The bushing member 8b has three pawl-escapement-producing cams 42 formed on the flange 8b<SP>1</SP>. Three pawls 35 are provided, each pivotally mounted in a cavity in the inertia member 17. During relative angular movement between the driving unit and the inertia assembly escapement and resultant impact operations of the pawls 35 on successively engaged ratchet teeth 38 occur followed by triggering action of the pawls to release the energy stored in the spring S and cause the impact. Sockets 58 are provided in top and bottom walls of the casing 8 for engagement by the lugs 57 of a bar spanner 56. Alternatively, torque imput may be applied to the axially exposed bushing portions 45, 45<SP>1</SP> of the bushing members 8a, 8b.

SHIPPING TOOL FOR APPLICATION OF PRIORITY POWER

Torque tool for tightening or loosening connections, and method of tightening or loosening the same

A torque tool for tightening or loosening connections has a driving element engageable with a turnable part of the connection for turning the turnable part of the connection for tightening or loosening the connection and turnable about an axis, and a power drive configured for acting on the driving element such that the drive acts on the driving element to turn the driving element and thereby to turn the turnable part of the connection over a partial stroke and a space is formed between the drive and the driving element, and the drive is then displaced over the space toward the driving element to act again on the driving element to turn the driving element and thereby to further turn the turnable part of the connection over a further partial stroke.

Method of setting a drop-in anchor

The present invention relates in general to the field of securing structural members to masonry, and more specifically, to a drop-in anchor setting tool and method of use. The drop-in anchor setting tool includes a hands-free safety feature that allows the drop-in anchor and setting tool to remain embedded in the masonry during installation. In particular, the drop-in anchor setting tool includes a threaded portion configured to screw together the drop-in anchor and the drop-in anchor setting tool during installation. A purpose of invention is to provide a drop-in anchor setting tool and method of use that minimizes risk of injury to the operator during installation, is easy to use, and cost-effective to manufacture.

Socket wrench

A socket wrench includes a handle (10) having a housing (12), a drive shank (13) having a ratchet wheel (131) mounted in the housing, two pawl members (16) engaged with the ratchet wheel, a switching member (15) located between the pawl members, two elastic members (S) each biased between the housing and the respective pawl member, a control knob (14) connected with the switching member, a driven arm (21) having a mounting sleeve (20) and an arcuate mounting slot (22), a connecting plate (17) provided on the handle, and two driving arms (18; 19) provided on the connecting plate and received in the mounting slot. When in use, one of the driving arms drives the driven arm by a leverage to drive the drive shank to rotate a socket (30a) to operate a workpiece in an energy-saving manner.

Underground fire-hydrant spanner for fire-hydrant installed below pavement or footpath in small lined fire-hydrant trough in road, has transverse pipe arranged at end of prolonged profile and connected with profile over diagonal bar

The spanner (1) has a prolonged profile (2) and an arbor (8) that is provided at an end (3) of the prolonged profile. The arbor is plugged under a bar of a fire-hydrant lid. A hammer mechanism includes a hammer (11) that is moved along the prolonged profile, and a stop unit (12) for the hammer is provided at another end (4) of the prolonged profile. A transverse pipe (6) is position-fixedly arranged at the former end of the prolonged profile and connected with the prolonged profile over a diagonal bar (7). A spanner nut piece (17) is arranged at the latter end of the prolonged profile. The spanner nut piece is designed as a square recess.
