Very little, weight and using scene need be designed.
In order to realize the control of relative position between fixed friction piece 311 and rotary friction pad 321, described in the present embodiment
Support frame also include be used for control the control that the fixed friction piece 311 is contacted with each other or separated with the rotary friction pad 321
Component 4 processed.
Specifically, control assembly 4 described in the present embodiment includes control-rod 401, the control-rod 401 can drive described solid
Friction plate 311 is determined to the position movement closer or far from the rotary friction pad 321.The control-rod 401 is simultaneously through described
Fixed friction piece 311 and the rotary friction pad 321, arc chute 402 is provided with the rotary friction pad 321, works as institute
The control-rod 401 when rotary sleeve 32 rotates relative to the fixed seat 31 is stated to slide in the arc chute 402.This programme
During rotating against, the relative position of fixed seat 31 and control-rod 401 is fixed, and rotary sleeve 32 drives rotary friction pad
321 rotate, and the purpose for setting arc chute 402 is to prevent control-rod 401 from interfering with rotary sleeve 32.
The control assembly 4 includes being used to control the fixed friction piece 311 to move to the direction of rotary friction pad 321
Compression spring 403, and for releasing the compression spring 403 to the active force of the fixed friction piece 311 by pressure handle
Hand 404.
The control assembly 4 also includes control-rod 401, the control-rod 401 can drive the fixed friction piece 311 to by
Moved close or remote from the position of the rotary friction pad 321, the compression spring 403 is set on the control-rod 401, described
Squeeze grip 404 is be hinged with the fixed seat 31, and has the alternative extruding control-rod in the squeeze grip 404
401 control boss 405.
Compression spring 403 act as to the fixed friction piece 311 provide one moved to the direction of rotary friction pad 321
Active force so that fixed friction piece 311 contacts with each other with rotary friction pad 321, in fixed friction piece 311 and spin friction
In the case that the quantity of piece 321 and the area that contacts with each other are certain, the size of the elastic force of compression spring 403 determines fixed seat 31 and rotation
Frictional force size between set 32, and then determine that thing 5 to be supported overturns required active force.Squeeze grip 404 is act as pair
Control-rod 401 provides a thrust opposite with the active force of compression spring 403, is needing to release fixed friction piece 311 and rotation
The control-rod 401 is promoted by squeeze grip 404 in the case of contact between friction plate 321, to compression spring 403
Elastic force direction in opposite direction is moved, and in this motion process, compression spring 403 is further compressed, fixed friction piece 311 and rotation
Turn the frictional force between friction plate 321 to diminish or even disappear.
Specifically, also include being used for the control mounting seat 406 for installing the control assembly 4, the control in the present embodiment

Power micro-adjusting mechanism includes being set on the control-rod 401 and with the nut 414 for the internal thread being engaged with the external screw thread.
By the cooperation of internal thread and nut 414, in the case where needing to adjust initial frictional, rotary nut 414 is controlling it
Moved on bar 401 along the axis direction of control-rod 401, closer to fixed friction piece 311, then caused processing frictional force is bigger, when
It diminishes to the lateral movement away from the fixed friction piece 311, then initial frictional, and the size of initial frictional is according to reality
Use need be adjusted, in the case that the access times of switching mechanism 3 relatively mostly occur abrasion, rotatable nut 414 makes it
Further towards fixed friction piece 311, increase frictional force.
It is micro- in the clamping force in the present embodiment in order to prevent the stress of nut 414 is excessive in use from loosening
Regulating mechanism also includes the Anti-slip cover being equally set on the control-rod 401, and the Anti-slip cover has to match with the external screw thread
The internal thread of conjunction, the nut 414 are arranged between the Anti-slip cover and the fixed friction piece 311.
The clamping force micro-adjusting mechanism also includes diffusion sheet, and the diffusion sheet is set in the nut 414 and the fixation
Between friction plate 311, by setting diffusion sheet to increase the contact area of clamping force micro-adjusting mechanism and fixed friction piece 311,
Avoid clamping force micro-adjusting mechanism from causing the active force undue concentration of fixed friction piece 311 fixed friction piece 311 depression occurs to become
