Description

Insulating tool device

The invention relates to a device for insulating tools, in particular to the technical field of hand tools, for limiting the offset of the wrench drive member, so as to achieve the benefit of extending the service life of the wrench.

The advancement of modern industrialization, the assembly and maintenance of various machinery depend on hand tools. Even though there are automatic assembly machines, hand tools are still an indispensable tool for more precise assembly and maintenance.

There are a wide variety of hand tools, including a word screwdriver, a ratchet wrench, a cross screwdriver, etc., various hand tools designed for the size and type of different screws (such as bolts, screws, nuts, etc.), in which the ratchet wrench is an evolution of the wrench. In order to control the operating wrench in one direction, the ratchet body is provided with a ratchet ring inside the wrench body, and the wrench body is provided with a driving component that is received in the ratchet ring and is connected with the ratchet. The ratchet ring is provided with a set of joints, which can be assembled with the sleeve, and the ratchet set is used to control the direction of rotation of the ratchet ring, and the sleeve and the screw are engaged to lock and loosen the screw. .

In general, the wrench tool is made of metal for its sturdy structure, and the metal material is made of conductive material. If it is repaired or assembled by electrical machinery, it works in a current environment. If it is accidentally leaked, it is easy to conduct by wrench. Current is supplied to the user, causing the user to be shocked, shocked, burned, and even more serious, even fatal. Therefore, some manufacturers have developed an insulated wrench tool that covers the wrench with an insulating material to prevent current conduction.

However, the end of the ratchet wrench driver needs to be exposed outside the insulating material to lock and loosen the screw. Therefore, the end of the driving member of the insulating wrench has a certain distance from the wrench body, so the driving member of the insulating wrench has a longer length than the general ratchet. The length of the driver of the wrench is long. Therefore, the driving member is offset and shaken during the operation, which causes the ratchet teeth of the ratchet group and the ratchet ring to wear heavily, so that the ratchet is stuck and cannot smoothly pass the ratchet. In the ring, the operation of the wrench is not smooth, and the service life of the ratchet wrench is shortened. Therefore, it is necessary to develop an "insulation tool device" that prevents the drive member from shifting.

SUMMARY OF THE INVENTION The main object of the present invention is to provide an "insulation tool device" which can improve the driving member of a conventional insulating tool, resulting in a high stability of the driving member during the operation of the insulating tool, which is easy to be offset and shaken, and thus the internal ratchet The ring tooth and the ratchet wear are severe, which causes the ratchet to be stuck and cannot smoothly advance and retreat, so that the ratchet wrench consumes a high rate of replacement.

In order to achieve the above objects and effects, the device for insulating tools of the present invention comprises a wrench body, a ratchet set, a driving member, a sleeve and an insulating sheath, wherein: the wrench body head is provided with a ratchet ring The ratchet assembly is disposed in the ratchet ring and is in mesh with the ratchet ring; the driving member passes through the ratchet ring, and one end of the driving member is provided with a steering portion that abuts the ratchet set, the driving member The other end is provided with a set of joints, and the driving member is provided with a connecting portion connecting the guiding portion and the fitting portion; the sleeve is provided with a set of perforations for the driving member, and the ratchet is closed by the sleeve And the insulating portion covers the wrench body, and the insulating sheath forms an insulating ring on the sleeve body toward the sleeve portion, the inner wall of the insulating ring and the driving There is a space between the pieces, and the fitting portion protrudes outside the insulating ring.

Further technical features of the invention include the following:

(1) The wrench body is provided with a first-order portion corresponding to one end of the kit, and the kit is assembled with the step.

(2) The kit is provided with a body, the piece is disposed in the step and engages with the inner wall of the joint, the piece closes the ratchet set and the guiding portion in the head of the wrench body, and the end of the piece A limiting ring is protruded, and the through hole extends through the sheet body and the limiting ring, and the limiting ring surrounds the circumferential side of the connecting portion.

(3) a locking hole is arranged in the step, the piece body is provided with a pair of locking holes which should be locked, and the piece body and the step are screwed through the locking hole and the locking hole is locked .

(4) The axial dimension of the limiting ring is proportional to the dimension of the connecting portion connecting the guiding portion to the end of the fitting portion by 1:6.

(5) The position of the end of the insulating ring is a joint between the connecting portion and the fitting portion.

In this way, the driving member is restricted by the hole wall of the through hole of the sleeve, so that the driving member is not arbitrarily offset, and the wear of the ratchet group is reduced, so that the wrench body has a stable structure for stable operation.

The invention is quite practical and innovative in the use of the "insulation tool device", and is worthy of promotion by the industry and publicized to the public.
