Furthermore, the charging and other functions are not designed reasonably, reducing the user experience and testing efficiency of the device. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, this utility model provides a clamping motor vehicle exhaust gas detection device. By setting up clamping and fixing components and optimizing the structure of the detection mechanism, it solves the problems of unstable clamping, inconvenient operation, and low detection efficiency mentioned in the background technology.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a clamping motor vehicle exhaust gas detection device, comprising a detection mechanism, wherein a clamping and fixing component is connected to the detection mechanism.

[0007] The detection mechanism includes an exhaust gas detector. One end of the detector has an air intake slot, and multiple air intake slots are arranged in an array at the center of one end of the detector to facilitate comprehensive and efficient intake of vehicle exhaust gases. The other side of the detector has exhaust slots at both the top and bottom, and a group of multiple exhaust slots are also arranged in an array on the outside of the detector to quickly expel the detected gas and ensure continuous detection. The exhaust gas detector is connected to a controller via a control line. A connecting wire frame, which is a flexible, shaped metal tube, is fitted around the control line, with its two ends fixedly connected to the exhaust gas detector and the controller, respectively, allowing the control line to travel... The controller can be flexibly adjusted according to needs, improving the flexibility of its use. A display screen is located on one side of the top of the controller for intuitively displaying exhaust gas detection data. Multiple control buttons are located on the other side of the top of the controller for convenient function selection and operation. A non-slip grip handle is fixedly connected to the other end of the controller. The non-slip grip handle has an ergonomic arc-shaped structure and its outer surface has anti-slip textures, improving grip comfort and anti-slip effect, facilitating long-term operation. The controller has a built-in lithium battery, and a charging interface is located at the front of the controller that is electrically connected to the internal lithium battery charging circuit, enabling convenient charging of the device and ensuring battery life.

[0008] The clamping and fixing assembly includes connecting plates fixedly connected to the upper and lower sides of both ends of the exhaust gas detector. Two telescopic rods are symmetrically fixedly connected to the two connecting plates on the same side at one end. A spring is sleeved on the outer side of each telescopic rod. One end of the spring is fixedly connected to the connecting plate, and the other end is fixedly connected to an inner clamping block. The elasticity of the spring provides buffering and stable clamping force. An inner clamping block is fixedly connected to the movable end of the telescopic rod away from the connecting plate. One end of the inner clamping block has a chamfer for quick alignment and insertion into the vehicle's exhaust emission area. Multiple anti-slip grooves are formed on the outer wall of the inner clamping block away from the telescopic rod. These anti-slip grooves are parallel and have a semi-circular cross-sectional shape, increasing friction with the clamping area and improving clamping stability.

[0009] As a further improvement of this utility model, the inner clamping block is made of rubber material. Rubber has good elasticity and wear resistance, which can not only enhance the adaptability of clamping, but also extend the service life of the inner clamping block.

[0010] As a further improvement of this utility model, the display screen adopts a high-brightness LED display screen, which can clearly display the detection data even in a strong light environment, thereby improving the convenience of data reading.

[0011] As a further improvement of this utility model, the control line is a bend-resistant shielded line, which has good anti-interference performance and bend resistance, ensuring the stability of signal transmission and service life.
