Description
Technical field
The utility model relates to tool wrench, relates in particular to no gap and regulates adjustable wrench.
Background technology
The common adjustable wrench of prior art includes handle, fixed pliers head, moving jaw and worm and gear and forms; Its main characteristics is to regulate the width of jaw according to actual needs arbitrarily, is shaped as hexagon and tetragonal screw and nut with fastening various termination portion.But the adjustable wrench of prior art; Because the restriction of design and manufacture craft aspect, the gap of cooperation is bigger, in the process of using, can need often regulate because precision is low; Both influence the efficient of work, easily nut or the screw rod that turns caused damage again.
The utility model content
The purpose of the utility model is, overcomes the weak point of prior art, provides a kind of no gap to regulate adjustable wrench, and the moving lip that can guarantee spanner is in location, position arbitrarily, no free gap, and it is constant all the time to keep spanner to move the aperture that lip and spanner decide between the lip.
Adjustable wrench is regulated in the described no gap of the utility model, includes to decide lip, moving lip slide bar, slide bar tooth, spring, auxilliary worm gear, spanner handle, main worm gear, worm-wheel shaft, chute, moving lip, Worm Bearing, auxilliary worm-gear toothing, major-minor worm gear gap, major-minor worm-gear toothing engagement straight-tooth and main worm-gear toothing.Spanner handle is the handpiece of the utility model, and the front end of spanner handle is provided with decides lip, is provided with moving lip in a side of deciding lip; Front portion deciding the downward spanner handle of lip is provided with chute, and the lower end of moving lip is connected with moving lip slide bar; The downside of moving lip slide bar is provided with the slide bar tooth, and moving lip slide bar is arranged in the chute, in the spanner handle below chute; Be provided with worm-wheel shaft, penetrate worm-wheel shaft and be provided with main worm gear and auxilliary worm gear, main worm gear is provided with main worm-gear toothing; Auxilliary worm gear is provided with auxilliary worm-gear toothing, and main worm-gear toothing and auxilliary worm-gear toothing are meshed with the slide bar tooth.Outer end and the inner at worm-wheel shaft are provided with Worm Bearing, and main worm gear is in the outer end position setting of worm-wheel shaft; Auxilliary worm gear is in the inner end positions setting of worm-wheel shaft, and main worm gear adopts major-minor worm-gear toothing engagement straight-tooth to be connected with auxilliary worm gear, is connected between the end face what main worm gear was connected with auxilliary worm gear; Be provided with major-minor worm gear gap; The inner around worm-wheel shaft is provided with spring, and the spring top is located on the outer face of auxilliary worm gear.The adjusting worm gear of the utility model is divided into main worm gear and auxilliary worm gear two parts; Leave suitable gap between main worm gear and the auxilliary worm gear; Even when main worm-gear toothing and auxilliary worm-gear toothing clamping slide bar tooth; Still keep certain clearance between main worm gear and the auxilliary worm gear, and both are meshed together, make main worm gear and auxilliary worm gear keep rotating synchronously through straight-tooth.There is a spring the inner of auxilliary worm gear; Make auxilliary worm gear produce left a power, this power acts on the right side of slide bar tooth through auxilliary worm-gear toothing, forces moving lip slide bar to be moved to the left; And act on the main worm-gear toothing through the slide bar tooth; Therefore and eliminated the gap between main worm-gear toothing and the slide bar tooth, and make main worm gear receive power left and abut against on the Worm Bearing of left side, also just eliminated the gap between main worm gear and the left side bearing; Thereby thoroughly eliminated the moving lip of spanner and decided the free gap between the lip, realized that the no gap of spanner folding is regulated.In use, the moving lip of spanner can be located at an arbitrary position, no free gap, and keep its aperture constant all the time, make it and can compare U.S.A with fork spanner.This structure only changes the worm gear arrangement of regulating spanner folding, and other main part must not change, thereby has simplified processing technology.
Adjustable wrench is regulated in the described no gap of the utility model, and overall structure is simple, and is easy for operation, good stability, and reliability is high.Use the described no gap of the utility model to regulate adjustable wrench, the moving lip that can guarantee spanner is in location, position arbitrarily, no free gap, and it is constant all the time to keep spanner to move the aperture that lip and spanner decide between the lip.
