[0008] In a further embodiment, the bending angle between the flat plate portion and the positioning tube is 90°.

[0009] In a further embodiment, the bending angle between the flat portion and the raised portion is 90°.

[0010] In a further embodiment, the elastic fragments are symmetrically distributed on both sides of the positioning tube and the mounting body.

[0011] In a further embodiment, the width of the elastic member is smaller than the outer diameter of the positioning tube.

[0012] In a further embodiment, the extension portion is bent toward a side away from the positioning tube, and a bending angle between the extension portion and the connecting portion is 105°.

[0013] In a further embodiment, the rebound portion is bent toward a side close to the positioning tube, and a bending angle between the rebound portion and the extension portion is 150°.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The utility model provides that the entire shrapnel structure is made of a whole piece of material through punching, bending and other processing, and has higher stability. Among them, the cooperation between the flat plate part and the positioning cylinder makes the entire shrapnel easier to position and assemble, and is not easy to loosen during use. The provided raised part provides better support for the shrapnel body, so that the shrapnel body is not easy to deform under long-term extrusion and wear, has better recovery ability, effectively maintains its stable performance, and thus extends the service life of the shrapnel.

[0021] In the description of the present invention, it should be understood that terms such as "center," "longitudinal," "lateral," "upper," "lower," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are used solely to facilitate the description of the present invention and to simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0022] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-4 , a guide spring piece of an electric heating furnace control device includes an integrally formed mounting body, a positioning cylinder 21 and a spring piece body, wherein the mounting body includes a flat plate portion 11, a raised portion 12 and a through-hole 13. The flat plate portion 11 is a rectangular flat plate. After the rectangular flat plate is punched multiple times by the punch and the die to form the positioning cylinder 21, the top of the positioning cylinder 21 is punched through to form a through-hole 13, which is connected to the positioning cylinder 21. The bending part of the flat plate portion 11 and the positioning cylinder 21 is bent at 90 degrees, so that the through-hole 13 is more open, which is convenient for connecting the positioning piece passing through the positioning cylinder 21, thereby positioning and assembling, making it not easy to loosen. The raised portion 12 is formed by bending the two ends of the flat plate portion 11 to one side of the positioning cylinder 21. The bending angle between the flat plate portion 11 and the raised portion 12 is 90 degrees, and the raised portion 12 is punched out on both sides. A part of it is rectangular, leaving a spring body in the middle, which is symmetrically distributed on both sides of the positioning tube 21 and the mounting body. The width of the spring body is smaller than the outer diameter of the positioning tube 21, so that the width of the spring body is relatively narrow, which is convenient for elastic recovery, and the spring body includes a connecting portion 31, an extension portion 32 and a rebound portion 33, wherein the connecting portion 31 is connected to the protrusion 12, and the protrusion 12 supports the connecting portion 31 more firmly, making it less likely to deform, and the connecting portion 31 and the rebound portion 33 are respectively bent at both ends of the extension portion 32, and the extension portion 32 is bent to the side away from the positioning tube 21, and the bending angle between the extension portion 32 and the connecting portion 31 is 105°, and the rebound portion 33 is bent to the side close to the positioning tube 21, and the bending angle between the rebound portion 33 and the extension portion 32 is 150°.
