[0002] Buildings refer to civil and public buildings with historical significance before the founding of the People's Republic of China. Currently, many ancient towns and most large cities still retain some ancient buildings. Currently, the restoration of ancient buildings requires the use of specific wood restoration workbenches.

[0003] When the wood repair workbench in the prior art is used, the wood is generally placed on the workbench, and two clamping tools are used to clamp and fix the wood to prevent the wood from shifting during repair. However, when the wood is actually repaired, sometimes multiple parts of the wood need to be repaired. Since the wood has been clamped and fixed, the worker needs to hold the repair tool and walk to the vicinity of the part of the wood to be repaired. The wood repair work is complicated and tiring. Frequent walking makes the workers more tired. The fatigue of the workers further affects the wood repair work and reduces the efficiency of wood repair. Utility Model Content
