Abstract
A turnable spanner comprises a mounting shaft and a spanner handle, wherein the mounting shaft is connected with the spanner handle through a ball journal, the ball journal is installed in the middle of a turning disc, the turning disc is fixedly connected with the mounting shaft, the spanner handle is movably connected with the ball journal and can rotate around any direction of the ball journal, the periphery of the turning disc is uniformly provided with more than three fixing grooves, the width of the fixing grooves is greater than the width of the spanner handle, the depth of the fixing grooves is not smaller than two thirds of the spanner handle, and the bottom end of the mounting shaft is provided with a built-in mounting hole. In the use process of the turnable spanner, the spanner handle can be turned without being taken down, the mounting efficiency is improved, the operation process is simplified, and the use is more labor-saving.
Description
Technical field
The utility model relates to reversible spanner, and it is in use a kind of, and the spanner that the direction of spanner handle can conversion, belong to the spanner field.
Background technology
Spanner is the instrument of tightening or unscrew screw, nut etc.the spanner handle of conventional spanner and Wrench head are the integral body that is fixed as one, the position of spanner handle and Wrench head is fixed, little spanner in use, comparatively laborsaving, the people can 360 ° of rotary spanner handles, in the object that the securing member precession is connected, when spanner is very large, the securing member that need to screw is difficult to enter while being connected in object, need firmly larger, the people is difficult to realize 360 ° of rotations not intermittently, the common way of people is, spanner is rotated to the scope of the own most convenient application of force, then spanner is taken off, spanner handle is changed to the initiating terminal of application of force scope, again spanner is installed to securing member, rotate to the end of application of force scope, again spanner is taken off, change the initiating terminal of direction to application of force scope, circulation successively.When such spanner uses, constantly change direction, repeatedly assembly wrench and securing member, troublesome poeration, efficiency is low, relatively effort.
Summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses reversible spanner, the handle position of this spanner can conversion, when turn Fastener, do not need whole spanner is taken off from securing member, the installation or removal securing member is more laborsaving, operate simplyr, installation effectiveness is high.
Reversible spanner, comprise installation shaft and spanner handle, and described installation shaft is connected by ball journal with spanner handle, ball journal is arranged on the centre of break-in dish, break-in dish and installation shaft fixed-link, spanner handle and ball journal are for being flexibly connected, and spanner handle can rotate around the ball journal any direction.
The surrounding of described break-in dish evenly is provided with the holddown groove more than 3, and the width of holddown groove is greater than the width of spanner handle, and the degree of depth of holddown groove is not less than 2/3 of spanner handle.
The bottom of described installation shaft is provided with built-in installing hole.
Described installation shaft, break-in dish and ball journal position maintain static.
The utility model, simple in structure, easy to use laborsaving, during use, securing member is placed in the connecting hole of fastened object to the head clamping of the installing hole of spanner and securing member, spanner handle is placed in holddown groove, and rotary spanner handle, securing member are followed spanner handle and rotated together, after the rotation certain limit, the people will badly firmly lift spanner handle around ball journal, put in next convenient holddown groove firmly, the recycling replacing holddown groove, until in securing member precession connecting hole.
The accompanying drawing explanation
Fig. 1 is longitudinal sectional view of the present utility model,
Fig. 2 be the A of Fig. 1 to view,
Reference numerals list: 1-spanner handle, 2-break-in dish, 3-holddown groove, 4-ball journal, 5-installation shaft, 6-installing hole.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand the following specific embodiment and only be used to the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometric center.
Fig. 1 is structural representation of the present utility model, as we can see from the figure, this reversible spanner, comprise installation shaft 5 and spanner handle 1, described installation shaft 5 is connected by ball journal 4 with spanner handle 1, and ball journal 4 is arranged on the centre of break-in dish 2, break-in dish 2 and installation shaft 5 fixed-link, spanner handle 1 is with ball journal 4 for being flexibly connected, and spanner handle 1 can be around ball journal 4 any direction rotations.The utility model, installation shaft 5 are used for the head clamping with securing member, and spanner handle 1 use messenger is holding firmly rotation, drives installation shaft 5 rotations, and then, in the object that securing member precession fastener is connected.Spanner handle 1 can realize that spanner handle 1 changes to another holddown groove 3 from a holddown groove 3 around ball journal 4 to any rotation, and break-in dish 2 is used for changing direction to spanner handle 1.
The surrounding of described break-in dish 2 evenly is provided with the holddown groove 3 more than 3, and the width of holddown groove 3 is greater than the width of spanner handle 1, and the degree of depth of holddown groove 3 is not less than 2/3 of spanner handle 1.Holddown groove 3 more than 3 can be changed suitable direction of exerting oneself in order to meet spanner handle 1, and the width of holddown groove 3 is in order to meet the complete depression of spanner handle 1 energy in holddown groove 3.
The bottom of described installation shaft 5 is provided with built-in installing hole 6.Installing hole 6 use are opened the head of securing member are connected to wherein.
Described installation shaft 5, break-in dish 2 and ball journal 4 positions maintain static, and fixing position, rotate installation shaft 5 together with break-in dish 2, realize the effect of turn Fastener.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme that is comprised of above technical characterictic any combination.
