The various exemplary embodiments of the utility model are described in detail now with reference to attached drawing.It should also be noted that unless another It illustrates outside, the component and the positioned opposite of step, numerical expression and numerical value otherwise illustrated in these embodiments is unlimited The scope of the utility model processed.

Be to the description only actually of at least one exemplary embodiment below it is illustrative, never as to this is practical Novel and its application or any restrictions used.

Technology and equipment known to person of ordinary skill in the relevant may be not discussed in detail, but in appropriate situation Under, the technology and equipment should be considered as part of specification.

It is shown here and discuss all examples in, any occurrence should be construed as merely illustratively, without It is as limitation.Therefore, other examples of exemplary embodiment can have different values.

It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi It is defined in a attached drawing, then in subsequent attached drawing does not need that it is further discussed.

The utility model provides a kind of fixed device, as shown in Figs 1-4, including substrate 1, supporting element 3 and fastener 4. The surface of substrate 1 is formed down the cavity 2 with opening, and at least one end of cavity 2 and the side wall of substrate 1 penetrate through.Cavity 2 Openings of sizes is corresponding with fixture 5 with shape, and fixture 5 is inserted into cavity from one end that the side wall of cavity 2 and substrate 1 penetrates through In 2, and it is connected to opening, fixture 5 is enable to stretch out the position processed from opening.Supporting element 3 be set to by Between fixing piece 5 and the bottom of cavity 2, the bottom of cavity 2 is provided with through-hole, and fastener 4 passes through through-hole and abuts with supporting element 3, Fixture 5 can be made to be fastened between the opening of cavity 2 and supporting element 3, so as to the opening to fixture 5 from cavity 2 The part of stretching is processed.

Fixed device provided by the present application, fixture 5 utilize 3 He of supporting element from the side wall of substrate 1 insertion cavity 2 Fixture 5 is fixedly secured on substrate 1 by fastener 4, and after processing is completed to fixture 5, loosening fasteners 4 can incite somebody to action Fixture 5 takes out.Fixture structure is simple, easy to operate, and the installation and removal of fixture 5 are all fast.Example Such as, when fixture 5 is flat thimble, flat thimble can be fixedly secured on substrate 1, flat thimble is avoided to add There is the phenomenon that flying needle during work, improves the safety with higher in process of flat thimble, meanwhile, fixed dress Sizes, a plurality of types of flat thimbles can be processed by setting, and improve the versatility of fixed device.

Specifically, supporting element 3 includes the support column 31 abutted with fixture 5 and the supporting block abutted with support column 31 32, fastener 4 is abutted with supporting block 32.By fastener 4 to the extruding force of supporting block 32, fixture 5 can be made to be stabilized in Between support column 31 and the opening of cavity 2, to be processed to fixture 5 from the part that opening is stretched out.Support column 31 Setting can be such that supporting element 3 is formed with multiple positions of fixture 5 and contact, improve the fastening effect to fixture 5, The case where making it be less prone to shaking when processed.

Further, the one side that supporting block 32 is abutted with support column 31 is arc groove face.The setting in arc groove face, makes Be not likely to produce and move left and right between support column 31 and the bearing surface of supporting block 32, so support column 31 more steadily with supporting block Cooperate between 32, further increases the fastening effect to fixture 5 of fixed device.Those skilled in the art can root Other shapes can be set by the bearing surface of supporting block 32 and support column 31 according to needs, for example, supporting block 32 and support column 31 Bearing surface is section groove surface triangular in shape, and support column 31 is located in groove surface.Those skilled in the art can also be according to need It wants, the other selections of concrete composition component progress and design to supporting element 3, all schemes that can reach similar technology effect, all Belong to the protection scope of the application.

Specifically, screw thread is provided in through-hole, fastener 4 is jackscrew, and jackscrew is rotatably arranged in through-hole.Pass through rotation Turn jackscrew, its length for protruding into cavity 2 can be changed, so as to change the abutting force between jackscrew and supporting element 3, realization pair The fastening and disassembly of fixture 5.When fixed device need to fix the fixture of different sizes or type, by changing jackscrew The length for screwing in cavity 2, can be realized the fastening to various sizes of fixture.

Optionally, the bottom setting of cavity 2 is there are two through-hole, there are two fastener 4 is also provided with, is located at two through-holes In.The fastening force size that those skilled in the art's fastener 4 as needed provides, it is even more to can be set three through-holes, this Apply without limitation, the transformation of all number of openings belongs to the protection scope of the application.

As Figure 2-3, cavity 2 includes the first cavity and the second cavity of connection, and the cross section of the first cavity is in triangle Shape, the cross section of the second cavity are in rectangle, and the first cavity is formed with opening from the upper surface of substrate, and through-hole is arranged in the second cavity Bottom.First cavity of cavity 2 is set as section inner cavity triangular in shape, and fixed device can be made for fixing sizes Fixture；Second cavity of cavity 2 is set as the inner cavity of rectangular in cross-section, can make supporting element 3 in cavity 2 on move down It is relatively stable when dynamic, it is not susceptible to the case where shaking.

Further, the junction of the first cavity and the second cavity is formed with step surface.The setting of step surface, so that first The inner cavity of cavity is larger, and supporting element 3 on the one hand can be made towards the mobile longer distance of opening, meet consolidated lesser to size Determine the fastening of part；On the other hand, the fastening to the fixture of larger size may be implemented in biggish inner cavity.

Further, clearance fit is formed at supporting block 32 and the second cavity, makes the width and the second cavity of supporting block 32 Width it is substantially consistent.After supporting block 32 is installed in cavity 2, it is not likely to produce shaking, it can be steadily by fixture 5 Fastening is on substrate 1.

Specifically, cavity 2 runs through the corresponding two side walls of substrate 1, can insert from any side in the two sides of cavity 2 Enter supporting element 3 and fixture 5.

As shown in Figure 1, be set in parallel on substrate 1 there are five cavity 2, supporting element 3 and tight is provided in each cavity 2 Firmware 4 can fasten five fixtures 5 simultaneously, and then process simultaneously to five fixtures 5, improve fixture 5 The efficiency of processing.

Optionally, as shown in figure 4, being provided with a cavity 2 on substrate 1.Those skilled in the art are as needed to same The quantity of cavity 2 on substrate 1 is selected, and the transformation of these all 2 quantity of cavity belongs to the protection scope of the application.

Although being described in detail by some specific embodiments of the example to the utility model, this field It is to be understood by the skilled artisans that above example merely to be illustrated, rather than in order to limit the scope of the utility model.This Field it is to be understood by the skilled artisans that can not depart from the scope of the utility model and spirit in the case where, to above embodiments It modifies.The scope of the utility model is defined by the following claims.
