[0035] Embodiment 1

[0036] like Figure 1-5 As shown, a clamp provided by the first embodiment of the utility model has a first direction X, and the clamp includes a clamping mechanism 1, a connecting rod mechanism 2 and a driving mechanism 3; the clamping mechanism 1 includes a first clamping arm 11, a second clamping arm 12 and a first connecting shaft 13, the first clamping arm 11 and the second clamping arm 12 are hinged through the first connecting shaft 13, and the first clamping arm 11 and the second clamping arm 12 are arranged in a cross form; the connecting rod mechanism 2 includes a first connecting rod 21, a second connecting rod 22 and a second connecting shaft 23, the second connecting shaft 23 is located on one side of the first connecting shaft 13, and the first connecting rod 21 is hinged at both ends to the first clamping arm 11 and the second connecting shaft 23 respectively The two ends of the second connecting rod 22 are respectively hinged to the second clamping arm 12 and the second connecting shaft 23; the driving mechanism 3 includes a bracket 31, a mounting member 32, a connecting member 33 and an operating member 34, the first connecting shaft 13 is connected to the bracket 31, the mounting member 32 and the bracket 31 are fixedly connected and are located on the side of the second connecting shaft 23 away from the first connecting shaft 13, the mounting member 32 is provided with a channel 321 passing through along the first direction X, the connecting member 33 is penetrated by the channel 321, one end of the connecting member 33 in the first direction X is connected to the second connecting shaft 23, and the operating member 34 is connected to one end of the connecting member 33 in the first direction X away from the second connecting shaft 23.

[0037] Based on this technical solution, the first clamping arm 11, the second clamping arm 12, the first link 21 and the second link 22 are hinged to each other through the first connecting shaft 13 and the second connecting shaft 23. The second connecting shaft 23 and the first connecting shaft 13 move away from each other, which can reduce the angle between the first link 21 and the second link 22, so that the first link 21 and the second link 22 can drive the angle between the first clamping arm 11 and the second clamping arm 12 to decrease. The first clamping arm 11 and the second clamping arm 12 with the decreased angle can clamp and fix the object located between the first clamping arm 11 and the second clamping arm 12. Similarly, the second connecting shaft 23 and the first connecting shaft 13 approach each other, which can increase the angle between the first clamping arm 11 and the second clamping arm 12. The first clamping arm 11 and the second clamping arm 12 with the increased angle can release the object located between the first clamping arm 11 and the second clamping arm 12. By connecting the first connecting shaft 13 to the second connecting shaft 23 On the bracket 31, the first connecting shaft 13 can be located in a fixed position. By inserting the connecting piece 33 into the channel 321 and connecting the two ends of the connecting piece 33 to the second connecting shaft 23 and the operating piece 34 respectively, the staff can hold the outer wall of the end of the mounting piece 32 close to the operating piece 34 with one hand, and use the operating piece 34 with the other hand to drive the connecting piece 33 to move along the first direction X, so as to drive the second connecting shaft 23 away from the first connecting shaft 13 or close to the first connecting shaft 13. In the above operation, the longer the length of the mounting piece 32 in the first direction X, the longer the operating distance of the clamp can be. Therefore, the clamp provided by the utility model can have a longer operating distance through the coordinated cooperation among the first connecting rod 21, the second connecting rod 22, the second connecting shaft 23, the bracket 31, the mounting piece 32, the connecting piece 33 and the operating piece 34, and is suitable for more application scenarios, has a wide range of applications, and is easy to use.

[0038] The clamp provided by the utility model can be suitable for application scenarios where workers are required to clamp objects from a distance away from the objects, such as application scenarios where it is necessary to clamp a battery cell of unknown status after testing in an explosion-proof box. It has high safety and is easy to use.

[0039] Specifically, the connection method of the clamping mechanism 1 and the connecting rod mechanism 2 is: the first connecting rod 21 has a relative first connecting end 211 and a second connecting end 212, the first connecting end 211 and an end of the first clamping arm 11 close to the second connecting shaft 23 are hinged, the second connecting rod 22 has a relative third connecting end 221 and a fourth connecting end 222, the third connecting end 221 and an end of the second clamping arm 12 close to the second connecting shaft 23 are hinged, and the second connecting end 212 and the fourth connecting end 222 are hinged through the second connecting shaft 23.

[0040] See also Figure 1The clamp also has a second direction Y, which intersects with the first direction X; the driving mechanism 3 also includes a stopper 35, which is fixedly connected to the connecting member 33, and has a stopper end 351; the mounting member 32 is provided with a limiting groove 322 connected to the channel 321 in the second direction Y, and the stopper end 351 is located in the limiting groove 322 or extends to the outside of the channel 321 through the limiting groove 322. By fixing the stop member 35 on the mounting member 32 and connecting member 33 and setting the stop end 351 of the stop member 35 in the limiting groove or extending it to the outside of the channel 321 through the limiting through groove 322, when the connecting member 33 moves to the specified position along the first direction X, the inner side wall of the limiting through groove 322 will contact the stop member 35 so that the movement of the connecting member 33 will be blocked by the stop member 35. Therefore, the stop member 35 can be used to limit the moving distance of the connecting member 33, thereby limiting the opening and closing degree between the first clamp arm 11 and the second clamp arm 12.

[0041] In this embodiment, the first direction X and the second direction Y are perpendicular to each other, and the first direction X and the second direction Y are respectively the length direction and the width direction of the clamp.

[0042] See also Figure 1-Figure 3 The first clamping arm 11 includes a first clamping portion 111 and a first connecting portion 112, the first clamping portion 111 has a first clamping groove 1110, the first connecting portion 112 is connected to one end of the first clamping portion 111, and the first connecting end 211 is hinged to an end of the first connecting portion 112 away from the first clamping portion 111; the second clamping arm 12 includes a second clamping portion 121 and a second connecting portion 122, the second clamping portion 121 has a second clamping groove 1210 opposite to the first clamping groove 1110, the second connecting portion 122 is connected to one end of the second clamping portion 121, the third connecting end 221 is hinged to an end of the second connecting portion 122 away from the second clamping portion 121, and the first connecting portion 112 and the second connecting portion 122 are hinged through a first connecting shaft 13. The first clamping portion 111 and the second clamping portion 121 are respectively provided with a first clamping groove 1110 and a second clamping groove 1210, which can increase the contact area between the clamping surfaces of the first clamping portion 111 and the second clamping portion 121 and the workpiece, thereby providing a more uniform and stable clamping force, which is beneficial to reducing the sliding or falling of the workpiece during the clamping process and improving the reliability of clamping.

[0043] The mutual distance between the second connecting shaft 23 and the first connecting shaft 13 can reduce the angle between the first connecting portion 112 and the second connecting portion 122. The first connecting portion 112 and the second connecting portion 122 with the reduced angle will make the first clamping portion 111 and the second clamping portion 121 approach each other and clamp the article between the first clamping portion 111 and the second clamping portion 121; similarly, the mutual proximity between the second connecting shaft 23 and the first connecting shaft 13 can increase the angle between the first connecting portion 112 and the second connecting portion 122, thereby making the first clamping portion 111 and the second clamping portion 121 move away from each other and loosen the article between the first clamping portion 111 and the second clamping portion 121.

[0044] The first clamping portion 111 includes a first clamping section 1111, a second clamping section 1112 and a third clamping section 1113. The two ends of the second clamping section 1112 are respectively connected to the first clamping section 1111 and the third clamping section 1113. The first connecting portion 112 is connected to one end of the first clamping section 1111 away from the second clamping section 1112. The first clamping section 1111, the second clamping section 1112 and the third clamping section 1113 form a first clamping groove 1110. The second clamping section 1112 is an arc-shaped structure. The second clamping portion 121 includes a fourth clamping section 1211, a fifth clamping section 1212 and a sixth clamping section 1213. The two ends of the fifth clamping section 1212 are respectively connected to the fourth clamping section 1211 and the sixth clamping section 1213. The second connecting portion 122 is connected to one end of the fourth clamping section 1211 away from the fifth clamping section 1212. The fourth clamping section 1211, the fifth clamping section 1212 and the sixth clamping section 1213 form a second clamping groove 1210. The fifth clamping section 1212 is an arc-shaped structure. The arc-shaped structure of the second clamping section 1112 and the fifth clamping section 1212 can reduce the stress concentration phenomenon of the first clamping groove 1110 and the second clamping groove 1210 during the clamping process, which helps to extend the service life of the first clamping arm 11 and the second clamping arm 12 and reduce damage or failure caused by stress concentration.

[0045] See also Figure 1 , Figure 4 and Figure 5 The outer wall of the connecting member 33 is provided with a first external thread 331, and the connecting member 33 is provided with a connecting hole 332, and the connecting member 33 is connected to the second connecting shaft 23 through the connecting hole 332. The connecting hole 332 is connected to the second connecting shaft 23, so as to facilitate the assembly between the connecting member 33, the first connecting rod 21 and the second connecting rod 22.

[0046] A second internal thread 3211 is provided on the inner wall of the channel 321 .

[0047] The operating member 34 includes a matching portion 341 and a handle portion 342. The matching portion 341 is connected to one end of the connecting member 33 away from the second connecting shaft 23 in the first direction X. The handle portion 342 is fixedly connected to the matching portion 341 and is located on a side of the mounting member 32 away from the second connecting shaft 23. The matching portion 341 and the handle portion 342 are used and the handle portion 342 is arranged on a side of the mounting member 32 away from the second connecting shaft 23, so that the staff can drive the connecting member 33 to move by operating the handle portion 342, which is convenient for use.

[0048] The mating portion 341 is provided with a thread groove 3411, the inner wall of the thread groove 3411 is provided with a first internal thread 3412 that matches the first external thread 331, and the outer wall of the mating portion 341 is provided with a second external thread 3413 that matches the second internal thread 3211. The rotation direction of the first external thread 331 is opposite to that of the second external thread 3413. In this way, when the staff rotates the handle portion 342 to drive the matching portion 341 to rotate, the matching portion 341 can drive the connecting member 33 to move along the first direction X, and since the connecting member 33 is connected to the second connecting shaft 23, the first connecting shaft 13 is connected to the bracket 31, and the bracket 31 and the mounting member 32 are fixedly connected, the connecting member 33 will not rotate under the limitation of the above connection; the staff rotates the handle portion 342 to drive the connecting member 33 to move along the first direction X, so as to drive the second connecting shaft 23 away from the first connecting shaft 13, so that the first connecting rod 21 and the second connecting rod 22 can drive the first clamping arm 11 and the second clamping arm 12 to clamp the object, and the second connecting shaft 23 is in the preset position at this time. In the absence of external force to rotate the handle portion 342, the self-locking property of the threaded fit can lock the second connecting shaft 23 in the preset position and fix the relative distance between the second connecting shaft 23 and the first connecting shaft 13, so as to fix the clamping force of the first clamping arm 11 and the second clamping arm 12 on the object, thereby realizing stable clamping of the object by the clamping mechanism 1.

[0049] Preferably, the first external thread 331 is a right-handed external thread, and the second external thread 3413 is a left-handed external thread. The first external thread 331 is set as a right-handed external thread, so that the first external thread 331 and the first internal thread 3412 are connected by a positive thread, and the second external thread 3413 and the second internal thread 3211 are connected by a reverse thread. The staff can drive the connecting member 33 to drive the second connecting shaft 23 away from the first connecting shaft 13 by turning the handle in a clockwise direction, so that the first clamp arm 11 and the second clamp arm 12 clamp and fix the object, which is in line with the operating habits and easy to use.

[0050] In some other implementations, the first external thread 331 may be a left-handed external thread, and the second external thread 3413 may be a right-handed external thread, which is not limited here.

The first guide member 41 can play a guiding role in the movement of the first clamp arm 11 through the first guide slot 1121, and can play a guiding role in the movement of the second clamp arm 12 through the second guide slot 1221 and the second guide member 43.

[0053] Specifically, the first guiding through groove 1121 is provided on the first connecting portion 112 , and the second guiding through groove 1221 is provided on the second connecting portion 122 .

[0054] The guide mechanism 4 further includes a first stopper 42 and a second stopper 44. The first stopper 42 is connected to the first guide member 41.
