The ejector shaft mechanism 40 is a cross column structure, and the axis of the ejector shaft mechanism 40 is perpendicular to the midpoint of the central axis, that is, the ejector shaft mechanism 40 is perpendicular to the side of the handle body 10. The edges of the ejector shaft mechanism 40 are chamfered.
[0035] Based on the above structure, when in use, the shaft-pulling mechanism 20 is used to disassemble the shaft-shaped or block-shaped building blocks, and the first shaft-pulling arm 21 and the second shaft-pulling arm 22 are arranged oppositely to fix the two opposite sides of the shaft-shaped or block-shaped building blocks, and the building blocks are disassembled by clamping and pulling; the pin-pulling mechanism 30 is used to disassemble the open-hole building blocks, and the pin-pulling shaft 31 assists in positioning the pin hole and plays a certain supporting role. The first pin-pulling arm 32 and the second pin-pulling arm 33 on both sides cooperate with the pin-pulling shaft 31 to fix the open-hole building blocks, and the building blocks are disassembled by clamping and pulling; the ejection shaft mechanism 40 is used to disassemble the hole-shaped or cross-shaped building blocks, and the cross column structure is used to align the hole on the other side of the building block to eject it; the building block disassembler of this embodiment has newly added the functions of pulling shafts and ejecting shafts, which solves the problem of single function and can basically meet the disassembly of more complex building block models or buildings. The design with sharp edges is eliminated, and the edges are rounded to avoid stabbing or scratching the skin during use.

The specific structure and function of the third recess 321 and the fourth recess 331 are consistent with those of the first recess 211 and the second recess 221, and will not be repeated here, and those skilled in the art can know. In this embodiment, the first pin pulling arm 32, the second pin pulling arm 33 and the first shaft pulling arm 21 and the second shaft pulling arm 22 are symmetrically arranged at both ends of the handle body 10. An arc-shaped concave waist is formed in the middle of the handle body 10. The overall shape is smooth and flat without sharp protrusions. The size and length of the arc conform to the force analysis and are more labor-saving.
[0041] One end of the pin puller shaft 31 is fixed to the handle body 10, and the other end is formed with a cylindrical plug rod 311; the third clamping portion 322 and the fourth clamping portion 332 are both formed with auxiliary clamping steps 323 near the cylindrical plug rod 311, and the inner side of the auxiliary clamping steps 323 is provided with a semi-cylindrical groove. The cylindrical plug rod 311 is used to assist in positioning the pin hole, and the semi-cylindrical groove is adapted to the shape of the building block to increase the contact area with the building block.
[0042] The building block remover of this embodiment can be made of polycarbonate, nylon or ABS plastic through an injection molding process, and has the characteristics of durability, high strength, and light weight, and can protect the surface of the building blocks from damage during the disassembly process. The outer edges of the building block remover are all rounded to ensure that the edges and surfaces are smooth to prevent scratching the skin or damaging the building blocks. Although certain components and embodiments of the present application have been illustrated and described, many modifications and changes (for example, changes in the size, dimensions, structure, shape and proportion of each component, installation arrangement, material use, color, orientation, etc.) can be imagined by those skilled in the art without actually departing from the scope and spirit of the claims.
[0043] Finally, it should be noted that the above-mentioned implementation mode is only a preferred embodiment of the present utility model, and cannot be used to limit the scope of protection of the present utility model.
