The rack and the gear can effectively convert the linear movement of the Y-axis moving module and the Z-axis lifting module into the rotation of the gear, and the data fed back by the encoder 7 can also constitute the coordinates of the screw hole position.

[0032] Working principle: the workpiece needing screwing operation can be fixedly placed below the straight intersection high-precision manual screwing mechanism, and a plane coordinate system in X-axis direction and Y-axis direction can be established according to the moving direction of the Y-axis moving module and the Z-axis lifting module, when the operator moves the Y-axis moving module along the X-axis direction, the first transmission wheel 5 on the Y-axis moving module will rotate along the fixed axis due to the transmission relationship between the first transmission wheel 5 and the first transmission element 3, and the encoder 7 connected with the first transmission wheel 5 through the transmission shaft will rotate synchronously. Similarly, when the operator moves the Z-axis lifting module along the Y-axis direction, the corresponding encoder 7 can rotate synchronously with the second transmission wheel 6, and the data feedback by the two encoders 7 can be combined to accurately position each coordinate position needing screwing and make reasonable order.
