Preferably, the both ends of the worm screw are rotationally connected with outer support column, and one end of worm screw is equipped with lifting handle.
Preferably, the front side on the chassis is opening extension type structure.
The technical effect and advantage of the utility model:
1, the main part of referee's chair is designed as removable, substantially reduces volume when packaging, transport easy to remove；
2, the lower half portion design volume of referee's chair is greater than top half and does not need so as to improve the stability used
Excessively bulky clump weight is set on chassis, considerably increases the reduction for transporting convenience and transportation cost on the move；
3, the design principle that height adjusting system is adjusted using the rotation of worm gear drive screw rod, such design is regulated the speed fast
It is prompt, laborsaving, and can be effectively prevented and avoid the case where standing table height declines in load-bearing use；
4, chassis is preamble part opening design, and such design can have been realized with vollyball (Air volleyball) frame with ballast box
Beauty combines, and volleyball frame counterweight box part is directly placed into the chassis of opening, in maximal efficiency using also real outside athletic ground
Show and has allowed referee can be with the situation in optimum distance, angle observation match；
5, the outer support column of this referee's chair, inner support post design mention significantly in the close central supported point position of standing table
High referee stability and safety in use.
