A rotary telescopic mechanical arm capable of rotating omni-directionally comprises a first gear and a second gear which are engaged with each other. The first gear is connected with a first support through a first rotary shaft. The second gear is connected with a second support through a second rotary shaft. Connecting arms are arranged between the first rotary shaft and the second rotary shaft. The first rotary shaft is connected with a first drive device, and the first support is connected with a second drive device. The second support is connected with a telescopic external mechanical arm. A lead screw device is arranged in the external mechanical arm. The external mechanical arm comprises a first mechanical arm body and a second mechanical arm body. The lead screw device comprises a lead screw and a nut arranged on the lead screw in a sleeving manner. One end of the lead screw is connected with the first mechanical arm body, and the other end of the lead screw is arranged in a hollow cavity of the second mechanical arm body. The periphery of the nut is fixedly connected with the inner wall of the hollow cavity of the second mechanical arm body. The mechanical arm can stretch and contract and rotate omni-directionally, and has the beneficial effects of being simple in structure and low in cost.

The invention discloses an adjustable emergency lamp support which comprises a left sliding groove, a right sliding groove and an electric telescopic rod. A sliding plate is connected between the left sliding groove and the right sliding groove. Sliding blocks are connected to the two ends of the sliding plate. The electric telescopic rod is connected with the bottom of the sliding plate. A left support and a right support are fixedly connected to the upper end face of the sliding plate. A rotating shaft is connected between the left support and the right support. A lamp holder is rotationally connected to the rotating shaft, and an emergency lamp is connected to the lamp holder. According to the adjustable emergency lamp support, the sliding blocks at the two ends of the sliding plate ascend and descend between the left sliding groove and the right sliding groove through the electric telescopic rod, and therefore a user can adjust the height according to practical requirements in the using process; and due to the fact that the lamp holder is connected with the rotating shaft through a rotary sleeve, the emergency lamp can achieve 360-degree all-directional rotation, and use is quite convenient.

The invention discloses a telescopic mechanical arm capable of rotating in an omnibearing manner. The telescopic mechanical arm comprises a first gear and a second gear which are engaged with each other. The first gear is arranged on a first rotating shaft in a penetrating manner and connected with a first support through the first rotating shaft. The second gear is arranged on a second rotating shaft in a penetrating manner and connected with a second support through the second rotating shaft. Connecting arms are arranged between the first rotating shaft and the second rotating shaft. The first rotating shaft is connected with a first drive device. The first support is connected with a second drive device. The second support is connected with a telescopic external mechanical arm. The external mechanical arm comprises a first mechanical arm body and a second mechanical arm body. One end of the second mechanical arm body is arranged in a hollow cavity of the first mechanical arm body. A gear and rack mechanism is arranged between the first mechanical arm body and the second mechanical arm body. Extension and retraction and omnibearing rotation of the mechanical arm can be achieved, and the telescopic mechanical arm has the beneficial effects of being simple in structure, low in cost, stable in structure and reliable in transmission.

The invention discloses a direction operating mechanism for an intelligent body building vehicle. The direction operating mechanism comprises an upper fixing plate, a lower fixing plate, a rod end joint bearing and an elastic body, wherein the upper fixing plate can be fixed with a handlebar of the intelligent body building vehicle, the lower fixing plate can be fixed with a vehicle frame of the intelligent body building vehicle, the elastic body can realize the reset function, the rod end joint bearing comprises a rod end and a support body used for supporting the rod end to realize the 360-degree omnibearing swinging, the support body of the rod end joint bearing is fixedly connected with the lower fixing plate, the rod end of the rod end joint bearing passes through the elastic body to be fixedly connected with the upper fixing plate, the elastic body is supported and propped between the upper fixing plate and the lower fixing plate so that the handlebar connected with the upper fixing plate can realize the 360-degree omnibearing swinging in a manner relative to the vehicle frame connected with the lower fixing plate, and in addition, the resetting is realized. The structure can provide the 360-degree omnibearing steering action, the fast original position returning can be realized after the steering force elimination, and the direction operating mechanism has the characteristics that the manufacture is simple, the manufacture cost is low, the realization is easy, the collected signals are accurate, the sensitivity is high, and the operation is convenient.
