The locking device is used to fix the trekking pole. After adjusting the length, the locking device is used to fix the trekking pole.
According to the locking method, there are two main types of trekking poles: outer lock and inner lock.
Outer lock:
The principle of the outer lock is to set an elastic buckle on the connection part of the trekking pole, the length of the trekking pole can be adjusted by opening the fastener, and the trekking pole can be fixed by closing the fastener. It is characterized by good locking force and convenience, suitable for users with relatively small hand strength, and can be easily locked and unlocked when wearing thick gloves.
Internal lock:
The principle of the inner lock is to adjust the friction between the expansion bolt and the inner wall by holding the two sections of the trekking pole and rotating in different directions. This locking is reliable, but has certain requirements on the user's hand strength. If it is not tightened, the trekking pole may retract during use, so be careful.
The natural environment also has a great influence on the choice of trekking poles. If the route environment is wet and cold or the climate is changeable, it is sunny and rainy, then it is best to choose an external locking trekking pole. Because the rod will be wet and slippery after the rod is wet, and the cold environment will cause hand weakness, which will make the inner lock difficult to lock and unlock.
