Description

Steerable easy combination wrench

The present invention provides a technical field of a wrench, in particular to provide a steerable and easy-to-assemble wrench, wherein the dial and the driving head can be pre-assembled, and the two movable blocks are not connected to the concave arc groove to connect a bump, and the whole wrench Less components, good strength and easy assembly.

For the new patent case of the "Reversing Ratchet Wrench", the handle head of the wrench is divided into two compartments, one drive head, which is placed in one of the compartments, and is driven around the head. Driving the tooth portion, one direction dial is arranged in the other compartment, and can be cut at an angle from left to right. Two dice are respectively provided with a plurality of ratchet teeth for engaging the driving tooth portion, and the stack of the dice are arranged at two partitions. In the middle of the room, the direction button forces the forceps to engage the driving tooth, and there is a tooth difference between the two dice. When the direction button is in one position, the two dice are forced against the head on the side of the inner wall of the middle portion. The wrench can be idling in one direction, and the direction button is placed in the other position, forcing the two scorpions against the head on the other side of the inner wall of the intermediate portion, and the wrench can be idling in the other direction.

However, in the above-mentioned prior case, the two dice have respectively dug a groove, and one of the dice also has a slot, so the basic strength Poor, but the composition of the prior case, except for one direction knob, two elastic members, two ejector pins, one O-ring, two rafters, one handle, one pressure bar, one steel ball, one Elastic parts, two O-rings, one drive head, one sealing plate and one hoop, the components are quite complicated and complex, and the assembly direction is set with no through holes, so the elastic parts and the ejector pins and the rafters are It is loaded in the same direction. However, when the driver is mounted, the tweezers need to be pressed, and the two tweezers are not easily pressed, so that the driving head is not easy to install, and assembly is difficult, and improvement is necessary.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, the consumers are eagerly awaiting, and the relevant industry must strive to develop the goal and direction of breakthrough.

In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

The main purpose of the present invention is to provide a steerable and easy-to-combine wrench, wherein the dial and the driving head can be pre-assembled, and the two swaying blocks are not connected to the concave arc groove to connect a bump, the strength is better, the wrench has less integral components and strength. Good and easy to assemble.

In order to achieve the above object, the present invention provides a steerable and easy-to-combine wrench, which comprises: a wrench handle and a head integrally formed, the head is provided with a first and a second groove chamber; and a button is provided, the foregoing Dials are provided throughout Second-order hole, second-order hole for second-order ejector and two springs are assembled from the rear to complete pre-assembly of the button; the button is set into the second slot; Through a concave arc groove to connect a bump, so the strength is better, the two bumps can just abut each other, and then the first groove chamber is arranged to the first and second groove chambers, and the two protrusions are arranged in front of the button. a slot is provided for the card to be engaged, and the two-stage shaped ejector pin is forwardly facing the concave arc groove; a driving head is provided with an axial stepped through hole, and an elastic component and a pressing bar are provided from the upper group to the lower group And a radial hole is forced into a steel ball at the front end of the driving head, and the steel ball can limit the movable range of the pressing rod, thereby pre-assembling the driving head, and then assembling the driving head into the first slot of the wrench head, driving The ratchet teeth of the head circumference are engaged by the ratchet teeth of the two movable blocks which are spaced apart from each other by the ratcheting teeth. Finally, the buckle head is driven by a buckle spring to fasten the head ring groove to achieve the structural strength of the wrench. Good and easy to assemble components.

With regard to the techniques, means and functions of the present invention, a preferred embodiment is described in detail with reference to the drawings, and it is believed that the above objects, structures and features of the present invention can be obtained from an in-depth and specific understanding. .
