Description

Quick wrench

The present invention provides a technical field of a wrench, in particular, a technically provided quick-wrench, in which a fixed-head integrated wrench head is obliquely provided with a second-order stepped groove, and the extension rod of the movable jaw is set to slip, and The cover of the cover is fixedly fixed, the extension rod is provided with a long groove, and a joint pin passes through the round hole, the long groove and the through hole, and the extension rod and the fixed cover and the wrench head are restricted, so that the clamp can be manually and quickly clamped The screw head or nut is adjusted.

According to the first patent application No. 92119982, the "returnable quick-turn type open end wrench" invention patent case has an abdomen, a fixed claw is protruded from one end of the abdominal body, and a servo claw is disposed on The other end of the abdominal body and the fixed claw form a predetermined spacing jaw, and the main abdomen and the servo claw joint form a lower groove having a partial circular section larger than a semicircular shape; the servo claw and Forming an upper groove at the abdomen joint, having a circular cross section smaller than a semicircular shape, the circular diameter is slightly larger than the circular diameter of the lower groove, and matching with the lower and lower grooves of the abdomen to form a receiving hole; The servo claw is provided with a protrusion adjacent to the upper groove, has a section corresponding to the section of the lower groove to linearly move along the lower groove; and an elastic device, It is placed in the accommodating hole so that the stud of the servo claw normally resists the abdomen and can linearly move linearly with respect to the abdominal body to expand the predetermined interval. Although the above-mentioned first case can expand the predetermined pitch, the convex column is used as a spring abutting manner, the moving distance is limited, and the movement uses the hole groove.

See the second patent application No. 101129348, the "wrench" invention patent, which includes a main body, a crotch portion, a grip and an elastic member. The main body is provided with a fixed jaw and a chute. The crotch portion is provided with a movable cymbal, the bottom end of the movable cymbal forms a sliding portion, the sliding portion is concavely provided with a card slot, and the sliding portion is defined away from the bottom side of the movable cymbal and the abutting portion of the main body away from the bottom surface of the main body of the sliding groove At the interface, the extension of the interface passes through the card slot. The handle is provided with a dialing member. When the handle is in the driving position, the dialing member pushes against the sliding portion, and the interface extends through the dialing member. The movable jaw can be displaced away from the fixed jaw when the handle is in the release position. Thereby, the invention can completely transmit the force of the wrench to the movable jaw and the fixed jaw, so that the invention is easy to drive the workpiece to rotate, and the structure of the invention is simple and helps to control the production cost. The second conventional case is similar to the conventional adjustable wrench. The difference is that the worm and the worm wheel are eliminated and replaced by springs and pins. The sliding is also in the form of a slot.

A pin hole is formed through the circular hole, and the pin hole is also aligned with the cylindrical tube. The long slot, a pin is worn when the cylindrical tube group enters the round hole, and is inserted through the pin hole and the long slot hole to fix the movable clamp, which can only slide and not swing, and the cylindrical tube forms at the bottom end. Screw hole, and after the pin is fixed, it can be easily filled into the spring and locked into the screw hole to fix the position of the spring. The fixed clamp and the top of the movable clamp are provided with an arc hook to make each The clamps have a range of two angles and three faces to avoid slippage. The third case of the conventional use uses a circular hole to match the spring.

Refer to the fourth patent case of the "Opening Wrench" invention patent application No. 200710194815.8, which comprises a handle, a clamping body formed at one end of the handle, a clamping seat, and a positioning pin. And an elastic piece. The accommodating body includes a receiving slot for accommodating a screw lock member, a first clip and a second clip on the two sides of the accommodating slot, and respectively disposed on the second clip a receiving hole and a jack, the clamping seat includes a sliding rod inserted into the receiving hole and movable, a clamping piece formed on the outer end of the sliding rod, and a long perforation disposed on the sliding rod . The positioning pin is inserted into the insertion hole and passes through the long perforation. The elastic member is configured to move the clamp seat toward the handle. Thereby, the invention has the characteristics that the screw lock can be quickly clamped and positioned, and the use is convenient. The fourth case is also a way of fitting a round hole with a spring.
