Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

The first embodiment is as follows:

as shown in fig. 1 and fig. 2, which are schematic structural views of the clamp provided by the present invention. The clamp comprises a clamp body 1 and a feeding piece 2 arranged on the clamp body 1, wherein a plurality of feeding channels 3 are arranged on the clamp body 1, the clamp body 1 is sleeved outside an object to be clamped, and the feeding piece 2 can move telescopically along the feeding channels 3 to clamp the object to be clamped. According to the invention, the plurality of feeding channels 3 and the feeding piece 2 which can telescopically move along the feeding channels 3 are arranged, so that the feeding piece 2 can be used for finding the clamping position of the object to be clamped so as to clamp the object to be clamped, and the problem that the object to be clamped is not firmly fixed in the prior art is solved.

Specifically, feed passageway 3 is three at least, and every feed passageway 3 all is equipped with feeding 2, and locates the upside, the left side and the right side of anchor clamps main part 1 separately to can guarantee feeding 2 and treat the firm fixed of pressing from both sides the thing. In order to further ensure that the clamping device is suitable for objects to be clamped in different shapes, more than three feeding channels 3 are arranged. It is understood that three feeding channels 3 can be provided, and each feeding channel 3 can move on the clamp body 1 in a sliding, rolling or other moving manner. Specifically, the jig main body 1 is provided with a groove (not shown in the figure) along which the feed path 3 can slide, and when the feed path 3 slides to a target position, the feed path 3 is locked. The locking structure may be a protrusion provided on the feeding passage 3 for being snapped into the groove, thereby achieving a locking function. The locking structure is not particularly limited herein as long as a structure having a locking function and adapted to the channel can be satisfied.

Preferably, in the present embodiment, the feed passage 3 takes the form of a plurality of (at least three) straight strips, in which: the feed passage 3 includes a plurality of nuts, the feed member 2 includes a bolt, and the plurality of nuts are welded to the jig main body 1 to be telescopically movable along the nuts by screwing the bolt. The arrangement mode of the thread matching structure is adopted, so that the manufacturing cost of the clamp can be greatly saved, and the processing difficulty of the clamp is reduced. Further, the end of the bolt is provided with a handle 22, and the bolt is moved along the nut by screwing the handle 22.

Specifically, wait to press from both sides the thing and include three proofings cloth 10 and panel 20, three proofings cloth 10 covers on panel 20, and on panel 20 was located to anchor clamps main part 1 cover, feeding piece 2 was used for being fixed in three proofings cloth 10 on panel 20. In FIG. 1, sheet 20 is a T-shaped sheet; in fig. 2, the plate 20 is a gusset plate. According to the specific shape of the plate 20, the feeding channel 3 can reasonably move on the clamp body 1, and the feeding piece 2 can reasonably move on the feeding channel 3.

Specifically, the end of the feeding piece 2 is provided with a cambered cover body 21, and the cambered cover body 21 is in threaded connection or clamping connection with the feeding piece 2, so that the feeding piece 2 is convenient to assemble. Preferably, the cambered surface cover 21 is in threaded connection with the feeding member 2, i.e. can be in threaded connection with the inside or outside of the feeding member 2; when internal, the end or the whole of the feed member 2 is a hollow tube. Through setting up the cambered surface cover body 21, can avoid feeding piece 2 to the point contact or the rigid contact of three proofings cloth 10 to play the better protection to three proofings cloth 10.

Example two:

as shown in fig. 3, the second embodiment is different from the first embodiment in that: the feed channel 3 and the feed member 2 are not screwed but are resiliently connected. Specifically, the feeding channel 3 may be a through hole, and it is sufficient to provide a channel for the feeding element 2 to go in and out, a spring 23 is sleeved outside the feeding element 2, one end of the spring 23 abuts against the inner side of the arc cover 21, and the other end abuts against the clamp body 1 (preferably, the feeding channel 3). In this embodiment, the cambered surface cover 21 is preferably screwed to the inside of the feed member 2, so as to avoid interference of the spring 23 with the screw thread of the feed member 2. In addition, in this embodiment, the cambered surface cover body 21 has another advantage: when the object to be clamped (mainly the plate 10) is touched, the cambered surface cover body 21 can be stressed (namely, has compressive force) according to the shape of the specific plate 10, so that the feeding piece 2 can be more smoothly and conveniently fixed and clamped to the object to be clamped. In particular, the spring 23 is preferably a spring with high elastic stiffness, so that the object to be clamped can be more firmly fixed.

Example three:

as shown in fig. 4 and 5, the present invention also provides a clamp, which comprises a clamp body 1 having an "Ω" shape and made of metal, wherein the clamp body 1 is provided with an opening 11, and the opening 11 is used for clamping an object to be clamped. The length of the opening 11 is preferably smaller than the length of the portion opposite to the opening 11, so as to ensure that the opening 11 has a larger force.

The invention also provides a clamping method, the clamp provided in the first embodiment and the second embodiment is a preferable embodiment of the clamping method, and the clamping method comprises the following steps:

on locating panel 20 with three proofings cloth 10 lid, on panel 20 was located to anchor clamps main part 1 cover, made feeding piece 2 along the scalable removal of anchor clamps main part 1 to make three proofings cloth 10 fix on panel 20.

Specifically, the feeding member 2 is screwed with the jig main body 1; or the feeding member 2 is elastically connected to the jig main body 1.

The invention also provides another clamping method, the clamp provided by the third embodiment is a preferred embodiment of the clamping method, and the clamping method comprises the following steps:

the three-proofing cloth 10 is covered on the plate 20, and the three-proofing cloth 10 is fixed on the plate 20 through the opening of the clamp body 1 in the shape of omega.

By adopting the two clamping methods, the three-proof cloth 10 can be firmly fixed on the plate 20.

It should be understood that the above-described embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art based on the foregoing description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
