Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Example 1

A three-leg fixing nail comprises a V-shaped nail cap 1 and three nails 2 which are integrally formed with the V-shaped nail cap 1 and perpendicular to the V-shaped nail cap 1, wherein the three nails 2 are respectively fixed right below an intersection point and two edge points of two sides of the V-shaped nail cap 1.

In this embodiment, the three-leg fastening nail is an integrally formed structure, and three sides of the three-leg fastening nail are respectively bent and folded after the steel plate is punched into a Y shape by using a die, as shown in fig. 2, so as to form an integral structure including a V-shaped nail cap 1 and a V-shaped nail cap 1. The included angle of two sides of the V-shaped nail cap 1 is 60 degrees, and three nail needles 2 are respectively three vertexes of a regular triangle.

The three-leg fixing nail changes the binding mode that only one line of contact is arranged between the traditional fixing nail and the bound object, and the contact area between the V-shaped nail cap 1 and the bound object is increased after binding, so that the binding is firmer. Meanwhile, the V-shaped structure is convenient to arrange and suitable for continuous conveying.

The nail row based on the three-foot fixing nail is characterized in that more than two three-foot fixing nails are connected in a row through gluing.

Example 2

A binding apparatus using the three-legged staple or staple row of embodiment 1, comprising a base 3 and a staple feeding assembly and a staple pressing assembly rotatably connected to the base 3, wherein: the nail feeding assembly comprises a nail bin 6 for containing rows of three-foot fixing nails and a pushing plate 7 which is driven by a pushing spring 8 to press the three-foot fixing nails, and the front end of the nail bin 6 is provided with a through hole 11 for the three-foot fixing nails to pass through; the nail pressing assembly comprises a pressing handle 9 and a V-shaped pressing sheet 10 fixedly connected with the pressing handle 9, and when the pressing handle 9 and the V-shaped pressing sheet 10 are driven downwards by external force, the pressing handle and the V-shaped pressing sheet are positioned right above the three-pin fixing nail at the foremost end of the nail bin 6; the base 3 is provided with a deformation groove 5 for promoting the deformation of the fixing nail, and the deformation groove 5 comprises three grooves corresponding to the positions of the three nail needles 2 of the three-foot fixing nail.

When the nail magazine is used, the three-leg fixing nails (nail rows) which are tightly arranged are placed into the nail magazine 6, and the pushing plate 7 pushes the three-leg fixing nails to the front end of the nail magazine 6 under the pushing of the pushing spring 8. The pressing handle 9 is pressed to push the V-shaped pressing sheet 10 downwards, and the tripod fixing nail at the foremost end of the nail bin 6 is extruded out through the through hole 11. After the three-pin fixing nail is extruded through the through hole 11 and penetrates through an object to be bound, the bottom ends of the three nail needles 2 contact with the deformation groove 5 to be deformed and bent, and therefore binding is completed.

Preferably, the base 3 is fixedly connected with a connecting piece 4, the end of the nail supply assembly is inserted into the connecting piece 4 and is rotatably connected with the connecting piece 4, and the pressing handle 9 is sleeved outside the connecting piece 4 and is rotatably connected with the connecting piece 4. The connection mode is rotated to enable the nail feeding assembly and the nail pressing assembly to rotate, so that the three-leg fixing nails can be conveniently placed into the nail bin 6, and meanwhile, the three-leg fixing nails can be conveniently adjusted according to the thickness of an article to be bound.

Preferably, one end of the pushing spring 8 is connected with the pushing plate 7, and the other end is connected with the tail end of the nail bin 6. The arrangement of the pushing spring 8 ensures that the three-pin fixing nail in the nail bin 6 is always positioned at the front end, and the binding work can be carried out at any time.

Preferably, a protrusion is arranged on a sharp corner at the front end of the V-shaped pressing sheet 10 and is matched and connected with a fixing groove on the inner wall at the front end of the nail bin 6 to form fixing. After the three-leg fixing nail is arranged in the nail bin 6, the nail supplying component and the nail pressing component can be combined together for convenient use in order to facilitate binding. A bulge is arranged on the sharp corner at the front end of the V-shaped pressing sheet 10, a fixing groove is arranged on the inner wall of the front end of the nail bin 6, the bulge and the fixing groove are mutually matched and connected, and the bulge and the fixing groove can be separated under the condition of applying certain force.

Preferably, a first groove of the three deformation grooves 5 is arranged parallel to the base 3, and the other two grooves are symmetrical with respect to the first groove. As shown in fig. 5, the three grooves point to the center of the regular triangle respectively, so that the top ends of the three pins 2 contact with the deformation grooves 5 to deform and bend, and the three pins 2 formed by binding are all close to the center, thereby preventing the bound object or the hand from being scratched.

Preferably, sliding grooves 12 are formed in both sides of the magazine 6, pushing pieces 13 are fixed to both sides of the pushing plate 7, and the pushing pieces 13 pass through the sliding grooves 12 and slide in the sliding grooves 12. When the three-leg fixing nail is installed, the pushing sheet 13 is pushed backwards to reserve a position for the three-leg fixing nail. Meanwhile, due to the existence of the sliding groove 12 and the push piece 13, the number of the internal tripod fixing nails can be observed outside the nail bin 6 according to the position of the push piece or through the sliding groove 12, so that the tripod fixing nails can be supplemented in time.

Preferably, the pressing handle 9 is of an open-bottom structure, and the top end of the V-shaped pressing sheet 10 is fixedly connected in the cavity of the pressing handle 9. The design reduces the volume of the pressing nail component, so that the whole binding device is simpler and more portable and is convenient to carry and use.

Preferably, as shown in fig. 7, a storage cavity 16 capable of accommodating the spare tripod fixing nails and a cavity cover plate 18 for closing the storage cavity 16 are arranged at the bottom of the base 3, the area of the cavity cover plate 18 is larger than the sectional area of the storage cavity 16, one end of the cavity cover plate 18 is hinged to the base 3, and the other end of the cavity cover plate 18 is connected with the base 3 through a magnetic sheet. The current binding device products are generally not provided with a spare nail storage cavity, and most of the spare nail storage cavities are matched with a single box of fixing nails. It often happens that the binding device is found but the staple is not found during daily work and learning. The storage cavity 16 is arranged on the base 3, so that the problem is solved, and the use is more convenient.

Example 3
