ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a rotational handgrip, especially to a rotational handgrip, which can be adjusted to various degrees for easy use.
BACKGROUND OF THE INVENTION
The conventional baggage trailer
11
a
with wheel
10
a
is generally has telescopic link
12
a
with a handgrips
13
a
. The telescopic link
12
a
can be shrunk or extracted and the user pushes or pulls the baggage trailer
11
a
on the handgrips
13
a.
However, the angle of the handgrips
13
a
in the conventional baggage trailer
11
a
with wheel
10
a
cannot be adjusted. The handgrips
13
a
is parallel with the telescopic link
12
a
such that the baggage trailer
11
a
has small inclining angle with respect to ground. The user should exert larger force to push or pull the baggage trailer
11
a.
Moreover, by using the handgrips
13
a
, the user may be stumbled by the baggage trailer
11
a.
It is the object of the invention to provide a rotational handgrip for baggage trailer, which can be adjusted to various degrees for easy use and not stumbling user.
To achieve above object, the present invention provides a rotational handgrip for baggage trailer comprising a main body having two hollow pipes on both sides thereof and two link connectors. The hollow pipes have receiving holes each housing a clamping bead, and the bead can be pushed outward. The two link connectors each has a plurality of clamping hole; and the two hollow pipes are pivotally arranged on the two link connectors such that the main body can be rotationally adjusted and the bead can be moved outward and fixed on the clamping hole to clamp the main body.
