Ratchet wrench with head capable of being shrunk

Abstract

The invention relates to a ratchet wrench with a head capable of being shrunk. The ratchet wrench comprises a body, a driving piece, a ratchet device and a reversing switch, wherein the body comprises the head, a connecting segment connected with one surface of the head, and a handle body arranged at the connecting segment oppositely to one end of the head, and a longitudinal connecting part connected with one surface of the head is formed at one end of the connecting segment; the driving piece is rotatably arranged at the head of the body; the ratchet device can be selectively meshed with the driving piece; and the reversing switch is pivoted with the driving piece and can control the ratchet device, a stirring ring of the reversing switch is tied and exposed outside the first surface of the head of the body and corresponds to the outer surface of the head of the body, and therefore, a user can stir the stirring ring of the reversing switch by the outer surface of the head of the body, thereby effectively reducing the radial distance of the head and achieving the effect of shrinking the head of the body.

Description

technical field [0001] The invention relates to a ratchet wrench, especially a bending angle ratchet wrench whose head can be extended into a concave environment in a narrow space. Background technique [0002] Please refer to US Patent No. 7,093,520 "Gear wrench allowing easy force application", which is a ratchet wrench (gear wrench), one end of the ratchet wrench forms a head, and a storage space is formed in the head (receiving compartment) is used to accommodate a rotatable ratchet ring (gear ring), the other end of the ratchet wrench forms a tail (tail), and a neck (neck) extends obliquely between the head and the tail, In addition, a recessed space (indent) and an aperture (aperture) are reserved between the neck and the head for installation of a direction switch. [0003] Since the direction switching switch is installed in the hole provided between the neck and the head, and a recessed space is reserved between the direction switching switch and the neck for the u...

AI Technical Summary

Problems solved by technology

[0007] Such an operation method still causes inconvenience in the construction process, because there is an additional selection procedure for the external extension tool, for example, the extension tool of the appropriate size must be selected according to the size of the work object

[0008] Moreover, carrying additional extension tools will also cause an increase in weight, or cause too many scattered tools that are not easy to organize or identify.

[0009] Therefore, on the whole, the working environment of the ratchet wrench designed with an inclined neck is still limited, and there is a recessed environment where the head cannot be extended into a small space for construction.
