[0029] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] The connecting buckle in the first embodiment of the utility model refers to Figure 1 The workpiece includes a body 6 and a connecting portion 5, and the connecting portion 5 is fixedly connected to the body 6; Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The connection buckle comprises: a connection seat 1 and a blocking mechanism 3; the connection seat 1 is provided with a through hole 11 and a connection slot unit 2, the through hole 11 is for the body 6 to pass through; the connection slot unit 2 comprises a first groove 21 and a second groove 22; the first groove 21 is provided on the connection seat 1, the opening of the first groove 21 faces the axial direction of the through hole 11, and the connection part 5 enters the first groove 21; when the body 6 enters the through hole 11 along the axial direction of the through hole 11, the connection part 5 on the body 6 will enter the first groove 21 from the opening of the first groove 21. The second groove 22 is provided on the connection seat 1, the opening of the second groove 22 is communicated with the first groove 21, and the connection part 5 after entering the first groove 21 enters the second groove 22 along the circumferential direction of the through hole 11; after the connection part 5 enters the first groove 21, the connection part 5 is driven to move by rotating the body 6, so that the connection part 5 enters the second groove 22. At this time, the first groove 21 and the second groove 22 are arranged along the circumferential direction of the through hole 11, which can greatly reduce the volume of the connection buckle. The second groove 22 can be set at multiple positions relative to the first groove 21, so that the volume of the connecting buckle can be reduced, and the blocking mechanism 3 blocks the connecting part 5 from entering the first groove 21 from the second groove 22. The blocking mechanism 3 in this state can be set in the first groove 21, further reducing the volume of the connecting buckle. At the same time, the force along the axial direction of the through hole 11 applied to the body 6 will be applied to the side wall of the second groove 22, so that the fixing of the connecting buckle to the body 6 can be made more secure. The blocking mechanism 3 is set on the connecting seat 1 and can be switched between the first state and the second state; when the blocking mechanism 3 is in the first state, the blocking mechanism 3 blocks the connecting part 5 from entering the first groove 21 from the second groove 22; when the blocking mechanism 3 is in the second state, the connecting part 5 can enter and exit from the opening of the second groove 22, and the connecting part 5 can enter and exit from the opening of the first groove 21. That is, the blocking mechanism 3 blocks the end of the connecting part 5 from the second groove 22 for connecting to the first groove 21, so that the connecting part 5 cannot move from the second groove 22 to the first groove 21, that is, the rotation of the body 6 is prevented. The force on the body 6 in the direction of rotation is small, so a small force is needed to firmly connect the workpiece. Further, the body 6 is a cylinder, and the through hole 11 is a cylindrical through hole 11 that matches the body 6. The inner wall surface of the through hole 11 matches the outer side surface of the body 6, so that the connection buckle is more tightly connected to the workpiece.

[0032] Reference Figure 6The blocking mechanism 3 includes a block 23 and a torsion spring 32. The block 23 is rotatably arranged on the connecting seat 1 and switches between a first position and a second position. When the blocking mechanism 3 is in the first state, the block 23 is in the first position and blocks the connecting portion 5 from entering the first groove 21 from the second groove 22. When the blocking mechanism 3 is in the second state, the block 23 is in the second position. One end of the torsion spring 32 is fixedly connected to the connecting seat 1, and the other end of the torsion spring 32 is fixedly connected to the block 23, and drives the block 23 to switch from the second position to the first position. At the same time, the torsion spring 32 also has the function of keeping the block 23 in the first position. When the connecting portion 5 enters the first groove 21 and when the connecting portion 5 enters the second groove 22, the blocking mechanism 3 is in the second state, and the block 23 is in the second position. At this time, the block 23 will not block the movement of the connecting portion 5, and the connecting portion 5 can freely enter and exit the first groove 21 and the second groove 22. After the connecting portion 5 enters the second groove 22, the torsion spring 32 drives the block 23 to move to the first position, i.e., the first state of the blocking mechanism 3, at which the block 23 blocks the exit of the connecting portion 5 from the second groove 22 to the first groove 21, so that the connecting portion 5 is blocked in the second groove 22. Specifically, the block 23 can be set as a cam, and when the torsion spring 32 drives the block 23 to switch to the first position, the raised portion of the cam rotates into the first groove 21 and blocks the opening of the second groove 22. By blocking the opening of the second groove 22 in the first groove 21, space is greatly saved and the volume of the connecting buckle is reduced. When the cam moves to the second position, the raised portion of the cam rotates and moves outside the first groove, so that the connecting portion 5 can enter and exit the first groove 21 and the second groove 22.

[0033] The blocking mechanism 3 further includes a lever 33, which is fixedly connected to the block 23 and is used to drive the block 23 to switch from the first position to the second position. Specifically, one end of the lever 33 is fixedly connected to the block 23, and the other end of the lever 33 extends to the outside of the connection seat 1. By driving the lever 33 exposed to the outside of the connection seat 1 to drive the block 23 to rotate, the block 23 can be driven to switch from the first position to the second position or to move from the second position to the first position. Since the block 23 is driven by the torsion spring 32 when switching from the second position to the first position, the lever 33 is mainly used to drive the block 23 to resist the driving force of the torsion spring 32 and switch to the second position.

[0034] Reference Figure 6 and Figure 8The blocking mechanism 3 further includes a positioning groove 34, a positioning pin 35 and a first spring 36. The positioning groove 34 is arranged on the block 23, the positioning pin 35 is slidably arranged on the connecting seat 1, one end of the first spring 36 is fixedly connected to the connecting seat 1, and the other end of the first spring 36 is fixedly connected to the positioning pin 35; when the block 23 is located at the second position, the first spring 36 drives the positioning pin 35 to enter the positioning groove 34 and prevents the block 23 from switching to the first position. When the block 23 is driven to switch to the second position, if there is no external force to fix it, the torsion spring 32 will drive the block 23 to the first position again. Therefore, if the block 23 stays in the second position, it is necessary to use an external force to fix the block 23 to resist the driving force of the torsion spring 32, which is very inconvenient. With the positioning pin 35 and the first spring 36, when the block 23 moves to the second position, the first spring 36 pops out the positioning pin 35 and cooperates with the positioning groove 34 on the block 23 to prevent the block 23 from moving, so that the block 23 stays in the second position. After the connecting portion 5 is placed into the second groove 22 , the positioning pin 35 is moved out of the positioning slot 34 , and the torsion spring 32 drives the stopper 23 to switch to the first position and block the stopper 23 in the second groove 22 .

[0035] Reference Figure 5 and Figure 6 The connecting buckle further includes a pressing mechanism 4, which is disposed in the second groove 22 and is used to press the connecting portion 5 in the second groove 22 against the wall surface of the second groove 22. After the connecting portion 5 enters the second groove 22, there may be a gap between the connecting portion 5 and the second groove 22, and this gap may cause the connecting portion 5 to shake in the second groove 22, which may cause damage to the workpiece. Therefore, the pressing mechanism is used to press the connecting portion 5 entering the second groove 22, so that the workpiece is more firmly connected by the connecting buckle.

[0036] The pressing mechanism 4 includes a pressing block 41 and a second spring 42, the pressing block 41 is slidably connected to the connecting seat 1, and the second spring 42 is used to drive the pressing block 41 to enter the second groove 22 and press the connecting portion 5 in the second groove 22 against the wall surface of the second groove 22. Using the second spring 42 and the pressing block 41 to press the connecting portion 5 can not only make the connection of the connecting portion 5 more secure, but also absorb part of the impact force on the workpiece through the spring, thereby protecting the workpiece.

[0037] One end of the pressing block 41 that abuts against the connecting portion 5 is a convex arc surface, and the connecting portion 5 is provided with a concave arc surface adapted to the arc surface. When the pressing block 41 squeezes the connecting portion 5 in the second groove 22 onto the wall surface of the second groove 22, the convex arc surface fits with the concave arc surface. The cooperation between the convex arc surface and the concave arc surface can not only firmly press the connecting portion 5 onto the side wall of the second groove 22, but also play a role in positioning the connecting portion 5, so that the positioning of the connecting portion 5 in the second groove 22 is more accurate. At the same time, when the connecting portion 5 moves out of the second groove 22, extrusion will occur between the convex arc surface and the concave arc surface, so that the second spring 42 is compressed. Therefore, the cooperation between the convex arc surface and the concave arc surface can not only position the connecting portion 5, but also will not affect the stopper 23 from entering and exiting the second groove 22. To prevent the pressing block 41 from extending too long in the second groove 22 and thereby blocking the connecting portion 5 from entering the second groove 22, a limit block can be provided to limit the length of the pressing block 41 entering the second groove 22, thereby ensuring that the connecting portion 5 can smoothly enter the second groove.

[0038] Reference Figure 3 and Figure 6 , the connecting buckle includes at least one blocking device, and a plurality of connecting groove 2 units are provided on the connecting seat 1, and the connecting groove units 2 are arranged along the circumference of the through hole 11. In order to make the connection buckle fix the workpiece more firmly, a plurality of connecting parts 5 can be provided on the main body 6, and the connecting parts 5 correspond to the connecting groove units 2 one by one. Among the plurality of connecting groove units 2, only one of the connecting groove units 2 needs to be provided with a blocking mechanism 3, and the other connecting groove units 2 do not need to be provided with a blocking mechanism 3. Only one blocking mechanism 3 is needed to prevent one of the connecting parts 5 from leaving the second groove 22, and the other connecting parts 5 cannot leave the second groove 22 corresponding thereto. The provided connecting groove units 2 fix the workpiece at multiple points, improve the force structure of the connecting buckle, and make the connection of the connecting buckle to the workpiece more stable.

[0039] The connecting buckle also includes a plurality of extrusion mechanisms 4, which correspond one-to-one to the connecting groove units 2 and are used to squeeze the connecting portion 5 in the second groove 22 onto the wall surface of the second groove 22, thereby improving the connecting effect of the connecting buckle on the workpiece.

[0041] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
