Seat stretching motion.
Also comprising the fixation kit being fixedly connected with described screw rod one end, described screw rod one end is equipped with diameter and is less than the silk
The fixed column of bar simultaneously forms fixed step with the screw rod, and the fixed column center is equipped with internal screw thread；The fixation kit includes
Fixed pad and fixed plate, described fixed plate one end, which is equipped with to be equipped with the fixation hole other end of the fixed column counter structure, places institute
The mounting groove of fixed pad is stated, the mounting groove is correspondingly arranged with fixation hole, and the fixed pad is equipped with perforative screw hole, the spiral shell
Wire hole is correspondingly arranged with the internal screw thread.
The fixation hole through the fixed plate is additionally provided in the fixed plate.
The utility model beneficial effect: structure is simple, and bearing block is common accessory, and screw rod can choose normal full tooth spiral shell
Screw rod, screw rod bushing can be processed using machine tool, cheap；
It is fixed when in use by bearing block, by driving screw rod bushing rotation, realizes that driving screw rod is for linear motion,
Not needing fixed frame installation can be used, easy to use；
It drives screw rod rotation, can also realize the linear motion of screw rod bushing, usage mode multiplicity；
Fixation kit, it may be convenient to screw rod and driven object product are fixed, it is easy to use.
