Abstract

The utility model discloses a tube clamp which can make the rapid opening-closing of the adjustable jaws with single hand operation, which comprises a fixed jaw, an adjustable jaw and a clamp handle and is characterized in that the fixed jaw is linked and combined with the one end gap of the clamp handle. The adjustable jaw is fixed on one slider which is kinetically fitted over the clamp handle. The lower end of a trigger extended into the cavity of the lower side of the slider is fixed with the gear blocks meshed with the indentations on the clamp handle. A pressure spring is arranged between the upper end of the trigger and the slider upper end. The tube clamp above is not only with very simple structure, but also the manipulability of the utility model is greatly enhanced.

Description

A kind of fast pipe twist

Technical field

The utility model relates to a kind of pipe vice.

Background technology

Traditional pipe vice is formed by parts such as regular jaw, moving jaw, pincers handle, nuts, and regular jaw is fixed together its structure more complicated with the pincers handle.During use, need both hands to cooperate, rely on the transmission of the screw thread pair between nut and the moving jaw to realize the folding of jaw, it is very inconvenient to operate; Simultaneously, the speed of traditional pipe vice jaw folding also is subjected to the restriction of screw thread pair pitch, can't realize the quickly opening and closing of jaw.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of and can make moving jaw quickly opening and closing, and pipe vice that can one-handed performance.

For solving above-mentioned technical problem, the technical solution adopted in the utility model is: described fast pipe twist, comprise: regular jaw, moving jaw and pincers handle, be characterized in: regular jaw is connected with a splaying of pincers handle, moving jaw is fixed on the slide block, the slide block movable set is on the pincers handle, the lower end of trigger extend in the cavity of slide block downside, and the lower end of trigger is fixed with the tooth piece, the tooth piece is meshing with each other with the groove that clamps on the handle, is provided with stage clip between the upper end of trigger and the upper end of slide block.

Connected mode between said fixing jaw and the pincers handle is: regular jaw flexibly connects by rivet and pincers handle, is provided with the gap between the end of regular jaw and pincers handle, and is provided with the damping stage clip between the end of regular jaw and pincers handle.

The other end at above-mentioned pincers handle also is fixed with the toggle of shaking hands.

The beneficial effects of the utility model are: because the structure that adopts tooth bar and trigger to match has replaced original screw thread pair and heavy match mechanism thereof, not only structure is very simple, but and only need singlehanded with regard to flexible operating, can make slide block be provided with fast moving on the pincers handle of groove, thereby improved the folding speed of moving jaw greatly, that has also improved pipe vice greatly can be handling.

Fig. 2 is the cross-sectional view of pipe vice shown in Figure 1.

Fig. 3 is the perspective view of pipe vice shown in Figure 1.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing, but the utility model should not only limit to this embodiment.

As Fig. 1, Fig. 2, shown in Figure 3, described fast pipe twist comprises: regular jaw 1, trigger 2, slide block 3, pincers handle 4, moving jaw 5, the toggle 6 of shaking hands, damping stage clip 7 and stage clip 8; Regular jaw 1 is connected by the splaying of rivet 10 with pincers handle 4, and is provided with damping stage clip 7 between the end of regular jaw 1 and pincers handle 4; Moving jaw 5 is fixed on the slide block 3, slide block 3 movable sets are on pincers handle 4, trigger 2 also is sleeved on the pincers handle 4, the lower end of trigger 2 extend in the cavity of slide block 3 downsides, and the lower end of trigger 2 is fixed with tooth piece 11, tooth piece 11 is meshing with each other with the groove 9 that clamps on the handle 4, is provided with stage clip 8 between the upper end of the upper end of trigger 2 and slide block 3; The other end of pincers handle 4 also is fixed with the toggle 6 of shaking hands.During use, press trigger 2 earlier, the tooth piece that is attached thereto 11 breaks away from the obstruction of groove 9 on the pincers handle 4 that is engaged with, and makes slide block 3 to be free to slide on pincers handle 4, thereby drives moving jaw 5 fast moving, realizes opening fast or the purpose of closed jaw.After jaw is opened, the jaw of opening can be aimed at the object of the clamping of wanting, promote slide block 3 then, make moving jaw 5 and regular jaw 1 be adjacent to the object of clamping, decontrol trigger 2 again, trigger 2 resets under the effect of stage clip 8, thereby make groove 9 engagements on tooth piece 11 and the pincers handle 4, slide block 3 just is locked on the pincers handle 4, and the relative position between moving jaw 5 and the regular jaw 1 has also just locked, and then pulls the object that pincers handle 4 just can be pulled clamping; In use, owing to be provided with fit clearance between the end of regular jaw 1 and pincers handle 4, by this fit clearance, regular jaw 1 around being installed, rivet 10 is turned an angle, better meet object plane thereby can make to form between regular jaw 1 and the moving jaw 5, improved the ability of jaw clamping object greatly.
