Embodiment

See also Fig. 1, the preferred embodiments of fastening piece of the present invention comprises that one first holding limb 10 that pivot to connect and one second holding limb 20, a fixed plate 30, an elastic component 40 and are connected the bearing pin 50 of said first and second holding limb 10,20.In this mode of execution, said elastic component 40 is a spring.

The clamping part 14 that said first holding limb 10 comprises a cylindrical fixing part 12, extended to an end by the top of said fixing part 12 and by the top of said fixing part 12 a operation unit 16 to another opposite end diagonally extending.Said fixing part 12 is provided with a through hole 122.The bottom of said clamping part 14 is provided with the bayonet socket 142 of a semicircle, and the inwall of said bayonet socket 142 is provided with internal thread.Said clamping part 14 is provided with the T-shaped chute of a cross section 144 away from the end face of said fixing part 12.The bottom of said operation unit 16 is convexly equipped with a projection 162.

Said second holding limb 20 comprises a buckling part 22, operating arms 24 relative with said buckling part 22 and two lugs 26 between said buckling part 22 and said operating arm 24.Said lug 26 is cylindric, and is convexly set in the end face of said second holding limb 20 in opposite directions.Each lug 26 is provided with a pivoting hole 262.The end face depression one of said buckling part 22 has the semicircular opening 222 of internal thread.Said buckling part 22 is provided with a T-shaped fluting 224 away from the end face of said lug 26.The end face of said operating arm 24 is provided with a fixing column 242.

Said fixed plate 30 is processed by magnetic material, like magnet.Said fixed plate 30 comprises that the end that a fixed block 32 reaches by said fixed block 32 is convexly equipped with the operating block 34 that forms.In this mode of execution, said first and second holding limb 20 is processed by magnetic material or metallic iron, so that absorption is fixing each other with said fixed plate 30.

Please with reference to Fig. 2, during assembling, the fixed block 32 of said fixed plate 30 is sticked in the fluting 224 of said second holding limb 20, and the operating block 34 of said fixed plate 30 exposes to the end face of said second holding limb 20 through said fluting 224.The fixing part 12 of said first holding limb 10 inserts between two lugs 26 of said second holding limb 20, and the through hole 122 of said fixing part 12 aligns with the pivoting hole 262 of said lug 26.Said bearing pin 50 passes said through hole 122 and said pivoting hole 262, connects with what said first and

second holding limb

10,20 was pivoted.At this moment, the chute 144 of said first holding limb 10 aligns with the fluting 224 of said second holding limb 20, and said fixed plate 30 can slide between said chute 144 and said fluting 224.The bayonet socket 142 of said first holding limb 10 aligns with the opening 222 of said second holding limb 20, forms the clamping hole 60 of a circle, with clamping one threaded piece (like screw, screw rod etc.).At this moment, the internal thread of this clamping hole 60 and this threaded piece screw togather, and get loose to prevent this threaded piece.Two opposite ends of said elastic component 40 are individually fixed in the projection 162 of said first holding limb 10 and the fixing column 242 of said second holding limb 20.

Please combine with reference to Fig. 3, during use, push operation unit 16, the operating arm 24 of said first and

second holding limb

10,20 in opposite directions, the clamping part 14 of said first and

second holding limb

10,20, buckling part 22 around said bearing pin 50 rotates each other away from.At this moment, said elastic component 40 is extruded distortion.The bayonet socket 142 of said first holding limb 10 is placed on threaded piece (like screw, screw rod etc.), unclamps said operation unit 16 and the extruding of said operating arm 24 ground, elastic component 40 elastic-restoring forces force said clamping part 14 and said buckling part 22 move toward one another.At this moment, but the clamping hole 60 clamping threaded pieces (like screw, screw rod etc.) that the opening of said bayonet socket 142 and said second holding limb 20 222 forms.The operating block 34 of said fixed plate 30 slides; Opposite end with the fixed block 32 that uses said fixed plate 30 is contained in said chute 144 and said fluting 224 respectively; Fixed plate 30 said first and second holding limb 20 of absorption and said threaded pieces (like screw, screw rod etc.) are so that said fastening piece and said threaded piece (like screw, screw rod etc.) closely cooperate.

During dismounting, the operating block 34 of the said fixed plate 30 that slides skids off chute 144 with the fixed block 32 that uses said fixed plate 30.Push operation unit 16, the operating arm 24 of said first and

second holding limb

10,20 in opposite directions, the clamping part 14 of said first and

second holding limb

10,20, buckling part 22 around said bearing pin 50 rotates each other away from.At this moment, just can threaded piece (like screw, screw rod etc.) be taken out from fastening piece, simple to operation, convenient.

In other embodiments, said fastening piece also can be provided with the buckle and the hole clipping of mutual engaging respectively at said first and

second holding limb

10,20.
