Improve further again as of the present utility model, described working plate is also provided with protective cover.Carry out in process in test, operating personnel can be protected to preserve from.
Improve further as of the present utility model, described protective cover is connected with described working plate track again.A typical embodiment, before and after described working plate, side respectively arranges a guide rail, and described protective cover arranges corresponding slide block, by coordinating of slide block and guide rail, protective cover can be moved left and right on working plate.More preferably, be provided with limited block at described guide rail two ends, when protective cover moves to rail end, this limited block can prevent protective cover slippage.
Improve further again as of the present utility model, described protective cover is also provided with handle, conveniently can pull protective cover.
Improve further again as of the present utility model, bottom described frame, be also provided with adjustment lower margin.
Improve further again as of the present utility model, described frame is also provided with control panel.
Further improve as of the present utility model, described working plate is also provided with rotary disk limitation device.After test completes, rotating disk stops after returning back to starting point, prepares next test.
