Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1 to 3, the utility model comprises a vertical support rod 1, a first sleeve 2 is detachably sleeved on the upper end of the support rod 1, a scissors 3 is mounted on the first sleeve 2, the hinge point of the scissors 3 is fixed on the first sleeve 2, a vertical first through groove 4 is arranged on the first sleeve 2, a first slider 5 capable of moving up and down along the first through groove 4 is arranged in the first through groove 4, two connecting rods 6 are hinged on the first slider 5, and the upper ends of the two connecting rods 6 are respectively hinged with the two lower ends of the scissors 3; the outer edge surface of the first sleeve 2 is provided with vertical sawteeth 7;

a second sleeve 8 can be detachably sleeved on the support rod 1, a vertical second sliding groove 9 is formed in the second sleeve 8, a second sliding block 10 capable of moving up and down along the second sliding groove 9 is arranged in the second sliding groove 9, a pressure rod 11 is hinged above the second sleeve 8, a push rod 12 is hinged to the middle of the pressure rod 11, and the other end of the push rod 12 is hinged to the second sliding block 10; a steel wire rope 13 is connected between the first slide block 5 and the second slide block 10.

For the installation of better realization scissors 3, the upper end of first sleeve 2 for seal the form, install montant 14 on the up end of first sleeve 2, the round pin axle of 3 pin joints of scissors is fixed on montant 14.

In order to realize reset, a pressure spring 15 is connected between the left handle and the right handle of the scissors 3.

In order to adapt to different heights, the height of the support rod 1 and the length of the steel wire rope 13 have various specifications.

In order to fix the first sleeve 2, the second sleeve 8 and the support rod 1, through holes are formed in the first sleeve 2 and the second sleeve 8, and screws 16 matched with the support rod 1 are screwed in the through holes.

In order to keep the two blades of the scissors 3 in a contracted state when the scissors are not used, the pressing rod 11 is hinged with a connecting plate 17, the connecting plate 17 is provided with a bayonet 18, and the bayonet 18 can be clamped on the screw 16 of the second sleeve 8.

In order to facilitate the opening of the first sliding groove or the second sliding groove 9, a protrusion is arranged on the first sleeve 2 or the second sleeve 8 at the position where the sliding groove is opened.

The utility model discloses during the use, at first can select the length of the bracing piece 1 of suitable length as required, then use screw 16 to fix first sleeve 2 on bracing piece 1, use screw 16 to fix the lower extreme at bracing piece 1 with second sleeve 8 simultaneously, later use wire rope 13, link together first slider 5 and second slider 10 to keep wire rope 13 to be in the state of flare-outing, wire rope 13 of unnecessary length can cut.

The supporting rods 1 with different lengths can be adapted to different tree species; for some lower tree species, the shorter supporting rod 1 is adopted, so that the operation is convenient, and the use of the whole tool is convenient; for some tall trees, the longer support rods 1 can be used directly for operation.

When actually pruning, at first place the branch that needs to prune in the middle of two cutting edges of scissors 3, then press and move depression bar 11, depression bar 11 can extrude push rod 12 this moment, make push rod 12 promote second slider 10 and move down along second spout 9, because be connected with wire rope 13 between second slider 10 and the first slider 5, consequently second slider 10 can pass through wire rope 13 and stimulate first slider 5 and descend, after first slider 5 descends, through connecting rod 6's effect, shrink behind the lower extreme of scissors 3, thereby make the upper end of scissors 3 also shrink together, prune the branch.

As the long pressing rod 11 is adopted, the pressing rod 11 can play a role of a lever, when the pressing rod is pressed, a labor-saving role can be played, and then the branches are cut by the scissors 3 through the pulling of the steel wire rope 13.

When cutting is not needed, the pressing rod 11 is released, and at the moment, the scissors 3 can return to the initial opening state and the pressing rod 11 can also return to the non-pressed state due to the fact that the compression spring 15 is connected between the left handle and the right handle of the scissors 3.

When thick branches are encountered and the branches are difficult to cut by the scissors 3, the pressure lever 11 can be pressed at first, the connecting plate 17 on the pressure lever 11 is supported, and the bayonet 18 on the connecting plate 17 is clamped on the screw 16 on the second sleeve 8; at the moment, the scissors 3 are kept in a closed state, and then the thick vertical part is directly sawn by using the saw teeth 7, so that the thick vertical part is cut off.

This device is through setting up two parts about to can be adapted to the bracing piece 1 of different length, the bracing piece 1 of different length is selected as required by the user of being convenient for by oneself, and after 1 fracture of bracing piece, can change by oneself, bracing piece 1 can the selective purchase simultaneously, reduces user's cost.

The device realizes the purpose of labor saving by arranging the pressure lever 11 and utilizing the lever principle, and is favorable for cutting thicker or harder branches.

This device can utilize scissors 3 to tailor thinner branch through setting up sawtooth 7 on the one hand, and on the other hand can utilize sawtooth 7 to saw thicker branch to the branch pruning of all kinds of thicknesses has been realized.

The utility model discloses convenient operation, the structure is ingenious, low cost, and it is convenient to make, and is safe effective, can prune not co-altitude, all kinds of branches of different thicknesses, has improved pruning speed, and the instrument is convenient for maintain.
