In practice, the device of the present invention can simultaneously clamp and fix the material by the pressing surface 62 and the side clamping surface 61, and it is necessary to keep the horizontal movement and the elevation of the clamping block 6 due to the above special arrangement, and the precision of the horizontal movement and the elevation will greatly affect the fixing effect and the precision of the stamping, and the traditional single clamping structure can set a stable structure in the other clamping direction to prevent the vibration due to the single structure, but the application needs to keep the elevation and the horizontal movement, so that the stabilization in multiple angles will be very complicated and the operation is cumbersome, and the special structure of the application will make the stamping in the clamping and stamping process, although the stamping is performed in the vertical direction, but in the fixed horizontal direction, it also has a relatively large impact, which will make the stamping generate deviation, resulting in the precision reduction, and the deviation will also lead to the dimension measured by the scale mark 17 to be no longer accurate, and simultaneously in practice, because the vibration leads to the vibration and the excursion or even the deformation of the lifting slide rod 2, it also leads to the lateral abnormal movement of the lifting plate seat 9, and leads to the possibility that the lifting inner wire barrel 10 is blocked and difficult to move, for this reason, further improvement is carried out, and the specific scheme is as follows: the two clamping blocks 6 are symmetrically arranged L-shaped steel, the L-shaped steel is provided with a vertical plate 23 and a transverse plate 24 connected with the vertical plate, the inner side of each clamping block 6 is a side clamping surface 61, the bottom surface of each clamping block 6 is a pressing surface 62, a telescopic cylinder 18 is arranged above the lifting plate 9, the upper end of the telescopic cylinder 18 is provided with a through hole with a diameter smaller than that of the telescopic cylinder for supporting, a spring 19 is arranged in the telescopic cylinder 18, the lower end part of the spring 19 is fixedly connected with the bottom of the telescopic cylinder 18, the upper end part of the spring 19 is connected with a stabilizer bar 20, the stabilizer bar 20 penetrates through the through hole, a first magnet 25 is arranged outside the stabilizer bar 20 and above the telescopic cylinder 18, the stabilizer bar 20 further penetrates through the workbench 101, one side, far away from the side clamping surface 61, of the transverse plate of each clamping block 6 is connected with a slide rail 21, one side, far away from the clamping block 6, is connected with a horizontally arranged stabilizer plate 22, the height of the stabilizing plate 22 is smaller than that of the transverse plate, the stabilizing plate 22 can move on the slide rail 21 to adjust the distance between the stabilizing plate 22 and the stabilizer bar 20, a circular groove is formed on the lower side of the stabilizing plate 22, a second magnet 26 is arranged above the stabilizing plate 22, the circular groove matches with the shape of the stabilizer bar 20, an electromagnet is fixedly connected above the telescopic cylinder 18, the electromagnet is in a ring structure with a central circular hole, the diameter of the central circular hole is larger than that of the stabilizer bar 20, a preset distance is formed between the electromagnet and the first magnet 25 in the vertical direction, the second magnet 26 is arranged above the stabilizing plate 22, the acting force between the second magnet 26 and the first magnet 25 is an adsorption force, and it should be noted that the width of the stabilizing plate 22 is actually smaller than that of the transverse plate 24 as shown in fig. 4-5, the stabilizer plate 22 may in practice be located, for example, between two lifting slide bars 2 on the left side of fig. 1, the two lifting slide bars 2 being located outside said stabilizer plate 22. In actual operation, the steps are the same as the above, except that in the process of moving the lifting plate base 9 up and down, the telescopic cylinder 18, the electromagnet, the spring 19 and the stabilizer bar 20 are also driven to move up and down, accordingly, the distance between the stabilizer bar 20 and the stabilizer plate 22 is kept basically constant, the spring 19 is arranged so that the uppermost end of the stabilizer bar 20 can be accommodated in the through hole of the workbench 101 when not being acted by the electromagnet, i.e. the stabilizer bar 20 does not protrude out of the workbench, so that the arrangement of the stabilizer plate 20 does not affect the up and down and left and right movement of the clamping block, when the spring is arranged to be repelled by the electromagnet, the acting force between the electromagnet and the first magnet 25 pushes the first magnet 25 and the stabilizer bar 20 to ascend, so that the stabilizer bar 20 can enter the circular groove of the stabilizer plate for limiting, the distance between the first magnet 25 and the second magnet 26 is reduced, so that the second magnet 26 adsorbs the first magnet to ensure that the stabilizer bar is kept stable in the circular groove, and the elastic force of the spring can be overcome (at the moment, the electromagnet can be removed from repulsion); the spring 19 is arranged to enable the electromagnet to attract the first magnet 25 and descend when the electromagnet is attracted, so that the attraction force between the first magnet and the second magnet is overcome, and the stabilizer bar 20 can be separated from the circular groove to be released from fixation; since the above-mentioned springs are arranged to realize the above-mentioned functions at the same time, the requirement for the elastic accuracy of the springs is very high, and the attenuation of the springs will cause the above-mentioned preset functions to be out of order or to be out of order, for this reason, under the above-mentioned circumstances, the distance between the stabilizing plate 22 and the stabilizing rod 20 is changed by moving the stabilizing plate 22 up and down to adjust, so as to compensate the change of the above-mentioned spring force, once the above-mentioned problem occurs, the above-mentioned functions can be realized again by adjusting the position of the stabilizing plate by the cooperation of the above-mentioned springs 19 and the above-mentioned distance. In summary, the present application can adjust the distance between the stabilizer plate and the stabilizer bar, so that in case of a failure or attenuation of the spring, the damping can be compensated for by the movement of the stabilising plate, either in the case of a fixing of the side clamping or pressing surfaces, the stabilizer bar is inserted into the circular groove below the stabilizer plate, so that the stabilizer bar can realize a very good stabilizing function through the cooperation of the stabilizer bar and the circular groove, prevent vibration in the horizontal direction in the stamping process, avoid the lateral pressure of the vibration on the distance adjusting inner wire barrel, the lifting slide bar and the lifting plate seat, prevent lateral deviation of force, simultaneously effectively prevents the lateral pressure on the lifting inner wire cylinder, reduces the abrasion of the lifting inner wire cylinder, simultaneously, the occurrence of the lifting difficulty caused by abrasion and lateral pressure is avoided, and the control of the stabilizer bar is realized by the cooperation of the first magnet, the second magnet and the electromagnet. The method can be summarized as follows: firstly, the clamping block 6 is controlled to horizontally move to a proper position, then the clamping block 6 is vertically lifted and moved to a proper position, the lifting plate seat 9 is vertically moved to drive the telescopic cylinder 18, the electromagnet, the spring 19 and the stabilizer bar 20 to vertically move, the electromagnet is started to enable repulsive force between the electromagnet and the first magnet 25 to push the first magnet 25 and the stabilizer bar 20 to ascend, the stabilizer bar 20 can enter a circular groove of a stabilizing plate to be limited, the second magnet 26 adsorbs the first magnet 25 to enable the stabilizer bar to be kept and stabilized in the circular groove, after clamping is finished, the electromagnet is started to enable the electromagnet to adsorb the second magnet 25 to enable the second electromagnet to drive the stabilizer bar 20 to be separated from the circular groove to be released from fixation, finally, the electromagnet is powered off, and part of the stabilizer bar 20 is accommodated in the telescopic cylinder 18, this is also one of the important points of the present invention.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
