In the figure: 1. a support; 2. a housing; 3. testing the instrument; 4. sealing the sheet; 5. a clamping cylinder; 6. an L-shaped limiting eave; 7. a position clamping hole; 8. a clamping strip; 9. a bump; 10. a bit block; 11. a limiting hole; 12. a limit stop block; 13. and sealing the frame.

Detailed Description

Example 1:

as shown in figure 1, test instrument fastener with cell-phone cooperation use, including support 1 and the casing that is fixed with test instrument 3, support 1 one side is connected with the cell-phone, and support 1 another side is connected with casing 2, sets up the screens mechanism and the stop gear that match between support 1 and the casing 2.

As shown in fig. 2-3, the clamping mechanism includes a clamping cylinder 5 arranged on the support 1 and a clamping hole 7 arranged on the housing 2, a pair of clamping strips 8 arranged in parallel is arranged in the middle of the clamping hole 7, one end of each clamping strip 8 is fixed on the bottom surface of the clamping hole 7, the other end of each clamping strip is suspended, a bump 9 is arranged at the free end of each clamping strip 8, the top of each clamping hole 7 corresponds to the clamping cylinder 5 to form two clamping blocks 10, the limiting mechanism includes an L-shaped limiting eave 6 arranged at the edge of the support 1 and a limiting hole 11 arranged on the housing 2 and matched with the L-shaped limiting eave 6, the top of each limiting hole 11 corresponds to the L-shaped limiting eave 6 to form a limiting block 12, and the sum of the length value of the limiting block 12 and the width value of the L-shaped limiting eave 6 is smaller than the length value.
