[0024] A test tube buckle comprises a fixing handle 1, a clamping portion 200, a hand pressure handle 300 and a clamping piece 4; wherein the fixing handle 1 is used to fix the test tube buckle on an air release value measuring instrument; the clamping portion 200 is used to clamp and fix a heat-resistant jacketed glass test tube; the hand pressure handle 300 is used to tighten the clamping portion 200 when clamping the heat-resistant jacketed glass test tube; the clamping piece 4 is used to clamp the two sides of the hand pressure handles on both sides to better fix the heat-resistant jacketed glass test tube.

[0025] The fixed handle 1, the clamping part 200, the hand pressure handle 300 and the clamping part 4 are integrated and are all made of spring steel sheet metal. The use of spring steel sheet metal makes the fixed handle 1, the clamping part 200, the hand pressure handle 300 and the clamping part 4 have a certain elasticity, and can clamp and fix the heat-resistant jacketed glass test tube whose size is larger than the fixed size of 2 mm, and at the same time have a certain corrosion resistance and high heat resistance.

[0026] The fixing handle 1 is a hollow U-shaped one with an open side. Figure 1 to Figure 2As shown, a fixing hole 5 is provided on the fixing handle 1. Figure 1 to Figure 2 As shown, the fixing hole 5 is opened on the side of the fixing handle 1 close to the air release value measuring instrument, that is, the bottom of the U shape, and the fixing holes 5 are two symmetrical and arranged on the same horizontal line. Such an arrangement can better fix the quick clip on the air release value measuring instrument without causing the quick clip to tilt, thereby ensuring the stability of the quick clip fixed on the air release value measuring instrument.

[0027] The clamping part 200 is fixedly arranged on a side away from the fixing hole 5, so that the clamping part 200 has a certain distance from the air release value measuring instrument, such as Figure 1 As shown, the shape of the trial clamping part 200 is a hollow circle with openings on both sides, and the clamping part 200 is divided into two parts, the upper and lower parts are an upper clamping member 201 and a lower clamping member 202, one end of the upper clamping member 201 is fixedly connected to the upper side of the open end of the fixed handle 1, and one end of the lower clamping member 202 is fixedly connected to the lower side of the open end of the fixed handle 1. The fixed connection between the upper clamping member 201 and the lower clamping member 202 and the open end of the fixed handle 1 is provided with a fillet 600, and the fillet 600 is two fillets, fillet 601 and fillet 602, as shown in FIG. Figure 2 As shown, the fillets 601 and 602 are symmetrically arranged so that the fixed connection between the clamping portion 200 and the fixed handle 1 is arc-shaped. This arrangement is to avoid the heat-resistant jacketed glass test tube and the fixed connection between the clamping portion 200 and the fixed handle 1 from colliding when the heat-resistant jacketed glass test tube is fixed, thereby preventing the heat-resistant jacketed glass test tube from being broken.

[0028] like Figure 1 As shown, the upper clamping member 201 and the lower clamping member 202 are in the form of sheets with a certain width, such as Figure 1 As shown, such a configuration is to better fit the heat-resistant jacketed glass test tube, and also to increase the contact area between the upper clamping member 201 and the lower clamping member 202 and the heat-resistant jacketed glass test tube, increase the friction force, and better fix the heat-resistant jacketed glass test tube.

[0029] The hand pressure handle 300 is fixedly arranged at the right end of the clamping portion 200. Figure 1 to Figure 2As shown, the hand pressure handle 300 is also divided into two parts, the upper and lower parts are an upper handle 301 and a lower handle 302. The left end of the upper handle 301 is fixedly connected to the right end of the upper clamping member, and the left end of the lower handle 302 is fixedly connected to the right end of the lower clamping member 202. The upper handle 301 and the lower handle 302 are symmetrically arranged and bent inward, but there is a certain distance between the bent parts of the upper handle 301 and the lower handle 302, and they do not touch each other. This arrangement is to allow the heat-resistant jacketed glass test tube that is 2 mm larger than the preset size to be fixed.

[0030] In order to be able to clamp and fix the heat-resistant jacketed glass test tube that is 2 mm smaller than the preset size, a clamping piece 4 is provided on the hand pressure handle 300. Figure 1 to Figure 2 As shown, one end of the clamping member 4 is fixedly arranged on the upper handle 301 or the lower handle 302 of the hand pressure handle 3, and is located at the inward portion of the hand pressure handle 300. The other end of the clamping member 4 is bent inwardly and is used to clamp the two sides of the hand pressure handle 300 together. The clamping member 4 clamps the inward portion of the hand pressure handle 300. This arrangement shortens the clamping distance and saves the force when the hand presses inward.

[0031] In order to make the clamping smoother, chamfers are provided on the hand pressure handle. There are two chamfers and they are symmetrically arranged. The chamfers are chamfers 701 and chamfers 702. The chamfers have the following function. When the size of the heat-resistant jacketed glass test tube to be clamped and fixed is small, the upper handle 301 and the lower handle 302 are pressed inward by hand. The upper handle 302 and the lower handle 302 are guided by the chamfers 701 and 702, so that the inner bend of the hand pressure handle 300 is clamped in the clamping part 4.

[0032] As required, the clamping member 4 can be any component such as a barb, a snap, etc. that can clamp the upper handle 301 and the lower handle 302 together.

[0033] When using the utility model: in order to better fix the heat-resistant jacketed glass test tube, two of the utility models are needed. The utility model is fixed together with the air release value measuring instrument through the fixing hole 5. After the fixing is completed, first push the heat-resistant jacketed glass test tube forward into the two clamping parts 200, hold the heat-resistant jacketed glass test tube with one hand, and make the heat-resistant jacketed glass test tube in the corresponding position. If the size of the heat-resistant jacketed glass test tube is large, there is no need to clamp and lock the upper handle 301 and the lower handle 302 together. Through the utility model The new elastic feature can realize fixing the heat-resistant jacketed glass test tube; if the size of the heat-resistant jacketed glass test tube is small, one hand holds the heat-resistant jacketed glass test tube to keep the heat-resistant jacketed glass test tube in the corresponding position, and the other hand pinches the upper handle 301 and the lower handle 302 and presses them inward, so that the upper handle 301 or the lower handle 302 is guided by the chamfer and slides into the clamping part 4 to be locked, while also reducing the range of the clamping storage of the clamping part 2, thereby realizing the card transfer to fix the smaller size of the heat-resistant jacketed glass test tube.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical scheme and concept of the present invention within the scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
