Plate is connected by fastening bolt, and the pad being enclosed in fastening bolt is provided between fingertip and corresponding transverse slat, and fastening bolt is inserted
In the second stopper slot, two adjustment holes are provided with upper and lower two pieces of transverse slats, are provided with regulating block in adjustment hole, regulating block with
Adjustment hole contact of incline plane, there is the guide frame that guide adjustment block slides up and down on the inclined-plane of adjustment hole, regulation on adjustment hole
It is fixed with draw ring on block, draw ring is located at the outside of corresponding transverse slat, and the both sides of two transverse slats and two fingertips respectively pass through a double end
Bolt connection, stud are through in the first stopper slot of the adjustment hole of transverse slat, the annular distance of draw ring and fingertip, and the two of stud
End is connected with nut, and the spring for being provided with compression of each nut and draw ring, spring housing is on stud, the freedom of each transverse slat
End is against on one end of main body plate benging, is threaded with screw between regulating block and transverse slat, screw axis and stud
Diameter parallel, the hole that mounting screw is used on regulating block is the screwed hole of up/down perforation regulating block, when regulating block is along adjustment hole
When inclined-plane slides into a certain position upwards, draw ring pulls stud to deviate from the first stopper slot.
In order to preferably push down fingertip, the free end of described upper cross plate is bent downwardly, the free end of described lower cross plate
It is bent upwards.
Static contact is pressed into for the ease of moving contact, the distance of the straight one end of the first described stopper slot away from main board is not
/ 3rd of the distance for passing through the vertical plane at main board both ends more than main board.
Slided up and down for the ease of regulating block on the inclined-plane of adjustment hole, described adjustment hole is that axial cross section is terraced for right angle
The hole of shape, described guide frame are the side wall of the both sides on the inclined-plane on adjustment hole.
The beneficial effects of the invention are as follows：The fingertip of the present invention and contact supporting are clamping, that is, can guarantee that fingertip and contact branch
Frame connection is reliable, causes fingertip in dismounting without being folded down the spring for extruding fingertip again, so as to prevent spring from ejecting.
When dismantling fingertip, rotary screw makes screw depart from transverse slat, and head of screw stretches out from regulating block, hauls screw and adjusts regulating block edge
The inclined-plane in hole pulls up, and draw ring is mobile with regulating block and departs from corresponding transverse slat so that spring is to the distress resolves of transverse slat, just
Depart from the first stopper slot in stud, and transverse slat is reduced to the pressure of fingertip, after unclamping fastening bolt, you can use pliers
Fingertip is clamped to take out fingertip from contact supporting.
