Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] Split shoe last, such as Figure 1-Figure 5 As shown, it includes a front end 1 of the shoe last and a rear end 2 of the shoe last, and a split structure is formed by the front end 1 of the shoe last and the rear end 2 of the shoe last, so that local components can be replaced according to the damage of the front end 1 of the shoe last and the rear end 2 of the shoe last, so as to recycle resources, wherein a latch hole 17 for cooperating with a manipulator or a fixing device is provided at the top position of the rear end 2 of the shoe last, and the normal use of the split shoe last is ensured by the latch hole 17, and a receiving cavity 3 is also provided in the front end 1 of the shoe last, and an opening 4 is provided on one side of the receiving cavity 3 close to the rear end 2 of the shoe last, and a latch hole 17 for passing through the rear end 2 of the shoe last is provided on the rear end 2 of the shoe last. The clamping part 5 of the opening 4 is slidably provided with a driving component on the rear end 2 of the shoe last for pushing the clamping part 5 to rotate, and one end of the driving component extends to the outside of the rear end 2 of the shoe last; the driving component drives the clamping part 5 to rotate so that the clamping part 5 abuts against the inner wall of the accommodating cavity 3 to fix the connection between the front end 1 of the shoe last and the rear end 2 of the shoe last. Then, if the connection between the front end 1 of the shoe last and the rear end 2 of the shoe last needs to be released, the connection can be released by pushing the driving component in the reverse direction, so that the user can replace the front end 1 of the shoe last and the rear end 2 of the shoe last according to the damage of the shoe last, thereby achieving the effect of recycling resources.

[0026] like Figure 2-Figure 4 As shown, the clamping part 5 includes a rotating part 6 rotatably connected to the rear end 2 of the shoe last and a clamping part 7 fixedly connected to the rotating part 6. The rotating part 6 is connected to a driving component, and the driving component drives the rotating part 6 to rotate, thereby driving the clamping part 7 to rotate, so that the clamping part 7 is misaligned with the opening 4, thereby achieving an effect of the clamping part 7 abutting against the inner wall of the accommodating cavity 3.

[0027] like Figure 2-Figure 3As shown, the driving assembly includes an insert 8 and a displacement member 9 slidably arranged on the rear end 2 of the shoe last, one end of the displacement member 9 extends to the outside of the rear end 2 of the shoe last, so that the displacement member 9 can be driven to move by the extended end of the displacement member 9, and a through hole 10 for the rotating part 6 to pass through is opened on the displacement member 9, the insert 8 is fixedly arranged on the inner wall of the through hole 10, and one end of the insert 8 is embedded in the rotating part 6, and a cam groove 11 for the insert 8 to be embedded is provided on the outer side wall of the rotating part 6, so that during the movement of the displacement member 9, the insert 8 abuts against the side wall of the cam groove 11 to push the rotating part 6 to rotate.

[0028] like Figure 2-Figure 3 As shown, a positioning assembly is provided on the side of the displacement member 9 near the front end 1 of the shoe last at the rear end 2 of the shoe last, and the positioning assembly includes a positioning block 12 that moves along the height direction of the rear end 2 of the shoe last and an elastic element 13 that pushes the positioning block 12 to move toward the top position of the rear end 2 of the shoe last. An outer edge 14 is fixedly provided on one end of the displacement member 9 extending to the outside of the rear end 2 of the shoe last, and the positioning block 12 is located on the moving path of the outer edge 14; thereby, the movement of the displacement member 9 is limited by the positioning block 12, so that the position of the displacement member 9 is fixed in the normal state, so that when the outer edge 14 moves toward the direction close to the positioning block 12, it is necessary to press the positioning block 12 downward to provide moving space for the displacement member 9, so that the displacement member 9 can move, and under the elastic thrust of the elastic element 13, the positioning block 12 moves toward the original position, so that abutment effect is formed between the positioning block 12 and the displacement member 9, thereby fixing the position of the displacement member 9 after displacement, thereby achieving a good positioning effect.

[0029] like Figure 3 As shown, at the same time, a through groove 15 for embedding the positioning block 12 is opened on one side of the outer edge 14 close to the elastic element 13, so that after the displacement member 9 is displaced to a suitable position, the position of the through groove 15 will coincide with the position of the positioning block 12, thereby prompting the user to move and adjust the suitable position. And under the elastic thrust of the elastic element 13, the positioning block 12 can return to its original position through the through groove 15, avoiding the elastic element 13 from being in a compressed state for a long time.

[0030] like Figure 2-Figure 4 As shown, the positioning block 12 is arranged as a step structure, and the rear end 2 of the shoe last is arranged with a necking structure matching with the step structure, and the positioning block 12 is prevented from falling off from the rear end 2 of the shoe last by the cooperation between the necking structure and the step structure.

[0031] like Figure 1-Figure 3 As shown, a force application groove 16 is provided on one end of the displacement member 9 extending to the outside of the rear end 2 of the shoe last. The force application groove 16 provides a force application point, thereby facilitating the user to apply external force to the displacement member 9 to drive it to move.

[0032] Working principle: When the rear end 2 of the shoe last is damaged, the positioning block 12 is pressed downward through the through groove 15 to release the fixing effect on the position of the displacement member 9, and then the displacement member 9 is pulled to move through the force groove 16, so that the through groove 15 and the positioning block 12 are misaligned with each other. As the displacement member 9 moves, the embedded member 8 on the displacement member 9 pushes the rotating part 6 to rotate through the cam groove 11, so that the clamping part 7 corresponds to the position of the opening 4, and then the front end 1 of the shoe last and the rear end 2 of the shoe last are pulled away from each other, so as to separate the front end 1 of the shoe last and the rear end 2 of the shoe last, and then the front end 1 of the shoe last can be connected to the rear end 2 of the new shoe last to realize the recycling of the front end 1 of the shoe last.
