Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 The present invention provides an embodiment of a fastener for easy adjustment of the docking height, comprising a support device 3, a displacement device 2 slidably sleeved on the outer ring of the support device 3, a limiting device 1 slidably inserted at both ends of the top of the displacement device 2, and a screw 4 slidably inserted between the limiting device 1 and the displacement device 2. The displacement device 2 includes a positioning bolt 7, a locking key 8, an extension bracket 9, a support base plate 10, a pointer 11, and a rear plate 12. The locking key 8 is symmetrically fixedly installed at the front end of the rear plate 12. The locking key 8 and the pointer 11 are fixedly installed at opposite ends of the extension bracket 9, with the pointer 11 located in front of the locking key 8. The support base plate 10 is fixedly installed at the end of the extension bracket 9 away from the locking key 8. The positioning bolt 7 is threadedly inserted into the center of the rear end of the rear plate 12.

[0021] The limiting device 1 includes a limiting plate 5 and a movable rod 6. The movable rod 6 is symmetrically fixedly installed at the bottom end of the limiting plate 5, so that the movable rod 6 can be inserted into the top of the supporting base plate 10.

[0022] The support device 3 includes a side support plate 13, a central base plate 14, and an anti-slip pad 15. The side support plate 13 is fixedly installed on both sides of the central base plate 14, and the central base plate 14 is fixedly installed on the top of the anti-slip pad 15, which can support the temporary placement of the central base plate 14.

[0023] The key 8 is slidably inserted into the inside of the side support plate 13, and the movable rod 6 is slidably inserted into the top of the support base plate 10, so that the limiting plate 5 can contact the support base plate 10.

[0024] Both the top center of the support base plate 10 and the bottom center of the limiting plate 5 are provided with arc grooves. The limiting plate 5 is made of magnet, which makes it easy to install the limiting plate 5 on the top of the support base plate 10.

[0025] The top of the support base plate 10 is symmetrically provided with round holes, the front surface of the central base plate 14 is marked with scale lines, and the side support plate 13 is provided with a slot at the center of the side end opposite to the central base plate 14 to ensure that the extension bracket 9 moves up and down in a straight line.

[0026] Working principle: In use, first move the central base plate 14 to the designated position, and let the anti-slip pad 15 contact the ground so that the device can be temporarily placed. Then, the limiting plate 5 can be moved upward and pulled until the limiting plate 5 is disengaged from the supporting base plate 10. Then, move the screw 4 into the arc groove at the center of the top of the supporting base plate 10. Then, move the limiting plate 5 to the top of the supporting base plate 10 again. Through the adsorption and adhesion between the limiting plate 5 and the supporting base plate 10, the screw 4 can be restricted between the limiting plate 5 and the supporting base plate 10. Between the base plates 10, and simultaneously, when the limiting plate 5 is adapted to the supporting base plate 10, the movable rod 6 is slidably inserted into the round hole inside the top of the supporting base plate 10, so that the limiting plate 5 can be placed on the top of the supporting base plate 10. Subsequently, after the two screws 4 are in place, the extension bracket 9 can be lifted upward, so that the screws 4 can be moved upward synchronously. When the extension bracket 9 is moved, the pointer 11 can be moved on the scale line on the front surface of the central base plate 14, so that the user can accurately control the extension bracket. The displacement of the bracket 9 is controlled by the key 8 sliding in the slot inside the side support plate 13 away from the central base plate 14, ensuring that the extension bracket 9 moves in a straight line and preventing the extension bracket 9 from tilting during displacement. Then, when the screw 4 moves to the specified height, the positioning bolt 7 can be turned to tighten with the rear end of the central base plate 14, so that the extension bracket 9 can be temporarily restricted to the specified height. Then, the user can operate the tool to turn the screw 4 so that the screw 4 can be installed at the specified height. At the same time, when the screw 4 is not fully turned to the limit position, the limiting plate 5 can be pulled upward so that the limiting plate 5 can be disengaged from the support base plate 10. Then, the positioning bolt 7 is turned in the opposite direction so that the positioning bolt 7 can be disengaged from the central base plate 14. At this time, the extension bracket 9 will slide downward and fall, causing the support base plate 10 to disengage from the screw 4. Then, the entire device can be removed, and external tools can be used to fully turn the screw 4 to the limit position to complete the work of installing the screw 4 to the specified height.

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