[0024] Example:

[0025] Reference Figure 1-Figure 4, an ETC monitoring fixed device, a dedicated short-range communication between the vehicle-mounted electronic tag on the vehicle windshield and the microwave antenna on the ETC lane at the toll station, using computer networking technology to conduct back-end settlement processing with the bank, so that the vehicle can pay the highway or bridge fee without stopping at the highway or bridge toll station, and the existing ETC device generally has a driving recorder function, which needs to be installed on the car and on the back of the rearview mirror inside the car, so that it can record the video image and The sound can provide evidence for traffic accidents, including a first limiting plate 1, at the corner position of the first limiting plate 1 is also fixedly connected to a contact plate 101, and the contact surface of the contact plate 101 is an anti-skid pad, the anti-skid pad is usually made of rubber, silicone, rubber film and other materials, so that the bottom of the anti-skid pad can be against the outer wall of the interior rearview mirror, so as to effectively reduce the friction and scratches on the outer wall surface of the interior rearview mirror when the first limiting plate 1 moves back and forth on the outer wall of the interior rearview mirror, thereby protecting the outer wall of the interior rearview mirror from damage, and at the same time can also improve the limiting effect of the first limiting plate 1.

[0026] Also, please refer to Figure 2 As shown in, in order to better stabilize the ETC, two groups of first limit plates 1 are provided in the device, and the two groups of first limit plates 1 are fixedly connected by a connecting rod. A cavity 102 is also opened in the first limit plate 1, and an extension rod 2 is slidably connected to the first limit plate 1, and the cross-section of the extension rod 2 can be rectangular or circular, and then one end of the extension rod 2 is extended into the cavity 102 and fixedly connected with a movable block 201, and the outer wall of the movable block 201 is always in contact with the inner wall of the cavity 102, and a spring 3 is sleeved on the extension rod 2, and the diameter of the spring 3 is larger than the cross-section of the extension rod 2, and it also needs to be arranged inside the cavity 102, and then the two ends of the spring 3 are respectively fixedly connected to the movable block 201 and the first limit plate 1, when the extension rod 2 is stretched and moved downward, the movable block 201 will compress the spring 3, and when the extension rod 2 needs to be reset, the extension rod 2 can be returned, and at this time the spring 3 will automatically drive the extension rod 2 to be retracted into the cavity 102.

[0027] For explanation, please refer to Figure 4As shown in, a second limit plate 4 is fixedly connected to the other end of the extension rod 2, and a friction pad is provided at the end of the second limit plate 4, which can cooperate with the contact plate 101. When the first limit plate 1 needs to be installed on the interior rearview mirror, the second limit plate 4 can be stretched downward, and then the contact plate 101 can be clamped on the outer wall of the interior rearview mirror. Subsequently, the extension rod 2 is affected by the spring 3, which will drive the contact surface of the second limit plate 4 to abut against the bottom of the interior rearview mirror, thereby realizing the clamping of the interior rearview mirror by the first limit plate 1 and the second limit plate 4. When the first limit plate 1 needs to be disassembled, the extension rod 2 can be stretched downward, and then the contact plate 101 can be removed from the interior rearview mirror, thereby realizing the detachable function, improving the practicability of the device, and allowing its staff or car owners to disassemble and install the first limit plate 1 more conveniently.

[0028] Also, please refer to Figure 2 and Figure 3 As shown in, a mounting plate 5 is fixedly connected to the second limiting plate 4, a limiting seat 6 is fixedly connected to the mounting plate 5, and the rotating seat 7 is rotatably connected to the limiting seat 6 via a rotating shaft 601, and the rotating connection between the rotating seat 7 and the limiting seat 6 is an interference fit, which means that the dimensions of the two parts are designed to be very close, wherein the connecting hole of the rotating seat 7 is slightly smaller, and the rotating shaft 601 is slightly larger, so that they need to apply a certain force during assembly to fit each other, thereby achieving an interference fit effect, and an ETC body 8 can be placed on the rotating seat 7 for limiting and fixing the ETC body 8, and a locking bolt 701 is threadedly connected to the rotating seat 7, and the limiting effect on the ETC body 8 can be achieved by the contact end of the locking bolt 701 being against the outer wall of the ETC body 8.

[0029] The working principle is as follows. When the ETC body 8 needs to be installed, the contact plate 101 can be stuck on the outer wall of the interior rearview mirror, and then the extension rod 2 is pulled so that the extension rod 2 drives the second limit plate 4 to move downward. At this time, the second limit plate 4 is abutted against the bottom outer wall of the interior rearview mirror, and then the ETC body 8 is installed on the rotating seat 7, and the locking degree of the locking bolt 701 is adjusted and rotated according to the size of the ETC body 8, so that it can be suitable for ETC bodies 8 of different sizes, thereby improving the practicality of the device. Then, the position of the ETC body 8 is rotated and adjusted so that it can play the role of a driving recorder. Through the cooperation of the first limit plate 1 and the second limit plate 4, the ETC body 8 can be installed on the interior rearview mirror, and the installation process is simple, the installation is firm, and it can be easily disassembled without the need for additional power supply.
