Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] As a technical optimization solution of the present invention, a rope 3 is fixedly connected to the lower surface of the movable plate 204, and the lower end of the rope 3 is fixedly connected to a limit ring 303. A limit mechanism is provided on one side of the limit ring 303. When the staff wants to check a certain pressure transmitter 207 separately, the rope 3 and the limit ring 303 facilitate the staff to pull down the pressure transmitter 207 for inspection and maintenance.

[0022] As a technical optimization solution of the present invention, the limiting mechanism includes a horizontal plate 301, and the two ends of the horizontal plate 301 are fixedly connected to the inner surface of the support seat 1, and one side surface of the horizontal plate 301 is fixedly connected to the limiting rod 302, and one end of the limiting rod 302 is aligned with the limiting ring 303. The limiting ring 303 and the rope 3 can be limited by the limiting rod 302 and the horizontal plate 301 to prevent adjacent ropes 3 from being entangled together and affecting subsequent use.

[0023] As a technical optimization solution of the present invention, the support plate 2 is internally slidably connected to a multi-stage telescopic rod 202, and the upper end of the multi-stage telescopic rod 202 is fixedly connected to the limiting plate 201, and the lower end of the multi-stage telescopic rod 202 is fixedly connected to the upper surface of the movable plate 204. The movable plate 204 can be limited by the multi-stage telescopic rod 202 and the limiting plate 201 at the upper end of the multi-stage telescopic rod 202, thereby improving the stability of the movable plate 204 and the pressure transmitter 207, and preventing the movable plate 204 and the pressure transmitter 207 from shaking during use.

[0024] As a technical optimization solution of the present invention, the driving mechanism includes a driving box 105, and the driving box 105 is fixedly connected to the rear surface of the support base 1, the upper end of the driving box 105 is fixedly connected to the adjusting box 104, and the adjusting box 104 is communicated with the driving box 105, the internal rotation of the adjusting box 104 is connected to the worm 107, and the side surface of the worm 107 is meshed with the worm wheel 106, one side surface of the worm wheel 106 passes through the driving box 105 through the rotating shaft and is fixedly connected to the one side surface of the gear 101, one end of the worm 107 passes through the adjusting box 104 and is fixedly connected to the handle 108, which facilitates the rotation of the driving gear 101, and drives the gear lifting frame 102 up and down through the teeth 103, thereby making it convenient for the staff to uniformly adjust the height of the pressure transmitter.

[0025] When the present invention is in use, when the staff needs to check multiple groups of pressure transmitters 207 as a whole, the staff first rotates the worm 107 through the handle 108, so that the worm 107 will drive the worm gear 106 inside the drive box 105 to rotate, and then the worm gear 106 drives the gear 101 to rotate through the rotating shaft, and the gear 101 drives the gear lifting frame 102 to move downward through the teeth 103 on the inner surface of the gear lifting frame 102, so that the support plate 2 at the upper end of the gear lifting frame 102 will move downward together, and the staff can check multiple groups of pressure transmitters 207 at the same time. When the inspection is completed, the staff rotates the handle 108 in the opposite direction, so that the gear lifting frame 102 rises back to its original position. When the staff needs to check a group of pressure transmitters 207 separately, at this time, they only need to pull the lower end of the rope 3 through the limit ring 303 to enable the movable plate 204 to move downward. At this time, the movable plate 204 will drive a group of pressure transmitters 207 to move downward, so that it is convenient for the staff to check a group of pressure transmitters 207 separately.
