Description

Wrench set device

technical field

The utility model relates to a hand tool, in particular to a wrench set device which can provide the pulling function of an extended catch to improve applicability.

Background technique

The most commonly used equipment for many operations in the industry is hand tools. Although some highly technical and dangerous operations have been gradually replaced by machines, basic processing and maintenance must be completed with the assistance of hand tools. Therefore Manufacturers from all over the world are developing hand tool structures that are simpler, more humane, and have lower manufacturing costs.

According to different operations and environmental requirements, the shape of hand tools will naturally change. Generally, a common adjustable wrench is equipped with a fixed jaw and a movable jaw at the front end of a grip part. The movable jaw is connected to the fixed jaw with a screw. Movable setting, when the user adjusts the screw, the movable jaw can move closer to or away from the fixed jaw, so that the distance between the two jaws can be changed according to the size of the object to be clamped, so as to provide the effect of convenient clamping and applying force, and also Because the adjustable wrench is very easy to use, many people in the industry have improved it, adding components or changing the structure to make it produce additional effects.

For the existing adjustable wrench, please refer to the Taiwan Patent Application No. 91210322, "The Ratchet Structure of the Adjustable Wrench" patent, which is a ratchet structure of the adjustable wrench, which mainly includes a handle body, and one end of the handle body is An adjustable wrench part, and the other end is provided with a holding hole, and one end of the holding hole is provided with a space part, and the space part accommodates an elastic part and a stop block. There are ratchet catches of different sizes, and the outer peripheral ring is provided with ratchet teeth, and one end of the ratchet block is provided with a concave ring groove, one side of the buckle is clamped in the concave ring groove, and the other side is stuck against the container The abutting portion of the hole relative to the recessed ring groove enables the ratchet body to be fixed in the cavity; the end of the stop block opposite to the ratchet is provided with a claw portion, and the claw portion engages with the ratchet.

Although this kind of adjustable wrench can provide the effect of both movable clamping and ratchet turning, its ratchet block can only be used to pull the locking piece whose outer diameter can be locked with the ratchet, but in fact the type of locking piece With a high degree of variability, from screws, nuts, extension rods to sleeves, etc., all of them are gradually extended and evolved to meet the needs of the operation or to overcome operational difficulties. Even the locking pieces are differentiated according to different operation objects. Various sizes and types, and the ratchet block of this kind of adjustable wrench does not have the function of extending and pulling. If you encounter a locking piece that cannot be combined with the ratchet, this kind of adjustable wrench is useless Obviously, the types of locking pieces suitable for turning are quite limited, so its practicability is poor. It is necessary to develop a design that can provide extended locking and pulling functions in addition to the ratcheting and turning functions.
