Description

Nail puller for pulling high nail

Technical Field

The utility model relates to a nail nipper especially relates to a nail nipper for drawing high department nail.

Background

Nails are very common connectors. The connection by the nail is more difficult to disassemble than the connection by the bolt, and the components are easy to damage in the disassembling process, but the connection is still detachable. The removal of two connected components can be achieved by removing the nail without removing the components with the aid of tools such as claw and claw hammers.

The force to pull the bolt out is converted to a force to resist the bolt being pulled out due to the thread friction angle, so the bolt does not need to be very tightly coupled with the member. However, unlike the nail, the nail can be regarded as a bolt with a friction angle of 0 and a lead angle of 90 degrees, so that the force for pulling out the bolt is not converted into the force for preventing the bolt from being pulled out, and therefore the nail needs to be tightly combined with the component to ensure that the nail cannot fall off in the using process.

However, the nails need to be very tightly bonded to the structure, meaning that a great deal of resistance needs to be overcome when pulling the nail. This problem is overcome when pulling nails from a ground/stable platform, which is dangerous and difficult in situations where force is inconvenient, such as work high above ground. Use the nail on the roof board line box of pulling out when fitment as an example, because exert oneself inconveniently (fall easily with too big), sometimes need pound the broken nail of conveniently pulling out of line box even, caused extra loss.

SUMMERY OF THE UTILITY MODEL

The utility model provides a nail nipper for drawing high department nail.

The technical problem to be solved is that: in the occasions where force is not convenient to apply, such as high-altitude operation, nail pulling is difficult and dangerous.

In order to solve the technical problem, the utility model adopts the following technical scheme:

the claw is arranged at one end of the claw arm, and the claw arm of the nail puller comprises a top wall arm supported at a position to be nailed and a handle arm used for being held on the ground;

the top wall arm is in a right-angle U shape, the tail end of the top wall arm is propped at the position to be nailed, and the bottom section of the top wall arm is crossed with the handle arm and is hinged with the handle arm;

and a return spring used for clamping the nail nippers under the unused state is also arranged between the top wall arm and the handle arm.

Further, the handle arm is a straight rod; when the nail nipper is in a clamping state, the handle arm is perpendicular to the bottom section of the top wall arm.

Further, the claw pincers further comprise an additional supporting rod used for assisting the top wall arm to be fixed, one end of the additional supporting rod is propped at the position to be nailed, the other end of the additional supporting rod is fixedly connected with the end portion, close to the claw, of the top wall arm, and the end portion, at the position to be nailed, of the top wall arm and the top portion of the claw on the top wall arm are propped by the additional supporting rod in a collinear mode.

Further, a sleeve for inserting the extension handle is anchored at the tail end of the handle arm, and the sleeve and the handle arm are coaxially arranged.

Further, the reset spring is a tension spring, one end of the tension spring is fixedly connected with the front part of the shaft of the top wall arm, and the other end of the tension spring is fixedly connected with the rear part of the shaft of the handle arm.

Furthermore, the tension spring is fixedly connected with the two forceps arms respectively through pull rings anchored on the forceps arms.

Furthermore, the material of the claw is manganese steel.

The utility model relates to a nail nipper for drawing high department nail compares with prior art, has following beneficial effect:

in the utility model, the shape of the nail nipper is changed, so that the nail nipper can be supported at the position to be nailed; the nail puller can be operated on a base surface by connecting the extension handle to one clamp arm; through the arrangement of the return spring, the nail puller can clamp a nail at a high position to pull out the nail under the condition that only one tong arm is operated, so that dangerous operation of pulling out the nail in high-altitude operation is avoided.

Detailed Description

As shown in fig. 1-2, a pair of nail nippers used for pulling out a nail at a high position comprises two nipper arms and a nipper claw 3 arranged at one end of the nipper arms, wherein the nipper arms of the nail nipper comprise a top wall arm 1 supported at a position to be nailed and a handle arm 2 used for being held on the ground; the top wall arm 1 is in a right-angle U shape, the tail end is supported at the position to be nailed, and the bottom section 11 of the top wall arm 1 is crossed with the handle arm 2 and is hinged with the handle arm.

A return spring 4 for clamping the nail nipper in an unused state is also arranged between the top wall arm 1 and the handle arm 2. The return spring 4 enables the claw to grip a high nail 7 for extraction by operating only one of the jawarms.

The handle arm 2 is a straight rod; when the nail nipper is in the clamping state, the handle arm 2 is arranged perpendicular to the bottom section 11 of the top wall arm 1. The handle arm 2 not only plays a role of holding by hand, but also serves as a lever, so that a straight rod is made to facilitate force application.

The rear end of the handle arm 2 is anchored with a sleeve 61 for inserting an extension handle 62, the sleeve 61 being arranged coaxially with the handle arm 2. Of course, the handle arm 2 can be extended directly without using the extension handle 62, but that is inconvenient for storage.

Nail nipper is arranged in pulling out nail 7 in the line box of eminence in this embodiment, because 7 borders of nail have a line box's frame, the long handle claw hammer that uses before can't be used for pulling out nail 7 here, therefore we have designed the utility model discloses. The claw 3 of the claw in this embodiment can be extended into the frame to pull out the nail 7, but the long-handled claw hammer cannot.

The claw pincers further comprise an additional supporting rod 5 used for assisting the top wall arm 1 to be fixed, one end of the additional supporting rod 5 is propped at the position to be nailed, the other end of the additional supporting rod is fixedly connected with the end portion of the top wall arm 1 close to the claw 3, and the end portion of the additional supporting rod 5 is propped at the position to be nailed, the top portion of the claw 3 on the top wall arm 1 and the tail end of the top wall arm 1 are arranged in a collinear mode.

In this embodiment, the return spring 4 is a tension spring, one end of which is fixedly connected to the front portion of the shaft of the top wall arm 1, and the other end of which is fixedly connected to the rear portion of the shaft of the handle arm 2. The tension spring is fixedly connected with the two clamp arms through pull rings anchored on the clamp arms respectively. Of course, a spiral spring of the type of a spring hinge may be used as the return spring 4, but the spiral spring is inconvenient to install and cannot be replaced by a general worker without force if it is dropped or damaged.

The material of the claw 3 is manganese steel. In the jaw 3 of this embodiment, the biting surface is edged, and the center of the biting surface has a notch for holding the nail 7, so that it is necessary to use wear-resistant manganese steel.

As shown in fig. 2, the utility model relates to a nail nipper for drawing high nail, its installation includes following step:

the method comprises the following steps: an extension handle is inserted into the sleeve 61;

step two: lifting the nail nippers to enable the tail ends of the top wall arms 1 and the upper ends of the additional support rods 5 to be propped against the positions to be nailed;

step three: the claw 3 is opened to clamp the nail 7, and the handle arm 2 is pulled towards the tail end of the top wall arm 1 to pull out the nail 7.

The above-mentioned embodiments are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art without departing from the design spirit of the present invention should fall into the protection scope defined by the claims of the present invention.
