Abstract
The utility model belongs to the hand tool, in particular to a wrench with rapid adjustable mechanism. The utility model comprises a wrench handle, a regular jaw and a moving jaw, and is characterized in that: the wrench handle of the adjustable wrench is provided with an open slot, a columned screw rod contained in the open slot is inserted into a hole of one end of the slot, one end of the screw rod corresponding to the moving jaw is provided with a driving bevel gear meshed with a driven bevel gear on an adjustable screw rod connected with the moving jaw; an adjustable sliding block is inserted into a screw groove of the other end of the screw end, and is allowed to move up and down along the screw groove of the screw rod to drive the rotation of the screw rod, while the transmission arising from the mesh of the driving bevel gear and the driven bevel gear is used to realize the clamp and the release of the moving jaw. The bayonet size of the wrench can be freely increased or decreased by slightly pushing the adjustable sliding block, which allows the adjustment to be convenient and free, easy and quick.
Description
Technical field
The utility model belongs to hand tools, particularly a kind of adjustable wrench with quick adjustment mechanism.
Background technology
Spanner is as the hand tools that people use always, is used for tightening and unclamps various screws and nut.Spanner has multiple version, is broadly divided into general utility wrench and special spanner, and general utility wrench is applicable to that the screw of standard and nut use; Special spanner is applicable to that special-shaped screw and nut use.Be suitable for adjustable wrench the most widely in the common spanner, its spanner bayonet socket size is adjustable, its structure is: an end of adjustable wrench has one to be with spanner handle the spanner of angle bayonet socket is arranged, there are stationary jaw and movable jaw in spanner bayonet socket place, stationary jaw and spanner handle are made one, movable jaw is arranged in the movable jaw groove of spanner handle, also has the adjusting screw(rod) axle in the claw groove, rotating adjusting screw(rod) is arranged on the adjusting screw(rod) axle, the helical tooth of adjusting screw(rod) and the engagement of the regulating tooth on the movable jaw, when with hand adjustment joint screw rod, promote movable jaw and move, thus the size of regulating the monkey wrench bayonet socket.Yet, when saving screw rod with hand adjustment, the adjustable wrench of this structure relatively requires great effort, and operation is convenient inadequately and quick.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of adjustable wrench with quick adjustment mechanism is provided, and quick adjustment mechanism makes the adjusting of spanner bayonet socket convenient, quick, light.
For addressing the above problem, the technical solution of the utility model is: a kind of adjustable wrench with quick adjustment mechanism, it is by spanner handle, stationary jaw and movable jaw, it is characterized in that: the opening elongated slot is set on the spanner handle of adjustable wrench, contain the cylindrical screw rod put in the elongated slot and insert in the hole of elongated slot one end, install master bevel gear on the screw rod of corresponding movable jaw one end, and with adjusting screw(rod) that movable jaw is connected on be meshed by bevel gear; Insert perfume (or spice) in the helicla flute of the screw rod other end and answer adjusting slider, its adjusting slider is moved up and down along the helicla flute of screw rod, and when driving the screw rod rotation by the master, by the bevel gear engaged transmission, realize the chucking of movable jaw and unclamp.
The back-end device snap ring of device master bevel gear on the described screw rod.
Described elongated slot surface is by the fastening cover plate of screw.
One end of described adjusting slider has the spring of eliminating the gap, and the other end has the screw of support stifled.
The afterbody of described spanner handle is provided with polygonal driving hole commonly used.
The beneficial effects of the utility model are: touch moving adjusting slider, can arbitrarily increase or reduce spanner bayonet socket size, make freely easy to adjust, easily quick.
Description of drawings
Fig. 1 partly cut-away of the present utility model structural representation.
Fig. 2 A of the present utility model is to view.
Among the figure: 1 spring, 2 adjusting screw(rod)s, 3 snap rings, 4 screw rods, 5 cover plates, 6 screws, 7 spanner handles, 8 movable jaws, 9 screws are stifled, 10 master bevel gears, 11 adjusting sliders, 12 stationary jaws, 13 by bevel gear, 14 polygonal driving holes.
The specific embodiment
Specify the utility model below in conjunction with drawings and Examples.
As shown in the figure: a kind of adjustable wrench with quick adjustment mechanism, spanner handle 7 is provided with the opening elongated slot, have the cylindrical screw rod 4 of spiral fluted in the elongated slot, screw rod 4 inserts in the hole of elongated slot one end, snap ring 3 is arranged on the screw rod of elongated slot opposite side, snap ring is axially fixing in elongated slot with screw rod, the adjusting slider 11 that can slide in elongated slot is arranged in the elongated slot, insert screw rod 4 in the threaded hole on the adjusting slider, when promoting adjusting slider 11, adjusting slider is along moving up and down in the elongated slot of spanner handle, the threaded hole of adjusting slider is by the helicla flute of screw rod, make the screw rod rotation, the spiral fluted lift angle is very little, and the motive force of adjusting slider is less.According to the operation principle on inclined-plane, make screw rod produce bigger revolving force, it is free and relaxed that screw rod is rotated.Otherwise helicla flute can produce self-locking, and the revolving force of screw rod is difficult to make adjusting slider to move.The movable jaw of spanner in use can not become flexible like this.The other end of screw rod 4 has being meshed by bevel gear 13 on master bevel gear 10 and the adjusting screw(rod) 2, and adjusting screw(rod) can rotate under the support of hole on the spanner handle and screw stifled 9, the tooth engagement on helical tooth on the adjusting screw(rod) 2 and the movable jaw 8.When adjusting screw(rod) rotates, promote movable jaw and move, thus the size of change spanner bayonet socket.Adjusting screw(rod) one end that is connected with stationary jaw 12 has spring 1, and spring is used for eliminating the gap between the helical tooth of the tooth of movable jaw and adjusting screw(rod).Cover plate 5 is arranged on the elongated slot of spanner handle 7, and screw 6 is fastened on cover plate on the spanner handle, moves in the slotted hole of adjusting slider 11 on cover plate 5.The afterbody of spanner handle 7 is provided with polygonal driving hole 14 commonly used.
Operation principle is: when promoting adjusting slider, adjusting slider moves along the elongated slot of spanner handle, spiral slotted eye in the adjusting slider makes the screw rod rotation by the helicla flute of screw rod, the master bevel gear of screw rod end makes the adjusting screw(rod) with its engagement be rotated by bevel gear, thereby adjusting screw(rod) is rotated.The helical tooth of adjusting screw(rod) promotes the regulating tooth of movable jaw, and movable jaw is moved, thereby changes the bayonet socket size of spanner.
Claims (5)
1, a kind of adjustable wrench with quick adjustment mechanism, it is by spanner handle, stationary jaw and movable jaw, it is characterized in that: the opening elongated slot is set on the spanner handle of adjustable wrench, containing the cylindrical screw rod of putting in the elongated slot inserts in the hole of elongated slot one end, install master bevel gear on the screw rod of corresponding movable jaw one end, and with adjusting screw(rod) that movable jaw is connected on be meshed by bevel gear; Insert corresponding adjusting slider in the helicla flute of the screw rod other end, its adjusting slider moved up and down along the helicla flute of screw rod, and when driving the screw rod rotation by the master, by the bevel gear engaged transmission, realize the chucking of movable jaw and unclamp.
