A mechanical joint system, comprising:
- a joint defining a pivot hole and a joint receiving hole communicating with the pivot hole;
- an arm being rotatable relative to the joint, the arm comprising a pivot portion and a pivot hole defined in the pivot portion, the pivot portion being received in the joint receiving hole;
- a plurality of teeth formed on an inner surface adjacent to an end of the pivot hole;
- and
- an engaging member comprising a pivot shaft, a fixing member, and at least one prong, the pivot shaft being fixed to the joint and comprising a shaft head and a shaft portion extending from an end of the shaft head, the shaft head being inserted into the pivot hole from an end thereof, the fixing member being inserted into the pivot hole from an opposite end thereof, and fixed relative to the pivot shaft;
- wherein the shaft portion defines a threaded hole in an end opposite to the shaft head and at least one groove communicating with the threaded hole thereby forming an elastic plate connecting to the shaft portion, and the prong extends from an outer surface of the elastic plate for engaging with the teeth.
