Description

Inserted card structure of a hole type ratchet wrench

The creation department is related to the embedded card structure of a socket type ratchet wrench. In more detail, it particularly refers to a method capable of stably inserting an external sleeve and an external conversion head so as not to cause undesired falling off conditions and affecting operation. The novel creation of smoothness.

According to the so-called "ratchet wrench", it refers to a professional type wrench with a ratchet steering mechanism to control the direction of the driving force. The so-called "sleeve type" ratchet wrench is specifically designed to design a ratchet end. Form a hollow sleeve for the use of external components such as external sleeves or external adapters (see components shown in Figures 6 and 7), etc., and use the screws (not shown) to anticipate Control the direction of the rotation.

Of course, although these conventional socket-type ratchet wrenches have long been used for many years, they have long been familiar to the operators in use, but they have always been stuck between the external sleeve and the external conversion head and the hollow sleeve hole. The buckle method can only be generated by the holding of a top bead (located on the side of the external sleeve and the external conversion head) or a loop (provided on the inner edge of the hollow sleeve). A certain degree of combined strength is not easily detached; however, it is well known that when the wrench is applied, it is highly likely that the external sleeve and the external adapter will be caused by the collision with the surrounding objects or the excessive shaking of the operator itself. The force is separated from the hollow sleeve hole, thereby impairing the smooth operation of the construction, and may even cause the loss of the external sleeve and the external conversion head or the difficulty of picking up the situation, thereby causing a situation that is more difficult to clean up. Such custom designs are necessary to be improved.

Therefore, in view of the above facts, the creator has been familiar with the industry for many years. Experience, active betting and active research and improvement, this creation was born early; therefore, it is mainly aimed at how to prevent the unexpected detachment between the external sleeve and the external conversion head and the wrench, and effectively maintain the construction time. The overall operation is smooth, and at the same time, it does not cause unnecessary losses due to such situations, but can indeed add its practical value, so that it no longer becomes an additional trouble for the operator, and is the main purpose of the creation.

Yes, it is mainly connected to the ratcheting head end of the wrench body, and is provided with a shallow groove adjacent to the hollow sleeve hole, the center of the shallow groove has a positioning bolt hole, and the reversing cutting button and the positioning bolt of the ratchet assembly are inserted. a knot, wherein, under the reversing cut button, an insert having an outer shape similar to a shallow groove profile and having an insert portion, a long hole and a pusher portion is placed first, and is disposed at a head end of the wrench body near the ratchet a collar for accommodating a hole is formed in cooperation with the locking component for inserting an elastic body, and the corresponding end of the pusher portion of the panel is also inserted into the receiving hole, and is composed of an elastic body By the composition of the above components, the embedded portion of the insert can protrude into the end of the hollow sleeve end of the ratcheting head end, and can be firmly embedded in the external sleeve and the external conversion head. Corresponding to the ring groove, so that it does not cause undesired shedding phenomenon.

In order to further understand the technical means and structural features of the creation, a preferred assembly embodiment is described in detail with a number of drawings: First, please refer to the first, second and third figures, which is a preferred assembly embodiment of the present invention. As can be seen from the figure, it comprises: a wrench body 10, one end of which has a ratchet effect with a ratchet assembly 20. The head end 11 is provided with a hollow sleeve hole 12 corresponding to the ratcheting head end 11 , and then a shallow groove 13 is disposed adjacent to one side of the hollow sleeve hole 12 , and a positioning bolt is arranged in the center of the shallow groove 13 The hole 14 is inserted into the reversing cut button 21 of the ratchet assembly 20 and the positioning bolt 22; an inlay 30 is disposed under the reversing cut button 21, and its appearance is similar to the shallow groove 13 contour. And the flat groove 13 is placed in the shallow groove 13 respectively, and has a fitting portion 31, a long hole 32 and a pushing portion 33; a set of rings 40, which cooperate with the locking member 43 and the corresponding hole position 42 to be locked to the wrench body 10 The corresponding screw hole 15 of the ratchet end 11 has a receiving hole 41 thereon for inserting an elastic body 44, and the corresponding end of the pushing portion 33 of the panel 30 is also inserted into the receiving portion. The hole 41 is held by the elastic body 44.

Therefore, as shown in the fourth and fifth, by the composition of the above components, the fitting portion 31 of the panel 30 can protrude into the end of the hollow sleeve hole 12 of the ratcheting head end 11, so that the outer sleeve is After the cartridge 50 is inserted into the hollow sleeve hole 12, it can be firmly embedded in the corresponding annular groove 51 of the external sleeve 50 so as not to cause undesired falling off. When the external sleeve 50 is to be removed, Only by the action of the panel 30 pushing the jaws 33 and moving in the opposite direction (see the fifth figure), the panel 30 of the panel 30 can be disengaged from the annular groove 51 of the outer sleeve 50, so that it can be easily removed. And the installation and replacement, in particular, the movable displacement of the panel 30 will not affect the smooth manipulation of the reversing cut button 21 of the ratchet assembly 20.

Of course, since the ratchet assembly 20 and its reversing cut button 21 and the positioning pin 22 are a conventional member, it is not the feature of this creation claim, so it will not be described, please inspect.

Furthermore, as shown in the sixth and seventh figures, the present invention provides a simple replacement operation for the external sleeve 50 or the external conversion head 60, and the external sleeve 50 and the external conversion head 60 are also provided. The groove grooves 51 and 61 which can be engaged with the insert 30 of the panel 30 and which can be inserted into each other.

Looking at the above, this creation is not only not seen in the market for similar items before the application. Relevant publications literature, and already have 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, and apply in accordance with the law.
