A multi-functional garden pole pruner as shown in fig. 1-5, comprises a straight extending pole 100, which may have a length adjusting function. Two handles 400 hinged in an X-shape are provided at the upper end of the extension rod. One of the two handles is fixedly connected with the extension rod at the lower end so as to be fixedly held with the extension rod, and the other handle can freely rotate. It should be noted that, an interface is formed at the upper end of the two handles away from the extension rod, and the blade 500 or the clip strip 600 is detachably mounted in the interface. Specifically, the blade forms shearing action under the drive of the handle of upset to be used for pruning thinner branch and leaf, and the holding strip can then the centre gripping on thicker trunk under the handle effect of upset, in order to assist the cutting of follow-up thicker branch.

It should be noted that, in order to control the states of the two handles conveniently, a pulling mechanism 200 is further provided on the extension rod 100. Specifically, the pulling mechanism includes an L-shaped handle 230 hinged to the lower end of the extension rod 100, a support base 220 disposed on the extension rod, the support base being disposed as close to the L-shaped handle as possible, a pulling rope 210 connected to the free end of the L-shaped handle 230, and the pulling rope being stretched around the support base and having the other end connected to the lower end of the handle capable of freely rotating. When the two handles are required to be folded, the L-shaped handle 230 is only required to be held so as to lead the two handles to pull the first traction rope.

In addition, in order to realize the convenient sawing of thicker branches, the articulated department of two handles adopts the hollow shaft to connect, and this hollow shaft is inside to be the polygon cross-section, and a roof beam arm 800 passes through a polygon prism of predetermineeing, and the rethread nut detachable is fixed on the handle after the non-rotatable hollow shaft that passes.

It should be noted that, a reciprocating mechanism 900 is further disposed on an end of the beam arm 800 away from the handle, and a saw blade 700 is connected to the reciprocating mechanism. When the branches are sawn, the saw blade carries out reciprocating pull sawing on the surfaces of the branches under the action of the reciprocating mechanism so as to achieve the sawing effect.

In addition, in order to ensure that the edge saw teeth of the saw blade can be pressed on the branches under pressure when the saw blade saws the branches, and ensure that the reciprocating action of the saw blade is effective, the reciprocating mechanism is also in driving connection with a swinging mechanism 1000, and when the saw blade saws the branches, a worker drives the saw blade on the reciprocating mechanism to press on the branches through the swinging mechanism.

As an energy source of the reciprocator, a battery 1200 capable of repeatedly charging and discharging is mounted on the arm beam 800 and electrically connected to the reciprocator 900.

In the above embodiment, to simplify the structure of the reciprocating mechanism and reduce the weight of the reciprocating mechanism as much as possible, the reciprocating mechanism 900 specifically includes a motor 910 having a coaxially extending rod portion at one end, and the rod portion is rotatably connected to the swing mechanism 1000 capable of driving the beam arm 800 to rotate after passing through the rod portion. In addition, a first gear 920 is coaxially installed on the output shaft of the motor, two rotating shafts 980 are rotatably arranged on two sides of the first gear, and a second gear 970 is coaxially installed on the rotating shafts 980 and is in meshed connection with the first gear, so that the first gear can drive the rotating shafts connected with the first gear to rotate. Meanwhile, a half gear 930 is coaxially arranged on the rotating shaft, a rack 940 is further arranged between the two half gears 930, and the two half gears are in engagement with the rack in turn in the rotating process, so that the rack moves up and down in a reciprocating mode under the action of the two half gears. It should be noted that the saw blade 700 is connected to the rack to achieve synchronous movement with the rack. In addition, in order to maintain the stability of the rack in the moving direction, a piece of guide plate 960 is further arranged at the end parts of the two rotating shafts, specifically, the end parts of the two rotating shafts are rotatably inserted into the guide plate, and a sliding groove is further formed in the guide plate, a sliding rail 950 is slidably arranged in the sliding groove, and the sliding rail is fixedly connected with the rack, so that the rack can only slide up and down along the direction constrained by the sliding rail.

In addition, when the thicker branch is sawn off, in order to stably clamp the holding strip on the branch during sawing, the burden of holding by hand is reduced, and a binding band 300 is further arranged at the lower end of the extension rod 100, one surface of the binding band is a hook surface of a magic tape, the other surface of the binding band is a rough surface of a magic tape, and after the holding strip is clamped on the branch, the binding band is wound on the holding part of the L-shaped handle 230 so as to prevent the L-shaped handle from rotating to cause the holding strip to be loosened from the branch.

Finally, in this embodiment, in order to facilitate pruning of the branches and leaves and to facilitate withdrawal of the clip strip from the limbs, i.e. the two handles can be released by themselves, a return spring 1100 is further provided between the two handles 400. When the handles lose the acting force from the traction mechanism, the two handles are separated by themselves under the action of the return spring.

Working principle: the scheme has two working states, namely, one of the working states is to trim thinner branches and leaves, and only the blade is required to be arranged on the handle. During trimming, the L-shaped handle in the pulling mechanism is held to pull the first pulling rope, and the two handles are folded along with the action of the first pulling rope, so that the two blades are driven to trim branches and leaves. And in the second state, thicker branches are trimmed, specifically, the clamping strip replacing blade capable of clamping the branches is firstly arranged on the handle, then the clamping strip is used for clamping the branches through the pulling mechanism, and then the L-shaped handle in the pulling mechanism is tied through the binding belt, so that the clamping strip is prevented from loosening when the branches are sawn. Meanwhile, a beam arm is further arranged on the handle, a reciprocating mechanism is arranged on the beam arm, when thicker branches are cut, a motor in the reciprocating mechanism acts, the two half gears are driven to rotate through rotation, and along with the fact that the two half gears act on the rack in turn, the rack can drive a saw blade connected with the rack to conduct reciprocating sawing action. Meanwhile, when a worker drives the saw blade to press the surface of the branch through the swinging mechanism so as to make the reciprocating saw, the saw cutting operation can be implemented on the branch.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
