Description

Torque tool quick release device

The invention relates to a quick release device for torque tools.

Generally, when performing locking operations, hand tools are used to lock the fasteners to achieve a labor-saving effect, such as using a socket wrench to loosen/tighten bolts, nuts, etc.; or, depending on the parts to be driven, use the hand tools to lock the fasteners. A socket of the tool is replaceably connected to a driving tool head. Among them, in order to keep the driving parts such as bolts and nuts stable and not falling off in the sleeve, or to keep the driving tool head stable and not falling off in the socket, additional magnetic parts can also be provided in the sleeve or socket.

In addition, in order to facilitate the removal of the driving tool head from the socket after operation or during replacement, there is also a structure that can move relative to the socket and push the driving tool head. However, in conventional tools, multiple components need to be separately provided or/and processed with matching corresponding structures, resulting in complex components, difficulty in processing, manufacturing, and assembly, poor manufacturing efficiency, and high cost.

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

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

In order to achieve the above object, the present invention provides a torque tool quick release device, which includes: a body, including a receiving hole, a connecting hole for assembling a driven component, and a connecting hole connected between the receiving hole and the connecting hole. A through hole, the receiving hole and the connecting hole are respectively open on two opposite sides of the body, and the diameter of the through hole is smaller than the receiving hole and the connecting hole; a push rod can relatively movably extend through the through hole. To the connecting hole, an end portion of the push rod located in the connecting hole is provided with a setting hole, the end portion has a radial size larger than the diameter of the through hole; and a magnetic component is fixed in the setting hole.

The following examples are only used to illustrate the possible implementation modes of the present invention, but are not intended to limit the scope of protection of the present invention.

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 component 30 .

The body 10 includes a receiving hole 11 , a connecting hole 12 for assembling a driven component 100 (such as a tool head, a rod or similar objects), and a connecting hole 11 connected between the connecting hole 12 and the connecting hole 12 . The through hole 13, the receiving hole 11 and the connecting hole 12 are respectively open on two opposite sides of the body 10, and the diameter of the through hole 13 is smaller than that of the receiving hole 11 and the connecting hole 12; the push rod 20 can be relatively movably extended. Passing through the through hole 13 to the connecting hole 12, in detail, the push rod 20 includes a head 21 received in the hole 11 and a body 22, the body 22 extends from the head 21 through The through hole 13 reaches the connecting hole 12. An end portion 221 of the body 22 located in the connecting hole 12 is provided with a setting hole 222. The end portion 221 has a radial size greater than the diameter of the through hole 13 ( 5), whereby the end portion 221 cannot pass upward through the through hole 13 to limit the push rod 20; the magnetic component 30 is fixed in the setting hole 222. Thereby, the components, manufacture and assembly of the torque tool quick release device 1 are simple and fast, greatly improving production efficiency and reducing costs. In addition, by pressing the push rod 20, the driven part 100 can be quickly moved from the connecting hole 12 toward the Push it outward (Fig. 7) to facilitate taking out the driven part 100.

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

Preferably, the head 21 curves beyond the hole 11 to conveniently 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 conical coil spring set on the body 22 . The body 10 further includes a spacer 17 extending radially between the hole 11 and the connection hole 12 , the through hole 13 is provided in the spacer 17 , and the elastic member 40 is provided in the head 21 and the spacer. Between Department 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 expands outward, a circular hole section 224 that communicates with the first tapered hole section 223 and extends inward, and a circular hole section 224 that communicates with the circular hole section 224 and that tapers inward. The second tapered hole section 225. The first tapered hole section 223 facilitates the introduction of the magnetic component 30; the round hole section 224 can stably maintain and fix the magnetic component 30; and the second tapered hole section 225 facilitates the insertion of the magnetic component 30 into the setting hole 222. The stress dispersion and deformation margin of the end portion 221 are beneficial to the expansion of the end portion 221 and prevent the end portion 221 from being damaged. The magnetic component 30 extends beyond the installation hole 222 and has a better effect of magnetically attracting the driven component 100 . In this embodiment, the rigidity of the magnetic member 30 is greater than the rigidity of the end portion 221. The magnetic member 30 presses the end portion 221 into the setting hole 222 in a radial extrusion and expansion manner, whereby the magnetic member 30 can be set when the magnetic member is set. At the same time, the end portion 221 is radially expanded to have a radial size larger than the diameter of the through hole 13 , which is very simple and fast. However, the radial size of the end portion 221 can also be expanded first, and then the magnetic component 30 is placed in the setting hole 222 . Here, the rigidity of the magnetic component 30 can be no greater than the rigidity of the end portion 221 .

In other possible embodiments, as shown in FIG. 9 , 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 component 30 . For example, the sleeve 50 can be made of copper or other suitable metal or non-metal materials; the rigidity of the sleeve 50 is preferably smaller than the rigidity of the end portion 221 or/and the magnetic component 30, so that the sleeve 50 can be slightly deformed to tighten. The magnetic component 30 is fixed with a sleeve, and the installation is simple and stable.
