[0014] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] Reference Figs. 1-3This embodiment is a prison-specific safety scissors, including a knife box 100 and two scissor blades 200. The knife box 100 includes an upper shell 101 and a lower shell 102. The interior of the upper shell 101 and lower shell 102 is recessed to form a blade mounting groove 103. The left and right sides of the mounting groove 103 communicate with the outside. A V-shaped notch 104 is formed above the middle of the upper shell 101 and lower shell 102. The two scissor blades 200 are crosswise arranged within the mounting groove 103. Insertion holes 201 are provided at the ends of the two scissor blades 200. A hinge shaft 105 is provided inside the 01. A cutting edge 202 is machined on one side of the scissor blade 200. An arc-shaped notch 203 is opened at the position below the cutting edge 202 of the scissor blade 200. A connecting shaft 106 is provided at the arc-shaped notch 203 of the two scissor blades 200. The two ends of the connecting shaft 106 are respectively connected to the upper housing 101 and the lower housing 102. A torsion spring 107 is sleeved on the outer wall of the connecting shaft 106. A connecting hole 204 is opened on the end face of the two scissor blades 200. The two ends of the torsion spring 107 are respectively engaged in the connecting hole 204 of the two scissor blades 200.

[0016] Two scissor blades 200 are placed in the mounting slots 103 of the upper housing 101 and the lower housing 102. Since the insertion holes 201 at the ends of the two scissor blades 200 are equipped with hinge pins 105, when the outer sides of the two scissor blades 200 are pressed, the two scissor blades 200 will rotate around the hinge pins 105, placing the material to be cut into the V-shaped notch 104. When the two scissor blades 200 rotate around the hinge pins 105, the cutting edges 202 of the two scissor blades 200 can cut the material. Yes, because the arc-shaped notches 203 of the two scissor blades 200 are equipped with torsion springs 107, and the two ends of the torsion springs 107 are respectively engaged in the connecting holes 204 of the two scissor blades 200, so when the two scissor blades 200 rotate around the hinge axis 105, they will be subjected to the elastic force of the torsion springs 107. After cutting, the operator releases the sides of the two scissor blades 200, and the two scissor blades 200 rotate in the opposite direction around the hinge axis 105 under the action of the elastic force of the torsion springs 107 to return to their original position.

[0017] In this embodiment, a thread-pulling groove 205 is provided on the outer side of the scissor blade 200.

[0018] The thread-picking groove 205 can be used for tasks such as thread removal. The thread-picking groove 205 on the side of the two scissor blades 200 is used to pick up the thread.

[0019] In this embodiment, an arc-shaped anti-stab head 206 is provided on the top of one side of the thread picking groove 205.

[0020] The curved anti-stab head 206 can prevent personal injury caused by exposed sharp parts and improve safety.

[0021] In this embodiment, the side walls of the upper shell 101 and the lower shell 102 are recessed inward to form a second notch 108.

[0022] When the outer sides of the two scissor blades 200 are squeezed, the two scissor blades 200 move toward the second notch 108, which provides space for the scissor blades 200 to move inward.

[0023] In this embodiment, a pressing plate 207 is installed on the sidewalls of the two scissor blades 200.

[0024] Because the scissor blades 200 are relatively thin, it is easy to get injured when pressing the outer side of the two scissor blades 200 with your fingers. Therefore, a pressing plate 207 is installed on the side wall of the two scissor blades 200. Pressing the pressing plate 207 will drive the two scissor blades 200 to rotate for cutting.

[0025] Working principle: Place the material to be cut into the V-shaped notch 104. When the pressing plate 207 is pressed, the two scissor blades 200 will rotate around the hinge 105 because the insertion holes 201 at the ends of the two scissor blades 200 are equipped with hinge pins 105. When the two scissor blades 200 rotate around the hinge pin 105, the cutting edge 202 of the two scissor blades 200 will cut the material. Since the arc-shaped notch 203 of the two scissor blades 200 is equipped with torsion springs 107, and the two ends of the torsion springs 107 are respectively engaged in the connection holes 204 of the two scissor blades 200, after cutting, when the operator releases the pressing plate 207, the two scissor blades 200 will rotate in the opposite direction around the hinge pin 105 under the action of the torsion springs 107 to return to their original position. The thread picking groove 205 on the outside of the scissor blades 200 can be used for tasks such as thread removal. The thread picking groove 205 can be used to pick up the thread.
