[0002] During municipal road construction, it is often necessary to dig deep roadbed pits for operations. After the excavation of the foundation pit is completed, it is often necessary to set up a reinforcing support structure in the foundation pit. The support structure enhances the stability of the foundation pit, thereby improving the reliability of subsequent road construction processes and the safety of construction workers.

[0003] At present, most of the support devices, when in use, mostly use screws and telescopic cylinders to adjust and support the protection angle of the support device, so that the device and the side wall of the foundation pit of the roadbed fit together. Since the screws and telescopic cylinders on the support device are fixedly connected to the device, the actual cost of using the support device is too high. In addition, most of the existing support devices directly press the stressed side plates against the side walls of the foundation pit, resulting in greater pressure on the device from the side walls of the foundation pit, which shortens the service life of the support device.
