Embodiment

Relevant detailed description of the present utility model and technology contents, conjunction with figs. is carried out following explanation, however accompanying drawing only provides reference and explanation usefulness, is not to be used for the utility model is limited.

Fig. 2 is a combination schematic diagram of the present utility model, and Fig. 3 is a sectional perspective enlargement decomposition of the present utility model, and Fig. 4 is the combination schematic diagram of Fig. 3, and Fig. 5 is a local assembled sectional view of the present utility model.The utility model provides a kind of crystal chip bearing fixture, and it mainly comprises annular framework 10 and a pair of fixed mechanism 20, wherein:

Annular framework 10 can be made by aluminium or other material, and framework 10 is rounded.Extend internally in the bottom surface of framework 10 and to be formed with annular inward flange face 11, on the lateral of inward flange face 11, be extended with

inclined plane

12,12 end is extended with the end face 13 parallel with inward flange face 11 on the inclined plane, and on end face 13, equidistantly offer three screws 14, be respectively equipped with shrinkage pool 15 in the left and right sides of each screw 14.

Fixed mechanism 20 can be a pair or more of configuration, is three groups in the present embodiment, and it comprises fixation kit 21, fastening piece 22 and magnet assembly 23, and fixation kit 21 can be screw, and in like manner it also can be various kenels such as circular shaft, rivet.The below of described screw is provided with open slot 211, and its spiral shell is connected in the screw 14 that is connected to framework 10.Fastening piece 22 can be magnetic or is made by metal sheet, offers groove 221 and is formed with pivot 222 at an end of plate, and the other end then roughly is formed with down the button portion 223 of " U " shape.Pivot 222 can embed in the open slot 211 of fixation kit 21, and can swing up and down with respect to fixation kit 21.Magnet assembly 23 can be permanent magnet or is made by other material with magnetic adsorptive power, and the magnet assembly 23 of present embodiment is cylinder, and corresponds respectively to the position of each fastening piece 22 and be installed with in the shrinkage pool 15 that is fixed on framework 10.
