When the carrier is fixed to the shoe tree 7, the fixing steel balls 32 are clamped between the outer wall of the moving rod 33 and the inner wall of the first connecting hole 73, and the connecting seat 72 is fixed; when the carrier is disconnected from the shoe tree 7, the moving rod 33 moves downward, so that the arc-shaped fixing groove 34 is opposite to the plurality of fixing steel balls 32, at this time, the fixing steel balls 32 can move inward into the arc-shaped fixing groove 34, the connection between the fixing steel balls 32 and the connecting seat 72 is released, and then the connection between the carrier and the shoe tree 7 is released.
[0029] The driving assembly 5 comprises a push plate 51 arranged in the mounting base 2 and movable in the transverse direction, two first moving wheels 52 arranged opposite to the lower end of the moving rod 33, a first moving hole 53 arranged on the push plate 51 and extending in the moving direction of the push plate 51, two first limiting grooves 54 arranged on both sides of the first moving hole 53 and capable of cooperating with the first moving wheels 52, and a plurality of guide wheels arranged in the moving direction of the push plate 51 and capable of guiding the movement of the push plate 51. The first limiting groove 54 comprises a first arc-shaped limiting part 541 capable of being embedded in the first moving wheel 52 and a first guide surface 542 arranged on the left side of the first arc-shaped limiting part 541 and extending upward in the moving direction of the push plate 51. When the first moving wheel 52 moves into the first arc-shaped limiting part 541, the moving rod 33 moves upward to the highest position, at this time, the fixing steel balls 32 are clamped between the outer wall of the moving rod 33 and the inner wall of the first connecting hole 73, and the connecting seat 72 is fixed. When the push plate 51 moves to the right, the first moving wheel 52 moves to the left along the first guide surface 542 and drives the moving rod 33 to move downward to the lowest position, at this time, the fixing steel balls 32 are opposite to the arc-shaped fixing groove 34 and move inward into the arc-shaped fixing groove 34, and the connection between the fixing steel balls 32 and the connecting seat 72 is released.
[0030] The mounting base 2 includes a first base 21 disposed on the base plate 12, a second base 22 extending upward from the first base 21, and a connecting pin 23 disposed between the first base 21 and the second base 22.

The second base 22 has a second movable cavity 221 opposite to the first movable cavity 212 for the upper end of the moving rod 33 to move. The top surface of the second base 22 has a mounting groove 222 extending downward for mounting the connecting seat 72, and a fixing post 31 is disposed at the upper end of the second movable cavity 221. Furthermore, the mounting base 2 also includes a connecting sleeve 24 connecting the first movable cavity 212 and the second movable cavity 221. The lower end of the moving rod 33 passes through the connecting sleeve 24 and the first movable cavity 212 in sequence into the movable cavity 211.
[0031] The first reset member 35 includes a first reset hole 351 disposed on the base plate 12 opposite to the lower end of the moving rod 33 and a first reset spring 352 disposed in the first reset hole 351 and connected to the lower end of the moving rod 33. The lower end of the first reset spring 352 is connected to the bottom surface of the first reset hole 351 and the upper end is connected to the lower end of the moving rod 33. When the moving rod 33 moves downward, it will squeeze the first reset spring 352. The squeezed first reset spring 352 can move upward and reset when the push plate 51 loses the external force, so that the moving rod 33 moves upward and resets, and the push plate 51 moves to the left and resets.
[0032] The push plate 51 includes a push plate body 511 disposed in the movable cavity 211 and a push part 512 connected to one end of the push plate body 511 and extending to the left to the outside of the mounting base 2, wherein the first moving hole 53 is disposed on the push plate body 511.
[0033] Multiple guide wheels include four first upper guide wheels 55 arranged in a matrix and in contact with the top surface of the push plate 51, and two first lower guide wheels 56 arranged opposite each other on both sides of the push plate 51 and in contact with the bottom surface of the push plate 51. The pushing part 512 is vertically opposite to the first lower guide wheels 56. The arrangement of multiple guide wheels guides the movement of the push plate 51, so that the moving rod 33 moves up and down stably.
[0034] The guide 6 is arranged in the first seat body 21 and located at one side of the moving rod 33, and comprises a guide column 61 arranged in the first seat body 21 and moving up and down, two second moving wheels 62 arranged oppositely at lower ends of the guide column 61, a second moving hole 63 arranged on the push plate 51 and extending along a moving direction of the push plate 51 for the guide column 61 to pass through, two second limiting grooves 64 arranged at two sides of the second moving hole 63 respectively and capable of cooperating with the second moving wheels 62 oppositely, and a second reset member 65 arranged between the guide column 61 and the mounting seat 2. Specifically, the second limiting groove 64 comprises a second arc-shaped limiting part 641 capable of being embedded with the second moving wheel 62 oppositely and a second guide surface 642 arranged at a left side of the second arc-shaped limiting part 641 and extending upwardly and obliquely along the moving direction of the push plate 51. The second moving hole 63 is arranged on the push plate 51 and spaced leftward and rightward from the first moving hole 53, so that the push plate 51 can drive the guide column 61 and the moving rod 33 to move downward simultaneously. Further, the second reset member 65 has the same structure as the first reset member 35, and the specific structure and working principle of the second reset member 65 will not be described further.
[0035] When the shoe tree 7 is installed, the push plate 51 is first pushed rightward, and under the cooperation of the first moving wheel 52 and the first limiting groove 54 and the second moving wheel 62 and the second limiting groove 64, the moving rod 33 and the guide column 61 are driven to move downward simultaneously, so that the fixed steel ball 32 moves inwardly into the arc-shaped fixed groove 34, and then the first connecting hole 73 and the second connecting hole 74 on the shoe tree 7 are arranged oppositely with the fixed column 31 and the positioning column 4 respectively. At this time, the push plate 51 can be loosened, and under the action of no external force, the first reset member 35 and the second reset member 65 drive the moving rod 33 and the guide column 61 to move upward and reset respectively. In the process of the moving rod 33 moving upward and resetting, the fixed steel ball 32 moves outwardly, and then is clamped between the inner wall of the first connecting hole 73 and the outer wall of the moving rod 33, so that the installation and fixation of the shoe tree 7 are completed.
[0036] The application limits the structural composition of the carrier, the moving rod 33 moving up and down through the cooperation of the fixed steel ball 32 and the arc-shaped fixed groove 34, so that the fixed steel ball 32 can be fixed between the inner wall of the first connecting hole 73 and the outer wall of the moving rod 33 to fix the shoe tree 7, or the fixed steel ball 32 can move inwardly into the arc-shaped fixed groove 34 to release the fixation of the shoe tree 7. The whole operation is simple, and under the action of no external force, the fixed steel ball 32 will not move inwardly into the arc-shaped fixed groove 34, so as to ensure the stability of the fixation of the shoe tree 7. Further, the structure of the driving assembly 5 is limited, and through the cooperation of the transversely moving push plate 51, the first limiting groove 54 and the first moving wheel 52, the moving rod 33 can move up and down, and the transverse movement of the push plate 51 can be realized by manpower, without the need of using complex power. In the case of power failure and fault, the application can still be used.
[0037] The above merely describes preferred embodiments of the present application, and therefore cannot limit the scope of the present application, i.e. equivalent changes and modifications made according to the scope of the present application and the content of the specification shall still belong to the scope of the present application.
