Abstract
A branch shear is provided, which comprises a mutually pivoted first shear component, a second shear component and an offsetting spring acted on the two shear components. The first shear component comprises a first shear blade and a first handle connected with the first shear blade; the second shear component is composed of a second shear blade and a second handle connected with the second shear blade; the two shear components are provided with a pivoting part at the connecting section between the shear blades and the handles. The shear is characterized in that: the pivoting part is provided with a spring containing space and the offsetting spring is arranged inside the spring containing space and also acts on the two shear components. The utility model features simple structure and convenient utilization and has highly stable and safe offsetting spring.
Description
Technical field
The present invention relates to a kind of branch cuts.
Background technology
Existing branch is cut, and comprises the first scissors assembly, the second scissors assembly of mutual pivot joint, back-moving spring.The first scissors assembly includes first shear blade and the handle that is connected with it, and second cuts assembly comprises second shear blade and the handle that is attached thereto, and back-moving spring is then outer to be located between two handles, reaches the function that scissors is opened reset.But in use there are many defectives in the scissors of this kind structure, because of back-moving spring is located at outward between two handles, so this back-moving spring very easily crushes user's hand; Secondly, the back-moving spring elastic instability of peripheral hardware, safety is low, and spring is easy to fly bomb and goes out in discontinuity, as easy as rolling off a log injure user or other people, thus threaten to personal safety; In addition, when shearing branch in putting in the branch clump, back-moving spring can be run into branch at any time and come off poor stability.
Summary of the invention
The object of the present invention is to provide a kind of back-moving spring be provided with rationally, simple, branch easy to use, safe is cut.
A kind of branch is cut, the first scissors assembly that comprises mutual pivot joint, the second scissors assembly and act on the first scissors assembly and the second scissors assembly on back-moving spring, the first scissors assembly includes first shear blade and the first handle that is connected with it, second cuts assembly comprises second shear blade and the second handle that is attached thereto, first, the connecting portion of two scissors assemblies between shear blade and handle is provided with the articulated section, it is characterized in that: be provided with a spring accommodation space in the described pivot part, described back-moving spring is located in the spring accommodation space of pivot part, and acts on first, on the two scissors assemblies.
This kind branch shear structure is simple, easy to use, compare with the prior art that back-moving spring is located at outward between two scissors handles, be built in because of its back-moving spring in the spring accommodation space of pivot part, so the situation that is crushed by spring or come off because of the spring that is collided can not occur pointing, its back-moving spring elastic stability, safe.
As a kind of improvement of such scheme, have on first connecting portion of the first scissors assembly as the pivot hole of pivot part to wear for pivot, it is the fan groove in the center of circle with the pivot hole that the described first connecting portion inboard is provided with a locating slot and one; Described back-moving spring is a torque spring, is placed in the pivot hole, and torque spring one end is embedded in described locating slot, and the other end places in the fan groove and is provided with the section of extending axially and inserts second shear blade.
Further improvement as such scheme, the pivot hole of this first connecting portion is stepped, be divided into macropore section and aperture section in the inner part in the outer part vertically, described torque spring is arranged on the macropore section in pivot hole, and is separated with a pivot barrel mutually between torque spring and pivot.
The side of above-mentioned described second shear blade in its pivot hole is provided with a circular hole and inserts for the section of extending axially of torque spring.

Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and embodiment.
Embodiment one: as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of branch is cut, comprise the first scissors assembly, the second scissors assembly of mutual pivot joint and act on the first scissors assembly and the second scissors assembly on as the torque spring 5 of back-moving spring, the first scissors assembly includes first shear blade 1 and is attached thereto the first handle 2 that connects, and these first handle 2 front ends are provided with first connecting portion 6 and are embedded for first shear blade 1; Second cuts assembly comprises second shear blade 3 and the second handle 4 that is attached thereto, and these second handle 4 front ends are provided with second connecting portion 15 and are embedded for second shear blade 3; The side of second shear blade 3 in its pivot hole 31 is provided with a circular hole 11, and these second handle 4 front ends are provided with second connecting portion 15 and are embedded for second shear blade 3; This each shear blade is provided with pivot hole and this each connecting portion and is provided with the pivot hole and wears for pivot 14 as pivot part, the pivot hole 7 of this first connecting portion 6 is divided into macropore section and aperture section in the inner part in the outer part vertically, stepped, it is the fan groove 8 in the center of circle with pivot hole 7 that the described first connecting portion inboard is provided with a locating slot 9 that is communicated with pivot hole 7 and one; Described torque spring 5 is placed in the macropore section in pivot hole 7, and the macropore section in pivot hole 7 is built-in with a pivot barrel 12 and wears for pivots 14, and torque spring 5 and pivot are isolated, and prevents the torque spring wearing and tearing.Torque spring 5 one ends are embedded in described locating slot 9, the other end places in the fan groove 8 and is provided with the section of extending axially 10 that the circular hole 11 with second shear blade 3 is complementary, during installation, this circular hole 11 is inserted in this extension 10, so when first shear blade 1 was embedded on this first connecting portion 6, except this section of extending axially 10, the main part of this torque spring 5 was limited in the macropore section in pivot hole 7, can not do axial moving, can not be subjected to the collision of outside object yet.
As Fig. 5, shown in Figure 6, during use, first and second shear blade is that relative motion is done in the axle center with pivot 14, when first and second shear blade is sheared closure mutually, torque spring 5 in the fan groove 8 at pivot part 6 under the drive of second shear blade 3 by the elasticity turn-knob, thereby obtain a reseting elasticity; After shearing finished, second shear blade 3 made first and second shear blade keep original open state under the reseting elasticity effect of torque spring 5 and open, and fan groove 8 plays the restriction angle that torque spring reverses that resets.
