Abstract
A clamping device includes a rod slidably received in a channel of a housing, a catch plate and a release panel slidably engaged onto the rod and biased to be released and engaged onto the rod. A hand grip is pivotally secured to the housing, a pawl is rotatably secured in the housing and has one end engageable with the hand grip and the other end engageable with the catch plate to tilt the catch plate relative to the rod and for allowing the rod to be moved relative to the housing by the hand grip and the pawl. A knob may move and release the release panel relative to the rod.

A clamping device comprising:
- a housing including an upper portion having a channel formed therein, and including a lower portion having a handle provided thereon,
- a rod slidably received in said channel of said housing,
- a catch plate and a release panel each having an orifice formed therein for slidably receiving said rod, and for slidably engaging said catch plate and said release panel onto said rod,
- a first biasing means for biasing said catch plate toward said release panel and to release said catch plate relative to said rod,
- a second biasing means for tilting said release panel relative to said rod and to releasably lock said rod to said housing,
- a hand grip pivotally secured to said housing with a pivot shaft, and including a seat provided thereon, and
- a pawl rotatably secured in said housing, and including a first end engageable with said seat of said hand grip, and a second end engageable with said catch plate to tilt said catch plate relative to said rod against said first biasing means.
