Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 3, a cutter for preventing force from being broken comprises a cutter handle 1, an outer frame 3 and a detection piece 7; frame 3 is located the outside of handle of a knife 1, frame 3 and 1 fixed connection of handle of a knife for ensure synchronous motion between the two, frame 3 includes ring 4, connecting piece 5 and limiting plate 6, limiting plate 6 passes through connecting piece 5 and is connected with ring 4 for the position of restriction detection piece 7, connecting piece 5 is located the outside of cutting edge 2 on the handle of a knife 1, detection piece 7 is located the outside of connecting piece 5, the inner wall and the 5 contact of connecting piece of detection piece 7 for detect the position change of connecting piece 5, detection piece 7 and the contact of limiting plate 6 for the position of restriction detection piece 7, detection piece 7 includes outer loop 8, inductor 9 and spacing 10, outer loop 8 and connecting piece 5 and the contact of limiting plate 6, inductor and external control system electric connection.

Ring 4 and 1 size cooperatees of handle of a knife, connecting piece 5 evenly distributed on ring 4 for ensure the accurate nature that detects 7, limiting plate 6 separates with detecting 7, is used for placing and detects 7.

The ring 4 is concentric with handle of a knife 1, connecting piece 5 is symmetrical about cutting edge 2 for ensure the accurate nature that detects 7 detection, connecting piece 5 is made by the spring steel, is used for ensuring that connecting piece 5 can take place slight deformation and produce pressure to inductor 9 under the drive of cutting edge 2, thereby judges the change of 2 shapes of cutting edge, connecting piece 5 separates with cutting edge 2.

Inductor 9 link up outer loop 8, inductor 9 specifically is pressure sensor for through the change of pressure detection connecting piece 5 position, and then detect the change of 2 positions of cutting edge, spacing 10 specifically is located outer loop 8, outer loop 8 and connecting piece 5 and limiting plate 6 separation.
