Description
Technical field
The utility model relates to a kind of tail screw rod governor motion and screw special structure thereof of locking pliers.
Background technology
Existing locking pliers, as shown in Figure 1, by the adjusting screw(rod)/screw 5 that is provided with in fixed handle 11 and flexible handle 12 places and the interaction of members such as extension spring 3 and push rod 4, realize adjusting to locking pliers fixed arm 21 and lever arm 22 presser feets 6 spacings, and head 51 positions at the tail screw rod are processed with straight knurling 511 or hatching knurling, and the design of this annular knurl also makes operating personnel more convenient laborsaving when turning screw rod 5 advance and retreat; But in actual mechanical process, after caliper is by fastening, the presser feet part has been in local painstaking state, so the clamping effect that wants to reach more fastening just must realize by the annular knurl of manual adjustment tail screw rod 5, and the dynamics that manual adjustment is bestowed is relatively limited, so the effect of this regulative mode is often also unsatisfactory; So people have expected adopting the spacing dimension of estimating or calculate two presser feets 6 in advance, after then screw rod 5 being screwed to the position that needs and locating by the extra additional stop nut 52 of institute on the screw rod 5, the mode of operation of pressing handle again, said method is much better relatively though it grips effect, but Cao Zuo mode still has many deficiencies like this: one comes the measuring and calculating trouble of presser feet 6 spacings and has error, two after clamping adjustment and to regulate be not easily, and its operating efficiency and effect neither be fine.
Existing locking pliers in use need unclamp presser feet earlier, just can regulate the tail screw, and then tighten up the locking pliers handle, if elasticity is improper, then needs repetition aforesaid operations program, and in adjustment process, workpiece tends to unclamp.
The utility model content
Technical problem to be solved in the utility model is to overcome the above-mentioned deficiency of existing locking pliers, and a kind of locking pliers tail screw rod governor motion that more helps presser feet to the workpiece clamping is provided.
Another technical problem to be solved in the utility model provides a kind of screw or screw rod that is exclusively used in above-mentioned tail screw rod governor motion.
In order to solve above technical problem, by the following technical solutions.
A kind of locking pliers tail screw rod governor motion comprises a tail screw rod, is provided with a rocking arm at the tail screw head, this rocking arm is used for strengthening the strength of adjustment that screw rod screws in or screws out, adjusting to screw rod is more put in place, help the realization of presser feet, improve service speed workpiece or the clamping of supporting surface appropriateness.
This rocking arm and tail screw head can be fixed as one.Also can be at the head processing cross-drilled hole of tail screw rod, cross-drilled hole is realized and the socket of tail screw head by rocking arm is passed.The design of its cross-drilled hole also helps selecting for use flexibly or loading and unloading dissimilar rocking arms, such as L type crank or linear pattern handlebar; Further, can be provided with turning set on this L type crank, being provided with of this turning set can make rotation more smooth and easy.
In addition, described rocking arm can be riveted on the adjustable handle of the tail screw head anglec of rotation for one, and the rotatable regulative mode of its angle makes the setting of this rocking arm be unlikely to because the restriction in space and being affected in the use.
Simultaneously, on the tail screw rod stop nut can also be set, rationally lock or selected tail screw rod needs the position of precession, be particularly useful for repeating to clamp or keep during batch process identical clamped condition.
A kind of screw or screw rod that is exclusively used in above-mentioned tail screw rod governor motion offers the jack that aperture and rocking arm profile adapt at screw (or screw rod) head, is beneficial to that rocking arm is assigned or painstakingly; This jack can be cross-drilled hole.Being arranged so that of this jack (or for cross-drilled hole) not only can be adopted the mode turn tail screw (or tail screw rod) that adds rocking arm in the hole simultaneously, and also can adopt instrument complete operation such as screwdriver temporarily.
Adopt the locking pliers tail screw rod governor motion and the special-purpose tail screw (tail screw rod) of this technical scheme, thereby can by the turnover of adjusting the tail screw rod presser feet be adjusted to the position of adaptation easily, realize fast advance and retreat and increase clamping force, and simple in structure, easy to operate.

The specific embodiment
Locking pliers tail screw rod governor motion as shown in Figures 2 and 3, be connected with the rocking arm that a L type crank 531 serves as the screw rod advance and retreat at screw head 51 places of screw rod 5, on this rocking arm, be provided with the turning set 5311 of a plastic material, make locking pliers in clamping process, the power that screw rod 5 is executed is more handy, help after the fastening of caliper handle the reasonable adjusting to presser feet 6 dynamics that acts on, it is easy to use flexibly.Can on screw head 51, offer cross-drilled hole 512 on the structure, the handle bar of this L type crank 531 is passed cross-drilled hole 512, making both appropriate sockets is one, between crank and cross-drilled hole, can fix by a tight loop 513, the function of this tight loop 513 also can substitute by welding or riveted way and realize, the rocking arm of different size requirement can be conveniently used in detachable design, such as this L type crank is replaced with linear pattern handlebar 532 represented among Fig. 4, make this rocking arm and screw rod 5 form a T type handle.
To shown in Figure 7, be another embodiment of the present utility model as Fig. 5, on screw head 51, rivet the turning handle 533 that an angle is rotatable and regulate by rivet 5331; This structural design makes so-called rocking arm be unlikely to influences operate as normal because of the restriction of usage space.
As shown in Figure 8,, offer jack 512B, be used for making things convenient for the grafting of rocking arm or painstaking at screw head for screw special of the present utility model/screw-rod structure schematic diagram.
This locking pliers tail screw rod governor motion is with respect to the effect that annular knurl is set merely in the prior art, and strength of adjustment is bigger, also time saving and energy saving in the operation, correspondingly improved operating efficiency and quality.
This mechanism has avoided the existing locking pliers situation that workpiece tends to become flexible in adjustment process to take place, carrying out constantly trace by the rocking arm (regulating the tail screw rod) of choosing the back regulates, usually workpiece need not down to unload, regulate on one side, can the armrest sense judge tightness on one side, reach the most satisfied effect.
