[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0022] like Figures 1-2 As shown, the oscillator stand provided in this embodiment includes an upper frame 1 and a lower frame 2, which are connected by a fixing rod 3. The lower frame 2 has a pair of connecting posts 4 at its bottom for connection to the oscillator host. The upper frame 1 has two rows of positioning holes 5, each positioning hole 5 has a notched circular sleeve 6 at its bottom, and each notch is equipped with an arc-shaped pressure plate 7. A guide assembly 8 is provided between the two rows of circular sleeves 6. Combined with… Figures 3-6 As shown, the guide assembly 8 contains a guide rod 81, and a drive plate 9 is provided on the guide rod 81 for each position of the circular sleeve 6. The two ends of the drive plate 9 are respectively fixed to the arc-shaped pressure plate 7 on the corresponding side. The upper frame 1 is also provided with a pressing drive assembly, which contacts one end of the guide rod 81. A compression spring 82 is provided between the other end of the guide rod 81 and the side plate of the upper frame. The lower frame 2 has a circular hole 21 directly below each positioning hole 5.

[0023] In this structure, the sample tube is inserted into the positioning hole, and its bottom is limited by a circular hole in the lower part of the holder. The diagram shows eight positioning holes, allowing for the simultaneous placement of eight sample tubes. The sample tubes are generally of relatively uniform specifications. The bottom of the positioning hole is a circular sleeve, the inner diameter of which roughly matches the sample tube. The sleeve also has a certain height to limit the position of the sample tube, ensuring it remains vertical and does not become eccentric. Additionally, the side wall of the circular sleeve has a notch, where an arc-shaped pressure plate is positioned. A silicone layer can be further added to the inner sides of the circular sleeve and the arc-shaped pressure plate to increase friction.

[0024] The function of this product is as follows: When the pressing drive assembly is pressed, it compresses the guide rod, causing the guide rod, drive plate, and arc-shaped pressure plate to move backward as a whole. The compression spring is further compressed, allowing the sample tube to be placed into the positioning hole. Releasing the pressing drive assembly causes the guide rod to return to its original position under the force of the compression spring, and the arc-shaped pressure plate further compresses the sample tube, thus securing it. To remove the sample tube, simply press the pressing drive assembly again; the operation is very simple.

[0025] In this structure, the guide assembly 8 serves to provide overall movement guidance for the guide rod 81 and the drive plate 9. (Combined with...) Figure 4 , 6 As shown, the guide assembly 8 includes a pair of spaced-apart parallel plates 83, with a guide rod 81 positioned between the parallel plates 83. Each parallel plate 83 has several slots 84, the width of which is greater than the width of the drive plate 9. T-shaped strips 85 are fixed to the openings of the parallel plates 83, and these T-shaped strips 85 contact the drive plate 9. As can be seen from the figure, a guide groove is formed between the T-shaped strip 85 and the slots 84. The drive plate is positioned within this guide groove, limiting its movement to a small horizontal forward and backward range, thus ensuring stability. All drive plates and guide rods form an integral structure.

[0026] In addition, this embodiment also implements the function of pressing the pressing drive component to drive the guide rod to move. Combined with... Figure 1 , 7 As shown in Figure 8, the pressing drive assembly includes an upper pressure plate 101 and a push plate 102. The pressure plate 101 has a pair of round rods 103 at its bottom, and the round rods 103 pass through the upper frame and are fixed to the push plate 102. A driving block 108 is fixed downward in the middle of the push plate 102. The driving block 108 is narrow at the bottom and wide at the top, with a smooth transition in the middle. The bottom of the upper frame 1 also has a guide plate 104. The guide plate 104 has a guide opening 105 that matches the shape of the lower part of the driving block 108. The lower part of the driving block 108 passes through the guide opening 105. The side of the driving block 108 abuts against the guide rod 81. There are also short rods 106 at the bottom of both sides of the push plate 102. A push spring 107 is sleeved on the short rod 106, and the bottom of the push spring 107 abuts against the guide plate 104.

[0027] During operation, pressing the upper pressure plate causes the upper plate to drive the push plate and drive block to move downwards under the guidance of the round rod and guide opening. The push spring is compressed, and during this downward movement, the smooth transition surface of the drive block presses against the guide rod, causing the guide rod 81 to move. When the upper pressure plate is released, the drive block returns to its initial position under the pushing force of the push spring. Under the force of the compressed spring, the arc-shaped pressure plate presses the template tube tightly. Additionally, as... Figure 5 , 6 As shown, a plunger 11 is screwed into the side plate of the upper shelf 1. The plunger abuts against the compression spring 82. By rotating and adjusting the plunger 11, the pushing force of the compression spring on the guide rod, that is, the squeezing force on the side wall of the sample tube, can be adjusted.

[0028] Finally, as a preferred embodiment, one end of the guide rod 81 is fixed with a long strip ring 86, and the drive block 108 is located inside the long strip ring 86. The long strip ring can also play a certain guiding role, ensuring the stability of the guide rod's movement.

[0029] The above merely describes preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
