Monitoring subassembly 2 includes frame shape piece 21, first guide arm 22, sliding block 23 and kickboard 24, and frame shape piece 21 is vertical to be fixed in first casing 1 inner wall one side, and first guide arm 22 is vertical to be fixed inside frame shape piece 21, and the outer peripheral face at first guide arm 22 is established to sliding block 23 cover, sliding block 23 and the inside shape looks adaptation of frame shape piece 21, and sliding block 23 and frame shape piece 21 sliding connection, and one end of kickboard 24 is fixed mutually with one side of sliding block 23.

Two connecting rods 26 are fixed on the top of the floating plate 24, a fixed ball 27 is fixed on the other end of the two connecting rods 26, and a driving rod 28 is horizontally arranged on the fixed ball 27.

The first casing 1 is vertically and fixedly connected with a waist-shaped ring block 29, a placing groove 291 is formed in one side of the waist-shaped ring block 29, and a chain 210 is movably placed in the placing groove 291. The chains 210 move inside the placing grooves 291, and the chains 210 correspond to the shape of the placing grooves 291. During the movement of the chain 210, the chain 210 does not move out of the placing groove 291. The other end of the driving rod 28 is fixedly connected with the chain 210, one side of the first housing 1 is rotatably provided with a rotating rod 211, one end of the rotating rod 211 inside the first housing 1 is fixedly connected with a gear 212, the gear 212 partially extends to the inside of the placing groove 291, and the gear 212 is meshed with the chain 210.

The display module 3 includes a fixed ring 31, a rotating disk 32 and a pointer 33, the fixed ring 31 is fixed on the outer side of the first casing 1, the rotating disk 32 is placed on the inner ring of the fixed ring 31, the rotating disk 32 is rotatably connected with the fixed ring 31, and one end of the rotating rod 211 extends into the fixed ring 31 and is fixed with the rotating disk 32.
