[0007] Preferably, a telescopic sleeve is installed on the outer wall of the top of the connecting plate through bolts. A telescopic rod is slidably connected inside the telescopic sleeve. Connecting plates are installed on the outer walls of both sides of the feeding seat through bolts. The threaded rod is movably installed between the connecting plates through bearings. Driving wheels are installed on the outer walls of the threaded rod and the telescopic rod through bolts. A transmission belt is sleeved on the outer wall of the driving wheel. Electric push rods connected to the connecting plate are installed on both sides of the inner wall of the bottom of the rotating groove through bolts.

[0008] Preferably, the connecting plate is threadedly connected to the outer wall of the threaded rod. The curved rod is movably connected to the connecting plate. The curved rod is movably connected to the placing seat through a rotating shaft. The placing seat is slidably connected inside the feeding seat.

[0009] Preferably, the lifting assembly includes a motor. A rotating rod is installed at the output end of the motor through a coupling.

[0010] Preferably, a sliding groove is formed inside the reciprocating threaded sleeve. A sliding rod is slidably connected inside the sliding groove. The top end of the sliding rod is fixed to the outer wall of the bottom end of the turntable through bolts.

[0011] Preferably, the stabilizing assembly includes a movement groove. A transmission rod is movably installed on the inner wall of the top of the movement groove through a bearing. An auxiliary rod is movably installed on the other side of the inner wall of the top of the movement groove through a bearing.

[0012] Preferably, a meshing wheel is installed on the outer wall of the auxiliary rod through bolts. A driving wheel is installed at the bottom end of the outer wall of the auxiliary rod through bolts. A driven wheel that meshes with the driving wheel is installed on the outer wall of the transmission rod through bolts.

[0013] Preferably, a magnetic disk is installed at the bottom end of the outer wall of the transmission rod. A conduction disk is magnetically connected to the bottom end of the outer wall of the magnetic disk. A screw sleeve is movably installed inside the movement groove through a mounting plate. An auxiliary disk is installed at the top end of the screw sleeve through bolts.

[0014] Preferably, a screw rod is threadedly connected inside the screw sleeve. A stabilizing plate is installed at the bottom end of the screw rod through bolts. Limiting pistons are arranged on both sides of the outer wall of the top of the stabilizing plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the present invention, through the stretching component, when the turntable inside the stretching component starts to rotate, the turntable can effectively drive the connecting plate and the telescopic sleeve to rotate synchronously. During the rotation of the telescopic sleeve, it will drive the telescopic rod to rotate together. When the telescopic rod rotates, with the coordinated action of the transmission wheel and the transmission belt, the screw rod is driven to rotate. When the screw rod rotates, through the mutual cooperation of the connecting plate and the curved rod, the curved rod can accurately drive the placing seat to slide. Through such a design, the device can not only quickly and accurately present the exhibits when displaying the security monitoring equipment, facilitating the user to select, but also quickly store the security monitoring equipment, improving the convenience of the user using the device. The cooperative design of the connecting plate and the electric push rod further optimizes this structure.

[0017] 2. In the present invention, through the lifting component, when the motor inside the lifting component starts to operate, the power output of the motor can drive the rotating rod to rotate. During the rotation of the rotating rod, it will drive the conical gear connected to it to rotate synchronously. As the conical gear rotates, with its connection relationship with the connecting rod, the connecting rod will be driven accordingly, and then drive the reciprocating threaded sleeve to move. Through such a set of coherent transmission mechanisms, when the device needs to perform the operation of taking the security monitoring equipment, it can automatically and effectively drive the feeding seat to rise. This innovative design avoids the trouble of manually bending down to take the security monitoring equipment in the existing equipment, effectively improving the convenience and practicality of the device during actual use.

[0018] 3. In the present invention, through the stabilizing component, when the meshing wheel inside the stabilizing component rotates, it can effectively drive the transmission rod to rotate with the coordinated action of the auxiliary rod, the driving wheel and the driven wheel. During the rotation of the transmission rod, it will drive the magnetic disk, the conduction disk and the auxiliary disk to rotate synchronously in sequence. Using the threaded connection structure between the threaded sleeve and the stud, the stabilizing plate can closely and effectively fit the ground. In this way, during the display of the exhibits by the device, through the stabilizing plate in contact with the ground, the stability of the device can be significantly improved, preventing any movement or shaking of the device.
