DETAILED DESCRIPTION

[0023] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0024] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, an embodiment of the utility model provides a wall panel decoration nail puller: a gripping rod 1 is arranged on one side of a wall surface 20, a connecting shell 2 is fixedly connected to the upper surface of the gripping rod 1, a connecting rod 3 is arranged in the connecting shell 2, one end of the connecting rod 3 is fixedly connected to a threaded rod 1 4, the other end of the connecting rod 3 is fixedly connected to a threaded rod 2 5, the threaded rod 2 5 is rotatably connected to the inner wall of the connecting shell 2, the outer walls of the threaded rod 1 4 and the threaded rod 2 5 are threadedly connected with a clamping block 6, a wall top 19 is arranged between the two clamping blocks 6, the wall top 19 is connected to the wall surface 20, a spring 7 is sleeved on the outer wall of the connecting rod 3, the spring 7 is located between the two clamping blocks 6, and a cushion block 8 is fixedly connected to the lower bottom surface of the gripping rod 1.

[0026] In one embodiment, a threaded hole 9 is provided in the cushion block 8, and a slide groove 10 is provided on both sides of the cushion block 8. A support shell 11 is slidably connected in the slide groove 10, and a support plate 12 is fixedly connected to the end of the support shell 11 away from the cushion block 8. A slide groove 2 13 is provided in the support plate 12, and the grip 1 slides in the slide groove 2 13. A motor 14 is fixedly connected to the side of the support plate 12 close to the cushion block 8, and a threaded rod 3 15 is fixedly connected to the output end of the motor 14, and the threaded rod 3 15 is threadedly connected to the threaded hole 9.

[0027] In one embodiment, two support plates 16 are fixedly connected to both sides of the motor 14. The support plate 16 plays a supporting role, which facilitates the construction personnel to apply force to the support housing 11 and the support plate 1 12.

[0028] In one embodiment, the end of the threaded rod 14 away from the connecting rod 3 is fixedly connected with a handle 17, and the handle 17 is located outside the connecting shell 2. The handle 17 facilitates the construction personnel to rotate the threaded rod 14, so as to adjust the distance between the two clamping blocks 6. The end of the gripping rod 1 away from the wall top 19 is provided with a groove 18, and the number of the grooves 18 is multiple, and the multiple grooves 18 are evenly distributed on both sides of the gripping rod 1. The multiple grooves 18 increase the surface friction of the gripping rod 1. The thread directions of the threaded rod 14 and the threaded rod 25 are opposite.

[0029] When the utility model is in operation, the construction workers clamp the clamping block 6 to both sides of the wall top 19. At this time, the cushion block 8 is tilted, and the wall top 19 is used as a fulcrum to press down one end of the gripping rod 1 close to the groove 18, and the 19 part is pulled out under the action of the lever principle. When the cushion block 8 is close to the wall surface 20, the gripping rod 1 is continued to be pressed down with the bottom end of the cushion block 8 as a fulcrum, so that the wall top 19 is completely pulled out from the wall surface 20. When the specifications of the wall top 19 are different, the handle 17 is rotated, and the rotation of the handle 17 drives the connecting rod 3, the threaded rod 1 4 and the threaded rod 2 5 to rotate. Since the threaded rod 1 4 and the threaded rod 2 5 are respectively threadedly connected to the clamping block 6, the clamping block 6 moves on the threaded rod 1 4 and the threaded rod 2 5. Since the thread directions of the threaded rod 1 4 and the threaded rod 2 5 are opposite, the two clamping blocks 6 move toward each other on the threaded rod 1 4 and the threaded rod 2 5. The device is movable, thereby adjusting the spacing of the clamping block 6 according to the size of the wall top 19, making the device more practical; when the wall surface 20 is brittle, the support shell 11 and the cushion block 8 are assembled according to the shape and position of the threaded hole 9 and the slide groove 10, the clamping block 6 is clamped with the wall top 19, and the support plate 2 16 is pressed against the support plate 12 so that the support plate 12 and the support shell 11 are immobile, and the motor 14 is started. The motor 14 drives the threaded rod 3 15 to rotate. Since the threaded rod 3 15 is threadedly connected with the threaded hole 9 and the motor 14 and the threaded rod 3 15 are not displaced under the cooperation of the support shell 11, the cushion block 8 moves on the threaded rod 3 15, and under the cooperation of the slide groove 10 and the support shell 11, the cushion block 8 moves away from the wall surface 20 along the support shell 11, thereby removing the wall top 19 without causing damage to the wall surface 20.

[0030] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
