Further, the workbench（20）The center of circle and supporting pad（21）Axis on same vertical plane, and the support Pad（21）Detachably.

Further, the workbench（20）On chute（22）On be additionally provided with and outer put thrust to fasten the pushing block of sample （24）.

Further, the clamping head（33）Rotatable conversion head, the obvolvent space size that its two ends head is formed It is different.

The beneficial effects of the utility model：

1st, the utility model can be targetedly complicated for some and easily slides the part for coming off in measurement and carry out Measurement, improves the occasion for using.

2nd, the setting of supporting pad, can be supported to axle class sample more long.

3rd, workbench is provided with chute, targetedly can be fixed locking to size specification sample, and its clamping head can Shift one's position to realize locking by part dimension.

Specific embodiment

In order that those skilled in the art more fully understand the technical solution of the utility model, below in conjunction with the accompanying drawings to this reality Be described in detail with new, the description of this part be only it is exemplary and explanatory, should not be to protection domain of the present utility model There is any restriction effect.

As Figure 1-Figure 4, concrete structure of the present utility model is：One kind clamps dress for Rockwell apparatus sample support Put, it includes body 1, the body 1 includes being assemblied in indicator 10 on body 1, pressure head 11, becomes hand-off 12, relief lever 13rd, loading handle 14, handwheel 15 and support meanss 2；The support meanss 2 include workbench 20 and supporting pad 21, the work The bottom of platform 20 sets and is connected in the threaded rod of the control lifting of handwheel 15, and top sets and connects hold assembly 3, is provided with its arc-shaped surface Several chutes 22, and home position is provided with the circular groove 23 for supporting spherical sample；The hold assembly 3 is included in The mobile sliding block 31 for adjusting orientation is provided with chute 22, support cylinder 32, connecting rod is connected with turn in the one end of sliding block 31 36 and the clamping head 33 being linked on connecting rod 36, the packing ring 34, the nut 35 that screw up on the screw thread of connecting rod 36.
