Description

Technical Field

[0001] The present application relates to the field of decoration tools, and more specifically, to a nail puller for building decoration that is easy to adjust. Background Art

[0002] Building decoration refers to beautifying and improving the external appearance or internal environment of objects such as houses, bridges, stadiums, temples, etc. built with building materials such as stones and woods for people to live in and use. During decoration, iron nails are needed to fix the materials, and after the decoration is completed, a nail puller is required to remove the iron nails. The patent document with the publication number CN220463772U in the prior art provides a nail puller for building decoration. This device can accurately adjust the distance between the two nail-lifting plates according to the actual size of the nails, so that the nail puller for building decoration can pull out nails with more diameters, expanding the applicable range of the nail puller for building decoration, improving the practicability and structural flexibility of the nail puller for building decoration, and facilitating the replacement of the nail-lifting plate when the nail-lifting plate is damaged.

[0003] Regarding the above related technologies, the inventor believes that currently, the nail puller mainly uses the lever principle. On the one hand, when prying, the nail puller needs to reserve a movable space, resulting in inapplicability in a narrow environment. On the other hand, when the nail puller is stressed, the material in contact will be damaged. Therefore, we propose a nail puller for building decoration that is easy to adjust. Utility Model Content

[0004] To improve the problems proposed in the above background art, the present application provides a nail puller for building decoration that is easy to adjust.

[0005] A nail puller for building decoration that is easy to adjust provided by the present application adopts the following technical solutions:

[0006] A nail puller for building decoration that is easy to adjust includes a fixing plate. A nail-pulling member is arranged inside the fixing plate. One end of the nail-pulling member is provided with a nail-clamping hole. Both symmetric sides of the nail-pulling member are connected to the fixing plate through folding rods. Two operating rods are hinged on the fixing plate. The operating rods are in abutting cooperation with the folding rods. A plurality of support rods are rotatably connected to the fixing plate at equal intervals in a circular shape. One end of the support rod is movably connected to a support plate, and the other end is fixedly connected to a gear. One side of the gear is meshed with a rack. The rack is slidably connected to the fixing plate, and a driving ring is rotatably connected to one side of the fixing plate. The driving ring is used to drive the rack to slide.

[0007] By adopting the above technical solution, after the nail hole is clamped with the iron nail to be pulled out, multiple support plates cooperate to abut against the material connected to the iron nail. When the two operating rods are driven to rotate closer, the operating rods cause the folding rods to extend, and the folding rods drive the nail pulling member to move, so that the nail pulling member drives the iron nail to be pulled out straight from the material.

[0008] Optionally, the folding rod is composed of two connecting rods hinged to each other. One connecting rod is hinged to the fixed plate, and the other connecting rod is hinged to the nail pulling member.

[0009] By adopting the above technical solution, when the operating rod rotates and abuts against the folding rod, the two folding rods extend and cooperate to drive the nail pulling member to translate, so that the nail pulling member drives the iron nail to be taken out of the material.

[0010] Optionally, a guide wheel is rotatably connected to the hinged part of the two connecting rods, and the guide wheel is in rolling contact with the operating rod.

[0011] By adopting the above technical solution, when the two operating rods rotate closer, cooperating with the guide wheel can reduce the frictional resistance, so that the folding rod extends to drive the nail pulling member to move.

[0012] Optionally, a ball head is fixedly connected to one end of the support rod, and a limit seat is rotatably connected to the ball head, and the limit seat is fixedly connected to the support plate.

[0013] By adopting the above technical solution, the cooperation between the ball head and the limit seat enables the support plate to be adjusted in multiple directions, so that multiple support plates can cooperate to effectively contact the material, avoiding damage to the material during nail pulling.

[0014] Optionally, a spiral bar is fixedly connected to one side of the driving ring, and a sliding groove adapted to the spiral bar is provided on one side of the rack.

[0015] By adopting the above technical solution, when the driving ring is rotated, the cooperation between the spiral bar and the sliding groove can drive the rack to move. When the rack moves, it drives the gear to rotate, so that multiple support rods can cooperate to rotate, thereby driving the support plate to effectively contact the material.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. When the rack is driven to move by the rotating ring, the gear drives the support rod to rotate, so that multiple support plates can effectively contact the material. When the two operating rods are driven to rotate closer to each other, the operating rods abut against the folding rods to drive the nail pulling member to translate, so that the nail pulling member pulls out the iron nail in the material. The operation space is small and the material is not damaged, and the practicability is good.

[0018] 2. When the folding rod extends, it drives the nail pulling piece to translate, so that the iron nails pulled out by the nail pulling piece are not affected by deformation, and thus can be reused, reducing the decoration cost and further improving the practicability.
