After the car anti-theft device is placed on the L-shaped clamping plate, the clamping component engages with the left side of the L-shaped clamping plate to clamp the car anti-theft device, enabling quick and firm fixation and improving detection efficiency. The rotating assembly can drive the support arm to rotate, thereby causing the L-shaped clamping plate to drive the car anti-theft device to rotate, adjusting the angle of the car anti-theft device and improving practicality.

[0005] Preferably, the clamping assembly includes an electric telescopic rod, a sliding plate, and a clamping plate. The electric telescopic rod is fixedly installed on the bottom right side of the L-shaped clamping plate. A clamping groove is provided on the top right side of the L-shaped clamping plate. The middle part of the sliding plate is slidably installed in the clamping groove. The lower part of the sliding plate is connected to the telescopic end of the electric telescopic rod. The clamping plate is fixedly connected to the top of the sliding plate. After the car anti-theft device is placed on top of the L-shaped clamping plate, the electric telescopic rod is activated to move the sliding plate in the clamping groove, thereby moving the clamping plate on top of the L-shaped clamping plate to clamp the car anti-theft device. The operation is simple and easy to clamp.

[0006] Preferably, the support arm has an internal cavity, and a piston plate is slidably installed inside the cavity. A telescopic rod is fixedly connected to the right side wall of the piston plate, and the telescopic rod slides through the L-shaped clamping plate.

A spring is located inside the support arm and is fitted onto the outer wall of the telescopic rod. One end of the spring is connected to the piston plate, and the other end of the spring is connected to the left side wall of the L-shaped clamping plate. After the car anti-theft device is placed on top of the L-shaped clamping plate, the left end of the car anti-theft device contacts the contact plate. When the clamping plate pushes the car anti-theft device to clamp, the car anti-theft device pushes the telescopic rod through the contact plate, causing the piston plate to move within the support arm, stretching the spring, ensuring the stability of the clamping, buffering the clamping force, and avoiding damage to the car anti-theft device.

[0007] Preferably, the limiting assembly includes two connecting plates, a rotating rod, a drive box, a knob, an adjusting plate, a limiting plate, and a servo motor.

The input end of the rotating rod is connected to the output end of the drive box, and a knob is installed at the input end of the drive box. Threaded grooves are symmetrically opened at the front and rear ends of the rotating rod. An adjusting groove is opened at the top of the L-shaped clamping plate at the position corresponding to the rotating rod. The adjusting plate is slidably installed in the adjusting groove, and the lower part of the adjusting plate is screwed into the threaded groove of the rotating rod. A limiting plate is fixedly connected to the top of the adjusting plate. A guide groove is opened on the side wall of the L-shaped clamping plate, and a guide slider is slidably installed in the guide groove. The guide slider is fixedly connected to the left side wall of the limiting plate. Rotating the knob drives the rotating rod to rotate through the drive box, causing the two adjusting plates to move closer or further apart, thereby causing the limiting plate to move back and forth at the top of the L-shaped clamping plate. This adjustment is made according to the size of the car anti-theft device, making the L-shaped clamping plate suitable for different models of car anti-theft devices.

[0008] Preferably, the rotating assembly includes a servo motor, a drive gear, a gear ring, and a protective cover.

A gear ring is mounted on the outer wall of the support arm, and the drive gear meshes with the gear ring. The protective cover is mounted on the left side wall of the fixed base, and the gear ring and drive gear are located inside the protective cover. Starting the servo motor drives the drive gear to rotate, and the drive gear drives the support arm to rotate via the gear ring. The support arm drives the car anti-theft device to rotate via an L-shaped clamping plate, allowing adjustment of the car anti-theft device's angle for ease of use.

[0009] Preferably, the bottom of the fixed seat is connected to a support rod, the bottom of the support rod is equipped with a ratchet turntable, and the lower part of the ratchet turntable is connected to a base plate; the support rod supports the fixed seat, and the ratchet turntable allows the fixed seat to rotate and adjust the direction of use.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: the limiting component can be adjusted according to the size of the car anti-theft device, so that the L-shaped clamping plate can be used for different models of car anti-theft devices. After the car anti-theft device is placed on the L-shaped clamping plate, the clamping component cooperates with the left side of the L-shaped clamping plate to clamp the car anti-theft device, which can be quickly and firmly fixed, improving detection efficiency. The rotating component can drive the support arm to rotate, thereby causing the L-shaped clamping plate to drive the car anti-theft device to rotate, adjusting the angle of the car anti-theft device and improving practicality.

The lower part of the sliding plate 5 is connected to the telescopic end of the electric telescopic rod 4. A clamping plate 6 is fixedly connected to the top of the sliding plate 5. A cavity is provided inside the support arm 2. A piston plate 8 is slidably installed inside the cavity of the support arm 2. A telescopic rod 7 is fixedly connected to the right side wall of the piston plate 8. The telescopic rod 7 slides through the L-shaped clamping plate 3. A contact plate 10 is fixedly connected to the right end of the telescopic rod 7. The contact plate 10 is slidably installed in the L-shaped clamping plate 3. On the upper surface of plate 3, spring 9 is located inside support arm 2 and is fitted onto the outer wall of telescopic rod 7. One end of spring 9 is connected to piston plate 8, and the other end of spring 9 is connected to the left side wall of L-shaped clamping plate 3. Two connecting plates 11 are fixedly installed at the front and rear ends of the bottom left side of L-shaped clamping plate 3. Rotating rod 12 is rotatably installed between the two connecting plates 11. The input end of rotating rod 12 is connected to the output end of drive box 13. A knob 14 is installed at the input end of drive box 13. Threaded grooves are symmetrically opened at the front and rear ends of rotating rod 12. L-shaped clamping plate 3 An adjustment groove is provided at the top of the rotating rod 12, and the adjustment plate 15 is slidably installed in the adjustment groove. The lower part of the adjustment plate 15 is screwed into the threaded groove of the rotating rod 12. The top of the adjustment plate 15 is fixedly connected to the limit plate 16. A guide groove is provided on the side wall of the L-shaped clamping plate 3. The guide slider is slidably installed in the guide groove.

After the car anti-theft device is placed on top of the L-shaped clamping plate 3, the left end of the car anti-theft device contacts the contact plate 10, activating the power supply. The telescopic rod 4 drives the sliding plate 5 to move within the clamping groove, thereby causing the clamping plate 6 to move on top of the L-shaped clamping plate 3. When the clamping plate 6 pushes the car anti-theft device to clamp, the car anti-theft device pushes the telescopic rod 7 through the contact plate 10, causing the piston plate 8 to move within the support arm 2, stretching the spring 9 to ensure clamping stability and buffering the clamping force. The servo motor 17 is started to drive the drive gear 18 to rotate. The drive gear 18 drives the support arm 2 to rotate through the gear ring 19. The support arm 2 drives the car anti-theft device to rotate through the L-shaped clamping plate 3, which can adjust the angle of the car anti-theft device.
