[0027] Specifically, during the operation, first hold the rear handle 1 firmly and accurately insert the extension rod 9 into the internal hole of the lock head 6; then, align the positioning hole on the extension rod 9 with the penetration position of the limit bolt 7 to ensure that the positioning hole and the hole position of the limit bolt are completely aligned; at this time, by rotating the limit bolt 7, it is possible to gradually penetrate the positioning holes of the lock head 6 and the extension rod 9, so that the extension rod 9 can be initially fixed, thereby preventing it from sliding or falling off during use; in order to further enhance the stability of the extension rod 9, by rotating the T-shaped locking bolt 8, it is possible to apply sufficient pressure to ensure that the lock head 6 and the extension rod are in a stable state. The rods 9 fit tightly together; the rotation operation of the T-locking bolt 8 can effectively make the lock head 6 fit tightly against the outer wall of the extension rod 9, increasing the tightness and firmness of the connection and avoiding looseness or instability during use; through this double fixing method, not only the stable connection between the extension rod 9 and the lock head 6 is guaranteed, but also the safety and reliability of the equipment in actual operation are further improved; this design takes into account various situations that the user may encounter during use. For example, when it is necessary to adjust the length of the extension rod or replace different accessories, a firm connection and quick adjustment can be achieved through simple operation.

[0028] Reference Figure 5 , Figure 6 and Figure 7A sprocket box 12 is installed on one side of the extension rod 9, and a sealing cover 13 is rotatably connected to one side of the outer wall of the sprocket box 12, and a shoulder strap hanging ring 22 is fixedly connected to the outer wall of the insulating transmission rod 15 and the extension rod 9; a positioning bolt 14 is threadedly connected to the inside of the sprocket box 12, and a guide plate 15 is slidably connected to the inside of the sprocket box 12; a sprocket disk 16 is rotatably connected to the inside of the guide plate 15, and two sprocket disks 16 are symmetrically arranged on the left and right; a guide groove 17 is opened through the inside of the guide plate 15, and the positioning bolt 14 is slidably connected to the guide groove 17; a chain tensioning adjuster 18 is installed inside the sprocket box 12, and the chain tensioning adjuster 18 is arranged on the adjacent side of the guide plate 15; a battery box 19 is fixedly connected to the other side of the outer wall of the rear handle 1, and a battery slot 20 is opened inside the battery box 19; a battery pack 21 is slidably connected to the inside of the battery box 19, and the battery pack 21 is slidably connected to the inner wall of the battery slot 20;

[0029] Specifically, first, carefully slide the guide plate 15 into the interior of the sprocket box 12. This step requires ensuring that the direction and angle of the guide plate are completely matched with the structure inside the sprocket box; then, adjust the position of the guide plate 15 so that it is on the same horizontal line as the sprocket disk 16 inside the sprocket box 12, thereby ensuring the precise alignment of the guide plate and the sprocket disk; this step is crucial for the smooth operation of the subsequent installation of the saw chain, and it is necessary to ensure that the horizontal alignment between the two is in the best state; then, use bolts to fix the guide plate 15 inside the guide groove 17; by tightening the bolts, the guide plate can be effectively fixed in the guide groove, thereby preventing the guide plate from loosening or shifting during operation; this stable installation method can ensure that the guide plate can provide stable support and guiding when it is subjected to the tension of the saw chain; after the guide plate is installed, wrap the saw chain around the outer walls of the two sprocket disks 16; then, by adjusting the chain tensioner 18. Perform precise tension adjustment; this process requires gradual adjustment to ensure that the tension of the saw chain is appropriate, neither too loose to cause the saw chain to fall off, nor too tight to cause the saw chain to break; appropriate tension can not only improve work efficiency, but also extend the service life of the saw chain; in order to further improve the comfort of operation, the shoulder strap is passed through the shoulder strap hanging ring 22 so that it can effectively share the pressure on the user's shoulders and arms during operation; this design can reduce the user's fatigue during long-term operation, increase the stability and comfort of operation, and enable the user to complete various operating tasks more easily; finally, the battery pack 21 is installed inside the battery slot 20 to ensure that the connection between the battery pack and the battery slot is firm and reliable; this design not only facilitates the replacement and installation of the battery pack, but also provides continuous power support for the device, so that the equipment can keep running for a long time in different working environments, thereby improving the work efficiency and practicality of the equipment.

[0030] Working principle: When in use, hold the rear handle 1 and insert the extension rod 9 into the lock head 6. Then align the positioning hole inside the extension rod 9 with the limit bolt 7. Then rotate the limit bolt 7 to make it penetrate the lock head 6 and the extension rod 9, thereby fixing the extension rod 9. Then rotate the T-shaped locking bolt 8 to make the lock head 6 close to the extension rod 9, thereby further tightening the extension rod 9 and achieving a stable connection.

[0031] Secondly, by sliding the guide plate 15 into the sprocket box 12, the guide plate 15 is aligned with the sprocket disk 16 inside the sprocket box 12 so that they are on the same horizontal line, and then the guide plate 15 is tightened, and the guide groove 17 is stably installed by fixing the bolts inside the guide groove 17. At this time, the saw chain is installed on the outer walls of the two sprocket disks 16. At this time, the chain tensioning adjuster 18 is adjusted to quickly adjust the tension of the saw chain to prevent the saw chain from falling off and breaking. The shoulder strap is passed through the shoulder strap hanging ring 22 to reduce the user's use pressure.
