However, the grasping mechanism is installed and fixed, which makes it difficult to disassemble, resulting in inconvenience in disinfection and cleaning. Technical problems.

[0027] Embodiment 2:

[0028] like Figure 1-4 As shown, on the basis of embodiment 1, the utility model provides a technical solution: an installation groove 10 and an active cavity 9 are respectively opened on the outer side of the support 7, a clamping groove 11 is opened between the active cavity 9 and the installation groove 10, a first clamping block 15 is fixedly installed on the bottom of the inner cavity of the clamping groove 11, and a positioning member 8 is slidably connected to the inner side of the clamping groove 11, a second clamping block 16 is fixedly installed on the bottom of the positioning member 8, the second clamping block 16 and the first clamping block 15 are both made of rubber material, an electric telescopic rod 14 is inlaid on the bottom of the inner cavity of the active cavity 9, and an active block 17 slidably connected to the active cavity 9 is fixedly connected to the output end of the electric telescopic rod 14, and the active block 17 is fixedly connected to the positioning member 8.
