A warped piece comprises a rotary part, a left warped part, a left end part, a convex cylinder, a right warped part, a right bent part and a tine part; a rotary circular hole is formed in the rotary part, and the posture, that the axis of the rotary circular hole of the rotary part is parallel to the ground, of the warped part serves as the posture used for describing the structure of the warped piece through characters; the lower end of the left warped part is connected with the lowest point of the cylindrical face of the rotary part, and the upper end of the warped part is connected with the left end part (S62); the bottom face of the left end part (S62) is connected with the upper end face of the convex cylinder (S63), the lower end of the right warped part (S64) is connected with the lowest point of the cylindrical face of the rotary part (S61), and the upper end of the right warped part (S64) is connected with the left side of the right bent part (S65); and the upper end of the tine part (S66) is connected with the right end of the right bent part (S65), and the lowest point of the lower end of the tine part (S66) is lower than the lowest point of the cylindrical face of the rotary part (S61). The warped piece has the characteristics that the warped piece can be used for manufacturing a scabbard of a fruit knife, carrying and using are convenient, using is safe, and the warped piece is not prone to incidental injury.

The invention provides a punching device which comprises a first forceps arm, a second forceps arm, a punching needle and a first through hole. The connection structure is used for movably connecting the first forceps arm and the second forceps arm which are arranged in a crossed mode, dividing the first forceps arm into a first operation section and a first working section, and dividing the second forceps arm into a second operation section opposite to the first operation section, and a second working section opposite to the first working section. The punching needle is arranged on the first working section and comprises a threading hole or threading groove used for threading. The first through hole is formed in the second working section and opposite to the punching needle, and can allow the punching needle to penetrate through. According to the punching device, the threading hole or threading groove used for threading is formed in the punching needle; before punching, a thread or steel wire can penetrate into the threading hole or threading groove; after punching is finished, the punching needle passes through together with the thread; threading is completed during punching; compared with a traditional punching device, threading holes do not need to be found after punching any more, threading is easy, and the work efficiency is high.

The invention discloses a slide block. The slide block is characterized in that the cross section of the slide block (S5) is C-shaped; restrained slide teeth (S52) are arranged on an open part of the slide block (S5); and convex teeth (S51) are arranged on the middle part of the slide block (S5). A fruit knife is characterized in that a switch is locked through the slide block. The slide block can be used for manufacturing a sheath of the fruit knife, has the characteristics of being convenient to carry and convenient to use, is safe to use, and is not liable to cause accidental injury.
