Description

A portable universal sleeve

technical field

The utility model relates to the technical field of hardware tools, in particular to a portable universal sleeve.

Background technique

When overhauling, repairing or installing equipment in substations, it is often encountered to remove various threaded screws, nuts or screws with other appearances. Existing tools for removing screws and nuts generally include cylinders or wrenches. Most of the cylinders are cylinders of fixed shape and size, and the corresponding cylinders must be found in each work to remove the corresponding screws and nuts. Workers often work at high places, and the space at the work site is limited, and they cannot carry too many cylinders. They can only climb up and down or rely on others to assist in delivery, which increases the danger to the work and reduces the work efficiency. The wrenches are roughly divided into two categories, one is a wrench with a fixed opening size, and the other is an adjustable wrench. Among them, wrenches of fixed open size must be prepared with wrenches of various specifications during working hours. When this type of wrench is working, it is necessary to constantly find and switch the wrench of the corresponding open size. The other type of adjustable wrench is more flexible and stronger, but the work encounters all kinds of wrenches. When the screws and nuts need to be removed, there should be enough twisting space beside the screws and nuts. If the space for the wrench to rotate is small, it is difficult to remove the screws and nuts. These two kinds of wrenches also seriously affect the work efficiency and the cumbersome process.

In view of the above problems, there is an urgent need for a tool with strong applicability in the maintenance of substation equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. In the following description, in order to clearly show the structure and working mode of the present invention, the drawings will be used as a reference to describe with the help of many directional words, but "front", "rear", "left" and "right" should be used for description. , "上", "下" and other words are understood as convenient terms, and should not be understood as limiting words.

The portable universal socket shown in Figure 1-2 includes a cylinder body 1, a pressing ring 8, a clamping jaw 4, a magnetic plug 5 and a trigger 7; the clamping jaws 4 are six, which are uniformly distributed on the cylinder body 1. On the outer edge of one end, a hexagonal arrangement is formed; the magnetic plug 5 is fixedly arranged on the other end of the cylinder 1, opposite to the clamping jaw 4; one end of the trigger 7 is provided with a slot for the magnetic plug 5 to be inserted and positioned (Fig. One end of the jaws 4 for clamping is called the front end, and the opposite end is called the rear end; there is a gap between the jaws 4, leaving space for the jaws 4 to gather and adjust ; On the outer wall at the rear end of the clamping jaw 4, along its length direction, wedge-shaped blocks 3 are all provided, the outer wall surface of the wedge-shaped block 3 is arc-shaped, and its tip is towards the rear end of the clamping jaws 4; Six clamping jaws 4 The outer wall of the wedge-shaped block 3 is provided with an external thread 6, the pressing ring 8 is sleeved on the wedge-shaped block 3 of the six clamping jaws 4, and the inner wall of the pressing ring 8 is provided with an internal thread that matches the external thread 6 (not shown in the figure). shown); the inner wall of the front end of the jaw 4 is a plane. When the pressing ring 8 is tightened and moves to the front end, the wedge-shaped block 3 has a certain slope, and the wedge-shaped block 3 is pressed and pushes the six clamping jaws 4 to swing toward the center, so that the hexagonal front end formed by the six clamping jaws 4 gradually shrinks , for the purpose of clamping screws and nuts. The connection between the clamping jaw 4 and the cylinder body 1 has a certain rigid deformation, and when the pressing ring 8 is screwed and moves to the rear end, the clamping jaw 4 swings and opens to the outside.

As a further improvement, the outer wall of the pressing ring 8 is provided with an anti-skid pattern 2, which increases the friction and facilitates the rotation of the pressing ring.

As a further improvement, the front end of the clamping jaw 4 is arc-shaped, which is convenient for quickly aligning and inserting screws and nuts.

In this embodiment, the cross-section of the magnetic plug 5 is a regular polygon, such as a regular pentagon, a regular hexagon, etc. Obviously, a suitable shape such as a pentagram can also be used.

As a preferred technical solution, the clamping jaws 4 and the cylinder body 1 are integrally formed as one piece, and obviously, they can also be separately manufactured and then connected together by welding or other means. The trigger 7 can be a ratchet trigger.

The working principle is as follows: put the cylinder body 1 on the nut and screw to be disassembled or installed, and tighten the pressure ring 8 to move to the front end, so that the front end of the six clamping jaws 4 gathers towards the clamped nut and screw and clamps the nut and screw. , connect the trigger 7 with the cylinder body 1 through the magnetic plug 5, and pull the trigger 7 to install or remove the nut and screw.

The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the within the scope of protection of the present invention.
