Referring to FIG. 4 and FIG. 5, when the space is used, the overall swing mode is adopted. At this time, the head 3 and the switching assembly 6 are rigidly connected with the grip portion 2, thereby having a high torque effect. It is worth noting that because the center of rotation of the grip 2 is located at the first pivot point 314, the knob The center of rotation of the 61 is located at the second pivot point 315, which causes an interference between the two, so that the grip 2 does not come off the knob 61 when the grip 2 is rotated. It is used in the same manner as a general ratchet wrench. First, the pocket 34 of the head 3 is sleeved and engaged with a fastener (not shown), such as a nut, and then applied to the grip 2 and Rotate clockwise to drive the nut to rotate. On the other hand, when the grip portion 2 is rotated in the counterclockwise direction, the grip portion 5 is idling with respect to the transmission unit 4, so that the nut is not rotated.

Referring to FIG. 8, when the overall swing mode is adopted, the grip portion 2 can only swing at a small angle, which is a waste of time. However, if the switching assembly 6 is turned to the local swing mode, refer to FIG. At this time, the grip portion 2 can swing at a large angle with respect to the head portion 3, and therefore, time can be greatly saved. The operation mode is that the head 3 is penetrated into a narrow space, and the head 3 is sleeved on the nut in the narrow space, and then the force is applied to the grip portion 2 and rotated in a clockwise direction, thereby enabling The head 3 gear 33 (see Fig. 7) rotates and causes the nut to rotate. Similarly, when the grip portion 2 is rotated in the counterclockwise direction, the transmission assembly 4 is in an idling state, and the nut does not rotate.

In summary, the knob 61 can be used to switch the grip portion 2 in the overall swing mode and the local swing mode, and the grip portion 2 can be used in a narrow space through the transmission assembly 4 in the local swing mode. Because of the large swing angle, it has a labor-saving effect. At the same time, the head 3 and the grip 2 are rigidly connected by the knob 61 to have a high torque value, so that the object of the present invention can be achieved.
