DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-4The utility model provides an embodiment: a locking member that is convenient to install and combine, including a supporting device 3, displacement devices 2 are symmetrically slidably inserted on both sides of the supporting device 3, and a positioning device 1 is fixedly installed on the side end of the displacement device 2. The positioning device 1 includes a guide rod 4, a synchronization rod 5, a support back plate 6, a support cavity 7, a positioning rod 8 and a reset spring 9. The positioning rod 8 is slidably inserted in one end inside the support cavity 7, the support back plate 6 is fixedly installed at the other end inside the support cavity 7, the reset spring 9 is fixedly installed between the support back plate 6 and the positioning rod 8, the guide rod 4 slides through the support back plate 6 and is connected with the positioning rod 8, and the synchronization rod 5 is fixedly installed between the four guide rods 4.

[0021] The displacement device 2 includes a support base 10, a displacement key 11, a limit plate 12 and a positioning bolt 13. The displacement key 11 is fixedly installed at the bottom of the side end of the support base 10, and the positioning bolt 13 is threadedly inserted into the top end of the support base 10 close to the displacement key 11. The limit plate 12 is slidably inserted into the side end of the support base 10 close to the displacement key 11, and is rotatably connected to the top end of the limit plate 12 through the bottom end of the positioning bolt 13, so that when the positioning bolt 13 rotates, it can drive the limit plate 12 to move up and down.

[0022] The supporting device 3 includes a supporting table 14, positioning feet 15 and guide grooves 16. The guide grooves 16 are arranged at the centers of both sides of the supporting table 14. The positioning feet 15 are fixedly installed at both ends of the bottom of the supporting table 14 to support the supporting table 14 for operation.

[0023] The displacement sliding key 11 is slidably inserted in the guide groove 16 , and the support cavity 7 is symmetrically fixedly installed on both sides of the support base 10 , so that the limiting work can be performed on both sides of the support base 10 .

[0024] The interior of the support cavity 7 is arranged in a hollow state, so that the positioning rod 8 can be easily moved into the interior of the support cavity 7 .

[0025] Round holes are equidistantly provided at both ends of the support table 14 to facilitate the positioning of the positioning rod 8 and the round holes.

[0026] Working principle: when in use, the workpiece that needs to be fixed by the outside world can be placed on the top of the supporting table 14, and then the positioning bolt 13 can be screwed. A key is fixedly installed through the side end of the limit plate 12 close to the supporting base 10, and a slot is opened inside the side end of the supporting base 10 close to the positioning bolt 13. The bottom end of the positioning bolt 13 is rotatably connected with the top end of the limit plate 12, so that when the positioning bolt 13 is screwed, the limit plate 12 can be driven to move downward in a straight line, so that the limit plate 12 can squeeze the workpiece to dock with the supporting table 14. Subsequently, when the position of the limit plate 12 needs to be adjusted, the synchronization rod 5 can be pulled outward, so that the positioning rod 8 can be driven by the guide rod 4 to enter the interior of the supporting cavity 7, so that the positioning rod 8 can be moved out of the circular holes on both sides of the supporting table 14, releasing the supporting base 10. At this time, the supporting base 10 can be moved as a whole, so that the limit plate 12 can be moved to the designated workpiece. The work area, then, the displacement sliding key 11 slides inside the guide groove 16, so that the support base 10 can be guaranteed to move in a straight line. When the limit plate 12 moves to the specified working area, it can drive the positioning rod 8 to be vertically aligned with the circular hole in the corresponding area. At this time, the synchronization rod 5 can be released, and the elasticity of the reset spring 9 will drive the positioning rod 8 to quickly reset until the positioning rod 8 is inserted into the circular holes on both sides of the support table 14, so that the support base 10 can be limited and positioned to prevent the support base 10 from sliding again when the limit plate 12 is working. When the device is in use, when it is necessary to disassemble the support base 10, the above operation can be repeated to remove the positioning rod 8 from the circular hole inside the side end of the support table 14, and then the support base 10 is pulled until the displacement sliding key 11 is completely removed from the inside of the guide groove 16, so that the support base 10 can be disassembled from the inside of the support table 14 to complete the work.

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