Description

Palm-type ratchet wrench structure

This creation is related to the structure of a palm-shaped ratchet wrench. In more detail, it refers to a kind of unavoidable fall-off condition of the workpiece and the screw workpiece, and can accelerate the screwing efficiency of the screw workpiece, thereby enhancing its A novel creation of practical value and ease of operation.

Press, as shown in the seventh and eighth figures, the so-called palm-type ratchet wrench 10 is specifically intended to be held on the palm of the user, so that the ratchet drive head 12 with the control knob 11 at one end is exposed outside the tiger's mouth. Then, the screwdriver head 14 is inserted by the ratchet driving head 12 and the working end 13 of the polygonal insertion hole (not shown), and the screw workpiece (not shown) is screwed.

Moreover, the conventional palm-type ratchet wrench 10 is provided with a hidden magnetic member (not shown) or a side end face in the inside of the working end 13 in order to avoid unintended falling off of the inserted screwdriver bit 14. Add a card bead 15 to strengthen the insertion force between the two.

However, it is well known that due to various factors such as the working environment and usage habits, such conventional products are in fact extremely prone to the situation in which the screwdriver head 14 is detached from the working end 13, thereby causing unnecessary troubles in use, and the reasons may include The external factors such as strong waving, shaking, or even collision with foreign objects, as well as the inevitable factors such as the magnetic demagnetization of the magnetic parts and the gradual wear of the beads 15 will make this product unsatisfactory for a long period of time. The state can be used to detract from its practical value and ease of use.

Therefore, in view of the above facts, the creator relies on his practical experience of practicing the industry for many years and actively researches and develops. This creation was born early; therefore, it mainly uses the ratchet drive head to its end. The outer peripheral contour is set to be polygonal in shape for connecting an auxiliary collar having a magnetic ring, and is used to cooperate with the original hidden magnetic member to enhance the adsorption of the screwdriver head on the upper and lower sides of the screwdriver. Insertion strength, at the same time, due to the conduction of magnetic force, The screw workpiece can be firmly clamped together, which is beneficial to the smooth operation of the screwing operation. In particular, the collar can be quickly rotated to accelerate the swirling efficiency, and the utility model can effectively improve the practical value and the convenience of operation. For the purpose of creating the most important creations.

Therefore, the present invention refers to a medium-sized ratchet wrench structure in which a wrench body has a ratchet drive head at one end, and a control knob is used to control the direction of action of the ratchet assembly, and the main purpose is to actuate the lower end of the ratchet drive head. The outer circumference is formed into a polygonal shape, and the collar is inserted into a collar having a corresponding polygonal sleeve hole, and the other end of the collar is provided with a through hole, and a magnetic ring member is fixed to the inner edge of the through hole.

In order to further understand the technical means and structural features of this creation, it is detailed with some drawings: please refer to the figures shown in the first, second, third, fourth and fifth figures. The figure shows that the main body of the wrench 20 has a ratchet driving head 21 at one end, and controls the direction of action of the ratchet assembly by a steering knob 22, which mainly makes the outer periphery of the working end 23 below the ratchet driving head 21 into a polygonal shape, and has a plug-in type Corresponding to the collar 30 of the polygonal sleeve hole 31, the other end of the collar 30 is provided with a through hole 32, and a magnetic ring member 33 is fixed to the inner edge of the through hole 32.

By the design of the above structure, as shown in the third, fourth and fifth figures, the hidden magnetic member 24 disposed inside the working end 23 and the magnetic ring member 33 located at the lower edge of the collar 30 will be capable of The collar 30 is stably adsorbed by the magnetic member 24, and then the magnetic head 24 and the magnetic ring member 33 are sequentially sucked by the magnetic head member 24 and the magnetic ring member 33, respectively, in such a manner that the ring ring is correspondingly and pulled. It will be able to achieve the best possible insertion strength without being easily disengaged.

Moreover, as mentioned above, such articles are intended to be held by the palm of the hand, and the ratchet drive head 21 will be slightly exposed outside the palm of the hand. Therefore, when the user uses the creation, it will be able to use the thumb. And the index finger turns the collar 30 to make it rotate quickly (as shown in the sixth figure), thereby obtaining an excellent additional effect of accelerating the screwing operation. Of course, this operation is mainly used for the screw that does not require too much force. The middle of the operation.

Of course, since the ratchet assembly including the ratchet drive head 21 and the steering knob 22 is a well-known and widely used hand tool having a set of accessories, the basic steering operation principle is believed to be familiar to the world, and sincere. The characteristics that should not be included in this creation are not included in the creator, so please check.

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.
