Rubber low-temperature brittleness tester

The utility model discloses a rubber low-temperature brittleness tester, which relates to the technical field of rubber low-temperature brittleness testers and comprises a machine body, an open slot is arranged on the upper end face of the machine body, an L-shaped support positioned on the rear side edge of the open slot is fixedly mounted on the upper end face of the machine body, and a moving structure and an impact structure are arranged on the L-shaped support. Through cooperation of the clamping block and the clamping piece, the T-shaped block and the clamp are fixedly connected, other parts do not need to be grabbed to fixedly connect the T-shaped block and the clamp, and then the possibility that the parts fall into cooling water in the opening groove in the installation process and are difficult to take out is reduced. 本实用新型公开了一种橡胶低温脆性测定仪，涉及橡胶低温脆性测定仪技术领域，包括机体，机体的上端面开设有开口槽，机体上端面固定安装有位于开口槽后侧边的L型支架，L型支架上设有移动结构和冲击结构,该橡胶低温脆性测定仪，通过卡块和卡件的配合，使得T型块和夹具固定连接，不需要再抓取其他零件使得T型块和夹具固定连接，进而减少了零件在安装过程中掉落至开口槽内部冷却水内难以取出的可
