The through holes 7 and the screw holes 11 on the opposite side are on the same horizontal planes, which is convenient for a screwdriver to pass through the first top support body 8 to fasten screws that pass through the screw holes 11 on the opposite side.

Embodiment 3

As shown in FIG. 9 to FIG. 16 , a difference from Embodiment 1 is that: on the basis of Embodiment 1, an adjustable top support component is installed on the top of the upper support body 3. The adjustable top support component includes a second top support body 9, the bottom of one end of the second top support body 9 in the horizontal direction is fixedly connected to the upper end of the upper support body 3. A tabletop support assembling body 10 is movably installed on the same end of the second top support body 9 connected to the upper support body 3, and the tabletop support assembling body 10 is fitted to the second top support body 9 or overlays the first top support body 9.
It should be noted that the second top support body 9 and the end of the tabletop support assembling body 10 may be connected by hinges or bolts and nuts to realize that the two can be rotated and adjusted on upper and lower horizontal planes, and the connecting manner is not limited to the two ways of connection mentioned above.
A first adjusting component is fixedly installed in the tabletop support assembling body 10, and the first adjusting component includes a flange 13 installed in the tabletop support assembling body 10 and an adjusting bolt 14 that passes through a bottom screw hole of the second top support body 9 and is connected to the flange. A gasket 15 is installed between the adjusting bolt 14 and the bottom of the second top support body 9.
It should be noted here that the gasket 15 is arc-shaped. When the tabletop support assembling body is tilted at different angles, the adjusting bolt will also be tilted to avoid too early damage of the adjusting bolt due to a lateral force.
Screw holes 11 are formed on an end of the tabletop support assembling body 10 in contact with the tabletop, for fixed connection with the tabletop by screws.
A set of reinforcement bolts 17 are symmetrically installed on the two side walls of the tabletop support assembling body 10 to enhance the stability of the tabletop support assembling body and reduce left-right swaying thereof.
A second adjusting component is fixedly installed in the second top support body 9. The second adjusting component includes a flange 13 installed in the top support body 9, an adjusting bolt 14 that passes through the flange and is connected to the flange, and a dome nut 16 installed in the tabletop support assembling body 10. The top of the adjusting bolt is in contact with the dome nut, and the tabletop support assembling body is adjusted by pushing the dome nut upward by the adjusting bolt.
An extension plate 12 is installed at one end of the tabletop support assembling body 10 away from the upper support body. A ring-shaped third chute 18 is formed on the extension plate 12 in the middle. Bolts pass through the third chute on the extension plate to be fixedly connected to threaded holes on the tabletop support assembling body 10, so as to realize the sliding adjustment in the horizontal direction, thus meeting the support requirements of tabletops with different depths. Gaskets are installed between the extension plate 12 and the bolts; and the upper end of the extension plate is provided with screw holes for connection with the tabletop.
A gasket is installed on one end of the extension plate 12 away from the tabletop support assembling body, so that the extension plate can be maintained at the same height with the tabletop support assembling body when it contacts with the tabletop.

Embodiment 4

A difference from Embodiment 3 is that in Embodiment 3, the bottom support body 2 and the upper support body 3 are of a hollow column structure, while in this embodiment, as shown in FIG. 17 to FIG. 19 , the bottom support body 2 and the upper support body 3 are of a side wall column structure. The side wall of the bottom support body 2 is provided with second bolt holes 24, and the upper support body 3 is provided with a ring-shaped second chute 25 penetrating the upper support body 3.
Bolts pass through the second bolt holes 24 and the second chute 25 in sequence to achieve vertical adjustment and locked fixing of the upper support body 3 and the bottom support body 2.
It should be noted here that the bolts may be ordinary bolts, and the level of the upper support body and the tabletop support body may be adjusted by moving the bolts between the bolt holes and a gap in the groove, thereby adjusting the level of the tabletop; the bolts may also adopt eccentric bolts 26, and the level of the upper support body and the tabletop support body may be adjusted by rotating the eccentric bolts for adjustment, thus adjusting the level of the tabletop, which plays a better role in adjustment, and facilitates better and perfect fixation with an object to be supported; or the above two methods are combined.
Since the upper support body 3 of this structure can be freely tilted on the bottom support body 2, the upper end of the upper support body 3 is fixedly installed with a tabletop support assembling body 10. The level of the tabletop support assembling body 10 can be adjusted by adjusting an inclination angle of the upper support body 3, and the adjustment is simple and fast.
Similarly, an extension plate 12 is installed at the end of the tabletop support assembling body 10 away from the upper support body, and a ring-shaped third chute 18 is formed on the extension plate 12. Bolts pass through the third chute on the extension plate to be fixedly connected to bolt holes on the tabletop support assembling body 10. Gaskets are installed between the extension plate and the bolts, and the upper end surface of the extension plate is provided with screw holes 11, for connecting to the tabletop.
On both sides of the bottom support body 2 and the upper support body 3, two types of screw holes with different diameters are symmetrically provided for installing wooden blocks for fixing the wall.
The working principle or assembling principle of the utility model is as follows: when in use, the base 1 is quickly mounted in an area where it is to be installed by using anchor bolts. Because the upper support body 3 is slidingly installed on the bottom support body 2 correspondingly, the overall height adjustment of the device is realized. The height of the upper support can be adjusted according to actual use requirements, and the upper support can be quickly adapted to walls with different heights for reinforcement work. After the height adjustment is completed, installation bolts are correspondingly passed through installation holes on the upper support and locked by nuts, thus realizing reinforcement and fixation of the upper support. When it is necessary to adaptively fix a tabletop, different forms of tabletop support assembling body structures are adopted in the above Embodiment 2 to Embodiment 4 to meet the needs of the tabletop level adjustment in actual installation scenarios, thus realizing the diversification of market demand. Moreover, the end of the tabletop support assembling body is further provided with an extension structure, and the extension structure can be moved and adjusted horizontally on the tabletop support assembling body, so as to meet the support for the tabletops of different depths. The entire support structure is designed to be adjustable and has a wide range of universality for different projects, so it abandons the main drawback in the prior art that customization is required for specific projects. As a result, the support structure can be batch-produced in advance, so the cost of the support structure can be reduced, which greatly shortens the preparation time and can greatly reduce the scrapping of support structures caused by project design size errors or project size design changes.
Although the embodiments of the utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, replacements, and variations can be made to these embodiments without departing from the principle and spirit of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
