By adjusting the internal sliding block, extrusion block and spring to accommodate lenses of different sizes, this flexibility allows a single protective cover to fit multiple models of lenses without having to customize different protective covers for each lens, simplifying the accessory management of the protective cover and improving the versatility of the protective cover. The internal adjustable parts of the protective cover combined with the anti-slip texture of the extrusion block ensure a secure fit even when the inner diameters of the lenses are different, making it compatible with a wide range of lens types and improving the overall compatibility of the device. Through the mutual cooperation of the coated rubber ring and the extrusion block, the protective cover can be firmly fixed on the lens, providing comprehensive protection against collisions, scratches and other risks that may cause damage to the lens;

[0014] Second, the user puts the fixing ring on the camera lens to ensure that the protective cover will not be lost after it is removed. The limit rod restricts the spring so that the spring will not deviate when it contracts and rebounds, which improves the stability of the extrusion block when fixing the protective cover. The rubber pad ensures that when the protective cover contacts the edge of the camera lens, it will not cause bumps on the edge, thereby improving the practicality of the overall device.

[0015] Third, by DIY manufacturing the outer surface of the rubber ring, users can customize the protective cover according to their own preferences or needs, making the equipment equipped with the device stand out and reflecting the style of the user. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1-Figure 4 As shown, a camera lens protective cover comprises a fixing hole 2, wherein the fixing hole 2 is penetrated and opened on the outer wall surface of the protective cover 1, two sliding blocks 3 are slidably arranged inside the fixing hole 2, a limiting opening 4 is arranged on the inner bottom surface of the protective cover 1, and the limiting opening 4 is communicated with the fixing hole 2, two connecting blocks 5 are slidably arranged on the inner bottom surface of the protective cover 1, and extrusion blocks 6 are respectively fixed at two ends of the two connecting blocks 5 away from each other, the top surface of the sliding block 3 is fixed to the bottom surface of the connecting block 5, a spring 7 is arranged between the two sliding blocks 3, and the two extrusion blocks 6 are mutually Both sides away from each other are provided with anti-slip grooves, the inner wall bottom surface of the fixing hole 2 is provided with a sliding opening 8, a pinching block 9 is fixed to the bottom surface of the sliding block 3, the bottom end of the pinching block 9 hangs through the sliding opening 8 and extends to the outer bottom surface of the protective cover 1, and a coated rubber ring 16 is fixed to the top surface of the protective cover 1. The coated rubber ring 16 is made of rubber material, and the diameter of the top circle of the coated rubber ring 16 is smaller than the diameter of the bottom circle. The outer surface of the coated rubber ring 16 can be DIY-made, and through DIY, users can customize the protective cover 1 according to their own preferences or needs. Make the equipment equipped with the device stand out and reflect the style of the user.

[0023] During use, the user turns the covering rubber ring 16 from the inside out, and uses the thumb and index finger to pinch the two pinching blocks 9 to move them closer to each other. When the two pinching blocks 9 move closer to each other, the two sliding blocks 3 move closer to each other. At this time, the two connecting blocks 5 and the two squeezing blocks 6 move closer to each other inside the protective cover 1. At this time, the two sliding blocks 3 squeeze the two ends of the spring 7, and the spring 7 is in a compressed state. At this time, the user covers the protective cover 1 on the lens of the camera, and the user can loosen the pinching block 9, and the two squeezing blocks 6 are moved closer by the rebound force of the spring 7. The edge of the camera lens is pressed against the anti-skid pattern on the outer wall of the extrusion block 6, and the thread on the inner wall of the camera lens is abutted against the thread on the inner wall of the camera lens, thereby fixing the protective cover 1 on the camera lens. At this time, the staff can reset the opening of the covering rubber ring 16, so that the covering rubber ring 16 can be wrapped around the outer wall of the camera lens. The camera lens is wrapped by the covering rubber ring 16, ensuring that the protective cover 1 will not fall off even if it is bumped after being fixed, thereby ensuring that the camera lens is protected;

[0024] By adjusting the internal sliding block 3, squeezing block 6 and spring 7 to accommodate lenses of different sizes, this flexibility allows a single protective cover to fit multiple types of lenses without having to customize a different protective cover 1 for each lens, which simplifies the accessory management of the protective cover 1 and improves the versatility of the protective cover 1. The internal adjustable parts of the protective cover 1 combined with the anti-slip texture of the squeezing block 6 ensure a secure fit even when the inner diameter of the lens is different, making it compatible with a wide range of lens types and improving the overall compatibility of the device. Through the mutual cooperation of the covering rubber ring 16 and the squeezing block 6, the protective cover 1 can be firmly fixed on the lens, providing comprehensive protection against collisions, scratches and other risks that may cause damage to the lens.

[0025] like Figure 1-Figure 4 As shown, a limiting hole 11 is opened on one side of the connecting block 5, a limiting rod 10 is movably sleeved between the two limiting holes 11, the spring 7 is movably sleeved on the outer wall of the limiting rod 10, two fixing blocks 12 are fixed inside the fixing hole 2, the two ends of the limiting rod 10 are respectively fixed to the two fixing blocks 12, a connecting rope 13 is fixed to the outer wall of the protective cover 1, a fixing ring 14 is fixed to one end of the connecting rope 13, anti-slip pads 15 are respectively fixed on both sides of the two pinching blocks 9 away from each other, and a rubber pad 17 is fixed inside the protective cover 1.

[0026] During use, the user puts the fixing ring 14 on the lens of the camera to ensure that the protective cover 1 will not be lost after being removed. The limit rod 10 restricts the spring 7 so that the spring 7 will not deviate when it contracts or rebounds, thereby improving the stability of the extrusion block 6 when fixing the protective cover 1. The rubber pad 17 ensures that when the protective cover 1 contacts the edge of the camera lens, it will not cause bumps on the edge, thereby improving the practicality of the overall device.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
