I.e., the design limits the right point so that the blade will not strike the workpiece is still in danger of forgetting screwing screws into account. [Summary of the Invention] 1265836 Applicant's pre-suggested fine-tuning boring tool is designed with a hard screw-solid design due to the combination of the shank and the tool holder shaft. The screw is used to force the screw to be solid, without anti-shock and anti-loose design, and when the user is flipping When the hole size is not locked and the lion is rotated, it will cause the blade to stop rotating after contacting the JL piece, resulting in a fine adjustment of the tool holder shaft, causing the blade to collide with the workpiece and cracking. The invention provides a micro-claw hole cutter 'main _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Depending on the needs of the working environment, the eccentric shaft hole is accommodated by a socket shaft of a front arbor, and the v-shaped ring groove provided on the socket shaft and the locking screw hole of the arbor body are radially disposed. Corresponding to positioning hungry, and by means of (4) force fixing bolt, the front arbor is pushed upwards to be close to the shank body, no gap is generated, and the front knives are locked by the locking screw and the positioning bolt with the arc end face. The rod enables the front arbor and the shank body to be stably stabilized in the axial direction and the radial direction, and the shank is rotated by the eccentric rod, so that the tip of the blade and the center of rotation can be slightly changed. The distance, the purpose of achieving the pupil size of 5 weeks, can be permanently positioned by the axis of the axis, which does not change with the fine adjustment of the pupil size. ^Gab can be used to change the micro-offset of the tip and the center of the cymbal by using a small amount of eccentric _ hole, and the knives can be used to create a hole in the hole of the fixed hole size. The fixed locking system of the rod-stacking system and the fixed-fixing of the dance force enable the front arbor to be fixed by the elastic force and face up, with the fixed inspection locking, to achieve the effect of completely rigid locking-body; 1265836 The externally fixed shaft hole makes the boring knife's and dynamic balance 〃 constant, and the rotary arbor does not change: The balance value is changed. Therefore, the fine adjustment of the boring size does not need to reset the dynamic balance. Practicality: Excellent The operation of reducing the boring operation; and the design of the limit gear in the shank body, even if the front arbor is not locked and the machine is rotated, the front shank is rotated to the minimum boring position position to avoid the blade hitting the aperture. Without the impact of the knife, the blade shaft is unlocked and the blade can be protected safely.
