[0049] As mentioned in the background technology, most machines have complex structures and numerous circuits, and in the operation of these precision machines, it is often necessary to accurately connect two connectors within a limited operating space. This space limitation may not only lead to obstructed vision and inability to directly observe the specific position of the connector, but also may be difficult to use both hands due to the small space, greatly increasing the difficulty of operation. For example, the vapor deposition machine in semiconductor production and manufacturing includes a radio frequency connector. Since the radio frequency connector is a quick connector, two connectors need to apply force at the same time to complete the plug-in, and the space where the radio frequency connector is located is relatively small, and it can only be operated with one hand and there is no line of sight. Therefore, there is an urgent need to provide a tool that can achieve connector docking in a small space.

[0050] Based on this, please refer to Figure 1a and Figure 1b The present application provides a clamp, including a jaw portion 11 for rotating with the jaw arm; at least one jaw portion 11 includes a fixing component 110 having a limiting opening 111; the fixing component 110 includes an adjusting portion 113, and the adjusting portion 113 is used to adjust the opening area of ​​the limiting opening 111 and clamp an object (not shown) passing through the limiting opening.

[0051] As an example, the clamp includes a clamp body, and the clamp body includes: a first clamp arm 10 and a second clamp arm 20, the first clamp arm 10 is rotatably connected to the second clamp arm 20, the first end of the first clamp arm 10 and the first end of the second clamp arm 20 respectively form a clamp tooth portion 11, the two clamp tooth portions 11 are relatively spaced, and when the two clamp tooth portions 11 are closed, they can clamp an object, and the second end of the first clamp arm 10 and the second end of the second clamp arm 20 respectively form a handle 12, and the two handles 12 are relatively spaced. In addition, the movement relationship between the handle 12 and the clamp tooth portion 11 may include: when the two handles 12 are closest to each other, the two clamp tooth portions 11 are closed; or when the two handles 12 are farthest apart, the two clamp tooth portions 11 are closed. The present application does not make specific restrictions on the movement relationship between the handle 12 and the clamp tooth portion 11, that is, the structure of the clamp body is not specifically restricted.

[0052] As an example, the opening directions of the limiting openings 111 of the two jaw parts 11 are arranged opposite to each other. The adjusting part 113 may include a tooth part located in the fixing component 110 , and the opening area of ​​the limiting opening 111 is adjusted by extending or retracting into the fixing component 110 .

[0053] In the above embodiment, the clamp includes a jaw portion 11 for rotating with the clamp arm; at least one jaw portion 11 includes a fixing assembly 110 having a limiting opening 111; the fixing assembly 110 includes an adjusting portion 113, and the adjusting portion 113 is used to adjust the opening area of ​​the limiting opening 111 and clamp the object passing through the limiting opening 111. In the present application, the jaw portion 11 that rotates with the clamp arm is set to include a fixing assembly 110 having a limiting opening 111, and the object passing through the limiting opening 111, such as a joint, is clamped through the limiting opening 111 of the fixing assembly 110. Each jaw portion 11 clamps a joint respectively, and then a force is applied to the handle 12 to make the two opposite jaw portions 11 contact, so that the objects fixed by the jaw portions 11 contact each other, thereby achieving the docking of the joints. In addition, the present application can adjust the opening area of ​​the limiting opening 111 through the adjusting portion 113, so as to be applicable to joints of different sizes, thereby broadening the scope of application of the clamp.

[0054] In one embodiment, please refer to Figure 2 The fixing assembly also includes an open ring 115 and a fixing pin 117; a rack is distributed on the surface of the open ring 115; the adjusting portion includes at least two gears 400 and at least two sliders 30; the side wall of the slider 30 includes a toothed structure 301; at least two gears 40 are distributed on the inner side of the open ring 115 at intervals, and are respectively meshed with the toothed structure 301 of the slider 30 and the rack on the inner side of the open ring 115; the slider 30 also includes a slide groove 303 for limiting the moving direction and moving distance of the slider 30, and penetrating the slider 30 along the thickness direction of the slider 30, and the fixing pin 117 is used to penetrate the slide groove 303 and be connected to the open ring 115; the moving direction of the slider 30 intersects with the open ring 115.

[0055] As an example, the opening angle W of the open ring 115 is less than or equal to 180 degrees. For example, the opening angle W of the open ring 115 may include 30 degrees, 40 degrees, 50 degrees, 60 degrees, 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, 180 degrees, etc. The opening angle W of the open ring 115 is associated with the radius of the closed circular ring corresponding to the open ring 115 and the size of the object. When the opening angle W of the open ring 115 is too small, the connected object cannot pass through the opening and separate from the open ring, but when the opening angle W of the open ring 115 is too large, it will affect the stability between the fixed component and the object. The present application does not make specific restrictions on the opening angle W of the open ring 115, and it can be set according to actual needs.

[0056] As an example, the gear 40 and the slider 30 are arranged correspondingly. The slider 30 is movably connected to the open ring 115, and the moving direction of the slider 30 can be toward the center of the open ring 115. The rotating shaft of the gear 40 is fixedly connected to the open ring 115. When any slider 30 moves, the toothed structure 301 of the slider 30 drives the gear 40 corresponding to the slider 30 to rotate, and the gear 40 drives the rack (for example, including the first rack 115c or the second rack 115d) to rotate relative to the open ring 115, thereby driving the remaining gears 40 to rotate, so as to drive the remaining sliders 30 corresponding to the gear 40 to move, and the movement direction of each slider 30 is unified, including: moving in the direction toward the center of the open ring 115, or moving in the direction away from the center of the open ring 115. In addition, the toothed structure 301 of the slider 30 and the rack can be in a non-contact state.

[0057] As an example, the moving direction of the fixing pin 117 intersects with the plane where the open ring 115 is located. When the fixing pin 117 moves to the lowest end of its moving direction, the fixing pin 117 contacts the slider 30, and the slider 30 is fixed. In addition, the fixing assembly may include a fixing pin 117, or the fixing pin 117 may be arranged correspondingly to the slider 30, for example, one slider 30 corresponds to one fixing pin 117. When the opening area of ​​the limiting opening matches the object, the fixing pin 117 may be used to fix the slider 30 to clamp the object.

[0058] In one embodiment, the open ring includes a first open ring and a second open ring, the first open ring is fixedly connected to the second open ring, the first open ring and the second open ring are cocentric, and the radius of the first open ring is greater than the radius of the second open ring.

[0059] Please continue to refer to Figure 2As an example, the openings of the first open ring 115a and the second open ring 115b are adjacent to each other, forming the opening of the open ring 115. In other embodiments, the open ring may further include a third open ring, a fourth open ring, etc., and the present application does not specifically limit the number of the open rings.

[0060] In the above embodiment, by making the open ring 115 include a first open ring 115a and a second open ring 115b, and the first open ring 115a and the second open ring 115b are fixedly connected by a fixing member 115e, the stability of the fixing assembly can be enhanced, avoiding unstable fixation of the object due to only one open ring 115.

[0061] In one embodiment, the rack includes a first rack and a second rack; the first rack is located on the surface of the first open ring, and the first rack is movably connected to the first open ring; the second rack is located on the surface of the second open ring, and the second rack is movably connected to the second open ring.

[0062] Please continue to refer to Figure 2 , wherein, since the first rack 115c and the second rack 115d are respectively located on the surfaces of the first open ring 115a and the second open ring 115b, the first rack 115c can rotate around the surface of the first open ring 115a, and the second rack 115d can rotate around the surface of the second open ring 115b. As an example, the gear 40 can be meshed and connected with a rack, such as meshed and connected with the first rack 115c; the gear 40 can also be connected with multiple racks, such as meshed and connected with the first rack 115c and the second rack 115d respectively. In other embodiments, the racks can also include a third rack, a fourth rack, etc., and the present application does not specifically limit the number of racks.

[0063] In one embodiment, the surface of the slider in contact with the open ring includes a protruding limit piece; the surfaces of the first open ring and the second open ring in contact with the slider include limit grooves that engage with the limit piece; the limit grooves are used to limit the moving distance of the slider.

[0064] As an example, see Figure 2 , Figure 3a and Figure 3b The limiter 307 can be located on the side of the slider 30 parallel to the AOC surface, or on the bottom surface of the slider 30 parallel to the AOB surface. The limiter groove (not shown) is used to limit the movement of the slider 30 in the plane parallel to the XOY plane, so that the movement distance of the slider 30 in the direction parallel to the OC direction is zero.

[0065] As an example, the end of the slider 30 close to the center of the open ring also includes a contact piece 305, which is used to contact the object. The surface of the contact piece 305 may include a plurality of small holes to increase the roughness of the surface of the contact piece 305, so as to better fix the object.

[0066] Please refer to Figure 4 In one embodiment, the open ring includes a groove 115f for accommodating the fixing pin, and the inner surface of the groove 115f includes a thread (not shown); the fixing pin 117 includes: a support column 117a and a cap 117b, and the surface of the support column 117a includes a thread 117c arranged corresponding to the thread on the inner surface of the groove 115f; the cap 117b is fixedly connected to one end of the support column 117a, and the diameter of the cap 117b is larger than the opening size of the slide groove. When the fixing pin 117 moves to the lowermost end of its moving direction, the cap 117b contacts the slider.

[0067] As an example, the shape of the orthographic projection of the cap 117b along the OZ direction may include a circle, the diameter of the cap 117b is the diameter of the circle, and the opening size of the slide groove is the width of the slide groove in the OB direction.

[0068] As an example, by screwing the fixing pin 117, the fixing pin 117 can be screwed into the groove 115f of the open ring for accommodating the fixing pin 117, so that the fixing pin 117 is connected to the open ring, and the pressure of the slider by the cap 117b and the open ring is clamped to achieve the purpose of limiting the movement of the slider.

[0069] In the above embodiment, since the interior of the slider also includes a slide groove for limiting the moving direction and moving distance of the slider and penetrating the slider along the thickness direction of the slider, the fixing pin 117 is used to penetrate the slide groove and is connected to the open ring. The fixing pin 117 can slide in the slide groove, and the slider can be fixed by the pressure of the cap 117b of the fixing pin 117 and the open ring on the slider. Therefore, the opening area of ​​the limiting opening can be continuously adjusted to be suitable for objects of different sizes, and has a wide range of applications.

[0070] Please refer to Figure 5a-5c In one embodiment, the fixing assembly further comprises an open ring and a fixing pin; a rack is distributed on the surface of the open ring; the adjusting portion comprises at least two gears and at least two sliders; the side wall of the slider comprises a toothed structure; at least two gears are distributed on the inner side of the open ring at intervals, and are respectively meshed with the toothed structure of the slider and the rack on the inner side of the open ring; the fixing pin 117 comprises a support column 117a, a first cap 117d and a second cap 117e located at both ends of the support column 117a, and a The protrusion 117f and the support column 117a pass through the slider 30 and the open ring. The slider 30 also includes a plurality of slots 310 arranged at intervals along the moving direction of the slider 30. The slots 310 include a first sub-slot 311 and a second sub-slot 313. The first sub-slot 311 passes through the slider 30 along the thickness direction of the slider 30. The first sub-slot 30 is used to accommodate the support column 117a, and the second sub-slot 313 is used to accommodate the protrusion 117f, thereby fixing the slider 30. The moving direction of the slider 30 intersects with the open ring.

[0071] In the above embodiment, by placing the protrusion 117f of the fixing pin 117 in the second sub-slot 313 of the slider 30, the slider 30 can be limited to move in the OA direction, thereby clamping the object. By adjusting the slot 310 into which the fixing pin 117 is inserted, the opening area of ​​the limiting opening can be adjusted to be suitable for objects of different sizes.

[0072] Please refer to Figure 6a In one embodiment, the clamp also includes: a positioning device 50, which is connected to a fixed component of a jaw portion 11, and the center of the limiting opening of the positioning device 50 and the center of the limiting opening of the fixed component of the jaw portion 11 are located on a straight line, and the extension direction of the straight line is perpendicular to the plane where the limiting opening of the fixed component is located.

[0073] In the above embodiment, the position of the object can be first determined by the positioning device 50. Since the center of the limiting opening of the positioning device 50 and the center of the limiting opening of the fixing component of the jaw portion 11 are located on a straight line, and the extension direction of the straight line is perpendicular to the plane where the limiting opening of the fixing component is located, when the positioning device 50 fixes the object, the object can be accurately inserted into the limiting opening of the fixing component, thereby ensuring that the object can be accurately inserted into the limiting opening of the fixing component without sight, thereby improving the accuracy and simplicity of operation.

[0074] Please refer to Figure 6a and Figure 6b In one embodiment, the positioning device 50 includes: a positioning screw 51 and an annular structure 52, the annular structure 52 includes a first sub-annular segment 521 and a second sub-annular segment 522, the first sub-annular segment 521 is movably connected to the second sub-annular segment 522, when the first sub-annular segment 521 is closed, the first sub-annular segment 521 and the second sub-annular segment 522 form a closed circular ring, when the first sub-annular segment 521 is opened, the annular structure 52 forms an opening; the positioning screw 51 passes through the second sub-annular segment 522; wherein the contact surface between the second sub-annular segment 522 and the positioning screw 51 includes a thread corresponding to the thread of the positioning screw 51.

[0075] As an example, when the first sub-annular segment 521 and the second sub-annular segment 522 form a closed ring, the object is inserted into the limited opening of the positioning device 50, and the positioning screw 51 is screwed so that the positioning screw 51 and the annular structure 52 clamp the object. After the objects are docked, the docked objects need to be separated from the clamp, and the first sub-annular segment 521 can be opened.

[0076] As an example, the first sub-annular segment 521 and the second sub-annular segment 522 may be movably connected via a rotating shaft, and the first sub-annular segment 521 may rotate relative to the rotating shaft to be opened or closed.

[0077] Please refer to Figure 6c In one embodiment, the second sub-annular segment 522 includes a cavity for accommodating the first sub-annular segment 521 and a button groove 53 located on the outer wall of the second sub-annular segment 522; the annular structure also includes: a sliding button 54, located in the button groove 53 on the outer wall of the second sub-annular segment 522, the sliding button 54 is connected to the first sub-annular segment 521, and the sliding button 54 is used to drive the first sub-annular segment 521 to retract or extend into the second sub-annular segment 522.

[0078] In the above embodiment, the second sub-annular segment 522 includes an opening for accommodating the first sub-annular segment 521, and the sliding button 54 is connected to the first sub-annular segment 521. By toggling the sliding button 54, the first sub-annular segment 521 can be driven to retract into or extend out of the second sub-annular segment 522. On the one hand, the stability of the annular structure is improved, and on the other hand, the occupied space of the annular structure is reduced, thereby reducing the requirement for the operating space.

[0079] Please continue to refer to Figure 6a and Figure 6c In one embodiment, the clamp further includes: a first connecting member 61 and a second connecting member 62; the first connecting member 61 is rotatably connected to the second connecting member 62, the first connecting member 61 is connected to the fixing assembly, and the second connecting member 62 is connected to the positioning device 50.

[0080] As an example, a plane formed by the rotation direction of the first connecting member 61 or the second connecting member 62 is parallel to the YOZ plane.

[0081] In the above embodiment, by setting the first connecting member 61 and the second connecting member 62, the fixing assembly is connected to the positioning device 50 through the first connecting member 61 and the second connecting member 62, and the first connecting member 61 and the second connecting member 62 are rotatably connected through the rotating shaft 63, so that when the two relative jaw parts 11 are in contact, the fixing device 50 is not affected by the force of the objects docking, thereby avoiding the positioning device 50 from slipping due to the force on the positioning screw 51, thereby extending the service life of the clamp.

[0082] The above clamp has the following unexpected beneficial effects:

[0083] The clamp of the present application includes: a jaw portion for rotating with the clamp arm; at least one jaw portion includes a fixed component with a limit opening; the fixed component includes an adjustment portion, and the adjustment portion is used to adjust the opening area of ​​the limit opening and clamp the object passing through the limit opening. The present application sets the jaw portion that rotates with the clamp arm to include a fixed component with a limit opening, and clamps the object passing through the limit opening, such as a joint, through the limit opening of the fixed component. Each jaw portion clamps a joint, and then force is applied to the clamp arm to make two opposite jaw portions contact, so that the objects fixed by the jaw portions contact, thereby achieving the docking of the joints. In addition, the present application can adjust the opening area of ​​the limit opening through the adjustment portion, so that it is suitable for quick connectors of different sizes, which broadens the scope of application of the clamp.
