Remote trimming tool

This creation relates to a distal trimming tool, and more particularly to an adjustment mechanism for a distal trimming tool that is used to trim tall branches or harvest fruits.

A distal trimming tool (high branch shear) for trimming tall branches or harvesting fruits, and some non-rotating scissors unit directions, such as US Patent Publication Nos. US1209999, US1761469, US2664628, US3360859, US5241752, US1181579, US2203926, US4760645, US8069573, US8046925 Etc., the branches or fruits that are in the direction of trimming cause some inconvenience. Thus, the re-derived high-pruning shears allow the user to adjust the orientation of the scissor unit, for example, U.S. Patent No. 6,694,621, U.S. Patent No. 6,674,663, U.S. Patent No. 7,685,011, U.S. Patent No. 5,950, 315, U.S. Patent No. 5,317, 806, U.S. Pat.

The adjustment technique and structure of the above-mentioned directional adjustment mechanism are different, and the US6694621 case uses a screw loosening and locking scissors unit. In the case of US Pat. No. 6,674, 863, US Pat. No. 7,685, 011, US Pat. No. 5,950, 315, and US Pat. No. 6,110,107,606, each of which is provided with a ratchet or a serrated portion respectively at two oppositely rotating portions, but has no design for temporarily locking the ratchet or serration when rotating. , so when the butterfly button (Wingnut) is loosened, the two ratchets or serrations It will be completely separated, and its scissors unit will turn around indefinitely. For example, the moment the butterfly button is released, the scissors unit will suddenly sag due to the weight. It needs to raise the scissors unit with one hand and lock the butterfly button with the other hand. It is therefore inconvenient to adjust the angle. The US5317806 case is also fixed using a butterfly button, but no ratchets form a bite. The US8220163 only uses a control unit to limit the rotation of the scissors unit between two angles, and the angle at which it can be adjusted is limited. US 5,347,800 discloses the use of a transverse axis to form a frictional pivotal connection, but after a period of use, the pressing friction will be relaxed and the direction cannot be maintained.

In addition, it is necessary to use a structure in which the two ratchets are engaged with each other, and the hand tool is used as a mechanism for directional rotation. Although it is already a disclosed technique, how to temporarily position the ratchet when it is rotated, and after adjusting to a specific angle Quickly locking, the related technology still needs to be improved. For example, the above-mentioned butterfly button or screw is used for locking. Because the number of turns is too large, it is easy to cause inconvenience in adjustment. The user often does not know that it is necessary to make a few turns to lock. tight. However, some of the steps for unlocking and locking are too complicated. The steps such as pulling out the knob, turning an angle, and then pressing the rotary button are quite troublesome. In addition, when the ratchet wear or the elastic element that assists the ratcheting is weak, how to make the user easier to replace and repair is also an important issue of the adjustment mechanism.

The main purpose of the present invention is to provide a distal trimming tool that pushes the spine by integrally forming a ratchet portion on one side of the scissors unit, a ratchet disk corresponding to the ratchet portion, and an elastic member that pushes the ratchet disk. The toothed disc engages with the ratchet and maintains the direction in which the scissors unit can rotate. After the scissors unit is released, the problem of non-directional rotation is achieved, and the effect of directional adjustment angle is achieved.

The second objective of the present invention is to provide a distal trimming tool that can be used to push the ratchet disc to engage the ratchet portion of the scissor unit when rotating at a fixed angle through a wedge-shaped wedge design on the inner side of a quick-turn knob (or vice versa) Loosen) to achieve the effect of quickly locking or unlocking the scissors unit.

Another object of the present invention is to provide a distal trimming tool that is designed as a separate component through a ratchet disk and an elastic element, making it easier to assemble and repair.

The design of the elastic element 4 does not completely block the ratchet disc 3 axially, so that the ratchet disc 3 has a little axial movement space, so the first ratchet portion 16 of the seat 11 and the second of the ratchet disc 3 The ratchet portion 32 can be engaged, and the blade holder 11 can also be rotated and adjusted in a specific direction (angle), so that the entire scissors unit 1 suddenly falls down when the knob 5 is released.

The knob 5 is used for locking or unfastening the object of the scissors unit 1 , and can be implemented as a disk body corresponding to the second pivoting portion 21 of the connecting member 2 so as to be rotatably disposed on the second pivoting portion 21 . An outer side surface 212 has a torsion portion 51 that provides a force, and one or more wedge members 52 are provided on one side of the ratchet disk 3. The torsion portion 51 may be one or two protrusions 511 protruding from the other surface or the edge of the knob 5 or other structures for convenient force application. Each of the wedges 52 has a slope 521 that pushes the ratchet disk 3 through the slope 521 to lock or unlock the first ratchet portion 16 of the blade holder 11. Therefore, the knob 5 can be rotated between a first angle A (as shown in the fifth figure) and a second angle B (as shown in the ninth figure), so that the slope 521 of the wedge 52 is at the first Pushing the ratchet disc 3 between the angle A and the second angle B, so that the second of the ratchet disc 3 The ratchet portion 32 is tightly engaged or relaxed (not completely separated) from the first ratchet portion 16 of the first pivot portion 15.

Further, as shown in the third and fourth figures, a partition wall 213 is disposed between the inner side surface 211 and the outer side surface 212 of the second pivoting portion 21 of the connecting member 2, and the partition wall 213 is provided with one or more Opening 214. The second surface 33 of the ratchet disk 3 is provided with one or more protrusions 34 passing through the opening 214. The protrusions 34 may be protrusions or convex balls or other shapes, so that the protrusions 34 abut against the knob 5 The inclined surface 521 of the wedge wedge 52 can axially push the ratchet disk 3 when the knob 5 is rotated. The elastic member 4 is preferably disposed between the partition wall 213 and the ratchet disk 3 and pushes against the second face 33 of the ratchet disk 3, whereby the elastic member 4 has a supporting reference (partition wall 213). Further, the ratchet disk 3 is elastically driven. Furthermore, the other second pivoting portion 21' of the connecting member 2 not corresponding to the first ratchet portion 16 can be implemented as a ring body 215' and a side cover 216' covering the ring body 215'.

As shown in the third and fourth figures, the outer side surface 212 of the second pivoting portion 21 of the connecting member 2 can be provided with two limiting slots 217, and the two ends of the limiting slot 217 have an angle. The first angle A and the second angle B are respectively provided; and the edge of the button 5 is provided with two limiting stops 53 so that the limiting stops 53 respectively extend into the limiting slots 217, so that The knob 5 is restricted from rotating between the first angle A and the second angle B, so that the problem of excessive rotation does not occur. More specifically, the outer side surface 212 of the second pivoting portion 21 of the connecting member 2 may be provided with a recessed hole 218, and the two limiting slots 217 are recessed in the hole wall of the recessed hole 218; The first surface of the button 5 is provided with a convex ring 54 that fits in the recessed hole 218, and the outer ring surface of the convex ring 54 is provided with the above two The limit stop 53 can make the rotary knob 5 more convenient to rotate in the outer side surface 212 of the second pivoting portion 21 .

The creation is different from the conventional butterfly button and bolt, and the ratchet disc 3 is pushed through the wedge 52 of the knob 5, so that the knob 5 can be set to rotate between the first angle A and the second angle B, and In order to ensure that the inclined surface 521 of the wedge member 52 and the convex portion 34 of the ratchet disk 3 rotate within a defined angle, as shown in the fourth figure, the inclined wedge block 52 is preferably implemented in a plurality of successively formed convex portions. The inner side or the outer side of the ring 54 (shown as the inner side of the convex ring 54), and a blocking portion 522 is respectively disposed at both ends of the inclined surface 521 of the inclined wedge block 52, so that the convex portion 34 of the ratchet disk 3 abuts against the second stop. The inclined surface 521 between the portions 522 also has a function of not excessively rotating.

Further, as shown in the third and sixth figures, the present invention preferably further includes a bolt 6 and a nut 7 for threading the bolt 6 through the side cover 216' and the first pivoting portion 15 of the seat 11. , 15', the second pivoting portions 21, 21' of the connecting member 2, the ratchet disc 3, the elastic member 4 and the center of the rotary knob 5, the end of the bolt 6 abuts against the side cover 216', and the nut 7 It is locked at one end of the bolt 6, and thus axially blocks the rotary knob 5, so that the above-mentioned members are axially combined and can be disassembled if necessary to replace and repair the above-mentioned members.

As shown in the fifth and sixth figures, when the scissors unit 1 needs to adjust the direction of use (angle), the knob 5 can be first turned to the first angle A, and the role of the rotation is as shown in the seventh figure. The wedge wedge 52 is relatively moved to a lower point of the slope 521, so that the ratchet disk 3 has an axially movable space, but is pushed through the elastic member 4, and the ratchet disk 3 is not completely complete with the first ratchet portion 16. It is detached, so that the problem that the scissors unit 1 falls down instantaneously does not occur. When the user turns the scissors In the knife unit 1, the component force of the first ratchet portion 16 pushes the ratchet disk 3 backward (shown in FIG. 6), and then the ratchet disk 3 is pushed through the elastic member 4 and snapped to the ratchet portion 16, so The scissors unit 1 can be easily adjusted to a specific direction.

As shown in the ninth and tenth figures, after the scissors unit 1 is adjusted, the knob 5 is turned to the second angle B, and the action of the rotation is as shown in the eighth figure, so that the wedge wedge 52 is relatively moved. Turning to the higher point of the inclined surface 521, the inclined wedge 52 is used to bear against the convex portion 34 of the ratchet disk 3, so that the ratchet disk 3 has no space to move backward, and the second ratchet portion 32 will closely engage the first ratchet The portion 16 prevents the scissors unit 1 from rotating any more.

In summary, the remote pruning tool of this creation has been practical and creative, and its technical means are also novel and undoubted, and the efficacy and design purpose are in line with the fact that it has been reasonably improved. To this end, a new type of patent application is filed in accordance with the law, but the bureau is requested to give a detailed examination and grant the patent as a prayer.
