Tapping tool structure

The present invention relates to a hand tool, and in particular to a tapping tool structure.

The tapping can quickly tap the perforation with internal thread, which is usually installed in the in-line operation handle or tapping machine, milling machine, lathe, etc. In use, the tapping must be placed in a hole having an inner diameter smaller than the outer diameter of the tapping and repeatedly twisted back and forth, thereby cutting the inner wall of the hole and removing the chips to form a screw hole.

However, since the force control of the user cannot be finely adjusted as mechanically controlled, the smaller the outer diameter of the screw can withstand the critical torque, so when the screw tap is used in the in-line operating handle, the screw At the end of the attack, the user often breaks due to excessive and uneven force applied during the reciprocating torsion operation. The broken part is usually stuck in the hole being processed, and the screw hole is still at this time. It has not been completed yet, but the screw tap has been broken and inserted into the hole for a short period of time, which cannot be pulled out, causing great trouble to the user. In particular, in the case of manufacturing a screw hole having a smaller hole diameter, that is, a screw having a smaller outer diameter, it is more likely that a tapping break occurs due to a small force deviation when the user twists.

Therefore, in one aspect of the present invention, a tapping tool structure is provided, and the grip structure has a buffer portion for allowing the user to absorb the torque when the user twists by the buffer portion, and gradually release the torque to the connection. The tapping of the screw makes the force of the tapping attack average and gradual. Therefore, even if the user applies the grip with uneven or excessive force, the screw tapping and breaking of the connection is not easy to achieve the best use effect.
