Abstract

The utility model relates to an iron nail holding structure which provides a stable holding tool when iron nails are nailed. The holding structure is characterized in that an inner triangular wedge and an outer triangular wedge are used for holding round iron nails, and three produced holding points are not collinear, but can form a circle. The holding forces of the three points to the iron nails have optimum balance effect under external force, and thus the iron nail holding structure exerts the stablest holding function when iron nails are nailed.

Description

Iron nail holding structure

A kind of iron nail clamp structure mainly is that a kind of more firm iron nail clamping device is provided when construction, to alleviate the burden in the construction.

Existing iron nail clamping device mostly directly comes the clamping iron nail with general pliers, clip even hand, make and be kept upright on the position that will hammer into, but when hammering into, because employed impact is difficult to hammer into direction identical utterly, so the component different with hammering into direction promptly might cause the crooked even crooked of iron nail, set upright or change and need choose again, so the equilibrant force size that the iron nail clamping device can provide just seems extremely important.

Existing iron nail clamping device, as shown in Figure 1, 2, its bite concentrates on two extreme A, B of iron nail circular cross section mostly, no matter be that 2 or multiple spot are all the same.Because the holding power of keeping balance has only two approximate relative directions, so the component C of impact is if any the strength C1 greatly of vertical this direction, and then this iron nail might not have bracing force because of this direction and produces crooked or crooked result.

The purpose of this utility model is, a kind of more firm iron nail clamping device is provided during construction, and this instrument can overcome the defective of existing iron nail clamping device.

Solving technical measures of the present utility model is, mainly be utilize three not conllinear and the bite that can constitute a circle impact force from all directions is produced the optimum balance reaction force, and these 3 be the best with similar equilateral triangle.

Now, in conjunction with the accompanying drawings an embodiment of the present utility model is illustrated in detail.

Wherein:

Fig. 1 represents the clamping situation (vertical view) of existing iron nail clamping device,

Fig. 2 represents the clamping situation (side view, only part illustrates) of existing iron nail clamping device,

Fig. 3 represents the stereogram of the utility model embodiment,

Fig. 4 represents the fragmentary detail view of the utility model embodiment.

The utility model embodiment is to use Tripurpose pliers, its structure sees also shown in Figure 3, mainly by two iron or steel sheet metal 1,2 with pivot 3 combinations, one end is the handle 11,21 that is suitable for grasping, the other end then has three kinds of shapes to be fit to three kinds of functions, at first be the

pincers tooth

12,22 of the general article of folder, come the

nail holder

13,23 used for clip nail again, the back then is the

cable cutter

14,24 of bladed.Utilize pivot 3 to be fulcrum, the application of force makes two handles 11,21 adjacent to each other, by lever principle as can be known.The other end will produce the function that the strength bigger than the former application of force is pressed from both sides thing, clip nail or tangent line.

The nail holder member one of the utility model embodiment is outer triangle wedge shape 13, another is interior triangle wedge shape 23, and the two is all similar equilateral triangle and can engages fully, when nail holder clamping iron nail 4, by three bites, 5,6, the 7 chucking power D that produced, E, the F that will have approximate equilateral triangle shown in Figure 4, after the component G1 effect that is impacted, three chucking powers will appropriateness produce reaction force, to prevent the crooked or crooked of iron nail.

In sum, the utility model can increase Practical Benefit in the use really, and its triangle wedge shape clamp structure in general instrument or other public occasions, do not see have identical, so the application real be novelty and practical creation.

Claims

A kind of iron nail clamp structure, by two sheet metals with pivot in conjunction with forming, one end is the handle that is suitable for grasping, the other end is the retained part that comprises nail holder, it is characterized in that nail holder member one is outer triangle wedge shape, another is interior triangle wedge shape, and the two is all similar equilateral triangle and can engages fully, during the clamping iron nail it is produced three bites of similar equilateral triangle.
