Abstract

A chain tool includes a body having a driving hole, a stop portion, and a receiving portion located between the driving hole and the stop portion in an axial direction. A pressing member is received in the receiving portion and is movable relative to the body in the axial direction. A push member is in threading connection with the first threaded portion and is movable relative to the body between a first position distant to the stop portion and a second position adjacent to the stop portion. The pressing member is pressed by the push member and moves in an arcuate path when the push member moves between the first and second positions.

First claim

The invention claimed is:

1. A chain tool comprising:
a body including a receiving portion, a driving hole, a stop portion, and a back board, wherein the receiving portion is located between the driving hole and the stop portion in an axial direction of the driving hole, wherein the driving hole includes an end intercommunicating with the receiving portion and a first threaded portion therein; and
a push unit including a pressing member and a push member, wherein the pressing member is received in the receiving portion and is movable relative to the body in the axial direction, wherein the push member includes a second threaded portion in threading connection with the first threaded portion, wherein the push member is movable between a first position and a second position relative to the body in the axial direction, wherein the push member presses against the pressing member to push the pressing member to move together with the push member, wherein the pressing member moves in an arcuate path when the push member moves between the first and second positions, wherein the pressing member is in a position distant to the stop portion when the push member is in the first position, wherein the pressing member is in a position adjacent to the stop portion when the push member is in the second position,
wherein a pivotal axis passes through an end of a rocker arm opposite to the pressing member, and wherein a fastener extends through a hole in the end of the rocker arm and is in threading connection with the back board.

2. The chain tool as claimed in claim 1 , wherein the receiving portion, the driving hole, and the stop portion are on a same side of the back board, wherein the pressing member includes the rocker arm pivotably connected to the back board about the pivotal axis perpendicular to the back board.

3. The chain tool as claimed in claim 1 , comprising:
wherein the back board includes a side facing the receiving portion and having a groove, wherein an elastic element is received in the groove and is a substantially V-shaped plate.

4. The chain tool as claimed in claim 3 , wherein the elastic element includes a first end attached to the back board and a second end abutting against a side of the pressing member opposite to the push member.

5. A chain tool comprising:
a body including a receiving portion, a driving hole, a stop portion, and a back board, wherein the receiving portion is located between the driving hole and the stop portion in an axial direction of the driving hole, wherein the driving hole includes an end intercommunicating with the receiving portion and a first threaded portion therein, wherein the receiving portion, the driving hole, and the stop portion are on a same side of the back board; and
a push unit including a pressing member and a push member, wherein the pressing member is received in the receiving portion and is movable relative to the body in the axial direction, wherein the push member includes a second threaded portion in threading connection with the first threaded portion, wherein the push member is movable between a first position and a second position relative to the body in the axial direction, wherein the push member presses against the pressing member to push the pressing member to move together with the push member, wherein the pressing member moves in an arcuate path when the push member moves between the first and second positions, wherein the pressing member is in a position distant to the stop portion when the push member is in the first position, wherein the pressing member is in a position adjacent to the stop portion when the push member is in the second position, wherein the pressing member includes a sliding seat, wherein the sliding seat is slidably disposed on the back board and is movable relative to the body along the arcuate path,
wherein the back board includes a side facing the receiving portion and having a sliding groove, wherein the sliding seat is disposed in the sliding groove, wherein the sliding groove and the sliding seat are arcuate, and wherein the pressing member protrudes beyond the sliding groove.

6. The chain tool as claimed in claim 5 , wherein the sliding groove includes a positioning protrusion protruding from a wall thereof and receives an elastic element, wherein the sliding seat has a slot, wherein the positioning protrusion and the elastic element are received in the slot, and wherein the elastic element includes a first end abutting against the positioning protrusion and a second end abutting against an inner wall of the slot adjacent to the push member.

7. The chain tool as claimed in claim 6 , wherein a cover is disposed on the body, covers the sliding groove, and is located on a side of the sliding seat opposite to the back board, and wherein a fastener extends through the cover and is in threading connection with the positioning protrusion.
