[0024] Refer to Figures 1 to 2 , Figure 1 which is the front view of the present utility model, Figure 2 and which is the perspective view of the present utility model. A sample cutting device for a vehicle interior formaldehyde emission test sample provided by the present utility model includes a base 1, an upper baffle 2, a cutting knife 3, and a threaded support rod 4. Guide rods 11 are provided on both sides of the base 1. The guide rods 11 are preferably smooth stainless steel guide rods. The upper baffle 2 is movably connected to the guide rods 11. A cutting knife 3 is provided at the lower part of the upper baffle 2. The cutting knife 3 is detachable to ensure convenient replacement after the cutting knife 3 is damaged. A knife groove 12 adapted to the cutting knife 3 is provided on the base 1. A threaded support rod 4 passes through the middle of the upper baffle 2 and is connected to the threaded hole of the upper baffle 2. A bearing 13 is provided at the middle part of the base 1. The bottom of the threaded support rod 4 is connected to the bearing 13 to realize the rotation function of the threaded support rod 4. A handle 41 for rotating the threaded support rod 4 is provided on the upper part of the threaded support rod 4. Rotating the threaded support rod 4 can drive the upper baffle 2 to move up and down along the guide rods 11. When moving downward, the cutting knife 3 moves downward accordingly. When the cutting knife 3 enters the knife groove 12, the sample cutting is completed.

[0025] In one embodiment, a clamp (not shown) for clamping the test sample is provided on the base 1. A rubber plug 111 is provided at the upper part of the guide rod 11 to prevent the upper baffle 2 from accidentally falling off.

[0026] In one embodiment, plastic handles 21 are provided on both sides of the upper baffle 2 for convenient movement.

[0027] In one embodiment, the length of the cutting knife 3 is 100 mm and the width is 40 mm, which can meet the requirements of the formaldehyde emission content detection sample. The length of the knife groove 12 is 103 mm and the width is 43 mm. The size of the cutting knife 3 is slightly larger than that of the cutting knife 3 to prevent the cutting knife 3 from rubbing against both sides of the knife groove 12 and damaging the blade; a plastic knife sheath 31 is provided on the cutting knife 3 to prevent scratching.

[0028] In one embodiment, at least three cutting knives 3 are respectively provided on both sides of the threaded support rod 4 to ensure that the sample cutting device of the present invention can cut at least 6 parallel samples in parallel at one time.

[0029] The following will refer to Figures 1 to 2 to illustrate the working principle of the present invention.

[0030] When cutting samples, the upper baffle 2 is lifted to a certain height by rotating the handle 41 counterclockwise, the sample is laid flat on the base 1, the plastic knife sheath 31 is removed, and the handle 41 is rotated clockwise to lower the upper baffle 2. When the cutting knife 3 contacts the sample, continuing to rotate the handle 41 can achieve cutting, and multiple parallel samples can be cut in parallel to ensure the stability of the test results. A sample cutting device for an automobile interior formaldehyde emission test sample of the present invention has a simple and reasonable structure, is convenient to use, has a high sample cutting efficiency, can cut multiple parallel samples in parallel, has a small error, ensures the stability of the test results, can perform flat cutting on different thicknesses and soft samples, the cutting knife is replaceable, and the maintenance is convenient.
