【発明が解決しようとする課題】ラチェットの動作方向
切り替えの不便をなくすることを目的とする。SUMMARY OF THE INVENTION An object of the present invention is to eliminate the inconvenience of switching the operation direction of the ratchet.

ルクを伝える方法として、摩擦クラッチあるいは歯つき
クラッチを使用する。このクラッチは常時は開放されて
いて、接続時にはねじの締め緩め両方向のトルクを伝達
することが出来る。As a method of transmitting torque from the grip portion to the bit shaft, a friction clutch or a toothed clutch is used. This clutch is always open, and when connected, can tighten and loosen the screws to transmit torque in both directions.

ける力を利用してクラッチを接続すれば、自然な使用状
態でクラッチの接続が行われることになる。When a large torque is required to tighten and loosen a screw, it is necessary to simultaneously press the bit against the screw thread with a force corresponding to the torque. If the clutch is connected using the pressing force, the clutch is connected in a natural use state.

ことによって高速に締め緩め作業が可能となる。When turning the screw with a small torque, it is not necessary to strongly press the bit against the screw head, the clutch is released by the spring, and the bit shaft can freely rotate with respect to the grip. By turning the bit shaft or the thin knob in this state, the tightening and loosening operation can be performed at high speed.

れる。DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. The bit shaft 3 is attached to the grip portion 1 via a bearing 8 so as to be freely rotatable and freely movable in the axial direction. A clutch 7 is arranged between the grip 6 and the flange 6 fixed to the bit shaft 3. Normally, the clutch 7 is released by the clutch release spring 2. When a large torque is required, the clutch 7 is connected by pushing the grip 1 in the direction of the bit 4, and the torque from the grip 1 is transmitted to the bit shaft 3.

先端方向に押す力を利用するため、特にクラッチ接続の
ための操作を必要としない。According to the present invention, the rotational connection between the grip portion and the bit shaft is performed by the clutch, so that the direction switching such as a ratchet is not required. Since the force for pushing the grip portion toward the tip of the bit is used for connecting the clutch, an operation for connecting the clutch is not particularly required.
