The sensor 103 is a Hall sensor 103 or a photoelectric sensor 103, and the multi-faceted body 104f is provided with a magnet or light-blocking block that cooperates with it for providing a flipping position feedback signal to the control circuit. A limit structure is provided between the outer shell 101 and the base 100 to limit the downward stroke of the outer shell 101, and to work with the spring 102 to achieve automatic reset after the stamping is completed.

[0026] The multi-face seal 104 comprises a rotating motor 104a arranged in the shell 101 and fixed on both sides by a mounting plate 104b, a rotating gear 104c connected to the output shaft of the rotating motor 104a, an inner tooth ring 104d arranged outside the rotating gear 104c, a plurality of driven gears 104e arranged between the rotating gear 104c and the inner tooth ring 104d, for realizing the rotation of the inner tooth ring 104d driven by the rotating gear 104c, one side of the inner tooth ring 104d is fixedly connected with a polyhedron 104f, the rotating motor 104a drives the rotating gear 104c and drives the inner tooth ring 104d to rotate through the driven gears 104e, and drives the polyhedron 104f to overturn, each face of the polyhedron 104f is provided with a seal template 104g with different patterns. The polyhedron 104f is a regular polyhedron 104f structure, specifically a regular tetrahedron, a regular hexahedron or a regular octahedron, and the angle of each overturning is a fixed angle, so as to ensure that each seal template is sequentially presented at the seal outlet end. The connection between the polyhedron 104f and the seal template 104g is detachable connection. The detachable connection includes buckle, quick release pin, threaded sleeve and any structure that can quickly separate and install the seal template 104g and the polyhedron 104f without additional tools or only simple operation.

[0027] A dismounting piece 105 is further arranged between the base 100 and the multi-face seal 104, the dismounting piece 105 comprises a U-shaped opening slot arranged on the base 100 in the vertical direction, a clamping block 105a is slidably arranged above the U-shaped opening slot, a ∩-shaped opening slot is arranged at the bottom of the clamping block 105a and corresponds to the U-shaped opening slot, and the U-shaped opening slot and the ∩-shaped opening slot form a closed sliding channel for accommodating and limiting the protruding part of the mounting plate 104b.

[0028] The shell 101 is provided with a mounting through hole 106 aligned with the sliding channel, and a positioning sleeve 107 is arranged in the mounting through hole 106 and sleeved on the protruding part of the mounting plate 104b. The positioning sleeve 107 is used to connect the shell 101 and the multi-face seal 104 as a whole. When the multi-face seal 104 is replaced, the positioning sleeve 107 is pulled out of the protruding part of the mounting plate 104b and the mounting through hole 106, so that the shell 101 can be separated.

[0029] The surface of the positioning sleeve 107 in contact with the protruding part of the mounting plate 104b and the mounting through hole 106 is a special-shaped structure. In this embodiment, the surface of the positioning sleeve 107 in contact with the protruding part of the mounting plate 104b and the mounting through hole 106 is a runway-shaped structure.

[0030] The clamping block 105a is connected with the base 100 through a connecting member. In this embodiment, the clamping block 105a is connected with the base 100 through a bolt. The clamping block 105a is connected with the base 100 through the bolt, so that the base 100 and the multi-face seal 104 are connected as a whole. When the multi-face seal 104 is replaced, the shell 101 is separated, the clamping block 105a is separated from the base 100 through the bolt, the base 100 is separated from the multi-face seal 104, and the multi-face seal 104 is replaced.

[0031] The rotating motor 104a is electrically connected with a control circuit. The control circuit is used to control the motor to drive the polyhedron 104f to rotate by a preset angle. The control circuit is also connected with a position detection sensor 103, which is used to detect the position of the seal template 104g where the polyhedron 104f is currently located.

[0032] Working principle: When the shell 101 is pressed, the shell 101 slides downward along the vertical direction, the seal template below the shell 101 contacts the printing target, and a printing operation is completed. After the shell 101 is pressed, the spring 102 arranged between the base 100 and the shell 101 starts to compress. After the printing is completed, the return force of the spring 102 pushes the shell 101 back to the initial position. The sensor 103 continuously monitors the displacement of the shell 101. According to the feedback information of the sensor 103 and the preset control program, the control circuit instructs the driving mechanism connected with the rotating motor 104a to work. The rotating motor 104a drives the rotating gear 104c to rotate by a preset fixed angle under the instruction of the control circuit. The rotating gear 104c drives the inner tooth ring 104d on the outer side to rotate through the driven gear 104e. The inner tooth ring 104d is fixedly connected with the regular polyhedron 104f, such as a regular tetrahedron, a regular hexahedron or a regular octahedron. Therefore, the polyhedron 104f is rotated to the predetermined position of the next seal template 104g, so that the seal templates 104g can be arranged in sequence and presented at the seal outlet end.

[0033] When the multi-face seal fails or needs to be replaced by a set of overprint seal, the positioning sleeve 107 is first pulled out to be separated from the protruding part of the mounting plate 104b and the mounting through hole 106 of the shell 101, so that the shell 101 is separated from the base 100 and the multi-face seal 104. Then, the base 100 is further separated from the clamping block 105a by disassembling the bolt, and the multi-face seal 104 can be replaced.

[0034] When only the stamp template 104g needs to be replaced or updated, loosen the detachable connection (such as buckle, quick release pin or threaded sleeve) between the polyhedron 104f and the stamp template 104g; remove the old stamp template 104g from the polyhedron 104f; align the new stamp template 104g with the corresponding face of the polyhedron 104f, press or screw the detachable connection until it is clamped in place, and the quick replacement of a single template is completed.
