Description

Quick release structure of T-type ratchet wrench

This creation is related to the quick release structure of a T-type ratchet wrench, in more detail, in particular, it can be easily and quickly achieved by the simple operation of the fastening and quick release from the external set of accessories. Homework, and novel creations of practical value.

Press, generally, the ratchet wrench tool is mostly attached to its working end (usually set to a four-corner polygonal shape), and is attached to a sleeve or a screwdriver head of various sizes, etc. (depending on the work object). The external set components are inserted into each other, and the 俾 can conform to the corresponding size and shape of the workpiece being screwed, and fully expand the applicable range.

Therefore, when we are screwing a screw, there are a large number of such products that do not have any subsidiary mechanism between the plugging end and its external set fittings to prevent unintended shedding. Therefore, the unintended leftover condition of the socket assembly is often caused, which causes extreme inconvenience in operation; of course, if the two are combined due to the influence of foreign matter or a small difference in size, then There will be situations in which it is difficult to get rid of, and it is so uncomfortable for us.

Therefore, in view of the above situation, the creator relies on his years of practical experience in this industry and actively researches and develops. The creative party can come out as soon as possible, so it uses the card beads that can be easily controlled to connect externally. It is the most important purpose of this creation that the fittings are optimally fastened or quickly disengaged, thereby effectively preventing unexpected undesired shedding or loss of the two.

Yes, it is mainly located at the proximal end of the action handle, and cooperates with a sliding sleeve, an elastic member, a buckle ring, a top shaft and a card bead to form a quick release structure, so that the displacement can be performed by the sliding sleeve Order The card beads are then ejected or collapsed, and thus the intended purpose of achieving tight engagement and rapid disengagement with the external set of accessories is characterized.

In order to further understand the technical means and structural features of the creation, the preferred embodiment is described in detail with the drawings: First, please refer to the first, second and third figures, one of the original creations. Preferably, the ratchet wrench 10 is composed of a lateral force applying handle 11 and a longitudinal acting handle 12, and a ratchet reverse driving mechanism is provided at the intersection end of the two handle bodies 11 and 12. 13, the 俾 can control the direction of the force application; however, it is mainly at the near-polygonal insertion end 14 of the shank 12, with a sliding sleeve 15, an elastic member 16, a buckle 17, a top shaft 18 and a card The bead 19 constitutes a quick-release structure, so that the displacement of the sliding sleeve 15 causes the card bead 19 to be ejected or collapsed, thereby achieving an integral with the external assembly 20 (shown by a sleeve) The intended purpose of pressing and quickly disengaging is its characteristic.

The insertion end 14 of the shank 12 is provided with an axial deep hole 141 for inserting the top shaft 18, and is disposed on a side slightly above the insertion end 14, and is provided with a connection with the deep hole 141. a long-slot groove 142, and then a bead hole 143 is provided on the side of the insertion end 14 for inserting the bead 19; the sliding sleeve 15 is sleeved on the outer periphery of the action handle 12, and a through hole 151 is provided on one side thereof. After the locating pin 21 is inserted into the long-slot groove 142, it will be directly engaged in the corresponding slot 181 of the top shaft 18 to be in a linked relationship; the buckle 17 is buckled in the corresponding grooving groove 144 of the shank 12 The elastic member 16 is disposed between the buckle 17 and the sliding sleeve 15; further, the top and bottom ends of the top shaft 18 respectively have a card The groove 181 and the primary bead groove 182.

By the composition of the above components, in the normal state, the elastic force of the elastic member 16 will top the sliding sleeve 15, and at this time, the top shaft 18 will also be upwardly moved to cause the card bead 19 to be ejected by the level bead groove 182, and When the sliding sleeve 15 is pushed down, the top shaft 18 will also move down, so that the card bead 19 is in the released position, which is easy to say, as shown in the third and fourth figures, when it is intended to be inserted or disconnected from the external connection. When the assembly 20 is assembled, only the sliding sleeve 15 is pushed down first, so that the card bead 19 is in the falling position, and when the external force is removed, the card bead 19 will return to the ejected position, and the external assembly can be surely clamped. 20, so that it will not be easily separated.

Of course, since the ratcheting reversing drive mechanism 13 is a widely used hand-operated reversing drive unit that is widely used early, which is not the characteristic of the creative office, the creator will not repeat it, please also forgive me. .

Looking at the above, before the application, the creation of this creation has not only been found in similar products and related publications, but also has the practical value and positive benefits of "new" and "progress". Cheng has already met the application requirements of the new patent, and it is reasonable to obtain The protection of the patent law, 提出 apply in accordance with the law.
