Detailed Description

As shown in figure 1, the utility model discloses a nail puller, including the bottom plate 1 of a rectangle, through the laminating of the surface of this bottom plate 1 with furniture or other woodwork, the lifting surface area when having increased the nail of pulling out has effectively reduced furniture or the surperficial damage of other woodwork. The middle part of the bottom plate 1 is provided with a nail pulling hole 2, so that the head of a nail can be exposed out of the nail pulling hole 2.

Two sides of the nail pulling hole 2 on the bottom plate 1 are respectively hinged with a handle rod 3, the handle rod 3 is hinged with the bottom plate 1 through a shaft IV12, and two ends of the shaft IV12 are fixed in a shaft bracket 13 arranged on the bottom plate 1. Two handle bars 3 all are equipped with handheld cover 14 in the one end of keeping away from bottom plate 1, and handheld cover 14 adopts the rubber materials preparation, and the person of facilitating the use grips, effectively avoids pulling out nail in-process hand cunning to cause the incident. One ends of the two handle rods 3 close to the bottom plate 1 are respectively connected with a connecting plate 4 in a hinged mode to form a first lever structure. Two handle rods 3 are respectively provided with a groove II301 for accommodating the corresponding connecting plate 4 along the length direction, the handle rods 3 and the corresponding connecting plates 4 are hinged through a shaft III11, and two ends of the shaft III11 are fixed in the grooves II 301.

The nail pulling pliers are arranged between the two connecting plates 4 and comprise two pliers rods 5 hinged in a cross mode, and the hinge joint of the nail pulling pliers is located at one end, close to the bottom plate 1, of the two pliers rods 5 to form a second lever structure. In the embodiment, a baffle 6 perpendicular to the bottom plate 1 is arranged on one side of the nail pulling forceps on the bottom plate 1, a strip-shaped groove 7 perpendicular to the bottom plate 1 is formed in the baffle 6, the two forceps rods 5 are hinged through a shaft I8, one end of a shaft I8 is fixed with one of the forceps rods 5, the other end of the shaft I8 is arranged in the strip-shaped groove 7, and the stroke of the shaft I8 is limited through the strip-shaped groove 7, so that the nail pulling forceps are limited to move back and forth only perpendicular to the bottom plate 1, and nail pulling is completed. The two clamp rods 5 are provided with opposite jaws 501 at the ends close to the bottom plate 1, and the two jaws 501 correspond to the nail pulling holes 2 on the bottom plate 1 in position, so that the nails exposed from the nail pulling holes 2 can be pulled out. The one end that bottom plate 1 was kept away from to two tong bar 5 is articulated mutually with the free end of two handle bar 3 upper junction plates 4 respectively, and two tong bar 5 are equipped with the recess I502 that holds corresponding connecting plate 4 along length direction respectively in the one end of keeping away from bottom plate 1, and all articulated mutually through axle II9 between tong bar 5 and the corresponding connecting plate 4, and the both ends of axle II9 are fixed bottom plate 1's tip is kept away from to recess I502, and is equipped with the rubber band between two axle II9, makes the utility model discloses when not, through the articulated shrink state that keeps of each axle, save space.

The utility model provides a handle pole 3, connecting plate 4 and tong pole 5's rotation direction all sets up on same plane. When the nail needs to be removed, the base plate 1 is firstly pressed close to the surface of furniture or other wood products, and the nail is positioned in the middle of the nail removing hole 2. Then the two handle rods 3 are opened towards two sides, the two clamp rods 5 are pushed to move towards the bottom plate 1, and the two jaws 501 of the nail nipper move to the nail pulling hole 2 and are opened under the guide of the strip groove 7 on the baffle 6. Then the two handle rods 3 are adducted, the two jaws 501 of the nail pulling pliers clamp the head of the nail under the auxiliary action of the pulling force of the rubber band, and finally the nail pulling pliers are kept away from the bottom plate 1 under the guide of the strip-shaped groove 7 on the baffle 6 through the continuous adduction of the two handle rods 3, so that the nail can be easily and vertically pulled up. In the process of nail pulling, the influence of two lever actions is received, the obvious labor-saving effect is achieved, relative displacement cannot be generated between the bottom plate 1 and the surface of furniture with nails or other wooden products, and the damage to the surface of the furniture or other wooden products is avoided.
