Abstract
The utility model relates to an externally joined rotation force redirector, which is characterized in that two bevel gears which are mutually engaged are arranged in a shell, wherein a driving bevel gear is connected with a transmission sleeve shaft or a transmission rotary shaft and a driven bevel gear is fixedly connected with a sleeve shaft which is connected with a clamping head. The rotating force in a horizontal direction can be converted into the rotating force in a vertical direction by the utility model, so that the assembly and the disassembly of screws and drilling in a narrow space can be carried out through the tools, such as a power screwdriver, or an air-operated screwdriver, a spanner, an electric drill, an air motor drill, etc. When the sleeve shaft of the utility model is not connected with the clamping head, the assembly and the disassembly of the screws can also be carried out in the narrow space.
Description
Technical field
The utility model is to belong to a kind of commentaries on classics power steerable tool, more particularly relates to the supporting commentaries on classics power commutators that are used for installing and removing screw and boring such as a kind of and electronic or pneumatic screw-driver, wrench, electric drill and air drill.
Background technique
In equipment installation and maintenance process, run into the situation of mounting or dismounting screw and boring through regular meeting, with traditional hand-operated tools, inefficiency not only, labor intensity is also big, can increase work efficiency greatly with instruments such as electronic or pneumatic screw-driver, wrench, electric drill and air drills, also become light, but when running into small spaces such as some sandwich walls, clamping plate, since be subjected to the restriction (about 35cm) of above-mentioned instrument self length can't vertical pendulum to normal operating position, screw and boring are installed and removed in this small space operation; And above-mentioned instrument lays flat on one's back and can stretch into this small space, but lay flat on one's back enter small space after because not right with the direction at the position that will operate, the staff still can't use above-mentioned instrument that small space is operated.
Though the angular electric drill that is specifically designed to the small space operation is arranged, the staff specially to buy the corner of table electric drill for this reason, they feel not to be very to one's profit.
Summary of the invention
The utility model is in order to solve above-mentioned technical barrier, provide a kind of externally connected type to change the power commutator, it can be converted into the rotating force of substantially horizontal the rotating force of Vertical direction, and instruments such as pneumatic or electronic screw-driver, wrench, electric drill and air drill can be to the mounting or dismounting screw and the boring of small space.
The technological scheme that the utility model solves is: externally connected type changes the power commutator, and it is that two mutually meshing bevel gears are housed in housing, wherein connects transmission sleeve or drive shaft, fixedly connected sleeve on the driven wheel of differential on the drive bevel gear.
Connect chuck on the above-mentioned sleeve.
Above-mentioned sleeve is provided with trepanning, and the inwall anchor ring of trepanning is non-circular.
Above-mentioned transmission sleeve is provided with trepanning, and the inwall anchor ring of trepanning is non-circular.
The outer diametric plane of the outer end portion of above-mentioned drive shaft is non-circular.
Above-mentioned housing is provided with safety enclosure.
Be connected with connection handle on the above-mentioned housing.
Be connected with handle on the above-mentioned housing.
Above-mentioned housing is provided with screw, and connection handle and handle are screwed onto in this screw, is bolted with on this screw and tightens up screw.
It can be converted into the rotating force of substantially horizontal the rotating force of Vertical direction, so that instruments such as electronic or pneumatic screw-driver, wrench, electric drill and air drill can be to the mounting or dismounting screw and the boring of small space.When not connecting on the utility model sleeve under the situation of chuck, also can install and remove screw to small space.
Description of drawings
Connect drive sleeve axle construction schematic representation on the drive bevel gear of Fig. 1 for the commutator of externally connected type commentaries on classics power;
Connect the drive shaft structural representation on the drive bevel gear of Fig. 2 for the commutator of externally connected type commentaries on classics power;
Fig. 3 changes the structural representation that the power commutator does not have chuck for externally connected type;
Embodiment
Embodiment 1, externally connected type as shown in Figure 1 changes the power commutator, two bevel gears that are meshed 2 are housed in housing 1,3, wherein connect transmission sleeve 5 on the drive bevel gear 2, transmission sleeve 5 outer end portion are provided with trepanning 51, trepanning 51 inwall anchor rings are quadrilateral, and be provided with card pearl groove, be connected with sleeve 4 on the driven wheel of differential 3, sleeve 4 inside are provided with trepanning 41, these trepanning 41 inwall anchor rings are Hexagon, and elastic collar is housed, and the bottom of trepanning 41 is provided with chuck screw screw, and the outer diametric plane of the fore-end of sleeve 4 is quadrilateral, and the card pearl is housed, the fore-end of trepanning 41 is equipped with card pearl shell fragment, makes the card pearl of packing into have elasticity, is convenient to connect chuck 6 or turnbuckle, chuck 6 is provided with corresponding quadrilateral trepanning and card pearl groove, chuck 6 is inserted on the front end 42 of sleeve, and chuck screw 61 screws in chuck 6 the chuck screw screw, makes the fixedly connected chuck 6 of sleeve.Sleeve 4 also is equipped with bearing 53, transmission sleeve 5, sleeve 4 and two bevel gears that are meshed 2,3 can be in housing 1 smooth rotation.Be bolted with connection handle 7 and handle 13 on the housing 1, the other end sleeve of connection handle 7 is in draw-in groove 8, and draw-in groove 8 is fixed on the casing 9 of electric drill, and housing 1 is provided with screw 10, connection handle 7 and handle 13 are screwed onto in the screw 10, and are bolted with in the opposite direction of screw 10 and tighten up screw 11.Housing 1 also is provided with safety enclosure 12, and the outer diametric plane of electric drill main shaft 91 can be quadrilateral.
Working principle: during use transmission sleeve 5 is enclosed within on the main shaft of electric drill, externally connected type changes the power commutator can utilize the chuck of pulling down on the electric drill, open electric drill, the electric drill rotating force is delivered on the drive bevel gear 2 by the transmission sleeve, and transmit in opposite directions through master bevel gear 2 rotating force with driven wheel of differential 3, the power of horizontally rotating is converted into vertical rotating force, again by the sleeve 4 output rotating forces that are connected on the driven wheel of differential 3, batch chewing 100 is enclosed within the trepanning 41, just can install and remove screw, screw to small space; Connect chuck 6 on the sleeve 4, just can be by chuck 6 output rotating forces, to criticize and chew 100 and be clamped in the chuck 6, the work of being convenient to can be installed and removed screw, screw or boring to small space.
