as shown in fig. 1, the strong pruning shears of the present embodiment include a first shear member 1 and a second shear member 2, wherein the first shear member 1 has a first handle 11 and a main blade 12; the second scissor element 2 has a second handle 21 and a secondary blade 22; the first scissors member 1 and the second scissors member 2 are rotatably connected to form scissors.

As shown in fig. 2, the scissor aid 3 is arc-shaped and has an arc-shaped inner side wall 30 adapted to fit over the outer wall of the main blade 12, and a smooth outer arc surface 33, and has a first end 31 rotatably connected to the distal end of the main blade 12, and a second end 32 opposite to the first end 31; the first end 31 of the scissor aid 3 is connected to the side of the primary blade 12 remote from the secondary blade 22.

As shown in fig. 5 to 6, the auxiliary stopper 4 is installed at the end of the auxiliary blade 22, and protrudes outward from the outer wall of the side of the auxiliary blade 22 facing the main blade 12 by a length greater than the width of the outer arc surface 33 of the scissors auxiliary 3.

When the first and second scissors members 1, 2 are opened to a maximum, the second end 32 of the scissor assist 3 is able to pass over the assist stop 4 as the first end 31 of the scissor assist 3 rotates about the mounting point with the main blade 12.

Referring to fig. 3, 4 and 6, when cutting some thicker branches or harder branches, the strong pruning shears according to this embodiment firstly rotates the auxiliary shears 3 outwards, opens the opening between the first shears 1 and the second shears 2, then rotates the auxiliary shears 3 inwards after the branches are sent into the opening, to the inner side of the auxiliary barrier 4, then forces to close the first shears 1 and the second shears 2, the auxiliary shears 3 gradually move to the inner side of the auxiliary barrier 4 in the process of following the downward movement of the first shears 1, and at this time the outer arc surface 33 is in contact with the auxiliary barrier 4, so that the branches are enclosed in the enclosed space formed by the enclosing of the main blades 12, the auxiliary blades 22 and the auxiliary shears 3, and at this time the first shears 1 and the second shears 2 can be pressed by the force without worrying about slipping; when the branches slide to the position contacted with the scissors auxiliary piece 3, the first scissors piece 1 and the second scissors piece 2 are pressed by the force, and the branches are supported against the scissors auxiliary piece 3 from the rear, so that the force is better applied, and the branches are more easily sheared.

Preferably, when the first and second scissors members 1 and 2 are closed, the distal end of the primary blade 12 is inboard of the position of the secondary blade 22 where the secondary barrier 4 is mounted. By the design, when the branches are cut, the main blade 12 can be easily cut to the bottom, and the use habit of the conventional scissors is better met.

In this embodiment, the scissor aid 3 is detachably mounted on the main blade 12; the auxiliary barrier 4 is detachably mounted on the auxiliary blade 22. The powerful pruning shears of the embodiment can select different functions according to specific application scenes; if the branches needing to be sheared are mostly easier, the auxiliary scissors member 3 and the auxiliary blocking member 4 can be taken off from the main blade 12 and the auxiliary blade 22 respectively, so that the use is lighter; if a plurality of branches needing to be cut are difficult to cut, the auxiliary scissors member 3 and the auxiliary blocking member 4 can be respectively arranged on the main blade 12 and the auxiliary blade 22, so that the branches which are difficult to cut at ordinary times can be easily cut.

Specifically, as shown in fig. 3, the first end 31 of the scissors auxiliary 3 is provided with a first through hole 35, the end of the main blade 12 is provided with a second through hole 13, and the scissors auxiliary 3 is mounted on the main blade 12 by passing through the first through hole 35 and the second through hole 13 by using a first connecting shaft (not shown in the figure).

As shown in fig. 3, 5 and 6, the near end of the auxiliary blade 22 is provided with a third through hole 23; the auxiliary stopper 4 has a shaft 41, a retainer ring 42 provided on the shaft 41, and an external thread provided outside the retainer ring 42; after the auxiliary blocking member 4 penetrates into the third through hole 23, the retainer ring 42 is located at one side of the third through hole 23, and an external thread is provided on a shaft rod portion penetrating out of the third through hole 23, and the auxiliary blocking member 4 is fastened to the auxiliary blade 22 by using the nut 43.

Preferably, as shown in fig. 2, the inner arc surface of the scissors auxiliary 3 is provided with a saw tooth structure 34. When the strong pruning shears of the present embodiment are used to cut off the branches, the branches slide to a position contacting with the shears auxiliary member 3 and then are snapped by the saw tooth structure 34, and when the first shears member 1 and the second shears member 2 are pressed by the force, the shears auxiliary member 3 drives the snapped branches to rotate in the downward movement process, so that the branches rotate relative to the main blade 12, and the branches can be easily cut off.

Preferably, as shown in fig. 2, 7 and 8, the second end 32 of the scissors auxiliary member 3 is provided with a fourth through hole 36, and the auxiliary blade 22 is provided with a threaded hole 24; the first through hole 35 provided at the first end 31 of the scissors auxiliary member 3 can be opposite to the third through hole 23 provided at the auxiliary blade 22 and fixedly connected through the auxiliary blocking member 4; a fourth through hole 36 provided at the second end 32 of the scissor aid 3, capable of being fixedly connected by bolts with the screw hole 24 provided on the auxiliary blade 22; after the scissor aid 3 is fixed to the auxiliary blade 22, the serrated structure 34 is raised above the auxiliary blade 22.

This adds a function to the strong pruning shears of the present embodiment, and when the branches to be cut are not particularly difficult, in this way, when the branches are fed between the main blade 12 and the auxiliary blade 22, the first shears member 1 and the second shears member 2 are forced to press, so that the branches are snapped by the saw tooth structure 34 and are not easy to fall off, thereby facilitating the cutting of the branches.

In this embodiment, as shown in fig. 9, the first through hole 35 of the first end 31 of the scissors auxiliary member 3 is detachably installed by the auxiliary blocking member 4 reversely installed at the position of the third through hole 23 of the auxiliary blade 22. Therefore, the existing parts can be fully utilized, and the number of the parts is reduced as much as possible.

The scissors auxiliary member 3 is mounted on the auxiliary blade 22 through the auxiliary blocking member 4 as an auxiliary member for separating the branches, which adds a function to the strong pruning scissors of the present embodiment; when the branches grow densely, the branches needing to be sheared can be separated from the branches not needing to be sheared by using the scissors auxiliary piece 3, so that the method is very convenient, and is particularly convenient when some branches with thorns are treated.

As shown in fig. 8, the power spring 5 is further included between the first handle 11 and the second handle 21. The strong spring 5 is used for externally supporting the first scissors member 1 and the second scissors member 2, and after the first scissors member 1 and the second scissors member 2 are pressed by the application of force to be closed and cut off the branches, the strong spring 5 can exert force to externally support the first scissors member 1 and the second scissors member 2, so that the first scissors member 1 and the second scissors member 2 are restored to the state before being pressed, and the use is more convenient.

Also comprises a fifth through hole 6 arranged at the tail ends of the first handle 11 and the second handle 21, and a tool bag hung on the fifth through hole 6 by using a hanging rope. When the scissors auxiliary member 3 and the auxiliary stopper 4 are not required to be used, they can be put into a small tool pack (such as a small cloth pack) and hung at the position of the fifth through hole 6.
