As Figure 2-3, the fixed support 1 includes air cylinder fixed plate 11, and is fixedly installed on air cylinder fixed plate 11 1
The supporting part 12 at end.The air cylinder fixed plate 11 takes the shape of the letter U.The supporting part 12 includes two fixed plates 121 be arrangeding in parallel, and sets
Put the first limited block 122 and the second limited block 123 between two fixed plates 121, the first limited block 122 and the second limited block
123 are located at the relative two ends of fixed plate 121 respectively.Axis hole 124 is all offered on first limited block 122 and the second limited block 123,
Axle sleeve 125 is provided with two coaxial lines of axis hole 124, axis hole 124.
As shown in Fig. 2 the drive mechanism 2 includes being fixedly installed on the cylinder 21 of the other end of air cylinder fixed plate 11, and one
End is threaded in the drive rod 23 on the piston rod of cylinder 21 by connector 22.The connector 22 is arranged on air cylinder fixed plate
In 11, the other end of the drive rod 23 runs through air cylinder fixed plate 11, sequentially passes through the first limited block 122 and the second limited block
Axis hole 124 on 123.The axle sleeve 125 is set on drive rod 23, prevents the transverse shifting of drive rod 23.It is appreciated that described
Cylinder 21 can also be hydraulic cylinder, or electrical retractor etc..
In the present embodiment, the linkage 3 includes being symmetricly set on a pair of handgrip parts 31 of the both sides of drive rod 23 and right
Title is arranged on a pair of connecting rods 32 of the both sides of drive rod 23, and is fixedly installed on the 3rd limited block 33 on drive rod 23.It is described
3rd limited block 33 is located between the first limited block 122 and the second limited block 123, and the 3rd limited block 33 mutually hangs down with drive rod 23
Directly.One end of two connecting rods 32 is respectively hinged at the two ends of the 3rd limited block 33, the other end and the handgrip part 31 of connecting rod 32
End be hinged, the 3rd limited block 33 can be supported on the first limited block 122 or the second limited block 123.The handgrip
The part of part 31 is arranged in supporting part 12, and the handgrip part 31 is rotatably arranged in fixed plate 121.The front end of handgrip part 31 is set
There is semicircle draw-in groove 311, two draw-in grooves of handgrip part 31 311 cooperate, for capturing cylindrical objects.It is appreciated that described
Handgrip part 31 can be three or more, and, with drive rod 23 as axle center, uniform ring is around setting for multiple handgrip parts 31.
During work, by the push-and-pull drive rod 23 of cylinder 21, drive rod 23 drives the 3rd limited block 33 in the first limited block 122
And second move between limited block 123, the 3rd limited block 33 drives handgrip part 31 to rotate by connecting rod 32, so as to reach opening and closing
The process of the handgrip；When the 3rd limited block 33 is supported on the second limited block 123, two handgrip parts 31 are in open mode；
Drive rod 23 drives the 3rd limited block 33 to be moved to the first limited block 122, and two handgrip parts 31 start closure；When the 3rd limited block 33
Operation is until when two connecting rods 32 are on same straight line, linkage 3 is in dead-centre position；As shown in figure 4, it is spacing to work as the 3rd
Block 33 is supported when on the first limited block 122, and two handgrip parts 31 are closed, and picks up thing to be taken, extended line and the driving of connecting rod 32
Angle between the direction that bar 23 extends to the second limited block 123 is equal to or slightly less than 90 °, and the handgrip realizes self-locking；Now,
If cylinder 21 runs out of steam, handgrip part 31 has the trend opened in the presence of object gravity, and connecting rod 32 promotes the 3rd to limit
Position block 33 is moved toward the direction of the first limited block 122, because the 3rd limited block 33 is supported by the first limited block 122 so that handgrip part
31 cannot open, and prevent object from dropping；After cylinder 21 recovers power, drive rod 23 is promoted, you can open the handgrip.
A kind of handgrip with auto-lock function described in the utility model, can conveniently be gripped by linkage 3
Object；Using the dead-centre position of linkage 3, the motion of drive rod 23 and connecting rod 32 is limited by the first limited block 122, made
The function that the handgrip reaches self-locking during crawl is obtained, handgrip part 31 does not unclamp after cylinder 21 runs out of steam, and prevents thing
Body drops.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
It is corresponding to change and deformation, and all these change and deformation should all belong to the protection of the utility model claim
Within the scope of.
