Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of simulation walking platforms, in particular to a simulation walking platform for virtual shooting. BACKGROUND

[0002] Virtual shooting technology is booming in the field of film and television production, which realizes better integration of actors and virtual scenes by presenting backgrounds on LED screens through 3D modeling and other means, greatly saving the cost of setting and post-production time. In the process of virtual shooting, actors often need to simulate various walking and other actions on a specific platform to meet the shooting needs of virtual scenes. However, the platform does not provide cold and hot air functions in the prior art, resulting in low comfort of actors during shooting.

[0003] The patent with publication number CN219630592U discloses a VR universal treadmill with good comfort, which sets a blowing assembly on one side of the waistband. In summer, the fan can guide air out of the air inlet on the installation box and blow it onto the user's body to blow and dissipate heat. In winter, the heating pipe is powered to heat up. When the fan guides air out of the air inlet, the air becomes hot air after passing through the heating pipe, and then blows onto the user's body, greatly improving comfort and being more practical.

[0004] Although the above scheme blows air with appropriate temperature to the actor according to the actual temperature, the fan can only blow air to the actor from one side of the actor. If the actor's posture does not change, the airflow or high-temperature airflow will continue to blow on the same part of the actor's body, causing the local temperature of the actor's body to be too low or too high, resulting in uneven heat dissipation or heating of the actor's body, and also causing discomfort. SUMMARY

The air duct has an air inlet and an air outlet, with the air outlet facing upward and extending through the mounting slot to the top of the panel. The width of the air outlet is smaller than the width of the mounting slot. The middle of the rotating shaft is fixedly connected to the air duct, and both ends of the rotating shaft are rotatably connected to the panel. The blower is disposed at the air inlet and is used to blow air into the air duct. The multiple heating mechanisms are respectively disposed within the air ducts of the multiple blower components.

[0007] Preferably, the blower mechanism further includes an angle adjustment structure, which includes a limiting plate, a crossbeam, and a telescopic rod; the limiting plate is vertically disposed on one side of the air duct; both ends of the crossbeam are fixedly connected to both ends of the rotating shaft; the telescopic rod is movably disposed in the middle of the crossbeam, and one end of the telescopic rod abuts against the limiting plate.

[0008] Preferably, the blower mechanism further includes two self-lifting structures located at both ends of the rotating shaft. Each self-lifting structure includes a frame, a connecting seat, and a guide spring assembly. The frame is fixedly connected to the panel. The connecting seat is located inside the frame and is rotatably connected to the rotating shaft. The guide spring assembly is used to control the movement direction of the connecting seat.

[0009] Preferably, the guide rebound assembly includes at least a second guide rod, with two second guide rods respectively disposed on both sides of the connecting seat. The second guide rods are fixedly connected to the frame, and the connecting seat is slidably connected to the second guide rods. A first spring is sleeved on the second guide rod, with both ends of the first spring abutting against the lower surfaces of the frame and the connecting seat, respectively.

[0010] Preferably, the angle adjustment structure further includes a rolling assembly, which is disposed at the end of the telescopic rod that contacts the limiting plate. The rolling assembly is used to reduce the friction between the telescopic rod and the limiting plate.

[0011] Preferably, the blower mechanism further includes an air outlet self-opening component disposed at the air outlet, the air outlet self-opening component including a rectangular frame and multiple opening and closing blades; the inner cavity of the rectangular frame is connected to the air outlet; the multiple opening and closing blades are disposed at equal intervals in the inner cavity of the rectangular frame, and the middle part of the opening and closing blades is rotatably connected to the rectangular frame.

[0012] Preferably, the opening and closing blade has a first leaf surface and a second leaf surface, the first leaf surface of the opening and closing blade covers the second leaf surface of the adjacent opening and closing blade, and a window is provided on the second leaf surface.

[0013] Preferably, the heating mechanism comprises a fixed plate, two heating plates and an opening structure; the fixed plate is fixedly connected with the rotating shaft; the two heating plates are rotationally connected with the fixed plate; and the opening structure is used for controlling the included angle between the two heating plates.

[0015] Preferably, the opening structure further comprises a synchronous assembly arranged between the two transmission assemblies and connected with the two transmission assemblies.

[0016] The present application has the following beneficial effects compared with the prior art:

[0017] 1. The present application is provided with a panel, a plurality of blowing mechanisms and a plurality of heating mechanisms. When the ambient temperature is high, the plurality of blowing mechanisms operate in coordination, the air blown by the blower flows rapidly along the air duct pipe, and the rotating shaft can drive the air duct pipe to rotate to change the angle of the air outlet of the air duct pipe, ensuring uniform heat dissipation of the actor's body. When the ambient temperature is low, the heating mechanism and the blowing mechanism are started synchronously to make the air temperature around the actor uniform, and the body parts are evenly heated, effectively solving the problem of local cooling or heating of the actor's body, thereby ensuring that the actor obtains a comfortable experience in the virtual shooting process.

[0018] 2. The present application is provided with an angle adjusting structure. When the angle of the air duct pipe needs to be adjusted, the length of the telescopic rod in the angle adjusting structure is elongated, and one end of the telescopic rod cannot move under the limitation of the limiting plate. Therefore, the other end of the telescopic rod moves under the reaction force of the limiting plate, the cross beam moves under the driving of the telescopic rod, and the air duct pipe moves under the driving of the rotating shaft, so that the air duct pipe rotates around the axis of the rotating shaft, changes the orientation of the air outlet, and changes the part of the actor's body on which the airflow blows. By changing the orientation of the air outlet of the air duct pipe through the angle adjusting structure, the airflow is prevented from continuously acting on the same part of the actor's body, and the uniformity and comfort of the blowing are effectively improved.

[0019] 3、The self-lifting structure is arranged, when the air duct pipe is subjected to downward pressure, and the downward force is greater than the upward force provided by the two guide rebound assemblies, the air duct pipe moves downward together with the rotating shaft and the connecting seat, under the control of the guide rebound assembly, the connecting seat moves downward stably, until the air outlet of the air duct pipe is flush with the panel, at this time, the air duct pipe stops moving, since the air outlet and the panel are in the same plane, the actor's foot feels a flat surface, and discomfort is not caused, the height of the air duct pipe is automatically adjusted through the self-lifting structure, so that the problem that the air outlet is higher than the panel and causes uncomfortable stepping is solved, and the air blowing effect and the actor's stepping experience are considered.

DETAILED DESCRIPTION

[0033] In order to further understand the features, technical means and specific purposes and functions achieved by the present application, the present application will be described in further detail below with reference to the drawings and specific embodiments.

[0034] Referring to Figures 1 to 12 , a simulation walking platform for virtual shooting includes a simulation walking platform body 1 and a blowing device arranged on the side of the simulation walking platform body 1, the blowing device including a panel 2, a plurality of blower 33 structures 3 and a plurality of heating mechanisms 4; the panel 2 is horizontally sleeved on the simulation walking platform body 1, and a plurality of mounting grooves 21 are evenly formed on the panel 2; the plurality of blower 33 structures 3 are arranged below the panel 2, and the plurality of blower 33 structures 3 are respectively arranged in the plurality of mounting grooves 21, the blower 33 structure 3 includes an air duct pipe 31, a rotating shaft 32 and a blower 33, the air duct pipe 31 has an air inlet and an air outlet, the air outlet faces upwards and extends above the panel 2 through the mounting groove 21, and the width of the air outlet is smaller than the width of the mounting groove 21, the middle part of the rotating shaft 32 is fixedly connected with the air duct pipe 31, the two ends of the rotating shaft 32 are rotationally connected with the panel 2, the blower 33 is arranged at the air inlet, and the blower 33 is used for blowing air into the air duct pipe 31; the plurality of heating mechanisms 4 are respectively arranged in the air duct pipes 31 in the plurality of blower 33 structures 3.

[0035] In actual work process, when the ambient temperature is high, the actor moves on the simulation walking platform body 1, which is easy to cause the body temperature to rise, at this time, multiple blowers 33 are started synchronously, the blower 33 starts to work, and the air is pushed to flow rapidly in the air duct pipe 31 to form a continuous airflow, the airflow is blown from the air outlet to the actor located in the middle. Since the actor is surrounded by multiple blowers 33, the body can be evenly contacted with the airflow, high-efficiency heat dissipation is realized, at the same time, the shaft 32 can drive the air duct pipe 31 to rotate, so that the airflow can be blown to different parts of the actor's body, avoiding the airflow continuously acting on the same position, and improving the comfort of heat dissipation. When the ambient temperature is low, the actor wears thin clothes and moves on the platform, which may cause the body temperature to drop. At this time, multiple heating mechanisms 4 and blowers 33 are started synchronously. The airflow blown by the blower 33 is heated by the heating mechanism 4 in the air duct pipe 31, and then blown to the actor from the air outlet. The cooperation of multiple heating mechanisms 4 and blowers 33 can keep the air around the actor at a uniform temperature, ensuring that the body is evenly heated. Through the cooperation of multiple blowers 33 and multiple heating mechanisms 4, whether the ambient temperature is high or low, the actor's body can be evenly heated and cooled during the change of body temperature, effectively solving the problem of uncomfortable feeling caused by local cooling or heating of the actor's body, thereby ensuring that the actor has a comfortable experience in the virtual shooting process.

[0036] Referring to Figure 4 and Figure 5 The blower 33 further includes an angle adjusting structure 34. The angle adjusting structure 34 includes a limiting plate 341, a cross beam 342, and an extension rod 343. The limiting plate 341 is vertically arranged on one side of the air duct pipe 31. The two ends of the cross beam 342 are fixedly connected with the two ends of the shaft 32. The extension rod 343 is movably arranged at the middle of the cross beam 342, and one end of the extension rod 343 abuts against the limiting plate.

[0037] If the air outlet of the air duct pipe 31 is fixed in direction, the airflow blown from the air outlet will continuously blow on the same part of the actor's body. Therefore, the angle adjusting structure 34 for adjusting the angle of the air outlet is arranged. In the initial state, the air outlet of the air duct pipe 31 is parallel to the limiting plate 341. When it is necessary to adjust the angle of the air duct pipe 31, the length of the extension rod 343 is elongated. One end of the extension rod 343 cannot move under the limitation of the limiting plate 341. Therefore, the other end of the extension rod 343 moves under the reaction force of the limiting plate 341. The cross beam 342 moves under the driving of the extension rod 343. The cross beam 342 drives the air duct pipe 31 to move through the shaft 32, so that the air duct pipe 31 rotates around the axis of the shaft 32. The direction of the air outlet is changed, so that the part of the actor's body blown by the airflow changes. The direction of the air outlet of the air duct pipe 31 is changed through the angle adjusting structure 34, so that the airflow continuously acts on the same part of the actor's body is avoided, and the uniformity and comfort of the blowing are effectively improved.

[0038] Referring to Figure 4 and Figure 6 As shown in the figure, the hair dryer 33 also includes two self-lifting structures 35 arranged at both ends of the rotating shaft 32, the self-lifting structure 35 includes a frame 351, a connecting seat 352 and a guide spring assembly 353; the frame 351 is fixedly connected with the panel 2; the connecting seat 352 is arranged inside the frame 351, and the connecting seat 352 is rotationally connected with the rotating shaft 32; the guide spring assembly 353 is used for controlling the moving direction of the connecting seat 352.

[0039] In the initial state, the two guide spring assemblies 353 exert an upward force on the rotating shaft 32, under the action of the force, the air duct pipe 31 is lifted upward, so that the air outlet of the air duct pipe 31 is stably kept at the upper end of the panel 2, therefore, when the angle of the air duct pipe 31 is adjusted, the airflow blown out of the air outlet can smoothly blow to the actor, avoiding the airflow blowing to the lower end of the panel 2 due to the low position of the air outlet, which affects the use effect, when the actor moves on the simulation walking platform body 1, if the actor steps on the air duct pipe 31, the air duct pipe 31 will be subjected to a downward pressure, when the downward force is greater than the upward force provided by the two guide spring assemblies 353, the air duct pipe 31 will move downward together with the rotating shaft 32 and the connecting seat 352, under the control of the guide spring assembly 353, the connecting seat 352 moves stably downward, until the air outlet of the air duct pipe 31 is flush with the panel 2, at this time, the air duct pipe 31 stops moving, since the air outlet is in the same plane with the panel 2, the actor's foot stepping on it will feel a flat surface, without discomfort, the height of the air duct pipe 31 is automatically adjusted by the self-lifting structure 35, thereby solving the problem of stepping discomfort caused by the air outlet being higher than the panel 2, and taking into account the airflow blowing effect and the actor's stepping experience.

[0040] Referring to Figure 6 and Figure 7 As shown in the figure, the guide spring assembly 353 includes at least a second guide rod 3531, the two second guide rods 3531 are arranged at both sides of the connecting seat 352 respectively, the second guide rod 3531 is fixedly connected with the frame 351, and the connecting seat 352 is slidingly connected with the second guide rod 3531, a first spring 3532 is sleeved on the second guide rod 3531, and both ends of the first spring 3532 abut against the lower surface of the connecting seat 352 and the frame 351 respectively.

[0041] In the initial state, the first spring 3532 on the second guide rod 3531 exerts an upward pushing force on the connecting seat 352, and the connecting seat 352 transmits the pushing force to the air duct pipe 31 through the rotating shaft 32, so that the air outlet of the air duct pipe 31 is stably kept at the upper end of the panel 2, and it is ensured that the air flow can normally blow to the actor. When the actor's foot contacts the air duct pipe 31, the air duct pipe 31 is subjected to a downward pressure, and the pressure is transmitted to the connecting seat 352 through the rotating shaft 32, so that a pressure difference is formed on the upper and lower sides of the connecting seat 352. At this time, the connecting seat 352 slides downward along the second guide rod 3531, the first spring 3532 is compressed and stores elastic potential energy, and the air duct pipe 31 also moves downward, until the air outlet is flush with the panel 2, to ensure the comfort of the actor when stepping on. When the actor's foot is separated from the air duct pipe 31, the downward force on the air duct pipe 31 disappears, the first spring 3532 releases the stored elastic potential energy, pushes the connecting seat 352 to move upward along the second guide rod 3531, and the connecting seat 352 drives the air duct pipe 31 to move upward through the rotating shaft 32, so that the air duct pipe 31 returns to the initial position, and the air outlet returns to the upper end of the panel 2, so as to work normally subsequently, thereby realizing automatic lifting and resetting of the air duct pipe 31.

[0042] With reference to Figure 5 and Figure 8 As shown in the figure: the angle adjusting structure 34 further comprises a rolling assembly 344, which is arranged at the end of the telescopic rod 343 in contact with the limiting plate 341, and is used for reducing the friction between the telescopic rod 343 and the limiting plate 341.

[0043] Specifically, the rolling assembly 344 comprises a connecting frame 3441, a roller 3442 and a first guide rod 3443, the middle part of the connecting frame 3441 is connected with the telescopic rod 343, both ends of the roller 3442 are connected with both ends of the connecting frame 3441, and the first guide rod 3443 is slidingly connected with the cross beam 342, and one end of the first guide rod 3443 is fixedly connected with the connecting frame 3441.

[0044] In the working process, when the rotating shaft 32 rises and falls with the air duct pipe 31, the cross beam 342 connected with the rotating shaft 32 and the telescopic rod 343 on the cross beam 342 will move synchronously. Since the end of the telescopic rod 343 is in contact with the limiting plate 341, if there is no rolling assembly 344, sliding friction will occur between the two, which will cause wear after a long time. After the rolling assembly 344 is arranged at the end of the telescopic rod 343, when the telescopic rod 343 rises and falls with the air duct pipe 31, it will drive the connecting frame 3441 to rise and fall together, and the connecting frame 3441 will further drive the roller 3442 and the first guide rod 3443 to move. At this time, the roller 3442 rolls along the limiting plate 341 in the lifting process, so that the friction between the telescopic rod 343 and the limiting plate 341 changes to rolling friction. At the same time, the first guide rod 3443 is slidingly connected with the cross beam 342, which ensures that the roller 3442 always maintains good contact with the limiting plate 341 and rolls smoothly. The rolling assembly 344 converts the sliding friction between the telescopic rod 343 and the limiting plate 341 into rolling friction through the roller 3442, greatly reducing the friction between the two, thereby effectively reducing the wear degree of the end of the telescopic rod 343 and the limiting plate 341, and prolonging the service life of the parts.

[0045] Referring to Figure 4 and Figure 9 As shown in the drawings: the hair dryer 33 is provided with an air outlet self-opening assembly 36 at the air outlet, and the air outlet self-opening assembly 36 comprises a rectangular frame 361 and a plurality of opening and closing blades 362; the inner cavity of the rectangular frame 361 is in communication with the air outlet; a plurality of opening and closing blades 362 are arranged at equal intervals in the inner cavity of the rectangular frame 361, and the middle part of the opening and closing blade 362 is rotatably connected with the rectangular frame 361.

[0046] When the hair dryer 33 is in the working state, the plurality of opening and closing blades 362 open the inner cavity of the rectangular frame 361; when the hair dryer 33 is in the standby state, the plurality of opening and closing blades 362 close the inner cavity of the rectangular frame 361.

[0047] When the air outlet of the air duct 31 is upward, there is no air flow blowing out of the air outlet when the hair dryer 33 is not started, and the dust in the air will fall into the air duct 31, and when the hair dryer 33 is started next time, the dust in the air duct 31 will be blown out, polluting the air around the simulation walking platform body 1, therefore, the air outlet self-opening assembly 36 is arranged at the air outlet of the air duct 31, during the working process, when the hair dryer 33 is in standby state, since there is no air flow acting on the opening and closing blades 362, the plurality of opening and closing blades 362 will remain in a horizontal state, at this time, the horizontally placed opening and closing blades 362 cooperate with each other to completely close the inner cavity of the rectangular frame 361, which can effectively block the dust in the air from falling into the air duct 31, and avoid the accumulation of dust in the air duct 31, when the hair dryer 33 is started and enters the working state, the hair dryer 33 pushes the air to flow in the air duct 31, and the formed air flow will flow to the air outlet self-opening assembly 36, after the plurality of opening and closing blades 362 are acted on by the air flow, the plurality of opening and closing blades 362 will rotate around the rotation connection point between the middle part and the rectangular frame 361, and gradually rotate from the horizontal state to the vertical state, at this time, the air flow channel is formed between the adjacent two opening and closing blades 362, and the air flow can smoothly pass through the channel, and blow to the actor through the inner cavity of the rectangular frame 361 and the air outlet, the air outlet self-opening assembly 36 realizes the automatic opening and closing of the air outlet in the working and standby states of the hair dryer 33 through the rotation of the opening and closing blades 362, thereby effectively blocking the dust from entering the air duct 31, and avoiding the dust from being blown out to pollute the surrounding air when starting next time.

[0048] Referring to Figure 9 and Figure 10 As shown: the opening and closing blade 362 has a first blade surface 3621 and a second blade surface 3622, the first blade surface 3621 of the opening and closing blade 362 covers the second blade surface 3622 of the opening and closing blade 362 adjacent thereto, and the second blade surface 3622 is provided with a window.

[0049] When the openable and closable blades 362 in the horizontal state are subjected to the action of the airflow, the first leaf surface 3621 and the second leaf surface 3622 of the openable and closable blades 362 are subjected to almost the same force of the airflow, and it is difficult to adjust the state of the openable and closable blades 362 to the vertical state. By opening the window on the second leaf surface 3622 and covering the first leaf surface 3621 of the openable and closable blades 362 on the second leaf surface 3622 of the adjacent openable and closable blades 362, when the air blower 33 is started and the airflow blows to the openable and closable blades 362 in the horizontal state, the airflow will pass through the window on the second leaf surface 3622 and act on the first leaf surface 3621 of the other openable and closable blades 362 because the first leaf surface 3621 is covered on the second leaf surface 3622 of the adjacent openable and closable blades 362. At this time, the force acting on the first leaf surface 3621 is greater than the force acting on the second leaf surface 3622. Under the action of the force difference, the first leaf surface 3621 rotates upward, and the entire openable and closable blades 362 rotate around the rotation connection point of the middle part and the rectangular frame 361, and gradually adjust from the horizontal state to the vertical state. The airflow passage is formed between the adjacent openable and closable blades 362 to ensure that the airflow passes smoothly. When the air blower 33 stops blowing, because the window is opened on the second leaf surface 3622, the mass of the first leaf surface 3621 is greater than the mass of the second leaf surface 3622. Under the action of gravity, the first leaf surface 3621 rotates downward, and the second leaf surface 3622 rotates upward until the adjacent two openable and closable blades 362 are overlapped again, that is, the first leaf surface 3621 is covered on the second leaf surface 3622 of the adjacent openable and closable blades 362. The inner cavity of the rectangular frame 361 is closed. By opening the window on the second leaf surface 3622 and the mass difference between the first leaf surface 3621 and the second leaf surface 3622, the problem that the openable and closable blades 362 in the horizontal state are difficult to rotate to the vertical state under the action of the airflow is solved, and it is ensured that the openable and closable blades 362 can automatically reset to close the inner cavity of the rectangular frame 361 after the air blower 33 stops working.

[0050] Referring to Figure 11 As shown in the figure: the heating mechanism 4 includes a fixed plate 41, two heating plates 42 and an opening structure 43; the fixed plate 41 is fixedly connected with the rotating shaft 32; the two heating plates 42 are rotationally connected with the fixed plate 41; the opening structure 43 is used to control the included angle between the two heating plates 42.

[0051] When the two heating plates 42 are parallel to each other, the heating plate 42 has smaller resistance to the airflow. When the two heating plates 42 are away from each other and the included angle increases, the contact area of the heating plate 42 with the airflow increases.

[0052] If the heating plates 42 are fixedly arranged in the air duct pipe 31, when the heating plates 42 are not needed to heat the air, the heating plates 42 will hinder the air flow of the air duct pipe 31, and affect the speed of the air blowing out of the air duct pipe 31, therefore, when the air needs to be heated, the opening structure 43 drives the two heating plates 42 to move, the heating plates 42 rotate around the rotating connection with the fixed plate 41, so that the two heating plates 42 gradually unfold until the inner cavity of the air duct pipe 31 is covered, at this time, the included angle of the two heating plates 42 increases, and the contact area of the heating plates 42 with the air flow increases, when the air flows in the air duct pipe 31, it will inevitably fully contact the heating plates 42, and then blow to the actor after being heated by the heating plates 42, so as to meet the heating demand, when the air does not need to be heated, the opening structure 43 drives the two heating plates 42 to move close to each other, the two heating plates 42 rotate reversely around the rotating connection with the fixed plate 41, until they are parallel to each other, at this time, the heating plates 42 have smaller hindrance to the air flow, and the air in the air duct pipe 31 can flow smoothly, and the speed of the air blowing out of the air duct pipe 31 will not be affected by the existence of the heating plates 42, so as to ensure the normal blowing effect of the hair dryer 33.

[0053] Referring to Figure 11 and Figure 12 It is shown that the opening structure 43 comprises at least two third guide rods 431, two transmission assemblies 432 and two linear drives 433; the two third guide rods 431 are arranged in parallel, and the third guide rods 431 are connected with the air duct pipe 31; the two transmission assemblies 432 are connected with the two heating plates 42 respectively; and the two linear drives 433 drive the two transmission assemblies 432 to move along the third guide rods 431 respectively.

[0054] Specifically, the transmission assembly 432 comprises a moving block 4321 and a U-shaped plate 4322, the two ends of the moving block 4321 are slidably connected with the two third guide rods 431 respectively, the U-shaped plate 4322 is clamped on the heating plate 42 and slidably connected with the heating plate 42, and one end of the U-shaped plate 4322 is hingedly connected with the moving block 4321.

[0055] When it is needed to adjust the two heating plates 42 to be parallel to each other, the linear driver 433 is started, and the output power of the linear driver 433 drives the moving block 4321 in the transmission assembly 432 to move along the third guide rod 431, and due to the guiding effect of the two third guide rods 431, the moving block 4321 can keep stable translation, and in the moving process of the moving block 4321, the U-shaped plate 4322 hinged to the moving block 4321 drives the heating plate 42 to move, because the heating plate 42 needs to rotate around the rotating connection with the fixed plate 41, so when the U-shaped plate 4322 drives the heating plate 42 to move, the U-shaped plate 4322 will slide relative to the heating plate 42, while always keeping contact with the heating plate 42 to ensure effective power transmission, and finally the two heating plates 42 gradually approach each other until they are in a parallel state, and through the cooperation of the linear driver 433, the transmission assembly 432 and the third guide rod 431, the state adjustment of the heating plate 42 is realized.

[0056] Referring to Figure 11 and Figure 12 , it is shown that the opening structure 43 further comprises a synchronous assembly 434, and the synchronous assembly 434 is arranged between the two transmission assemblies 432 and connected with the two transmission assemblies 432.

[0057] Specifically, the synchronous assembly 434 comprises a fixed shaft 4341 and two transmission arms 4342, the fixed shaft 4341 is vertically arranged between the two moving blocks 4321, and the fixed shaft 4341 is fixedly connected with the two third guide rods 431, the two transmission arms 4342 are cross-arranged, and the middle part of the transmission arm 4342 is rotationally connected with the fixed shaft 4341, and the two ends of the transmission arm 4342 are slidingly connected with the two moving blocks 4321, respectively.

[0058] When the linear driver 433 drives the moving block 4321 to move towards the middle part of the third guide rod 431, the moving block 4321 drives the two transmission arms 4342 to move, because the middle part of the transmission arm 4342 is rotationally connected with the fixed shaft 4341, the two transmission arms 4342 rotate around the fixed shaft 4341, so that the one end of the transmission arm 4342 connected with the moving block 4321 moves away from each other, and the other end of the transmission arm 4342 connected with the moving block 4321 exerts a pulling force on the moving block 4321 towards the middle part of the third guide rod 431, thereby driving the other moving block 4321 to move towards the middle part of the third guide rod 431, when the linear driver 433 drives the moving block 4321 to move towards the end part of the third guide rod 431, the moving block 4321 drives the transmission arm 4342 to rotate around the fixed shaft 4341 through the connection with the two transmission arms 4342, and then drives the other moving block 4321 to move towards the other end part of the third guide rod 431 under the cooperation of the fixed shaft 4341, thereby realizing the reverse synchronous movement of the two moving blocks 4321, and realizing the synchronous movement of the two moving blocks 4321 driven by one linear driver 433.
