Description
FIELD OF THE INVENTION
The present invention relates generally to a gardening shears, and more particularly to handles of the gardening shears.
BACKGROUND OF THE INVENTION
As shown in
FIGS. 1 and 2
, a gardening shears
10
of the prior art comprises a fastening rod
11
for fastening pivotally a handle
12
in conjunction with a position confining bolt
13
which is retained at one end thereof in a retaining groove
14
of the free end of the fastening rod
11
, as shown in FIG.
4
. The handle
12
is provided at one end thereof with a protruded block
16
, whereas the fastening rod
11
is provided with a stop edge
15
opposite to the protruded block
16
of the handle
12
for enabling the handle
12
to be swiveled at an angle. The handle
12
is so designed as to facilitate the holding of the handle
12
by hand for a prolonged period of time without the muscle pain or discomfort of the hand.
Such a prior art gardening shears
10
as described above is defective in design in that the handle
12
must be constantly readjusted in its position while the gardening shears
10
is in use, and that the user of the gardening shears
10
is conceivably annoyed at such an inconvenience, and further that the hand
2
holding the handle
12
is susceptible to bruise by a twig
1
, as illustrated in
FIG. 6
, and still further that the gardening shears
10
can not be securely held in the hand
2
in light of the way by which the handle
12
is designed to be held by the hand
2
, as illustrated in FIG.
7
.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in
FIGS. 8
, a gardening shears
20
embodied in the present invention comprises a shaft rod
21
for fastening pivotally a rotatable handle
22
which is provided with a confining bolt
23
. The shaft rod
21
is provided at the free end thereof with a retaining groove
24
in which one end of the confining bolt
23
is retained, so as to prevent the handle
22
from becoming detached from the shaft rod
21
, as illustrated in
FIGS. 8
,
9
, and
10
.
The gardening shears
20
of the present invention is characterized by the handle
22
which is provided in the fastening end thereof with a receiving cell
25
and a rotary spring
26
disposed in the receiving cell
25
. The rotary spring
26
has two retaining ends
27
, which are inserted into the root portion of the shaft rod
21
and a retaining hole
28
in the receiving cell
25
of the fastening end of the handle
22
. The retaining groove
24
of the shaft rod
21
has a predetermined length, as shown in
FIGS. 11 and 12
, thereby allowing the handle
22
to be swiveled in a predetermined range. In addition, the retaining hole
28
of the root portion of the shaft rod
21
or the handle
22
may be one or more in number so that the retaining ends
27
of the rotary spring
26
may be retained in different positions to provide the handle
22
with the swiveling forces different in magnitude.
As shown in
FIGS. 13
,
14
, and
15
, the handle
22
is provided in the fastening end thereof with an arcuate recess
31
in place of the receiving cell
25
, and a tension element
32
in place of the rotary spring
26
. The shaft rod
21
is provided in the root portion thereof with a support hole
33
and a bar
34
disposed in the support hole
33
such that one end of the bar
34
arrests one end of the tension element
32
, thereby enabling the handle
22
to swivel automatically.
As shown in
FIGS. 16 and 17
, the handle
22
of the second preferred embodiment of the present invention is provided with an arcuate portion
201
which is separated from the handle
22
by a space
202
dimensioned to allow fingers to put therethrough. In operation, the arcuate portion
201
serves to protect fingers from being bruised by a twig
1
of the garden plant, as illustrated in FIG.
18
. In addition, the arcuate portion
201
serves to prevent the gardening shears
20
of the present invention from slipping away from the hand, as illustrated in FIG.
19
. It must be noted here that the handle
22
and the arcuate portion
201
are made integrally. As shown in
FIG. 20
, the handle
22
of the third preferred embodiment of the present invention is provided with an arcuate portion
201
which is detachable attached to the handle
22
. The handle
22
is provided at two opposite ends thereof with a tenon
203
, whereas the arcuate portion
201
is provided at two opposite ends thereof with a mortise
204
corresponding in location to and engageable with the tenon
203
. In the event that the arcuate portion
201
is damaged, it can be readily replaced with a new one.
The preferred embodiments of the present invention described above are to be regarded in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scopes of the following appended claims.
