[0034] Working principle: The present embodiment provides a jacking manual rotating table. When an employee performs manual operation, the hand can hold the hand-held ball block 309 at the top of the adjusting assembly 3, and then pull it to make a rotating motion, which can drive the adjusting rod 301 under the circular plate 302 to rotate. Thereby, the gear 104 rotatably installed in the installation box 103 can be controlled to rotate, so that the meshing toothed ring 202 rotates synchronously, so as to achieve the effect of controlling the rotation of the circular table 2. During the rotation process, the number of rotation circles of the gear 104 can be controlled according to the angle to be rotated. At the same time, during the rotation process, the positioning strip 306 at the bottom of the circular plate 302 can move up and down under the limitation of the positioning groove 502 on the positioning disc 5. When the specified rotation angle is reached, the positioning strip 306 can be fitted with the positioning groove 502 at the corresponding position, so as to achieve the positioning effect, reduce the steps of operation fine-tuning, make the manual rotation of the circular table 2 more convenient, reduce the fatigue of the employee's operation, and maintain a good manual control adjustment speed.
