Problems solved by technology

However, the existing adjustable wrench with reversing function usually has a relatively large volume in order to ensure sufficient torque, so it is inconvenient to move in a place with a small activity space, and in order to reduce the volume, the torque of the wrench will be insufficient.

Embodiment Construction

[0112] The X, Y, and Z lines marked in the figure are perpendicular to each other.

[0113] Figures 1 to 4B An adjustable wrench in a first embodiment of the present invention is shown, which includes: a first arm 30 , a ratchet assembly 20 and a second arm 10 . The ratchet assembly 20 is assembled with the first arm 30 in a rotatable relationship, wherein the ratchet assembly 20 includes a reversing component and a pushing component.

[0114] Wherein, the ratchet assembly 20 is configured such that: when the reversing member is in the first position, the pushing member can rotate the first arm 30 in the first direction; when the reversing member is in the second position, the pushing member can rotate in the second direction. The first arm 30 is rotated in the direction; the first direction and the second direction are mutually opposite directions.

[0115] The second arm 10 is mutually assembled with the ratchet assembly 20 in a rotatable relationship. The ratchet assemb...

Abstract

The invention discloses an adjustable spanner which comprises a first arm and a ratchet wheel assembly rotationally assembled and connected with the first arm, wherein the ratchet wheel assembly comprises a reversing component and a pushing component; the ratchet wheel assembly is configured to be that when the reversing component is in a first position, the pushing component can allow the first arm to rotate in the first direction, and when the reversing component is in a second position, the pushing component can allow the first arm to rotate in the second direction; and the first directionand the second direction are mutually opposite. The ratchet wheel assembly provides torsion to the first arm, so that the first arm has a function similar to a one-way clutch. The adjustable spanner further comprises a second arm, and can be switched into a spanner state or a screwdriver state by adjusting an angle between the first arm and the second arm.

Description

technical field [0001] The invention relates to a wrench, in particular to an adjustable wrench. Background technique [0002] Existing adjustable wrenches are generally L-shaped integrally formed, including a long arm and a short arm, and generally the long arm and the short arm form an included angle of 90°. However, since the long arm and the short arm are connected by a pin shaft, the angle between the long arm and the short arm cannot be adjusted, so the use at a specific angle cannot be maintained, which limits the scope of application of the wrench. [0003] There are also some adjustable wrenches that utilize a pivot to connect the long arm and the short arm, and the angle of the long arm and the short arm can be changed at will. However, the existing adjustable wrench with reversing function usually has a relatively large volume in order to ensure sufficient torque, so it is inconvenient to move in a place with a small movable space, and in order to reduce the volu...
