Description
Technical field
The utility model relates to a kind of hand power tool, the labour-saving spanner of using especially for the nut dismounting of motor tire.
Background technology
Continuous development and progress along with modern society, automobile has become an indispensable part in people's daily life, therefore the maintenance of automobile also just becomes more general, and the nut that mode that big spanner or big spanner and its shank put a long lever unscrewed or tightened motor tire is continued to use in the dismounting that is used for motor tire always.Operator's effort is bigger during with the nut of above-mentioned way dismounting motor tire, occurs often that corrosion is twisted not open or the phenomenon of fastening force inequality, deficiency, repaiies the inconvenience of changing thereby cause, and What is more also may cause in the running car vibration of the fastener phenomenon that gets loose.At present, the most complex structure of the special wrench that exists on the market, make difficulty, manufacturing cost is high.
Summary of the invention
At the above-mentioned defective that existing dismounting automotive tyre nut instrument exists, the utility model aims to provide a kind of labour-saving spanner of automotive wheels special use.
The utility model realizes that the technical scheme that the foregoing invention purpose is adopted is: a kind of automobile labour-saving spanner, comprise: hand crank, the saddle carriage, disc holder, it is characterized in that: be fixed with main gear axle sleeve and middle biography gear bush on the described saddle carriage, be with main gear shaft in the described main gear axle sleeve, pass an end that passes gear wheel shaft in being with in the gear bush in described, pass on the gear wheel shaft in described and be connected with and main gear shaft ingear presbyopia gear, the number of teeth of described main gear shaft is less than the number of teeth of described presbyopia gear, be fixed with the middle biography gear bush that passes the gear wheel shaft other end in being with on the described disc holder, described disc holder is embedded with the square hole joint, this square hole joint top with captive joint with middle biography gear wheel shaft ingear light eye gear, pass the number of teeth of the number of teeth of gear wheel shaft in described less than described light eye gear, described square hole joint is with the square hole joint overcoat of captiveing joint with disc holder outward, described square hole joint bottom cover is inserted an end of square toes transmission shaft, this square toes transmission shaft is with the transmission shaft sheath of captiveing joint with square hole joint overcoat outward, the other end of described square toes transmission shaft be plugged on nut pullover in, described cow tongue dop is captiveed joint with the transmission shaft sheath.
During equaling, the described main gear shaft number of teeth passes the gear wheel shaft number of teeth.
The described presbyopia gear number of teeth equals the light eye gear number of teeth.
Described square hole joint overcoat is provided with butter and chews.
The utility model has been compared following beneficial effect with prior art: 1. adopt the secondary gear transmission, make more labour-saving dismounting motor tire of operator; 2. compact conformation, volume is little, is easy to carry; 3. simple in structure, handling ease, cheap for manufacturing cost;
Description of drawings
Fig. 1 is the integral installation figure of a kind of automobile of the utility model with labour-saving spanner,
The specific embodiment
Be provided with a perforate in the middle of the saddle carriage 3, main gear axle sleeve 4 is fixed in the described perforate, pass the hole of gear bush 7 during left-right symmetric has and is used for fixing on the described saddle carriage 3, be with main gear shaft 1 in the described main gear axle sleeve 4, the number of teeth of main gear shaft 1 is preferably 4 teeth, pass an end that passes gear wheel shaft 2 in being with respectively in the gear bush 7 about described in two, pass the gear wheel shaft number of teeth in described and be preferably 4 teeth, pass difference captive joint and main gear shaft 1 ingear presbyopia gear 6 on the gear wheel shaft 2 in described two, the number of teeth of this presbyopia gear 6 is preferably 25 teeth.Have three perforates on the disc holder 9, wherein, middle perforate is embedded with square hole joint 10, about pass the middle biography gear bush 7 of gear wheel shaft 2 other ends in being fixed with respectively in two perforates, described square hole joint 10 top captive joints and middle biography gear wheel shaft 2 ingear light eye gears 8, the number of teeth of this light eye gear 8 is preferably 25 teeth, described square hole joint 10 outer being with disc holder solid 9 are decided bonded assembly square hole joint overcoat 11, this square hole joint overcoat 11 has the butter that is used to fill the lubricating oil that reduces cliding friction and chews 12, the fluting of described square hole joint 10 bottoms is cubic type, cover is inserted an end of square toes transmission shaft 13 in it, these square toes transmission shaft 13 outer transmission shaft sheaths 14 of captiveing joint that are with square hole joint overcoat 11, the other end of described square toes transmission shaft 13 is plugged in the cubic type fluting on pullover 16 tops of nut, and described transmission shaft sheath 14 is captiveed joint with cow tongue dop 15.
During nut on the motor tire of fastening or dismounting, only need nut pullover 16 is enclosed within on the nut of wanting fastening or dismounting, cw or conter clockwise shake hand crank 5 again, hand crank 5 rotates and drives main gear shaft 1 rotation, main gear shaft 1 and 6 engagements of presbyopia gear, presbyopia gear 6 and middle biography gear wheel shaft 2 coaxial rotation, the middle gear wheel shaft 2 that passes meshes with light eye gear 8, thereby light eye gear 8 rotates the square toes transmission shafts 13 that drive in the square hole joint 10 rotation drive square hole joints 10 and rotates, square toes transmission shaft 13 rotates and drives nut sleeve 16 rotation, thereby drive the nut in the nut pullover 16, cow tongue dop 15 blocks a bearing, so disc holder 9, square hole joint overcoat 11, transmission shaft sheath 14 and cow tongue dop 15 are with respect to transmission shaft 13 transfixions, behind above-mentioned double underdrive, realize the transmission of moment of torsion, thereby reach the purpose of the nut on more effectively fastening or loosening motor tire under the situation that reduces the operating personal working strength.
Adopt the main gear shaft number of teeth to pass the gear wheel shaft number of teeth in equaling, the presbyopia gear number of teeth equals the light eye gear number of teeth simplified processing process of being more convenient for, and is suitable for large-scale production.
