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; a magnetic ring is fixed in the through hole; and a push rod can be relatively movably extended and inserted in the through hole and the through hole magnetic ring.

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 magnetic ring 30 .

The through hole 13, the receiving hole 11 and the connecting hole 12 are respectively opened on the opposite sides of the body 10; the push rod 20 can be relatively movably extended through the through hole 13 and the magnetic ring 30, in detail, the push rod The rod 20 includes a head 21 and a body 22 accommodated in the cavity 11, the body 22 extends from the head 21 and is inserted in the through hole 13 and the magnetic ring 30; the magnetic ring 30 is fixed on the through hole 13. 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 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. Wherein, one end surface 23 of the push rod 20 can be retracted into the magnetic ring 30 to prevent the driven part 100 from being blocked to affect the magnetic attraction effect and cause unstable insertion.

Preferably, the body 10 further includes a first flange 18 arranged along the edge of the receiving hole 11 and extending radially inward, the head 21 can be axially stopped by the first flange 18, and can be Make sure that the push rod 20 does not escape from the receiving hole 11 .

In this embodiment, the through hole 13 includes a small-diameter section 131 communicating with the receiving hole 11 and a large-diameter section 132 communicating with the connecting hole 12, the magnetic ring 30 is fixed on the large-diameter section 132; the magnetic ring 30 includes two taper openings 31 that gradually expand and open outwards on two opposite sides, and one of the taper openings 31 facing the small-diameter section 131 is larger in diameter than the small-diameter section 131 . The tapered opening 31 is beneficial to the introduction of the push rod 20 , and the push rod 20 will not touch the fragile corner edge of the magnetic ring 30 during operation, which can prevent the push rod 20 from damaging the magnetic ring 30 .

In this embodiment, a ring gap G is formed between one side ring surface 32 of the magnetic ring 30 and the spacer portion 17 (which may have a ring slope) of the main body 10, and the ring gap G is gradually expanded radially inwards. This magnetic ring 30 has a margin and is not easy to be damaged when it is set; the magnetic ring 30 is preferably not beyond the through hole 13 and does not extend into the connecting hole 12. A small distance can be kept between them to prevent the driven part 100 from directly contacting the magnetic ring 30, so as to protect the magnetic ring 30 from being damaged.
