In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0024] Example 1

[0025] like Figure 1-5 As shown, it is the first embodiment of the utility model, which provides a cavity seat of a wire circulator, including a base 1, a cavity body 2 is arranged on the top of the base 1, and a limiting ring 3 is fixedly connected to the four sides of the top of the base 1, and the surface of the cavity body 2 contacts the surface of the limiting ring 3, and the front and rear ends of the top of the base 1 are provided with mounting grooves 4, and the front and rear ends of the bottom of the cavity body 2 are fixedly connected with mounting blocks 5, and the bottom of the mounting block 5 extends to the inner cavity of the mounting groove 4 and is detachably connected to the inner cavity of the mounting groove 4, and the inner cavity of the base 1 is provided with a positioning mechanism 6;

[0026] The positioning mechanism 6 includes a receiving groove 601, which is opened at the front end and the rear end of the inner cavity of the base 1. The inner cavity of the receiving groove 601 is slidably connected with a fixing block 602. The sides of the two fixing blocks 602 that are close to each other are fixedly connected with a clamping column 603. The sides of the two mounting blocks 5 that are away from each other are each provided with a clamping groove 604. One end of the clamping column 603 extends to the inner cavity of the clamping groove 604 and is clamped with the inner cavity of the clamping groove 604.

[0027] like Figure 1-5 As shown, the base 1 is used to install the cavity body 2, and the limiting ring 3 can limit the cavity body 2 to prevent the cavity body 2 from shifting at the top of the base 1, while ensuring that the mounting block 5 can be smoothly inserted into the interior of the mounting groove 4. By inserting the mounting block 5 into the interior of the mounting groove 4, a certain positioning effect can be achieved on the cavity body 2, further preventing the cavity body 2 from shifting at the top of the base 1. The positioning mechanism 6 can be used to fix the mounting block 5 inside the mounting groove 4, thereby improving the stability of the mounting block 5 inside the mounting groove 4, ensuring that the cavity body 2 will not fall off from the top of the base 1. At the same time, the positioning mechanism 6 can also be used to cancel the fixing effect of the mounting block 5, so that the cavity body 2 can be disassembled, maintained or replaced.

[0028] Example 2

[0029] Reference Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0030] In this embodiment, the inner cavity of the base 1 is movably connected to a threaded column 605 through a bearing, the threads on both sides of the surface of the threaded column 605 are set in opposite directions, and both sides of the surface of the threaded column 605 are threadedly connected to a threaded sleeve 606, and the bottom of the fixed block 602 is fixedly connected to the top of the threaded sleeve 606.

[0031] The front end of the threaded column 605 penetrates to the outside of the base 1 and is fixedly connected to a rotating block 607 .

[0032] like Figure 4 As shown, by rotating the rotating block 607, the threaded column 605 can be driven to rotate. Since the threads on both sides of the surface of the threaded column 605 are set in opposite directions, when the threaded column 605 rotates, the two threaded sleeves 606 can be driven to move synchronously and in opposite directions on the surface of the threaded column 605, so that the two mounting blocks 5 can be fixed at the same time.

[0033] Example 3

[0034] Reference Figure 2-5 , which is the third embodiment of the utility model, and this embodiment is based on the previous two embodiments.

[0035] In this embodiment, positioning grooves 7 are provided on both sides of the top of the base 1, and positioning columns 8 are fixedly connected to both sides of the bottom of the cavity body 2. The bottom of the positioning column 8 extends to the inner cavity of the positioning groove 7 and engages with the inner cavity of the positioning groove 7.

[0036] A limiting groove 9 is provided at the bottom of the inner cavity of the base 1 , and a limiting block 10 is fixedly connected to the bottom of the threaded sleeve 606 . The bottom of the limiting block 10 extends to the inner cavity of the limiting groove 9 and is slidably connected to the inner cavity of the limiting groove 9 .

[0037] The inner cavity of the limiting block 10 is slidably connected to the limiting column 11 , and both ends of the limiting column 11 are fixedly connected to the inner wall of the limiting groove 9 .

[0038] like Figure 2-5 As shown, the positioning groove 7 and the positioning column 8 cooperate to assist in positioning the cavity body 2, and the limiting groove 9, the limiting block 10 and the limiting column 11 cooperate to limit the threaded sleeve 606 to prevent the angle of the threaded sleeve 606 from being offset.

[0039] When in use, first place the cavity body 2 on the top of the base 1, and insert the mounting block 5 into the interior of the mounting groove 4, and the positioning column 8 into the interior of the positioning groove 7, and then rotate the rotating block 607. The rotating block 607 can drive the threaded column 605 to rotate. Since the threads on both sides of the surface of the threaded column 605 are set in opposite directions, when the threaded column 605 rotates, it can drive the two threaded sleeves 606 to move synchronously and oppositely on the surface of the threaded column 605. The threaded sleeve 606 can drive the fixed block 602 and the clamping column 603 to move. After the clamping column 603 is inserted into the interior of the clamping groove 604, the mounting block 5 can be fixed inside the mounting groove 4, thereby positioning the cavity body 2. When the cavity body 2 needs to be disassembled and maintained, the rotating block 607 can be rotated in the opposite direction.

The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the prior art. The machinery, parts and equipment all adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented through simple programming by technicians in this field, which is common knowledge in the field. This application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.
