Description

Technical Field

[0001] This utility model relates to the field of sewing tools, and more particularly to a thimble. Background Technology

[0002] A thimble is a traditional sewing tool, primarily used to assist in hand sewing, protecting the fingers and increasing strength. It is typically a hoop-shaped tool made of iron or copper. Wearing a thimble involves threading the finger through the thimble hole, which can easily get stuck at the finger joint. Traditional thimbles are very stiff and uncomfortable to wear; their size is fixed, but everyone's finger size is different, and finger size varies at different times—thicker fingers are thicker when overweight, thinner fingers are slender when thinner. The original thimble either cannot be inserted or is too large and loose, easily slipping off. Utility Model Content

[0003] To overcome the inconvenience of wearing a thimble and the problem that its diameter is not adjustable, this utility model provides an adjustable thimble.

[0004] This utility model embodiment provides an adjustable ejector pin, the adjustable ejector pin comprising:

[0005] The flexible body has a first side and a second side.

[0006] An adjustment mechanism is provided on the bendable body, and the size of the bendable body can be adjusted by connecting or disconnecting the adjustment mechanism.

[0007] Preferably, the bendable body is made of a flexible material, including leather, silicone, or fabric.

[0008] Preferably, the adjustment mechanism is a hook and loop fastener assembly, comprising: a first component fixed to a first side of the bendable body, the surface of the first component having a plurality of hook-shaped protrusions; and a second component fixed to a second side of the bendable body, the surface of the second component having a fiber ring structure; wherein the hook-shaped protrusions and the fiber ring structure are detachably engaged to adjust the diameter of the bendable body.

[0009] Preferably, the adjustment mechanism is a magnetic attraction assembly, comprising: a magnetic conductor fixed to a first side of the bendable body; and a magnetic component fixed to a second side of the bendable body; wherein the magnetic component and the magnetic conductor are detachably connected by magnetic attraction to adjust the diameter of the bendable body.

[0010] Preferably, the flexible material is a fabric, and the fabric is selected from carbon fiber fabric or metal fiber fabric.

[0011] The adjustable pin provided in this embodiment of the utility model has a simple structure, is easy to manufacture and has low cost. It is easy to wear by wrapping, and its diameter can be adjusted according to the size of the fingers. Attached Figure Description
