[0036] The connecting plate 15 is located at an inner end surface of the upper end shell 12 and a matching plate 16 is fixedly provided thereon. An insertion hole 17 is provided on the matching plate 16 .

[0037] A spring upper fixing plate 18 is fixedly provided at the top of the internal space of the upper end shell 11, a support frame 19 is fixedly provided at the lower side of the spring upper fixing plate 18, a vertical rod 20 is provided on the support frame 19, and the vertical rod 20 is arranged on both sides of the support frame 19, the vertical rod 20 is used to abut against the spring upper fixing plate 18, and a connecting block 21 is fixedly provided at the lower side of the support frame 19.

[0038] A accommodating frame 25 is fixedly provided on the lower side of the spring upper fixing plate 18, and the accommodating frame 25 is used to install the electromagnetic lock 22. The electromagnetic lock 22 is provided with a pin 24. When the electromagnetic lock 22 is locked, the pin 24 will be pushed out, and when the electromagnetic lock 22 is not locked, the pin 24 will shrink. A lock buckle 23 is provided on the supporting frame 19, and a slope is provided on the upper side of the lock buckle 23 to prevent the lock buckle 23 from directly colliding with the accommodating frame 25 when moving up and down. A lock buckle locking hole is provided on the lock buckle 23, and the lock buckle locking hole is arranged corresponding to the pin 24. When the lock buckle 23 rises to the extreme position, the lock buckle locking hole is aligned with the pin 24. At this time, the electromagnetic lock 22 pushes the pin 24 to be inserted into the lock buckle locking hole after being locked.

[0039] The support frame 19 is also provided with a steering gear 26, the driving rod of the steering gear 26 is arranged downward, and the steering gear 26 is used to provide clockwise and counterclockwise circumferential rotational force, and the lower side of the steering gear 26 drives the shaft.

[0040] A sliding tongue lock 27 is provided between the support frame 19 and the connecting block 21. The tongue locks 27 are symmetrically arranged. A rack is provided on the inner side surface between the symmetrical tongue locks 27. The driving shaft extends downward. A gear 18 is fixedly provided on the driving shaft between the symmetrical tongue locks 27. The gear 18 is meshed with the rack on the inner side of the symmetrically arranged tongue locks 27. When the steering gear drives the driving shaft to rotate, the driving shaft drives the rack 18 to rotate. The gear 18 rotates and then cooperates with the rack to cause the symmetrical tongue locks 27 to slide in relative directions, that is, the symmetrically arranged tongue locks 27 slide outward in two symmetrical directions respectively.

[0041] Connecting ejector pins 28 are fixedly provided at both ends of the tongue lock 27. When the tongue lock 27 slides outward under the drive of the gear 18, the tongue lock 27 carries the connecting ejector pins 28 to slide outward synchronously, and the connecting ejector pins 28 slide outward to cooperate with the matching plate 16, and the connecting ejector pins 28 slide outward to be inserted into the insertion holes 17 of the matching plate 16.

[0042] A support plate 35 is fixedly provided on the lower side of the inner part of the connecting block 21, and a buckle plate 29 is slidably provided between the support plate 35 and the connecting block 21. Fastener holes 30 are provided on both sides of the buckle plate 29, and a pushing hole 32 is provided between the fastener holes 30. A lock rocker arm 32 is fixedly provided on the driving shaft extending into the pushing hole 32, and a lock rocker arm swing block 33 is provided on the lock rocker arm 32. A buckle plate boss 34 is fixedly provided on the side of the pushing hole 32, and the buckle plate boss 34 is used to cooperate with the swing arm swing block 33. When the driving shaft drives the lock rocker arm 32 to rotate, the lock rocker arm 32 drives the lock rocker arm swing block 33 to rotate, and the lock rocker arm swing block 33 rotates to contact the buckle plate boss 34, and further drives the buckle plate 29 to slide by pushing the buckle plate boss 34.

[0043] A spring 36 is also provided at one end of the pinch plate 29 , and the elastic force of the spring 36 is used for the rebound of the pinch plate 29 .

[0044] The support plate 35 is provided with a clamp support plate 37 at the lower side, and a buckle 38 is provided on the clamp support plate 37. The position of the buckle 38 is set corresponding to the fastener hole 30. The upper side cross-section of the buckle 38 is a buckle with a trapezoidal or triangular structure and a gradually convex structure with an inclined surface. After the buckle 38 extends into the fastener hole 30, the buckle plate 29 abuts against the side of the buckle 38 under the action of a spring. Since the upper side of the buckle 38 will be pressed against the top surface of the buckle plate 29, the buckle 38 cannot fall at this time, thereby completing the locking action of the buckle 38 and the buckle plate 29.

[0045] When the lock rocker arm 32 drives the lock rocker arm swing block 33 to rotate, the lock rocker arm swing block 33 rotates to contact the buckle plate boss 34, and further drives the buckle plate 29 to slide by pushing the buckle plate boss 34. At this time, the buckle plate 29 is separated from the buckle 38, and the buckle plate 29 no longer hinders the buckle 38 from descending. At this time, the buckle 38 can freely separate from the buckle plate 29.

[0046] The lower side of the spring upper fixing plate 18 is provided with a top hook 39, and preferably two top hooks 39 are provided, and the two top hooks 39 are preferably provided diagonally.

[0047] A bottom hook 40 is provided on the top surface of the connecting block 21 , and the bottom hook 40 is preferably provided in two numbers, and the two bottom hooks 40 are preferably provided diagonally, the top hook 39 is provided corresponding to the position of the bottom hook 40 , and a tension spring 41 is provided between the top hook 39 and the bottom hook 40 .

[0048] The lower side of the clamp support plate 37 is used to fix the seal clamp assembly, which is used to fix various seals. The seal clamp assembly is composed of a cylindrical main body 42, on which a fixed splint 43 is provided, and on which an inclined protrusion 44 is provided. The inclined protrusion 44 gradually increases in size from top to bottom. The cylindrical main body 42 is also provided with an opening press plate 45, and the release plate 45 is provided with a stepped thread 46. An extrusion ring is provided on the cylindrical main body 42, and an internal thread that cooperates with the stepped thread 46 can be provided inside the extrusion ring. The extrusion ring continuously descends on the stepped thread 46 by rotating, thereby cooperating with the inclined protrusion 44. The continuous decline of the extrusion ring means that the contact surface with the inclined protrusion 44 increases. Since the inclined protrusion gradually increases as it protrudes downward, when the extrusion ring continuously descends, the inclined protrusion will cause the fixed splint 43 to continuously shrink, thereby fixing seals of different sizes in the cylindrical main body 42.

[0049] The opening button 45 can be contracted by squeezing, so that the stepped thread on the opening button 45 is out of contact with the internal thread in the squeezing ring. At this time, the squeezing ring can be pushed upward to return to the initial position where it is not in contact with the inclined protrusion 44. In other embodiments, the squeezing ring can be moved upward to return to the initial position where it is not in contact with the inclined protrusion 44 by reversing the squeezing ring.

[0050] A door 46 is provided at the lower side of the cylindrical body 42 , and a door rotating bracket 47 is provided at one side of the door 46 . The door rotating bracket 47 is fixed at a protruding position of the lower shell 12 protruding from the upper shell 11 . The protruding portion of the lower shell 12 is used to accommodate the swinging of the door 46 .

[0051] The door 46 is rotatably mounted on the door rotating bracket 47 . The door 46 and the door rotating bracket 47 are rotatably connected at a connecting hole 48 . The rotatable connection can be achieved by snapping or connecting with a rotating shaft.

[0052] A matching cylinder 50 is provided on the lower side of the cylindrical main body 42, and a matching groove 49 is provided on the door 46. The matching groove 49 is matched with the matching cylinder 50, and the semi-cylindrical structure of the matching cylinder 50 extends into the matching groove 49, so that when the cylindrical main body 42 carrying the seal descends, the matching cylinder 50 follows the decline, and when the matching cylinder 50 descends, half of the matching cylinder 50 located in the matching groove 49 will contact the bottom end surface of the matching groove 49 and apply a force to the outermost side of the lower end wall of the matching groove 49, thereby pushing the door 46 as a whole to rotate downward around the connection 48, thereby realizing the opening of the door 46.

[0053] When the cylindrical body 42 moves upward, the mating cylinder 50 moves to the opening of the mating groove 49 with the opening facing downward. At this time, the mating cylinder 50 will exert an upward force on the outermost side of the upper end wall of the mating groove 49, thereby pushing the door 46 as a whole to rotate upward around the connection 48, thereby achieving the closing of the door 46.

[0054] The above technical solution has multiple locking and unlocking modes:

[0055] Two control buttons are arranged on the top of the upper housing 11 . When in use, the electromagnetic lock 22 and the steering gear 26 are controlled by the two buttons respectively. The control button of the steering gear 26 needs to be able to control to achieve different rotation degrees of the steering gear 26 .

[0056] In normal use, the spring upper fixing plate 18 is fixed to the top of the upper housing 11 by connecting screws;

[0057] The support frame 19 and the connecting block 21 and the support plate 35 are fixedly connected in sequence, the clamp support plate 37 is fixedly connected to the cylindrical body 42, the door rotating bracket 47 is fixed at the position where the lower end shell 12 protrudes from the upper end shell 11, and the door 46 is rotatably installed on the door rotating bracket 47. The above fixing method is preferably a bolt connection.

[0058] The components on the support frame 19 and the connecting block 21 constitute an upper and lower stamping assembly, which drives the fixed stamp fixture assembly to move up and down under the action of the pushing ring 14, thereby realizing the stamping action.

[0059] When in use, firstly, the electromagnetic lock 22 is unlocked by pressing the button. After the electromagnetic lock 22 is unlocked, the ejector pin 24 is disengaged from the lock hole of the seal buckle. At this time, the upper and lower stamping assemblies can move up and down. Similarly, when the electromagnetic lock 22 is locked, the ejector pin 24 is inserted into the lock hole of the seal buckle. At this time, the upper and lower stamping assemblies cannot move.

[0060] The steering gear 26 is controlled to rotate by a button, and the steering gear 26 drives the gear 18 to rotate, thereby driving the tongue lock 27 to slide to both sides. The tongue lock 27 slides to extend the connecting pin 28, and the connecting pin 28 extends and is inserted into the insertion hole 17 of the matching plate 16, thereby completing the cooperation between the push ring 14 and the connecting pin 28, thereby achieving the movement of the upper and lower stamp assemblies by pushing the push ring 14. Similarly, flipping the steering gear 26 can disengage the push ring 14 from the upper and lower stamp assemblies, thereby achieving free movement of the upper and lower stamp assemblies.

[0061] Further rotation of the servo 26 can cause the lock rocker arm 32 to drive the lock rocker arm block 33 to rotate. The lock rocker arm block 33 rotates to contact the buckle plate boss 34, and further drives the buckle plate 29 to slide by pushing the buckle plate boss 34. At this time, the buckle plate 29 is separated from the buckle 38, and the buckle plate 29 no longer hinders the buckle 38 from descending. At this time, the buckle 38 can freely separate from the buckle plate 29. At this time, the clamp support plate 37 can be separated from the upper and lower stamp assemblies, so that the fixed seal clamp assembly can slide out from the external housing 10 to facilitate the replacement of the seal from the fixed seal clamp assembly.

[0062] When the seal clamp assembly needs to be re-engaged with the upper and lower seal assemblies, it is only necessary to fix the seal clamp assembly to the clamp support plate 37 and then push the clamp support plate 37 into the upper side of the external housing 10. Since the upper side of the buckle 38 is a trapezoid or a triangle and has an inclined surface, the buckle 38 can be directly inserted into the fastener hole 30. Under the action of the spring 36, the buckle plate 29 will clamp the buckle 38 again, thereby reconnecting the furniture support plate 37 with the upper and lower seal assemblies.

[0063] At the same time, when stamping, if the stamping action time times out, the offline machine 26 can still be started, and the servo 26 drives the gear 18 to rotate, thereby driving the tongue lock 27 to slide inward. The tongue lock 27 slides inwardly, causing the connecting ejector pin 28 to slide out of the insertion hole 17 of the matching plate 16, so that the fixed stamp clamp assembly is re-assembled with the upper and lower stamp assemblies and rises under the pull of the tension spring 41, so that the seal buckle 23 rises to the position where the seal buckle lock hole is aligned with the ejector pin 24. After the electromagnetic lock 22 is opened and locked, the ejector pin 24 is inserted into the seal buckle lock hole. At this time, the upper and lower stamp assemblies cannot move.

[0064] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
