The specific connection means should refer to the following description, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well known in this field.

[0021] The metal material axial tensile fatigue test device provided in this embodiment is as follows: Figure 1 As shown, it includes a main body component and a blocking component, wherein:

[0022] The main component includes a console 1, the top of which is connected to a bracket 2, the top of which is connected to a support plate 3, a vertical guide rod 4 is stacked on the support plate 3, and a top plate 5 is connected to the guide rod 4. The ends of the top plate 5 and the support plate 3 that are close to each other are connected to a clamp 6, which is a cylindrical structure.

[0023] The blocking member includes an annular groove 7, whose inner diameter is larger than that of the clamp 6, formed at the top of the support plate 3. A semicircular baffle 8 is slidably engaged with the annular groove 7 and is rotatable within the annular groove 7. The annular groove 7 and the semicircular baffle 8 allow the semicircular baffle 8 to be rotated to the front during the stretching process of the metal material to block the debris released when the metal material breaks, preventing the debris from causing harm to the tester.

[0024] In addition, if Figure 3 As shown, the top of semicircular baffle 1 (8) is topped by semicircular baffle 2 (9), which differs only in height. A snap-fit ​​mechanism 10 connects the two. Furthermore, snap-fit ​​mechanism 10 allows semicircular baffle 2 (9) to be continuously joined vertically. Specifically, snap-fit ​​mechanism 10 includes multiple snap-fit ​​holes 1001, evenly distributed along the arcs of both semicircular baffles 1 (8) and 2 (9). Furthermore, the bottom of semicircular baffle 2 (9) is connected to multiple snap-fit ​​posts 1002 that mate with snap-fit ​​holes 1001. This allows the height of semicircular baffle 1 (8) to be adjusted based on the length of the metal material and the length of the stretch, allowing it to completely block the metal material in the vertical direction.

[0025] In addition to the above:

[0026] One, such as Figure 3 As shown, the bottom end of the semicircular baffle 1 8 is preferably constructed to form a chamfered structure, and correspondingly, the bottom of the annular groove 7 is adapted to the chamfered structure. In this way, the friction generated when the two rotate and slide can be reduced.
