Embodiment
With reference to the accompanying drawings and detailed description, the present invention is furture elucidated, it should be understood that following embodiments are only
For illustrating the present invention rather than limitation the scope of the present invention.It should be noted that the word " preceding " used below in description,
" rear ", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outer " refer respectively to direction or remote
From the direction of particular elements geometric center.
As illustrated, a kind of concrete prefabricated piping lane Special ground tackle core caliper brake fastener of the present invention, including
Pressing handle 1,22, two pieces of supports 3 of pressing handle and four sliding blocks, the support are " convex " type, and support is provided with symmetrical
Two horizontal strip holes 4, two connecting holes 5 are provided between described two strip holes 4, and the height of connecting hole 5 is higher than the height of strip hole 4
Degree, the lower section of pressing handle 1 are arranged between two pieces of supports 3, and pressing handle 1 is connected with support in left connection hole, is compressed
The lower section of handle 22 sets eccentric block 6, and the eccentric block 6 is arranged on two pieces of stent outers, and pressing handle 22 is with support 3 in right company
Connecing and connected at hole, four sliding blocks are divided into 8 two groups of sliding block A7 and slide block B, and sliding block A7 is arranged on two pieces of inside lefts of support 3,
