The main body is provided with a pair of outer side plates, and the two ends of the main body are provided with a working head and a handle; the outer side plate is provided with a through hole at one end of the working head respectively; a driving wheel which can rotate and is axially arranged in the working head is arranged in the working head; the driving wheel is hollow cylindrical, the inner ring surface is annular tooth-shaped, the peripheral surface is distributed with driving teeth, and the driving wheel is installed in the outer side plate through hole and is axially limited in the working head. The utility model provides a spanner is used to little space, simple structure, low in manufacturing cost, it is convenient to use, has effectively solved bolt dismouting time-consuming, hard problem in narrow and small space, has improved work efficiency and security.
Description
Technical Field
The utility model relates to a spanner, in particular to spanner that can use in narrow and small space.
Background
At present, because mechanical equipment structure is compacter and compacter, and the size is littleer and smaller, and its bolt installation space is all narrower, especially has other parts in the periphery to block under the condition, and the gyration space is narrow and small, and traditional spanner all needs very big gyration space when using, so traditional spanner often hardly uses for the bolt dismouting is inconvenient, efficiency reduces.
Disclosure of Invention
In order to solve the problem, the utility model provides a spanner is used to little space can effectively solve bolt dismouting time-consuming, hard problem in narrow and small space, improves work efficiency and security.
Solve the utility model discloses the technical scheme that the problem was taken is: a small-space application wrench comprises a main body, a working head, a transmission gear set and a handle.
The main body is provided with a pair of outer side plates, and the two ends of the main body are provided with a working head and a handle.
The outer side plates are respectively provided with a through hole at one end of the working head.
The working head is internally provided with a driving wheel which can rotate and is axially arranged inside the working head.
The driving wheel is hollow cylindrical, the inner ring surface is annular tooth-shaped, the peripheral surface is distributed with driving teeth, and the driving wheel is installed in the outer side plate through hole and is axially limited in the working head.
The transmission gear set is arranged between the outer side plates of the main body in a shaft mode, the transmission gear sets are meshed in sequence, the first gear is provided with a handle, and the last gear is meshed with the driving wheel.
The handle is arranged at the head gear, and the rotating handle can drive the transmission gear set to rotate.
The utility model provides a spanner is used to little space, simple structure, low in manufacturing cost, it is convenient to use, has effectively solved bolt dismouting time-consuming, hard problem in narrow and small space, has improved work efficiency and security.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a small space application wrench comprises a main body 1, a working head 2, a transmission gear set 3 and a handle 4.
The main body 1 is provided with a pair of outer side plates 5, and the two ends of the main body 1 are provided with a working head 2 and a handle 4.
The outer plates 5 each have a through-hole 51 at one end of the working head 2.
The working head 2 is internally provided with a driving wheel 6 which can rotate and is axially arranged inside the working head 2.
The driving wheel 6 is hollow and cylindrical, the inner annular surface of the driving wheel is annular tooth-shaped, driving teeth are distributed on the outer peripheral surface of the driving wheel, and the driving wheel is installed in the outer side plate through hole 51 and is limited in the working head 2 along the axial direction.
The transmission gear set 3 is axially arranged between the outer side plates 5 of the main body 1, the transmission gear set 3 is sequentially meshed, the head gear 31 is provided with a handle, and the tail gear 32 is meshed with the driving wheel 6.
The handle 7 is arranged at the head gear 31, and the rotating handle 7 can drive the transmission gear set 3 to rotate.
In the narrow and small position in space, the utility model discloses during the use, locate the nut with 6 covers of drive wheel, turning handle 7 again, handle 7 drives first gear 31 and rotates, and then drive transmission gear group 3 rotates, and simultaneously, last gear 32 also can promote drive wheel 6, makes 6 drive nut rotations of drive wheel to reach the purpose of installing and removing the bolt.
The utility model provides a spanner is used to little space, simple structure, low in manufacturing cost, it is convenient to use, has effectively solved bolt dismouting time-consuming, hard problem in narrow and small space, has improved work efficiency and security.
