Description

Multifunctional ratchet wrench structure

This creation is about a multi-purpose ratchet wrench structure, especially a ratchet wrench that can be adjusted and changed at different angles.

Regarding the locking or loosening of a fixing member such as a screw, it is generally operated by a hand tool such as a ratchet wrench. The ratchet wrench typically includes a tool head and a handle for the user to hold, and one end of the handle is coupled to the tool head such that torque applied by the user to the handle can be transmitted to the tool head. Again, the handle is typically configured to pivot relative to the tool head to allow the user to change the angle of the handle relative to the tool head as needed for the operating environment. Specifically, the handle can be 180° relative to the tool head such that the ratchet wrench is linear or can be at 90° relative to the tool head such that the hand tool has an L-shaped profile.

A ratchet wrench that can form different angles with respect to the tool head is advantageous in operation. However, when the operation mode of the ratchet wrench is 90° with respect to the tool head, the process of the user holding the handle about the axial direction perpendicular to the tool head often occurs. The lack of comfort in the position of the hand and the wrist makes the operational flexibility negatively affected. Therefore, for different angles of rotation, it is generally necessary to use different hand tools.

It is an object of the present invention to provide a multi-function ratchet wrench structure that can improve the above problems. The ratchet wrench structure allows a user to use a tool head with a 90°, 180° or other angle of operation mode relative to the handle. The rod is combined with the handle to selectively change the operating angle for comfortable and labor-saving operation.

The multifunctional ratchet wrench structure according to the present invention comprises a handle, a tool bar and a rod body. The front end of the handle has two spaced joints and a pivoting hole extending through the two joints. The handle is provided with a through hole. The joint has a through hole therebetween, and the through hole communicates with the through hole. A first steel ball, a second steel ball and an elastic element positioned between the two steel balls are received in the through hole, and the first steel ball and the second steel ball protrude from the open end of the through hole. One end of the tool head is pivotally connected between the two joints of the handle and the end has a ratchet portion that abuts the second steel ball. The rod body can be inserted into the perforation of the handle to abut the first steel ball, and the rod body can be a 90-degree crossing force bar with respect to the handle.

In one embodiment, the rear end of the handle has a coupling hole between the through hole and the coupling hole and communicate with each other, and the rod body can be inserted into the coupling hole to extend the length of the handle.

Preferably, the front end of the rod body is a square body, and the joint hole of the handle is square.

Other objects, advantages and features of the present invention will become apparent from

The preferred structural content of the present invention will be described as an example only, but not by way of limitation, with reference to the accompanying drawings. Referring to the first to seventh figures, the multifunctional ratchet wrench of the present invention comprises a handle 1. A tool head 2 and a rod 8. The front end of the handle 1 has two spaced joint portions 11 and a pivot hole 12 extending through the two joint portions 11. The center of the handle 1 has a longitudinally extending through hole 13 between the joint portion 11 and the through hole 13 and a through hole 14 extending in the lateral direction. At the rear end of the handle 1, there is a one-piece coupling hole 15. The through hole 13 is located between the through hole 14 and the coupling hole 15 and communicates with each other. The through hole 14 houses a first steel ball 4, a second steel ball 5, and an elastic member 6 located between the two steel balls 4, 5. The apertures of the two open ends of the through hole 14 are reduced to make the first steel ball 4 and The second steel ball 5 can partially protrude from the two open ends of the through hole 14.

One end of the tool head 2 is pivotally connected between the two joint portions 11 of the handle 1 and has a ratchet portion 21 at the end, the center of the ratchet portion 21 has a shaft hole 22 therethrough, and the other end of the tool head 2 has a ratchet head 3. . The ratchet portion 21 of the tool head 2 is placed between the two joint portions 11 of the handle 1 and the shaft hole 22 of the tool head 2 is aligned with the pivot hole 12 of the handle 1, and is pivoted through the shaft hole 22 by a fixing member 7. The hole 12 joins the tool head 2 with the handle 1 such that the ratchet portion 21 of the tool head 2 abuts against the second steel ball 5.

One of the front ends 81 of the rod 8 is a square body and one of the front ends 81 is provided with a floating steel ball 82. The rod 8 can be inserted into the perforation 13 of the handle 1 to engage the handle 1 at 90 degrees. At this time, the tool head 2 and the ratchet head 3 can be displayed at different angles with respect to the handle 1 for operation (see the sixth figure), and the rod body 8 can be used as a force-applying mast to save the screwing or loosening. The strength of the workpiece. Moreover, the rod 8 abuts against the first steel ball 4, so that the elastic member 6 in the through hole 14 pushes the second steel ball 5 to increase the engaging force of the handle 1 and the tool head 2. In addition, the front end 81 of the rod 8 can be inserted into the coupling hole 15 of the handle 1 to extend the length of the handle 1 (see the seventh figure), so as to reduce the tightening or rotation in use according to the length limitation caused by different environments. The force exerted by the loose workpiece.

The effect achieved by this creation is:

1. The second steel ball 5 is pressed by the elastic force of the elastic member 6 to engage with the ratchet portion 21 of the tool head 2, so that the tool head 2 can be arbitrarily and arbitrarily changed the operating angle.

2. When the direction of the force application is to be changed, the rod body 8 can be inserted into the through hole 13 of the handle 1, so that the first steel ball 4 and the second steel ball 5 are simultaneously pressed by the ratchet portion 21, the rod body 8 and the elastic member 6. In order to stabilize the ratchet portion 21 of the tool head 2 and the second steel ball 5, it does not cause an accident of changing the angle when the workpiece is screwed or unscrewed.

Third, the use of the handle 1, the tool head 2, the ratchet head 3, and the angle formed by the rod body 8 can overcome various working environments and dead angles, and will not be interrupted by the influence of the working environment.

4. The rod 8 is inserted into the through hole 13 of the handle 1 or the coupling hole 15 as a fixed end or a lever end, which can save the force of tightening or unscrewing the workpiece.

The foregoing is a description of the preferred embodiments of the present invention, and various changes or modifications may be made in the spirit of the invention. Therefore, obvious substitutions and modifications to those skilled in the art will still be incorporated in the scope of the patent claimed herein.
