Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a tool for removing automotive tires. Background Technology

[0002] Car tires are ring-shaped elastic rubber products mounted on the rims of vehicles. As the only part of the vehicle in contact with the ground, they bear core functions such as support, driving, braking, and shock absorption. However, to ensure a tight connection between the tire and the rim during driving and to guarantee driving safety, the lug nuts of car tires are usually tightened very tightly. But when a car tire is damaged and needs to be removed and replaced, it is difficult to directly loosen these lug nuts by hand alone. Therefore, corresponding disassembly tools are required, such as tire wrenches and socket wrenches.

[0003] However, existing tire wrenches, especially some one-piece molded tire wrenches, are difficult to fold and adjust, making them take up a lot of space when carried. In addition, when using tire wrenches to remove tire bolts, especially when the tire bolts are rusty and difficult to loosen, excessive force can easily cause the tire wrench to slip.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] The main purpose of this utility model is to provide a car tire removal tool that can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A car tire removal tool includes a fixed base, with folding devices fixedly installed at the left and right ends of the fixed base. A first connecting arm is fixedly installed at the opposite ends of the two folding devices, and a first wrench head is fixedly installed at the opposite ends of the two first connecting arms. A second connecting arm is inserted and fixedly installed at the middle of the front end of the fixed base. A second wrench head is fixedly installed at the front and rear ends of the second connecting arm. Anti-slip textures are engraved on the outer surfaces of the two first connecting arms and the second connecting arm.

[0008] Preferably, the folding device includes a connecting seat, a connecting column is fixedly installed through the middle of the upper end of the connecting seat, a connecting plate is rotatably installed on the outer surface of the connecting column, a first bolt is installed on the upper end of the connecting plate, and a first screw hole is opened on the upper right and upper front of the connecting seat. The connecting seat is fixedly installed on the right end of the fixed seat. By loosening the first bolt, the first connecting arm can be rotated and adjusted on the connecting column in the connecting seat through the connecting plate. When the first connecting arm is parallel to the second connecting arm, the unscrewed first bolt is screwed into the corresponding first screw hole on the connecting seat. This not only fixes the first connecting arm, but also allows the first connecting arm to be folded up, thereby reducing the size of the tire wrench.

[0009] Preferably, a second bolt is installed on the upper right side of the first connecting arm, and a second screw hole is opened on the upper left side of the first wrench head. The first wrench head is fixedly installed on the right end of the first connecting arm by the second bolt. The first wrench head can be replaced by loosening the second bolt, and similarly, the second wrench head can be replaced by loosening the third bolt.

[0010] Preferably, both the front and rear ends of the upper part of the second connecting arm are equipped with No. 3 bolts, and both ends of the two No. 2 wrench heads are drilled with No. 3 threaded holes. The two No. 2 wrench heads are respectively inserted and fixed to the front and rear ends of the second connecting arm by No. 3 bolts. The tire wrench has an overall cross-shaped design, which makes it easier and less strenuous to turn the tire wrench. In addition, the outer surfaces of both the first and second connecting arms are engraved with anti-slip textures, which provides better anti-slip properties when using the tire wrench.

[0011] Preferably, when the first connecting arm is deployed, the angle between the first connecting arm and the second connecting arm is ninety degrees.

[0012] Preferably, the connecting plate is movably installed in the connecting seat, and the right end of the connecting plate is fixedly connected to the first connecting arm.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. By loosening the first bolt of the folding device, the first connecting arm can be rotated and adjusted on the connecting column in the connecting seat through the connecting plate on it. When the first connecting arm and the second connecting arm are parallel, screw the unscrewed first bolt into the corresponding first screw hole on the connecting seat. This not only fixes the first connecting arm, but also allows the first connecting arm to be folded up, thereby reducing the size of the tire wrench and making it easier to carry.

[0015] 2. After aligning the wrench head with the tire bolt and inserting it, the overall cross-shaped design of the tire wrench makes it easier and less strenuous to turn. Furthermore, the outer surfaces of both the first and second connecting arms are engraved with anti-slip textures, providing better grip. Additionally, the two second wrench heads at the front and rear ends of the first connecting arm, and the first wrench head on the second connecting arm, are of different specifications to accommodate different types of tire bolts. Moreover, the wrench heads are all mounted to their corresponding connecting arms via bolts. When a wrench head is damaged or needs to be replaced with a different size, simply loosen the corresponding bolt. Attached Figure Description
