment, in order to distribute the force more evenly, the preload spring 5 is provided on both sides. The preload spring 5 applies opposing tensions to the left jaw 1 and the right jaw 2, which helps the left jaw 1 and the right jaw 2 to more easily grip the housing of the oil filter.

[0019] The left jaw 1 and right jaw 2 have slots 6 on their opposing jaw surfaces. Referring to the orientation in the attached drawings of this embodiment, each jaw surface has a serrated slot 6 with the teeth pointing towards the center, and the slot 6 runs vertically up and down. The unique serrated slot 6 provides a firm and slip-resistant engagement, improving work efficiency. Further optimization is achieved through... Figure 6 It can be seen that the top surface of these serrated grooves on the jaw surface is on an arc surface, which is beneficial for clamping and holding oil filter housings of different sizes.

[0020] The device also includes a connecting piece 7 and a sleeve 8. The connecting piece 7 is strip-shaped and has connecting holes at both ends. The sleeve 8 is a hexagonal sleeve with two connecting pins eccentrically arranged on it.

[0021] like Figure 1 and Figure 5 As shown, the base plates of the left jaw 1 and the right jaw 2 are both connected to a connecting piece 7. That is, a rotating shaft 9 is provided on the back of the base plates of the left jaw 1 and the right jaw 2 near the edge. Through the rotating shaft 9, the left jaw 1 and the right jaw 2 are respectively hinged to a connecting piece 7. The left jaw 1, the right jaw 2 and the rotating shaft 9 can rotate. The sleeve 8 is located in the middle of the device. The other end of the two connecting pieces 7 are respectively connected to a connecting pin on the sleeve. The connecting pieces 7 and the connecting pin of the sleeve are hinged to each other. The connecting pieces 7 and the connecting pin of the sleeve can rotate.

[0022] During use, manually adjust the distance between the jaws 4 of the left jaw 1 and right jaw 2 according to the specifications of the oil filter housing to secure the device to the oil filter housing. Under the opposing pull of the pre-tension spring 5, the left jaw 1 and right jaw 2 more easily grip the oil filter housing. The operator inserts a hex wrench into the socket 8 and rotates it. The socket 8 rotates accordingly, causing the connecting plate 7 connected to it to rotate or shift towards the socket 8. This, in turn, causes the two connecting plates 7 to move the left jaw 1 and right jaw 2 towards each other, further securing the oil filter housing. With the operator applying force, the oil filter can be easily removed from the vehicle body. By changing the direction of the hex wrench rotation, the oil filter can be reinstalled on the vehicle body. The extension distance between the left and right jaws can be adjusted by rotating the hexagonal sleeve to accommodate oil filters of different sizes, increasing its applicability. The unique serrated grooves provide a firm and non-slip engagement, improving work efficiency.
