DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-Figure 6 , the utility model provides the following technical solutions:

[0030] Embodiment 1: To solve the problem that when the fixtures for high-frequency vibration tests on the market are being tested, the material will be tested together with the fixtures, which may cause the sample to fall off, and the fallen sample may also be damaged by vibration. Figure 1 -Attached Figure 5 The front and rear sides of the fixed frame 3 are both rotatably connected to the rotating screw 6, and the outer side of the rotating screw 6 is threadedly connected with a group of connecting sleeves 7. The outer side of the connecting sleeve 7 is fixed with a limit block 8, and the top position of the limit block 8 is slidably set inside the guide groove 9. The guide groove 9 is opened inside the left end of the clamp body 10. The left end of the two groups of clamp bodies 10 are rotatably connected to the outside of the connecting shaft 11, and the upper and lower ends of the connecting shaft 11 are fixed on one side of the fixed frame 3. The rotation directions of the two groups of clamp bodies 10 are relatively set. The connecting sleeve 7 forms a sliding structure between the limit block 8 and the outer side of the guide groove 9, and the rotation angle of the clamp body 10 is 0-60°.

[0031] When one side of the clamp body 10 is close to the side of the sample of the high-frequency vibration test, by rotating the screw 6, the connecting sleeve 7 threadedly connected to the outer side of the screw 6 will drive the clamp body 10 to move through the limit block 8. At this time, the two groups of clamp bodies 10 will rotate relative to each other through the connecting shaft 11. At this time, the clamp body 10 provides a squeezing force to the limit block 8 during the rotation process, causing the connecting sleeve 7 to slide through the limit block 8, so that the two groups of clamp bodies 10 can limit the sample of the high-frequency vibration test.

[0032] Embodiment 2: To facilitate the adjustment of the position of the clamp, please refer to the attached Figure 1 and attached Figure 2 , including a fixture body 1, a group of electric push rods 2 are fixed at the left and right ends of the top of the fixture body 1, and a group of fixed frames 3 are fixed at the output ends of the electric push rods 2; it also includes: a group of sliders 4 are fixed at the front and rear bottom positions of the fixed frame 3, and the bottom position of the slider 4 is slidably set in the slide groove 5 opened at the top of the fixture body 1. After placing the sample that needs high-frequency vibration test at the top position of the fixture body 1, by starting the electric push rod 2 fixed at one side of the fixture body 1, the output end of the electric push rod 2 drives the fixed frame 3 to move, resulting in the fixed frame 3 will drive the clamping mechanism to move, and the fixed frame 3 will slide inside the slide groove 5 through the slider 4, so that the fixed frame 3 can move stably.

[0033] Embodiment 3: This embodiment is different from Embodiment 1 in that an expansion mechanism can be added to prevent the sample that needs to undergo high-frequency vibration testing from falling off. Figure 1 , Attachment Figure 2 and attached Figure 6 The end of the rotating screw rod 6 extends into the interior of the fixing frame 3 and is threadedly connected with a set of threaded sleeves 12. The end of the threaded sleeve 12 is attached to one side of the air bag 13. One side of the air bag 13 is connected to the top of the attachment pad 15 through a connecting pipe 14. The attachment pad 15 and the air bag 13 are both made of elastic rubber, and the elastic force of the attachment pad 15 is greater than the elastic force of the air bag 13. The connecting tube 14 is a rubber hose, and the connecting tube 14 is arranged on the top outer side of the clamp body 10. The side of the fitting pad 15 that contacts the sample is a wear-resistant setting. When the rotating screw 6 is rotating, the rotating screw 6 can make the threaded sleeve 12 slide inside the fixed frame 3, so that the threaded sleeve 12 will squeeze one side of the air bag 13, so that the gas inside the air bag 13 will be transported to one side of the fitting pad 15 through the connecting tube 14, so that the fitting pad 15 will expand at one side of the clamp body 10, so that one side of the clamp body 10 is fitted to the outside of the high-frequency vibration test sample. At this time, a further anti-falling setting can be achieved through the wear-resistant setting.
