There is sliding block 3 through 2 sliding connection of two slide bars in the U-shaped inslot of U-shaped base 1, two slide bars 2 are parallel to each other and are in the coplanar (for example vertical plane or horizontal plane, place the corresponding plane of angle correspondence according to the difference of tool), the cover is equipped with spring 4 respectively on every slide bar 2, spring 4's one end acts on a cell wall in U-shaped groove, spring 4's the other end acts on the terminal surface of 3 thickness directions of sliding block, and another terminal surface of 3 thickness directions of sliding block and another cell wall in U-shaped groove form the centre gripping space.

Be equipped with protruding muscle 10 at a tip of U-shaped base 1, and protruding muscle 10 has the first centre gripping convex part 11 that stretches into in the centre gripping space, the free end of first centre gripping convex part 11 has the clamping face (can change according to the product), it grips muscle 30 to be equipped with the protruding muscle of gripping that is relative distribution with protruding muscle 10 on sliding block 3, protruding muscle 10 and protruding muscle 30 of gripping all are the strip cubic, and protruding muscle 10 and protruding muscle 30 of gripping are located same straight line, protruding muscle 30 of gripping is used for gripping of operator, and protruding muscle 30 of gripping has the second centre gripping convex part 31 that stretches into in the centre gripping space, the free end of second centre gripping convex part 31 has the clamping face, first centre gripping convex part 11 and second centre gripping convex part 31 are relative distribution, and first centre gripping convex part 11 and second centre gripping convex part 31 distribute in the position between two slide bars 2.

The configuration of two slide bars 2 to and the sliding fit of sliding block 3 and two slide bars 2, can make sliding block 3 slide smoothly, distribute in the design of first centre gripping convex part 11 and the second centre gripping convex part 31 of two slide bars 2 central positions in coordination, can prevent that the deformation of sliding block 3 from and leading to the counterpoint precision decline of first centre gripping convex part 11 and second centre gripping convex part 31, promptly, can ensure the counterpoint precision, thereby guarantee to detect the precision.

Preferably, the springs 4 of this embodiment are of equal length and have the same spring force. The spring 4 is commercially available directly.

Secondly, two guide holes 32 are formed in the sliding block 3, two ends of the U-shaped base 1 are respectively provided with a sliding rod fixing hole 12, the two sliding rods 2 penetrate through the corresponding guide holes 32 one by one, two ends of the two sliding rods 2 are fixed in the corresponding sliding rod fixing holes 12 one by one, and the sliding rod fixing holes 12 are through holes. The above structure facilitates the installation of the slide bar 2 and the slide block 3.

As shown in fig. 2, a gap is left between a surface of the slide block 3 near the bottom of the U-shaped groove and the bottom of the U-shaped groove. So as to prevent the interference of sliding operation.

In order to prevent the clamping surfaces from colliding with each other, a damping rubber column 5 is arranged on one groove wall of the U-shaped groove, the free end of the damping rubber column 5 faces the sliding block 3, and the free end face of the damping rubber column 5 exceeds the clamping end face of the first clamping convex part 11.
