[0032] Specific embodiment three: the second T-shaped sliding piece 3-2 is slidably arranged on the swing piece 2. The swing piece 2 includes a U-shaped swing frame 2-1, two tooth rows 2-2, and two connecting lugs 2-3. The two connecting lugs 2-3 are arranged side by side at the bottom of the finger sleeve 1. The U-shaped swing frame 2-1 is hingedly connected between the two connecting lugs 2-3. The two side inner walls of the U-shaped swing frame 2-1 are respectively provided with a third T-shaped sliding groove 2-1-1. Each third T-shaped sliding groove 2-1-1 is provided with a tooth row 2-2. Each second T-shaped sliding piece 3-2 is slidably arranged in each third T-shaped sliding groove 2-1-1. Each single-toothed tooth piece 3-3 is inserted into each tooth slot of each tooth row 2-2.

[0033] The single-toothed tooth piece 3-3 and the tooth row 2-2 have two kinds of cooperation relationships:

[0034] The first cooperation form is that the single-tooth tooth member 3-3 is inserted into the tooth groove of the tooth row 2-2, at this time, the position of the extension member 3 in the swing member 2 can be fixed, and then the position of the water quality test pen body 5 is fixed.

[0035] The second cooperation form is that the single-tooth tooth member 3-3 is separated from the tooth groove of the tooth row 2-2, at this time, the extension member 3 can be freely stretched and contracted, and then the extension or contraction of the water quality test pen body 5 is realized.

[0036] Specific embodiment four: the specific embodiment three is further limited, and the kit 1 includes a plurality of finger sleeves 1-1 and a connecting plate 1-2. The number of the finger sleeves 1-1 is preferably three. The plurality of finger sleeves 1-1 are arranged side by side on one side of the upper end surface of the connecting plate 1-2. The finger sleeve 1-1 is a flexible elastic sleeve, which is a sleeve body made of an existing elastic finger sleeve product or a material with flexibility and elasticity.

[0037] The fingers are sequentially sleeved in the finger sleeves 1-1, and the utility model is fixed on the hands of the operators. The flexible elastic sleeve of the finger sleeve 1-1 can adapt to the thickness of the fingers of people with different body shapes, and can also more firmly fix the utility model on the hands.

[0038] Specific embodiment five: the specific embodiment three is further limited, and the kit 1 includes a connecting plate 1-2 and a bandage 1-3. The connecting plate 1-2 is arranged below the bandage 1-3. The outer wall of the middle part of the bandage 1-3 is connected with the top of the connecting plate 1-2. The two ends of the bandage 1-3 are detachably connected. When the two ends of the bandage 1-3 are connected, the bandage 1-3 forms a hoop sleeve body matched with the hand. When the two ends of the bandage 1-3 are separated, the bandage 1-3 is a strip-shaped band body.

[0039] The bandage 1-3 is connected end to end to form a hoop sleeve body matched with the hand, which is more convenient to wear, and can also adapt to different widths of the palm.

[0040] Working principle:

[0041] The model of the water quality test pen body 5 is Xima PH8008 pH value water quality detection pen. In use, the fingers are inserted into the finger sleeves 1-1, and the swing member 2 is located below the palm, so that the utility model is worn on the hand. The water quality test pen body 5 is placed between the two clamping heads 4, and the clamping operation of the water quality test pen body 5 is completed.

[0042] When the water quality test pen body 5 needs to be extended, pinch the two operating rods 3-4, each operating rod 3-4 drives each single-toothed tooth piece 3-3 to retract into the second cavity 3-1-1, the single-toothed tooth piece 3-3 is disengaged from the tooth slot of the tooth row 2-2, at this time the second T-shaped slide 3-2 can slide to the designated position in the third T-shaped sliding groove 2-1-1, then release the pinched operating rod 3-4, so that the single-toothed tooth piece 3-3 reinserts into the tooth slot of the tooth row 2-2, realizing position fixation.

[0043] When the water quality of the water source is tested, the palm is parallel to the water surface, the swing piece 2, the extension piece 3 and the water quality test pen body 5 are perpendicular to the water surface, at this time the palm moves downward to extend the water quality test pen body 5 into the water for testing.

[0044] When the palm cannot be parallel to the water surface to ensure that the water quality test pen body 5 is vertically entered into the water, the thumb can be used to control the U-shaped swing frame 2-1, the position of the U-shaped swing frame 2-1 is controlled to adjust the position of the water quality test pen body 5, so that the water quality test pen body 5 can normally enter the water for testing.
