To realize above-mentioned technical purpose, the utility model employs following technical scheme：
A kind of cutting knife pneumatic jack protection mechanism, it is characterised in that：Including frame, cylinder, connecting plate, rotary shaft and bar is jacked up,
The connecting plate is pivotally mounted in frame by rotary shaft, and the end of the ejection axle of cylinder and one end of jack-up bar connect respectively
The different parts of fishplate bar in succession.
Preferably, the cylinder sets automatic pressure regulator, intake valve and rapid escape valve, rapid escape valve to be used for cylinder
Interior pressure is vented pressure regulation when excessive, during the pulling force that the other end for jacking up bar is back and forth changed by direction, drive cylinder
Axle is ejected to move back and forth；After the external force that the other end for jacking up bar is subject to disappears, the intake valve of cylinder is opened, and cylinder applies one
The individual pressure jacked up to jack-up bar.
Preferably, the cutting knife pneumatic jack protection mechanism is used for cutter, cutter is provided with cutter supporter and active
Mechanism, driving mechanism connect one end of cutter supporter, for driving cutter supporter to pump, cutting knife pneumatic jack protection mechanism
Connect the other end of cutter supporter, apply the power of a jack-up, the top when out of service to cutter supporter for driving mechanism
Play the other end connection cutter supporter of bar.
By adopting the above-described technical solution, the utility model has the following technical effect that：Structure of the present utility model is set
Meter is exquisite, can realize automatic jack-up defencive function, save the energy, improve production efficiency.
Brief description of the drawings
The utility model will illustrate by example and with reference to the appended drawing, wherein：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation that cutting knife pneumatic jack protection mechanism is used for cutter in Fig. 1.
Embodiment

Feature and/or step beyond, can combine in any way.
Any feature disclosed in this specification, unless specifically stated otherwise, can be equivalent by other or with similar purpose
Alternative features are replaced.I.e., unless specifically stated otherwise, each feature is an example in a series of equivalent or similar characteristics
.
A kind of cutting knife pneumatic jack protection mechanism as depicted in figs. 1 and 2, including frame 10, cylinder 1, connecting plate 2, rotary shaft 3
With jack up bar 4, the connecting plate 2 is pivotally mounted in frame 10 by rotary shaft 3, the end of the ejection axle 11 of cylinder 1 and
The one end for jacking up bar 4 connects the different parts of connecting plate 2 respectively, is to set circle in the different parts of connecting plate 2 in the present embodiment
The short axle of cylindricality, it is connected for the ejection axle 11 with cylinder and jack-up bar 4.Cutting knife pneumatic jack protection mechanism in the present embodiment is used for
Cutter 100, cutter 100 are provided with cutter supporter 101 and driving mechanism 20, and driving mechanism 20 connects cutter supporter 101
One end, for driving cutter supporter 101 to pump, cutting knife pneumatic jack protection mechanism connection cutter supporter 101 it is another
Hold, apply the power jacked up to cutter supporter 101 when out of service for driving mechanism 20, jack up the other end connection of bar 4
Cutter supporter 101.As shown in Fig. 2 in the present embodiment, driving mechanism 20 is crank and rocker mechanism, and crank and rocker mechanism includes electricity
Machine 21, synchronous pulley 22, disk 23, the second connecting plate 24, connecting rod 25, clamping plate 26, eccentric shaft 28, some rotating shafts 29 and a top
Rod 210, motor 21 are used to drive synchronous pulley 22 to rotate, and disk 23 is installed on the rotary output shaft of synchronous pulley 22, even
One end of bar 25 is arranged at by eccentric shaft 28 on the eccentric position of disk 23, and rotating shaft 29 connects the other end and second of connecting rod 25
Connecting plate 24, clamping plate 26 are rotatably coupled the second connecting plate 24 by rotating shaft 29, and the second connecting plate 24 connects the another of rotary shaft 3
One end, rotary shaft 3 are long roll shaft, and clamping plate 26 is provided with the axle 27 of connection knock-pin 210, the both ends of knock-pin 210 difference connecting shaft
