Description of the Invention: [Technical Field] The present invention relates to an open-type plum blossom gear wrench, which comprises a body, a brake group and a collar set, and is mainly used for disassembling a polygonal nut or a screw head. In the implementation, the use of the ratchet rotation mode allows the open-type wrench to be more labor-saving when the component is locked, and the brake group is provided at the connection between the grip and the bump of the body when the force is applied. The force points are concentrated on the brake group ' to avoid the wrench collapse and damage, which is a product that fully meets the industrial applicability. [Prior Art] According to the 'practical ratchet wrench structure with a high torque value, as in the Republic of China Patent Application No. 091215517, a ratchet wrench structure having a high torque value, which mainly includes a grip, the grip end The driving unit has a receiving portion, and the receiving groove is formed with a receiving groove for receiving the ratchet block Q' The ratchet has an inner peripheral portion and an outer peripheral portion, and the inner peripheral portion forms a driving hole for arranging and driving the workpiece; and the outer peripheral portion is provided with a ratchet tooth, and the ratchet tooth peak to the ratchet center Forming a corresponding angle between the points, the angle is between 4 degrees and 2 degrees; and the swaying block is provided with a swaying tooth relative to the ratchet, and the flank angle of the swaying tooth is at least a ratchet tooth Corresponding angles between the corresponding tooth faces, and the tooth thickness is not greater than the tooth thickness of the ratchet teeth, and the structural functions of the present invention can be achieved by the above structure. 5 201014683 Specialized open-end wrenches, such as the open-end wrench of the Republic of China: 1:410 with a ratchet function - with a shank - one end, the head 9, the two sides of the accommodating groove Two opposite sides, the two parallel sides of the 俾 bolt are matched, the middle 俾 is provided by the / screw, and the groove is formed. The groove is opened and inclined: the bolt rotates in this space, and The upper opening is provided with a 1= hole, and the one end of the step hole is connected with the groove to form the class rod, and the holding assembly is composed of an elastic element and a clamping groove assembly axial groove, the axial groove In the supply room, the control unit is set to hold the rod, and the limit component is disposed in an accommodation space. [Summary of the Invention] The bow 1 uses the 14 technique "ratchet with high torque value:::piece:: the use of the upper force is too large and easy to wrench the second = ❹ the power technology "with the ratchet Wei open the tons" Use-produce: can not fix the clamping nut or bolt head, and the rotation can make the above # phenomenon not effective (four) rotation system, in view of the ancient and the drawbacks, the inventor believes that it is urgent to improve, the needle The invention is based on the design of the open-type plum blossom gear of the present invention, which is in accordance with the practical design. The invention is capable of tying or clamping more angles by means of a ratchet-type open-ended wrench. In order to turn the detacher. The invention discloses an open-type plum gear wrench, [see the first figure and the figure], which comprises a body (1), a brake group (2) and a collar group (3) 6 201014683; wherein: the body (1) refers to The integrally formed grip (4 i) is provided with an annular projection (丄2) at the end of the grip (1 1), and a groove (121) is provided at the middle of the projection (work) class, the groove (121) can be combined with the collar (3 1) of the sleeve group (3), and an opening (1 22) is opened at an outer portion of the outer edge of the projection (12), and the opening (1 22) can be clamped With a polygonal nut or bolt head, a combination hole (work 3) can be set on the left and right sides at the connection between the handle (丄丄) and the bump (丄2), which can be combined with the brake group (2). The angle of the combined hole (丄3) must be greater than the width of the opening; the brake group (2), [please refer to the fourth figure together] is composed of the brake block (21), the elastomer (22), and the fixed block (23). The brake block (21) is a convex type block, and the top end thereof is serrated (2) and can be locked with the collar (3 1) of the collar group (3) (see the third figure). Elastic at the rear end of the brake block (2 1 ) (2 2), the elastic body (2 2) can be a compression spring to make the brake block (2 1) have an automatic return function, and a fixed block (23) is arranged at the rear end of the elastic body (2 2), the fixed block (2) 3) Fixing the brake block (2 1) and the elastic body (2 2) to prevent the component from popping off; the collar set (3) consists of the collar (3 1) and the retaining ring (3 2), the collar (3 1) is a ring-shaped component, the circumference is set in a zigzag shape, which can be combined with the brake block (2 1) of the brake group (2), and a groove is provided on the outer edge of the collar (3 1 ) (3 χ χ ), the fixing ring (3 can be placed inside, in the collar (3 n - end opening with collar opening 201014683 = clamping fixed polygonal nut or bolt head, its fixing ring (32) is clothing (3 1 The object connected to the body (work) and provided with the opening of the fixing ring (3 21). [Embodiment] When the group 5 implements the open-type plum gear hand, first (please participate in the third and fourth figures) 〕 Set the collar (3 i) of the collar set (3) to the groove (1 2 1) β of the projection (1 2) of the body (1), and use the retaining ring of the collar set (3) ( 3 2) Consolidate the collar (3 i) with the body (work)疋This way, the gj ring (32) can be prevented from being squeezed by any squeeze and the brake block (2 1) of the brake group (2) can be assembled into the combined hole (1 3) of the body (1). The rear end of the block (21) is sequentially provided with an elastic body (2 2) and a fixed block (23). When implemented, the open-type plum gear wrench of the present invention (see the fifth figure) is disassembled. Or when assembling a polygonal nut or bolt head, align the opening (1 2 2) of the projection (1 2) of the body (1) and hold the solid β fixed nut or bolt head to the collar set (3) Inside the collar (3 workers), hold the grip of the body (1) (ii) and pull the body (i) to make the collar (3 1) of the collar set (3) rotate in one direction. By the engagement of the brake block (2 1) of the brake group (2) and the collar (3丄), the point of application of the grip (work 1) is concentrated on the brake group (2), and the polygon is rotated. The nut or bolt head makes the outer edge of the annular projection (i 2) of the body not easy to collapse. According to another embodiment of the present invention, [see FIG. 7], the body (1) can be set as a single side, and a rotating hole is formed in the handle (1 1 ) (tool 8 201014683 4), which can be matched with a ratchet tool (4). ▼,—You move, 1 ft + forged to the effect of smashing and locking. ❹ ❹ When using the invention, 'use the ratchet to rotate, so that the wrench is more labor-saving when it is swaying, suitable for narrower The space is disassembled; the brake group (2) is disposed on the left and right sides of the joint between the shank (11) and the projection C12 of the body (1) on the urging force, and the force application point can be concentrated on both sides When the nut or the bolt is locked, it is not easy to collapse the holding part, and the fixing ring (32) has a notch instead of a complete circular ring, which is not allowed to be squeezed during the tightening process. There are doubts about deformation, and the general city circular ring, less susceptible to deformation. In summary, it is to be understood that the present invention is novel, and the present invention is not disclosed in any publication, and is in compliance with the provisions of Articles 21 and 22 of the Patent Law. The above description is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is to say, it is within the scope of the patent application of the present invention. Equivalent changes and modifications made by the company shall remain within the scope of this invention. ζ 201014683 [Simplified illustration of the drawings] - Figure 2 is a schematic view of the assembly of the present invention.
