It has a tall stem, branches with short spines, small leaflets as leaves, the leaves are opposite and sessile. The inflorescence is terminal or axillary; the perianth segments are yellowish green and are roughly the same in shape and size; few female flowers have developed stamens, and pruning shears are used when pruning the branches and leaves of Chinese prickly ash;

[0003] Existing Chinese prickly ash pruning shears are mostly used by manually holding them. However, the manual holding method will cause certain limitations in the use of Chinese prickly ash pruning shears. Since the Chinese prickly ash pruning shears themselves do not have a telescopic structure, the branches and leaves located at high positions cannot be effectively pruned, which affects the subsequent normal growth of Chinese prickly ash, reduces the production capacity, and the overall practicality of the Chinese prickly ash pruning shears is poor. Content of the Utility Model

An auxiliary slide plate 16 is sleeved on the outer side of one end of the lock rod 15;

[0022] In use, adjust the extension length between the fixed sleeve 3, the extension sleeve 6 and the extension rod 5 according to the actual usage requirements. Then, use the provided locking rod 15 to position the sleeve. After positioning, the pruning shears can be held manually, which is convenient for subsequent pruning of Chinese prickly ash. During pruning, the operation of the second motor 11 causes the pruning head 12 connected to its output end to move, which facilitates subsequent pruning of Chinese prickly ash. When the first motor 9 operates, it rotates the rotating seat 10, and the rotation of the rotating seat 10 is used to adjust the orientation of the pruning head 12, which is convenient for better subsequent pruning of Chinese prickly ash;

[0023] As a further implementation manner of this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, it includes a handle 1. An anti-slip pad 2 is sleeved on the outer surface of the handle 1. A fixed sleeve 3 is distributed above the handle 1. A clamping seat 4 is provided at the top end of the fixed sleeve 3. One end of the clamping seat 4 is fixedly installed with an extension rod 5. An extension sleeve 6 is sleeved on the outer surface of the extension rod 5. A slide rail 7 is provided on the inner side wall of the extension sleeve 6. A locking hole 8 is formed on the surface of the extension sleeve 6. A pruning structure is provided at the top end of the extension sleeve 6. A chute 13 is formed on the side wall of the extension rod 5. One end of the extension rod 5 is fixedly connected with a return spring 14 inside, and the other end of the return spring 14 is fixedly connected with a locking rod 15. The locking rod 15 is slidably connected with the extension rod 5 through the return spring 14, and the locking rods 15 are symmetrically distributed on both sides of the extension rod 5. An auxiliary sliding plate 16 is sleeved on the outer side of one end of the locking rod 15. A cross groove 17 is formed in the middle of the bottom end of the fixed sleeve 3. A through hole 18 is formed on the outer periphery of the bottom of the fixed sleeve 3. The through holes 18 are equidistantly distributed along the center point of the fixed sleeve 3, and the through holes 18 and the fixed sleeve 3 form an integral structure. A cross clamping block 19 is fixedly installed in the middle of the top end of the handle 1, and a connecting bolt 20 is provided on the side wall of the cross clamping block 19;

[0024] In use, first insert the cross-shaped clamping block 19 provided in the middle of the top end of the handle 1 into the inner side of the cross-shaped groove 17 opened at the bottom of the fixed sleeve 3. Then, pass the connecting bolt 20 through the inner side of the through hole 18 and extend it into the bolt groove opened on the side wall of the cross-shaped clamping block 19. Then, turn the connecting bolt 20 to achieve a stable connection between the handle 1 and the fixed sleeve 3. Then, pull the clamping seat 4 to drive the extension rod 5 fixedly installed at its bottom to slide inside the fixed sleeve 3. When the extension rod 5 slides, it will slide along the slide rail 7 through the slide groove 13 opened on its side wall, so as to improve the stability of the extension rod 5 during the sliding process. When the extension rod 5 extends to a certain position, the reverse force generated by the deformation of the return spring 14 will push the locking rod 15, and then insert one end of the locking rod 15 into the locking hole 8 opened on the side wall of the fixed sleeve 3, thereby realizing the positioning between the fixed sleeve 3 and the extension rod 5. At this time, pull the extension sleeve 6 longitudinally to make it slide along another extension rod 5 provided at the top end of the clamping seat 4. When the position of the extension sleeve 6 is adjusted, similarly, the reverse force generated by the deformation of the return spring 14 fixedly connected to the inner side of one end of the other extension rod 5 will push the locking rod 15 in the reverse direction, so as to insert one end of the locking rod 15 into the locking hole 8 opened on the side wall of the extension sleeve 6, thereby realizing the positioning of the extension sleeve 6, so as to realize the adjustment of the length of the whole pruning shear;

[0025] Specific working principle:

[0026] First, insert the cross-shaped chuck 19 provided in the middle of the top end of the handle 1 into the inner side of the cross-shaped groove 17 opened at the bottom of the fixed sleeve 3. Then, make the connecting bolt 20 pass through the inner side of the through hole 18 and extend into the bolt groove opened on the side wall of the cross-shaped chuck 19. Immediately turn the connecting bolt 20 to achieve a stable connection between the handle 1 and the fixed sleeve 3. Then, pull the clamping seat 4 to drive the extension rod 5 fixedly installed at its bottom to slide inside the fixed sleeve 3. When the extension rod 5 slides, it will slide along the slide rail 7 through the slide groove 13 opened on its side wall, thereby improving the stability of the extension rod 5 during the sliding process. When the extension rod 5 extends to a certain position, the reverse force generated by the deformation of the return spring 14 will push the locking rod 15, and then input one end of the locking rod 15 into the locking hole 8 opened on the side wall of the fixed sleeve 3, thereby achieving the positioning between the fixed sleeve 3 and the extension rod 5. At this time, longitudinally pull the extension sleeve 6 to make it slide along another extension rod 5 provided at the top end of the clamping seat 4. When the position of the extension sleeve 6 is adjusted, similarly, the reverse force generated by the deformation of the return spring 14 fixedly connected to the inner side of one end of the other extension rod 5 will push the locking rod 15 in the reverse direction, so as to input one end of the locking rod 15 into the locking hole 8 opened on the side wall of the extension sleeve 6, thereby achieving the positioning process of the extension sleeve 6, so as to realize the adjustment of the length of the entire pruning shear. Subsequently, during pruning, the operation of the second motor 11 makes the pruning head 12 connected to its output end move, which can facilitate the subsequent pruning of the Chinese prickly ash. When the first motor 9 operates, it will rotate the rotating seat 10, so as to use the rotation of the rotating seat 10 to adjust the orientation of the pruning head 12, which is convenient for better subsequent pruning of the Chinese prickly ash.
