In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a multi-functional joint dipperstick, includes the pivot, the surface slip cover of pivot is equipped with the calibrated scale, the surface of pivot is close to the equal slip cover in the upper and lower place of calibrated scale and is equipped with the scale, the scale is provided with two altogether, and the both sides that the top of two scales is close to the pivot have all seted up the viewing aperture.

Preferably, two both sides that the bottom of scale is close to the pivot are all slided and are inlayed and be equipped with the sliding ball, and the bottom of sliding ball is slided with the top of calibrated scale and is inlayed and establish.

Preferably, the both sides of pivot all are equipped with the hollow cylinder lid, the both sides surface of pivot is close to both ends edge respectively and has all seted up the block groove.

Preferably, elastic plates are welded on the outer surfaces of the two sides of the hollow cylindrical cover.

Preferably, the center of the outer surface of one side of the elastic plate is welded with a clamping block, and the outer surface of the clamping block is connected with the inner surface wall of the clamping groove in a clamping manner.

The utility model provides a multifunctional joint measuring scale. The method has the following beneficial effects:

(1) this multi-functional joint dipperstick through the slip of sliding bead, when rotating the scale, can effectual reduction frictional force for the scale can be more convenient when rotating, and the scale mark is fallen in the preventing wear, and the worker of being convenient for observes.

(2) This multi-functional joint dipperstick, establish the both ends at the pivot through covering the hollow cylinder lid, make the block be connected with block groove block, elasticity through the elastic plate, make block more firm with block groove block, thereby the countershaft that can be better fixes, when changing the scale that damages, pull out the hollow cylinder lid, thereby can dismantle the hollow cylinder lid in the pivot, thereby can be better change the solitary scale to the damage, the cost of change that reduces that can be very big on using, convenient to use.
