ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a screw dispensing device and the device makes the screws be dispensed in a stable status, and screws with different sizes can be conveniently and easily replaced and engaged with the device.
BACKGROUND OF THE INVENTION
A conventional screw dispenser device is shown in
FIGS. 1 and 2
, and generally includes a sleeve
10
and a barrel which is connected to the sleeve
10
by a spring bush. A slide piece
12
is connected to a side of the barrel
11
and moves up and down with the relative movement of the barrel
11
and the sleeve
10
. An L-shaped pushing member
13
is pivotably connected to the slide piece
12
and a lever
131
extends from the pushing member
13
and protrudes out from the slide piece
12
. The lever
13
controls the pushing member
13
by a spring. A control shaft
14
is connected to the sleeve
10
and one end of the control shaft
14
contacts against one of the stepped surfaces of the stop member
15
, and the other end of the control shaft
14
contacts the barrel
11
. When changing the screws, the user has to shift the lever
131
of the pushing member
13
so as to engage the screws and pull the screws out. The finger feels paint to press on the lever
131
. The inner diameter of the barrel
11
is fixed so that the screws with smaller specification cannot be securely positioned in the barrel
11
. When using longer screws, the long screws could tilt when being dispensed because the distance between the screws and the barrel
11
is too far. A hole has to be drilled in the sleeve
10
to receive the control shaft
14
.
The present invention intends to provide a screw dispensing device wherein the slide piece and the pushing member are connected with each other to simplify the process of operation. An adjusting knob is used to control the travel length of the positioning plate so as to accommodate the screws with different sizes.
SUMMARY OF THE INVENTION
In accordance with one aspect of the present invention, there is provided a screw dispensing device and the primary object of the present invention is to provide a pushing member which is connected to the slide piece so as to simplify the processes of operation of the device. A rotatable adjusting knob is pivotably connected to the rear end of the positioning plate and controls the movement of the positioning plate.
Another object of the present invention is to provide a screw dispensing device wherein a movable positioning plate makes the screws with different sizes be easily inserted in the barrel of the device. It is not necessary to change the barrel when using different size of screws. The rotatable adjusting knob adjusts the depth of feeding of the screws.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
