Referring to fig. 6, the side wall of the pull rod 1105 is equidistantly provided with first anti-slip threads 14, the surface of the pull plate 1108 is equidistantly provided with second anti-slip threads 15, so that the friction force between the human hand and the pull rod 1105 and the pull plate 1108 can be improved, and people can conveniently pull the pull rod 1105 and the pull plate 1108.

Referring to fig. 6, the inner wall of the locking hole 1104 is chamfered to facilitate the insertion of the locking post 1102 into the locking hole 1104.

The working principle is as follows: when the device is used, a proper mounting position is selected on the wall surface, the pre-assembly body 1 is mounted on the wall body by inserting screws into the mounting lug plates 2, the distance between the two bolts 33 is adjusted according to the distance between the two through holes 34 on the extension plate main body 6, and during adjustment, the cross rod 53 can be driven to move downwards by pressing the pressing T-bar 54 downwards, so that the first sliding column 52 can be driven to slide downwards along the first sliding sleeve 51, the first sliding column 52 can be separated from the first clamping hole 57, the pressing state of the pressing T-bar 54 is kept, the moving block 31 fixed with the first sliding bar is further pulled, the rack 43 can be pulled to move when the moving block 31 is moved, the gear 42 can be driven to rotate through the rack 43, the other rack 43 is driven to move, and the two moving blocks 31 can be moved towards opposite directions simultaneously, finally, the distance between the extension plate and the through hole 34 is adjusted to match, the T-shaped bar 54 is loosened and pressed, the cross bar 53 is pulled to move upwards under the action of the resilience force of the first spring 55, so that the two first sliding columns 52 can be pushed to slide upwards and be inserted into the two first clamping holes 57 on the adjusted positions, the position of the moving block 31 is fixed, the distance between the two adjusted bolts 33 is fixed, the extension plate main body 6 is installed on the pre-installation body 1, namely the two bolts 33 are inserted into the two through holes 34, the nuts 35 are screwed on the bolts 33, the extension plate main body 6 and the extension plate main body 6 are stably connected, the decorative plate 7 is installed, the clamping plate 9 on the decorative plate 7 is clamped at the end part of the extension plate main body 6, namely the extension plate main body 6 is inserted into the clamping groove 10, the extension plate main body 6 can jack up the self-locking bar 1109 upwards in the inserting process, when the self-locking bar 1109 moves, the second sliding column 1107 can slide upwards along the second sliding sleeve 1106, and finally after the vertical edge of the self-locking bar 1109 is separated from the first self-locking hole 1110, namely, the inclined surface of the self-locking bar 1109 contacts with the inner wall of the first self-locking hole 1110, at this time, the locking function of the self-locking bar 1109 on the locking column 1102 is released, so that the locking column 1102 can be pushed to slide towards one side close to the locking hole 1104 along the connecting sleeve 1101 under the action of the resilience force of the second spring 1103 until the end of the locking column 1102 abuts against the extension plate main body 6, and finally the bottom of the catch plate 9 contacts with the surface of the extension plate main body 6, so as to finely adjust the position of the decorative plate 7 leftwards and rightwards, namely, the catch plate 9 moves leftwards and rightwards along the extension plate main body 6 until the locking column 1102 corresponds to the position of the locking hole 1104, the locking column 1102 can be finally inserted into the locking hole 1104 under the action of the elasticity of the second spring 1103, the inclined surface position of the self-locking bar 1109 can be extruded in the process that the locking column 1102 is inserted into the locking hole 1104, so that the self-locking bar 1109 slides upwards, after the locking column 1102 is completely inserted into the locking hole 1104, the position of the second self-locking hole 1111 corresponds to the position of the inclined surface end of the self-locking bar 1109, the self-locking bar 1109 is inserted into the second self-locking hole 1111 under the action of gravity, the state that the locking column 1102 is inserted into the locking hole 1104 is fixed, and the installation work of the decorative plate 7 is completed;

when the decorative plate 7 is disassembled, the pulling plate 1108 is pulled upwards to drive the second sliding column 1107 to slide upwards, so as to drive the self-locking strip 1109 to slide out of the second self-locking hole 1111, and then the pulling rod 1105 is pulled to drive the locking column 1102 to be pulled out of the locking hole 1104, until the locking column 1102 is pulled to the first self-locking hole 1110 on the surface of the locking column 1102 and the end part of the inclined plane of the self-locking strip 1109 correspond to each other, the pulling plate 1108 is loosened, the self-locking strip 1109 is driven to be inserted into the first self-locking hole 1110 under the action of gravity, so as to clamp the locking column 1102, and then the decorative plate 7 is pulled upwards to separate the clamping plate 9 from the extension plate main body 6, so as to finish the disassembling work of the decorative plate 7;

the invention can effectively improve the efficiency of assembling and disassembling the decorative plate 7, simultaneously can improve the stability of installing the decorative plate 7, and simultaneously can facilitate the installation of the extension plate main bodies 6 with different specifications through the arranged adjustable installing mechanism 3 when the decorative plate 7 needs to be frequently replaced, thereby facilitating the installation of the decorative plates 7 with various specifications.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
