FIELD OF THE INVENTION
The present invention relates to a manual device which is provided with means to adjust two holding arms thereof in accordance with the size of an object to be picked up by the device.
BACKGROUND OF THE INVENTION
As shown in
FIGS. 1 and 2
, a prior art manual device is designed to pick up an object and is formed of a handle
10
, a fixed member
11
, a movable member
12
, two connection rods
15
and
16
, and two holding arms
13
and
14
. The fixed member
11
is fastened at one end with the handle
10
and is provided with two lugs
111
and
112
for pivoting the two connection rods
15
and
16
, which are provided with a pivoting portion
152
,
162
. The two holding arms
13
and
14
are pivoted at one end
131
,
141
with the other end
151
,
161
of the connection rods
15
,
16
in conjunction with the movable member
12
and a locating pin
18
. The movable member
12
is provided with an extension rod
121
and a spring
17
fitted over the extension rod
121
. The extension rod
121
is connected via the fixed member
11
to an activation cord
19
which is disposed in the interior of the handle
10
. In operation, activation cord
19
is triggered to cause the two holding arms
13
and
14
to move toward each other to grasp an object.
Such a prior art device as described is defective in design because the movable member
12
is not provided with means to adjust the distance between the two holding arms
13
and
14
in accordance with the size of an object to be picked up. It is therefore conceivably inconvenient to pick up the object with the prior art device. In addition, the prior art device is not provided with means to locate the activation cord
19
so as to enable the two holding arms
13
and
14
to take hold of the object continuously. Moreover, the holding arms
13
and
14
cannot be changed in the holding direction.
BRIEF SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a device for picking up an object. The device comprises a grasping member, a shank, an activation rod, a control lever, and a hand grip. The grasping member is formed of two grasping arms, and an adjustment piece which is engaged with an action end of the grasping arms. The shank is fastened at one end with the grasping member and at the other end with the hand grip. The activation rod is fastened at one end with the adjustment piece, and at the other end with the control lever which is pivoted at one end with the hand grip. The adjustment piece enables the two grasping arms to move toward or away from each other in accordance with the size of an object to be picked up. The hand grip is provided with means to locate the control lever so as to enable the two grasping arms to remain in the state of taking hold of the object.
The features and the advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of the present invention with reference to the accompanying drawings.
