This testing machine is widely used in aerospace, automotive, electronics and other fields, and can effectively evaluate the mechanical properties and durability of materials under extreme temperature conditions.

[0003] When a high-precision high-temperature testing machine is in use, the tested object is limited by the upper and lower clamps. However, the upper clamp and the connecting column are connected by a threaded structure. This connection structure will reduce the firmness between the upper clamp and the connecting column. Therefore, the market needs a new device to solve the current problem. Utility Model Content

[0014] Compared with the existing technology, the present invention provides a high-precision high-temperature testing machine with an internal limit structure, which has the following beneficial effects:

[0015] 1. When installing the upper clamp and the connecting column of this device, pressing the button compresses the stainless steel spring. At the same time, pressing the button pushes the connecting rod to move, and the connecting rod causes the fixing block to enter the internal position of the connecting column. The fixed cylinder B fixed at the upper end position of the upper clamp is inserted into the internal position of the fixed cylinder A. At the same time, the connecting column is inserted into the internal position of the fixed cylinder B. At this time, when the fixed cylinder B enters the internal position of the fixed cylinder A, the connecting rod moves along the slide groove to the internal position of the card slot. Releasing the button releases the elastic force of the stainless steel spring and clamps the fixing block in the card slot. At this time, the fixing block is simultaneously clamped at the internal positions of the fixed cylinder A, the fixed cylinder B and the connecting column. This connection method can increase the firmness between the connecting column and the upper clamp.

[0016] 2. The traditional ventilation mesh is installed with the main body by bolts.
