The nail is characterized in that the middle of the nail body is provided with a cavity; the cavity is internally provided with an ejector pin of which the length is less than that of the cavity and the head part is wedge shaped; two sides of the head part of the ejector pin are provided with transverse through holes; each through hole is internally provided with a moving block; one end of the moving block is in contact with the wedged surface of the head part of the ejector pin, and the other end of the moving block is in level with the surface of the nain body. After the anti-loose nail disclosed by the utility model is driven in, the ejector pin is pushed forward, thus the moving block is protruded transversely, and the nail is prevented from being loose and being pulled away.
Description
Technical field
The utility model relates to a kind of five metals device, particularly relates to a kind of locking nail.
Background technique
Common nails hammers into the back because vibrations or stressed meeting are become flexible gradually, deviate from.
Summary of the invention
The utility model purpose is that the defective to existing technology provides and prevents to become flexible the nail deviate from after a kind of the hammering into.
The utility model adopts following technological scheme for realizing above-mentioned purpose:
A kind of locking nail comprises the nail body, it is characterized in that: be provided with a cavity in the middle of the said nail body; Be provided with a length in the said cavity less than cavity length; Head is the thimble of wedge shape, and said thimble head both sides are provided with cross through hole, are provided with movable block in the through hole; Said movable block one end contacts with said thimble head wedge surface, and the other end is concordant with said nail body surface.
After the utility model hammers into, thimble is pushed forward into, makes movable block outstanding, thereby prevent that nail from becoming flexible to laterally.
Description of drawings
Fig. 1 is the utility model schematic representation;
1, nail body; 2, thimble; 3, movable block.
Embodiment
A kind of locking nail as shown in Figure 1; Comprise nail body 1, be provided with a cavity in the middle of the said nail body 1, being provided with a length in the said cavity is the thimble 2 of wedge shape less than the cavity length head; Said thimble head both sides are provided with cross through hole; Be provided with movable block 3 in the through hole, said movable block 3 one ends contact with said thimble 2 head wedge surfaces, and the other end is concordant with said nail body 1 surface.
Thimble is pushed forward into after during use nail being hammered into, the wedge surface of thimble head is released said movable block to both sides again, thereby outstanding nail body surface makes the firm embedding of nail body follow closely in the object, prevents that it is because of shaking or stressedly becoming flexible.
