According to the invention, the bracket component and the supporting rack are detachably connected, so that the bracket component and the supporting rack can be conveniently mounted and dismounted and the mini-tiller can be for conveniently dismounted, contained and packed; the space heights at the upper end of the second supporting member and the lower side of the third supporting member are higher; the condition of interference between the traditional horizontal wheel shaft and the raised ground during a traveling process is avoided; tools and the travelling wheels need not be exchanged; the mini-tiller is convenient to transfer.

The invention relates to a positioning module, which comprises a frame, wherein the lower part of side wall of frame has a groove whose open is downward; the grooves of opposite edges or nearby edges of frame are connected by the grooves whose opens are downward. The inventive floor is prepared by filling concrete into the groove and into the rectangle frame; and the inventive heater comprises: a coil tube connected to the heater, an insulated layer under the coil tube; said insulated layer has several floors above, whose groove of lower surface is arranged with said coil tube. The inventive module has simple transportation.

The invention provides a method for installing a rotary vane type steering engine. The rotary vane type steering engine is installed in a narrow space by using a method comprising the following steps of: combining the steering engine with a steering engine bushing at first, then lowering a rudderstock and integrally lifting the steering engine, and finally, lifting the rudderstock; the non-vertical quality problem of a rudder line and the axis of a propeller resulted from the installation of the steering engine before a main body building is installed can be avoided; or the difficult installation problem of the steering engine in the narrow space after the main body building is installed can be avoided; the installation space height of the steering engine is increased; the stress condition of a chain hoist in the event of transferring the steering engine can be improved; therefore, the accident risk can be reduced; because the steering engine bushing is placed on a bushing support in the event of installing, the steering engine and the steering engine bushing are tightly combined; therefore, the oil leakage fault can be avoided in the event of injecting hydraulic oil; in the priorart, the whole steering engine is installed for 2-2.5 days; but, the steering engine is installed only for 1-1.5 days by using the method disclosed by the invention; therefore, the working efficiencyis increased.
