[0026] Referring to Figure 5 As shown in the embodiment: one side of the second clamp block 3 is provided with a heat preservation pad 18, when the user closes the first clamp block 2 and the second clamp block 3, the heat preservation pad 18 will block the gap between the first clamp block 2 and the second clamp block 3 after being closed, reducing the temperature loss inside the first clamp block 2 and the second clamp block 3 after being closed, and ensuring the stability of the holding temperature of the equipment.

[0027] The working principle of the utility model:

[0028] Step one, the user expands the first bolt 6 through the rotating shaft, then uses the first handle 4 to expand the first clamp block 2 and the second clamp block 3 through the rotating shaft at both ends of the first charging connecting frame 1, so as to clamp the oil field wellhead body 7, after clamping the oil field wellhead body 7, the first clamp block 2 and the second clamp block 3 are closed, and the first bolt 6 is rotated to make one end of the bolt inserted into the pin slot of the first limiting block 5, so as to fix the closed state of the first clamp block 2 and the second clamp block 3, the user connects the power supply through the power supply hole at the back of the first charging connecting frame 1, and adjusts the temperature of the first electromagnetic heating plate 19 through the control panel at the top of the first clamp block 2, so as to heat the crude oil flowing in the oil field wellhead body 7, and the design of the first bolt 6 allows the user to quickly disassemble the equipment, and the thick crude oil in the oil field wellhead body 7 is heated by the first electromagnetic heating plate 19.

[0029] Step two, the user first inserts the first bolt 6 into the inner wall of the first limiting block 5, moves the first limiting buckle 9 along the first sliding groove 8 to the specified position, and limits the first bolt 6, thereby enhancing the stability of the insertion of the first bolt 6 and the first limiting block 5. In the process of moving the first limiting buckle 9, it moves along the surface of the first limiting rod 11 through the inner wall of the first circular groove 10, and the first limiting buckle 9 extrudes the first spring 12 when moving, so that it is stored and compressed, when the first limiting buckle 9 needs to return to the original position, the first spring 12 releases and rebounds after being released, and automatically pushes the first limiting buckle 9 back to the original position, and the automatic reset function is realized through the second sliding groove 13.

[0030] Step three, the user operates the first clamp block 2 and the second clamp block 3 to close, the outer wall of the oil field wellhead body 7 extrudes the first top plate 15, and then compresses the second spring 14 in the second sliding groove 13, so that it is stored and extruded. The extrusion action causes the first top plate 15 at both ends to form a clamping limit on the oil field wellhead body 7, so as to prevent the first clamp block 2 and the second clamp block 3 from being deviated due to external collision or shaking of the oil field wellhead body 7. When the user expands the first clamp block 2 and the second clamp block 3, the oil field wellhead body 7 no longer extrudes the first top plate 15, the second spring 14 releases and rebounds immediately, and pushes the first top plate 15 to move forward. The first top plate 15 moves in the inner wall of the first limiting groove 16 through the second limiting block 17 at the back of both ends, so as to ensure that the first top plate 15 will not come out of the inside of the second sliding groove 13.

[0031] Step four, the user operates to make the first clamp block 2 and the second clamp block 3 close, and the heat preservation pad 18 automatically blocks the gap after being closed, effectively reducing the internal temperature loss after the first clamp block 2 and the second clamp block 3 are closed, thereby ensuring the stability of the equipment in maintaining the temperature and ensuring the heating efficiency and the heat preservation effect.
