Description

Electric drill work holding device

The utility model provides a working object holding device for an electric drill, in particular to a technical field in which an electric drill is convenient for holding a work object and maintaining drilling stability and drilling precision.

Generally, the portable electric drill is used for the drilling of outdoor or large workpieces. Because the drilling workpiece is made of metal material, the drill bit is difficult to locate during drilling, and the drilling position is often displaced, causing the drilled hole to be inclined. The hole, or the phenomenon of reaming, is actually difficult to use. For this reason, the creator of this case developed the patent No. 83210588, "Working device for holding portable electric drill". The patent case has practical value. Therefore, the promotion in the city is widely praised by consumers.

However, the creator is not complacent. After reviewing the structure of the patent, the fixed tongue on the end face of the fixed frame is locked and fixed with the threaded hole of the portable electric drill. Therefore, the electric drill is relatively suitable. The range is relatively narrow, and the combination of each fixed baffle and the fixed frame is fixed, and the welding method is adopted. In order to achieve the precision required for the operation, it is necessary to repeatedly perform the measurement operation, thereby reducing the production efficiency, etc. Missing.

In view of this, the creator has actively worked hard to study, and after many trials and improvements, finally developed a new type of practical effect.
