Preferably, described stand base is ring; Adopt annular stent pedestal, be convenient to the rotation by transmission mechanism control stand base.
Preferably, described stand base ring-shaped inner wall is provided with internal tooth; By arranging internal tooth arrangement, stand base is engaged by internal tooth with driving mechanism, to realize the control of driving mechanism to stand base.
Preferably, described stand base edge is also extended with at least one platform; By arranging platform, the control chip of CCTV camera can be fixed on platform.
Preferably, described platform is provided with circuit board screw fixing column; Utilize circuit board screw fixing column, by fastening for the control chip of CCTV camera, avoid control chip to come off from platform.
Preferably, described fixing support arm is symmetrical arranged; Fixing support arm is symmetrical arranged the whole machine balancing being conducive to ensureing support.
Preferably, described platform is between two fixing support arms.
The beneficial effects of the utility model are, the fixed end of fixing support arm is connected by rotating shaft with external part, and the fixed end of fixing support arm and telescopic end can be made to relatively rotate;
By extending means, the distance between the fixed end of fixing support arm and telescopic end is adjusted;
Can make, between flexible rod and screw shell, relative movement occurs by rotating screw shell, thus play the effect of the fixing fixed end of support arm of adjustment and the spacing of telescopic end;
By the fixed shaft hole that fixing support arm is arranged, fixed camera camera lens is installed; In addition, the utility model design principle is reliable, and structure is simple, has application prospect widely.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and its beneficial effect implemented also is apparent.
