Description
PRUNING HOOK HAVING AN ENERGY-SAVING FUNCTION
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a shearing tool and, more particularly, to a pruning hook for a gardening purpose to shear branches or leaves at a higher location.
2. Description of the Related Art
A pruning hook is used to shear branches of a tree at a higher location.
A conventional pruning hook in accordance with the prior art shown in Fig. 8 comprises an extension pipe 50, a fixed blade 61 mounted on a front end of the extension pipe 50, a movable blade 62 pivotally connected with and movable relative to the fixed blade 61, a pull cord 52 connected with the movable blade 62 to drive the movable blade 62 to move relative to the fixed blade 61, a* control sleeve 51 movably mounted on the extension pipe 50 and connected with the pull cord 52 to drive and move the pull cord 52, a guide pulley 64 rotatably mounted on a first end of the movable blade 62 for mounting the pull cord 52, and an elastic member 63 biased between a second end of the movable blade 62 and the fixed blade 61 to drive the movable blade 62 to move outwardly relative to the fixed blade 61. The extension pipe 50 has an outer wall provided with a hollow stop portion 53 to stop the control sleeve 51. The fixed blade 61 has an inner portion provided with a connecting hole 65 connected to the inner portion of the extension pipe 50 to allow passage of the pull cord 52. The pull cord 52 is pivotally mounted on the guide pulley 64 and extends through the connecting hole 65 of the fixed blade 61 into the inner portion of the extension pipe 50. The pull cord 52 has a first end 520 secured on the fixed blade 61 and a second end 521 extended outward from the stop portion 53 of the extension pipe 50 and secured on the control sleeve 51.
In operation, when the control sleeve 51 is moved outwardly relative to the fixed blade 61, the pull cord 52 is driven by the control sleeve 51 to move the guide pulley 64 which drives the movable blade 62 to move toward the fixed blade 61 so as to perform a cutting action. On the contrary, when the pulling force applied on the control sleeve 51 disappears, the movable blade 62 is driven by the restoring force of the elastic member 63 to move outwardly relative to the fixed blade 61 so that the movable blade 62 and the fixed blade 61 are opened at a normal state.
However, when the object to be cut by the movable blade 62 and the fixed blade 61 is too large or hard, the pull cord 52 cannot withstand the larger pulling force applied by the user, so that the pull cord 52 is easily deformed by the tensile force and cannot directly transmit the pulling force to the movable blade 62, thereby decreasing the working efficiency of the movable blade 62.
In addition, the control sleeve 51 is moved by the restoring force of the elastic member 63 to abut and hit the stop portion 53 of the extension pipe 50 so that the stop portion 53 of the extension pipe 50 is easily worn out or broken by hit of the control sleeve 51, thereby affecting operation of the pull cord 52.

The extension shank 11 is provided with a passage 115 connected to the receiving chamber 111 to allow passage of the first end 41 of the pull cord 40.
The extension shank 11 is further provided with a fixing hole 117 connected to the receiving chamber 111. The extension shank 11 is further provided with a * pin hole 114 and a snap-fit hole 116 each connected to the receiving chamber 111.
The holding member 12 has a periphery provided with a protruding connecting portion 121 connected with the first end 41 of the pull cord 40 to drive and move the first end 41 of the pull cord 40. The holding member 12 is located outside of the extension shank 11 and is movable on the extension shank 11 to abut the stop sleeve 15 so that the stop sleeve 15 can limit a further movement of the holding member 12 toward the blade unit 13.
The stop sleeve 15 is located between the passage 115 of the extension shank 11 and the holding member 12. The stop sleeve 15 has an inner portion provided with a mounting hole 150 mounted on the extension shank 11 and has a sidewall provided with an axially extending guiding channel 153 connected to the mounting hole 150 to allow passage of the first end 41 of the pull cord 40. The stop sleeve 15 has a periphery provided with a locating hole 151 connected to the mounting hole 150, and the pruning hook 10 further comprises a fixing pin 152 extending through the locating hole 151 of the stop sleeve 15 and secured in the fixing hole 117 of the extension shank 11 to fix the stop sleeve 15 onto the extension shank 11.
The pulling handle 14 has a side provided with a fixing portion 141 connected with the second end 42 of the pull cord 40. The fixing portion 141 of the pulling handle 14 is removably inserted into the second end 113 of the extension shank 11.
* The fixed pulley unit 20 is provided with a plurality of first rollers 21.
The fixed pulley unit 20 has a side provided with a through hole 22 aligning with the pin hole 114 of the extension shank 11 and provided with an elastic snap-fit boss 24 snapped into the snap-fit hole 116 of the extension shank 11.
The pruning hook 10 further comprises a locating pin 23 extending through the pin hole 114 of the extension shank 11 and the through hole 22 of the fixed pulley unit 20 to fix the fixed pulley unit 20 in the extension shank 11.
Thus, when the snap-fit boss 24 of the fixed pulley unit 20 is snapped into the snap-fit hole 116 of the extension shank 11, the through hole 22 of the fixed pulley unit 20 is aligned with the pin hole 114 of the extension shank 11 to facilitate insertion of the locating pin 23 through the pin hole 114 of the extension shank 11 into the through hole 22 of the fixed pulley unit 20.
The movable pulley unit 30 is provided with a plurality of second rollers 31. The movable pulley unit 30 is movable in the receiving chamber 111 of the extension shank 11 and has a surface provided with a retaining portion 32 connected with the driving cord 131 to drive and move the driving cord 131.

The pull cord 40 is provided with a winding portion 43 which is defined between the first end 41 and the second end 42 of the pull cord 40. The winding portion 43 of the pull cord 40 is mounted between the fixed pulley unit * 20 and the movable pulley unit 30 and wound around the first rollers 21 of the fixed pulley unit 20 and the second rollers 31 of the movable pulley unit 30.
The first end 41 of the pull cord 40 extends through the passage 115 of the extension shank 11, the guiding channel 153 of the stop sleeve 15 and is secured on the connecting portion 121 of the holding member 12. The second end 42 of the pull cord 40 extends through the second end 113 of the extension shank 11 and is secured on the fixing portion 141 of the pulling handle 14.
In operation, referring to Figs. 3-7 with reference to Figs. 1 and 2, when the holding member 12 is driven by a user to move outwardly relative to the blade unit 13, the first end 41 of the pull cord 40 is driven by the holding member 12. At this time, the second end 42 of the pull cord 40 is fixed by the fixing portion 141 of the pulling handle 14. In such a manner, when the first end 41 of the pull cord 40 is driven by the holding member 12, the movable pulley unit 30 is driven by the pull cord 40 to drive the driving cord 131 so that the driving cord 131 is moved to drive and close the blade unit 13 as shown in Fig. 6 so as to perform a shearing or cutting action. On the contrary, when the pulling force applied on the holding member 12 disappears, the blade unit 13 is returned to an open state by its elastic restoring force as shown in Fig. 4 so that the blade unit 13 is opened at a normal state as shown in Fig. 1. At this time, the holding member 12 is moved toward the blade unit 13 to abut the stop sleeve as shown in Fig. 3 so that the holding member 12 stops moving.
Alternatively, when the pulling handle 14 is pulled by the user to move outwardly relative to the blade unit 13, the second end 42 of the pull cord is driven by the pulling handle 14. At this time, the first end 41 of the pull cord 40 is fixed by the connecting portion 121 of the holding member 12. In such a manner, when the second end 42 of the pull cord 40 is driven by the pulling handle 14, the movable pulley unit 30 is driven by the pull cord 40 to drive the driving cord 131 so that the driving cord 131 is moved to drive and close the blade unit 13 as shown in Fig. 7 so as to perform a shearing or cutting action. On the contrary, when the pulling force applied on the pulling handle 14 disappears, the blade unit 13 is returned to the open state by its elastic restoring force as shown in Fig. 4 so that the blade unit 13 is opened at a normal state as shown in Fig. 1. At this time, the pulling handle 14 is moved toward the extension shank 11 to abut the second end 113 of the extension shank 11 as shown in Fig. 3 so that the pulling handle 14 stops moving.
Accordingly, the pull cord 40 is mounted between the movable pulley unit 30 and the fixed pulley unit 20 so that when the pull cord 40 is pulled, the movable pulley unit 30 is moved relative to the fixed pulley unit 20 to drive the driving cord 131 and the blade unit 13 so as to perform a shearing or cutting action in an energy-saving manner by linking connection of the pull cord 40, the movable pulley unit 30 and the fixed pulley unit 20. In addition, the blade unit 13 is driven by the holding member 12 or the pulling handle 14 so that the blade unit 13 has two operation modes to facilitate a user operating * the pruning hook. Further, the stop sleeve 15 has a guiding channel 153 to guide movement of the pull cord 40 so that the pull cord 40 is driven by the holding member 12 smoothly. Further, the stop sleeve 15 is located between the passage 115 of the extension shank 11 and the holding member 12 to limit the moving distance of the holding member 12. Further, when the snap-fit boss 24 of the fixed pulley unit 20 is snapped into the snap-fit hole 116 of the extension shank 11, the through hole 22 of the fixed pulley unit 20 is aligned with the pin hole 114 of the extension shank 11 to facilitate insertion of the locating pin 23 through the pin hole 114 of the extension shank 11 into the through hole 22 of the fixed pulley unit 20 and to facilitate assembly of the fixed pulley unit 20 in the extension shank 11.
