At three angles of triangular supports platform.
Preferably, the diameter of the rack platform and boss centre bore is equal, diameter and the paddle type mill cloth of the centre bore
The outer diameter of family name's hardometer sleeve is identical.
Preferably, the fixing piece is the second bolt, and second bolt penetrates boss side surfaces threaded hole and is connected to boss
On side.
Preferably, the boss is cylindrical shape.
Preferably, it is axially seen along boss, second bolt is evenly distributed in boss side surfaces.
Preferably, the number of second bolt is no less than 2.
Preferably, the second all bolt is in same level height.
The beneficial effects of the utility model are：
(1) it is accurately positioned hardness determination point：By adjusting the second bolt, during hammering type Brinell hardness tester sleeve is fixed on
In heart hole, by adjusting the height of the first nut and the second nut, so that hammering type Brinell hardness tester sleeve bottom pressure head is located at and survey
Determine the hardness point position of part, magnetic chuck can be such that rack platform fixes, and hardness determination point does not move, to be accurately positioned
Hardness point.
(2) safety：The support handle of traditional hammering type Brinell hardness tester needs reviewer to be hammered into shape with holding is next
It hits, reviewer artificially shakes during hammering, testing staff is because fear causes hammering positions when hammering to shift, to make
Personal injury may occur for reviewer, and the utility model can be completed to fix without reviewer is hand steered, it is ensured that detection
The personal safety of personnel.
