  • the second arm 10 is embedded in the pivoting slot 533 of the top cover 55, so that the first portion 551 and the second portion 552 of the top cover 55 are respectively located on opposite sides of the second arm 10, and are pivoted to the assembly 40.
  • the first pivot hole 11 and the second pivot hole 554 are respectively disposed to pivotally connect the second arm 10 to the top cover 55, so that the ratchet assembly 50 is aligned with the first rotational axis A as an axis.
  • the second arm 10 rotates.
  • the first arm 30 has a pivot portion 31 at one end and a trigger portion 32 at the other end.
  • the pivot portion 31 matches the shape of the first through hole 521, the second through hole 531, the third through hole 541, and the fourth through hole 557 such that the pivot portion 31 can be pivotally received in the ratchet assembly 50.
  • the trigger portion 32 can be in the shape of an Allen key, but not limited thereto, the shape of the trigger portion 32 can be a shape, a cross H type, a cross Z type, a plum type, a quad angle type, a three-wing type, Wing-shaped cross, snake-eye, one-way screw, double hexagon, octagonal, Bristol, etc.
  • the balls 56 are moved into different limiting slots, for example, moving the outer casing 51 downward, so that the balls 56 enter the second limiting slot 513 located below, at this time, the first ratchet The member 52 cooperates with the first ratchet end face 516.
  • the implementer rotates the second arm 10, that is, applies a torque to the second arm 10, and the torque is transmitted to the first ratchet member 52 and the first ratchet end surface 516 through the outer casing 51.
  • the first ratchet member 52 and the first ratchet end surface 516 are pressed against each other, thereby pressing the first arm 30, and applying a torsion force to the first arm 30, so that the first arm 30 can be driven in the first direction to rotate. And slips in the second direction and cannot be rotated.
  • the implementer rotates the second arm 10, that is,
  • the second arm 10 applies a torsion force transmitted through the outer casing 51 to the second ratchet member 53 and the second ratchet end surface 517, and the second ratchet member 53 and the second ratchet end surface 517 are pressed against each other, thereby pressing the first arm
  • the arm 30 applies a torsion force to the first arm 30 so that the first arm 30 can be rotated in the second direction to rotate, and the first direction is slipped and cannot be rotated.
  • the balls 56 are located at different positions, so that the first arm can be rotated in different directions, and the function of the one-way clutch is realized.
  • the contact area of the ratchet member and the ratchet end face is large, and only the axial force, there is no component force in other directions, thereby improving the torque.

Abstract

L'invention concerne une clé réglable comprenant un premier bras (30) et un ensemble rochet (20, 50) assemblé de manière rotative au premier bras, l'ensemble rochet comprenant un élément de changement de direction (24, 56) et un élément d'entraînement (25, 52, 53, 516, 517). L'ensemble rochet est configuré de sorte que lorsque l'élément de changement de direction est dans une première position, l'élément d'entraînement permet au premier bras de tourner dans une première direction, lorsque l'élément de changement de direction est dans une seconde position, l'élément d'entraînement permet au premier bras de tourner dans une seconde direction, et la première direction est inverse à la seconde direction. Par la fourniture d'une force de couple au premier bras par l'intermédiaire de l'ensemble rochet, le premier bras peut présenter une fonction similaire à une fonction d'un embrayage unidirectionnel. La clé réglable comprend en outre un second bras (10) et peut être commutée vers une forme de clé ou une forme de tournevis par le réglage d'un angle entre le premier bras et le second bras.
