Detailed Description
The utility model will be further described with reference to the accompanying drawings, without limiting the scope of the utility model to the following:
as shown in fig. 2-5, a detect frock convenient to detect saw bit hardness, it is including setting firmly the piece 10 of hugging closely on rockwell hardness appearance threaded rod 7, all set firmly support 11 on the terminal surface around the piece 10 of hugging closely, two supports 11 all set up in the right side of threaded rod 7, platform 12 has set firmly between two supports 11, platform 12 level sets up, platform 12's left end portion has set firmly cushion 13, cushion 13's width is less than the diameter of rockwell hardness appearance supporting seat 9, cushion 13's the top surface and platform 12's the top surface parallel and level, cushion 13's basal surface supports on rockwell hardness appearance supporting seat 9's top surface. Embrace and tightly to have seted up centre bore 14 in the piece 10, embrace and seted up breach 15 on the lateral wall of piece 10 tightly, breach 15 and centre bore 14 intercommunication, set up the through-hole 16 that runs through breach 15 on embracing the preceding terminal surface of piece 10 tightly, embrace piece 10 tightly on threaded rod 7 is located to centre bore 14 cover, wear to be equipped with screw 17 in the through-hole 16, threaded connection has nut 18 on the screw thread section of screw 17, and nut 18 supports to press in embracing tightly on piece 10, and under the threaded connection power, embrace piece 10 tightly on threaded rod 7.
