Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
A kind of reversing mechanism of ratchet spanner as shown in Figures 1 to 6, a kind of commutating structure of ratchet spanner, including hand
Handle 1, spanner head assembly, the spanner head assembly include ratchet circle 2, rotary body 3 and coupled ratchet 4, and the ratchet circle 2 can be rotated
Ground is set in the handle 1, and the rotary body 3 is set in the ratchet circle 2, and the peripheral wall of the rotary body 3 is provided with peace
Tankage 32, the coupled ratchet 4 are articulated in the mounting groove 32 by installation axle 5, the coupled ratchet 4 and the ratchet circle
2 engagements, ratchet circle 2 are rotated by 4 driving rotating bodies 3 of coupled ratchet, realize power output.
The both ends of the coupled ratchet 4 are respectively arranged with the ratchet 41 engaged with the ratchet circle 2, the mounting groove 32
The stop surface 321 with the both ends counter stopper of the coupled ratchet 4 is formed on cell wall, the front end of the handle 1 is additionally provided with
Turn to turn round 6 with what the ratchet circle 2 engaged forward or backwards for controlling the coupled ratchet 4, the center projection of described turn of torsion 6
There is newel 61, the newel 61 is inserted in the centre bore 31 of the rotary body 3, is radially equipped in the newel 61
Post holes 62, the newel 61 are provided with reversing piece 63, and reversing piece 63 is fixed in post holes 62, and reversing piece 63 is T-shaped bullet
Property part, reversing piece 63 has first end 631, the second end 632 opposite with first end 631, and first end 631 extends to
One end of 4 medial surface of coupled ratchet, the second end 632 extend to the other end of 4 medial surface of coupled ratchet.One end of coupled ratchet
The other end inside that inside is provided with the first convex surface 42, coupled ratchet that cooperate with first end 631 is provided with and the second end
Second convex surface 43 of 632 cooperations, to guarantee that fitting is close.Spacer pin 64, spacer pin 64 and reversing piece are additionally provided in post holes 62
63 offset so that reversing piece 63 to be fixed in post holes 62, turn to turn round 6 by spacer pin 64 and the cooperation of 1 anti-avulsion of handle, turn round 6 to prevent rotation stop
