A lifting ring for facilitating the opening of the shielding plate is fixedly connected to the top of the top plate. The shielding plate is located on the front side of the display screen.

[0010] In a possible design, the fixing mechanism includes a rotating handle, a bidirectional lead screw, a sliding rod, two fixing plates, and two side plates. A first rectangular groove and a second rectangular groove are formed in the inner part of the bottom block. Two first rectangular holes are formed in the bottom inner wall of the first rectangular groove. One side of the rotating handle is fixedly connected to a first column. One end of the first column penetrates through one side of the bottom block and is fixedly connected to one end of the bidirectional lead screw. The first column is rotatably connected to the bottom block. The two ends of the bidirectional lead screw are respectively rotatably connected to the two inner walls of the same first rectangular groove. One side of the top of each of the two fixing plates is fixedly connected to a first sliding block. The two first sliding blocks respectively penetrate through the two first rectangular holes and are threadedly sleeved on the same bidirectional lead screw. Two second rectangular holes are formed in the bottom inner wall of the second rectangular groove.

The other side of the top of each of the two fixing plates is fixedly connected to a second sliding block. The two second sliding blocks respectively penetrate through the two second rectangular holes and are slidably sleeved on the same sliding rod. One side of each of the two fixing plates facing away from each other is fixedly connected to a side plate. The two side plates are respectively fixed to the bottom of the same bottom block by bolts. One ends of the two bolts are respectively in close contact with the bottom of the same bottom block.

[0011] In a possible design, anti-slip pads for facilitating the fixing of the equipment connection are fixedly provided on one side of each of the two fixing plates facing each other.

When it is necessary to read the value on the display screen on the device, the top plate is moved upwards through the lifting ring, and the shielding plate is driven to slide up along the slot through the connecting plate until the shielding plate opens the display screen and the value is read. The limit block on the front side of the shielding plate can ensure that the shielding plate will not be separated from the slot. On the contrary, the display screen is shielded and protected to extend the service life of the display screen. When it is necessary to hold and move the device, the transmitter body can be lifted by the holding ring for moving or carrying.
