Description

Technical Field

[0001] The utility model specifically relates to the field of nail pullers, in particular to a nail puller which is easy to use. Background Art

[0002] A nail puller, also called a nail remover, is a tool used to remove fasteners such as nails and screws. It is generally composed of a handle and a pair of jaws. The color of the jaws is generally red or blue, and the handle is generally black or yellow. During use, the jaws of the nail puller need to be placed on the nail or screw to be removed, and the handle is pulled upward with force. The jaws will clamp the fastener and remove it.

[0003] The existing nail puller has a simple structure. When pulling out a nail, the nail needs to be fixed in the clamping jaws of the nail puller and then pulled out with force. Since the existing nail pullers mostly use curved rotation to pull out the nail, the nail is easily bent and the object fixed by the nail is damaged during the nail pulling process. After the nail is pulled out, the nail hole becomes larger and the nail pulling effect is poor.

[0004] For this reason, we propose a nail puller that is easy to use to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problems in the prior art that nails are easily bent and nail holes become larger when nails are pulled out by nail pullers, and to provide a nail puller which is easy to use.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A nail puller that is easy to use comprises a main body, two clamping members are arranged at the bottom of the main body, two fixing plates are rotatably connected to the outside of the two clamping members, the upper ends of the four fixing plates are fixedly connected to the main body, a driving mechanism for driving the two clamping members is arranged on the main body, a fixing ring is fixedly connected to the outside of the main body, two supporting columns are passed through the upper and lower ends of the fixing ring, the lower ends of the two supporting columns are fixedly connected to the same supporting ring, the upper ends of the supporting columns are fixedly connected to the same pressing ring, and pressing handles are fixedly connected to the left and right ends of the fixing ring and the pressing ring.

[0008] Preferably, the clamping member comprises a bent plate, a conical plate is fixedly connected to the lower end of the bent plate, and a strip-shaped through hole is provided on the bent plate.

[0009] Preferably, a smooth inclined surface is provided on one side of the conical plate close to the central axis of the main body, and the inclined surface faces upward.

[0010] Preferably, the driving mechanism includes a threaded rod that slides up and down and passes through the main body, the lower end of the threaded rod is provided with a slot, a connecting rod is fixedly connected in the slot, the connecting rod passes through the bar-shaped through hole, the threaded rod is externally threaded with a threaded sleeve, the threaded sleeve is rotatably connected to the upper end of the main body, and a plurality of rotating handles are fixedly connected to the outside of the threaded sleeve.

[0011] Preferably, the two clamping members are symmetrically arranged with respect to the center axis of the main body.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] By setting a driving mechanism, the supporting ring is placed around the nail, and then the rotating handle is rotated, the rotating handle drives the threaded sleeve to rotate, the threaded sleeve drives the threaded rod to rise and fall, the threaded rod drives the bending plate to deflect, and the bending plate drives the conical plate to rotate until the two conical plates clamp and fix the nail. At this time, the pressing ring is pressed, and the lower pressing handle is pinched with fingers to make it close to the upper pressing handle. In the process of the lower pressing handle moving upward, the pressing handle drives the fixing ring to rise, and the fixing ring drives the main body to rise. The main body drives the nail to rise through the fixing plate and the clamping member. The rising path coincides with the axial direction of the nail, the pulled out nail will not bend, and the nail hole will not become larger, which has a better effect on nail extraction.

[0014] When the utility model pulls out nails, the nail holes will not become larger, the nails will not bend, and the pulling out effect is better. BRIEF DESCRIPTION OF THE DRAWINGS
