DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] See also Figures 1 to 4 The utility model provides a technical solution: an adjustable clamp, including a base 100, a lifting groove 200 is opened inside the base 100, a hydraulic support seat 300 is arranged inside the lifting groove 200, and the top of the hydraulic support seat 300 is fixedly connected with a bottom plate 400. By starting the hydraulic support seat 300, the bottom plate 400 can be driven to move up and down inside the lifting groove 200. The tops of the two ends of the bottom plate 400 are respectively connected with side plates A500 and side plates B600. The lifting and moving of the bottom plate 400 can drive the side plates A500 and side plates B600 to move up and down, thereby playing a role in height adjustment. The bottom end of the side plate A500 is fixed to the bottom plate 400, and the bottom end of the side plate B600 is slidably connected to the bottom plate 400, so that the side plate B600 can move left and right, so that The side panel A500 and the side panel B600 extend out of the lifting slot 200 at their top ends. A driving assembly 700 is connected to one side of the side panel B600. The driving assembly 700 can drive the side panel B600 to move left and right, thereby providing a clamping force for the fixture. The driving assembly 700 includes a threaded rod 701, a connecting seat 702, a through groove 703, a movable connecting groove 704 and a ball 705. A threaded seat threadedly connected to the threaded rod 701 is fixed on the top of the base 100. One end of the threaded rod 701 is movably connected to the side panel B600. By rotating the threaded rod 701, the side panel B600 can be pushed to move left and right. The top surface of the lifting slot 200 is located on one side of the side panel B600 and is provided with a top groove 800, which provides a moving space for the left and right movement of the side panel B600.

[0022] In this embodiment, preferably, a button is provided on a surface of one side of the base 100 close to the side panel A500, and the button is connected to the hydraulic support seat 300 through an electric wire, and the hydraulic support seat 300 can be started by pressing the button.

[0023] In this embodiment, preferably, a slide rail is provided on the top surface of the bottom plate 400, and a slide seat slidably connected to the slide rail is provided at the bottom end of the side plate B600 to achieve a sliding connection between the side plate B600 and the bottom plate 400.

[0024] In this embodiment, preferably, the connecting seat 702 is rotatably connected to one end of the threaded rod 701. This design can prevent the connecting seat 702 from rotating with the threaded rod 701. The through groove 703 is opened on the surface of the side plate B600, and the movable connecting groove 704 is opened inside the through groove 703. The through groove 703 and the movable connecting groove 704 are both longitudinally arranged long strip structures. The connecting seat 702 passes through the through groove 703 and extends into the inside of the movable connecting groove 704, and the side plate B600 and the threaded rod 701 are movably connected. The connecting seat 702 is connected to the through groove 703 and the movable connecting groove 704 is connected for lifting and sliding. The connecting seat 702 is a T-shaped structure when viewed from above. The connecting seat 702 is adapted to the inner walls of the through groove 703 and the movable connecting groove 704, which can prevent the connecting seat 702 from falling off from the through groove 703. By rotating the threaded rod 701, the connecting seat 702 can be pushed, and then the side panel B600 can be pushed, thereby realizing the left and right movement of the side panel B600. When the side panel B600 is lifted and moved, the connecting seat 702 can be lifted and slid inside the through groove 703 and the movable connecting groove 704, and will not interfere with the lifting and moving of the side panel B600.

[0025] In this embodiment, preferably, the ball 705 is arranged on one side of the connecting seat 702 and is in rolling contact with the inner wall of the movable connecting groove 704 to improve the smoothness of the connecting seat 702 in the through groove 703 and the movable connecting groove 704.

[0026] In this embodiment, preferably, a telescopic plate assembly 900 is provided between the top groove 800 and the side plate B600. The telescopic plate assembly 900 can adapt to the left and right movement of the side plate B600 and play a supporting role for the parts. The telescopic plate assembly 900 includes a receiving groove A901, a top plate A902, a receiving groove B903 and a top plate B904. The receiving groove A901 is provided on the inner wall of one side of the top groove 800, the top plate A902 is telescopically connected inside the receiving groove A901, the receiving groove B903 is provided inside the top plate A902, and the top plate B904 is telescopically connected inside the receiving groove B903. When clamping the parts, they can be placed on the top plate A902 and the top plate B904 first. When the side panel B600 moves, the top panel B904 and the top panel A902 can shrink inside the accommodating groove B903 and the accommodating groove A901 respectively, and will not hinder the movement of the side panel B600. The telescopic plate assembly 900 also includes a spring A905 and a spring B906. The spring A905 is connected between the inner wall of the accommodating groove A901 and the top panel A902, and the spring B906 is connected between the inner wall of the top panel A902 and the top panel B904. The outer end of the top panel B904 is against one side of the side panel B600. The design of the spring A905 and the spring B906 can provide a reset rebound force for the top panel A902 and the top panel B904, so that one end of the top panel B904 can always be close to the side panel B600.

[0027] Although the embodiments of the present invention have been shown and described (see the detailed description above for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
