Thrust ball bearing component 162 and positioning ball bearing assembly 161 are included, thrust ball bearing component 162 is arranged at the upper end of connector 132
Portion, positioning ball bearing assembly 161 is arranged at the bottom of connector 132.In the present embodiment, the upper end at least portion of connector 132
It is divided into hollow tubular, inside pipe wall is provided with internal thread, and lid 153 is correspondingly arranged on a through hole, and screw passes through the through hole and is connected
The upper end screw thread of part 132 coordinates the fixation for realizing connector 132 and adaptor 15；The bottom of connector 132 includes and drive
The threaded portion 132b of the threaded adapter at the second end of dynamic pipe 131 and a smooth axle portion (not shown), the smooth axle portion is close to screens
Boss 132c, is not provided with external screw thread, and external diameter is equal with the external diameter of upper end, and threaded portion 132b extends downwardly shape by the smooth axle portion
Into, be provided with some external screw threads, the threaded portion 132b extend into the first end of driving tube 131, and with the first end pipe in
Screw thread coordinate, connector 132 is fixed with driving tube 131.It is appreciated that bearing arrangement is wide variety of in prior art
One kind transmission dependency structure, apply in the design, be conducive to strengthen driving tube 131, between connector 132 and adaptor 15
The smoothness being driven mutually and stability.
With reference to Fig. 2 and Fig. 7, wherein in one embodiment, positioning ball bearing assembly 161 includes a positioning ball bearing
161a, positioning ball bearing 161a are arranged at the light axle portion of the bottom of connector 132, and light axle portion passes through positioning ball bearing 161a
Inner ring so as to be fixed on light axle portion.It is appreciated that positioning ball bearing 161a is set, it is advantageously ensured that driving tube 131 and company
Transmission between fitting 132 is carried out in positive vertical direction, it is to avoid transmission is stuck.It should be noted that the design not limited to this, in
In other embodiment, in order to better ensure that slow-roll stabilization between driving tube 131, rotating shaft 112 and connector 132, place kick
Bearing assembly 161 may also include multiple positioning ball bearing 161a for playing the role of positioning.Preferably, the first end external diameter of driving tube 131
More than the external diameter of the smooth axle portion, also greater than the diameter of positioning ball bearing inner race.
Further, with reference to Fig. 2 and Fig. 6, through hole radially extends to form a convex annular away from the inwall of the one end of erecting bed 12
Platform 151a, is provided with the perforation passed through for the upper end of connector 132 in the middle of annular boss 151a.With reference to Fig. 3, Fig. 6 and Fig. 7, this reality
In applying example, thrust ball bearing component 162 includes two thrust ball bearing 162a, and the upper end of connector 132 wears two thrusts
Ball bearing 162a, so that two thrust ball bearing 162a are anchored on the upper end, two thrust ball bearing 162a are respectively provided with
In the both sides of annular boss 151a, specifically, a receiving space is formed between annular boss 151a and clamping boss 132c, its
In a thrust ball bearing 162a be arranged in receiving space, another thrust ball bearing 162a be arranged at annular boss 151a with lid
Between body 153.It is appreciated that the design of two thrust ball bearing 162a can be used to offset the stress of above-below direction, it is concrete and
Speech, when driving tube 131 promotes connector 132 to move upwards, connector 132 bears thrust upwards, and the thrust is by positioned at annular
Thrust ball bearing 162a on the downside of boss 151a undertakes；Conversely, when driving tube 131 pulls connector 132 to move downward, connector
132 bear downward pulling force, and the pulling force is undertaken by the thrust ball bearing 162a on the upside of annular boss 151a；Thus, i.e. preferably
Improve the stability being driven between driving tube 131, connector 132 and adaptor 15 in the rotation process of rotating shaft 112, it is to avoid appoint
One structure is excessive because of stress, and deformation is damaged.
It is that first embodiment of the invention folds the schematic diagram for drawing structure in reference to Fig. 8 to Figure 12, in the present embodiment, drives
Device is a reducing motor 11, and reducing motor includes motor body 111 and machine shaft 112, and the second end of driving tube 131 is provided with
Internal thread, for coordinating with the screw thread of machine shaft 112, in addition, the second end of driving tube 131 is additionally provided with gag lever post 131a.
Being applied to the positioning ball bearing assembly 161 of the driving means also includes another positioning ball bearing 161a, the place kick
Bearing 161a is arranged at machine shaft 112 near one end of motor body 111, it will be understood that two positioning ball bearing 161a are upper and lower
It is oppositely arranged, it is advantageously ensured that the transmission between machine shaft 112, driving tube 131 and connector 132 is entered in positive vertical direction
OK, it is to avoid transmission is stuck；Meanwhile, it is arranged such, can also make the transmission of machine shaft 112 more smoothly.
Object to be drawn in by taking blade 3 as an example, draw the course of work of constructive embodiment in and be specially by the folding：Reducing motor 11
Motor rotating shaft 112 is rotated forward, and machine shaft 112 drives driving tube 131 to do close subtracting along the axial direction of machine shaft 112
The motion of speed motor 11, because driving tube 131 is fixedly connected with connector 132, therefore, driving tube 131 applies to connector 132
One downward pulling force, now the thrust ball bearing 162a on the upside of clamping boss 132c meets with stresses, and pulls the edge of adaptor 15
The axial downward movement of driving tube 131, lever piece 14 is connected one end and moves relatively downward with adaptor 15, away from the one end of connector 15
That is one end relative upward movement of fixed blades 3, blade 3 completes the gathering of blade 3 from deployed condition to rounding state transition
Journey.
Conversely, the motor rotating shaft 112 of reducing motor 11 is rotated backward, machine shaft 112 drives driving tube 131 along electricity
The motion away from reducing motor 11 is done in the axial direction of machine rotating shaft 112, because driving tube 131 is fixedly connected with connector 132, therefore,
Driving tube 131 applies a thrust upwards to connector 132, and now the thrust ball bearing 162a on the downside of clamping boss 132c holds
By stress, and promote adaptor 15 moved axially upward along driving tube 131, lever piece 14 and adaptor 15 connection one end it is relative to
Upper motion, is that the one end of fixed blades 3 is moved relatively downward away from the one end of connector 15, and blade 3 is from rounding state to deployed condition
Transition, completes the expansion process of blade 3.

64 vert to the applying power of pull-push piece 7, makes pull-push piece 7 from the top of the first chute 651 in the first installing plate 65 along first
The slide downward of chute 651, then pull-push piece 7 to driving tube 131 apply a pulling force along the axial direction of driving tube 131, via driving tube
131 are delivered to connector 132, and now the thrust ball bearing 162a on the upside of clamping boss 132c meets with stresses, and pulls adaptor
15 along the axial downward movement of driving tube 131, and lever piece 14 is connected one end and moves relatively downward with adaptor 15, away from connector
132 one end are one end relative upward movement of fixed blades 3, blade 3 from deployed condition to rounding state transition, this process erecting bed
12 motion is consistent with the motion of the part 64 that verts.
