Lid 9 is mutually permanently connected by welding, and the bevel pinion II axis 12 is together by a threaded connection with the special claw 14,
The special claw 14 and the circumferentially fixed frame 15 are by together with clearance fit, the circumferentially fixed frame 15 and the door
9 are mutually permanently connected by welding；The self-locking device 16 is placed between the shell 1 and the bevel pinion I5, it is described
The ratchet 166 of self-locking device 16 is mounted on the bevel pinion I axis 6 by spline, and the pedestal 161 of the self-locking device 16 is logical
It crosses screw to be fixedly connected with the shell 1, the adjusting screw rod 164 of the self-locking device 16 is connected with the shell 1 by screw thread
It connects；Make the shell 1, the cone fluted disc I supporter 2, the cone fluted disc I bearing 3, the cone fluted disc I4, the door 9 and institute
The axis of cone fluted disc II8 is stated on same straight line；The bevel pinion I5, the bevel pinion I axis 6, the bevel pinion I
Bearing 7, the bevel pinion II10, the bevel pinion II bearing 11, the bevel pinion II axis 12, the pedestal 13, institute
Stating special claw 14, the circumferentially fixed frame 15, the self-locking device 16 respectively has three sets, makes them around the same straight line
Equal part distribution.
When clamping test specimen, the adjusting screw rod 164 is screwed clockwise with hand, the adjusting screw rod 164 rotates on one side, on one side
It moves downward, the frustum cone side of the adjusting screw rod 164 pushes the pawl 165 to rotate, and then the pawl 165 and the spine
Wheel 166 cooperates, and rotate clockwise the bevel pinion I axis 6 can only, i.e., the described special claw 14 can only be to close to center
