There is spring, the end of described trigger unit is contacted with the limit switch being fixed on body frame, and the end of described forced section is fixed with side
Pressing plate.
Described pressure strip and side guide all include top board and lower platen, and described top board and lower platen pass through fixing bolt
Connect.
Described pressure strip and side guide are rectangle.
It is equipped with semi-circular recesses on described top board and lower platen.
Described body frame is equipped with backplate with the both sides of the hinged one end of inner support.
The upper and lower ends of described backplate are provided with bending, and the backplate positioned at body frame both sides is oppositely arranged.
The described base plate position corresponding with pressure strip is provided with string holes.
, all using channel-section steel, the channel-section steel model that described body frame uses is more than the channel-section steel that inner support uses for described body frame and inner support
Model.
The beneficial effects of the utility model are：
1st, the utility model when cage rise or decline during cable tangled when, inner support can touch spacing holding
Pass makes cage power-off, the operation safety of protection cage；
2nd, the utility model is simple for production, and usage safety performance is high, is prevented effectively from because of operating personnel's level of skill height not
With the unsafe factor bringing.

Specific embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of arm support with two-way scratch resistant disconnected function, including base plate 1, body frame 4, inner support 13,
One end of described body frame 4 is vertically fixed on base plate 1, as shown in figure 5, the other end passes through bearing pin with the centre position of inner support 13
12 is hinged, so that inner support 13 is rotated with respect to body frame 4 centered on bearing pin 12, and the top surface of described body frame 4 is fixed with pressure
Tight plate 2, described base plate 1 position corresponding with pressure strip 2 is provided with string holes.As shown in fig. 6, described inner support 13 includes forced section
6 and trigger unit 8, described forced section 6 and trigger unit 8 integrally connected, junction is provided with pin-and-hole, and described trigger unit 8 is located at body frame 4
Interior, as shown in figure 4, the underrun caging bolt 10 of described trigger unit 8 is connected with body frame 4, described caging bolt 10 is set with
Have spring 9, described spring 9 plays reset role to inner support 13, the end of described trigger unit 8 be fixed on spacing on body frame 4
Switch 11 contact, when inner support 13 rotates around bearing pin 12, inner support 13 touches limit switch 11, makes limit switch 11 power-off,
The end of described forced section 6 is fixed with side guide, and cable 3 sequentially passes through side guide, the top surface of body frame 4, pressure strip 2, then
Passed by the string holes on floor, enter in cage.
