Abstract
A tool holder includes a main body having a bottom wall and a number of substantially L-shaped separation walls formed on the bottom wall, thereby defining a substantially L-shaped receiving compartment between each two adjacent separation walls. Each separation wall includes a first section and a second section. A resilient retaining member is mounted on the first section of each separation wall. Each receiving compartment includes a relatively longer section and a relatively shorter section. A guiding wall is extended across two second sections respectively of two adjacent separation walls. The guiding wall includes a downwardly extending guiding surface that faces the bottom wall. The downwardly extending guiding surface is preferably arcuate and inclines downwardly toward the bottom wall. The bottom wall includes a guiding surface section that is located below the downwardly extending guiding surface of the guiding wall and inclines downwardly along a direction parallel to the extending direction of the downwardly extending guiding surface of the guiding wall. The main body further includes a retaining wall provided to the relatively shorter section of each receiving compartmen…
