A manual tool having a retractable tool member, further comprising a handle and a linkage member, wherein the handle comprises a first handle portion and a second handle portion, the first handle portion having a first proximal end and a first distal end, the second handle portion having a second proximal end and a second distal end, the first handle portion being rotatable about a first pivot located at the first proximal end, the second handle portion being rotatable about a second pivot located at the second proximal end, and the first pivot and the second pivot being connected through a connector; the linkage member comprises a first linkage member and a second linkage member, the first linkage member having a first tool end and a first handle end, and the second linkage member having a second tool end and a second handle end; the tool member (5, 5A, 5B) has a third pivot and a fourth pivot, the first linkage member being rotatably connected with the tool member (5, 5A, 5B) through the third pivot at the first tool end, and the second linkage member being rotatably connected with the tool member (5, 5A, 5B) through the fourth pivot at the second tool end; a fifth pivot is provided between the first proximal end and the first distal end of the first handle portion, the first linkage member being rotatably connected with the first handle portion through the fifth pivot at the first handle end, and a sixth pivot is provided between the second proximal end and the second distal end of the second handle portion, the second linkage member being rotatably connected with the second handle portion through the sixth pivot at the second handle end; and the tool member (5, 5A, 5B) is configured to be retractably movable relative to the handle between an operating state and a retracting state under the driving of the handle and the linkage member; characterized in that: when the tool member (5, 5A, 5B) is in the operating state, the tool member (5, 5A, 5B) is deployed beyond the first proximal end and second proximal end; and when the tool member (5, 5A, 5B) is in the retracting state, the tool member (5, 5A, 5B) is retracted to a position between the first proximal end and the second proximal end and between the first distal end and the second distal end; wherein the first handle portion, the second handle portion, the first linkage member, the second linkage member and the tool member (5, 5A, 5B) constitute a planar link system so that the tool member (5, 5A, 5B) retractably move, through the first linkage member and the second linkage member, with opening and closing movements of the first handle portion and the second handle portion. the handle comprises a first handle portion and a second handle portion, the first handle portion having a first proximal end and a first distal end, the second handle portion having a second proximal end and a second distal end, the first handle portion being rotatable about a first pivot located at the first proximal end, the second handle portion being rotatable about a second pivot located at the second proximal end, and the first pivot and the second pivot being connected through a connector; the linkage member comprises a first linkage member and a second linkage member, the first linkage member having a first tool end and a first handle end, and the second linkage member having a second tool end and a second handle end; the tool member (5, 5A, 5B) has a third pivot and a fourth pivot, the first linkage member being rotatably connected with the tool member (5, 5A, 5B) through the third pivot at the first tool end, and the second linkage member being rotatably connected with the tool member (5, 5A, 5B) through the fourth pivot at the second tool end; a fifth pivot is provided between the first proximal end and the first distal end of the first handle portion, the first linkage member being rotatably connected with the first handle portion through the fifth pivot at the first handle end, and a sixth pivot is provided between the second proximal end and the second distal end of the second handle portion, the second linkage member being rotatably connected with the second handle portion through the sixth pivot at the second handle end; and the tool member (5, 5A, 5B) is configured to be retractably movable relative to the handle between an operating state and a retracting state under the driving of the handle and the linkage member; characterized in that: when the tool member (5, 5A, 5B) is in the operating state, the tool member (5, 5A, 5B) is deployed beyond the first proximal end and second proximal end; and when the tool member (5, 5A, 5B) is in the retracting state, the tool member (5, 5A, 5B) is retracted to a position between the first proximal end and the second proximal end and between the first distal end and the second distal end; wherein the first handle portion, the second handle portion, the first linkage member, the second linkage member and the tool member (5, 5A, 5B) constitute a planar link system so that the tool member (5, 5A, 5B) retractably move, through the first linkage member and the second linkage member, with opening and closing movements of the first handle portion and the second handle portion.
