[0052] Place the battery 2 inside the battery box 1, rotate the turntable 37, and the turntable 37 drives the threaded rod 36 to rotate. Since the threaded rod 36 is threadedly connected to the connecting plate 35, the connecting plate 35 moves inward with the rotation of the threaded rod 36, and the connecting plate 35 drives the two connecting rods 34 to move inward. The connecting rod 34 drives the clamping plate 32 and the second rubber pad 33 to clamp and fix the outer side of the four corners of the battery 2. Place the battery 2 and the battery box 1 inside the battery pack placement cavity of the fuel engine, and then fix the battery box 1.

[0053] When the mechanical device is idle, the handle 21 is pulled upward, the handle 21 drives the movable plate 18 to move upward, the movable plate 18 drives the protective baffle 15 and the first limit plate 16 to move upward and stretch the first spring 20, when the protective baffle 15 leaves one side of the charging head 11, the first limit plate 16 will leave the inside of the limit groove 17, the charging head 11 is pulled outward, the charging head 11 drives the charging cable 10 to move outward, the charging cable 10 drives the winding rod 9 and the insulating rotating rod 7 to rotate, the insulating rotating rod 7 drives the conductive slip ring 6 to rotate, so that the charging head 11 can be pulled to the outside of the mechanical device.

After the charging work is completed, the charging head 11 is inserted back to its original position. At this time, the insulating rotating rod 7 will return to its original position under the torsion force of the torsion spring 12, and the insulating rotating rod 7 drives the winding rod 9 to reel the charging cable 10. The handle 21 is released, and the movable plate 18 drives the protective baffle 15 and the first limiting plate 16 to return to their original positions under the elastic force of the first spring 20. The protective baffle 15 will provide dust protection for the plug-in part of the charging head 11, and the first limiting plate 16 will limit and fix the charging head 11.

[0054] The present invention connects the conductive slip ring 6, the charging line 10 and the charging head 11 to the battery 2 and the conductive rod 5, so that the charging head 11 can be pulled out when the mechanical equipment is idle, and then the battery 2 is charged, thereby avoiding the situation that the battery 2 and the battery box 1 need to be disassembled and taken out for charging when the mechanical equipment is idle, making the charging process of the battery 2 relatively simple and convenient, reducing the workload during the charging process of the battery 2, and making the use effect of the battery pack better. This embodiment specifically solves the problem that when the fuel engine starting battery pack in the prior art is actually used, the power output end of the battery pack is connected to the electric ignition structure on the fuel engine, and the charging end of the battery pack is connected to the power generation device on the fuel engine. The fuel engine can charge the battery pack when it is working, but some mechanical equipment may be idle for a long time, so that the battery pack may be insufficient in power, thereby affecting the starting of the fuel engine. At this time, the battery pack needs to be disassembled from the mechanical equipment for charging. This battery connection and charging method is relatively troublesome, and the workload of charging the battery pack is large, so that the use effect of the battery pack is not good enough.

[0055] The present invention provides Figure 2 , Figure 3 , Figure 8 and Fig.12 In the fuel engine starting battery pack shown, a connector 22 is plugged into the discharge plug 4, and a limit fixing assembly is arranged outside the connector 22;

[0056] The limiting and fixing assembly includes two movable blocks 23 arranged on one side of the battery box 1, the two movable blocks 23 are respectively arranged on the front and rear sides of the discharge plug 4, a second limiting plate 24 is fixedly arranged on the inner side of the movable block 23, and the two second limiting plates 24 are respectively arranged on the outer sides of the front and rear ends of the connecting head 22, two fixed blocks 25 are fixedly arranged on one side of the battery box 1, the two fixed blocks 25 are respectively arranged on the outer sides of the two movable blocks 23, a bidirectional threaded rod 26 is rotatably connected between the two fixed blocks 25, one end of the bidirectional threaded rod 26 passes through the bottom ends of the two movable blocks 23 and a fixed block 25 and extends to the outer side of the fixed block 25, the bidirectional threaded rod 26 is threadedly connected to the two movable blocks 23 and the thread directions are opposite, and a rotating block 27 is fixedly arranged at one end of the bidirectional threaded rod 26.

A first slider 29 is arranged inside the first slide groove 28 . The outer sides of the two first sliders 29 are respectively fixedly connected to the two movable blocks 23 .

[0058] In the process of inserting the connector 22 into the discharge plug 4, the rotating block 27 is first rotated, and the rotating block 27 drives the bidirectional threaded rod 26 to rotate. Since the bidirectional threaded rod 26 is connected to the two movable blocks 23 by threads, the two movable blocks 23 move away from each other as the bidirectional threaded rod 26 rotates, and the two movable blocks 23 drive the two second limit plates 24 to move away from each other. At this time, the end of the connector 22 is inserted into the discharge plug 4, and then the rotating block 27 is rotated in the opposite direction. The rotating block 27 drives the bidirectional threaded rod 26 to rotate in the opposite direction. At this time, the two movable blocks 23 move away from each other as the bidirectional threaded rod 26 rotates. The reverse rotation of the threaded rod 26 brings the two movable blocks 23 closer to each other, and the two second limiting plates 24 move to the outside of the front and rear ends of the connecting head 22, so that the two second limiting plates 24 limit and fix the connecting head 22. The present invention limits and fixes the connection between the connecting head 22 and the discharge plug 4 by the two second limiting plates 24, so that the connection between the connecting head 22 and the discharge plug 4 is more stable, and the connection between the connecting head 22 and the discharge plug 4 is prevented from loosening when the fuel engine is working, and the practicality is strong.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
