Abstract
The utility model discloses a ratchet wrench. A force application point gear is arranged at one end of the ratchet wrench. A double-layer gear is arranged at the other end of the ratchet wrench. A belt which can transmit external force applied by the force application point gear to the double-layer gear is connected between the force application point gear and the double-layer gear. The double-layer gear is used for fixing and rotating a nut or a bolt. According to the ratchet wrench, a motion force application point can be moved to a place with wide motion space through the transmission functions of the belt and the gears, and the problem that a bolt or a nut in special narrow space can not be rotated is solved.
Description
Technical field
The relevant a kind of ratchet spanner of the utility model, refer to especially a kind of can be in narrow space the ratchet spanner of swivel bolt or nut.
Background technology
Ratchet spanner is instrument commonly used in a kind of daily life, is usually used in swivel bolt or nut.But, under some extreme condition, as in narrow space zone rotation nut or bolt process, because narrow space causes rotary speed slowly even can't rotate, therefore be necessary ratchet spanner is improved.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of ratchet spanner that can make things convenient for swivel bolt or nut in narrow space.
For achieving the above object, the utility model provides a kind of ratchet spanner, the one end is provided with point of application gear, the other end is provided with double-layer gear, be connected with the belt that point of application gear externally applied forces can be transferred to double-layer gear between this point of application gear and the double-layer gear, this double-layer gear is fixed and is rotated nut or bolt.
Described double-layer gear includes first gear of outer ring and second gear of inner ring, the diameter of this first gear is greater than the diameter of second gear, by bearing pin interlock, this second gear links to each other with described point of application gear by described belt between this first gear and second gear.
Described point of application gear centre is fixedly connected with the hexagonal gear shaft.
Described first gear is the gear of the ratchet mechanism form of control direction of rotation.
Described bearing pin one end is provided with flexibly indentation and exposes the steel ball of bearing pin, and this bearing pin is by the external extension bar of this steel ball stopper one, bolt or the nut of this extension bar stopper corresponding size.
The utility model is transferred to the place of space greatly by the transmission agency of belt and gear with the point of application that moves, and has solved the bolt of special narrow space or the problem that nut can't rotate.
Description of drawings
Fig. 1 is the Facad structure schematic diagram of the utility model ratchet spanner;
Fig. 2 is the side structure schematic diagram of the utility model ratchet spanner.
The specific embodiment
For ease of structure of the present utility model and the effect that reaches are had further understanding, the existing preferred embodiment that develops simultaneously by reference to the accompanying drawings is described in detail as follows.
As Fig. 1 and shown in Figure 2, ratchet spanner one end of the present utility model is provided with point of application gear 1, the other end is provided with double-layer gear 2, be connected with the belt 3 that point of application gear 1 externally applied forces can be transferred to double-layer gear 2 between this point of application gear 1 and the double-layer gear 2, this double-layer gear 2 is in order to fixing and rotation nut or bolt.
Double-layer gear 2 includes first gear 20 of outer ring and second gear 21 of inner ring in the utility model, the diameter of this first gear 20 is greater than the diameter of second gear 21, link by a bearing pin 22 between this first gear 20 and second gear 21, this first gear 20 is constructed to realize the exposed gear of ratchet mechanism, and second gear 21 links to each other with point of application gear 1 by belt 3.Point of application gear 1 center fixation is connected with hexagonal gear shaft 10, and hexagonal gear shaft 10 is constructed to use the size of common wrench action.In actual use, when if nut or bolt are positioned at narrow space inside, use common ratchet spanner directly to screw, then ratchet spanner double-layer gear 2 one ends of the present utility model are goed deep into narrow space internal fixation nut or bolt, point of application gear 1 one ends are positioned at space outerpace, rotate hexagonal gear shaft 10 by common wrench, apply external force and drive 1 rotation of point of application gear at hexagonal gear shaft 10, transmission by belt 3 drives 21 rotations of second gear, drive belt 3 and then make double-layer gear 2 move in the lump thereby reach point of application gear 1, thereby reach the transmission of power.Bearing pin 22 1 ends in the utility model also are provided with flexibly indentation and expose the steel ball 23 of bearing pin 22, this bearing pin 22 can be by the external extension bar (not shown) of steel ball 23 stoppers one, extension bar is of different sizes specification, but bolt or the nut of extension bar stopper corresponding size, when nut or bolt are positioned at narrow space and are not easy to directly pass through first gear, 20 stoppers, can be on bearing pin 22 an external extension bar, by extension bar stopper bolt or the nut of corresponding size specification, reach the purpose of swivel bolt or nut by the transmission of above-mentioned external force.First gear 20 is a ratchet mechanism, can control torsional direction by external knob, realizes up time or inverse time spinfunction.
The above is preferred embodiment of the present utility model only, is not for limiting protection domain of the present utility model.
