1. Field of the Invention
This invention relates to a ratcheting wrench, more particularly to a ratcheting wrench with a hammer bell detachably mounted on a mounted seat and angularly displaced from a ratcheting drive shaft for performing dual functions.
2. Description of the Related Art
Referring to
The object of the present invention is to provide a ratcheting wrench which can perform both ratcheting and hammering operations.
According to this invention, the ratcheting wrench includes a handle body which extends in a longitudinal direction and which terminates at an upper handle end, a mounting seat which is disposed on the upper handle end, and which includes right and left walls opposite to each other in a first transverse direction relative to the longitudinal direction, and front and rear walls interposed between the right and left walls and opposite to each other in a second transverse direction relative to both the longitudinal direction and the first transverse direction, a ratcheting fastening mechanism which includes a ratchet wheel assembly that is disposed in the mounting seat between the right and left walls, and that is actuated to be rotated, and a drive shaft that extends outwardly from the front wall in the second transverse direction, and that is coupled with the ratchet wheel assembly to rotate with the ratchet wheel assembly, a hammer bell which has a hammer face end and an engaging end opposite to each other in the first transverse direction, and a coupling member which is disposed to detachably couple the engaging end with the left wall.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment of the invention, with reference to the accompanying drawings, in which:
Referring to
The handle body 2 includes a lower grip end 21 and an upper handle end 22 extending from the lower grip end 21 in a longitudinal direction. The mounting seat 3 is disposed on the upper handle end 22, and includes right and left walls 35,34 opposite to each other in a first transverse direction (x) relative to the longitudinal direction, and front and rear walls 32,33 interposed between the right and left walls 35,34 and opposite to each other in a second transverse direction (y) relative to both the longitudinal direction and the first transverse direction (x). The ratcheting fastening mechanism 4 includes a known ratchet wheel assembly 42 which is disposed in the mounting seat 3 between the right and left walls 35,34, and which is rotatable, and a drive shaft 41 which extends outwardly from the front wall 32 in the second transverse direction (y), and which is coupled with the ratchet wheel assembly 42 so as to rotate therewith.
The first hammer bell 5 is made from metal or rubber material, and has a first hammer face end 51 and a first engaging end 53 opposite to each other in the first transverse direction (x). The first coupling member includes a first threaded bore portion 36 which is formed in the left wall 34 and which has an internally threaded surface that extends in the first transverse direction (x), and a first threaded shank 52 which is disposed to extend from the first engaging end 53 in the first transverse direction (x) and which has an externally threaded surface that is threadedly engaged with the internally threaded surface of the first threaded bore portion 36 such that the first hammer bell 5 is detachably coupled to the mounting seat 3.
As illustrated, since the hammer bell 5 is disposed to extend transverse to the drive shaft 41, the ratcheting fastening mechanism 4 and the hammer bell 5 will not interfere with each other during fastening or hammering operation.
Furthermore, referring to
While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretations and equivalent arrangements.
