Abstract
A reciprocating cutting tool includes a blade attachment to which a blade is detachably attachable. The blade attachment is reciprocable. The blade attachment includes a first pressing member movable toward or away from the blade to press the blade, a first urging member that urges the first pressing member, a second pressing member that can press the blade in a direction different from a direction in which the first pressing member presses the blade, and a second urging member that urges the second pressing member. The first pressing member automatically presses the blade when the second pressing member is pushed by the blade. The first urging member is located to avoid being in a moving direction of the first pressing member.
Claims20
A reciprocating cutting tool, comprising:
- a blade attachment to which a blade is detachably attachable, the blade attachment being reciprocable, the blade attachment including
- a first pressing member movable toward or away from the blade to press the blade,
- a first urging member configured to urge the first pressing member,
- a second pressing member configured to press the blade in a direction different from a direction in which the first pressing member presses the blade, and
- a second urging member configured to urge the second pressing member,
- wherein the first pressing member automatically presses the blade when the second pressing member is pushed by the blade, and
- the first urging member is located to avoid being in a moving direction of the first pressing member.
A reciprocating cutting tool, comprising:
- a blade attachment to which a blade is detachably attachable, the blade attachment being reciprocable, the blade attachment including
- a sleeve rotatable about a direction in which the blade attachment is reciprocable, the sleeve including a receiving portion,
- a first pressing member located radially inward from the sleeve and movable in response to rotation of the sleeve, the first pressing member being movable toward or away from the blade to press the blade,
- a first urging member located radially inward from the sleeve, the first urging member being configured to urge the first pressing member,
- a second pressing member configured to press the blade in the direction in which the blade attachment is reciprocable, the second pressing member including
- an engaging portion engageable with the receiving portion to stop rotation of the sleeve,
- a pressing portion extending in the direction in which the blade attachment is reciprocable, and
- a tongue integrally connecting the engaging portion and the pressing portion and extending in the direction in which the blade attachment is reciprocable, the tongue being offset from an imaginary centerline of the pressing portion in a direction perpendicular to the direction in which the blade attachment is reciprocable, and
- a second urging member configured to urge the second pressing member,
- wherein, when the pressing portion is pushed by the blade, the engaging portion moves out of the receiving portion.
