Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a safety scissors, including handle shell 1, metal framework 2, first screw 3, torsional spring 4, open angle spacer pin 5, safety lock catch connection hole 6, gasket 7, second screw 8, nut 9 and blade 10, handle shell 1's inboard is provided with metal framework 2, and metal framework 2's the outside is connected with handle shell 1 through first screw 3, be provided with torsional spring 4 between metal framework 2 and open angle spacer pin 5, and open the upside that angle spacer pin 5 is located

torsional spring

4, 2 lower extremes of metal framework are provided with safety lock catch connection hole 6, install second screw 8 and nut 9 on the handle shell 1, and be provided with gasket 7 between second screw 8 and nut 9 and the handle shell 1, metal framework 2's upper end is provided with blade 10.

The metal framework 2, the safety lock buckle connecting hole 6 and the blade 10 are of an integrated structure, and the stability of the overall use of the scissors is guaranteed.

Metal framework 2 constitutes through first screw 3 and handle shell 1 between can dismantle the connection, and the safety lock detain connection hole 6 at 2 both ends of metal framework and blade 10 all extend the outside of handle shell 1 to handle shell 1 is high strength engineering plastics, can conveniently maintain the change work to the blade 10 of this scissors, has improved the normal performance of this scissors, also can guarantee the normal user state of safety lock detain connection hole 6 and blade 10 simultaneously.

The both ends that open angle spacer pin 5 all imbed metal skeleton 2's inside, and open between angle spacer pin 5's one end and the metal skeleton 2 be fixed connection to open between angle spacer pin 5's the other end and the metal skeleton 2 be swing joint, can be through opening the effectual activity angle scope of injecing between two metal skeleton 2 of angle spacer pin 5, thereby can guarantee the normal state of opening and shutting between the metal skeleton 2.

The second screw 8 runs through handle shell 1, metal framework 2 and torsional spring 4, and the both sides of torsional spring 4 are connected with handle shell 1, can guarantee the holistic stable operating condition of this scissors, can guarantee the state that opens and shuts of this scissors efficient.

The front end of the blade 10 is of a flat structure, so that the safety performance of the scissors can be further enhanced.

The working principle is as follows: when the safety scissors are used, firstly, according to the figures 1-4, the assembly work of the scissors is required to be completed, the metal framework 2 can be fixed on the handle shell 1 through the first screw 3, the fixed state of the metal framework 2 can be ensured to be stable and safe because the first screw 3 is a hexagon socket head disassembly-preventing screw, and the safety lock buckle connecting holes 6 and the blades 10 at the two ends of the metal framework 2 completely extend out of the handle shell 1 when the metal framework 2 is fixed;

after the two metal frameworks 2 are respectively fixed on two different handle shells 1, a torsion spring 4 and an opening angle limiting pin 5 are arranged between the two metal frameworks 2, the two metal frameworks 2 are enabled to carry the handle shells 1 together, and finally, a second screw 8 penetrates through the handle shells 1, the metal frameworks 2 and the torsion spring 4 and is connected to a nut 9, so that the 2 handle shells 1 can be fixed together through the second screw 8 and the nut 9, and the assembling work of the scissors is completed;

after the scissors are assembled, if the scissors are required to be used, the front end of the handle shell 1 can be pinched by hands, 2 handle shells 1 are extruded, the metal framework 2 on the inner side of the handle shell 1 is opened and closed, when the front end of the handle shell 1 is pressed, because the torsional spring 4 and the opening angle limiting pin 5 are arranged between the metal frameworks 2, the unfolding state of the metal framework 2 can be recovered through the torsional spring 4, and the unfolding angle between the metal frameworks 2 is limited through the opening angle limiting pin 5, so that the blades 10 at the ends of the metal frameworks 2 can be efficiently opened and closed, meanwhile, in the using process of the scissors, the scissors can be fixed at a designated position through the connection of the safety lock buckle connection hole 6 and the outside, so that the scissors cannot be lost and can be controlled in the using moving range, and the two blades 10 of the fixed scissors are also in the state of being not separately detachable, the safety use of the scissors is ensured, the using process of the scissors is completed, and the content which is not described in detail in the specification belongs to the prior art which is known by the professional in the field.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
