(3) beneficial effect
Technique scheme of the present utility model has following advantage: by described handgrip chuck being arranged on described annulus inside and matching with described annulus, described torque adjusting assembly is arranged in the inner chamber of described cylindrical shape handle and with described handgrip chuck by the straight pin clamping, when the spanner screw-down torque surpasses the maximum moment value that screw tap can bear, skid between handgrip chuck and the straight pin, even be rotated further handle again, the handgrip chuck also no longer rotates, thereby prevents that the excessive phenomenon of screw tap fracture that causes of moment from taking place.
Description of drawings
Fig. 1 is the profile of the utility model embodiment tapping spanner;
Fig. 2 is the assembling schematic diagram of the utility model embodiment tapping spanner and wire taper sleeve.
Among the figure, 1: the handgrip chuck; 2: straight pin; 3: piston; 4: spring; 5: screw; 6: expansion link; 7: the cylindrical shape handle; 8: second handle; 9: annulus; 10: wire taper sleeve.
The specific embodiment
Below in conjunction with drawings and Examples the specific embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As depicted in figs. 1 and 2, the tap wrench that the utility model provides comprises cylindrical shape handle 7, annulus 9, has handgrip chuck 1 and the torque adjusting assembly of arc notch, one end and the described annulus 9 of described cylindrical shape handle 7 are connected as a single entity, the center of described handgrip chuck 1 has a square hole, it is inner and match with described annulus 9 that described handgrip chuck 1 is arranged on described annulus 9, described torque adjusting assembly be arranged in the inner chamber of described cylindrical shape handle 7 and with described handgrip chuck 1 by straight pin 2 clampings.The square hole of described handgrip chuck 1 is used for and the wire taper sleeve 10 of different model matches, and preferably, described handgrip chuck 1 can be magnetic handgrip chuck, and the arc notch of handgrip chuck 1 and torque adjusting assembly matches with straight pin 2 respectively.
Described torque adjusting assembly comprises piston 3, spring 4 and screw 5, one end of described piston 3 is connected by spring 4 with described screw 5, the other end of described piston 3 has arc notch, by straight pin 2 clampings, described screw 5 is connected with the inner thread of described cylindrical shape handle 7 inner chambers between the arc notch of the arc notch of described piston 3 and described handgrip chuck 1.
The screw-down torque difference that different screw taps can bear, the screw-in by screw 5 or screw out can regulating spring 4 stroke, thereby can stipulate out the maximum moment value that different screw taps can bear.
During use, slewing circle tubular handle 7, because the torque adjusting assembly in cylindrical shape handle 7 inner chambers and handgrip chuck 1 are by straight pin 2 clampings, limited the relative slip of cylindrical shape handle 7 and handgrip chuck 1, thereby cylindrical shape handle 7 drives handgrip chuck 1 and rotates, and then handgrip chuck 1 drives screw tap rotation realization tapping by wire taper sleeve 10, in tapping process, when screw-down torque reaches the maximum moment value that screw tap can bear, handgrip chuck 1 extruding straight pin 2, straight pin 2 extruding moment adjusting parts, because the torque adjusting assembly has elasticity, skids between handgrip chuck 1 and the straight pin 2, even be rotated further handle again, chuck also no longer rotates, thereby has avoided the excessive fracture that causes screw tap of screw-down torque.
Preferably, uniform six arc notch on the edge of described handgrip chuck 1.Like this, after skidding between handgrip chuck 1 and the straight pin 2, straight pin 2 can match with next breach easily very soon, in time changes screw tap and adjustment screw 5 then.
Further, insert wire taper sleeve 10 in the square hole of described handgrip chuck 1, described wire taper sleeve 10 can be selected different models for use, thereby makes described spanner can cooperate different screw taps to use.
As depicted in figs. 1 and 2, described tap wrench also comprises second handle 8, described second handle 8 is arranged on the described annulus 9 symmetrically with described cylindrical shape handle 7, be arranged with expansion link 6 at described second handle 8, like this, can regulate the length of the arm of force, to reduce exerting oneself in the hand tapping process.Equally, also can be on cylindrical shape handle 7 sheathed expansion link 6, when using spanner, the size that can regulate the arm of force by expansion link.
In sum, the adjustable tap wrench of the moment that the utility model provides is by being arranged on described handgrip chuck 1 described annulus 9 inside and matching with described annulus 9, described torque adjusting assembly is arranged in the inner chamber of described cylindrical shape handle 7 and with described handgrip chuck 1 by straight pin 2 clampings, when the spanner screw-down torque surpasses the maximum moment value that screw tap can bear, skid between handgrip chuck 1 and the straight pin 2, even be rotated further handle again, handgrip chuck 1 also no longer rotates, thereby has prevented that the excessive phenomenon of screw tap fracture that causes of moment from taking place; Square hole by handgrip chuck 1 matches with the wire taper sleeve 10 of different model, makes described spanner can cooperate different screw taps to use; By sheathed expansion link 6 on second handle 8 or cylindrical shape handle 7, regulate the length of the arm of force, reduced exerting oneself in the hand tapping process.
The above only is a kind of preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
