The boom clamping mechanism as described in claim 1, characterized in that, The movable seat is provided with a vertically extending first slide rail on the side facing the second clamping plate, and the second clamping plate is provided with a first slider that slides and engages with the first slide rail.

3. The boom clamping mechanism as described in any one of claims 1-2, characterized in that, The mounting base includes a support plate, a first mounting plate, and a second mounting plate. The first mounting plate and the second mounting plate are respectively connected to the upper and lower ends of the support plate. The first clamping plate is hinged to the end of the first mounting plate away from the support plate. The moving drive component is installed on the side of the support plate facing the moving seat. The second mounting plate is installed on the lifting frame, and the moving seat is slidably installed on the second mounting plate.

4. The boom clamping mechanism as described in claim 3, characterized in that, The first mounting plate is provided with a horizontally extending second slide rail, and the lower side of the movable seat is provided with a second slider that slides and engages with the second slide rail.

5. The boom clamping mechanism as described in claim 3, characterized in that, The clamping assembly further includes a push drive component and an adapter plate. The push drive component is mounted on the lifting frame and connected to one end of the adapter plate. The other end of the adapter plate is connected to the second mounting plate. The push drive component is used to drive the adapter plate to move the second mounting plate relative to the lifting frame. The lifting frame is provided with a horizontally extending third slide rail, and the lower side of the second mounting plate is provided with a third slider that slides and engages with the third slide rail.

6. The boom clamping mechanism as described in claim 3, characterized in that, The clamping assembly further includes a backstop hook, which includes an extension section, a connecting section, and a backstop section. The connecting section and the backstop section are both connected to the extension section, and the connecting section is connected to the first mounting plate. The backstop section is located at one end of the extension section near the second clamping plate and extends upward from the extension section. A backstop groove is formed between the backstop section and the extension section.

7. The boom clamping mechanism as described in any one of claims 1-2, characterized in that, The lifting frame includes a lifting plate and a support plate connected to the upper end of the lifting plate. The mounting base is installed on the support plate, and the lower side of the support plate is connected to the lifting drive component. A fourth slide rail extending vertically is provided on the side of the frame facing the lifting plate, and a fourth slider is provided on the lifting plate that slides in contact with the fourth slide rail.

8. A vehicle assembly production line, characterized in that, The vehicle assembly line includes a hoisting mechanism and a boom clamping mechanism as described in any one of claims 1-7. The boom clamping mechanism is installed on the workshop floor. The hoisting mechanism includes a hoisting drive, a guide rail, and a lifting device slidably installed on the guide rail. The guide rail is installed on the workshop ceiling. The hoisting drive is used to drive the lifting device to slide along the guide rail so that the lifting device moves closer to or away from the boom clamping mechanism.
