fig1 shows an assembled tool accessory 10 comprising a left leg or first leg 12 and a right leg or second leg 14 . the left leg and the right leg 14 are pivotally connected with each other and biased via a lock 16 . the left leg 12 is snapped - in to the right leg 14 via an opened arcuate socket 12 h connecting with an arcuate pivot shaft 14 y . fig5 shows the left leg 12 comprising an elongated body 12 a . the body 12 a comprises a pair of clamping jaws 12 b at one end and a pair of forks 12 g separated by a space 12 i . the elongated optionally contains a series of weight reducers 12 j and a stress hole 12 f . the stress hole 12 f is continuous with a slot 12 e formed in the left leg 12 thus allowing the jaws 12 b to flex outwardly and accommodate different diameter probes . the pair of jaws 12 b are separated by a slot 12 c blending with a probe opening 12 d . the slot 12 c allows an electrical cable that runs from a multimeter probe to be inserted so that the probe can slide in the probe opening 12 d . features 12 a - 12 f and 12 j found in the left leg 12 should be noted to be present in the right leg 14 thus making the legs 12 , 14 partially symmetrical , see fig6 . fig5 further shows the pair of forks 12 g containing each the opened arcuate socket 12 h forming an arc greater than 180 degrees and less than 270 degrees to provide a snap - in pivotable connection with . the left leg 12 has a pair of parallel side edges 12 l that are coaxial with a pair of parallel edges 14 l in the right leg 14 . fig4 shows the lock 16 comprising a holder 16 a , a first section 16 b , a second section 16 c and a third section 16 d . the holder 16 a allows a user to slide the lock 16 and the holder 16 a is continuous with the first section 16 b . the first section 16 b contains at least one planar surface 16 g which prevents the left leg 12 and the right leg 14 to pivot outwardly thus keeping the legs 12 , 14 parallel to each other . the second section 16 c comprising at least one tapered surface 16 m that tapers from the first section 16 b to the third section 16 d . the taper surface 16 m is narrow at the third section 16 d . an elongated shaft opening 16 h runs from the second section 16 c to the third section 16 d . the elongated shaft opening 16 h is delimited by a pair of opposed walls of which one contains a series of spaced lock projections 16 i which set the lock 16 at different fixed positions when sliding . the shaft opening 16 h is continuous with a slot 16 j which in turn the slot 16 j is continuous with a gap 16 p formed by the spring legs 16 e , 16 f . a pair of opposed leaf springs 16 e , 16 f continuously project from the third section 16 d at an angle relative to the longitudinal axis of the lock 16 . the leaf springs 16 e , 16 f each form a recess 16 k having a depth relative to the outer wall of the third portion 16 d . the recess 16 k provides a relief to the leaf springs 16 e , 16 f when bent . the holder 16 a has an opening 16 n and sized to be bigger than the space defined between the main bodies of the left leg 12 and the right leg 14 . it should be noted that the term “ continuos ” or “ continuously ” is defined as being homogenous and not a separate entity . fig6 and 7 show the right leg 14 containing a pair of arms 14 x integrally holding the arcuate pivot shaft 14 y that snaps in with the arcuate socket 12 h of the left leg 12 and forms an arcuate angle of 270 degrees or greater . the pair of arms 14 x are separated by a space 14 z which allows the leaf spring 16 e or leaf spring 16 f to be slid until the pivot shaft 14 y penetrates into the sliding opening 16 h via the slot 16 j . the sliding opening 16 h is dimensioned to allow the pivot shaft 14 to slide while overcoming the lock projection 16 i . the sliding opening 16 h is delimited by at least one stopper 16 l so that the lock 16 is prevented from sliding out of the pivot shaft 14 y especially when the left leg 12 and the right leg 14 are detached from each other . the leaf springs 16 e , 16 f bias both the right leg 12 and the left leg 14 outwardly . the outward motion of the legs 12 , 14 is limited when the edge 12 k or the edge 14 k touches the tapered surface 16 m as shown in fig3 a . the range of outward motion is determined by the position at which the lock 16 is placed . when the lock 16 is pushed in all the way as shown in fig3 b , the legs 12 , 14 are prevented from pivoting outwardly as the edges 12 k , 14 k are stopped by at least one of the planar surfaces 16 g or both planar surfaces 16 g . it should be noted that the tool accessory 10 can be made from any known material . in particular , the ideal material would be a flexible material so that the leaf springs 16 e , 16 f provide flexibility , repeatability , and a biasing force . further , as seen in fig8 and 9 , the left leg 14 ′ and the right leg 14 ′ could be made hermaphroditic having each an arcuate socket 12 h and a pivot shaft 14 y ′ which respectively snap in with the shaft 14 y ′ and the socket 12 h of the other leg . the legs 14 ′ would also contain a fork 12 g , an arm 14 x ′, and an l - shaped gap 14 z ′. the arm 14 x ′ holds a pivot shaft 14 y ′ so that when the legs 14 ′ are joined , the pivot shaft 14 y ′ of one leg 14 ′ would be coaxial to that of the other leg and snapping in with the corresponding fork 12 g . in the modified legs 14 ′ shown in fig8 , the edges 14 k ′ would be stopped by the tapered surface 16 m of the lock 16 thus defining the range of outward motion of the legs 14 ′ or prevent outward motion by the planar surface 16 g of the lock 16 . other modifications would be apparent . the snap - in pivot connection disclosed could as well be replaced with offset forks in both legs and held together with a separable pivot shaft inserted in arcuate sockets or holes . the pivot shaft 14 y , 14 y ′ could as well be made shorter so that the lock 16 is not held on the pivot shaft thus not requiring lock projections 16 i . the probe opening 12 d , the stress hole 12 f , and clamping jaws can be made from any other known shape . the body 12 a although being rectangular could as well be modified to any other shape . although the probe opening 12 d extends along the axis 20 at an angle relative to the longitudinal axis of the body of the legs as shown in fig2 , the probe opening can extend at any angle or parallel to the longitudinal axis of the legs 12 , 14 . further , the gaps 14 z , 14 z ′ could as well be formed by a mold projection extending through an opening , not shown , in the body 12 a of the right leg 14 , 14 ′.
