[0027] A display screen 6 is installed on the left side of the front end of the control box 3, a control button 12 is arranged on the right side of the front end of the control box 3, a protective plate 5 is arranged at the front end of the display screen 6, a slider 11 slides up and down inside the limiting slide groove 4, and movable casters 13 are respectively installed on both sides and both ends of the bottom end of the base 1;

[0028] Specifically, Figure 1 and Figure 3 As shown, the protective plate 5 is made of a transparent material. The protective plate 5 can protect the display screen 6. It can not only prevent dust and impurities from floating on the surface of the display screen 6, but also prevent external force from colliding with the surface of the display screen 6 to cause the display screen 6 to be damaged and broken. When the protective plate 5 needs to be separated from the surface of the display screen 6, pull the handle 10, and the handle 10 drives the protective plate 5 to rise through the connecting rod 9, so that the protective plate 5 can be conveniently separated from the front end of the display screen 6 to use the display screen 6.

[0029] Embodiment 2: A sleeve 7 is installed on the left side of the top of the control box 3, an adjusting rod 23 is fixedly connected to the left side of the bottom end of the connecting plate 8, a pull block 25 is provided on the top of the left side of the sleeve 7, a limiting rod 22 is fixedly connected to the right side of the pull block 25, a spring 21 is fixedly connected between the pull block 25 and the sleeve 7, and limiting grooves 24 are respectively provided at the bottom and top of the left side of the adjusting rod 23, the limiting rod 22 is embedded in the limiting groove 24, and the adjusting rod 23 is fixed to the inside of the sleeve 7 through the limiting rod 22 and the limiting groove 24;

[0030] Specifically, Figure 1 and Figure 4 As shown, when the connecting plate 8 is raised, the adjusting rod 23 will slide up and down inside the sleeve 7. When the protective plate 5 rises to a suitable height, the pull block 25 is released, and the spring 21 causes the limiting rod 22 to rebound to the inside of the limiting groove 24 through its own elasticity, thereby limiting and fixing the adjusting rod 23 to prevent the adjusting rod 23 from accidentally driving the display screen 6 and the protective plate 5 down and accidentally injuring the user.

[0031] Embodiment 3: A fixing plate 17 is provided at the bottom end of the base 1, a limiting plate 15 is provided at the bottom end of the fixing plate 17, a threaded rod 16 is provided between the fixing plate 17 and the limiting plate 15, a turning handle 19 is fixedly connected to the right side of the threaded rod 16, connecting blocks 14 are provided on both sides of the outside of the threaded rod 16, hinge blocks 20 are installed at both ends of the connecting block 14, a hinged rod 18 is movably hinged between the hinged block 20 and the fixing plate 17, the hinged rod 18 is movably hinged on both sides between the limiting plate 15 and the hinged block 20, a protective pad is provided at the bottom end of the limiting plate 15, external threads are provided on both sides of the outside of the threaded rod 16, the threads on both sides of the outside of the threaded rod 16 are opposite, and the connecting block 14 and the threaded rod 16 cooperate with each other;

[0032] Specifically, Figure 1 and Figure 2 As shown, after placing the device in a suitable position, turn the handle 19, and the handle 19 drives the threaded rod 16 to rotate. Since the threaded rod 16 and the connecting block 14 cooperate with each other, and the hinged rod 18 is movably connected to the two ends of the connecting block 14, the rotation of the threaded rod 16 can make the hinged rod 18 drive the limit plate 15 to rise and fall. After the limit plate 15 drops to a certain height, it will rest on the ground, thereby limiting the movable caster 13, improving the stability of the device, and preventing the movable caster 13 from accidentally driving the device to move.

[0033] Working principle: When the utility model is used, the device is pushed, and the handle 19 is turned after the device is moved to a suitable position. The handle 19 drives the threaded rod 16 to rotate. Since the threaded rod 16 and the connecting block 14 cooperate with each other, and the hinged rod 18 is movably connected to the two ends of the connecting block 14, the rotation of the threaded rod 16 can make the hinged rod 18 drive the limit plate 15 to rise and fall. After the limit plate 15 drops to a certain height, it will rest on the ground, so that the movable caster 13 can be limited to prevent the movable caster 13 from accidentally driving the device to move. The protective plate 5 is a transparent material, and the protective plate 5 can protect the display screen 6, which can not only prevent dust and impurities from floating on The surface of the display screen 6 can also prevent external force from colliding with the surface of the display screen 6 and causing the display screen 6 to be damaged and broken. When the display screen 6 needs to be exposed, pull the handle 10, and the handle 10 drives the protective plate 5 to rise through the connecting rod 9, so that the protective plate 5 can be easily separated from the front end of the display screen 6 and the display screen 6 can be exposed. When the connecting plate 8 is raised, the adjusting rod 23 will slide up and down inside the sleeve 7. When the protective plate 5 rises to a suitable height, release the pull block 25, and the spring 21 uses its own elasticity to make the limiting rod 22 rebound to the inside of the limiting groove 24, so that the adjusting rod 23 can be limited and fixed to prevent the adjusting rod 23 from accidentally driving the display screen 6 and the protective plate 5 to fall.
