The bundle tube assembly 4 includes a rectangular block 401, a rectangular plate 402 is fixedly connected to the edge of the surface of the rectangular block 401, a return spring 403 is provided on the surface of the rectangular plate 402, and an arc-shaped clamping plate 404 is fixedly connected to the end of the return spring 403. The surface of the arc-shaped clamping plate 404 is bonded with an anti-skid pad made of rubber material. The number of the arc-shaped clamping plates 404 is two groups, and they are symmetrically arranged on the surface of the rectangular block 401. The anti-skid pad increases the contact friction between the arc-shaped clamping plates 404 and the suction hose 3, further improving the clamping and fixing effect. A damping hinge is provided at the top of the rectangular block 401, and a protective cover 5 is provided on the surface of the damping hinge. The area of the protective cover 5 is slightly larger than the diameter of the port of the suction hose 3. The protective cover 5 is provided and the damping hinge is flipped to block the port of the suction hose 3, which has a good protective effect and prevents external dust and foreign matter from entering the interior and affecting the use of the sampler. A protrusion is fixedly connected to the center of the back of the protective cover 5, and a limit hole is provided on the surface of the protrusion. Through the provided protrusion, people can hook the limit hole on the surface of the protrusion with their fingers to easily pull up or down the protective cover 5, making it convenient for people to use the protective cover 5. A support rod 9 is provided on the right side of the sample storage tube 1, and a support pad 10 is fixedly connected to the bottom end of the support rod 9. There are two groups of support rods 9 and support pads 10, which are respectively located on the right side of the sample storage tube 1 near the upper and lower ends.

[0028] Embodiment 2;

[0029] On the basis of Example 1, the preferred embodiment of the sampler for cement grinding aid detection provided by the present invention is as follows: Figures 1 to 5 As shown:

[0030] In this embodiment, the bottom area of the support pad 10 is larger than its top area. The support pad 10 is a solid design. The bottom of the support pad 10 is bonded with a non-slip mat. By providing a specially shaped support pad 10, the contact area with the ground is larger. In combination with the use of the non-slip mat, the placement stability of the support pad 10 is further increased. A storage slot 7 is provided on the right side of the sample storage tube 1. The inner side wall of the storage slot 7 is provided with a damping shaft 11. The end of the damping shaft 11 is provided with a connecting column 8. The connecting column 8 is connected to the top of the support rod 9. The damping shaft 11 allows the support pad 10 to be rotated and stored in the storage slot 7 without affecting the sampler when it is in use. A threaded tube is provided at the center of the bottom of the sample storage tube 1, and the inner wall of the top of the suction hose 3 is provided with an internal thread. The threaded tube and the internal thread on the inner wall of the suction hose 3 allow the suction hose 3 and the sample storage tube 1 to be quickly disassembled and replaced.

[0031] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0032] When the sampler is used, the suction hose 3 is inserted between the two sets of arc-shaped clamping plates 404. The arc-shaped clamping plates 404 clamp the suction hose 3 after the return spring 403 contracts and deforms. The protective cover 5 flips over the damping hinge to cover the port of the suction hose 3, which has a good protective effect and prevents external dust and foreign matter from entering its interior and affecting the use of the sampler. Then, the support pad 10 is flipped out of the storage slot 7 through the damping shaft 11 and placed on the desktop, raising the position of the sampler, which has a good supporting effect and avoids the risk of the circular sampler sliding and falling when not in use. At the same time, it avoids the sampler from directly contacting the desktop or the ground after use, causing wear of the sample storage tube 1 and the scale mark 6, affecting its service life. Since the support pad 10 is designed with a special shape, the contact area with the ground is larger, and the use of the anti-slip mat further increases the placement stability of the support pad 10.

[0033] In summary, with the help of the above-mentioned technical solution of the present invention, the suction hose 3 can be clamped and fixed by the bundle tube assembly 4 after the sampler is used, so as to avoid direct contact with the ground or the desktop to cause wear, and the protective cover 5 is used to block the port of the suction hose 3, which has a good protective effect and prevents external dust and foreign matter from entering the interior to affect the use of the sampler. The setting of the support rod 9 and the support pad 10 raises the position of the sampler and has a good supporting effect, avoiding the risk of the circular sampler sliding and falling when not in use, and at the same time avoiding the sampler directly contacting the desktop or the ground after use, causing wear of the sample storage tube 1 and the scale mark 6 to affect its service life.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
