ットホルダーは、ビットが固定せず、ホルダーとの隙間
によりふらついて使用しにくいという問題もある。However, in the bit holder in which the conventional bit locking ring 26 is fitted in the bit fitting hole 24, the bit is held by the resistance of the locking ring 26. Therefore, there is a problem in durability because the holding force is weak and the bit easily comes off, and this type of bit holder also has a problem in that the bit is not fixed and the gap between the bit holder makes it unstable and difficult to use.

ビットホルダーを提供するにある。The present invention has been made in view of the above-mentioned circumstances, and the purpose thereof is to constantly press the spring of the bit to provide a strong holding force and a fixed stopping method. An object of the present invention is to provide a bit holder that is easy to insert and remove and has great durability.

る。In order to achieve the above object, the present invention takes the following technical means. That is, according to the present invention, the rotary tool mounting member is provided on one end side in the axial direction of the bit holder body, and the bit fitting hole is provided on the other end side.
In a bit holder in which a magnet is fitted inside the bit fitting hole, a linear spring fitting cutout hole that opens on the inlet side peripheral surface of the bit fitting hole is inclined from the outside of the bit holder body toward the tip center. A bit holding part formed at the bit inlet side end of the bit holding linear spring wound in a coil shape around the outer periphery of the bit holder body in the radial direction in the linear spring fitting cutout hole. It is characterized in that it is fitted so as to be movable diagonally and is inserted into the bit fitting hole.

ばねのビット押圧保持力が増大し、ビットを強力に保持
するため、ビットがガタつかず安定する。According to the present invention, when the bit is inserted into the bit fitting hole of the bit holder, the bit holding portion at the bit inlet side end of the linear spring is pushed outward in the radial direction to press the bit of the spring. The holding force is increased and the bit is strongly held, so the bit is stable without rattling.

き出すことができ、簡単な操作でビットを交換できる。Therefore, when the tip of the head of the bit bites into the head of a screw or the like, when the bit holder is pulled, the bit inlet side end of the spring causes the inclined surface of the linear spring fitting cutout hole of the holder body. It is pushed by and moves toward the axis center of the holder main body, and enters into a state of biting between the bit and the inclined surface, and the bit is firmly clamped and held. When pulling out the bit from the bit holder, the elastic force of the spring is weakened by slightly retracting the bit inlet side end of the linear spring toward the rotary tool, and the bit can be easily pulled out from the fitting hole. You can change the bit with a simple operation.

部6Aが係止され、保持状態になる。When the force for moving the spring cover 7 rearward is released, the cover 7 is pushed back by the elastic force of the linear spring 6 and the bit holding portion 6A returns to its original position (FIG. 6). Is indicated by a two-dot chain line 61). In the above embodiment, the bit 13 is replaced with the bit fitting hole 9 of the bit holder main body 2.
, The bit holding portion 6A of the linear spring 6 is pushed from the position of the chain double-dashed line 61 to the position of the solid line in the direction of arrow A against the elastic force of the spring 6, as shown in FIG. Moved, bit 13
In a state where the tapered surface 15 of the bit is fitted into the tapered hole 14 of the bit support 5, the bit holding portion 6A is locked in the cutout portion 16 of the bit 13 and becomes in the holding state.

力が増大してビット13が抜け出すことはない。In this way, when the bit 13 is fitted in the bit holder 1, it is sufficient to insert the bit 13 without operating the spring cover 7, and the tip 13A of the tip of the bit 13 is the screw head. When bit holder 1 is pulled in the direction of arrow C in the figure when it bites into a cross groove, etc., the elastic force of spring 6 causes bit holding part 6A to bite between the slope of cut hole 12 and bit 13 by bit 13. The bit holding force does not increase and the bit 13 does not come out.

ものも利用できる。When the bit 13 is extracted and replaced, the spring cover 7 is pulled in the direction shown by the arrow C in FIG. 1 so that the front end inward flange 7A of the spring cover 7 causes the bit releasing operation portion 6C to move to the position shown in FIG. Also, since the bit holding force is released by pushing in the direction indicated by the arrow A in FIG. 6, the bit 13 can be easily pulled out. The present invention is not limited to the above-described embodiment. For example, the spring cover 7 can be omitted, and the present invention can be applied to a bit holder that is not provided with the bit support 5. The one without the notch 16 can also be used.
