Abstract
The utility model discloses a combined type spanner. The combined type spanner comprises a wrench body and a handle, wherein an upper wrench and a lower wrench are arranged on the wrench body, the upper wrench, the lower wrench and the wrench body form a notch, a sleeve is arranged in a position, close to the bottom of the notch, on the surface of the wrench body, and the sleeve is connected with the wrench body in a detachable mode. The combined type spanner enables the spanner and the sleeve to be combined and is convenient to use.
Description
Technical field
The utility model relates to a kind of hand-operated tools, especially relates to a kind of combined type spanner.
Background technology
In hand-operated tools, sleeve and open-end wrench are instrument independently, separately put usually, and as Chinese patent Granted publication number: CN 2223173, disclose a kind of plum blossom fork spanner, by handle, spanner, on pull body, pull body down and constitute.The last contact-making surface of pulling body in the spanner is the cambered surface of protruding downwards, and the following contact-making surface of pulling body down is cambered surface protruding upward.Opening in the spanner has interior contact-making surface and the interior contact-making surface down gone up near a side of handle.Last contact-making surface, interior contact-making surface down, all continuous by quincunx recess between the contact-making surface down.Interior upward contact-making surface and interior angle between the contact-making surface down are 120 degree.When part being installed or keeping in repair, run into through regular meeting and to use common open-end wrench comparatively be inconvenient to the occasion of work, the user need be switched sleeve and spanner back and forth at this moment, and it is comparatively inconvenient to use, and loses time, and has reduced production efficiency.
The utility model content
The utility model is in order to overcome existing spanner and sleeve is separately put, switch awkward deficiency back and forth, to provide a kind of spanner and sleeve are made up, use combined type spanner comparatively easily.
To achieve these goals, the utility model is by the following technical solutions:
A kind of combined type spanner of the present utility model, comprise spanner body and handle, the spanner body is provided with spanner and following spanner, and last spanner, following spanner and spanner body form a recess, described spanner surface is provided with sleeve near the notched bottoms place, and described sleeve and spanner body are for removably connecting.When part being installed or keeping in repair, can be directly by last spanner and following spanner grip bolt or nut, utilize handle to tighten or unscrew operation.When running into some specific positions, the occasion of using open-end wrench be inconvenient to work, as be positioned at the spiro keyhole position of surface of the work recessed position, the use open-end wrench can't be tightened when operating, and operates just switch to sleeve, thereby has improved production efficiency.In addition, sleeve can also be changed, and for bolt or the nut of different sizes, thereby it is adaptive with it to select corresponding sleeve to replace original sleeve, has therefore enlarged the scope of application of spanner.
As preferably, described sleeve comprises square shank and the body that is provided with trepanning, and described spanner body is provided with the locating hole suitable with shank.The shank of sleeve is inserted in the locating hole on the spanner body location that can finish sleeve.Shank is square, defines the rotary freedom of sleeve, makes sleeve to rotate synchronously with spanner.
As preferably, be provided with the magnet piece of the trepanning bottom surface of embedding in the described trepanning.When like this bolt or nut being put in the trepanning of sleeve, magnet piece is used for attracting bolt or nut, convenient with bolt or nut be transported to the position comparatively hidden, the comparatively zone of difficulty is installed, prevent that it from dropping.
As preferably, described shank is provided with aperture, is provided with ball in the described aperture, is provided with back-moving spring between described ball and the aperture.When abutment sleeve, when shank had just begun to be inserted in the locating hole, ball was subjected to the pressure of locating hole sidewall and moves mutually, the while compression reseting spring, when shank was inserted in the locating hole fully, the shank head passed from the another side of spanner body, and ball also just in time exposes at spanner external.This moment, ball ejected under action of reset spring, thereby sleeve is played position-limiting action, and sleeve is difficult for separating with the spanner body.
As preferably, describedly go up spanner, the edge of spanner, spanner body and handle is equipped with the flange perpendicular to plane, handle place down.Flange has improved the contact area of handle and staff, reduces the pressure that hand is subjected to, and uses more comfortable.In addition, the thickness of the main part of handle can suitably reduce, thereby reduces the use of material, has saved manufacturing cost.
As preferably, described handle is provided with hanging hole away from an end of spanner body.After conveniently finishing using, instrument hung deposit.
Therefore, the utlity model has following beneficial effect: (1) uses open-end wrench and sleeve combination comparatively convenient and swift; (2) sleeve can be changed, and applicability is higher.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is the structural representation of sleeve of the present utility model.
Among the figure, spanner body 1, sleeve 2, body 2a, trepanning 2b, shank 2c, aperture 2d, handle 3, flange 3a, hanging hole 4, following spanner 5, recess 6, last spanner 7, magnet piece 21, ball 22, back-moving spring 23.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Among the embodiment as shown in Figure 1, a kind of combined type spanner, comprise open-end wrench part and sleeve 2, open-end wrench part wherein is made up of spanner body 1 and handle 3 two parts, form a recess 6 by last spanner 7, following spanner 5 and spanner body, wherein go up the sidewall that spanner and following spanner are respectively recess, and the bottom surface of recess is on the spanner body.Sleeve is arranged on the spanner body, and the bottom of close recess, and sleeve is made of body 2a and shank 2c, is provided with trepanning 2b at body, thereby by locating hole square on the spanner body and the cooperation of the shank on the sleeve sleeve is installed on the spanner body.Also be provided with aperture 2d on shank, be provided with back-moving spring 23 in the aperture, the back-moving spring other end connects a ball 22.In addition, be provided with a magnet piece 21 in the trepanning of sleeve, this magnet piece is embedded in the trepanning bottom surface, is used for holding bolt or nut.Be provided with flange 3a at the edge of handle, flange is perpendicular to handle surfaces, improved the contact area with palm, improved the use feel.At the end of handle away from the spanner body, be provided with hanging hole 4, it is comparatively convenient that suspension is deposited.
Installing part or when maintenance, by last spanner, the recess that forms of spanner and spanner body down, grip bolt or nut shake handle afterwards and tighten or unscrew.When running into when using the occasion that open-end wrench is inconvenient to work, can utilize sleeve to operate.Sleeve can also be changed according to the size of bolt or nut, selects corresponding sleeve to replace original sleeve, can proceed operation.
