The rotating shaft of portion both sides sets screw rod bushing and reducing motor respectively, and the output shaft of reducing motor is connected to more piece screw mandrel, more piece screw mandrel
It is socketed in screw rod bushing.
Preferably, more piece screw mandrel includes first segment screw mandrel, second section screw mandrel and Section of three screw mandrel, second being socketed successively
Save the leading portion on the inside of screw mandrel and Section three screw mandrel and internal thread be set, internal thread herein respectively with first segment screw mandrel and second section thread
The external screw thread of bar is used in conjunction with each other.
Preferably, the left end of first and second section screw mandrel sets internal limited block, and the right-hand member of second section screw mandrel sets outside spacing
Block, the left end of Section of three screw mandrel sets block.
Preferably, the upper end of upper supporting arm and the lower end of lower support arm set meshing gear respectively, the upper supporting arm and
Meshing gear between lower support arm is intermeshed respectively.
Preferably, upper supporting arm and lower support arm is distributed in scissors.
Compared with prior art, the utility model has the advantages that：
The utility model structure is novel, easy to use, small volume, conducts oneself with dignity lighter, bearing capacity is larger, using more piece silk
Bar, screw mandrel protrusion length is shorter, supporting arm intermeshing, more consolidates, is difficult to rock, security performance is higher, reduces safety
Hidden danger.

Embodiment
The utility model embodiment is described further below in conjunction with the accompanying drawings：
Embodiment 1
As shown in Figure 1-2, the driving of more piece screw mandrel 7 lowering or hoisting gear described in the utility model, including base 6 and lifting platform 1,
The lower end of lifting platform 1 sets mounting seat 11, and the upper supporting arm 2 being arranged in pairs and lower branch are installed between base 6 and lifting platform 1
Bearing arm 4, upper supporting arm 2 and lower support arm 4 are distributed in scissors, and upper supporting arm 2 is arranged in mounting seat 11 by rotating shaft 10, base
6 inside sets installation cavity, and lower support arm 4 is arranged in installation cavity by rotating shaft 10, the upper end of upper supporting arm 2 and lower support arm
4 lower end sets meshing gear 5 respectively, and the meshing gear 5 between the upper supporting arm 2 and lower support arm 4 is intermeshed respectively,
The lower end of upper supporting arm 2 and the upper end of lower support arm 4 are connected with each other by rotating shaft 10, and the rotating shaft 10 of the middle part left and right sides is opened respectively
Set if mounting hole, in the mounting hole in left side and reducing motor 3 be set at screw rod bushing 9, the mounting hole on right side, reducing motor 3 it is defeated
Shaft passes through mounting hole, and is connected to more piece screw mandrel 7, and more piece screw mandrel 7 is socketed in screw rod bushing 9.
More piece screw mandrel 7 includes first segment screw mandrel 13, second section screw mandrel 16 and Section of three screw mandrel 17 being socketed successively, above-mentioned
The outside of screw mandrel sets external screw thread, herein, and first segment screw mandrel 13 passes through mounting hole and defeated with the reducing motor 3 installed in right side
