Detailed ways

As shown in FIG. 1 , a nail puller of the present invention includes a rectangular base plate 1, through which the base plate 1 is attached to the surface of furniture or other wooden products, thereby increasing the stress area during nail pulling, effectively reducing the damage to the surface of furniture or other wood products. A nail-pulling hole 2 is opened in the middle of the bottom plate 1 , so that the nail head can be exposed from the nail-pulling hole 2 .

A handle bar 3 is hinged on both sides of the nail pulling hole 2 on the bottom plate 1, the handle bar 3 and the bottom plate 1 are hinged through an axis IV12, and both ends of the axis IV12 are fixed in the axle bracket 13 arranged on the bottom plate 1. . The two handle bars 3 are provided with a hand-held sleeve 14 at one end away from the base plate 1 . The hand-held sleeve 14 is made of rubber material, which is convenient for users to hold and effectively avoids safety accidents caused by hand slippage during nail pulling. One end of the two handle bars 3 close to the bottom plate 1 is respectively connected with a connecting plate 4 by means of hinged connection to form a first lever structure. The two handle bars 3 are respectively provided with grooves II301 along the length direction for accommodating the corresponding connecting plates 4. The handle bars 3 and the corresponding connecting plates 4 are hingedly connected by the shaft III11, and both ends of the shaft III11 are fixed in the grooves. Inside II301.

A nail-pulling pliers are arranged between the two connecting plates 4, the nail-pulling pliers include two cross-hinged pliers rods 5, and the hinge point of the nail-pulling pliers is located on one end of the two pliers rods 5 close to the bottom plate 1, forming a second Leverage structure. In this embodiment, a baffle plate 6 perpendicular to the base plate 1 is provided on the side of the base plate 1 on the side of the nail pulling pliers, and a strip groove 7 perpendicular to the base plate 1 is opened on the baffle plate 6. The two pliers rods 5 They are hinged through the shaft I8, one end of the shaft I8 is fixed with one of the clamp rods 5, and the other end of the shaft I8 is arranged in the opening of the strip groove 7, and the stroke of the shaft I8 is limited by the strip groove 7, thereby limiting the pull out. The nail forceps can only reciprocate perpendicular to the bottom plate 1 to complete the nail extraction. Opposite jaws 501 are provided on the ends of the two pliers 5 near the bottom plate 1 , and the two jaws 501 correspond to the positions of the nail-extracting holes 2 on the bottom plate 1 , and then the nails exposed from the nail-extracting holes 2 unplug. The ends of the two pliers rods 5 away from the bottom plate 1 are respectively hinged with the free ends of the connecting plates 4 on the two handle rods 3, and the ends of the two pliers rods 5 away from the bottom plate 1 are respectively provided with corresponding connecting plates 4 along the length direction. In the groove I502, the clamp rod 5 and the corresponding connecting plate 4 are hinged through the shaft II9, both ends of the shaft II9 are fixed at the end of the groove I502 away from the bottom plate 1, and a rubber is provided between the two shafts II9 The rib makes the utility model keep the retracted state through the hinge of each shaft when not in use, thus saving space.

The rotation directions of the handle bar 3, the connecting plate 4 and the pincer bar 5 in the present invention are all arranged on the same plane. When it is necessary to pull out the nails, first place the bottom plate 1 close to the surface of the furniture or other wood products and place the nails in the middle of the nail-pulling holes 2 . Then open the two handle bars 3 to both sides, push the two pliers bars 5 to move toward the bottom plate 1, and under the guidance of the grooves 7 on the baffle 6, the two jaws 501 of the nail-pulling pliers move until the nails are pulled out. Hole 2 and open. Then the two handle bars 3 are retracted, and the two jaws 501 of the nail pulling pliers clamp the nail head under the pulling force of the rubber band, and finally the two handle bars 3 are continuously retracted, and the nail pulling pliers are on the baffle plate. The grooves 7 on the 6 are guided away from the base plate 1, so that the nails can be easily pulled up vertically. In the process of nail pulling, it is affected by two levers, which has obvious labor-saving effect, and there will be no relative displacement between the bottom plate 1 and the surface of furniture or other wood products with nails, avoiding the need for furniture or other Damage to the surface of wood products.
