Detailed Description

The invention will be further elucidated with reference to the drawings and the embodiments, which are exemplary only and do not limit the scope of the invention.

As shown in fig. 1 and 2, a multifunctional tool holder comprises a body 1, a collet 2 and a tool bit 3, wherein the tool bit 3 is mounted on the body 1 through the collet 2; a knife flywheel 4 is also arranged on the outer side wall of the body 1. The utility model discloses an add a break bar 4 on body 1, thereby let the utility model discloses a multi-functional sword handle can have two cutters of tool bit 3 and break bar 4, has realized the manifold effect of function. In the use, after the tool bit 3 is used for drilling and other operations, the cutter wheel 4 can be directly used for grinding, so that the tool does not need to be replaced by a worker, the use is greatly facilitated, and the practicability is high.

Wherein, the knife flywheel 4 is sleeved on the body 1, and the knife flywheel 4 is locked on the body 1 through a knife flywheel cap 5. Preferably, the cutter wheel cap 5 is a nut. The knife flywheel 4 can be widely assembled and disassembled through the arrangement.

The outer side wall of the body 1 is provided with a step 11, the upper end face of the cutter wheel 4 is tightly abutted against the step 1, and the cutter wheel cap 5 is in threaded connection with the lower end of the body 1 and the upper end of the cutter wheel cap 5 is tightly abutted against the lower end face of the cutter wheel 4. The cutter wheel 4 can be stably fixed by the above arrangement.

The collet 2 employs a multi-lobed clamping arrangement slotted in the axial direction. Preferably, the collet 2 is arranged in the body 1, the collet 2 and the body 1 are in taper fit, and specifically, the lower end of the collet 2 and the lower end of the body 1 are both provided with corresponding matched taper structures; the upper end of the cutter head 3 is arranged in the collet 2, and the lower end of the cutter head 3 extends out of the body 1. Since the collet 2 is prior art, it will not be described in detail here.

A central hole 12 penetrating through two ends of the body 1 is arranged in the body 1, the collet chuck 2 is arranged in the central hole 12, and more specifically, the lower end of the central hole 12 is a conical structure corresponding to the lower end of the collet chuck 2; a tool bit locking screw 6 is also arranged in the central hole 12; the lower end of the tool bit locking screw 6 is in threaded connection with the collet chuck 2.
