Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1 - 3 In an embodiment of the present utility model, a tensile testing device for aluminum forgings includes a workbench 1, a movable rod 2 is vertically slidably mounted on the inner side of the workbench 1, a clamping block 3 for clamping the material is provided at the bottom of the movable rod 2, and an adjustment mechanism 4 is provided on the movable rod 2 and the clamping block 3;

[0030] The adjustment mechanism 4 includes a limiting unit and a guide unit;

[0031] The limiting unit is used to adjust the height of the clamping block 3;

[0032] The guide unit is used to provide guidance for the vertical movement of the clamping block 3;

[0033] The limiting unit includes a connecting rod 401, a vertical guide groove 402, a horizontal guide groove 403, a rotating block 406, and a limiting block 407;

[0034] The connecting rod 401 is fixed to the top of the clamping block 3 and extends to the inside of the movable rod 2. The connecting rod 401 is used to drive the clamping block 3 to move synchronously;

[0035] A vertical guide groove 402 is provided on the outer wall of the connecting rod 401 and is used to provide guidance for the vertical movement of the limit block 407;

[0036] The transverse guide groove 403 is formed on the outer wall of the connecting rod 401 and is used to provide a limit for the vertical movement of the limit block 407;

[0037] The rotating block 406 is rotatably sleeved on the bottom end of the movable rod 2 and surrounds the outer wall of the connecting rod 401. The rotating block 406 is used to drive the limiting block 407 to move synchronously;

[0038] The limit block 407 is fixed to the inner side of the rotating block 406 and extends into the vertical guiding groove 402. The limit block 407 is used to provide a limit for the vertical movement of the connecting rod 401.

[0039] The guiding unit includes a positioning block 404 and a positioning groove 405.

[0040] The positioning block 404 is fixed to the outer wall of the top end of the connecting rod 401. The positioning block 404 is used to provide a limiting guide for the vertical movement of the connecting rod 401.

[0041] The positioning groove 405 is formed in the inner wall of the movable rod 2. The positioning groove 405 is used to provide space for the movement of the positioning block 404.

[0042] In this embodiment: When it is necessary to clamp materials with longer or shorter lengths, by applying a rotational force to the rotating block 406, the stressed rotating block 406 will synchronously drive the limit block 407 to rotate, so that the limit block 407 rotates axially along the inner side of a transverse guiding groove 403 until the limit block 407 moves from the inside of the transverse guiding groove 403 to the vertical guiding groove 402, thereby releasing the limit between the limit block 407 and the connecting rod 401, facilitating the adjustment of the height of the connecting rod 401. According to the length of the material, pull or push the connecting rod 401 to move, so that the connecting rod 401 vertically moves along the inner side of the positioning groove 405 through the positioning block 404. At the same time, the limit block 407 will also vertically move along the inner side of the vertical guiding groove 402 to ensure that the clamping block 3 does not rotate until the clamping block 3 is adjusted to a required position. At this time, a reverse rotational thrust can be applied to the rotating block 406 to dock the limit block 407 with the end of a transverse guiding groove 403, so that the limit block 407 enters the end of a transverse guiding groove 403 again, completing the vertical movement limit of the connecting rod 401. At this time, the material can be clamped by the clamping block 3, achieving the purpose of fine-tuning the distance between the clamping blocks 3, increasing the adjustment range, and improving the working efficiency.

[0043] Please refer specifically to Figures 1 - 3 , the inner side of the positioning groove 405 matches the outer wall of the positioning block 404. The positioning block 404 and the positioning groove 405 are symmetrically distributed on the outer walls of the movable rod 2 and the connecting rod 401. The number of transverse guiding grooves 403 is set to be multiple, and the multiple transverse guiding grooves 403 are evenly distributed on the outer wall of the connecting rod 401. One end of the transverse guiding groove 403 is communicated with the vertical guiding groove 402. The inner sides of the transverse guiding groove 403 and the vertical guiding groove 402 match the outer wall of the limit block 407. A sliding groove for the vertical movement of the connecting rod 401 is formed on the inner side of the movable rod 2.

[0044] In this embodiment: Through this structure, when the connecting rod 401 is pulled by an external force, it can synchronously drive the positioning block 404 to move vertically, so that the positioning block 404 moves vertically along the inner side of the positioning groove 405 and the limiting block 407 moves vertically along the inner side of the vertical guiding groove 402 synchronously, so that the connecting rod 401 always moves vertically without rotating.
