The course of work of the present embodiment is described below with reference to Fig. 7 to 9, it is necessary first to explanation, in the present embodiment
Preferably when motor 301 drives chain 1 to rotate so that the supporting part 4 close to 6 side of apparatus body is along apparatus body 6
Descent direction moves.At this time, as shown in fig. 7, can be abutted in 6 uphill process of apparatus body with supporting part 4, due to 4 turns of supporting part
Dynamic to be arranged on chain 1, as shown in figure 8, with the rising of apparatus body 6, relative to chain 1, gradually fold is in perpendicular to support plate 1011
Straight state, not influence the rising of apparatus body 6.As shown in figure 9, apparatus body 6 continues after rising and passing through support plate 1011,
The self-return under the effect of gravity of support plate 1011, and support end 403 is located on the lift path of apparatus body 6, with can be to prominent
The apparatus body 6 so to drop is supported.
And when apparatus body 6 declines, since the movement velocity of supporting part 4 is not less than the decrease speed of apparatus body 6, because
This supporting part 4 will not impact the decline of apparatus body 6, and the support end of the supporting part 4 due to the lower section of apparatus body 6
On the lift path of apparatus body 6, if thus apparatus body 6 drop suddenly, supporting part 4 can also carry out apparatus body 6
Support, prevents falling accident.
Certainly, except the above-mentioned supporting part 4 close to 6 side of apparatus body that causes is moved along 6 descent direction of apparatus body,
Also can be by controlling the rotation direction of motor 301 in the present embodiment, and cause when apparatus body 6 rises, positioned at apparatus body 6
The supporting part 4 of side is identical with 6 ascent direction of apparatus body, when apparatus body 6 declines, the branch positioned at 6 side of apparatus body
Support part 4 is again identical with 6 descent direction of apparatus body.But, then need at this time as previously described, when apparatus body 6 rises, support
The movement velocity in portion 4 need to be not higher than apparatus body 6, and when apparatus body 6 declines, and the movement velocity of supporting part 4 then needs not low
In apparatus body 6.
In addition, in the present embodiment it should be noted that, except cause supporting part 4 be along circumferentially multiple in addition to chain 1, when
Preceding also to may be such that the supporting part 4 is only to be provided with one, at this time, which should be the close and equipment sheet for being arranged on chain 1
The side of body 6, and supporting part 4 should also be located at the lower section of apparatus body 6.Meanwhile supporting part 4 be only one when, supporting part 4 with
The forms of motion of chain 1 also should be foregoing, by controlling the rotation direction of motor 301, when apparatus body 6 rises, and branch
Support part 4 is identical with 6 ascent direction of apparatus body, and when apparatus body 6 declines, supporting part 4 then with 6 descent direction of apparatus body
It is identical, support can be provided to apparatus body 6 with this, and realize anti-falling function.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on, should be included in the utility model
Protection domain within.
