Abstract
The invention discloses a wheel wrench which comprises a wrench head and a handle, wherein the wrench head is arranged at one end of the handle, the handle is hollow, a limit stop collar which is sheathed on the handle is further arranged at the other end of the handle, and a small hole is formed on the limit stop collar; the wheel wrench further comprises an extension stem, the extension stem penetrates the small hole on the limit stop collar and is arranged in the handle; and the caliber of one end of the extension stem arranged in the handle is bigger than that of the small hole on the limit stop collar. The wheel wrench has the advantages that the extension stem which can move is arranged in the handle, thereby facilitating the use of the wrench; when the extension stem is extended, the torque is increased, and the force used on the wrench is reduced, thereby playing the role of saving effort; when not in use, the extension stem is contracted in the handle, thereby facilitating the collection; and the extension stem can be extended or contracted to the ideal length from the maximum to the minimum telescopic range in a narrow space, thereby facilitating the use and realizing the work demands of special occasions.
Description
Technical field
The present invention relates to a kind of automobile-used hardware ﹠ tools, particularly a kind of wheel wrench.
Background technology
In hardware ﹠ tools, spanner is common a kind of instrument, and spanner generally is made up of the handle of spanner and spanner lower end.By physical knowledge as can be known, handle is long more, and the strength that is used in the spanner topmounter will be more little, but as the spanner of instrument owing to preserving reasons, particularly automotive wrench such as convenience, space, the handle of spanner is impossible oversize; Sometimes, the handle of spanner is long, also is unfavorable for the use of spanner at small space.
Summary of the invention
Technical problem to be solved by this invention provides a kind of simple in structure, can regulate the wheel wrench of pinch bar length easily and flexibly.
In order to solve the problems of the technologies described above, technical scheme of the present invention is: a kind of wheel wrench comprises spanner and handle, spanner is arranged on an end of handle, described handle is a hollow, also is provided with the stop collar that is enclosed within on the handle at the other end of handle, and stop collar is provided with aperture; Described wheel wrench also comprises extension stem, and the aperture that extension stem passes on the stop collar is arranged on handle inside; Be arranged on an end of the extension stem in the handle, the bore of aperture is big on its relative aperture stop collar.
For the ease of using, described handle and extension stem are tubulose.
In order to limit the length that interior pipe gos deep into handle, the inwall of described handle is provided with spacing point.
In order to utilize the limit function of stop collar better, the material of described stop collar is a nylon material.
For the maximization of the function of use of wheel wrench, be provided with the sled handle at the other end of described extension stem, so just can be used as spanner when using, also can be used as other purposes.
Advantage of the present invention is: the present invention be provided with in the inside of handle can be movable extension stem, made things convenient for the use of spanner, during the extension stem elongation, increased moment, make the strength that is used on the spanner diminish, play the labour-saving effect; Not the time spent, extension stem is contracted in the handle, convenient collection; In narrow space, extension stem also can be flexible to desirable length in maximum, minimum flexible scope, and convenient the use realized the work requirements of special occasions.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
The present invention will be further described in detail below in conjunction with specific embodiment.
As shown in drawings, a kind of wheel wrench comprises spanner 1 and handle 2, spanner 1 is arranged on an end of handle 2, and described handle 2 is a hollow, also is provided with stop collar 3 at the other end of handle 2, and stop collar 3 is provided with aperture 4; In order to increase the effective torque of spanner, be provided with extension stem 5 in the inside of handle 2, for the ease of using, handle 2 and extension stem 5 use tubular material.The aperture 4 that extension stem 5 passes on the stop collar 3 is arranged on handle 2 inside, aperture 4 bores on the bore of extension stem 5 and the stop collar 3 are suitable, frictional force limit between extension stem 5 and the stop collar 3 has increased like this, the use of favourable handle 2, extension stem 5 is unlikely in handle 2 slides within, and an end of extension stem 5 is arranged in the handle 2, and the bore of aperture is big on its relative aperture stop collar, like this, extension stem 5 just can not detach handle 2.
In order to limit the length that extension stem 5 gos deep into handle 2, the inwall of described handle 2 is provided with spacing point 7.Stop collar 3 of the present invention can use material manufacturings such as plastics, nylon, and in order to utilize the limit function of stop collar 3 better, the material of stop collar 3 is a nylon material.
The other end of extension stem 5 also can also be provided with the instrument of other types, for example prizes handle 8, when so just can be used as the spanner use, also can be used as 1 other purposes.
During use, the strength of Shi Yonging is too big if desired, just extension stem 5 can be extracted out in handle 2, stretches to suitable length, just can rotate spanner like a cork, thereby play the effect of saving strength.
When not using,, saved the space with extension stem 5 indentation handles 2.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
