Description

Ratchet wrench auxiliary control structure with switching mode

The creation department has a structure for switching the type of use, one of which is that when the ratchet wrench releases the work object or wants to lock, the ratchet joint rotation action of the small torque can be easily handled, and the work object is quickly taken. The structure of the lower or positioning device, and the second is the mode of use of the general ratchet wrench.

The ratchet wrench is one of the hand tools designed for tightening and disassembling the screw work such as the bolt and the nut, and is characterized in that the ratchet joint formed at the front end of the wrench handle is used for tightening or disassembling. Objects, and can produce different positive and reverse one-way manipulation and direction of force application.

Furthermore, the disassembly or tightening of the work piece can be achieved by the operation of applying a large torque to the hand held ratchet wrench, but when the work is to be taken out or positioned before being loosened or tightened, the user mostly gives up. The wrench tool is changed to the hand-held operation. The reason is that the work item after being loosened or tightened is in an easily rotatable state. If the wrench tool is used, it is not easy to work, so it will be improved.

Moreover, if the pneumatic or electric ratchet wrench currently on the market is used, although the above problems can be solved, due to the high cost of equipment and purchase, most of them are used by professional workers, so that they cannot meet the mass consumption. Economic demanders.

In view of the lack of use of the conventional ratchet wrench, the creator developed this creation based on years of experience in the manufacture of related products, and the main purpose is to use the shaft wrench front and rear switching structure configured by the ratchet wrench. To enable it to produce a snap-in or release mode in which the shaft controls the ratchet joint to reverse.

Another object of the present invention is to provide a separate positive and negative rotation action by the hand-pushing drive to control the rotation of the shaft in the wrench handle, thereby achieving a small torque operation.

Another purpose of this creation is that the structure design of the shaft can be switched back and forth through the shaft. In addition to the small torque operation for the hand rotation, the ratchet operation mode of the original large torque can be immediately restored, which is convenient for the operator. Quickly respond to the needs of various usage states.

With regard to the structural composition, technical means and efficacy of the present invention, only the examples of the preferred embodiment are further illustrated in the following:

First, as shown in Figures 1 and 2, the wrench body (10) of the present invention is mainly provided with a wrench handle (11) and a large round wrench head (12) coupled to the front end. The inner ring surface of the head (12) is provided with ratchet teeth (121) of appropriate pitch and can be placed into the ratchet sleeve joint (20), and the ratchet sleeve joint (20) is provided with a snap block on both sides (21). The latching block (21) is respectively engaged with the inner ratchet (121) of the wrench head (12), and the ratchet sleeve joint (20) is preset at the upper end of the latching block (21). There is an umbrella-shaped toothed ring (22), and a through slot (111) is formed in the wrench handle (11), and a ring groove (13) is preset at the rear end of the through-hole (111), and the wrench handle ( 11) The upper part is provided with a positioning member (14) extending through the slot (111); further, a threaded rod (30) is disposed in the through slot (111) of the wrench handle (11), and the shaft (30) A shaft ring (31) is formed at the front end, and a dial member (32) is coupled to the rear end of the shaft (30). The dial member (32) is provided with a plurality of external hole slots (321), and the shaft rod (30) A plurality of steel balls (33) having elastic members (331) are embedded and a ring groove (34) is dug.

Then, as shown in Figures 2, 3, and 4, when the shaft (30) is pushed inward, the shaft (30) steel ball (33) is locked in the groove of the groove (111) ( 13), while the shaft ring (31) is engaged with the umbrella ring (22) of the ratchet sleeve joint (20), and the ring groove (34) and the positioning member (14) are offset. The limit of the inward movement of the shaft (30) is provided.

Next, please refer to the figures 3, 4, 5 and 6 together. When the user turns the toggle block (32) to rotate in the forward or reverse direction, the shaft (30) can be linked in the same direction. Therefore, when the shaft (30) is given a downward rotation in a direction in which the ratchet sleeve joint (20) is engaged with the clamp block (21), the umbrella ring (22) is subjected to the shaft tooth. The ring (31) is pulled to cause the ratchet sleeve joint (20) to rotate clockwise. Conversely, when the shaft (30) is given upward rotation, the bevel ring (22) makes the ratchet sleeve The joint (20) is counterclockwise self-rotating author.

Furthermore, as shown in Figures 7, 8, and 9, when the shaft (30) is pulled outward, the shaft (30) of the shaft (33) is removed from the ring groove (13), and the shaft The rod ring (31) is disengaged from the umbrella ring (22) of the ratchet sleeve joint (20), so that the use mode of the general ratchet wrench is restored, and the positioning member (14) is moved to the ring concave The front end of the groove (34) is used to generate a limit structure for the shaft (30) to move outward.

In addition, as shown in Figures 10 and 11, the front end of the wrench handle (11) may be provided with a through hollow section (40), and a hollow ring (40) may be provided with a brake ring (41). The brake ring (41) can be worn and locked by the shaft (30), so that the user can selectively control the rotation of the shaft (30) through the dial block (32) or the brake ring (41). And the brake ring (41) can also provide a limit for the movement of the shaft (30) back and forth.

Only a good example of the existing creation is described here, and is simply illustrated by an illustration of the best mode that is expected to perform the existing creation, and several of the details can be improved with a number of distinct perspectives. Therefore, the above illustrations and descriptions are illustrative and not limiting.
