The radial perforation 18 is just in the position of the annular groove 23, so that the ratchet head 20 can only rotate and cannot be disengaged, and the toggle of the dial 30 causes the bending ratchet wrench to change clockwise. Or reverse clock drive or all idle, and the longer shaft can also be accommodated by the axis through hole 12, so that the bend ratchet wrench can still work normally.

The axis passes through a curved ratchet wrench, wherein the two ratchet blocks 42, 43 are provided with a plurality of ratchet teeth 421, 431 in the direction corresponding to the ratchet teeth 22.

a plurality of curved ratchet wrenches, wherein the two stops 32, 33 are disposed on the two ratchet blocks 42, 43 on both sides of the ratchet 22, and the two ratchet blocks 42, 43 are The baffles 32, 33 should be respectively provided with a slope 422, 432, so that the ratchet blocks 42, 43 can be blocked when they travel to the brace 32, 33, and the slopes 422, 432 are slid to the brace 32, 33 is pushed outward, so that the ratchet teeth 421, 431 of the ratchet blocks 42, 43 are away from the ratchet teeth 22 of the ratchet head 20, so that the direction is idling.

The axis runs through the curved ratchet wrench, which is gradually smaller The eccentric bore 13 forces the ratchet teeth 421, 431 of the ratchet blocks 42, 43 to securely engage the ratchet teeth 22 of the ratchet head 20 such that the direction of rotation is a mover.

a plurality of curved ratchet wrenches, wherein the two ratchet blocks 42, 43 are located at the widest position of the eccentric stepped holes 13, so that the ratchet teeth 421, 431 of the two ratchet blocks 42, 43 can be detached from the The ratchet teeth 22 of the ratchet head 20 are engaged such that both directions of rotation are idling.

Referring to the first, second, fourth and fifth figures, when the dial rotates the dial 30 of the ratchet wrench, the concave hole 15 of the bending handle wrench 10 is placed, and the spring 16 pushes the positioning steel ball 17, positioning Up to the positioning recess 36 of the dial 30 (as shown in the fourth figure), the two ratchet blocks 42, 43 are located at the widest position of the eccentric step 13 and away from the two stops 32, 33, and the The top post 34 is also located at a central position of the elliptical arc groove 14 (as shown in FIG. 5) such that the ratchet teeth 421, 431 of the two ratchet blocks 42, 43 can be disengaged from the ratchet teeth 22 of the ratchet head 20. So that the two directions of rotation are idling.

Referring to the first, second, sixth, and seventh figures, when the dial rotates the dial 30 of the ratchet wrench, the concave hole 15 of the curved wrench rod 10 is placed, and the spring 16 pushes the positioning steel ball 17, positioning Up to the positioning recess 35 of the dial 30 (as shown in the sixth figure), wherein the top post 34 is located on the lower side of the elliptical arc groove 14, and the eccentric step 13 is rotated clockwise to force the ratchet block The ratchet teeth 421 of 42 securely engage the ratchet teeth 22 of the ratchet head 20 such that the direction of rotation is a mover. When the ratchet block 43 travels to the stop 33, it is blocked, and the inclined surface 432 is slid to the stop 33 and pushed outward, thereby making the ratchet The ratchet teeth 431 of the block 43 are remote from the ratchet teeth 22 of the ratchet head 20 such that the counterclockwise rotation is idling.

Referring to the first, second, eighth and ninth diagrams, when the dial rotates the dial 30 of the ratchet wrench, the concave hole 15 of the bending handle wrench 10 is placed and the spring 16 pushes the positioning steel ball 17, positioning To the positioning recessed hole 37 of the dial 30 (as shown in the eighth figure), wherein the top post 34 is located on the upper side of the elliptical arc groove 14, the counter-clockwise rotation gradually decreases the eccentric step hole 13 to force the ratchet block The ratchet teeth 431 of 43 securely engage the ratchet teeth 22 of the ratchet head 20 such that the direction of rotation is a mover. When the ratchet block 42 travels to the stop post 32, it is blocked, and the inclined surface 422 is slidably moved to the stop post 32 to be pushed outward, so that the ratchet teeth 421 of the ratchet block 42 are away from the spine of the ratchet head 20 The teeth 22 are such that the counterclockwise rotation is idling.

It can be seen from the above that the curved ratchet wrench of the core of the creation is indeed the first in the industry and meets the novelty requirements of the new patent, and its comprehensive and innovative design meets the progressive requirements of the new patent, and the encounter The longer shaft body can also be accommodated by the axial through hole, so that the curved ratchet wrench can still work normally, which is in line with better industrial applicability.
