Abstract
The utility model discloses an improved multifunctional fast acting clamping wrench. A wrench body 3 is provided with an internal cavity in which a fast clamping mechanism and a ratchet control mechanism are arranged, wherein the fast clamping mechanism comprises a button, a steel cable, a pulley, a spring, a screw, and a clamping jaw; the ratchet control mechanism comprises a ratchet, a pawl, a handle, the spring, a steel ball, etc. The quick clamping or releasing of a work object is realized through the wrench only by pushing the button when the wrench is used. The utility model has the advantages of no loosing, good clamping effect, and large applicable range.
Description
The utility model is a kind of improved many with clamping spanner fast.
Known is commercially available by wrench body, the spanner structure that screw rod and jaw are formed is fairly simple, use also more convenient, but when using except that needs continuously directly the turn screw rod, also there are two defectives, the one, the clamping effect is bad, and is loosening easily, the one, it is narrower to be suitable for magnitude range, and running into bigger nut just needs to have changed the large size spanner.
The purpose of this utility model provides a kind of binding nut fast, clamps the bigger many usefulness of magnitude range effective and suitable nut and clamps spanner fast.
Improvement project of the present utility model is, shown in accompanying drawing 1～2, many with clamping spanner fast, has wrench body (3), screw rod (2) and two jaws (1), jaw (1) is threaded with two ends of screw rod (2) respectively, this in addition spanner also has a push button (12) that is had screw (24) by its bottom surface, steel wire rope (14) pulley (21), pulley (9), law spring (4) reaches by wheel seat (8) with the quick clamping mechanism that above-mentioned screw rod (2) and jaw (1) are formed, ratchet (6), ratchet (17), dial handle (11), spring (15), the ratchet controlling organization that steel ball (16) is formed, above-mentioned wrench body (3) is designed to a housing with internal cavities, have hole (25) therebetween on the housing, the hand push mask of the push button of above-mentioned quick clamping mechanism (12) has the class that can strengthen frictional resistance, the bottom screw (24) of push button (12) is positioned at hole (25), pulley (21) is fixed on the other end of wrench body (3) inner chamber towards jaw (1) one end by its wheel shaft (20), pulley (9) is fixed on wrench body (5) inner chamber jaw (1) and screw rod top by its wheel shaft (10), steel wire rope (14) one ends and screw (24) are affixed, and the other end is connected with screw rod (2) with pulley (9) around pulley (21) successively; Like this, only need promote push button (12) during use, screw (24) on the push button (12) displacement event thereupon can drive steel wire rope (14) mobile and drive screw rod (2) rotation affixed with screw (24), screw rod (2) can axial two sides of worm drive screw shaft two jaws (1) move to the both sides, center simultaneously separately and open jaw (1), pincers unclamp push button (12) after going into target, screw rod (2) resets under the effect of law spring (4), jaw (1) thus move towards the center and can clamp the target nut quickly, make two jaws (1) loosening in order to guarantee the clamping effect.The ratchet of above-mentioned ratchet controlling organization (6) is installed on the axle of wrench body (3) inner chamber screw rod (2), law spring (4) then is installed between screw rod (2) bar axle and ratchet (6) wheel disc, ratchet (17) upper end is hinged on wrench body (3) by rivet (23) and goes up and have the handle (11) of dialling in addition, is provided with between lower end and the wrench body (3) to keep having between ratchet (6) and the ratchet (17) spring (15) of good engagement state and the elastic force detent mechanism of steel ball (16) composition.When ratchet (1) is driven by ratchet (6) and during deflection, ratchet (17) caught under the effect of spring (15) by steel ball (16) thereby concave surface makes ratchet (17) catch ratchet (6) that ratchet (6) must not be turned round, it is no longer loose that this just makes ratchet (17) fixedly positioning.Again because jaw (1) is so that two tool independent jaw sheet pieces at regular intervals are can be at the target of the multiple different size of a certain size scope endoadaptation.
Be further described below in conjunction with specific embodiment of the utility model shown in the accompanying drawing.
Fig. 1 is many with the structural representation that clamps spanner fast.
Fig. 2 is the vertical view after quick clamping spanner shown in Figure 1 removes protecting cover.
In Fig. 1～2,1-jaw wherein, 2-screw rod, 3-wrench body, 4-law spring, the 5-collar, 6-ratchet, 7-protecting cover, 8-wheel seat, 9-pulley, the 10-wheel shaft, 11-dials handle, 12-push button, 13-taper knob, the 14-steel wire rope, 15-spring, 16-steel ball, 17-ratchet, 18-connects ball, 19-clevis drawbar, 20-wheel shaft, 21-pulley, the 22-stator, 23-rivet, 24-screw, 25-hole.
With reference to Fig. 1～2, many its front ends that has a pipe type with quick clamping spanner of the present utility model are tubular, its main body has wrench body (3) metal shell of cavity, the bakelite handle (13) of size coupling with it is inserted in the rear end of wrench body (3), and middle upper portion shell face is drilled with hole (25), copper its hand push face triangular in shape promptly has the push button (12) of the class that can strengthen frictional resistance towards the one side of spanner rear end, screw (24) patchhole (25) by its bottom, mould and make pulley (21) is fixed on wrench body (3) by its metal wheel shaft (20) inner chamber rear portion, moulding system pulley (9) is fixed on by its wheel shaft (10) in the tubular of inner chamber front portion of wrench body (3) in the round empty cavity, multiply seizing wire (14) one ends are fixed on the screw (24), the other end is drawn to walk around by screw (24) and is passed stator (22) behind the pulley (21) and walk around and be fixed on screw rod (2) the intermediate bar wall after pulley (9) arrives screw rod (2), wherein go up one of serial connection and connect ball (18) by pulley (21) to pulley (9) this section steel wire rope (4), connect ball (18) junction, two ends by metal compounds hook (19) tying wire rope (14) and connection ball (18), regulate the length of steel wire rope (14) so that when fatigue deformation takes place steel wire rope (14), utilize clevis drawbar (19), the ratchet (6) that also has band metal collar (5) and wheel seat (8) on the above-mentioned screw rod (2), the top of wheel seat (8) has the protecting cover (7) on wrench body of being fixed on (3), be provided with metal law spring (4) between screw rod (2) and the ratchet (6) with favorable elasticity, one end of law spring (4) is fixed on the ratchet wheel body, the other end is fixed on screw shaft when being taken in the ineffective power of push button (12), law spring (4) can reset screw rod (2) by its elastic force, a side backwards of the preceding end ratchet (6) of wrench body (3) and its bridle joint is to be hinged on the ratchet (17) on the housing of wrench body (3) and to be dialled handle (11) by rivet (23) in addition, have the elastic force controlling organization of forming by spring (15) and steel ball (16) between curved surface one end of ratchet (17) and the lower house step of wrench body (3), and dial the direction of rotation that handle (11) can be used to conversion ratchet (6).Of the present utility model the using when the clamping spanner uses fast that constitutes thus more, as promoting push button (12) forward, steel wire rope (14) tension also drive screw rod (2) is rotated, and the left and right jaw of screw rod (2) screw thread transmission (1) moves to both sides respectively, so jaw is opened.Unclamp push button (12), clockwork spring (4) resets, make screw rod (2) turn round also screw thread transmission jaw (1) closure again, according to the target of different size, the width that can grasp the jaw unlatching adapts to target, after jaw (1) is clamped target, direction according to its required rotation, drive the work direction of rotation that ratchet (17) is determined ratchet (6) by dialling handle (11), as soon as determine that spanner can be started working.Respond well through sample examination operational verification, jaw clamps rapidly, the whole non-loosening phenomenon of anchor clamps and be fit to the target of the various models of all size in scope of design.
