Specific embodiment
Embodiment：
As illustrated in the accompanying drawings from 1 to 3, a kind of unpowered parallel clamping device, including two clamping pieces 1 and two groups of drawing mechanisms 2；It is described
The L-shaped that two clamping pieces 1 are 90 ° in angle, head and the tail are connected to form a rectangle by two groups of drawing mechanisms 2 respectively,
The interior zone that two clamping pieces 1 surround is clamp area；One of clamping piece 1 can by drawing mechanism 2 under external force
It diagonally stretches out with respect to another clamping piece 1, is resetted under the effect of the restoring force of drawing mechanism 2 after removal external force；
Two clamping pieces 1 can be known as geometrical clamp gripping member 11 and moveable gripping member 12, i.e. geometrical clamp gripping member according to relative motion relation
11 be a relatively-stationary clamping piece, and moveable gripping member 12 is a clamping piece for receiving to relatively move after external force；Due to this
The unpowered parallel rectangular shape of clamping device in embodiment, therefore drawing mechanism 2 described in every group is by two orthogonal drawings
Component composition is stretched, each stretching assembly includes elastic element, guide part and telescopic block, and one end of the elastic element is fixed
On clamping piece 1, the other end is fixedly connected with telescopic block, and two telescopic blocks are fixedly connected；It is provided on the elastic element
Elasticity adjusting device 4, elasticity adjusting device 4 are used to adjust the tensile elongation or reduction length of elastic element.
As shown in attached drawing 2,4, opened up on the upper surface of the both ends end of the geometrical clamp gripping member 11 there are two spring install
For installing two stretching assemblies, cover board 35 is detachably provided in the spring mounting groove 34 for slot 34；Wherein described elasticity member
Part is spring 31, and guide part is guide rod 32；One end end sleeve of the guide rod 32 is equipped with guide sleeve 36, the guide sleeve 36 and telescopic block
It is fixedly connected；The spring 31 is sheathed on outside guide rod 32, and one end of spring 31 is fixedly connected with guide sleeve 36, and the other end passes through bullet
Property adjuster 4 is fixedly connected on guide rod 32；The guide sleeve 36 can slide, and install under the elastic force effect of spring along guide rod 32
It is simple in structure and compact in geometrical clamp gripping member 11.
As shown in attached drawing 3,4, opened up on the lower face of the both ends end of the moveable gripping member 12 there are two tension spring install
Slot, for installing two stretching assemblies, wherein the elastic element is tension spring 41, guide part is sliding rail 42；The tension spring 41
One end is fixedly connected by link block 44 with the telescopic block 2 43, and the other end is fixedly connected on activity by elasticity adjusting device 4
On clamping piece 12；The lower end of the telescopic block 2 43 offers and 42 matched sliding slot of sliding rail；It the telescopic block 1 and stretches
