Power tool attachment
A power tool attachment is configured to connect to a power tool at a static interface and a dynamic interface. The static interface statically fixes the power tool and power tool attachment together. The dynamic interface provides rotational motion generated by the power tool to the power tool attachment. The rotational motion is provided to a drive of the power tool attachment that converts the rotational motion to a linear reciprocating output.
1. A power tool appliance for use with a power tool that outputs rotational motion for one or both of drilling and fastening, the power tool appliance configured to attached to, and receive rotational input from, the power tool, the power tool appliance comprising:
a housing;
a drive at least partially located within the housing, the drive comprising an input shaft having an end that is configured to be received by the power tool, the drive converting rotational motion received from the power tool through the input shaft into a reciprocating motion; and
a support connected to the housing, the support configured to interface with the power tool to statically connect the power tool to the housing, the support comprising an arm that extends away from the housing and that connects between the power tool and the housing;
wherein the support comprises a plate on which a battery portion of the power tool stands and a strap that extends around at least part of the plate, wherein the strap wraps at least partially around the battery portion of the power tool to brace the power tool relative to the housing and hold the battery portion of the power tool against the plate.
2. The power tool appliance of claim 1 , wherein the strap includes hook and loop fasteners.
3. The power tool appliance of claim 2 , wherein the arm pivots relative to the housing.
4. The power tool appliance of claim 1 , wherein the end of the input shaft is multi-faceted.
5. The power tool appliance of claim 1 , wherein material that forms the input shaft is contiguous with material that forms at least part of an eccentric of the drive.
6. A power tool appliance for use with a power tool that outputs rotational motion for one or both of drilling and fastening, the power tool appliance configured to attached to, and receive rotational input from, the power tool, the power tool appliance comprising:
a housing;
a drive at least partially located within the housing, the drive comprising an input shaft having an end that is configured to be received by the power tool, the drive converting rotational motion received from the power tool through the input shaft into a reciprocating motion; and
a support connected to the housing, the support configured to interface with the power tool to statically connect the power tool to the housing, the support comprising an arm that extends away from the housing and that connects between the power tool and the housing;
wherein the arm is biased by at least one spring to urge the power tool relative to the housing.
7. The power tool appliance of claim 6 , wherein the at least one spring urges the arm to shorten which, due to the power tool being connected to the housing via the arm of the support, urges the power tool relative to the housing.
8. The power tool appliance of claim 7 , wherein one or more spring of the at least one spring is located inside of the arm, the arm comprises telescoping parts to shorten and lengthen the arm, and the one or more spring of the at least one spring urges the arm to shorten or lengthen.
9. The power tool appliance of claim 6 , wherein one or more spring of the at least one spring is located outside of the arm and urges a strut of the power tool appliance.
10. The power tool appliance of claim 9 , wherein the strut engages the arm which, due to the power tool being connected to the housing via the arm of the support, urges the power tool relative to the housing.
11. The power tool appliance of claim 9 , wherein the one or more spring of the at least one spring is located between the housing and the strut such that the one or more spring pushes the strut away from the housing.
12. The power tool appliance of claim 6 , wherein the at least one spring urges the power tool to pre-load the power tool to minimize entry into a mode of the power tool.
13. The power tool appliance of claim 6 , wherein the at least one spring urges the power tool to align relative to the housing of the power tool appliance.
14. A power tool appliance for use with a power tool that outputs rotational motion for one or both of drilling and fastening, the power tool appliance configured to attached to, and receive rotational input from, the power tool, the power tool appliance comprising:
a housing;
a drive at least partially located within the housing, the drive comprising an input shaft having an end that is configured to be received by the power tool, the drive converting rotational motion received from the power tool through the input shaft into a reciprocating motion; and
a support connected to the housing, the support configured to interface with the power tool to statically connect the power tool to the housing, the support comprising an arm that extends away from the housing and that connects between the power tool and the housing;
wherein the support comprises a plate on which the battery portion of the power tool stands, and wherein the plate is connected to the arm by a hinge which permits the plate to pivot relative to the arm.
15. The power tool appliance of claim 14 , further comprising a pump that receives the reciprocating motion from the drive which operates the pump.
16. The power tool appliance of claim 15 , further comprising a spray nozzle that sprays fluid output by the pump and a reservoir supported by the housing, the pump in fluid communication with the reservoir.
