Lock screw mechanism-long 3D model

Lock screw mechanism, the institution and ordinary simple electric motor lock screw mechanism is different, the agency for super, super long screw mechanism, through the bearing,universal coupling, universal shaft coupling and a series of institution, lock rod lengthen, but can be used within the range 0-800 mm, very clever design, the model using the need to avoid the situation in some special cases, or interfere in institutions, all can use this module, the classic design.Through the modules, the platform is also included in the cylinder, and the two platforms and the multi-stage platform are also the classic design schemes. if you like,you can paypal for you to get this models or if you have any questions also you can email to me.
