When the monitoring camera needs to be maintained, the monitoring camera can be controlled to descend to the bottom of the connecting plate through rotating the gear, so that maintenance personnel can maintain the monitoring camera conveniently. In this application, because the mounted position of connecting plate can be in higher position, avoided child to rotate the gear and lead to surveillance camera head to go up and down to certain potential safety hazard has been avoided.

Further, an installation box is arranged on the outer wall of the connecting plate, and the gear is installed in the installation box. Through the setting of mounting box, avoid the gear direct exposure outside.

Further, be equipped with the handle on the mounting box, the one end and the gear fixed connection of handle, the other end of handle extends outside the mounting box. Through the setting of handle, be convenient for through handle rotation gear to control gear that can be more convenient rotates.

Further, the handle is connected with a screw rod through threads, and a threaded hole matched with the screw rod is formed in the connecting plate. Through the setting of screw rod and screw hole, when surveillance camera head accomplishes the installation or carries out the maintenance, through the connection of screw rod and screw hole, avoid gear rotation.

Further, a limiting bar is arranged on the rack, and a limiting groove matched with the limiting bar for use is arranged in the connecting plate. Through the setting of spacing and spacing groove for the rack is more steady in the lift in-process.

Further, fixedly connected with installation piece on the connecting plate, the one end that the connecting block was kept away from to the chain can dismantle the connection on the installation piece. The chain is detachably connected to the mounting block, so that the mounting box of the chain can be conveniently detached.
