Description
Technical Field
The invention belongs to the technical field of hardware tools, and particularly relates to a self-tapping intelligent clamp holder matched with an electric wrench to enable a hand to be tapped.
Background
A common screw needs to be provided with a processed screw hole to be screwed in. Self-tapping, as the name suggests, can be a self-tapping screw that is self-tapped while being threaded in, and is commonly used for steel structural joining (e.g., joining and securing two lengths of steel tubing). A common self-tapping (fig. 1) is a drill bit at one end, a wrenching structure (typically a nut) at the other end, and a screw in the middle. Because the self-tapping is screwed in and needs certain speed, so the electric spanner is commonly used for screwing in the self-tapping, when the electric spanner is used for screwing in the self-tapping, the self-tapping drill bit is in an unfixed state, and the self-tapping drill bit is difficult to enter a steel structure, the self-tapping deviation phenomenon and the self-tapping phenomenon frequently occur, and the tapping success rate is lower. To solve this problem, it seems simple and difficult to do, because screwing in the self-tapping is different from nailing, the nailing is performed by clamping with pliers, if the self-tapping is also performed by clamping with pliers, the threads on the self-tapping are destroyed, the fixed connection effect is not achieved, and in addition, the self-tapping is in a fast rotation state, and the self-tapping cannot be directly clamped by hand, so that the problem is very dangerous.
