Compared with the overall installation and disassembly, it saves time and effort.
[0003] In the process of implementing the present invention, the inventors found that there are at least the following problems in the prior art:
[0004] The design of the split shoe last makes it easier to remove the shoe last from the shoe after the shoe is made, reducing damage to the shoe during the last removal process. However, most of the current split shoe lasts are two-part lasts, as mentioned above, that is, the last body is divided into a front and a rear part. In actual applications, since the front part of the shoe body is generally longer, there is still inconvenience in removing the front part of the shoe last.
[0005] Therefore, the above technical problems need to be solved. Utility Model Content
[0006] In order to overcome the deficiencies of the prior art, the utility model provides a detachable shoe last, which solves the problem that most of the existing split shoe lasts are in two parts and it is still inconvenient to remove the front part of the shoe last.
[0007] In order to solve the above technical problems, the basic technical solution proposed by the utility model is:
[0008] A detachable shoe last comprises a front part of the last, a middle part of the last and a rear part of the last, and an assembly frame for assembling and supporting the three parts in sequence from front to back.

[0010] The assembly frame comprises a guide bar portion and a connecting rod portion which are distributed in the front and rear and connected in one piece. The top of the connecting rod portion is provided with a threaded seat for assembling the bottom end of the fixing column.
[0011] Preferably, the bottom of the middle part of the last is provided with a slide groove that is slidably matched with the guide bar part, and the top of the slide groove is provided with a reserved groove for the threaded seat to slide and accommodate. The threaded seat cooperates with the fixing column to realize the locking connection between the rear part of the last and the assembly frame, and the middle part of the last is slidably clamped in the middle part of the assembly frame. Preferably, in order to prevent the threaded seat from affecting the disassembly and assembly operation of the middle part of the last, a reserved groove for the threaded seat to slide and accommodate is provided on the top wall of the slide groove, so that the middle part of the last is not hindered by the threaded seat when sliding on the assembly.
[0012] Preferably, a clip strip is provided on the back of the middle part of the last, and a clip slot matching the clip strip is provided on the front of the rear part of the last. The provision of clip strips and clip slots matching each other can, on the one hand, help the positioning and assembly between the middle part of the last and the rear part of the last, and on the other hand, can further improve the reliability and stability of the connection between the two.
[0013] Preferably, the fixed column includes a column rod, and the bottom and top of the column rod are respectively fixedly mounted with a limit sleeve and a limit cap. The fixed column is a connecting piece between the rear part of the last and the assembly frame. Preferably, the limit cap and the limit sleeve are respectively arranged at the top and bottom of the column rod, so that the fixed column can be rotatably assembled on the rear part of the last. Compared with the traditional long screw, the column rod has only an external thread structure on the outer wall at the bottom, which is more convenient for disassembly and assembly.
[0014] Preferably, a handle is welded on the top of the limiting cap. The setting of the limiting sleeve and the limiting cap allows the column rod to be limitedly rotated and installed on the rear part of the last. Correspondingly, the handle is provided on the limiting cap, which helps to quickly remove the rear part of the last from the shoe body.
[0015] The beneficial effects of the utility model are:
[0016] The technical solution of the utility model is to split the shoe last into three parts, namely the front part of the last, the middle part of the last and the rear part of the last. Compared with the traditional two-section shoe last, each part is smaller in size and more convenient to take out. At the same time, the three parts are spliced together with the help of an assembly frame, ensuring the close connection and stability between the parts. BRIEF DESCRIPTION OF THE DRAWINGS
