The number of the lock hooks 31 is at least two, the lock hooks 31 are arranged at intervals relatively, each lock hook 31 comprises a hook body 35 and a shifting block 36, the hook bodies 35 are opposite in phase, one end of each hook body 35 protrudes out of the bottom of the accommodating seat 2, the other end of each hook body 35 is rotatably connected with the accommodating seat 2 through a rotating shaft, the other end of each hook body 35 and the shifting block 36 are integrally formed, an included angle is formed between the shifting block 36 and the hook body 35, therefore, the lock hooks 31 are approximately L-shaped, and the shifting blocks 36 are abutted to the guide pressing blocks 32. Wherein, the end of the pressure lever 33 abutting against the linkage mechanism 5 is provided with an inclined surface, and the inclined surface is a lower inclined surface 37. A second reset spring 34 is further disposed on the other side of the toggle block 36 opposite to the guide press block 32, one end of the second reset spring 34 abuts against the toggle block 36, and the other end abuts against the accommodating seat 2. When the interlocking mechanism 5 does not drive the lock mechanism 3 to operate, the second return spring 34 keeps the lock mechanism 3 in the locked state. When the locking mechanism 3 is driven by the linkage mechanism 5, the pressure lever 33 of the locking mechanism pushes the guide pressing block 32 to move towards the locking hook 31, at this time, the guide pressing block 32 presses the toggle block 36 connected with the hook body 35, so that the hook deflects by taking the rotating shaft connected with the accommodating seat 2 as a rotating fulcrum by the hook 35, the two hook bodies 35 approach each other until the two hook bodies are completely separated from the base 61 of the expander main body 6, that is, the expander main body 6 is unlocked and released from the accommodating seat 2. On the contrary, the hooking mechanism 3 can complete the locking and fixing of the expander body 6.

As shown in fig. 5 to 7, further, the linkage mechanism 5 includes a first pressing piece 51 and a second pressing piece 52 which are engaged with each other, wherein the first pressing piece 51 is used for driving the pressing ring 42, and the second pressing piece 52 is used for driving the pressing rod 33.

One end of the first pressing piece 51 is rotatably connected with the housing 1 through a shaft, the other end of the first pressing piece is a third extrusion end 56, the third extrusion end 56 is abutted against the press ring 42, an upper inclined surface 57 is arranged on the other side, opposite to the third extrusion end 56, of the first pressing piece 51, and the upper inclined surface 57 is abutted against the second extrusion end 54. Specifically, when the operating handle is used, the toggle end 55 drives the second pressing member 52 to move downward relative to the housing 1, and the first pressing end 53 presses the lower inclined surface 37 on the pressing rod 33, so that the pressing rod 33 is forced to push the guide pressing block 32 to move, and the unlocking of the locking mechanism 3 is realized; at this time, since the inclined surface of the first pressing member 51 abutting against the second pressing end 54 is the upper inclined surface 57, the second pressing member 52 cannot form a pressing force on the first pressing member 51 when moving downward relative to the housing 1. On the contrary, when the toggle end 55 drives the second pressing member 52 to move upward relative to the housing 1, the second pressing end 54 presses the upper inclined surface 57 of the first pressing member 51, so as to force the first pressing member 51 to push the press ring 42 to move, and further to realize the corresponding action of the restraint mechanism 4, similarly, the lower inclined surface 37 of the press rod 33 is opposite to the upper inclined surface 57 of the first pressing member 51, so that the locking mechanism 3 does not act at this time. That is, the operation control of the restraint mechanism 4 and/or the lock mechanism 3 by the link mechanism 5 is realized by the up-and-down movement of the dial end 55 with respect to the housing 1.

As shown in fig. 5-10, in a preferred embodiment, the dilator further comprises a restriction mechanism adjusting device, the restriction mechanism 4 adjusting device is used for adjusting the number of the restricted dilating valves on the dilator, the restriction mechanism 4 adjusting device comprises a toggle button 44 and a plurality of columns 45, one end of each column 45 is fixedly connected with the press ring 42, and the other end is a free end; the shifting key 44 is fixed with the pressing ring 42, the shifting key 44 extends out of the shell 1, and the pressing ring 42 can rotate relative to the accommodating seat 2; when the push ring 42 is pulled by the pull key 44 to rotate, the free end of part or all of the cylinders 45 is in contact with the slide bar 41. Specifically, as shown in fig. 8-10, in the present embodiment, the restriction mechanism adjusting device respectively has three steps, i.e., one step, two steps, and three steps, when the third step is reached, the pressing ring 42 is rotated, so that the end of each (four) sliding bar 41 abuts against one column, and at this time, when the pressing ring 42 is pushed in the axial direction of the accommodating seat 2, all the sliding bars 41 can extend out from the accommodating seat 2, and restriction on all (four) expansion flaps is realized; for another example, when the second gear is adjusted, the pressing ring 42 is rotated again, so that the end portions of three of the four sliding bars 41 abut against one column 45, and at this time, when the pressing ring 42 is pushed in the axial direction of the accommodating seat 2, the three sliding bars 41 can extend out of the accommodating seat 2, and the restriction on the three expansion lobes is realized; in the same way, when the first gear is adjusted, the compression ring 42 is rotated, so that the cylinder 45 is only abutted against two of the four slide bars 41, and only two expansion lobes are restrained. The restraint mechanism adjusting device is arranged, so that the flexibility of the phimosis prepuce expansion device in use can be effectively improved, for example, only three or two elastic expansion valves 62 in the expander main body 6 are used in a restraining manner, and the expansion force of the expander main body 6 can be reduced when the four expansion valves are used (participate in expansion), so that pain caused by overlarge expansion force can be avoided or reduced, and the expansion process can be gradually adapted or endured.
