The positions of the first alignment block and the first alignment groove are fixed, and the first alignment block and the first alignment groove can be used as mutual references, so that the first alignment block and the first alignment groove will reduce the width of the reference object that needs to be observed when assembling the first body, thereby increasing the assembly speed. The second body is then assembled in the middle position, leaving the sliding groove to leave a track for the movement of the slide. After the stage is assembled, the mobile car is placed behind the background board, allowing the actor to stand on the lifting platform to rise to the stage. When it is time to go on stage, the actor stands on the moving board, and then the first motor and the second motor are started to make the slide slide to the front end of the stage.

[0008] Through the above technical solution, since the stage is assembled by splicing, the structural stability is poor, so the guard frame at the edge of the stage can make the stage assembly more stable. After the stage is surrounded by the corner frame and the frame, the two are rigidly connected by the connecting lock, so as to achieve the reinforcement effect. When fixed by the connecting lock, the first screw and the second screw are arranged at both ends of the threaded block. The first handle and the second handle are turned with both hands so that the left and right ends can be fixed at the same time, thereby increasing the fixing speed and facilitating installation.
[0009] Preferably, a background plate is fixedly connected to the outer wall of the first main body.

[0019] Preferably, a hub is provided on the inner wall of the base.
[0020] Through the above technical solution, the base is moved through the wheel hub, so that the mobile vehicle can change its position better.
[0021] Preferably, the lifting platform comprises a sliding plate, and an outer wall of the sliding plate is fixedly connected with a clamping block.
[0022] Through the above technical solution, the clamping block is clamped with the sliding frame.
[0023] A control method for a stage with a mobile module comprises the following steps:
[0024] S1. The first alignment block and the first alignment groove on the first body can speed up the mutual assembly of multiple first bodies. The positions of the first alignment block and the first alignment groove are fixed, and the first alignment block and the first alignment groove can be used as mutual references. In this way, the first alignment block and the first alignment groove will reduce the width of the reference object that needs to be observed when assembling the first body, thereby increasing the assembly speed. The second body is then assembled in the middle position, leaving a sliding groove to leave a track for the movement of the slide. After the stage is assembled, the mobile car is placed behind the background board, allowing the actors to stand on the lifting platform to rise to the stage. When it is time to go on stage, the actors stand on the moving board, and then the first motor and the second motor are started to make the slide slide to the front end of the stage.
[0025] S2. Since the stage is assembled by splicing, the structural stability is poor, so the guard frame on the edge of the stage can make the stage assembly more stable. After the stage is surrounded by the corner frame and the frame, the two are rigidly connected by the connecting lock to achieve the reinforcement effect. When fixed by the connecting lock, the first screw and the second screw are installed at both ends of the threaded block. Turning the first handle and the second handle with both hands can fix the left and right ends at the same time, thereby increasing the fixing speed and facilitating installation.
[0026] S3. The backdrop is usually used as the background of the stage, and a back door is left for people to enter and exit. The curtain on the curtain rod serves the purpose of closing and opening, and serves the purpose of transition during performances.
[0027] S4. Since the sliding groove is opened on the stage, it needs to be sealed during the performance. Activating the hydraulic rod can seal the sliding groove with the plate on the hydraulic rod.
[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] 1. The first alignment block and the first alignment groove on the first body can speed up the mutual assembly of multiple first bodies. The positions of the first alignment block and the first alignment groove are fixed, and the first alignment block and the first alignment groove can be used as mutual references. In this way, the first alignment block and the first alignment groove will reduce the width of the reference object that needs to be observed when assembling the first body, thereby increasing the assembly speed.
[0030] 2. Assemble the second main body in the middle position, leaving a sliding groove to leave a track for the movement of the slide. When the stage is assembled, place the mobile car behind the background board, let the actors stand on the lifting platform to rise to the stage, and when they need to go on stage, the actors stand on the moving board, and then start the first motor and the second motor to make the slide slide to the front of the stage.
[0031] 3. Since the stage is assembled by splicing, the structural stability is poor, so the guard frame on the edge of the stage can make the stage assembly more stable. After the stage is surrounded by the corner frame and the frame, the two are rigidly connected by the connecting lock to achieve the reinforcement effect. When fixed by the connecting lock, the first screw and the second screw are installed at both ends of the threaded block. Turning the first and second handles with both hands can fix the left and right ends at the same time, thereby increasing the fixing speed and facilitating installation.
