Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] Further, the upper part of the mounting plate 41 is rotatably connected with the connecting plate 42, which functions to change the direction of force when the output shaft of the cylinder 3 is stretched and contracted, and convert the linear motion of the output shaft of the cylinder 3 into the rotary motion of the pressing rod 43, so as to realize the clamping or loosening action of the pressing rod 43 on the tensile sample, while ensuring the stability and flexibility of the pressing rod 43 during the movement. The connecting plate 42 is provided in multiple groups, and the upper part of the output shaft of the cylinder 3 is rotatably connected with the pressing rod 43. The upper part of the connecting plate 42 is rotatably connected to the inner wall of the pressing rod 43. The side of the pressing rod 43 close to the support block 2 is designed in a U shape. The pressing rod 43 is provided in multiple groups, and the multiple groups of pressing rods 43 close to the two sides of the support block 2 are staggered. The uniform clamping force is applied to the tensile sample from multiple directions, so that the multiple groups of pressing rods 43 can simultaneously clamp the tensile sample. The multiple groups of pressing rods 43 are driven to open by one side of the multiple groups of cylinders 3, and the multiple groups of pressing rods 43 are driven to press the tensile sample by the other side of the multiple groups of cylinders 3. This facilitates the fixation of the tensile sample and the grinding processing of the two sides of the tensile sample, thereby improving the work efficiency. At the same time, the overall volume and weight of the equipment are reduced by the multiple groups of pressing rods 43, so that the cost of the equipment is greatly reduced.
[0032] Referring to Figure 2 and Figure 3 , the auxiliary assembly includes a mounting hole 51, which is provided on the upper part of the pressing rod 43 and provides a mounting position for the buffer pad 52, so as to ensure that the buffer pad 52 can be accurately installed at the position where the pressing rod 43 contacts the tensile sample, thereby playing a role of buffering and protecting the tensile sample. The buffer pad 52 is inserted into the inner wall of the mounting hole 51. When the tensile sample is clamped, the buffer pad 52 directly contacts the tensile sample. The buffer pad 52 is made of rubber material, which can increase the friction between the buffer pad 52 and the tensile sample, thereby further improving the fixing stability of the tensile sample. The buffer pad 52 is provided in multiple groups and designed in a U shape, which is matched with the shape of the pressing rod 43, so as to ensure that the buffer pad 52 can fully cover the contact area between the pressing rod 43 and the tensile sample. The upper inner wall of the buffer pad 52 is threadedly connected with a screw 53, which is provided in multiple groups. The screw 53 is rotated in the inner wall of the buffer pad 52, so that the buffer pad 52 is deformed and can be fixed in the mounting hole 51, thereby preventing the buffer pad 52 from loosening or falling off during use, and ensuring that the buffer pad 52 can always play its role of buffering and protection.
[0033] Referring to Figure 1 and Figure 4The inner wall of the supporting block 2 is provided with a limiting assembly, the limiting assembly comprises a pressing rod 73 which is slidingly connected to the inner wall of the supporting block 2 and is used for controlling the movement of a limiting block 74; when it is necessary to install or dismount the mold 6, the pressing rod 73 is pressed to drive the limiting block 74 to slide on the inner wall of the supporting block 2, so that the mold 6 is unlocked or locked, and the mold 6 is conveniently replaced and adjusted; the outer side of the pressing rod 73 is fixedly connected with the limiting block 74, the right side of the limiting block 74 is provided with an inclined surface and is provided with two groups; during the installation of the mold 6, when the inserting column 71 is inserted into the inner wall of the supporting block 2, the inserting column 71 will press the inclined surface of the limiting block 74, so that the limiting block 74 automatically slides downward; after the inserting column 71 is completely inserted, the limiting block 74 is clamped into the clamping groove 72 between the two adjacent groups of the inserting column 71 under the action of the compression spring 75, so that the mold 6 is accurately limited and fixed, and displacement of the mold 6 in the horizontal direction during the processing is prevented.
[0034] Further, the limiting block 74 slides on the inner wall of the supporting block 2, the limiting block 74 and the supporting block 2 are elastically connected through the compression spring 75, the compression spring 75 is sleeved on the periphery of the pressing rod 73, one end of the compression spring 75 is connected to the limiting block 74, and the other end of the compression spring 75 is in contact with the inner wall of the supporting block 2; the compression spring 75 provides an upward elastic force for the limiting block 74, so that the limiting block 74 is kept in the clamping groove 72 when no external force is applied, and the stable fixation of the mold 6 is ensured; when the pressing rod 73 is pressed, the compression spring 75 is compressed, the limiting block 74 slides, and the mold 6 is unlocked, so that the mold 6 can be quickly replaced to adapt to different specifications of the stretching sample, and the practicability of the device is improved; the mold 6 is fixedly connected with the inserting column 71 at the bottom end, the inserting column 71 is inserted into the inner wall of the supporting block 2, the inserting column 71 is provided with a plurality of groups to provide horizontal limiting for the mold 6, and the opposite side of the two adjacent groups of the inserting column 71 is provided with the clamping groove 72; the limiting block 74 slides in the inner wall of the clamping groove 72 and cooperates with the limiting block 74, so that the mold 6 can be quickly unlocked or locked, and the efficiency is improved.
[0035] Working principle: in use, the stretching sample is positioned on the mold 6. Then the cylinder 3 is started, and the extension and retraction movement of the output shaft of the cylinder 3 drives the pressing rod 43 movably connected to the upper part of the cylinder 3. Since the inner wall of the pressing rod 43 is rotatably connected to the mounting plate 41 through a plurality of connecting plates 42, when the output shaft of the cylinder 3 extends and retracts, the connecting plates 42 change the direction of the force to convert the linear motion of the output shaft of the cylinder 3 into the rotary motion of the pressing rod 43, so that the buffer pad 52 at the upper part of the pressing rod 43 directly contacts the stretching sample, prevents damage to the stretching sample, and also increases the friction between the stretching sample and the buffer pad 52, further improves the fixing stability of the stretching sample,
[0036] At this time, by controlling the cylinder 3, a plurality of pressing rods 43 on one side can be driven to open, and a plurality of pressing rods 43 on the other side can be driven to press the stretching sample, so that the stretching sample is conveniently fixed and the two sides of the stretching sample are conveniently ground, and the working efficiency is improved.
[0037] When the mold 6 needs to be replaced to adapt to different specifications of the stretch sample, the pressing rod 73 in the limiting assembly is pressed, the pressing rod 73 drives the two sets of limiting blocks 74 to slide against the elastic force of the compression spring 75, the limiting blocks 74 are separated from the clamping groove 72 of the mold 6 insertion column 71, thereby releasing the locking of the mold 6, and then the mold 6 can be easily pulled out of the supporting block 2 to perform the mold 6 replacement operation.
[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing embodiments of the present application are described in detail, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
