[0028] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will make a detailed description of the specific embodiments of the present utility model in conjunction with the drawings of the specification.

[0029] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0030] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that mutually excludes other embodiments.

[0031] Example 1

[0032] Reference Figures 2 to 7 , which is the first embodiment of the present utility model. This embodiment provides a telescopic cantilever fixed bracket. The telescopic cantilever fixed bracket includes an adjustment assembly 200, a limit assembly 300, and a main body assembly 100. The cooperation of the three can save the time and effort of installation and disassembly, reduce thread wear, and improve the fixing stability and reliability.

[0033] Specifically, the adjustment assembly 200 includes an upper pressure plate 201a, a lower pressure plate 201b, a first spring 201c, an airbag 201d, and an exhaust valve 201e. The lower pressure plate 201b is arranged inside the upper pressure plate 201a. The first spring 201c is fixed to the top of the lower pressure plate 201b. The airbag 201d is arranged at the bottom of the upper pressure plate 201a. The exhaust valve 201e is located at the top of the upper pressure plate 201a and is connected to the airbag 201d.

[0034] When the lower pressure plate 201b moves downward, the spring 201c is deformed by the force. When the upper pressure plate 201a is placed on the table edge, release the lower pressure plate 201b. The restoring elastic force of the spring 201c will pull the lower pressure plate 201b back to pre-limit the table edge. Then, the subsequent parts will cooperate to complete the limiting work. The airbag 201d will prevent the clamping between the upper pressure plate 201a and the lower pressure plate 201b from loosening when the user adjusts the angle of the bracket. At this time, the airbag 201d will expand and fit with the tabletop to increase the resistance, further preventing the loosening situation. When the airbag 201d expands to a certain extent, it will push up the exhaust valve 201e to discharge the air, ensuring that the airbag 201d will not expand continuously.

[0035] Specifically, the limit assembly 300 is arranged on one side of the upper pressure plate 201a and includes a limit box 301a, a tension spring 301b, and a limit plate 301c. The tension spring 301b is arranged inside the limit box 301a. One end of the tension spring 301b is fixed to the bottom of the limit plate 301c, and the other end is arranged on the inner bottom wall of the limit box 301a.

[0036] When the pre-installation is completed, it will be locked through the cooperation of subsequent parts. At this time, the limit plate 301c will drive the tension spring 301b to move upward under the force. When the locking is completed, the restoring elastic force of the tension spring 301b will pull the limit plate 301c downward to limit it, and completely complete the installation work of the bracket body 101a.

[0037] Example 2

[0038] Reference Figures 2 to 7 , which is the second embodiment of the present utility model. This embodiment is based on the previous embodiment.

[0039] Specifically, an air intake valve 201f is provided at the top of the airbag 201d, and an extrusion block 201g is provided at the top of the air intake valve 201f.

[0040] The support body 101a is provided with a notch, and the extrusion block 201g is slidably connected to the notch. A groove is provided at the top of the upper pressure plate 201a, and the air intake valve 201f is slidably connected to the groove. When the extrusion block 201g moves downward, the air will be pushed downward. Due to the pressure of the air pressure, the air intake valve 201f will open at this time to inhale the air into the airbag 201d, thereby completing the expansion work of the airbag 201d.

[0041] Specifically, a second spring 201h is provided at the top of the extrusion block 201g. A push rod 201i is further provided on one side of the extrusion block 201g, and an air intake valve 201j is further provided on one side of the extrusion block 201g. The push rod 201i is movably connected to the extrusion block 201g.

[0042] The push rod 201i is fixed to the bottom of the adjusting rod 101b. When the adjusting rod 101b swings to one side, the push rod 201i will swing to one side together at this time. The push rod 201i will push the extrusion block 201g to move downward. At this time, the air intake valve 201j will block to prevent air from flowing out. At this time, the second spring 201h is deformed by force. When the adjusting rod 101b swings to the other side, the push rod 201i will also swing to the other side together. At this time, the extrusion block 201g that loses the force will be pulled back by the second spring 201h to reset, and the air intake valve 201j will open to supplement air at that time.

[0043] Specifically, one side of the extrusion block 201g is an inclined surface, and the inclined angle is 45 degrees, and one side of the push rod 201i is in contact with the inclined surface.

[0044] When the push rod 201i swings to one side, one side of the push rod 201i will come into contact with the inclined surface of the extrusion block 201g. When the push rod 201i continues to swing, one side of the push rod 201i will move along the inclined surface of the extrusion block 201g and push the extrusion block 201g to move downward to inflate the airbag 201d.

[0045] Specifically, a chute 201a-1 is provided at the bottom of the upper pressure plate 201a, and the lower pressure plate 201b is slidably connected to the chute 201a-1.

[0046] The lower pressing plate 201b and the spring 201c are both arranged in the sliding groove 201a-1. One end of the spring 201c is fixed to the inner top wall of the sliding groove 201a-1, and the other end is fixed to the top of the lower pressing plate 201b. The lower pressing plate 201b can slide in the sliding groove 201a-1 and can be clamped according to the thickness of the table edge to complete pre-installation. At this time, it can be checked whether it is installed in the appropriate position. If not, the lower pressing plate 201b can be pulled down to continue adjusting the position, avoiding the need to rotate the thread every time for installation and disassembly.

[0047] Specifically, a notch 201a-2 is opened on one side of the upper pressing plate 201a. A fixed pile 202a is fixed in the notch 201a-2. A handle 202b is arranged on one side of the fixed pile 202a, and the handle 202b is connected to the fixed pile 202a by a rotating shaft.

[0048] The handle 202b and the fixed pile 202a are connected by a bearing. After the pre-installation is completed, the handle 202b is flipped towards the limiting box 301a. At this time, one side of the handle 202b will contact the limiting plate 301c and push the limiting plate 301c to move upward. At this time, the tension spring 301b will be deformed by force. After the handle 202b is flipped to the final position, the tension spring 301b will drive the limiting plate 301c to move downward to limit the handle 202b.

[0049] Embodiment 3

[0050] Refer to Figure 1 , which is the third embodiment of the present utility model, and this embodiment is based on the first two embodiments.

[0051] Specifically, a groove 201b-1 is opened on one side of the lower pressing plate 201b. A pressing plate 203a is arranged on one side of the groove 201b-1, and the pressing plate 203a fits with the groove 201b-1.

[0052] While the handle 202b is being flipped, its surface will fit with the pressing plate 203a and push the pressing plate 203a to move inward. At this time, the pressing plate 203a and the groove 201b-1 will fit together to apply frictional force to the lower pressing plate 201b to prevent the lower pressing plate 201b from moving up and down.

[0053] Specifically, a plugging pile 203b is arranged on one side of the pressing plate 203a, and the plugging pile 203b is plugged into the fixed pile 202a.

[0054] After the plugging pile 203b is plugged into the fixed pile 202a, the plugging pile 203b will limit the fixed pile 202a to prevent the fixed pile 202a from moving up and down.

[0055] Specifically, one end of the limiting plate 301c is beveled, and the bevel angle is 45 degrees.

[0056] When the handle 202b is flipped towards the limit box 301a, one side of the handle 202b will come into contact with the inclined surface of the limit plate 301c, driving the limit plate 301c to move upward under force. At this time, the tension spring 301b is deformed by the force. When the handle 202b moves past the limit plate 301c, the restoring elastic force of the tension spring 301b will drive the limit plate 301c to move downward to limit the handle 202b.

[0057] Specifically, it further includes a main body assembly 100, which is arranged on the top of the upper pressing plate 201a and includes a bracket body 101a and an adjusting rod 101b. The adjusting rod 101b is arranged on the bracket body 101a, and the adjusting rod 101b and the bracket body 101a are connected by a rotating shaft.

[0058] The adjusting rod 101b and the bracket body 101a can be used to adjust the angle and then be used.

[0059] During use, the lower pressing plate 201b moves downward. At this time, the spring 201c is deformed by the force. After the upper pressing plate 201a is placed on the edge of the table, release the lower pressing plate 201b, and the restoring elastic force of the spring 201c will pull the lower pressing plate 201b back to pre-limit the edge of the table. After the pre-installation is completed, flip the handle 202b towards the limit box 301a. At this time, one side of the handle 202b will come into contact with the limit plate 301c and push the limit plate 301c to move upward. At this time, the tension spring 301b will be deformed by the force. While the handle 202b is being flipped, its surface will fit with the pressing plate 203a and push the pressing plate 203a to move inward. At this time, the pressing plate 203a will fit with the groove 201b-1 to apply frictional force to the lower pressing plate 201b to prevent the lower pressing plate 201b from moving up and down. After the handle 202b is flipped to the final position, the tension spring 301b will drive the limit plate 301c to move downward to limit the handle 202b. After the bracket body 101a is installed on the upper pressing plate 201a, the angle of the adjusting rod 101b can be adjusted and then be used.

[0060] When adjusting the angle using the adjusting rod 101b, the adjusting rod 101b swings to one side. At this time, it will drive the pushing rod 201i to swing to one side together. One side of the pushing rod 201i will move along the inclined surface of the pressing block 201g and push the pressing block 201g to move downward. At this time, the intake valve 201j will be blocked to prevent air from flowing out. Then, the second spring 201h deforms under force. Then, the downward movement of the pressing block 201g will push the air to move downward. Due to the pressure of the air pressure, at this time, the suction valve 201f will open to suck air into the airbag 201d. The airbag 201d will expand and fit the desktop to increase the resistance, further preventing loosening. When the airbag 201d expands to a certain extent, it will lift the exhaust valve 201e to discharge the air. When the adjusting rod 101b swings to the other side, the pushing rod 201i will also swing to the other side together. At this time, the pressing block 201g that loses force will be pulled back by the second spring 201h for reset. At that time, the intake valve 201j will open to supplement air.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
