The principle of the present embodiment is：The telescopic drive bar 521 of driver 52 stretches out, and withstands the second clamping part 4, and it is past
Front promotion, at this moment, has the adverse movement forward of the telescopic drive bar 521 of an opposing driver 52 after jaw pressing plate 56 stress,
Withstand and strutted spring 55 on support arm 2, at this moment support arm 2 has started gradually to begin to erect upset, in the working condition in figure of such as Fig. 3
Can see, driver 52 is to arrange according to certain angle of inclination, lasting the giving of telescopic drive bar 521 of driver 52
So that it may so that support arm 2 gradually produces a resupinate motion when power, but support arm 2 upset touches limited block 11
When, the flip-flop movement of support arm 2 stops, and at this moment, the telescopic drive bar 521 of driver 52 also may proceed to power, jaw pressing plate 56 meeting
Continue, to strutting spring 55 with pressure, to cause and strut spring 55 forced compression, thus realizing the first clamping part 3 and the second clamping part
4 close up clamping.Why two kinds of actions can be realized by a driver 52 in the present embodiment and be because driver 52
The initial power output of telescopic drive bar 521 is F2, and component in an initial condition is F3, F4, F3 be used for overcoming support arm 2 deadweight and
Pin joint produced friction drag overall F1 (i.e. F3*L1>F1*L)；F4 is used for overcoming and struts spring force F5 produced by spring 55
And clamping resistance F6 (i.e. F4>F5+F6)；Support arm 2 is first driven to carry out holding action, this practicality again after putting in place in order to realize singly driving
The size of the oil liquid pressure in the new hydraulic system that refer to oil cylinder variation characteristic with the change of load, is designed as strutting bullet
Spring force F5 produced by spring 55 is more than F3 and F4 (i.e. F5>F4>F3) realize first driving support arm 2, after support arm 2 puts in place, pressure continues
Raise (i.e. F4>F5) realize carrying out again holding action, the size of chucking power is that the maximum pressure of oil cylinder sets.
Specific embodiment described herein is only explanation for example to this utility model spirit.This utility model institute
Belong to those skilled in the art described specific embodiment can be made with various modifications or supplement or using similar
Mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
Although it is resistance to more to employ underframe 1, limited block 11, location hole 12, support arm 2, the first clamping part 3, first herein
Nog plate 31, the first folding portion 311, the second clamping part 4, the second wearing plate 41, the second folding portion 411, drive mechanism 5, hinged seat
51st, driver 52, telescopic drive bar 521, extension 53, installing hole 54, strut spring 55, clamping plate briquetting 56, jaw bearing pin 57,
