Description

Pruning shears

Technical Field

The utility model belongs to the technical field of garden instrument, concretely relates to pruning shear.

Background

Gardens pruning scissors are used for pruning the branch, and its scissors part divide into big fan blade and little fan blade, and the general big fan blade cutting edge of current pruning scissors is the arc, and the back of a knife part is the linear type, and little fan blade cutting edge also is the arc, and its arc top is the radian that R is 40mm circle corresponds, as shown in figure 1, during the pruning, the branch is arranged in two curved cutting edges and is rotated and cut. However, in practical application, the pruning shears are relatively laborious, and the cutting edges are all arc-shaped, so that the pruning shears are not easy to use and operate. In addition, the locking hook is only arranged at the tail of the cutter handle of the existing pruning shears, and the handle of the scissors is locked and closed through the locking hook when the pruning shears are not used, so that the scissors are locked and fixed. However, in practice, the locking hook is easy to fall off, so that the cutting edge of the scissors is opened, people are easy to hurt, and the scissors are easy to damage.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a pruning shear, this pruning shear establishes big fan blade cutting edge to straight sword, and little fan blade radian reduces, realizes the laborsaving purpose of pruning, sets up the locking buckle in addition at scissors handle shoulder, realizes the purpose of the closed dual fail-safe of scissors.

The utility model adopts the following technical scheme:

the utility model provides a pruning scissors, the big blade of scissors, the little blade of scissors are through locking screwed connection, are equipped with the spring between its big blade of scissors handle, the little blade of scissors handle, and the afterbody of scissors handle is equipped with annular locking couple, can be fixed with scissors locking, the cutting edge part of big blade of scissors is straight sword, and the back of a knife part is the arc, little blade of scissors cutting edge root is the arc, and R is 24mm, and the front portion is the straight line.

Furthermore, the shoulder of the small-blade scissors handle is provided with a locking buckle, and the locking buckle can close and lock the scissors blades.

Further, the locking buckle is U-shaped, and its inside transversely is equipped with the horizontal pole, the spout has been seted up at the shoulder of little fan shear blade scissors handle, the horizontal pole is arranged in the spout and is slided, big fan shear blade tail end has been seted up and has been locked the recess, and its tail end side edge system has the outstanding fin of locking, the horizontal pole promotes the back and arranges in the locking recess, locks fixed scissors blade.

Furthermore, a sliding groove and a protrusion which are matched with each other are formed below the shoulder part of the small-blade scissors handle relative to the sliding surface.

Furthermore, the side edge of the locking buckle is provided with a bulge which is convenient for pushing and pulling.

The utility model discloses an advantage and effect do:

1. the utility model discloses change the cutting edge shape of conventional pruning scissors, establish big fan blade into straight sword, the back of the knife blade is the arc, and the radian of little fan blade is less than the radian of current pruning scissors little fan blade, and through many times experimental, the utility model discloses pruning scissors is more laborsaving than current pruning scissors, and well operation.

2. The utility model discloses a set up the locking buckle at scissors handle shoulder, the annular locking couple of cooperation handle afterbody realizes the closed purpose of dual guarantee scissors locking, makes the use of scissors and deposits safelyr, reduces the scissors damage.

Detailed Description

Example 1

The utility model provides a pruning scissors, pruning scissors includes big scissors piece 1, little scissors piece 2, locking screw 3, big scissors piece scissors handle 4, little scissors piece scissors handle 5, spring 6, annular locking couple 7, locking buckle 8, spout 9, horizontal pole 10, locking outstanding fin 11, locking recess 12.

The big shear blade 1 and the small shear blade 2 of the pruning shear are connected through the locking screw 3, the spring 6 is arranged between the big shear blade scissor handle 4 and the small shear blade scissor handle 5, and the setting mode of the spring is the prior art. The afterbody of scissors handle is equipped with annular locking couple 7, and another scissors handle afterbody corresponds position department and is equipped with the recess, and 7 cards of annular locking couple realize closed locking fixed scissors in the recess that another handle corresponds, the cutting edge part of big fan shear blade 1 is straight sword, and the back of the knife blade part is the arc, little fan shear blade cutting edge root is the arc, and R is 24mm, and anterior radian is small, is close the straight line.

Little fan blade scissor handle 5's shoulder is equipped with locking buckle 8, locking buckle 8 is the U style of calligraphy, and its inside transverse welding has horizontal pole 10, spout 9 has been seted up to little fan blade scissor handle 5's shoulder, horizontal pole 10 is arranged in spout 9 and is slided, locking recess 12 has been seted up to 1 tail end of big fan blade, and its tail end side edge system has the outstanding fin 11 of locking, arrange locking recess 12 in behind the horizontal pole 10 promotion, the fixed scissors blade of locking.
