Telescopic Baton

A telescopic baton, comprising:

• a plurality of tubes sequentially arranged in an embedded manner, wherein a tube on an inner side of two adjacent tubes in the plurality of tubes is capable of extending and withdrawing along an axis direction of a tube on an outer side of the two adjacent tubes, and a locking groove is formed in an inner wall of a first end of the tube on the outer side;
• a blade cam locking assembly comprising a socket sleeve, a plurality of blade cam blocks, a torsional spring and a fixing mechanism, wherein the socket sleeve is fixedly coupled to a first end, of the tube on the inner side;
• the plurality of blade cam blocks mare provided on the socket sleeve in a same circumferential direction;
• both extended ends of the torsional spring are respectively abutted against the socket sleeve and the plurality of blade cam blocks so as to enable the plurality of blade cam blocks to extend in a direction far away from a central axis of the socket sleeve, when the first end of the tube on the inner side extends to the first end of the tube on the outer side, the plurality of blade cam blocks are automatically clamped inside the locking groove under an action of the torsional spring;
• and
• an unlocking structure, wherein the unlocking structure is fixedly mounted inside a tube on an outermost side of the plurality of tubes, and the unlocking structure is used for driving the plurality of blade cam blocks to withdraw in a direction close to the central axis of the socket sleeve under an action of an external force so as to unlock the blade cam locking assembly.
