Abstract

A detachable combination tool includes a first body, a second body, two locking blocks, and an elastic member. Thus, the second body can be detached from the first body easily and conveniently, so that the second body and the first body can be used independently, thereby facilitating the user operating the combination tool. In addition, the detachable combination tool can withstand a larger torque or force during operation.

Claims

the first body has an inside formed with a receiving chamber;

the receiving chamber of the first body has two sides each formed with a snap recess;

the second body is detachably mounted on the first body and has a bottom provided with a protruding block received in the receiving chamber of the first body;

the protruding block of the second body has two sides each formed with a through hole aligning with the respective snap recess of the first body; and

each of the two locking blocks is movably mounted on the second body and has a bottom provided with a protruding locking portion extended through the respective through hole of the protruding block of the second body and detachably locked in the respective snap recess of the first body, so that the second body is detachably fixed to the first body by the two locking blocks.

2. The detachable combination tool in accordance with claim 1, wherein the first body has an end having two sides each formed with a pivot recess, and the detachable combination tool further comprises a control plate mounted on the first body and having two sides each provided with a pivot ear pivotally mounted in the pivot recess of the first body.

3. The detachable combination tool in accordance with claim 1, wherein the first body has a distal end formed with a pivot hole, and the detachable combination tool further comprises a first pivot rod pivotally mounted in the pivot hole of the first body, and a first tool secured on the first pivot rod to pivot therewith.

4. The detachable combination tool in accordance with claim 1, wherein the second body has a distal end formed with a pivot hole, and the detachable combination tool further comprises a second pivot rod pivotally mounted in the pivot hole of the second body, and a second tool secured on the second pivot rod to pivot therewith.

5. The detachable combination tool in accordance with claim 1, wherein the second body has two sides each formed with a press slot located above the respective through hole of the protruding block, and each of the two locking blocks is movably mounted in the respective press slot of the second body.

6. The detachable combination tool in accordance with claim 1, further comprising an elastic member mounted between the two locking blocks for pressing the two locking blocks toward the second body, so that the locking portion of each of the two locking blocks is pressed to be locked in the respective snap recess of the first body.
