According to one embodiment, the first and second clamp arms 11 and 13 are rotatably connected to the mounting base 2. The gripper mechanism 1 further comprises a connecting arm 12 connected between the first gripper arm 11 and the second gripper arm 13, as shown in fig. 5 to 7. That is, one end of the connecting arm 12 is rotatably connected to the first holding arm 11, and the other end of the connecting arm 12 is provided with a connecting portion 121 (please refer to fig. 13 and 15), and the connecting arm 12 is rotatably connected to the second holding arm 13 through the connecting portion 121. When the first clamping arm 11 rotates, the first clamping arm 11 can pull the connecting arm 12 to rotate, the connecting arm 12 drives the second clamping arm 13 to rotate, so that the second clamping arm 13 can rotate towards the direction close to the first clamping arm 11, the distance or the space between the first clamping arm 11 and the second clamping arm 13 is reduced, and further, the first clamping arm 11 and the second clamping arm 13 can respectively tightly abut against the joint 200 and clamp the joint 200 together. In this embodiment, the first clamping arm 11, the connecting arm 12 and the second clamping arm 13 are connected in sequence to form a linkage structure, so that the first clamping arm 11 and the second clamping arm 13 can simultaneously act to clamp the joint 200 only by shifting the first clamping arm 11, which can simplify the operation of the joint fixing device 100, and the joint fixing device 100 is more convenient to use.

Specifically, the first holding arm 11, the connecting arm 12, and the second holding arm 13 are rotated in the same plane or planes parallel to each other. This has the advantage of facilitating the connection and linkage between the first holding arm 11, the connecting arm 12 and the second holding arm 13.

Referring to fig. 1 and 5, according to an embodiment, the mounting base 2 includes a first mounting part 21 and a second mounting part 22, the first mounting part 21 can be fixedly mounted on the object 300 to be mounted, the second mounting part 22 is fixedly connected with the first mounting part 21, and a receiving space (not shown) for receiving the clamping mechanism 1 is formed between the second mounting part 22 and the first mounting part 21. The first mounting part 21 and the second mounting part 22 are both provided with the mounting holes 20 for the joint 200 to penetrate through, and the mounting holes 20 of the first mounting part 21 correspond to the mounting holes 20 of the second mounting part 22 in position. That is, when the connector 200 is connected to the interface 301, the connector 200 is inserted into the mounting hole 20 of the first mounting device 21 and the mounting hole 20 of the second mounting device 22. In this way, the joint 200 simultaneously passes through the mounting hole 20 of the first mounting member 21 and the mounting hole 20 of the second mounting member 22, and is clamped by the clamping mechanism 1 between the first mounting member 21 and the second mounting member 22.

Specifically, the second mounting part 22 and the first mounting part 21 are spaced apart from each other to form an accommodating space therebetween, which can accommodate the clamping mechanism 1.

In the embodiment shown in fig. 5 in particular, the first mounting element 21 and the second mounting element 22 are both plate-shaped, the first mounting element 21 and the second mounting element 22 being arranged spaced apart and parallel to each other.

Specifically, in one embodiment, when the mount 2 is mounted on the object 300 to be mounted, the first mounting part 21 is relatively close to the object 300 to be mounted, and the second mounting part 22 is relatively far from the object 300 to be mounted.

On the basis, please refer to fig. 5, the connector fixing device 100 further includes a fastener 3, and the fastener 3 mounts the mounting base 2 on the object 300 to be mounted.

Specifically, as shown in fig. 5 and 7, the first mounting part 21 is provided with a locking hole 210, and the fastener 3 can pass through the locking hole 210 to lock the first mounting part 21 to the object 300 to be mounted, that is, the fastener 3 fixedly mounts the first mounting part 21 on the object 300 to be mounted.

Referring to fig. 5 and 6, the second mounting member 22 is provided with an avoiding portion 224, and the position of the avoiding portion 224 corresponds to the position of the locking hole 210, so that the fastener 3 can penetrate into the locking hole 210 from one side of the second mounting member 22, and the joint fixing device 100 can be conveniently mounted on the object 300 to be mounted. This has the advantage that the fastener 3 does not have to be arranged to protrude from the second mounting member 22, and the joint fixture 100 as a whole is more compact. In a specific application, the relief portion 224 may be a through hole formed in the second mounting element 22, or may be a notch formed at an edge of the second mounting element 22, and the form of the relief portion 224 is not particularly limited.

Of course, it is understood that it is also possible to mount the mount 2 to the object 300 by the first mounting member 21 being away from the object 300 and the second mounting member 22 being close to the object 300. Correspondingly, the locking hole 210 can be formed on the second mounting member 22, and the fastener 3 can be passed through the locking hole 210 to lock the second mounting member 22 to the object 300 to be mounted. The escape portion 224 may be formed on the first mounting member 21, and the description thereof is omitted.

Referring to fig. 5, 8 and 9, according to an embodiment, a first connecting shaft 221 and a second connecting shaft 222 are disposed on a side of the second mounting member 22 close to the first mounting member 21. Referring to fig. 10, a connection hole 110 is formed at one end of the first clamping arm 11 for the first connection shaft 221 to pass through, the first connection shaft 221 passes through the connection hole 110 to rotatably connect the first clamping arm 11 and the second mounting member 22, and further, the first clamping arm 11 can rotate on the second mounting member 22 with the central axis of the first connection shaft 221 as the central axis. The other end of the first clamping arm 11 is a free end for an operator to apply force to toggle.

The first clamping arm 11 is further provided with a mounting shaft 111, the mounting shaft 111 is located between the free end of the first clamping arm 11 and the connecting hole 110, and one end of the connecting arm 12, which is far away from the connecting portion 121, is rotatably connected with the mounting shaft 111. Specifically, one end of the connecting arm 12 away from the connecting portion 121 is provided with a first rotating hole 120, as shown in fig. 13 and 15, the mounting shaft 111 penetrates through the first rotating hole 120 and is rotatably connected to the connecting arm 12, and the other end of the connecting arm 12 is rotatably connected to the second clamping arm 13 via the connecting portion 121. Thereby, a connection is achieved between the connecting arm 12 and both the first clamping arm 11 and the second clamping arm 13, which allows the connecting arm 12 to be rotated by the first clamping arm 11 and further the second clamping arm 13 to be rotated by the connecting arm 12.

Referring to fig. 11 and 12, one end of the second clamping arm 13 is rotatably connected to the second connecting shaft 222, and the connecting arm 12 is rotatably connected to one end of the second clamping arm 13 away from the second rotating shaft 222 through the connecting portion 121. Specifically, a second rotating hole 130 is formed at one end of the second clamping arm 13 away from the connecting arm 12, and the second connecting shaft 222 on the second mounting member 22 is inserted into the second rotating hole 130, so that the second clamping arm 13 is rotatably connected with the second mounting member 22. As shown in fig. 6 and 7. By means of the arrangement of the first connection shaft 221 and the second connection shaft 222, neither the first holding arm 11 nor the second holding arm 13 can be separated from the second mounting member 22, that is, the holding mechanism 1 cannot be separated from the mounting base 2.

Referring to fig. 6, when the free end of the first clamping arm 11 is shifted from the position shown in fig. 6 counterclockwise (based on the direction of the paper in fig. 6), since the mounting shaft 111 is located between the free end of the first clamping arm 11 and the connecting hole 110, the mounting shaft 111 is driven to rotate counterclockwise and upward with the first connecting shaft 221 as the rotating shaft, so that the end of the connecting arm 12 away from the connecting portion 121 rotates upward, correspondingly, the connecting portion 121 of the connecting arm 12 rotates downward, and the second clamping arm 13 is driven to rotate downward. At this time, the first holding arm 11 and the second holding arm 13 are relatively far away from each other, that is, the connector 200 cannot be held at this time, and the originally held connector 200 can be released, and at this time, the connector fixing device 100 is in a non-holding state. When the non-clamping state needs to be changed into the clamping state, the first clamping arm 11 is applied with force in the downward direction, the free end of the first clamping arm 11 rotates clockwise and downward by taking the first connecting shaft 221 as a rotating shaft, the end of the connecting arm 12 far away from the connecting part 121 rotates downward, the connecting part 121 of the connecting arm 12 rotates upward, the second clamping arm 13 is driven to rotate upward by taking the second connecting shaft 222 as a rotating shaft, and at the moment, the first clamping arm 11 and the second clamping arm 13 are relatively close to each other and are respectively in tight abutting joint with the joint 200 passing through the mounting hole 20, so that the joint 200 is clamped.

Referring to fig. 13 and 14, in an embodiment, the connecting portion 121 is a through hole opened at an end of the connecting arm 12 far from the first clamping arm 11, and referring to fig. 11 and 12, a convex pillar 131 is formed on the second clamping arm 13, and the convex pillar 131 can rotatably penetrate through the connecting portion 121, so that the second clamping arm 13 is rotatably connected with the connecting arm 12. In this embodiment, the connecting portion 121 is provided to ensure that the second clamping arm 13 and the connecting arm 12 are always connected.

Further, the connecting portion 121 is a circular through hole, the protruding pillar 131 on the second clamping arm 13 is cylindrical, and the diameter of the protruding pillar 131 is smaller than the aperture of the connecting portion 121, so that the protruding pillar 131 has a certain moving space in the connecting portion 121, thereby facilitating the linkage operation of the clamping mechanism 1.

It should be noted that the connecting portion 121 is not limited to the form of the through hole, and in another embodiment, as shown in fig. 15 and 16, the connecting portion 121 is a hook-shaped structure formed at an end of the connecting arm 12 far from the first holding arm 11, and the connecting portion 121 can hook the convex pillar 131, so that the connecting arm 12 can drive the second holding arm 13 to rotate, especially to rotate towards the direction close to the mounting hole 20. In this embodiment, the connecting arm 12 needs to be hooked by the hook-shaped structure to the second holding arm 13 during the rotation process. Compared with the hook-shaped structure, the through-hole-shaped connecting part 121 is more convenient to lock, the through-hole-shaped connecting part 12 can be kept connected with the second clamping arm 13 even when the connector fixing device 100 does not clamp the connector 200, the connecting part 12 of the hook-shaped structure needs to be connected with the second clamping arm 13 firstly when the through-hole-shaped connecting part 12 is used for locking, the operation is complicated relative to the through-hole-shaped connecting part 121, the connecting part 12 of the form is easy to loosen from the second clamping arm 13 during the rotation process, and the connecting part 121 of the hook-shaped structure is more convenient to manufacture compared with the through-hole-shaped connecting part 121.

Referring to fig. 5 to 7, according to an embodiment, a positioning column 223 is further disposed between the first mounting member 21 and the second mounting member 22, and the free end of the first clamping arm 11 can abut against the positioning column 223 to prevent the first clamping arm 11 from rotating. The positioning post 223 limits the rotation limit position of the first holding arm 11, so that the first holding arm 11 can only rotate outwards on a side of the positioning post 223 far away from the mounting hole 20.

Specifically, the positioning column 223 may be formed on the first mounting member 21 or on the second mounting member 22. This is substantially the same, and the abutting of the first clamping arm 11 is not affected, and will not be described again. In the present embodiment, the positioning column 223 is formed on the second mount 22, as shown in fig. 8 and 9. In this way, the first mounting member 21 as a whole can be made as flat as possible, facilitating its manufacture.

Referring to fig. 8 and 9, in an embodiment, an end of the positioning column 223 far away from the second mounting part 22 abuts against the first mounting part 21, a third connecting shaft 226 is further formed on a side of the second mounting part 22 facing the first mounting part 21, and an end of the third connecting shaft 226 far away from the second mounting part 22 abuts against the first mounting part 21, so that an accommodating space between the first mounting part 21 and the second mounting part 22 is maintained through the positioning column 223 and the third connecting shaft 226 for the clamping mechanism 1 to be mounted and for the clamping mechanism 1 to perform its operation. The third connecting shaft 226 and the positioning column 223 are formed with a hole structure such as a screw hole at an end away from the second mounting member 22, and are connected to the first mounting member 21 by a locking structure such as a screw (not shown). In other words, the third connecting column 226 not only plays a role of maintaining the accommodating space for installing the clamping mechanism 1, but also assists in achieving the fixed connection of the first mounting part 21 and the second mounting part 22; the positioning post 223 not only serves the same function as the third connecting post 226, but also additionally serves to limit the rotation limit of the first clamping arm 11.

It should be noted that the manner of fixedly connecting the first mounting device 21 and the second mounting device 22 is not limited to the above-mentioned manner, and for example, the first mounting device 21 and the second mounting device 22 may be fixedly connected to each other and a gap may be maintained between them by directly connecting the first mounting device 21 and the second mounting device 22 with bolts, in this case, the positioning column 223 may not contact with the first mounting device 21, may contact with the first mounting device 21, and the third connecting column 226 may be provided or omitted.

Also, since the side of the second mounting part 22 away from the first mounting part 21 faces outward when in use, by providing the third connecting shaft 226 and the positioning column 223 on the second mounting part 22, the screw for fixedly connecting the first mounting part 21 and the second mounting part 22 is not visible from the side of the second mounting part 22 away from the first mounting part 21.

As shown in fig. 6 and 10, a recess 113 is further formed on the first clamping arm 11, and when the first clamping arm 11 abuts against the positioning pillar 223, the positioning pillar 223 can be at least partially accommodated in the recess 113. This is advantageous in that the positioning post 223 can limit the position of the first clamping arm 11, and prevent the first clamping arm 11 from shaking in the length direction.

Referring to fig. 10 and fig. 16, in an embodiment, an end of the first clamping arm 11 away from the free end is a cam end 114, the connecting hole 110 is located at the cam end 114, the cam end 114 can abut against the joint 200 and rotate relative to the joint 200 when the first clamping arm 11 rotates, the first clamping arm 11 is further provided with a supporting protrusion 112, and the supporting protrusion 112 can cooperate with the second clamping arm 13 to clamp the joint 200. With such an arrangement, when the first clamping arm 11 and the second clamping arm 13 clamp the connector 200 together, if no external force pushes the free end of the first clamping arm 11, the first clamping arm 11 does not rotate spontaneously without other positioning structures, and the first clamping arm 11 and the second clamping arm 13 can maintain the state of clamping the connector 200.

Wherein when the free end of the first clamping arm 11 is toggled, the cam end 114 correspondingly rotates about the first connecting shaft 221. At the same time, the cam end 114 slides along the surface of the connector 200, so that the holding projection 112 holds the connector 200.

It should be noted that, when the positioning column 223 abuts against the concave portion 113, the concave portion 113 enables the first clamping arm 11 to be as close to the mounting hole 20 as possible when the first clamping arm is in a state of clamping the connector 200, so that the abutting protrusion 112 can be as close to the mounting hole 20 as possible, which is beneficial to ensuring the clamping effect.

Referring to fig. 13, 14 and 17, in an embodiment, when the first and second clamping arms 11 and 13 clamp the joint 200, the first connecting shaft 221 (point a in fig. 17 is a position of the first connecting shaft 221, that is, a position of the connecting hole 110 when the first and second clamping arms 11 and 13 clamp the joint 200), the mounting shaft 111 of the first clamping arm 11 (point C in fig. 17 is a position where the mounting shaft 111 is located when the first and second clamping arms 11 and 13 clamp the joint 200), and the protruding columns 131 of the second clamping arm 13 (point B in fig. 17 is a position where the protruding columns 131 are located when the first and second clamping arms 11 and 13 clamp the joint 200) are arranged in a triangle. Moreover, an included angle between a connection line AB of the convex pillar 131 to the first connection shaft 221 and a connection line AC of the first connection shaft 221 to the mounting shaft 111 is greater than or equal to 135 °, that is, the angle BAC is greater than or equal to 135 °. Correspondingly, point D in fig. 17 is the intersection of the extension of the AB connection line in the locked state and the motion trajectory of point C around point a, and angle DAC is less than or equal to 45 °. This has the advantage of facilitating the application of force and enabling the gripper mechanism 1 to be held in a gripped state and a non-gripped state. When using the connector fixing device 100, an operator needs to poke the free end of the first clamping arm 11 downward with force, the first clamping arm 11 rotates and then abuts against the positioning column 223, and tightly clamps the connector 200, so as to further ensure that the clamping mechanism 1 cannot be loosened without the assistance of external force, and thus the connector 200 cannot be released. When the connector fixing device 100 is not used, an operator needs to forcibly shift the free end of the first clamping arm 11 upward, the first clamping arm 11 rotates and is away from the positioning column 223, the first clamping arm 11 and the second clamping arm 13 release the connector 200, and similarly, the first clamping arm 11 does not automatically fall back without the aid of external force, but always keeps a state of being away from the second clamping arm 13.

Referring to fig. 11 and 12, in an embodiment, the second clamping arm 13 has a clamping surface 134, that is, a surface of the second clamping arm 13 directly contacts the connector 200, when the second clamping arm 13 and the first clamping arm 11 clamp the connector 200 together, the clamping surface 134 abuts against the connector 200, an edge of the clamping surface 134 is recessed to form a step groove 132, and when the mounting base 2 is mounted on the object 300 to be mounted, an edge of the clamping surface 134 formed with the step groove 132 is close to the object 300 to be mounted. Specifically, the edge of the clamping surface 134 near the first mounting member 21 is recessed to form the stepped groove 132. Because the material of the casing of the joint 200 is generally a deformable material such as rubber and plastic, when the first holding arm 11 and the second holding arm 13 tightly hold the joint 200 together, the portion held on the joint 200 is subjected to pressure, so that the surrounding portion slightly expands, the step groove 132 can give room for the expansion portion of the joint 200, and meanwhile, the expansion portion on the joint 200 can abut against the groove wall of the step groove 132 to increase the friction force between the joint 200 and the second holding arm 13, thereby further enhancing the connection between the joint fixing device 100 and the joint 200 and preventing the joint 200 from falling off and moving.

Referring to fig. 8, 9 and 11, in an embodiment, the mounting base 2 is provided with a blocking protrusion 225, as shown in fig. 11, the second clamping arm 13 is provided with a blocking groove 133, and the blocking protrusion 225 can abut against a groove wall of the blocking groove 133 to prevent the second clamping arm 13 from rotating in a direction away from the first clamping arm 11 when the first clamping arm 11 and the second clamping arm 13 do not clamp the connector 200.

In particular, the blocking projection 225 may be provided on the second mount 22; the blocking groove 133 on the second gripper arm 13 is provided on the side of the second gripper arm 13 facing the second mounting part 22. Of course, it is also possible to reverse the arrangement of the blocking projection 225 on the first mounting part 21 and the blocking groove 133 on the second gripper arm 13 on the side of the second gripper arm 13 facing the first mounting part 21. This is not particularly limited as long as the second clamp arm 13 can be blocked between the first mount 21 and the second mount 22.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
