Solidity, connecting portion and transition part are one of the forming structure, and the lower end of stand is connected by welding with base.To ensure first rotating shaft
Stability when being installed with the second shaft, the end of the first rotating shaft is equipped with latch, and the end of the second shaft is equipped with snap ring.
The other end of the connecting portion is equipped with mounting hole.This structure facilitates the connection between connecting portion and control target,
And stable connection.
Obtuse angle is formed between the connecting portion and transition part.In the present embodiment, the size at obtuse angle is 100 °~160 °, and blunt
Angle is preferably sized to 120 °.
The stand includes riser portion and lateral piece, and base is fixed in the lower end in the riser portion, and the lateral piece is fixed
In the top in riser portion, the upper end in the riser portion is equipped with spring shaft, and this spring shaft is located at the top of lateral piece, the transition
The front end in portion is installed on lateral piece, upper end and the spring axis connection of the tension spring by the second shaft.This is simple in structure, facilitates it
The installation of his component, and stability is high.The riser portion and lateral piece is integrally formed connects into stand, this stability, ensure that
The reliability of work.
The upper end of the stand is equipped with spacer pin, this spacer pin is located at the top of transition part.Spacer pin can prevent pedal position
When being resetted with hanging scroll, swing is excessive, allows pedal position and hanging scroll quickly to stop and reset.
The hook includes two hook portions and mounting portion, and the lower end of the mounting portion is equipped with hinge hole, the mounting portion
It is connected by hinge hole with first rotating shaft, the lower end of two hook portions is fixedly connected with the upper end of mounting portion, the torsional spring
One end heads on mounting portion, and the other end of the torsional spring heads on base；The upper end of the hook portion is equipped with inclined card slot and bevel edge,

Step ensures functional reliability.Hook portion and mounting portion are integrally formed as linking up with, and ensure that the fastness and reliability of hook.
This is as described below using the operation principle of the mechanical loose card device of service speed control：
When pedal is in initial position, pedal position is parallel with base, and hanging scroll is located at the top of card slot, i.e. this utilization operates
The mechanical loose card device of speed control is in releasing orientation；
After pedal position is pushed, pedal position is rotated around the second shaft.After hanging scroll is contacted with hook, in the effect of lower pressure
Under, continue to push pedal position, even pedal position continues to rotate around the second shaft, and link up with also under the action of hanging scroll, around first
Shaft rotates.And card slot is fallen into after hanging scroll slips over the bevel edge of hook portion, come up pedal position at this time, is acted on by tension spring
Power, hanging scroll, which slowly rises, slips into card slot slot bottom, and hanging scroll is in clamped condition with card slot at this time, i.e., this utilizes service speed control
Mechanical pine card device is in locking state.
When pushing pedal position again, until pedal position is pressed down to extreme position, hanging scroll skids off card slot at this time, at this time：
If the slowly lower pressure of unloading, that is, the lower pressure for the pedal position that comes up, hanging scroll is again slowly along the edge of hook portion
Rising slips into card slot, is clamped again with card slot；
If the lower pressure of moment unloading, i.e., quickly unclamp pedal position, since the coefficient of elasticity of tension spring is more than the elasticity system of torsional spring
Number, then the reset speed of hanging scroll is more than the reset speed of hook, therefore before hook resets, hook has risen above card slot
Position, and continue rising and be returned to original state.
This controls this state using the mechanical loose card device of service speed control, operation using different service speeds
Simply, it is convenient and practical, and reliability is high.
Above-mentioned embodiment is the preferred embodiment of the present invention, can not be limited the invention, and others are appointed
The change or other equivalent substitute modes what is made without departing from technical scheme, are included in the protection of the present invention
Within the scope of.
