Shelving and be provided with rotatable angle scale, the first original screen panel is arranged on angle scale and is rotated by angle scale.By pushing away
Enter the setting of device, make installing rack drive the first original screen panel to carry out level slip, make the first original screen panel and the position of the second original screen panel
Coordinate, it is simple to the display of experimental result, increase the service life of experimental provision.
As preferably, propeller includes expansion link and fixing pipe, and fixing pipe is fixed on the first sliding seat, sets in fixing pipe
Having female thread, expansion link to be provided with the external screw thread with screw-internal thread fit, expansion link contacts with installing rack and promotes installing rack to move.
By external screw thread and the cooperation of female thread, rotary extension post, it is achieved the horizontal displacement of telescopic mast, reach to promote the mesh of installing rack
's.
As preferably, expansion link is provided with scale.By the setting of scale, the clear and definite installing rack of user is facilitated to move horizontally
Distance.
As preferably, the first sliding seat is provided with chute, and installing rack is provided with the slide block coordinated with chute.Chute and slide block
Setting, make installing rack can along chute direction slide, it is to avoid the skew of installing rack.
As preferably, the second sliding seat being provided with installing plate, the second original screen panel is fixing on a mounting board, and installing plate is pacified
Equipped with multiple regulation screws and by the axial dipole field angle of regulation screw regulation peace the second original screen panel.Adjustable by regulation screw
Save the axial angle of the second original screen panel, make the axis of the second original screen panel and the axis of the first original screen panel be arranged in parallel, make experiment number
According to the most reliable.
This utility model, owing to have employed above technical scheme, has significant technique effect: by angle of rake setting,
The level making the first original screen panel carry out being perpendicular to guide rail direction is slided, and makes the position of the first original screen panel and the second original screen panel join
Close；By regulating the axial angle of screw scalable the second original screen panel, make axis and the axle of the first original screen panel of the second original screen panel
Line be arranged in parallel, makes experimental data more preferably reliable, increases the service life of experimental provision.
