         9 . The ETJDT of  claim 7 , wherein the at least one first component is configured to retract in response to fluid pressure in the chamber exceeding a threshold pressure, wherein the fluid pressure is configured to drive the at least one first component into a second spring and compress the second spring in response to the fluid pressure in the chamber exceeding the threshold pressure. 
     
     
         10 . The ETJDT of  claim 1 , further comprising a flow restrictor or a pressure-drop device, wherein the flow restrictor or pressure-drop device is disposed at a distal end of the tool body. 
     
     
         11 . The ETJDT of  claim 1 , wherein the first spring is configured to bias the movable member in an uphole direction, and wherein the first spring is in an uncompressed state to bias the movable member to move in an uphole direction in response to fluid pressure in the central bore being below a threshold pressure.  
     
     
         12 . The ETJDT of  claim 11 , wherein the at least one second component is configured to retract in response to movement of the movable member in the uphole direction, and wherein the at least one second component is configured to extend in response to movement of the movable member in a downhole direction. 
     
     
         13 . The ETJDT of  claim 1 , wherein the movable member has ramps formed at a distal end of the movable member, wherein the ramps taper radially inward in a downhole direction, wherein the at least one second component is slidably secured to the ramps of the movable member such that axial movement of the movable member is configured to extend or retract the at least one second component.  
     
     
         14 . The ETJDT of  claim 1 , wherein the at least one first component includes a first dog disposed in a first section of the tool body, and wherein the first dog includes a first fluid-actuated member. 
     
     
         15 . The ETJDT of  claim 14 , wherein the at least one second component includes a second dog disposed in a second section of the tool body, and wherein the second dog is smaller than the first dog.
