Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Referring to fig. 1 and 2, a portable survey and drawing tripod, including roof 1, three connecting rod 2 is installed through slewing mechanism in 1 bottom of roof, and the interval sets up in the middle of three connecting rod 2, three connecting rod 2 all is connected with first bracing piece 3 through hinge mechanisms, three first bracing piece 3 is hollow pole, a plurality of external screw threads 5 have all been seted up from top to bottom in proper order in the 3 outsides of three first bracing piece, 3 bottom outsides of three first bracing piece all overlap and are equipped with second stay tube 4, internal thread 6 has all been seted up to 4 top inner walls of three second stay tube, clearance fit between external screw thread 5 and the

internal thread

6, 4 bottoms of three second stay tube all block and are equipped with antiskid cover 13. A plurality of external threads 5 are formed in the outer side of the first supporting rod 3, and the length between the first supporting rod 3 and the second supporting rod 6 can be adjusted through the internal threads 6, so that an adjustable telescopic rod is formed, the device is convenient to carry in a contraction state, and the length between the first supporting rod 3 and the second supporting rod 6 can be adjusted to enable the device to be suitable for the condition of uneven ground. Set up three first bracing piece 3 and be hollow pole to weight reduction, portable. The anti-skidding sleeves 13 are clamped at the bottom ends of the three second supporting tubes 4, so that the anti-skidding performance of the device is improved, and the phenomenon that the device slides is avoided.

Referring to fig. 2, 3 and 4, the hinge mechanism includes U type card 7, the welding of welding in the bottom of connecting rod 2 and the connector 10 on 3 tops of first bracing piece, and bolt 8 has been placed to U type card 7 one side, and bolt 8 runs through U type card 7, connector 10 and extends to U type card 7 opposite side threaded connection has nut 9, interference fit between bolt 8 and the connector 10.
