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. Example

[0021] A detachable shoe last, such as Figure 1-Figure 4 As shown, it includes: a front end 1 of a shoe last and a rear end 2 of a shoe last, an embedded component is fixedly connected to one side of the front end 1 of the shoe last, and an insertion cavity 3 is provided at the rear end 2 of the shoe last. A clamping component for detachably connecting with the embedded component is slidably provided in the insertion cavity 3, and the connection and separation of the front end 1 of the shoe last and the rear end 2 of the shoe last are realized through the cooperation between the clamping component and the embedded component, and the insertion cavity 3 is provided with an opening one and an opening two, and the opening one is provided at the top of the rear end 2 of the shoe last so that one end of the clamping component extends to the outer side of the top of the rear end 2 of the shoe last through the opening one, and the user can control the clamping component conveniently through the opening one, and at the same time, an elastic support component for supporting the position of the clamping component is provided between the other end of the clamping component and the insertion cavity 3, and the elastic support component is used to provide elastic supporting force for the clamping component, so that the position of the clamping component is fixed in normal state to avoid arbitrary movement, thereby ensuring the connection stability between the clamping component and the embedded component.

[0022] like Figure 1-Figure 2 As shown, opening two is opened at the bottom of the rear end 2 of the shoe last, so that the embedding component can be embedded into the insertion cavity 3 through opening two from bottom to top along the height direction of the shoe last. Therefore, when the shoe last is taken out after use, it is convenient to take out the rear end 2 of the shoe last first, and then take out the front end 1 of the shoe last to reduce the problem of tearing the upper, causing deformation and tearing of the upper.

[0023] In addition, a notch 6 for accommodating the embedded component is provided at the second opening position of the shoe last rear end 2, and the notch 6 provides a placement space for the embedded component of the shoe last front end 1, thereby ensuring the connection stability after the shoe last front end 1 and the shoe last rear end 2 are connected.

[0024] Among them Figure 1 and Figure 3 As shown, the embedding component includes a base 7 fixedly connected to the front end 1 of the shoe last and an embedding piece 8 fixedly connected to the base 7 for embedding the snap-in component. The snap-in component includes a moving piece 9 slidably arranged in the insertion cavity 3 and a snap-in piece 10 slidably arranged on the moving piece 9. A slot 11 for embedding the embedding piece 8 is opened on the moving piece 9. One end of the snap-in piece 10 is embedded in the slot 11, and an elastic element 12 is arranged between the other end and the moving piece 9. Therefore, during the process of embedding the embedding piece 8 into the slot 11, the embedding piece 8 will abut against the snap-in piece 10 and push the snap-in piece 10 to move toward the elastic element 12. Then, after the embedding piece 8 is separated from the snap-in piece 10, the elastic element 12 releases the elastic thrust to push the snap-in piece 10 to reset its position, so that the snap-in piece 10 limits the embedding piece 8 to withdraw. At the same time, the base 7 and the rear end 2 of the shoe last complement the notch 6, so that the front end 1 of the shoe last and the rear end 2 of the shoe last are fixed to ensure the stability of the overall structure.

[0025] At the same time Figure 3 As shown, a snap-in area 13 is provided at one end where the base 7 is connected to the insert 8, so that when the insert 8 is inserted into the slot 11, the insert 8 pushes the snap-in 10 to exit the slot 11; after the insert 8 is separated from the snap-in 10, the snap-in 10 is embedded in the snap-in area 13, and the snap-in area 13 is used to enhance the connection firmness with the snap-in 10.

[0026] A retraction member 14 is slidably provided on the clamping area 13 for pushing the clamping member 10 to exit the clamping area 13, so that when the movable member 9 continues to move toward the embedded member 8, the clamping member 10 abuts against the retraction member 14 to exit the clamping area 13, thereby releasing the position restriction of the embedded member 8, thereby realizing the separation of the front end 1 of the shoe last and the rear end 2 of the shoe last. Therefore, when the shoe last is to be taken out, it is also convenient to take out the rear end 2 of the shoe last first, and then take out the front end 1 of the shoe last to reduce the problem of tearing the shoe upper, which causes deformation and tearing of the shoe upper.

[0027] The insert 8 is configured as a frustum of a cone structure, and the inclined side wall of the frustum of a cone structure is used to abut against the clip 10. When the inclined side wall of the frustum of a cone structure abuts against the clip 10, a component force is formed on the clip 10 to push the clip 10 to move. At the same time, the clip 10 is provided with an inclined surface for abutting against the side wall of the frustum of a cone structure, and the efficiency of movement is further enhanced by utilizing the inclined surface.

[0028] The return member 14 is configured as an annular structure and is sleeved on the base 7, so that the return member 14 can move freely in the clamping area 13. At the same time, two symmetrically arranged inclined surfaces are provided on the side of the annular structure that contacts the clamping member 10, so that the annular structure is divided into an upper half and a lower half by the two inclined surfaces, so that when the movable member 9 continues to move toward the embedded member 8, the clamping member 10 will abut against the inclined surface of the upper half, and the inclined surface is used to push the clamping member 10 again to move toward the direction of the elastic element 12, and then when the clamping member 10 abuts against the inclined surface of the lower half, the elastic element 12 releases the elastic thrust to push the clamping member 10 to move outward, and then the clamping member 10 forms a thrust with the inclined surface of the lower half to push the return member 14 upward, so that the clamping member 10 is located below the return member 14.

[0029] Then pull the moving part 9 upward, so that the clamping part 10 pushes the retracting part 14 to move upward together. At the same time, a groove 16 for embedding the retracting part 14 is provided on the side of the embedding part 8 close to the retracting part 14. The depth of the groove 16 is equal to half the height of the annular structure. Then the retracting part 14 is embedded in the groove 16, and the position of the retracting part 14 is fixed. At this time, the moving part 9 continues to move upward, and the clamping part 10 retreats along the guidance of the inclined surface of the lower half of the retracting part 14.

[0030] like Figure 2 As shown, the elastic support assembly includes a telescopic rod 5 and an elastic element 4 whose two ends are respectively abutted against the clamping assembly and the side wall of the insertion cavity 3. The two ends of the telescopic rod 5 are respectively connected to the clamping assembly and the insertion cavity 3. The elastic element 4 is sleeved on the outside of the telescopic rod 5. The telescopic rod 5 limits the moving distance of the clamping assembly to prevent the clamping assembly from falling off, and the elastic element 4 provides elastic supporting force for the clamping assembly to ensure that the position of the clamping assembly is fixed under normal conditions.

[0031] like Figure 2 and Figure 4 As shown, the moving member 9 extends to one side of the top of the rear end 2 of the shoe last and is rotatably provided with a blocking member 15, so that the blocking member 15 can be rotated at different angles to control whether the blocking member 15 passes through the opening 1, thereby avoiding the occurrence of accidental touch.

[0032] Working principle: After the shoe last is used, the rotating blocking member 15 pushes the moving member 9 to move downward, so that the clamping member 10 abuts against the inclined surface of the upper half of the retracting member 14, and the clamping member 10 retreats along the guiding direction of the inclined surface. Then, after the clamping member 10 moves to the end of the inclined surface of the upper half, the clamping member 10 has completely withdrawn from the slot 11, and the moving member 9 continues to move downward, so that the clamping member 10 abuts against the inclined surface of the lower half of the retracting member 14, and the clamping member 10 re-enters the slot 11. And it is embedded in the clamping area 13, and then the moving part 9 is pulled upward, so that the clamping part 10 pushes the retracting part 14 to move upward accordingly. After the retracting part 14 is embedded in the groove 16, its position is fixed. At this time, the moving part 9 continues to move upward, so that the clamping part 10 is retreated along the guidance of the inclined surface of the lower half of the retracting part 14, so that the clamping part 10 transitions to the inclined side wall of the frustum structure of the insert 8. After further movement, the clamping part 10 is separated from the insert 8, thereby realizing the separation of the front end 1 of the shoe last and the rear end 2 of the shoe last.
