Checknut assembly also comprises front jaw element 61 and deutomala element 62, front jaw element 61 is from the front end of screw rod to downward-extension, front jaw portion 611 is arranged on inside lower extension, deutomala element is movably arranged on screw rod by upper end portion 621, the inner side of bottom has deutomala portion 622, deutomala portion is relative with front jaw portion, uses and holding articles.The upper end portion of deutomala element has a middle through hole 622, is enclosed within screw rod 11b.First ring-type element 21b is arranged on the side of deutomala element upper end portion 621, the top of deutomala element also has a folder portion 623 of protruding, first ring-type element 21b and the second ring-type element are arranged between deutomala element upper end portion 621 and the folder portion 623 of protruding, by rotating the first ring-type element, first ring-type element seesaws along screw rod, thus promotion deutomala element seesaws, the distance namely before adjustment between jaw portion and deutomala portion, reaches the effect of holding articles.The opposite side that the deutomala portion of deutomala element is relative has a handle 624.
In using, under normal circumstances, tooth and the screw flight of the second ring-type element do not contact and maybe can not produce very large frictional force, can not impact the motion of screw rod in the first ring-type element, when screw rod is relative with the first ring-type element position fix time, when screw rod receive external force tilt state under, the tooth on the second ring-type element provides extra frictional force to screw rod, screw rod can not be slided along the first ring-type element, thus keep stationary state.
In the present invention the 4th embodiment, as Figure 10, shown in 11 and 12, checknut assembly is specially double ended wrench, and screw member is inner screw member 21c, inside has internal thread, can match with the outside thread of outside thread element, and move with outside thread elements relative, particularly, inner screw member is only positioned at the both sides of outside thread element, middle exposed portion outside thread element.Barrier element 3 is arranged on the outside of inner screw member 21c, fixes with screw member.Outside thread element comprises screw rod 11c, and screw rod can along inner screw member side-to-side movement.
Barrier element 3 comprises the outside that the second ring-type element 32c is arranged on inner screw member, second ring-type element has the through hole that inside can hold inner screw member and outside thread element, inner screw member can be held and screw rod extends there through, the inner side of through hole has projection, be specially spaced tooth bar 34c, be positioned on inner corresponding to the exposed outside thread position of the second ring-type element.The position that second ring-type element is corresponding to screw member have upper through hole 351 and lower through-hole 352, be separately positioned on the position, the upper side and lower side of the second ring-type element, connecting element can be used to be fixed by upper lower through-hole and inner screw member, like this, the second ring-type element can be fixed on the outside of inner screw member.
Checknut assembly also comprises the Wrench head being separately positioned on inner screw member both sides, the first Wrench head 71 and the second Wrench head 72.The shape of head can be the same or different, and also comprises the movement rod corresponding to Wrench head, the first movement rod 73 namely coordinated with the first Wrench head, and the second movement rod 74 coordinated with the second Wrench head.First movement rod is positioned at the inside of inner screw member, and one end is connected with one end of outside thread element, and the other end and the first Wrench head form the cavity of alterable size, for the nut be applicable to, as large six-sided nut.Second movement rod is positioned at the inside of inner screw member, and one end is connected with the other end of outside thread element, and the other end and the second Wrench head form the cavity of alterable size, for the nut be applicable to, as little six-sided nut.When screw rod moves in inner screw member time, as during to left movement, the cavity of the first Wrench head diminishes, and when moving right, the cavity of the second Wrench head diminishes, thus regulates with service condition.Particularly, outside thread element, namely the both sides of screw rod have hole, can hold the outstanding joint 75 and 76 of the first movement rod and the second movement rod respectively, thus be fixedly connected with.
In using, under normal circumstances, tooth and the screw flight of the second ring-type element do not contact and maybe can not produce very large frictional force, can not impact the motion of screw rod in inner screw member, when screw rod is relative with inner screw member position fix time, when screw rod receive external force tilt state under, the tooth on the second ring-type element provides extra frictional force to screw rod, screw rod can not be slided along the first ring-type element, thus keep stationary state.
In the present invention the 5th embodiment, as shown in Figs. 13 and 14, checknut assembly is specially spanner, screw member 2d side has screw thread, can match with the outside thread of outside thread element, and move with outside thread elements relative, particularly, screw member is only positioned at the side of outside thread element, and the outside thread of the remaining part of outside thread element is exposed.Barrier element 3 is arranged on the outside of screw member, is specially the opposition side of the relative outside thread element of screw member.Outside thread element comprises screw rod 11d, and screw member 2d can along screw rod side-to-side movement.
Barrier element specifically comprises the tooth block 33d of the opposition side being arranged on the relative outside thread element of screw member, and the inner side of tooth block has projection, comprises spaced tooth bar 34d, is positioned on the position corresponding to exposed outside thread.
Checknut assembly specifically also comprises handle 81, and have the side through hole 82 for installing screw rod above handle, the both sides of screw rod are arranged on the both sides of side through hole, and externally threaded sidepiece can expose at side through hole place, moves screw rod for hand-screw.The top of side through hole also has a cell body 83 upwards, and screw member is arranged in cell body.The bottom of cell body communicates with side through hole, and the screw thread of screw member is positioned at the bottom of screw member, is engaged mutually, thus can moves along outside thread with the outside thread on the outside thread element being positioned at side through hole.Inner screw member top is also extended with mobile jaw 84, can move left and right with screw member.Also fixed jaw 85 is upwards extended with in the side of cell body, relative with mobile jaw, and can holding articles.Tooth block is placed in the teeth groove 86 of side through hole bottom.
In using, under normal circumstances, tooth on tooth block does not contact with the outside thread of screw rod maybe can not produce very large frictional force, can not impact screw rod and screw member relative movement, when screw rod is relative with screw member position fix time, when screw rod receive external force tilt state under, the tooth on tooth block provides extra frictional force to screw rod, screw rod threadingly can not be slided by element, thus keep stationary state.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design according to the present invention can make many modifications and variations without the need to creative work.Therefore, all technician in the art, all should by the determined protection domain of claims under this invention's idea on the basis of existing technology by the available technological scheme of logical analysis, reasoning, or a limited experiment.
