[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-3 , a special disassembly tool for bolts, which includes a cylinder body 1. A heater 2 is installed outside the cylinder body 1. A bolt body 3 is arranged inside the cylinder body 1. A support nut 4 is arranged at the top of the cylinder body 1. A disassembly mechanism 5 is arranged inside the cylinder body 1;

[0021] The disassembly mechanism 5 includes a turntable 501, a handle 502, a dual-axis motor 503, a threaded rod 504, a sliding sleeve 505, an extension rod 506 and a claw flap 507. A turntable 501 is arranged inside the cylinder body 1. A handle 502 is fixedly installed at the bottom of the turntable 501. A dual-axis motor 503 is installed inside the turntable 501. A threaded rod 504 is arranged inside the turntable 501. A sliding sleeve 505 is arranged outside the threaded rod 504. An extension rod 506 is installed inside the turntable 501. A claw flap 507 is arranged outside the bolt body 3.

[0022] In Figure 1 and Figure 2 , the support nut 4 and the bolt body 3 are threadedly connected. The turntable 501 is located below the bolt body 3. By setting the bolt body 3 and the support nut 4, the connection between the cylinder body 1 and the heater 2 is stabilized.

[0023] In Figure 1 and Figure 2 , by setting the disassembly mechanism 5, the structures of the disassembly mechanism 5 cooperate with each other, and the purpose of facilitating the rapid disassembly of the bolt body 3 can be achieved. The disassembly mechanism 5 includes a turntable 501, a handle 502, a dual-axis motor 503, a threaded rod 504, a sliding sleeve 505, an extension rod 506 and a claw flap 507. The handle 502 extends to the outside of the cylinder body 1. The number of the threaded rods 504 is two. The left and right output shafts of the dual-axis motor 503 are respectively connected to the two threaded rods 504.

[0024] In Figure 2 and Figure 3 , one sides of the two threaded rods 504 coated with the dual-axis motor 503 are respectively connected to the left and right inner walls of the turntable 501. By setting the dual-axis motor 503, when the controller drives the dual-axis motor 503 to start, it can drive the threaded rod 504 to rotate, so that the two sliding sleeves 505 and the extension rod 506 and the claw flap 507 at the top move in opposite or opposite directions, facilitating the claw flap 507 to fix the bottom of the bolt body 3 of different models.

[0025] In Figure 2 and Figure 3 , the two sliding sleeves 505 are respectively sleeved outside the two threaded rods 504. One sides of the two extension rods 506 far from the two extension rods 506 both extend to the outside of the turntable 501.

[0026] In Figure 2 andFigure 3 In it, the tops of the two extension rods 506 are respectively connected to the bottoms of the two claw petals 507, and the two claw petals 507 are respectively engaged with the left and right sides of the bolt body 3, thus solving the problem that in the process of disassembling the existing bolt body 3, it is usually necessary to remove the heater 2 first, then disassemble the cylinder body 1, and finally remove the bolt body 3. The process is complex, time-consuming and inefficient, which is not conducive to the maintenance of the equipment.

[0027] To sum up, for this special bolt disassembly tool, by setting the turntable 501, when disassembling the bolt body 3, the user needs to hold the handle 502 and place the turntable 501 directly below the bolt body 3. By setting the double-shaft motor 503, the controller drives the double-shaft motor 503 to start, which can drive the threaded rod 504 to rotate, so that the two sliding sleeves 505 and the extension rods 506 and claw petals 507 at the top move in opposite or away directions, facilitating the claw petals 507 to fix the bottom of the bolt body 3 of different models.

[0028] Moreover, when disassembling the bolt body 3, first the user holds the handle 502 and places the turntable 501 directly below the bolt body 3, then the controller drives the double-shaft motor 503 to start, making the two threaded rods 504 rotate, driving the two sliding sleeves 505 and the claw petals 507 at the top to move in opposite directions, then making the two claw petals 507 firmly fix the bolt body 3, and finally rotating the handle 502 clockwise or counterclockwise, driving the bolt body 3 to rotate synchronously, so that the bolt body 3 and the support nut 4 can be separated, solving the problem that in the process of disassembling the existing bolt body 3, it is usually necessary to remove the heater 2 first, then disassemble the cylinder body 1, and finally remove the bolt body 3. The process is complex, time-consuming and inefficient, which is not conducive to the maintenance of the equipment.
