Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
Example (b): road surface leveling device
As shown in fig. 1 to 5, a road leveling device has a specific structure including:
At least two scissor structures are arranged on the scissor arms 7. The arrangement of the plurality of scissor structures can ensure the outward extending distance of the scissor arms 7, and meet the requirements of users.
Top surface fixed mounting tray 9 of slider 6, one side that main part 1 was kept away from to tray 9 is equipped with breach 10, the top surface of tray 9 is equipped with several elastic bandage 11, all be equipped with laser range finder 12 in the tray 9, relative with tray 9 the periphery of montant 8 is fixed mounting locating plate 13 respectively, locating plate 13 sets up with corresponding laser range finder 12 respectively relatively. When the device is used, the scissor arms 7 extend outwards to drive the corresponding vertical rods 8 to move synchronously, the vertical rods 8 drive the positioning plates 13 connected with the vertical rods 8 to move synchronously, and a user can measure the positions of the positioning plates 13 through the laser range finders 12, so that the user can conveniently judge the moving distance of the positioning plates 13 and position the vertical rods 8; laser range finder 12 is fixed in corresponding tray 9 through corresponding elastic bandage 11 respectively in, the user still can take out laser range finder 12 in corresponding tray 9 and use, and the handheld laser range finder 12 of convenient to use person uses.
