Abstract
The invention discloses a spring piece with a buffer structure. The spring piece comprises a welding plane, a U-shaped bending part, an adsorption plane and a contact part, wherein the U-shaped bending part is formed in a way that one end of the welding plane is bent upward, the adsorption plane is formed in a way of extending from the U-shaped bending part, the contact part is formed in a way of extending from the adsorption plane upward, and a buffer piece which is used for preventing the contact part from being excessively pressed is arranged on one side of the welding plane in an extension way, which is close to the contact part. Because the buffer piece is arranged on one side of the welding plane in the extension way, which is close to the contact part, when the contact part is pressed to a specified position, the contact part comes into contact with the buffer piece to buffer, so as to prevent the contact part from being excessively pressed and avoid deformation damage of the spring piece.
Description
Technical field
The present invention relates to a kind of shell fragment, relate in particular to a kind of shell fragment of tool buffer structure.
