Example 3

The embodiment mainly adopts embodiment 2, except that the screw rod adjusting mechanism in the embodiment is further provided with a resetting piece which is arranged between the sliding block 401 and the first telescopic assembly 200 along the axial direction of the adjusting screw rod 400. The return element is preferably configured as a spring, which is directly threaded onto the adjusting screw 400. Compared with the embodiment 2, the first telescopic assembly 200 does not have a free moving stroke, so that the first telescopic assembly 200 can be prevented from being damaged due to noise or collision with other articles caused by free movement when the first telescopic assembly is carried out, but the first telescopic assembly also has many advantages in the embodiment 2, and the practicability is high.

Example 4

The embodiment mainly uses embodiment 2, but the difference is that the screw rod adjusting mechanism in this embodiment only has one adjusting screw rod 400, the adjusting screw rod 400 is rotatably disposed through the limiting plate 106 and the mounting plate 105 of the clamping main body 100, and the first telescopic assembly 200 is provided with a hole matched with the first telescopic assembly and is in threaded connection with the first telescopic assembly. Thus, the first telescopic assembly 200 is controlled to move directly by rotating the adjusting screw rod 400, and the stroke adjustment of the first telescopic assembly 200 is realized.

The structure in this embodiment is simpler than that in embodiment 2, and therefore, the production cost is lower. However, as the adjusting screw rod 400 and the first telescopic assembly 200 are axially pulled, the thread is worn quickly and the service life is short.

Example 5

The present embodiment mainly uses embodiment 2, except that, as shown in fig. 3 and 5, the adjusting screw 400 is provided with an adjusting groove 405 along the circumferential direction, and the central angle corresponding to the adjusting groove 405 is less than 360 °. The clamping body 100 is provided with an adjusting switch 403 which slides left and right along the direction shown in fig. 5, the adjusting switch 403 is provided with a limiting part 406 which is inserted into the adjusting groove 405, and the limiting part 406 can exit from the adjusting groove 405 in the process of moving the adjusting switch 403. Meanwhile, a locking spring 407 is arranged between the clamping main body 100 and the adjusting switch 403.

As shown in fig. 3 and 5, an adjusting sleeve 402 having an outer diameter larger than that of the adjusting screw 400 is disposed at a portion of the adjusting screw 400 corresponding to the mounting plate 105, an adjusting groove 405 is formed in the adjusting sleeve 402, a strip-shaped hole through which the adjusting sleeve 402 can pass and move is formed in the adjusting switch 403, the limiting portion 406 is disposed at the inner side of the strip-shaped hole in a protruding manner, the left end of the adjusting switch 403 penetrates through the clamping body 100 to form a pressing portion 404, and a locking spring 407 is disposed between the right end of the adjusting switch 403 and the clamping body 100.

In this way, in the working process, if the pressing portion 404 is not pressed down, the limiting portion 406 is located in the adjusting groove 405, so that the rotation angle of the adjusting screw rod 400 is limited within the range of the central angle corresponding to the adjusting groove 405, in this case, the adjusting screw rod 400 can realize the fine adjustment function, and the phenomenon that the clamped object is excessively clamped due to excessive rotation of the adjusting screw rod 400 can be avoided. When the adjusting screw rod 400 needs to be rotated within a large range, the pressing part 404 can be pressed down, so that the limiting part 406 exits from the adjusting groove 405. In summary, the safety of the clamping device in the embodiment is higher. The setting of adjusting collar 402 also can strengthen the atress, the life and the stability of extension structure.

Example 6

The present embodiment mainly uses embodiment 5, except that the adjustment groove 405 in the present embodiment is configured as a spiral groove, so as to increase the range in which the adjustment screw 400 can rotate when the limiting portion 406 is accommodated in the adjustment groove 405.

Example 7

The embodiment mainly uses embodiment 5, but the difference is that the adjusting groove 405 in this embodiment is further provided with a fine tuning groove with a smaller central angle range, and the limiting portion 406 can be accommodated in the fine tuning groove. This allows two-stage fine adjustment by depressing the pressing portion 404.

Example 8

The embodiment uses the embodiment 2 as a main body, but the difference is that a first elastic member for driving the first telescopic assembly 200 to contract is disposed between the first telescopic assembly 200 and the clamping main body 100 in the embodiment, and a second elastic member 301 for driving the second telescopic assembly 300 to contract is disposed between the second telescopic assembly 300 and the first telescopic assembly 200. The first elastic member and the second elastic member 301 may be a spring, a tension spring, a torsion spring, a rubber band, or the like.

This enables the folding control of the first and second telescopic assemblies 200 and 300 directly by the first and second elastic members 301. The working mode of the telescopic clamp is almost the same as that of the traditional structure, but the clamping size can be increased by the two-stage telescopic mode, and the application range is enlarged.

Obviously, in the actual production process, a multi-stage telescopic assembly in the form of three stages, four stages and the like can also be arranged.

Example 9

The embodiment uses embodiments 1 to 8 as main bodies, except that, as shown in fig. 6, an adjusting screw 500 is inserted into the clamping main body 100 in the embodiment, an adjusting nut 501 is inserted into the adjusting screw 500, the adjusting nut 501 is exposed on the surface of the clamping main body 100 and is in threaded connection with the adjusting screw 500, so as to control the movement of the adjusting screw 500 by rotation, and the first clamping jaw 101 is fixedly connected with the adjusting screw 500.

In the practical use process, the movement of the first clamping jaw 101 can be adjusted by rotating the adjusting nut 501, so that the size range which can be clamped is further expanded.

And as shown in fig. 6, in an actual production process, two first clamping jaws 101 can be provided, the number of the second clamping jaws 102 is corresponding to that of the first clamping jaws 101, and the distance between two adjacent first clamping jaws 101 and the corresponding second clamping jaws 102 is different, so that a plurality of clamping spaces with different clamping sizes are formed. Therefore, the user can use the first clamping jaw 101 and the second clamping jaw 102 with the adaptive clamping sizes according to actual requirements, and the first clamping jaw 101 and the second clamping jaw 102 which are not needed to be used are rotatably folded. Similarly, when clamping asymmetric articles, the clamping and fixing can be realized by matching the multiple groups of the first clamping jaws 101 and the second clamping jaws 102, so that the practicability is high.

Of course, three or more first clamping jaws 101 may be provided in the actual production process.

Example 10

The embodiment mainly uses the embodiment 2, but the difference is that the rotating and receiving directions of the first clamping jaw 101 and the second clamping jaw 102 in the embodiment are inward rotating and folding as shown in fig. 7.

The telescopic assembly in this embodiment is also different from embodiment 2 in that the second jaw 102 is mounted on the clamping body 100 through a guide rod and a tension spring structure, and the first jaw 101 is mounted on the clamping body 100 through a screw structure, thereby realizing two-stage telescopic adjustment.
