Problems solved by technology

However, scissors with this structure have many defects during use. Because the return spring is externally installed between the two handles, the return spring can easily pinch the user's hand; secondly, the return spring of the peripheral is unstable and safe. Low resistance, the spring is easy to fly out when the force is uneven, and it is very easy to injure the user or others, thereby posing a threat to personal safety; Falling off the branches, poor stability

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 [0001] The invention relates to a branch shears. Background technique [0002] The existing branch shears comprise a first scissors assembly, a second scissors assembly and a return spring pivotally connected to each other. The first scissors assembly includes a first scissors blade and a handle connected thereto, the second scissors assembly includes a second scissors blade and a handle connected thereto, and a return spring is externally arranged between the two handles to allow the scissors to open reset function. However, scissors with this structure have many defects during use. Because the return spring is externally installed between the two handles, the return spring can easily pinch the user's hand; secondly, the return spring of the peripheral is unstable and safe. Low resistance, the spring is easy to fly out when the force is uneven, which is very easy to injure the user or others, thus posing a threat to personal safety; It falls off the branc...
