[0009] By adopting the above technical solution, the cooperation between the dovetail groove and the dovetail block makes the structure more stable. When the pressure testing machine performs a downward pressing operation, the first fixing member and the second fixing member will not be separated from the base, further improving the stability of the structure.

[0010] The utility model is further configured that: the base is provided with an inserting groove at a position corresponding to the positioning core, and the inserting groove is inserted into the positioning core.

[0011] By adopting the above technical solution, the positioning core and the plug-in slot are matched and disassembled, and positioning cores of different sizes can be replaced to match the size of the handle required for positioning, thereby making the structure between the two more compact and stable, and facilitating installation and processing.

[0012] The utility model is further configured as follows: the base is connected to the plug-in slot, a hook slot is provided at the bottom of the base near the plug-in slot, and a limit block matched with the hook slot is provided at one side of the bottom of the positioning core.

[0013] By adopting the above technical solution, the hook groove and the limit block are arranged to limit the installation position of the positioning core, and the base is arranged to be connected with the plug-in groove. When the positioning core is assembled, the positioning core is inserted along the bottom of the plug-in groove.
