Abstract

A clutchable pry bar includes a bar member with a fitting connector; a rack member fitted with the fitting connector of the bar member, including two slots adjacent to a closed end of the rack member, and including two through holes proximate to an opened end of the rack member; a ratchet shaft inserted to the through hole of the rack member, and including a first end portion disposed on one end thereof; at least one ratchet member fitted to the ratchet shaft, a plate member movably fixed to the slots of the rack member, a returning spring between pegs of the plate member and a central extension of the bar member; a stem member to be retained with the ratchet shaft after the stem member is inserted to a radial bore of the ratchet shaft.

Claims

1. A clutchable pry bar comprising:

a bar member;

a rack member formed in a U shape to be fitted with a fitting connector of the bar member, including two slots arranged on two sides thereof individually adjacent to a closed end of the rack member, and including two through holes defined on the two sides thereof respectively proximate to an opened end of the rack member;

a ratchet shaft inserted to the two through holes of the rack member; and

including a first end portion with a radial bore disposed on one end thereof;

a locking member for locking the ratchet shaft to another side of the rack member;

at least one ratchet member fitted to the ratchet shaft, wherein the ratchet member includes a plurality of toothed recesses arranged around an outer periphery thereof;

a plate member movably, fixed to the two slots of the rack member, including a toothed block to engage with the ratchet members, and including a number of pegs extending outward from the toothed block relative to the closed end of the rack member;

a returning spring between the pegs of the plate member and a central extension of the bar member so that the plate member moves between the two slots of the rack member;

a stem member, including a large-diameter segment, inserted through the radial bore of the ratchet shaft, and including at least one ball mounted thereon to retain the stem member with the ratchet shaft after the stem member is inserted to the radial bore of the ratchet shaft.

2. The clutchable pry bar as claimed in claim 1, wherein the bar member includes a fitting connector fitted on one end thereof.

3. The clutchable pry bar as claimed in claim 2, wherein, the fitting connector includes a central extension disposed on a top end surface thereof.

4. The clutchable pry bar as claimed in claim 1, wherein the rack member includes an opening defined on the closed end thereof, and each slot includes a cutout formed thereabove.

5. The clutchable pry bar as claimed in claim 1, wherein the ratchet shaft includes a stopping shoulder connected with the first end portion and extending radially from an outer rim thereof, and includes a second end portion mounted on another end thereof to be inserted to the holes of the rack member, such that the first end portion of the ratchet shaft is limited outside the rack member by using the stopping shoulder, and the second end portion includes two opposite tangent planes fixed thereon individually, and includes an aperture formed therein.

6. The clutchable pry bar as claimed in claim 1, wherein the locking member includes a lock ring and a bolt.

7. The clutchable pry bar as claimed in claim 1, wherein the ratchet member includes a central orifice defined thereon and corresponding to two opposite tangent planes of the rack member.

8. The clutchable pry bar as claimed in claim 1, wherein the plate member includes two bosses mounted on a top surface of the toothed block and corresponding to the cutouts of the slots.

9. The clutchable pry bar as claimed in claim 8, wherein the bosses are inserted through the cutouts of the slots to be retained on two inner walls of the two sides of the rack members, such that the plate member is positioned in the slots.
