The present invention is to provide a police baton including an outer tube and an inner tube connected in a telescoping manner, and clutch locking and releasing mechanisms provided at first ends of the inner and outer tubes respectively. When the inner tube is moved outward of the outer tube until the first end of the inner tube presses against a second end of the outer tube, a clutch locking block of the clutch locking mechanism moves laterally outward due to an elastic force and is embedded into a retaining groove on the outer tube, thereby forming a long stick. When a releasing shaft of the releasing mechanism is inserted into a releasing groove on the clutch locking block, the clutch locking block is moved laterally inward and released from the retaining groove, thereby allowing the inner tube to move toward the outer tube for forming a short stick. |

1. An expansion/collapse control mechanism for a police baton, the police baton having an outer tube and an inner tube telescopically connected to the outer tube, the expansion/collapse control mechanism comprising:
a clutch locking mechanism provided adjacent to a first end of the inner tube, the clutch locking mechanism comprising at least a clutch locking block and at least an elastic member, the elastic member having two ends respectively pressed against the clutch locking block and an inner wall of the inner tube, the inner tube having a second end which can pass through the outer tube by way of a first end of the outer tube and be exposed from a second end of the outer tube, a retaining groove being provided on an inner wall of the outer tube and adjacent to the second end of the outer tube, wherein when the inner tube is forced to move outward of the second end of the outer tube such that the first end of the inner tube is pressed against the second end of the outer tube, the clutch locking block is moved laterally outward by an elastic force of the elastic member and becomes embedded in the retaining groove; and a releasing mechanism fixedly provided at the first end of the outer tube and comprising a releasing shaft, the releasing shaft having a first end to be forced by a user and a second end extendable into the inner tube by way of the first end of the outer tube so that, when the clutch locking block is embedded in the retaining groove, the second end of the releasing shaft can be inserted into a releasing groove formed on the clutch locking block by pressing the first end of the releasing shaft such that the clutch locking block is moved laterally inward, released from the retaining groove, and no longer embedded in the retaining groove, allowing the first end of the inner tube to move toward the first end of the outer tube when being forced. |
