[0021] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the present invention, the specific implementation method, structure, characteristics and effects of the model connection platform assembly proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0022] On the one hand, if Figure 1-3 As shown, the embodiment of the utility model provides a model connection platform assembly for a laminate manufacturing device, the laminate manufacturing device includes a main structure, and the model connection platform assembly includes:

[0023] A connecting frame unit, the connecting frame unit includes a frame body 160, the frame body 160 is used to be directly or indirectly connected to the main structure, and the connecting frame unit also includes a first fixing hanger 110 and a second fixing hanger 120 fixedly connected to the frame body 160;

[0024] The model connection platform 200 includes at least one first movable hanging member 210, at least one second movable hanging member 220 and an elastic plate 230. The first movable hanging member 210 and the second movable hanging member 220 are arranged on the elastic plate 230 at intervals. The first movable hanging member 210 is used to be hung with the first fixed hanging member 110, and the second movable hanging member 220 is used to be hung with the second fixed hanging member 120.

[0025] The height between the second fixed hanging part 120 and the elastic plate 230 is higher than the height between the first movable hanging part 210 and the elastic plate 230 .

[0026] Among them, the frame 160 is used to detachably connect and fix the elastic plate 230, and the frame 160 is also used to be directly or indirectly connected to the equipment body. Specifically, the frame 160 can be directly or indirectly connected to the lifting mechanism of the three-dimensional forming equipment through a bolt handle or other structure, so that the frame can be lifted and moved.

[0027] The elastic plate 230 is a plate-like structure, which has the characteristics of high hardness and good elasticity. The elastic plate 230 can be bent in any direction under the action of external force, and return to flatness after the external force is removed. For example, the elastic plate 230 can be a spring steel plate.

[0028] The number of the first fixed hanger 110 and the second fixed hanger 120 can be one or more respectively, and the number of the first fixed hanger 110 and the second fixed hanger 120 can be the same or different. The number of the first movable hanger 210 and the second movable hanger 220 can be one or more respectively, and the number of the first movable hanger 210 and the second movable hanger 220 can be the same or different. The first fixed hanger 110 and the first movable hanger 210 can correspond one to one, or the first fixed hanger 110 can be used to hang multiple first movable hangers 210. Similarly, the second fixed hanger 120 and the second movable hanger 220 can correspond one to one, or the second fixed hanger 120 can be used to hang multiple second movable hangers 220. It can be understood that a third fixed hanger, etc., can also be included, and a third movable hanger, etc. can also be included.

[0029] The structures of the first fixed hanger 110 and the second fixed hanger 120 can be various, so as to be able to cooperate with the first movable hanger 210 and the second movable hanger 220 for hanging respectively. For example, the first fixed hanger 110 and the second fixed hanger 120 are both hanging bars, or the first fixed hanger 110 and the second fixed hanger 120 are both connecting parts with hanging holes, and the first movable hanger 210 and the second movable hanger 220 are both hooks that can be hung on the hanging bar or the hanging hole. Alternatively, the first movable hanger 210 and the second movable hanger 220 can be both hanging bars or connecting parts with hanging holes, and the first fixed hanger 110 and the second fixed hanger 120 can be hooks that can be hung on the hanging bar or the socket. Among them, the hanging bar can be cylindrical, and its cross-section can be rectangular.

[0030] The height of the second fixed hanger 120 from the elastic plate 230 is higher than the height of the first movable hanger 210 from the elastic plate 230. Specifically, the height of the contact surface between the second fixed hanger 120 and the second movable hanger 220 from the elastic plate 230 is higher than the height of the contact surface between the first fixed hanger 110 and the first movable hanger 210 from the elastic plate 230. The height of the contact surface between the second fixed hanger 120 and the second movable hanger 220 from the elastic plate 230 refers to the vertical distance between the contact surface between the second fixed hanger 120 and the second movable hanger 220 and the elastic plate 230 when the second movable hanger 220 is hung with the second fixed hanger 120 and is limited perpendicular to the elastic plate 230. If the second fixed hanger 120 is a hanging bar, it refers to the vertical distance between the top surface of the hanging bar and the top surface of the elastic plate 230. The height of the contact surface between the first fixed hanger 110 and the first movable hanger 210 from the elastic plate 230 refers to the vertical distance between the contact surface between the first fixed hanger 110 and the first movable hanger 210 and the elastic plate 230 when the first fixed hanger 110 and the first movable hanger 210 are limited perpendicular to the elastic plate 230. If the first movable hanger 210 is a hook, it refers to the vertical distance between the bottom surface of the hook and the top surface of the elastic plate 230. Then, when the model connection platform 200 is moved, the second fixed hanger 120 can make way for the first movable hanger 210 by the height difference with the first movable hanger 210. At the same time, the height of the first fixed hanger 110 is adapted to the height of the first movable hanger 210, and the height of the second fixed hanger 120 is adapted to the height of the second movable hanger 220, so that after the single-direction horizontal movement model connection platform 200 is in place, the first movable hanger 210 and the second movable hanger 220 are respectively hung on the first fixed hanger 110 and the second fixed hanger 120.

[0031] It is worth noting that, in order to realize that the model connection platform 200 is moved only in a single direction for hanging, the hanging direction of the first movable hanger 210 and the second movable hanger 220 is the same, and the hanging direction refers to the moving direction of the model connection platform 200 for hanging, or when the first movable hanger 210 and the second movable hanger 220 are hooks, the hooks are inserted into the hanging strips through the hanging openings to realize hanging, and the hanging direction is the direction of the hanging openings. In the hanging direction, the first movable hanger 210 is located in front of the hanging direction of the second movable hanger 220, that is, when the model connection platform 200 is moved, the first movable hanger 210 first passes under the second fixed hanger 120, and then continues to move forward, and then the first movable hanger 210 is hung on the first fixed hanger 110, and the second movable hanger 220 is hung on the second fixed hanger 120, so as to make way through the height difference.

[0032] The utility model proposes a model connection platform assembly and laminate manufacturing equipment, which mainly disassembles and assembles the elastic plate by hanging the movable hanger and the fixed hanger, thereby ensuring the connection strength of the elastic plate and making the disassembly process more convenient. At the same time, the height difference between the first movable hanger and the second fixed hanger is such that the second fixed hanger is higher, so that the second fixed hanger makes way for the movement of the first movable hanger. The hanging can be achieved by simply pushing the model connection platform in the hanging direction, avoiding the need to move the spring steel plate in two or more directions to complete the hanging, and realizing the hanging of the model connection platform in a single direction, making the fixation of the model connection platform more convenient. It can be understood that if the user first moves the model connection platform 200 to a certain position in the vertical direction, and then moves the model connection platform 200 in the hanging direction, the assembly of the model connection platform 200 can also be completed.

[0033] In one embodiment, a guide groove 101 is provided on the frame body 160, which faces the elastic plate 230. The guide groove 101 passes through both sides of the connecting frame unit, and respectively forms a first hanging and giving way opening 102 and a second hanging and giving way opening 103. The first fixed hanger 110 is opposite to the first hanging and giving way opening 102, and the second fixed hanger 120 is opposite to the second hanging and giving way opening 103. The model connection platform 200 also includes at least one guide plate 240, which is connected to the elastic plate 230, and the first movable hanger 210 and the second movable hanger 220 are arranged on the guide plate 240. The guide plate 240 is used to be inserted into the guide groove 101 from one side of the second hanging and giving way opening 103, and the first movable hanger 210 is used to be hung with the first fixed hanger 110 through the first hanging and giving way opening 102, and the second movable hanger 220 is used to be hung with the second fixed hanger 120 through the second hanging and giving way opening 103.

[0034] The number of guide grooves 101 and guide plates 240 can be multiple, such as six, and the guide grooves 101 and guide plates 240 correspond one to one. The interaction between the guide grooves 101 and the guide plates 240, on the one hand, plays a guiding role when the model connection platform 200 is moved and hung, avoiding the position deviation of the model connection platform 200 that causes the model connection platform 200 to be unable to be hung accurately. On the other hand, it plays a limiting role on the guide plate 240, making the position of the elastic plate 230 more stable. In addition, the guide plate 240 also plays a role in reinforcing the elastic plate 230 and facilitating the processing of the first movable hanging part 210 and the second movable hanging part 220. For example, in the embodiment where the first movable hanging part 210 and the second movable hanging part 220 are hooks, by cutting on the guide plate 240 of the plate structure and processing the notch, hooks of different heights can be formed, such as forming a second movable hanging part 220 with a higher position and a first movable hanging part 210 with a lower position. The increase in the number of guide plates 240 can also prevent or reduce the deformation of the elastic plate 230 in the model direction.

[0035] Furthermore, the first side of the elastic plate 230 is used to connect the model, and the first movable hanging part 210 and the second movable hanging part 220 are arranged on the second side of the elastic plate 230 opposite to the first side, or the guide plate 240 is arranged on the second side of the elastic plate 230 opposite to the first side. The surface of the first side of the elastic plate 230 is a smooth surface or a rough surface, which can be determined according to the actual printing situation. If the model is large in volume and heavy in weight, a surface with higher adhesion strength can be selected. If the model has a large adhesion area and is light in weight, a surface with lower adhesion strength can be selected. The rough surface can be processed by laser engraving, that is, the rough surface is a laser engraving processing surface.

[0036] In one embodiment, the width of the guide groove 101 decreases in the direction from the second hooking and yielding opening 103 to the first hooking and yielding opening 102, which can facilitate the insertion and alignment of the guide plate 240 and ensure the limiting effect on the guide plate 240. In a more specific embodiment, the width of the guide groove 101 at the second hooking and yielding opening 103 is greater than the thickness of the guide plate 240, which facilitates the alignment of the guide plate 240.

[0037] The connecting frame unit also includes a flexible member, which is arranged on at least one side wall of the guide groove 101 and near the first hooking and yielding opening 102, and is used to squeeze the guide plate 240. The flexible member can extend to the first hooking and yielding opening 102, and the flexible member can be arranged on a single side wall of the guide groove 101, and the distance between the flexible member and the side wall on the opposite side of the guide groove 101 is less than the thickness of the guide plate 240, or the flexible member is arranged on the opposite side walls of the guide groove 101, and the distance between the opposite flexible members is less than the thickness of the guide plate 240. In the process of the guide plate 240 moving toward the first hooking and yielding opening 102, the flexible member will be squeezed due to the width limitation, and then provide the user with a sense of damping when pushing, prompting the user that the push is about to be in place, and at the same time, it can also ensure better limiting of the guide plate 240. The distance between the flexible member and the side wall of the guide groove 101 on the opposite side, or the distance between the opposite flexible members, is 0.1 mm to 1 mm smaller than the thickness of the guide plate 240 , in order to provide a damping feeling while avoiding excessive resistance to the guide plate 240 that causes difficulty in pushing.

[0038] In one embodiment, if Figure 3 As shown, the connecting frame unit further includes a slot plate 140, and the frame body 160 includes a bottom opening and an inner cavity 161 connected to the bottom opening, and the slot plate 140 is located in the inner cavity 161. The guide groove 101 is opened on the slot plate 140, which can reduce the weight of the frame body 160.

[0039] In one embodiment, a drain port 162 is further provided on the frame 160 . The drain port 162 is connected to the inner cavity 161 and the outside of the frame 160 , and is used to discharge the resin entering the inner cavity 161 in time.

[0040] In one embodiment, at least one drainage hole is provided on the elastic plate 230, which cooperates with the drainage port 162 to allow the resin entering the inner cavity 161 to be discharged faster, and can reduce the connection strength between the model and the elastic plate 230, making the model easier to demold.

[0041] In one embodiment, a first mounting groove 151 and a second mounting groove 152 are respectively formed on two sides of the frame 160 , the first fixing hanger 110 is at least partially embedded in the first mounting groove 151 , and the second fixing hanger 120 is at least partially embedded in the second mounting groove 152 .

[0042] The embedding may be partial embedding, and the first installation groove 151 and the second installation groove 152 are used to make the height of the first fixing hanger 110 and the second fixing hanger 120 more stable and reduce installation errors. The embedding may also be full embedding, and the outer surfaces of the first fixing hanger 110 and the second fixing hanger 120 are located in the same plane as the two side walls of the frame 160, and the outer surface of the frame 160 is neater.

[0043] In order to make the position of the model connection platform 200 relative to the frame 160 more stable, in one embodiment, the connection frame unit further includes a pressurizing component 170, which is movably connected to the frame 160. The position of the pressurizing component 170 includes a pressurizing position and a disengaging position. In the pressurizing position, the pressurizing component 170 is directly or indirectly in contact with the elastic plate 230. In the disengaging position, at least part of the pressurizing component 170 is separated from the elastic plate 230. The pressurizing component 170 is used to move between the pressurizing position and the disengaging position under the action of an external force.

[0044] In the embodiment where the guide plate 240 is disposed on the elastic plate 230, the pressurizing assembly 170 abuts against the guide plate 240 when in the pressurizing position. The pressurizing assembly 170 abuts against the guide plate 240 to apply a downward external force to the elastic plate 230 through the guide plate 240, while the first fixed hanger 110 and the second fixed hanger 120 indirectly apply an upward external force to the elastic plate 230 through the first movable hanger 210 and the second movable hanger 220 respectively, thereby causing the elastic plate 230 to be subjected to an opposite balancing force, so that the position of the elastic plate 230 is stable and not easy to move.

[0045] In order to make the external force of the pressure component 170 squeezing the elastic plate 230 more uniform, in one embodiment, the pressure component 170 and the elastic plate 230 are respectively located on opposite sides of the frame 160, and a through hole 163 is opened on the frame 160. The pressure component 170 is at least partially movably connected to the through hole 163, and acts on the guide plate 240 through the through hole 163.

[0046] In another embodiment, the frame 160 is provided with an active cavity and a clearance opening 164, the pressurizing assembly 170 is located in the active cavity, the frame 160 is provided with a through hole 163, the pressurizing assembly 170 is at least partially movably connected to the through hole 163, acts on the guide plate 240 through the through hole 163, the clearance opening 164 is connected to the active cavity, the pressurizing assembly 170 is connected to the outside through the clearance opening 164, and the position of the pressurizing assembly 170 can be adjusted through the clearance opening 164. The active cavity can protect and limit the pressurizing assembly 170.

[0047] In a more specific embodiment, the pressurizing assembly 170 includes a movable plate 171 and at least one pressing head 172, the pressing head 172 is connected to the movable plate 171, and extends toward the elastic plate 230. The through hole 163 corresponds to the pressing head 172, the pressing head 172 is movably connected to the through hole 163, and the pressing head 172 is used to directly or indirectly press the elastic plate 230, such as the pressing head 172 is used to press the guide plate 240.

[0048] The number of the pressing heads 172 may be multiple. For example, in the embodiment in which the number of the guide grooves 101 and the number of the guide plates 240 are both six, the number of the pressing heads 172 may be twelve, and each guide plate 240 corresponds to two pressing heads 172. The two pressing heads 172 corresponding to the same guide plate 240 are arranged at intervals in the extending direction of the guide plate 240. In the embodiment in which the connecting frame unit includes the slot plate 140 and the guide groove 101 is opened in the slot plate 140, the slot plate 140 is provided with a clearance opening, which corresponds to the through hole 163 and is used to make way for the pressing heads 172.

[0049] In one embodiment, if Figure 6 As shown, the connecting frame unit further includes a sealing member 190, which is disposed in the through hole 163, and the pressing head 172 is connected to the sealing member 190 and abuts against or presses the sealing member 190. The sealing member 190 and the through hole 163 are interference fit.

[0050] A connecting boss may be provided on the inner wall of the through hole 163, and the seal 190 is connected to the through hole 163 by interference fit, and is limited by the connecting boss. The seal 190 is used to seal the gap between the pressure head 172 and the through hole 163, and the seal 190 is in sliding contact with the pressure head 172 and is fixedly connected to the through hole 163. The seal 190 can prevent the resin from flowing to the top of the frame 160 through the gap between the pressure head 172 and the through hole 163, and prevent it from being difficult to clean. In the embodiment in which the frame 160 is provided with an active cavity, the seal 190 is used to prevent the resin from entering the active cavity, and then protect the components in the active cavity, avoid resin residue, and avoid cleaning in the active cavity.

[0051] In the embodiment in which the frame 160 is provided with an active cavity, the frame 160 may further include a bottom frame 165 and a top frame 166, at least one of which is provided with an active groove 167, and the bottom frame 165 or the top frame 166 covers the active groove 167 to enclose the active cavity. Figure 6 As shown, a movable groove 167 is opened on the bottom frame 165, and the top frame 166 includes a plate-like structure, which covers the notch of the movable groove 167 to enclose a movable cavity.

[0052] The position of the pressurizing assembly 170 can be adjusted in a variety of ways. For example, in one embodiment, the connecting frame unit further includes a switching assembly 180, which is respectively connected to the frame 160 and the pressurizing assembly 170. The switching assembly 180 is used to move under the action of an external force to drive the pressurizing assembly 170 to move relative to the frame 160.

[0053] The switching assembly 180 and the pressurizing assembly 170 may be connected in abutment. Take the aforementioned pressurizing assembly 170 including a movable plate 171 and at least one pressure head 172, and the frame 160 is provided with an active cavity and a clearance opening 164 as an example. The movable plate 171 is located in the active cavity, and the switching assembly 180 interacts with the movable plate 171 through the clearance opening 164, such as abutment. By moving the switching assembly 180, the movable plate 171 can be moved and limited, thereby realizing the position switching of the pressurizing assembly 170 between the pressurizing position and the disengaged position.

[0054] In one embodiment, if Figure 2 , Figure 7-8 As shown, the switching assembly 180 includes a rotating wheel 181 and a handle 182, the handle 182 is rotatably connected to the frame 160, the rotating wheel 181 is connected to the handle 182, and the rotating wheel 181 includes a raised area and a non-raised area. The handle 182 is used to drive the rotating wheel 181 to rotate under the action of an external force, so that the raised area of ​​the rotating wheel 181 abuts against the pressurizing assembly 170, and the pressurizing assembly 170 is located in the pressurizing position, or the non-raised area of ​​the rotating wheel 181 abuts against the pressurizing assembly 170, and the pressurizing assembly 170 is located in the disengaged position.

[0055] The rotating wheel 181 may be a cam. The handle 182 is used to rotate in a preset direction under the action of an external force, so that the rotating wheel 181 gradually moves from the non-raised area abutting against the movable plate 171 to the raised area abutting against the movable plate 171. During this process, the rotating wheel 181 will push the movable plate 171 and the pressure head 172 to move closer to the guide plate 240 until the raised area abuts against the movable plate 171. Figure 7As shown, the pressing head 172 will press the guide plate 240 to achieve the positioning of the guide plate 240 and the elastic plate 230. The handle 182 is used to rotate in the reverse direction of the preset direction under the action of external force, so that the rotating wheel 181 gradually moves from the raised area to the movable plate 171 to the non-raised area to the movable plate 171. During this process, the position of the end of the rotating wheel 181 opposite to the movable plate 171 moves upward, allowing the movable plate 171 and the pressing head 172 to move away from the guide plate 240. Figure 8 As shown, the guide plate 240 is then released, so that the guide plate 240 and the elastic plate 230 can be detached.

[0056] In one embodiment, if Figure 6 As shown, the connecting frame unit further includes a second elastic member 130, which is located between the frame body 160 and the pressurizing assembly 170. The second elastic member 130 is used to apply an elastic force to the pressurizing assembly 170 to move away from the elastic plate 230. The second elastic member 130 is used to make the pressurizing assembly 170 always abut against the rotating wheel 181. When the rotating wheel 181 rotates to the non-convex area to abut against the movable plate 171, the movable plate 171 and the pressure head 172 can move upward to a position away from the guide plate 240. In some other embodiments, the second elastic member 130 may also be absent. When the rotating wheel 181 rotates to the non-convex area to face the movable plate 171, the movable plate 171 will be in a state of contacting and abutting with the guide plate 240 due to gravity, but it is not in a state of extrusion. Therefore, the model connecting platform 200 can still be disassembled. In addition, the second elastic member 130 is located in the active cavity, and the active cavity plays a role in protecting the second elastic member 130.

[0057] In one embodiment, if Figure 1 As shown, the switching assembly 180 further includes a handle limiter 183 , which is connected to the frame 160 . The handle limiter 183 is used to interact with the handle 182 to limit the rotation direction of the handle 182 .

[0058] Due to the limitation of the cam structure, or in some embodiments, due to the limitation of the handle 182 structure, the handle 182 can only switch between the raised area and the non-raised area abutting against the movable plate 171 when the handle 182 rotates in a specific area. By providing the handle limiter 183, the rotation position of the handle is limited, so that it is easy to rotate in the correct direction.

[0059] In one embodiment, the pressurizing assembly 170 includes a movable plate 171, a pressing plate 173, and a first elastic member 174, wherein the first elastic member 174 is connected between the movable plate 171 and the pressing plate 173, and the rotating wheel 181 abuts against the pressing plate 173. The first elastic member 174 applies an elastic force that moves the movable plate 171 and the pressing plate 173 away from each other, and the elastic force is greater than a preset threshold. It is understood that the aforementioned pressure head 172 may be provided on the movable plate 171.

[0060] The first elastic member 174 can be a spring with a relatively large elastic force. When the first elastic member 174 satisfies the instantaneous action of the pressure plate 173, the first elastic member 174 can be approximately used as a rigid member. Then, when the handle 182 rotates in a preset direction, the pressure plate 173, the first elastic member 174 and the movable plate 171 can be regarded as an integrated structure, and the whole moves downward under the action of the rotating wheel 181. In an ideal state, when the handle 182 rotates until the raised area of ​​the rotating wheel 181 abuts against the movable plate 171, the pressure head 172 appropriately squeezes the guide plate 240. However, due to assembly errors and processing errors, the pressure head 172 may over-exert the guide plate 240, which will cause the guide plate 240 to move downward, resulting in the flatness of the elastic plate 230 being affected. The first elastic member 174 is used to release the excessive extrusion caused by the error. Before the handle 182 rotates to the point where the raised area abuts the movable plate 171, if the pressure head 172 has squeezed the guide plate 240, the guide plate 240 will apply a reverse upward force to the pressure head 172 or the movable plate 171. When the handle 182 continues to rotate, the raised area gradually squeezes the movable plate 171, and the first elastic member 174 will shrink due to the opposite external force, thereby preventing the pressure head 172 from further rigidly squeezing the guide plate 240, and avoiding the problem of the elastic plate 230 being uneven due to the guide plate 240 being rigidly pushed downward.

[0061] In one embodiment, if Figure 5 As shown, the pressurizing assembly 170 further includes a guide block 175, which is connected to the movable plate 171 and movably connected to the clearance opening 164. The guide block 175 is provided with a guide groove 1751, and the first elastic member 174 and the pressing plate 173 are both located in the guide groove 1751. The pressurizing assembly 170 further includes at least one guide rod 176, and the pressing plate 173 is provided with a guide hole 1731 corresponding to the guide rod 176. The guide rod 176 is at least partially located in the guide groove 1751. The guide rod 176 is connected to the guide block 175 and movably connected to the guide hole 1731.

[0062] The guide groove 1751 is used to protect the first elastic member 174 to prevent the first elastic member 174 from leaking adhesive resin and affecting the expansion and contraction. On the other hand, it plays a guiding role in the movement of the pressing plate 173. Furthermore, the guide rod 176 and the inner wall of the guide groove 1751 jointly limit the movement direction of the pressing plate 173, so that the movement of the pressing plate 173 is stable.

[0063] In one embodiment, if Figure 4 As shown, the model connection platform 200 further includes two force-applying handles 250 , which are respectively connected to opposite sides of the elastic plate 230 . The force-applying handles 250 extend perpendicularly to the elastic plate 230 , and are used to slide against the frame 160 .

[0064] The force-applying handle 250 may be a U-shaped handle, which is arranged in a direction perpendicular to the elastic plate 230, so as to facilitate lifting and moving the elastic plate 230, and to apply external force to bend and demould the elastic plate 230. The distance between the two force-applying handles 250 may match the length of the frame 160, and when the model connecting platform 200 is connected to the connecting frame unit, the force-applying handles 250 and the side walls of the frame 160 may play a guiding role in the movement of the model connecting platform 200.

[0065] In one embodiment, the model connecting platform 200 further includes at least one rolling member 260 , which is rotatably connected to the force applying handle 250 , and the rolling member 260 is used to roll on the surface of the frame 160 opposite to the elastic plate 230 .

[0066] One or more rolling members 260 may be connected to the force application handle 250, and the vertical distance between the rolling member 260 and the elastic plate 230 is consistent with the height of the frame 160, or slightly higher than the height of the frame 160, such as 1 mm, 5 mm, etc. When the rolling member 260 is connected to the top surface of the frame 160 by rolling, the height of the first movable hanging member 210 and the second movable hanging member 220 is sufficient to be hung on the first fixed hanging member 110 and the second fixed hanging member 120, and then the height of the second fixed hanging member 120 is higher than the first movable hanging member 210. When installing the model connection platform 200, it is only necessary to place the rolling member 260 on the top surface of the frame 160, and then push the model connection platform 200 to complete the hanging of the model connection platform 200, making the installation convenient.

[0067] In one embodiment, the model connecting platform 200 also includes an angle limiting member 270, which includes a first connecting surface and a second connecting surface, the angle between the first connecting surface and the second connecting surface is 90 degrees, the first positioning surface is connected to the elastic plate 230 surface, and the second positioning surface is connected to the force handle 250 surface.

[0068] The angle limiting member 270 is used to limit the relative angle between the force applying handle 250 and the elastic plate 230, enhance the structural strength of the model connection platform 200, and facilitate the positioning and connection of the force applying handle 250 and the elastic plate 230. The angle limiting member 270 can be a thin steel bar, and can be fixed to the force applying handle 250 and the elastic plate 230 by welding, bonding, or integral molding.
