CN2830016Y - Power saving heavy shears - Google Patents

Abstract

The utility model relates to a pair of power saving heavy shears, which comprises two plastic handgrips, two shear blades and a fixed axis, wherein the two shear blades are respectively assembled on the two plastic handgrips and the two shear blades are hinged through the fixed axis. A spring and a spring locking mechanism are arranged at the inner side between the two plastic handgrips. When the utility model is used, first, the spring locking mechanism is opened, the pair of shears automatically opens under the action of the spring, then, a sheared product is clamped by the two opened shear blades and a user can shear the sheared product by forcibly holding the two plastic handgrips. Then, a shearing action is completed. If the next shearing action is conducted, the user stops applying grasp force to the two plastic handgrips, and at the time, the two shear blades automatically open by the elasticity tension when the spring is in the process of the recovering to an original state. Thus, the step that the user need separate the two shear blades by force at the beginning is omitted and the use is very laborsaving and convenient.

Description

The heavy scissors in a kind of labour-saving

Technical field

The utility model relates to a kind of scissors.

Background technology

Scissors is a kind of device that is used for specially shearing as the paper analog, and its integral body of traditional scissors is made of last plastic handgrip, last shear blade, following plastic handgrip, lower scissors sheet and fixed axis.During use, the user grasps upper and lower plastic handgrip, and firmly separates them, after allowing its upper and lower shear blade that is " Y " font that separates block then to be cut thing, the user firmly holds upper and lower plastic handgrip again, when upper and lower shear blade closes up fully, has promptly finished being cut the shearing of thing.The scissors of the type comparatively speaking, its weak point is: in the process of using, need artificial firmly separately it, make troubles to the user.In addition, traditional scissors function singleness, in use as run into and has needed to order or during boundary's paper, the instrument that the needs use is other is also made troubles to the user.

The utility model content

The purpose of this utility model is to provide a kind of use labour-saving multipurpose heavy scissors.

The heavy scissors in a kind of labour-saving that the utility model provides comprises two plastic handgrips, two shear blades and fixed axis, and two shear blades are assemblied in respectively on two plastic handgrips, and two shear blades form hinged by fixed axis; Inboard between described two plastic handgrips is provided with a spring and snap lock mechanism, and an end of described spring is fixed on the inboard of a plastic handgrip, and the other end of spring is fixed on the inboard of another plastic handgrip; Described snap lock mechanism is made up of snap close and two guide rails, wherein whole process is provided with lock seaming on guide rail, another guide rail top is provided with lock seaming, article two, guide rail is separately positioned on the inboard of two plastic handgrips, the cross section of described snap close is " worker " font, one side assembly of snap close is provided with in whole process on the guide rail of lock seaming, and the opposite side assembly of snap close is provided with on the guide rail of lock seaming in part, and snap close can move around along two guide rails.

When the utility model uses, at first open snap lock mechanism, being about to snap close laterally passes and makes a side of snap close break away from part to be provided with lock seaming on the guide rail of lock seaming, and the opposite side of snap close still assembly be provided with on the guide rail of lock seaming in whole process, at this moment scissors opens under the effect of spring automatically, after allowing open two shear blades block then to be cut thing, the user firmly holds two plastic handgrips again and can shear being cut thing, finish a shear action this moment, if in the time of will carrying out next shear action, the user stops two plastic handgrips are applied grip, this moment, two shear blades were replied in the process of reset condition at spring, be subjected to its elasticity tension and automatically separately, thus saved the user beginning with regard to the time just need firmly separately this step of two shear blades, very easy to use.When not using, snap close can be locked snap lock mechanism again and ensures the safe in utilization of scissors toward pushing back.

As a kind of embodiment of the present utility model, the inboard of described two plastic handgrips is respectively equipped with a projection, and the two ends of spring are separately fixed on two projections.

The wherein tail end of a plastic handgrip described in the utility model is provided with a Nail nipper, and the tail end of another plastic handgrip is provided with a blade, to adapt to different use occasions.

Compare with traditional scissors, the utlity model has rapid operation, characteristics such as easy-to-use, of many uses, be particularly suitable for large-sized object is sheared.

The utility model will be further described below in conjunction with the drawings and the specific embodiments.
