[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0028] like Figure 2 As shown, the first connecting component 1 has a first connecting shaft 11, and the first connecting shaft 11 is radially extended with a first connecting disk 12. Figure 3 and Figure 4 As shown, the end surface of the first connecting plate 12 facing away from the first connecting shaft 11 is provided with a plurality of spaced positioning blind holes 121, a positioning sleeve 122 is provided in the positioning blind hole 121, a locking screw 124 is axially provided on the first connecting plate 12, the locking screw 124 is threadedly connected to the positioning sleeve 122, and a positioning hole 123 is provided at one end of the positioning sleeve 122 facing away from the locking screw 124.

[0029] like Figure 5 As shown, the second connecting member 2 has a second connecting shaft 21, and a second connecting disk 22 is radially extended from the second connecting shaft 21. Figure 6 As shown, the end surface of the second connecting plate 22 facing away from the second connecting shaft 21 is provided with a plurality of positioning pins 23, and the arrangement of the positioning pins 23 is the same as that of the positioning blind holes 121, and the positioning pins 23 are adapted to the positioning holes 123. It should be noted that the number of the positioning pins 23 is the same as that of the positioning blind holes 121 and the arrangement is the same, and the top shape of the positioning pins 23 is adapted to the shape of the positioning holes 123, so that the top of the positioning pins 23 can be embedded in the positioning holes 123, as shown in FIG. Figure 1As shown, the positioning pin 23 can be a ball stud, and the positioning hole 123 is a tapered hole that matches the ball stud, wherein matching means that the maximum diameter of the tapered hole needs to be larger than the maximum diameter of the ball stud. When the locking screw 124 is tightened, the locking screw 124 abuts against the positioning pin 23.

[0030] The locking screw sleeve 3 is threadedly connected to the outer ends of the first connecting plate 12 and the second connecting plate 22 respectively, and the locking screw sleeve 3 locks and fixes the first connecting plate 12 and the second connecting plate 22. When the end faces of the first connecting plate 12 and the second connecting plate 22 are in contact and positioned with each other, the locking screw sleeve 3 is sleeved on the outer ends of the first connecting plate 12 and the second connecting plate 22 and fixed by threads to achieve locking and fixation of the first connecting plate 12 and the second connecting plate 22.

[0031] In an embodiment of the present invention, since the positioning blind holes 121 are arranged at intervals, they can be arranged at equal intervals or at unequal intervals.

[0032] When the positioning blind holes 121 are arranged at unequal intervals, Figure 3 As shown, the number of the positioning blind holes 121 is three, and the three positioning blind holes 121 are arranged in an isosceles triangle, or in an irregular triangle. It should be noted that the number of the positioning blind holes 121 can be designed according to the actual situation, and this embodiment is only described by taking the accompanying drawings as an example. Due to the unequal spacing arrangement. The positioning sleeves 122 in the three positioning blind holes 121 cooperate with the positioning pins 23 to achieve both positioning and limiting. The utility model can quickly locate the contact position, and the repeated assembly accuracy is higher and more stable.

[0033] When the positioning blind holes 121 are arranged at equal intervals, in order to ensure the consistency of the orientation of repeated assembly, a positioning screw needs to be axially arranged on the first connecting plate 12, and a blind hole matching the positioning screw is correspondingly arranged on the end face of the second connecting plate 22, and the positioning screw is abutted against the blind hole. The above-mentioned positioning screw and positioning blind hole are not shown in the accompanying drawings.

[0034] In one embodiment of the utility model, a threaded blind hole 24 is provided on the end face of the second connecting plate 22 facing away from the second connecting shaft 21, and the positioning pin 23 is threadedly connected in the threaded blind hole 24. The positioning pin 23 is connected to the second connecting plate 22 by threads, so that the positioning pin 23 can be replaced when a problem occurs.

[0035] In one embodiment of the present invention, the outer peripheral end of the first connecting disk 12 is provided with an annular outer arc surface 125 and an anti-falling thread 126 located beside the annular outer arc surface 125, and the outer peripheral end of the second connecting disk 22 is provided with a locking thread 221;

[0036] The inner hole of the locking screw sleeve 3 has a first connecting section 33, a second connecting section 32 and a third connecting section 31 which are coaxially arranged in sequence. The third connecting section 31 is provided with an internal thread 311 which cooperates with the locking thread 221. The first connecting plate 12 is arranged in the second connecting section 32. An annular inner arc surface 34 which abuts against the annular outer arc surface 125 is formed at the transition point between the second connecting section 32 and the first connecting section 33. The annular outer arc surface 125 can slide along the annular inner arc surface 34.

[0037] In one embodiment of the present invention, the radius of the annular outer arc surface 125 is equal to the radius of the annular inner arc surface 34. Figure 4 and Figure 7 As shown, Figure 4 The radius of the outer arc surface of the middle ring is 125, and the value of SR1 is Figure 7 The radius value SR2 of the annular inner arc surface 34 is consistent, so that the ball can move in an arc direction along the center of the ball.

[0038] In one embodiment of the present invention, the diameter of the second connecting section 32 is larger than the outer diameter of the first connecting disk 12 , and the diameter of the third connecting section 31 is smaller than the outer diameter of the second connecting disk 22 .

[0039] In one embodiment of the present invention, the locking thread 221 and the internal thread 311 are both multi-start threads. The multi-start threads can be used to quickly lock the device, and the number of rotations is determined by the lead of the multi-start threads. The larger the lead, the smaller the number of rotations required for locking.

[0040] In one embodiment of the present invention, the first connecting component is in the shape of a hollow shaft and has a first central through hole, and the second connecting component is in the shape of a hollow shaft and has a second central through hole.

[0041] When using the utility model, it is necessary to first loosen the locking screws 124 of the three positioning sleeves 122 on the first connection disk 12, and then align the first connection disk 12 with the second connection disk 22. After the alignment is completed, the locking screw sleeve 3 is used to tighten the first connection disk 12 and the second connection disk 22 through threads, so that the three positioning sleeves 122 of the first connection disk 12 and the three positioning pins 23 of the second connection disk 22 fit perfectly, and then tighten the locking screws 124 of the three positioning sleeves 122. During the locking process of the locking screw sleeve 3, the positioning pins 23 and the positioning sleeve 122 play a role in positioning and limiting, thereby improving the stability and positioning accuracy of repeated assembly.

[0042] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
