Abstract

Claims (45)

1. A handheld power tool comprising:

a housing including a front end, a rear end, a first side, and a second side;

a tool receptacle disposed on the front end of the housing, the tool receptacle configured to receive a tool;

a motor positioned within the housing and operatively coupled to the tool receptacle to drive the tool;

a handle disposed on the rear end of the housing;

a tube extending through at least a portion of the housing; and

an auxiliary handle selectively coupled to the housing, the auxiliary handle being at least partially insertable into the tube,

wherein the tube extends through an entire width of the power tool, and

wherein the auxiliary handle is selectively insertable into the tube from the first side of the housing and selectively insertable into the tube from the second side of the housing.

2. The handheld power tool of claim 1 , wherein the auxiliary handle is oriented orthogonal to the handle.

3. The handheld power tool of claim 1 , wherein the auxiliary handle is movable between an extended position and a collapsed position.

4. The handheld power tool of claim 3 , wherein the auxiliary handle is insertable into the tube at a first depth corresponding the extended position and is insertable into the tube at a second depth corresponding to the collapsed position.

5. The handheld power tool of claim 1 , wherein the auxiliary handle includes

a pin case insertable into the tube;

a grip supported on an end of the pin case;

a pin disposed within the pin case and axially slidable within the pin case between a locked position and an unlocked position;

a ball disposed within a ball aperture in the pin case, the ball being movable in a radial direction between a locked and an unlocked position; and

an actuator operable unlock the pin and ball.

6. The handheld power tool of claim 5 , wherein actuation of the actuator enables the pin case to slide relative to the tube.

7. The handheld power tool of claim 6 , further comprising a biasing member configured to bias the pin towards the locked position and limits movement of the pin case relative to the tube.

8. The handheld power tool of claim 1 , wherein the power tool further includes a dust collection assembly having a suction tube and a fan configured to generate airflow through the suction tube.

9. An auxiliary handle for a handheld power tool, the auxiliary handle comprising:

a tube extending through a portion of the handheld power tool;

a pin case insertable into the tube;

a grip supported on an end of the pin case; and

a locking mechanism configured to selectively lock the pin case relative to the tube, the locking mechanism including

a pin disposed within the pin case and axially slidable within the pin case between a locked and an unlocked position;

a ball disposed within a ball aperture in the pin case, the ball being movable in a radial direction between a locked and an unlocked position; and

an actuator operable unlock the pin and ball.

10. The auxiliary handle of claim 9 , wherein the locking mechanism further comprises a biasing member configured to automatically bias the pin and ball towards the locked position.

11. The auxiliary handle of claim 10 , wherein actuation of the actuator overcomes the biasing force of the biasing member to enable the pin case to move relative to the tube.

12. The auxiliary handle of claim 11 , wherein the actuator is positioned within a cavity in the grip, and wherein the actuator is configured to be depressed when actuated.

13. The auxiliary handle of claim 9 , the pin case is lockable in a first position relative to the tube corresponding to an extended position, and wherein the pin case is lockable in a second position relative to the tube corresponding to a collapsed position.

14. The auxiliary handle of claim 13 , wherein the tube includes a first receiving opening on a first end of the tube corresponding to the extended position, and wherein the tube includes a second receiving opening on a second end of the tube corresponding to the collapsed position.

15. The auxiliary handle of claim 9 , wherein the pin case is insertable into the tube from a righthand side, and wherein the pin case is selectively removable from the tube and insertable into the tube from a lefthand side.

16. A handheld power tool comprising:

a housing including a front end, a rear end, a first side, and a second side;

a tool receptacle disposed on the front end of the housing, the tool receptacle configured to receive a tool;

a motor positioned within the housing and operatively coupled to the tool receptacle to impart rotational movement on the tool receptacle;

a handle disposed on the read end of the housing;

a tube extending through at least a portion of the housing; and

an auxiliary handle insertable into the tube at a first depth corresponding to a collapsed position and insertable into the tube at a second depth corresponding to an extended position; the auxiliary handle selectively insertable into the tube from the first side of the housing and the second side of the housing.

17. The power tool of claim 16 , wherein the auxiliary handle includes a pommel handle.

18. The power tool of claim 16 , wherein the auxiliary handle includes a locking mechanism configured to lock the auxiliary handle relative to the tube.

19. The power tool of claim 18 , wherein the locking mechanism includes a pin case, a pin disposed within the pin case and axially slidable within the pin case between a locked and an unlocked position, and an actuator operable slide the pin between the locked and unlocked position.
