Description

Torque Tool Quick Release

The present invention relates to a quick release device for a torque tool.

Generally, when performing locking operations, hand tools are used to lock the locking parts to achieve a labor-saving effect, such as using a socket wrench to loosen/tighten bolts and nuts, etc.; or, according to different driven parts, a driving tool head can be replaceably connected to a socket of the hand tool. In order to keep the bolts, nuts and other driving parts stable in the socket and not fall off, or to keep the driving tool head stable in the socket and not fall off, a magnetic part can also be set in the socket or the socket.

In addition, in order to facilitate the removal of the driving tool head from the socket after operation or when replacing, a structure that can move relatively in the socket and push the driving tool head is also provided. However, in conventional tools, it is necessary to separately provide or/and process matching structures on multiple components, resulting in complex components, difficulty in processing, manufacturing, and assembly, poor manufacturing efficiency, and high costs.

Therefore, it is necessary to provide a novel and advanced torque tool quick release device to solve the above-mentioned problems.

The main purpose of the present invention is to provide a torque tool quick release device, which has simple components, manufacturing and assembly, greatly improves production efficiency and reduces costs, and can quickly push the driven part outward for easy removal.

To achieve the above-mentioned purpose, the present invention provides a torque tool quick-release device, comprising: a main body, including a receiving hole, a connecting hole for assembling a driven part, and a through hole connecting the receiving hole and the connecting hole, the receiving hole and the connecting hole are respectively opened on two opposite sides of the main body, and the diameter of the through hole is smaller than that of the receiving hole and the connecting hole; a push rod, which can be relatively movably extended through the through hole to the connecting hole, and a setting hole is provided at one end of the push rod located in the connecting hole, and the end has a radial dimension larger than the diameter of the through hole; and a magnetic member fixed in the setting hole.

The following examples are merely used to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention, so it should be noted in advance.

Please refer to FIGS. 1 to 8 , which show a preferred embodiment of the present invention. The torque tool quick release device 1 of the present invention includes a body 10 , a push rod 20 and a magnetic member 30 .

The body 10 includes a receiving hole 11, a connecting hole 12 for assembling a driven member 100 (such as a tool head, a connecting rod or the like), and a through hole 13 connecting the receiving hole 11 and the connecting hole 12. The receiving hole 11 and the connecting hole 12 are respectively opened at two opposite sides of the body 10. The through hole 13 has a smaller diameter than the receiving hole 11 and the connecting hole 12. The push rod 20 can be relatively movably extended through the through hole 13 to the connecting hole 12. In detail, the push rod 20 includes A head portion 21 and a body portion 22 are accommodated in the receiving hole 11. The body portion 22 extends from the head portion 21 through the through hole 13 to the connecting hole 12. A terminal portion 221 of the body portion 22 located in the connecting hole 12 is provided with a setting hole 222. The terminal portion 221 has a radial dimension greater than the diameter of the through hole 13 (FIG. 5), so that the terminal portion 221 cannot pass through the through hole 13 upwards to limit the push rod 20; the magnetic member 30 is fixed in the setting hole 222. Thus, the components, manufacturing and assembly of the torque tool quick release device 1 are simple and fast, which greatly improves production efficiency and reduces costs. In addition, by pressing the push rod 20, the driven part 100 can be quickly pushed outward from the connecting hole 12 (FIG. 7), so that the driven part 100 can be easily removed.

In this embodiment, the torque tool quick release device 1 is a driving tool (such as a ratchet wrench, a socket wrench or a similar tool) having a driving head at one end, and the body 10 further includes a handle 14 and a cylinder 15 that is relatively rotatably inserted and coupled to the handle 14, and the cylinder 15 is provided with the receiving hole 11, the connecting hole 12 and the through hole 13. The cylinder 15 is coupled to the handle 14 in a unidirectional ratcheting manner. Preferably, the direction of the unidirectional ratcheting can be switched through a switching mechanism 16 of the torque tool quick release device 1, so that the cylinder 15 can drive the driven member 100 in forward and reverse directions.

Preferably, the head 21 is arc-convex beyond the receiving hole 11, so as to facilitate and effectively press and push the push rod 20. The torque tool quick release device 1 further includes an elastic member 40, which is a set of conical coil springs arranged on the body 22. The body 10 further includes a spacer 17 extending radially between the receiving hole 11 and the connecting hole 12, the through hole 13 is arranged in the spacer 17, and the elastic member 40 is arranged between the head 21 and the spacer 17. Thereby, after the push rod 20 is pressed, the push rod 20 can be automatically reset through the action of the elastic member 40.

The setting hole 222 includes a first tapered hole section 223 that gradually expands outward, a circular hole section 224 that is connected to the first tapered hole section 223 and extends inward, and a second tapered hole section 225 that is connected to the circular hole section 224 and gradually contracts inward. The first tapered hole section 223 is conducive to the introduction of the magnetic component 30; the circular hole section 224 can stably hold and fix the magnetic component 30; the second tapered hole section 225 provides stress dispersion and deformation margin for the terminal portion 221 during the process of the magnetic component 30 being placed in the setting hole 222, which is conducive to the expansion of the terminal portion 221 and prevents the terminal portion 221 from being damaged. Among them, the magnetic component 30 exceeds the setting hole 222, which has a better effect of magnetically attracting the driven component 100. In this embodiment, the rigidity of the magnetic component 30 is greater than that of the terminal portion 221, and the magnetic component 30 radially squeezes and expands the terminal portion 221 into the setting hole 222, so that the terminal portion 221 can be radially expanded to have a radial dimension greater than the diameter of the through hole 13 while the magnetic component 30 is being set, which is very simple and fast. However, the radial dimension of the terminal portion 221 can also be expanded first, and then the magnetic component 30 is placed in the setting hole 222, in which case the rigidity of the magnetic component 30 may not be greater than that of the terminal portion 221.

In other possible embodiments, as shown in FIG. 10 , the torque tool quick release device may further include a set 50, which is fixed in the setting hole 222 and sleeved on the magnetic member 30. For example, the set 50 may be made of copper or other appropriate metal or non-metal material; the rigidity of the set 50 is preferably less than the rigidity of the end portion 221 and/or the magnetic member 30, so that the set 50 can be slightly deformed to tightly sleeve and fix the magnetic member 30, and the installation is simple and stable.
