The decrement of second spring 21 can be adjusted by the 6th screw 23 to adapt to different rolling operating conditions, when the biggish rolling of needs by applying example
When power, then it is further threaded into the length of the 6th screw 23 compression second spring 21, so that it is enough anti-to have second spring 21
Active force namely operator, which must overcome sufficiently large reaction force just, can be such that the opposite slide bar 20 of the hand handle 22 moves down, thus
It drives the voussoir 18 that the bolt 15 axial movement is made to release the deadlock to the idler wheel 1, realizes the idler wheel 1 to sealant
Item implements rolling installation exercise.Conversely, can screw out the 6th screw 23 when needing lesser rolling power and reduce to the second bullet
The decrement of spring 21, to reduce the power for pushing the hand handle 22 opposite slide bar 20 required when moving down, certainly, the present embodiment can also
The adjusting to required pressure is realized by replacing the second spring 21 of different coefficient of elasticity.
In one feasible embodiment of the utility model, the idler wheel mounting rack 8 is in inverted L-shaped, the inverted L-shaped idler wheel peace
It shelves 8 horizontal top and is reached by the 5th screw 19 with the slide bar 20 and 22 one end is fixedly connected, the 5th spiral shell
Nail 19 is sunk screw, and the vertical side of the inverted L-shaped idler wheel mounting rack 8, which is threadably secured, is provided with multi-diameter shaft 7, the rolling
Wheel 1 is rotatably arranged on the cylindrical surface of the multi-diameter shaft 7 by first bearing 5.
