The detector body 1 can adopt a handheld pump-suction gas detector of model MS500. The base 2 includes a bottom plate 21, side hooks 22, a top plate 23, a locking device 24 and a wrist strap 25. The side hooks 22 have four sides, and the side hooks 22 are integrally connected to both sides of the bottom plate 21. The upper ends of the side hooks 22 are bent toward the center line of the bottom plate 21. The top plate 23 is integrally connected to the top of the bottom plate 21. The locking device 24 includes an elastic card group and a locking card group. A card slot is provided at the lower portion of the bottom plate 21, and a spring 247 is provided in the card slot. The lower portion of the top plate 23 is connected to the spring 247, and the top plate 23 can pop out of the upper portion of the card slot through the spring 247. The locking card group includes a locking baffle 242 and an unlocking assembly 243 connected to the locking baffle 242. The locking baffle 242 prevents the card plate 241 from popping out when the card plate 241 is pressed down into the card slot. The wristband 25 is connected to the bottom plate 21.

[0025] In this embodiment, a surface of the clamping plate 241 close to the lower side of the bottom plate 21 is an inclined surface.

[0026] In this embodiment, a boss 244 is integrally provided on the upper portion of the card slot to prevent the card plate 241 from completely popping out.

[0027] In this embodiment, a protrusion 245 is integrally provided on one side of the card plate 241 close to the locking baffle 242, a transverse groove is provided on the inner side of the card groove, a spring 246 is provided in the transverse groove, the locking baffle 242 abuts against the spring 246 and is slidably connected in the transverse groove, and the right end of the card plate 241 abuts against the card plate 241.

[0028] In this embodiment, an inclined surface is provided at one end of the locking baffle 242 abutting against the card plate 241 , and when the card plate 241 is pressed down to be flush with the upper end of the card slot, the boss 244 is located above the locking baffle 242 .

[0029] In this embodiment, there are two groups of locking baffles 242 , and the two groups of locking baffles 242 are respectively disposed on both sides of the bottom plate 21 .

[0030] In this embodiment, a groove is provided between the two groups of locking baffles 242, and sliding grooves connecting the transverse grooves are provided on both sides of the groove. The unlocking component 243 is a sliding rod, and both ends of the sliding rod are connected to the locking baffles 242 and are slidably connected in the sliding grooves.

[0031] In this embodiment, two transverse through holes are provided on the bottom plate 21, and there are two wristbands 25, which are respectively passed through the through holes. The wristbands 25 can be made of elastic material or buckles can be provided on the wristbands 25 to facilitate the adjustment of the length so that they are suitable for different arm circumferences.

[0032] In this embodiment, a locking screw 3 is provided at the bottom of the bottom plate 21, a threaded hole is provided at the lower part of the through hole on the bottom plate 21, and a fixing hole corresponding to the threaded hole is provided on the wrist strap 25. The locking screw 3 passes through the wrist strap 25 in the through hole from the lower side of the bottom plate 21 and is threadedly connected to the bottom plate 21.

[0033] In this embodiment, a reserved opening 4 is formed on the top plate 23 .

[0034] When the utility model is in use, the detector body 1 is pushed from the lower part of the upper side of the bottom plate 21 into the side hook claws 22. When the detector body 1 abuts against the upper inclined surface of the card plate 241, the card plate 241 is pushed downward. When the detector body 1 is completely pushed into the side claws and the pump suction port at the upper end of the detector body 1 is located at the reserved port 4, the card plate 241 is ejected upward by the elastic potential energy of the spring 247 and abuts against the lower part of the detector body 1. At this time, the detector body 1 is clamped on the base 2. By clamping the wristband 2 5 is set on the forearm, and the length of the wristband 25 is adjusted to fix it. If the detector body 1 needs to be removed, the upper side of the card plate 241 is pressed at this time, so that the boss 244 on the card plate 241 pushes the locking baffle 242 and compresses the spring 246. When the boss 244 is located below the locking baffle 242, the spring 246 pushes the locking baffle 242 to be stuck on the upper part of the boss 244. At this time, the locking baffle 242 is locked and no longer pops out to block the detector body 1. At this time, the detector body 1 can be taken out with one hand.
