As shown in Figure 1, a kind of machine for tensile strength testing clamping device, the folder including a pedestal 2 and setting on the base 2
Tool and pull rod 1, pedestal 2, which is opened, is formed with a mounting groove 21, and the opening of mounting groove 21 is arranged in fixture, and pull rod 1 is arranged in mounting groove 21
Slot bottom；Fixture includes two fixture blocks 5 being oppositely arranged and a connecting rod 3, and one end of connecting rod 3 and pull rod 1 are pivotally connected, connecting rod
3 other end and two fixture blocks 5 are clamped；21 slot bottom of mounting groove is fixed with a fixing seat, and the middle part of pull rod 1 and fixing seat are pivotally connected shape
At a fulcrum；A spring 4 is arranged in connecting rod 3；Pedestal 2 is provided in the other side of 21 slot bottom of mounting groove and connect with testing machine
Connector 8, connector 8 is inserted with a fixed link 81.
Connecting rod 3 is in T font, and two fixture blocks 5 open two link slots 52 for being formed with and communicating respectively, and two link slots 52 form
With the connecting cavity of 3 cross bar 31 of connecting rod clamping.
Fixture block 5 is provided with a convex block 51 toward 21 inner wall direction of mounting groove close to one end of pull rod 1, and mounting groove 21 is close to opening
Block 6 is provided on the inner wall at place, the convex block 51 of fixture block 5 is resisted against 6 side of block under the action of spring 4.
The distance of 21 two sides inner wall of mounting groove is sequentially increased from being open toward slot bottom direction.
Vertical range between two fixture blocks 5 is 0-7mm.There is a little spring 4 between two fixture blocks 5.
Fixing seat is made of the fixed block 7 that 1 two sides of pull rod are arranged in, and is vertically installed with a shaft between two fixed blocks 7
9, the middle part of pull rod 1 is provided with a through-hole, and shaft 9, which is threaded through in through-hole, forms fulcrum.
Pull rod 1 can stretch down, so that black binding clasp is opened.
Fixture can effectively clamp measured object and make measured object not easily to fall off.Pedestal 2 is fixed on by fixed link 81
On testing machine.Pull rod 1 is connect by connecting rod 3 and spring 4 with fixture, when pull rod 1 is pulled toward fixture direction, two fixture blocks 5
It is pulled toward slot bottom direction, because the distance of slot bottom two sidewalls is larger, so that two fixture blocks 5 are opened under the action of little spring 4；Work as drawing
When bar 1 is pulled toward the direction of connector 8, pull rod 1 will push connecting rod 3 to push two fixture blocks 5 toward the opening of mounting groove 21
Direction is mobile, because the inner wall distance of opening two sides is gradually smaller, so that the distance between two fixture blocks 5 gradually become smaller, from
And clamp the tested sample between two fixture blocks 5, because pull rod 1 is remote with the length of position to fulcrum that connecting rod 3 is pivotally connected
Much smaller than the length of 3 other end of connecting rod, so that two fixture blocks 5 need very big power that could separate two when clamping tested sample
A fixture block 5, to guarantee that tested sample can be firmly clamped between two fixture blocks 5.
Do not limit the technical scope of the present invention above, it is all according to the utility model technical spirit to
On embodiment made by any modification, equivalent variations and modification, in the range of still falling within the technical solution of the utility model.
