2: the work of motor 16 drives transmission shaft 17 to start turning, so that the rotate gear 18 for being engaged with connection is driven to rotate, from
And connection gear 12 is driven to rotate, so that the first bevel gear 45 of 14 right end of driven shaft 14 and driven shaft is driven to rotate, first
The rotation of bevel gear 45 drives the second bevel gear 46 for being engaged with connection to rotate, thus before driving rotation axis 47 and rotation axis 47
The rotation gear 48 at end rotates, so that the gripping block 60 for being engaged with connection be driven to decline；
3: during gripping block 60 declines, chain 40 is slowly tensed, so that sliding shoe 69 be pulled to transport to the right in shaft 23
Dynamic, balladeur train 67 is to engage connection with rotate gear 18, to drive the rotation of balladeur train 67, thus drive shaft 23 with
And the bull wheel 24 of 23 right end of shaft rotates, the rope made of hemp 25 loses the pulling force of the rope made of hemp 25 in self gravity to relaxation, impact bar 57
Under move downward, block 54 lose impact bar 57 be extruded in elastomeric spring 55 act under move downward, drawstring 21 relaxation, it is trapezoidal
Block 22 pops up downwards under the effect of extension spring 20, prevents balladeur train 67 from resetting under the effect of connecting spring 66, works as gripping block
60 when moving downward, mandril 50 and 30 upper end face contact of metal material, to push mandril 50 to move upwards, to push rotation
Plate 70 is rotated up, and push plate 61 is then rotated the promotion of plate 70 and moves right, and contacts 73 right end of rotor plate with 57 left end of impact bar,
Under the effect of triangular groove 75, impact bar 57 can only move downward in impact chamber 41, to prevent impact bar 57 from moving downward shock
Metal material 30 rebounds upwards；
4: when gripping block 60 contradicts 30 upper surface of metal material, metal material 30 is fixed by gripping block 60, closes motor
16, impact bar 57 hits 30 upper surface of metal material, leaves hole, 57 opposite gripping blocks 60 of impact bar in 30 upper surface of metal material
It moves downward and is equal to the deep distance in hole, 59 left end of pointer refers in the corresponding graduation position of graduation apparatus 58；
5: when gripping block 60 is pressed downward metal material 30, the support plate 31 and push rod 34 of 30 lower end of metal material are squeezed and press to
Lower movement contacts so that mobile power source 36 be pushed to move downward with conducting block 39, and display 29 is started to work at this time, and record is hit
The scale of generation；
6: after the completion of test, starting motor 16 is inverted, so that second bevel gear 46 and balladeur train 67 is driven to invert, gripping block 60
It begins to ramp up, the rope made of hemp 25 starts to be tightened up, and mandril 50 loses extruding, and push plate 61 is transported to the left under the effect of both threads spring 71
Dynamic, impact bar 57 is pulled by the rope made of hemp 25 to be risen, and when 57 upper surface of impact bar squeezes block 54 again, drawstring 21 is tightened up, ladder
Shape block 22 moves upwards, and rotation axis 47 loses to be blocked in move downward under connecting spring 66 acts on and nibble with the disengaging of rotate gear 18
It closes, mobile power source 36, which loses push rod 34 and is extruded under contraction spring 38 acts on, to be moved right and disengage with conducting block 39, is shown
Device 29 stops working.
