The specific embodiment

Below by specific embodiment, and by reference to the accompanying drawings the technical solution of the utility model is described further.

Embodiment: with reference to Fig. 1, a kind of folding table mainly comprises desktop 1, spacer 2, positioner 3, pin pipe 4, beam pipe 5, hoodle 6, end cover 7, telescoping tube 8, foot pad 9, footmuff 10; It is characterized in that spacer 2 is installed on the desktop 1, positioner 3 is installed on the spacer 2; One end of pin pipe 4 is installed on the positioner 3, and the other end sets firmly end cover 7; Be provided with root beam pipe 5 between the end cover 7; One end of telescoping tube 8 is provided with hoodle 6, and is installed in the pin pipe 4, and the other end is provided with footmuff 10, and foot pad 9 is installed in the corner of telescoping tube 8.

With reference to Fig. 2, positioner 3 comprises handwheel 31, holder 32, adapter 33, screw rod 34, spring 35, locating piece 36; Handwheel 31 is provided with internal thread 311; Locating piece 36 is provided with circular orientation tooth I361, tenon II362, tongue-and-groove I363; Screw rod 34 is provided with guide rod 341, external screw thread 342, tenon I343; Adapter 33 is provided with circular orientation tooth II331, connects pedestal 332; Holder 32 is provided with circle hole groove 321, location wall 322, tongue-and-groove II323; It is characterized in that tenon I343 matches with tongue-and-groove I363, has limited the rotary freedom of guide rod 341; External screw thread 342 can be realized being threaded with internal thread 311; Can realize the location after circular orientation tooth I361 and circular orientation tooth II331 are meshing, restriction adapter 33 rotary freedoms; Connecting pedestal 332 is fixed together by interference fit and pin pipe 4; Spring 35 is installed between adapter 33 and the locating piece 36, and is socketed on the guide rod 341; Locating piece 36 is placed in the circle hole groove 321, when tenon II362 be placed in tongue-and-groove II323 in the time, limited locating piece 36 rotary freedoms.
