A tool connector, comprising:
- a main body, including a driving end and a connecting end which are disposed opposite to one another in an axial direction of the tool connector, the driving end configured to be connected with a driving tool, the main body having a first receiving hole extending lengthwise from the connecting end toward the driving end in the axial direction and a second receiving hole communicated with the first receiving hole, a diametrical dimension of the first receiving hole being larger than a diametrical dimension of the second receiving hole, the second receiving hole extending lengthwise in the axial direction, and a side of the main body adjacent the connecting end having a first radial hole extending in a direction lateral to the axial direction and communicated with the first receiving hole;
- an adapter, non-rotatably disposed within the first receiving hole, the adapter including a through hole configured for a tool bit to be disposed therethrough, and the adapter further configured to have a hole saw mounted thereon;
- a first engager, movably received within the first radial hole;
- a pushing member;
- a first elastic member;
- and
- a sleeve, sleeved to the main body and being movable between a lock position and a release position;
- wherein when the sleeve is in the lock position, the sleeve urges the first engager to radially protrude into the first receiving hole and be engaged with the adapter;
- and when the sleeve is in the release position, the first engager is radially retracted and the adapter is detachable from the first receiving hole;
- wherein the first receiving hole has a first cross-sectional profile that is non-circular, the second receiving hole has a second cross-sectional profile that is non-circular, and the through hole has a third cross-sectional profile that is non-circular, the second cross-sectional profile and the third cross-sectional profile are identical in shape and are coaxially arranged, and as viewed in the axial direction, at least one geometric feature of the second cross-sectional profile corresponds to at least one geometric feature of the third cross-sectional profile,
- wherein the pushing member and the first elastic member are located between the main body and the adapter with respect to the axial direction, and
- wherein an outer profile of the pushing member is non-circular, the pushing member is received in the first receiving hole and is movable relative to the main body in the axial direction, and wherein the first elastic member is elastically abutted against and between the pushing member and the main body so that the pushing member is biased toward the adapter.
