Description

Torque tool quick release

This creation is about a quick release device of a torque tool.

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

In addition, in order to facilitate the removal of the driving tool head in the socket after operation or during replacement, a structure that can move relatively in the socket to push the driving tool head is provided. However, in the conventional tools, corresponding structures need to be separately provided or/and processed on multiple components, resulting in complex components, difficult 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-mentioned problems.

The main purpose of this creation is to provide a quick release device for torque tools. Its components, manufacture and assembly are simple and fast, greatly improving production efficiency and reducing costs, and can quickly push the driven parts outward for easy removal.

In order to achieve the above purpose, this creation provides a quick release device for torque tools, including: a body, including a hole, a connecting hole for assembling a driven part, and a connection between the containing hole and the connecting hole The through hole, the receiving hole and the connecting hole are respectively opened on the opposite sides of the body, the through hole has a smaller diameter than the receiving hole and the connecting hole; a push rod can be relatively movably extended through the through hole and To the connecting hole, one end of the push rod located in the connecting hole is provided with a setting hole, the end has a radial dimension larger than the diameter of the through hole; and a magnetic piece is fixed in the setting hole.

The following examples are only used to illustrate the possible implementation of this creation, but it is not intended to limit the scope of protection of this creation, and it will be described first.

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

The body 10 includes a receiving hole 11, a connecting hole 12 for assembling a driven part 100 (such as a tool bit, a connecting rod or the like), and a connection between the receiving hole 11 and the connecting hole 12. Through hole 13, the receiving hole 11 and the connecting hole 12 are respectively opened on 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 extended relatively movable Through the through hole 13 to the connecting hole 12, in detail, the push rod 20 includes a head 21 accommodated in the cavity 11 and a body 22, the body 22 extends from the head 21 through The through hole 13 reaches the connection hole 12, and the body portion 22 is located at a terminal portion 221 of the connection hole 12 to be provided with a setting hole 222, and the terminal portion 221 has a radial dimension greater than the aperture of the through hole 13 ( FIG. 5 ), whereby the end portion 221 cannot pass upward through the through hole 13 to limit the push rod 20 ; the magnetic element 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 to the Pushing outward ( FIG. 7 ), it is convenient to take out the driven part 100 .

In this embodiment, the torque tool quick release device 1 is a driving tool (such as a ratchet wrench, socket wrench or similar tools) with a driving head at one end, and the body 10 further includes a handle 14 and a relatively rotatable The cylinder part 15 combined with the handle 14 is inserted, and the cylinder part 15 is provided with the accommodation hole 11 , the connection hole 12 and the through hole 13 . Wherein, the cylinder member 15 is combined with the handle 14 in a one-way ratchet manner, preferably, the direction of the one-way ratchet movement can be switched through a switching mechanism 16 of the torque tool quick release device 1, so that the cylinder The component 15 can be used to drive the driven component 100 forward and reverse.

Preferably, the head 21 protrudes beyond the receiving hole 11 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 conical coil spring set on the body 22 . The main body 10 further includes a spacer 17 radially extending between the receiving hole 11 and the connecting hole 12, the through hole 13 is set in the spacer 17, and the elastic member 40 is set in the head 21 and the spacer. Section 17 between. Thereby, the push rod 20 can be reset automatically through the action of the elastic member 40 after the push rod 20 is pressed.

The setting hole 222 includes a first tapered hole section 223 that gradually 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 tapers inward. The second cone section 225. The first tapered hole section 223 facilitates the introduction of the magnetic piece 30; the round hole section 224 can keep the magnetic piece 30 stably fixed; the second tapered hole section 225 provides the magnetic piece 30 to be inserted into the setting hole 222 process 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. Wherein, the magnetic part 30 protrudes beyond the setting hole 222 and has a better effect of magnetically attracting the driven part 100 . In this embodiment, the rigidity of the magnetic piece 30 is greater than the rigidity of the end portion 221, and the magnetic piece 30 presses the end portion 221 into the installation hole 222 in a radially expanding manner. At the same time, expanding the end portion 221 radially to have a radial dimension larger than the diameter of the through hole 13 is very simple and fast. However, the radial dimension of the end portion 221 can also be expanded first, and then the magnetic piece 30 is placed in the installation hole 222 , where the rigidity of the magnetic piece 30 may not be greater than that of the end portion 221 .

In other possible embodiments, as shown in FIG. 10 , the torque tool quick release device may further include a sleeve 50 , the sleeve 50 is fixed in the installation hole 222 and sleeved on the magnet 30 . For example, the sleeve 50 can be made of copper or other suitable metal or non-metallic materials; the rigidity of the sleeve 50 is preferably less than that of the end portion 221 or/and the magnet 30, so that the sleeve 50 can be slightly deformed to tighten The sleeve fixes the magnetic part 30, and the installation is simple and stable.
