The driving member 14 is connected to the pull rod 10, and is used for driving the pull rod 10 to move in a direction of making the first pressing surface 113 and the third pressing surface 123 approach the first workpiece 300 and the second workpiece 400 to be clamped.
In the implementation process of the clamping mechanism 100 provided in this embodiment, the driving element 14 drives the pull rod 10 to move, so as to drive the first clamping element 11 and the second clamping element 12 to move toward the corresponding first workpiece 300 and the corresponding second workpiece 400, respectively, so that the first pressing surface 113 of the first clamping element 11 contacts with the top surface 301 of the first workpiece 300, at this time, the first clamping element 11 slightly deflects under the action of the elastic element 13, so that the first pressing surface 113 is not parallel to the top surface 301 of the first workpiece, and therefore the first pressing surface 113 is not completely pressed on the top surface 301 of the first workpiece at this time; similarly, the third pressing surface 123 of the second clamping member 12 is in contact with the top surface 401 of the second workpiece 400 and is not completely pressed against the second workpiece top surface 401; with the continued movement of the pull rod 10, under the abutting action of the top surface 301 of the first workpiece against the first pressing surface 113 and the top surface 401 of the second workpiece against the third pressing surface 123, the first clamping member 11 and the second clamping member 12 rotate while opposing the elastic member 13, so that the first pressing surface 113 is completely pressed against the top surface 301 of the first workpiece 300 by the rotation of the first clamping member 11, the second pressing surface 114 is pressed against the side surface 302 of the first workpiece 300 by the rotation of the first clamping member 11, the third pressing surface 123 is completely pressed against the top surface 401 of the second workpiece 400 by the rotation of the second clamping member 12, and the fourth pressing surface 124 is pressed against the side surface 402 of the second workpiece 400 by the rotation of the second clamping member 12. In this way, the first clamping member 11 and the second clamping member 12 can sequentially press the first workpiece 300 and the second workpiece 400 from two directions to fix the workpieces by moving the pull rod 10, so that the workpieces can be fixed by a simple mechanical structure.
In this embodiment, the first body portion 110 is provided with an accommodating groove 115, the second body portion 120 of the second clamping member 12 and the elastic member 13 can be accommodated in the accommodating groove 115, the first clamping member 11 is provided with a first blind hole 115 on a side wall of the accommodating groove 115, the second clamping member 12 is provided with a second blind hole 125 at a position corresponding to the first blind hole 115, and two ends of the elastic member 13 are respectively disposed in the first blind hole 115 and the second blind hole 125 for abutting against the first clamping member 11 and the second clamping member 12 to rotate around the rotating shaft 15.
Thus, the elastic member 13 can be firmly fixed between the first and second clamping members 11, 12, and the elastic member 13 is prevented from being displaced during the operation of the clamping mechanism 100.
In the present embodiment, the clamping mechanism 100 is provided with a first clamping member 11 and a second clamping member 12 for fixing the first workpiece 300 and the second workpiece 400, respectively. In other embodiments, the clamping mechanism 100 may be provided with only the first clamping member 11 or only the second clamping member 12, so as to fix only the first workpiece 300 or the second workpiece 400, according to actual requirements. Here, only the first clamping member 11 is provided as an example: when the clamping mechanism 100 only includes the first clamping member 11, the elastic member 13 may be configured such that one end is connected to the first clamping member 11, and the other end is connected to the pull rod 10, so that when the first clamping member 11 is driven by the pull rod 10 to move toward the first workpiece 300, the first pressing surface 113 of the first pressing portion 111 can partially abut against the first workpiece 300, and then the first clamping member 11 rotates while opposing the elastic member 13 under the abutting action of the first workpiece 300 until the first pressing surface 113 and the second pressing surface 114 are completely pressed against different sides of the first workpiece 300, and the first workpiece 300 is pressed from two directions.
Thus, when only one workpiece needs to be fixed, the structure of the clamping mechanism 100 can be adjusted according to actual requirements, so that only one clamping piece is arranged, the structure is simplified, and the cost is reduced.
In this embodiment, a spring is used as the elastic member 13, and both ends of the spring are respectively disposed on the first clamping member 11 and the second clamping member 12 to push the first clamping member 11 and the second clamping member 12 to rotate toward the corresponding workpieces.

Further, the clamping mechanism 100 provided with only the first clamping member 11 described above is taken as an example: a torsion spring sleeved on the rotating shaft 15 is used as the elastic member 13, and two ends of the torsion spring respectively abut against the first clamping member 11 and the pull rod 10 to push the first clamping member 11 to rotate toward the first workpiece 300, so that the first pressing surface 113 is not parallel to the top surface 301 of the first workpiece 300, when the pull rod 10 moves, the first pressing surface 113 first partially contacts with the top surface 301 of the first workpiece 300, then the first pressing surface 113 gradually and completely presses against the top surface 301 of the first workpiece 300 along with the rotation of the first clamping member 11 while opposing against the torsion spring, and the second pressing surface 114 gradually and completely presses against the side surface 302 of the first workpiece 300.
In this way, in actual production, different forms of elastic members 13 can be used according to different requirements and different working environments, and the elastic members 13 ensure that the first clamping member 11 and the second clamping member 12 in the clamping mechanism 100 deflect respectively until the first pressing surface 113 and the third pressing surface 123 are not parallel to the top surfaces 301 and 401 of the first and second workpieces when the first and second workpieces 300 and 400 are not in contact with each other; when the clamping mechanism 100 works, the first clamping member 11 and the second clamping member 12 are driven by the pull rod 10 to move to the first pressing surface 113, the third pressing surface 123 is not parallel to the top surfaces 301 and 401 of the first and second workpieces and is in contact with the workpieces, along with further movement of the pull rod 10, the first clamping member 11 and the second clamping member 12 resist the elastic member 13 and rotate simultaneously under the abutting action of the top surfaces 301 and 401 of the first and second workpieces until the first pressing surface 113 rotates to be parallel to the top surface 301 of the first workpiece and is completely pressed on the top surface 301 of the workpiece 300, the second pressing surface 114 rotates to be parallel to the side surface 302 of the first workpiece and is pressed on the side surface 302 of the first workpiece 300, the third pressing surface 123 rotates to be parallel to the top surface 401 of the second workpiece and is completely pressed on the top surface 401 of the second workpiece 400, and the fourth pressing surface 124 rotates to be parallel to the side surface 402 of the second workpiece and is pressed on the side surface 402 of the second workpiece 400.
In the present embodiment, the first clamping member 11, the second clamping member 12, and the elastic member 13 are connected to each other through the receiving slot 115, the first blind hole 115, and the second blind hole 125, in other embodiments, for example, in an embodiment in which the elastic member 13 is implemented as a torque spring, other connection manners may also be used between the first clamping member 11, the second clamping member 12, and the elastic member 13, for example, the first clamping member 11, the elastic member 13, and the second clamping member 12 are sequentially sleeved on the rotating shaft 15, wherein the first clamping member 11 and the second clamping member 12 have substantially the same structure, and rotate under the abutting action of the elastic member 13.
