The main parts of the unlatching tool are upper joint, cylinder, spring, slider and lower joint. The upper end of the upper joint is connected with the tool string, and the lower thread is connected with the cylinder. The lower joint can move up and down in the spiral groove at the lower end of the cylinder under the action of the cylindrical pin of the spring machine, and finally the downhole tool can be dropped. The spring and slider can only release the lower joint.
