[0019] Through the above-described configuration, the limiting tube 41 limits the lifting and lowering of the test rod 31, preventing lateral displacement of the test rod 31 during operation and thus affecting test accuracy. The limiting box 42 provides limiting and protection for the test object, preventing it from splashing and improving operational safety. The positioning plate 52, in conjunction with the inner wall of the limiting box 42, further stabilizes the position of the test object, improving operational safety and test accuracy.

[0020] In this embodiment of the top pressure strength tester, a connecting pipe 422 is fixedly installed on the upper part of the limiting box 42, and the connecting pipe 422 is threadedly fixedly connected to the lower part of the limiting pipe 41. This arrangement facilitates the connection between the limiting box 42 and the limiting pipe 41.

[0021] In this embodiment of the top pressure strength tester, a mounting plate 423 is fixedly installed at the lower part of the limiting box 42, and the mounting plate 423 is fixedly installed on the base plate 1 by bolts. The upper surface of the mounting plate 423 is flush with the upper surface of the base plate 1. This improves the installation stability of the limiting box 42. Optionally, a strip-shaped slot is provided on the base plate 1 for the bolts to pass through, which facilitates the adjustment of the installation position of the mounting plate 423.

[0022] In this embodiment of the top pressure strength tester, the driver 51 is a cylinder, and the cylinder shaft 511 is fixedly connected to the positioning plate 52. This configuration results in a simple structure and stable operation.

[0023] In this embodiment of the top pressure strength tester, a protective plate 6 is slidably sleeved on the cylinder shaft 511. The size of the protective plate 6 is larger than the size of the pick-up and put-out port 421. The protective plate 6 is used to cover the pick-up and put-out port 421. A limiting step 512 is fixedly installed on the side wall of the cylinder shaft 511. The protective plate 6 is located between the limiting step 512 and the positioning plate 52. A return spring 61 is sleeved on the cylinder shaft 511. One end of the return spring 61 abuts against the limiting step 512, and the other end of the return spring 61 abuts against the protective plate 6. With this configuration, after the positioning plate 52 extends into the limiting box 42, the protective plate 6 covers the pick-up and put-out port 421. The structure is simple and prevents the test item and its parts from splashing out of the pick-up and put-out port 421, thus improving operational safety.

A locking screw 11 is threaded onto the base plate 1, and the locking screw 11 is used to press against the mounting ring plate 7 to lock it in place. This arrangement facilitates the adjustment of the position of the driver 51 on the base plate 1, thereby adapting to the position of the pick-up and drop-out port 421 on the limit box 42. The use of the locking screw 11 to lock the mounting ring plate 7 results in a simple structure and stable installation.

[0026] Optionally, a through-hole annular limiting opening is provided on the base plate 1, and the mounting ring plate 7 is rotatably disposed in the annular limiting opening. An annular cover plate 71 is detachably and fixedly disposed on the bottom of the base plate 1 to cover the lower part of the annular limiting opening. In this configuration, the annular cover plate 71 limits the mounting ring plate 7, preventing it from falling off and facilitating the installation and removal of the mounting ring plate 7 from the lower part of the annular limiting opening.
