Description

Extension sleeve

The present invention relates to a socket wrench, and in particular to an extended socket, which can be observed from the outside to know the exact position of the nut for screwing action.

The socket wrench is the most convenient, flexible and safe hand tool for removing bolts and nuts. The socket wrench set is composed of multiple socket parts with hexagonal holes, matching extension rods, handles and other accessories. It is used with handles or power tools. The socket part is a cylinder with a concave hexagonal hole, which can be inserted into a hexagonal nut or bolt head. The extension rod connects the socket part or can be an integral structure with the socket part. The socket part with a longer extension rod is also called a socket part. Long sleeves, in narrow or deeply recessed spaces, can only be extended by using an extension sleeve to reach into the space, and then by turning the handle or starting the power tool to rotate the extension sleeve, and then screw the nut or bolt head to achieve the function of screwing or removing the nut or bolt; However, for the screwing action of the nut, because the extension sleeve is in the shape of a long tube, it is impossible to see the inside clearly, and there is no way to know where the nut is actually screwed to, whether to continue to operate the handle or let the power tool continue to start? The user can only evaluate how long the operation takes, roughly estimate the rough position, or feel that the resistance seems to be getting bigger and the fast lock is all the way, should it be stopped? Or should it continue? …resulting in frequent pauses during the operation, leading to problems such as unsmooth work and prolonged working hours.

The main purpose of the invention is to provide an extended sleeve that can observe the exact position of the nut from the outside, so that the operation can be carried out smoothly and the working time can be shortened.

Figure 5 is a schematic plan view of a cross-section of an extended sleeve in a preferred embodiment of the present invention.

Please refer to Figures 1 and 2, which show an extended sleeve 100 provided by a preferred embodiment of the present invention. The extended sleeve 100 is a hollow tubular body as a whole, including: an actuating portion 10, a sleeve portion 20, a body portion 30, and a marking assembly 40.

The actuating part 10 is disposed at one end of the extension sleeve 100 and is a hexagonal rod for connecting with a driving tool 200. The driving tool 200 may be a pneumatic tool gun. The driving tool 200 is connected with the actuating part 10 and is used to transmit power.

The sleeve portion 20 is disposed at the other end of the extended sleeve 100 and has an inner polygonal sleeve hole 21. In the embodiment of this specification, the inner polygonal sleeve hole 21 is an inner hexagonal sleeve hole for a nut 300 to be inserted and installed. The nut 300 is a hexagonal nut. Of course, it can also be correspondingly configured as an inner quadrangular sleeve hole (not shown) for a quadrangular nut to be inserted and installed.

The body 30 has an appropriate length and is used to connect the actuating portion 10 and the sleeve portion 20. A central through hole 31 is provided at the center of the body 30, and the central through hole 31 is connected to the inner polygonal sleeve hole 21. In addition, a long through slot 32 is provided in the axial direction of the outer periphery of the body 30, and the long through slot 32 passes through the central through hole 31. A size scale is marked on at least one side of the long through slot 32, and the size scale is displayed correspondingly through the position of the marking component 40; in the embodiment of this specification, a metric size scale 33 is marked on one side of the long through slot 32, and an imperial size scale 34 is marked on the other side of the long through slot 32.

The marking assembly 40 extends from the radial direction of the body 30 into the long through slot 32 and is arranged on the body 30. The marking assembly 40 can be pushed and displaced along the long through slot 32. The marking assembly 40 includes an outer ring 41 and a stop rod 42. The outer ring 41 is a ring and is displaceably sleeved on the outer periphery of the body 30. A set hole 411 is penetrated in the radial direction of the outer ring 41. The set hole 411 is provided with an internal thread 412. The set hole 411 corresponds to the long through slot 32. The stop rod 42 is a round rod, one end of which has an enlarged head 421 and the other end has a spherical tail 422. A section is provided between the enlarged head 421 and the spherical tail 422. The outer threaded portion 423 is adjacent to the enlarged head portion 421, and the outer threaded portion 423 can be threaded with the inner thread 412 of the assembly hole 411. The stop rod 42 radially passes through the assembly hole 411 of the outer ring 41, the long through groove 32 of the body 30, and extends into the central through hole 31. The expansion of the stop rod 42 The large head portion 421 is hexagonal and exposed outside the outer ring 41. The outer thread portion 423 is screwed with the inner thread 412 of the assembly hole 411. The spherical tail portion 422 abuts against the inner wall of the body 30. The stop rod 42 penetrates and pivots the outer ring 41 on the body, and the stop rod 42 and the outer ring 41 are linked and displaced together.

Please refer to FIGS. 3 and 4. Before the nut 300 is screwed onto a screw rod 400, the length of the screw rod 400 can be measured by the metric size scale 33 or the imperial size scale 34 on the body 30 of the extended sleeve 100 of the present invention. The length of the screw rod 400 can be known by manually pushing the marking assembly 40. When the nut 300 is screwed onto the screw rod 400, the nut 300 is placed in the inner polygonal sleeve hole 21 of the sleeve portion 20, and the screw rod 400 is aligned with the inner polygonal sleeve hole 21 of the sleeve portion 20. When the driving tool 200 is connected to the actuating portion 10 and started, the entire extension sleeve 100 of the present invention is driven to rotate, and the nut 300 disposed in the inner polygonal sleeve hole 21 of the sleeve portion 20 is driven to rotate and shift relative to the screw rod 400. At this time, the end of the screw rod 400 extends into the inner polygonal sleeve hole 21 of the sleeve portion 20, the central through hole 31 of the body portion 30, and contacts the stop rod 42 of the marking assembly 40 (please refer to FIG. 5). When the driving tool 200 continues to drive the nut 300 so that the nut 300 is screwed on the screw rod 400, the end of the screw rod 400 extends into the inner polygonal sleeve hole 21 of the sleeve portion 20, the central through hole 31 of the body portion 30, and contacts the stop rod 42 of the marking assembly 40 (please refer to FIG. 5). As the length of the rod 400 becomes longer and longer, the screw rod 400 continues to push the stop rod 42 to move along the long through slot 32. The stop rod 42 passes through the outer ring 41, and the stop rod 42 moves together with the outer ring 41. Therefore, through the position display of the outer ring 41, it is clear that the current relative position of the nut 300 screwed on the screw rod 400 can be clearly known; that is, assuming that the nut 300 is originally measured to be screwed to the position of 8.5 cm of the length of the screw rod 400, and at this time, the position mark of the outer ring 41 is located at 4.5 cm (as shown in Figure 3), then it can be Knowing that the nut 300 is currently screwed to the 4.5 cm position of the screw rod 400, the driving tool 200 should continue to move until the position mark of the outer ring 41 is located at 8.5 cm (as shown in Figure 4), which means that the screwing action of the nut 300 has been completed and the driving tool 200 should be stopped. Therefore, the extended sleeve 100 of the present invention can observe the exact position of the nut relative to the screw rod from the outside, and there is no need to frequently pause the action during the operation, so that the action of operating the nut can be carried out smoothly, and the working time can be shortened to achieve the expected creative purpose.

The above embodiments are only for illustrative purposes to illustrate the technology and its effects of the present invention, and are not intended to limit the present invention. Anyone skilled in the art can modify and change the above embodiments without violating the technical principles and spirit of the present invention. Therefore, the scope of protection of the present invention shall be as described below in the scope of the patent application.
