Description

Double-push button ratchet wrench

The invention relates to a double-push button ratchet wrench, which mainly endows the ratchet wrench with a dial button on the upper and lower ends, and makes the upper and lower dial buttons can rotate synchronously, according to which the reversing effect of the ratchet wheel is controlled .

At present, most of the traditional two-way ratchet wrenches on the market are only equipped with a toggle button on one side of the wrench, so that the user can toggle the stopper inside the ratchet head to switch the stopper to change the ratcheting direction of the ratchet.

However, in order to meet the needs of different use environments and operators, it is hoped that in the convenient operation of the two-way wrench, the fluency of its operation will be improved, and the configuration of its reversing structure is increased to meet the needs of users in various situations.

In view of improving the smoothness of the use of the conventional ratchet wrench dial control structure, the inventor has developed this invention based on years of experience in the manufacture of related products, and has made special improvements to develop this invention, the purpose of which is to configure a linked dial on both the upper and lower ends of the wrench No matter whether the upper or lower dial is turned, the dial control part of the upper dial can control the front stopper block to catch with the ratchet, so as to achieve the change of the ratcheting direction.

Another purpose of this creation is that, through the design of the snap-in connection between the upper dial fan-shaped hole and the lower dial fan-shaped column, no matter you turn the upper dial or the lower dial, you can make the two rotate synchronously. move.

Regarding the structural composition, technical means and efficacy of the present invention, only the illustrations of the preferred embodiments are used in conjunction with examples to further explain in detail:

First, please refer to FIGS. 1 to 6, the present invention is mainly provided with an accommodating part (12) in the driving part (11) of the wrench (10), and the inner rear end of the accommodating part (12) has A connecting groove portion (13) is arranged, and an upper button groove (14) is arranged at the rear end of the groove portion (13), and a communication hole (15) is dug in the upper button groove (14) ), and the lower end of the communication hole (15) is provided with a lower button groove (16), the inner side of the lower button groove is preset with a ring groove (17); wherein, the accommodating portion (12) is available for A ratchet wheel (18) is set on the card holder, and two latching blocks (40) opposite to each other are provided in the latching groove (13). The tip of the latching block (40) must be engaged with the ratchet wheel (18). And the detent block (40) is dug from the rear face with a perforated hole (41) penetrating to its inner end face, and the two detent blocks (40) are provided with an elastic member (42) between two opposite sides; The upper dial button slot (14) is provided with an upper dial button (20). The upper dial button (20) is composed of a limit portion (21), a retracted portion (22) and a dial control portion (22) The upper dial button (20) is formed with a fan-shaped contact hole (24) dug inwardly, wherein the dial control portion (22) is pressed against the dialed perforation (41) of the two end detent blocks (40) ), which then generates the positioning of the upper dial button (20) in the upper dial button slot (14); and the lower dial button slot (16) is provided with a lower dial button (30), a lower dial button (30) An outer concave portion (31) is provided on the outer edge, and a fan-shaped plug post (32) protrudes from the upper end. The fan-shaped plug post (32) can penetrate the communication hole (15) and be inserted into the fan of the upper dial (20) In the type contact hole (24), the lower dial (30) is clamped in the inner recess (31) and the ring groove (17) by a C-shaped buckle (33), according to which the lower dial (30) is reached ) In the lower button slot (16).

Therefore, by rotating the locking structure of the fan-shaped contact hole (24) of the upper dial (20) and the fan-shaped pin (32) of the lower dial (30), the operator can rotate the upper dial (20) no matter what Or the down dial button (30), both the up dial button (20) and the down dial button (30) can be synchronized to rotate, and the up dial button (20) dial control part (23) can be moved deeper into the latch The block (40) is received in the dial perforation (41), and then pulls the moving block (40) to move toward the inner rear end, and at the same time, the elastic member (42) between the moving blocks (40) presses the other end to move The block (40) snaps against the ratchet wheel (18) at the front end, thereby reaching the change of the ratcheting direction.
