As a further aspect of the present invention: the lower stand is composed of five single-column stands, except that the tops of all the stands are movably arranged on the chassis through L-shaped supporting connecting pieces, the middle of each stand is not connected, and the five single-column stands can be separately folded, so that the manual operation is convenient. According to actual needs, the number of sectors of the single-row watching platform can be increased or decreased.

As a further aspect of the present invention: the traction rod is fixedly arranged at the front end of the chassis, and can be directly manually towed and hauled by using a common vehicle.

As a further aspect of the present invention: the hand-operated supporting legs can be reasonably arranged on two sides of the stand and corresponding stress points according to the length of the stand. After the stand reaches the appointed deployment position, the stand is kept at the required height by the extension of the hand-operated supporting legs, and the effect of stable support is achieved.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses a set up the chassis, go up the stand, L type support connecting piece's cooperation is used down, realizes the manual unilateral folding function of stand, full mechanical structure, and is easy and simple to handle, and the fault rate is low, and the reliability is high, can be on a large scale, stride the venue, stride regional, low-cost quick travel use, and the product turnover rate is high, and the high-usage can use under indoor, outdoor, different ground condition and environment.

2. The utility model provides a lower stand comprises five single stands, removes every top and all supports connecting piece movable mounting on the chassis through the L type, and middle unconnection, five single stands detachable are folding, the manually operation of being convenient for. According to actual needs, the number of sectors of the single-row watching platform can be increased or decreased.

3. The utility model provides a chassis is according to load index demand installation rubber tire, can directly artifically and use ordinary vehicle to pull the haul, conveniently remove and transregional long-distance transport.

4. The utility model provides a stand length can be adjusted according to the in-service use demand, and hand supporting leg can be at stand both sides girder and corresponding stress point rational arrangement many sets according to stand length. When the chassis reaches the designated installation position, the hand-operated supporting legs are controlled to extend to keep the chassis at the required height. Simple operation, high stability, high reliability and firm support.
