TECHNICAL FIELD
[0001] The utility model relates to the field of spark plug sleeve, more specifically, to a spark plug sleeve convenient to disassemble. BACKGROUND
[0002] The function of the spark plug is to introduce high-voltage electricity of tens of thousands of volts into the combustion chamber and generate an electric spark to ignite the mixture, cooperate with the ignition system and oil supply system to make the engine work. When disassembling the spark plug, a professional hex socket wrench, commonly known as a spark plug sleeve, is needed. When using the spark plug sleeve, first select the sleeve head size that matches the spark plug, then insert the sleeve head into the sleeve, align the spark plug and perform a rotating operation to disassemble or install the spark plug.
[0003] Most of the current spark plug sleeves are of one-piece structure, which requires operators to purchase multiple types of spark plug sleeves to adapt to different spark plugs. This occupies more space when storing and increases the purchase cost of equipment. SUMMARY

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a spark plug sleeve convenient to disassemble. The present scheme can use different sizes of spark plug sleeves, reducing the need to carry multiple spark plug sleeves when replacing spark plugs, and facilitating disassembly, thereby improving work efficiency and use convenience.
[0006] 2. Technical scheme
[0007] To solve the above problems, the utility model adopts the following technical scheme.
[0008] A detachable spark plug sleeve includes a universal handle. A retaining sleeve is fixedly connected to the lower end of the universal handle. A sliding ring is fitted onto the outer end of the retaining sleeve, and the sliding ring is slidably connected to the retaining sleeve. A spark plug sleeve is located at the lower end of the sliding ring. An installation groove is formed at the upper end of the spark plug sleeve. A retaining block is located inside the installation groove. A limit hole is formed at the upper end of the retaining block. A pair of L-shaped plates are provided at the bottom of the retaining sleeve. A first slider is fixedly connected to the upper end of the pair of L-shaped plates. A first sliding groove is formed at the bottom of the retaining sleeve, and the first sliding groove is slidably connected to the first slider. A first compression spring is installed inside the first sliding groove. A trapezoidal block is provided inside the retaining sleeve. The bottom of the trapezoidal block... The upper end of the sleeve is fixedly connected to the upper end of the first slider. A limiting rod is fixedly connected to the bottom of the sleeve. The limiting rod is located between a pair of L-shaped plates. A second sliding groove is opened at the outer end of the sleeve. A second slider is slidably connected inside the second sliding groove. A second compression spring is installed inside the second sliding groove. The second compression spring is located at the lower end of the second slider. A connecting rod is fixedly connected to the lower end of the second slider. A roller is installed at the bottom end of the connecting rod. The roller contacts the inclined surface of the trapezoidal block. This solution can use spark plug sleeves of different sizes. When changing spark plugs, it reduces the need to carry multiple spark plug sleeves and facilitates disassembly, thereby improving work efficiency and ease of use.
[0009] Furthermore, a rubber layer is fixedly connected to the outer end of the sliding ring, and the outer end of the rubber layer is provided with anti-slip texture. When sliding the sliding ring, the friction between the palm and the sliding ring is increased, which facilitates better sliding of the sliding ring and further improves work efficiency.
[0010] Furthermore, the inner wall of the limiting hole and the outer end of the limiting rod are matched and are both hexagonal in shape to limit the spark plug sleeve, thereby improving the replacement efficiency when replacing the spark plug.
[0011] Furthermore, the bottom sides of the pair of L-shaped plates that are close to each other are provided with a 45° inclined surface, which allows the L-shaped plates to better engage with the locking block.
[0012] Furthermore, a sponge layer is bonded to the bottom of the limiting rod to improve the stability of the contact between the limiting rod and the limiting hole.
[0013] Furthermore, the L-shaped plate is made of high-strength steel, and the inner wall of the L-shaped plate matches the outer side of the card block, giving it better strength and thus reducing the probability of deformation of the L-shaped plate.

[0031] Example 1:
[0032] Please see Figures 1-4A spark plug sleeve for easy disassembly includes a universal handle 1. A retaining sleeve 2 is fixedly connected to the lower end of the universal handle 1. A sliding ring 3 is fitted onto the outer end of the retaining sleeve 2, and the sliding ring 3 is slidably connected to the retaining sleeve 2. A spark plug sleeve 4 is located at the lower end of the sliding ring 3. An installation groove is formed at the upper end of the spark plug sleeve 4, and a retaining block 5 is provided inside the installation groove. A limit hole 6 is formed at the upper end of the retaining block 5. A pair of L-shaped plates 9 are provided at the bottom of the retaining sleeve 2. A first slider 701 is fixedly connected to the upper end of the pair of L-shaped plates 9. A first sliding groove 7 is formed at the bottom of the retaining sleeve 2, and the first sliding groove 7 is slidably connected to the first slider 701. A first pressure... The sleeve 2 has a trapezoidal block 14 inside, the bottom end of which is fixedly connected to the upper end of the first slider 701. The bottom of the sleeve 2 is fixedly connected to a limit rod 10, which is located between a pair of L-shaped plates 9. The outer end of the sleeve 2 has a second slide groove 11, and the second slider 12 is slidably connected inside the second slide groove 11. The second compression spring 13 is installed inside the second slide groove 11 and is located at the lower end of the second slider 12. The lower end of the second slider 12 is fixedly connected to a connecting rod 15, and a roller 16 is installed at the bottom end of the connecting rod 15. The roller 16 is in contact with the inclined surface of the trapezoidal block 14.
[0033] Please see Figures 1-3 The outer end of the sliding ring 3 is fixedly connected with a rubber layer, and the outer end of the rubber layer is provided with anti-slip texture. When sliding the sliding ring 3, the friction between the palm and the sliding ring 3 is increased, which facilitates better sliding of the sliding ring 3 and further improves work efficiency. The inner wall of the limiting hole 6 and the outer end of the limiting rod 10 are matched and are both hexagonal in shape, which limits the spark plug sleeve and improves the replacement efficiency when replacing spark plugs.
[0034] Please see Figures 2-3 The bottom of the pair of L-shaped plates 9 has a 45° inclined surface on the side that is close to each other, so that the L-shaped plates 9 can better engage with the locking block 5. The bottom of the limiting rod 10 is bonded with a sponge layer to improve the stability of the contact between the limiting rod 10 and the limiting hole 6. The L-shaped plates 9 are made of high-strength steel, and the inner wall of the L-shaped plates 9 matches the outer side of the locking block 5, so that it has better strength and thus reduces the probability of deformation of the L-shaped plates 9.
[0035] Working principle: When relevant technicians use this device, they first select a suitable spark plug sleeve 4, aligning the upper end of the spark plug sleeve 4 with the lower end of the retaining sleeve 2, so that the limiting rod 10 at the lower end of the retaining sleeve 2 is inserted into the limiting hole 6 to limit it. At the same time, the lower end of the L-shaped plate 9 is engaged with the bottom of the retaining block 5, so that the sliding ring 3 and the spark plug sleeve 4 are engaged, and the L-shaped plate 9 is limited by the first sliding groove 7, making it difficult for the spark plug sleeve 4 to fall off from the sliding ring 3, thereby improving stability. When it is necessary to disassemble and replace other spark plug sleeves, Grasp the sliding ring 3 and slide it to one side of the spark plug sleeve 4, so that the roller 16 inside the sliding ring 3 slides between the roller 16 and the trapezoidal block 14. The inclined surface of the trapezoidal block 14 causes the spark plug sleeve 4 to move to the outside of the housing, thereby contacting the locking between the L-shaped plate 9 and the locking block 5, which facilitates the disassembly of the spark plug sleeve 4. The L-shaped plate 9 is reset again through the first sliding groove 7. This solution can use spark plug sleeves of different sizes, reduce the need to carry multiple spark plug sleeves when changing spark plugs, and facilitate disassembly, thereby improving work efficiency and ease of use.
[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
