The utility model can be matched with multiple types of short-handle wrenches. The handle of the short-handle wrench is located in the rectangular slot hole, and the angle of the short-handle wrench is changed by pulling the sleeve, which increases the rotational torque of the short-handle wrench, and is convenient for use in Dismantling or installing nuts and flange spare parts of ceramic sanitary products in a small space improves labor efficiency and ensures maintenance quality.

Description

combination wrench

technical field

The utility model relates to a combined wrench, which is suitable for replacing nuts and flange spare parts of ceramic sanitary products.

Background technique

For maintenance work in the bathroom, kitchen, and bathroom, it is necessary to replace the nuts and flange spare parts of ceramic sanitary products. If you use ordinary pipe wrench and adjustable wrench, you will often encounter the following problems: 1. Due to the small space, ordinary tools are limited , Bring a lot of inconvenience to the maintenance work. 2. The flange nuts of ceramic sanitary products are mostly made of plastic or non-ferrous metals, and the use of ordinary tools can easily cause damage to the accessories. 3. The assembly and disassembly torque of ordinary tools is limited, and the rotation angle is also limited, resulting in loose nut flange fastening or difficult disassembly of the ceramic sanitary basin. 4. Due to the limitation of space, if an ordinary adjustable wrench is used, it is necessary to adjust the adjustable wrench repeatedly, and the function of the ordinary tool cannot be performed normally, which makes the maintenance work time-consuming and labor-intensive, and the labor efficiency is low.

Utility model content

The technical problem to be solved by the utility model is to provide a combined wrench, which can conveniently and quickly disassemble or install nuts and flange spare parts of ceramic sanitary products in a narrow space.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a combined wrench, which is characterized in that it includes a sleeve and a short handle wrench, and the outer circumference of the lower end of the sleeve is provided with an axial rectangular slot. The handle of the short handle wrench is located in the rectangular slot.

A further improvement of the utility model is that: the rectangular slots are symmetrically distributed on the outer circumference of the lower end of the sleeve. There are two pairs of rectangular slots.

The beneficial effect produced by adopting the above technical scheme is that the utility model can be matched with multiple types of short-handled wrenches. The rotation torque of the short handle wrench is increased, which facilitates the disassembly or installation of nuts and flange spare parts of ceramic sanitary products in a narrow space, improves labor efficiency and ensures maintenance quality.

Description of drawings

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

Fig. 1 is the structural representation of the utility model.

As shown in the picture: 1 sleeve, 2 rectangular slotted hole, 3 short handle wrench.

Detailed ways

In contrast to Fig. 1, the operation steps of the present utility model are further described:

Embodiment 1: A combined wrench, characterized in that it includes a sleeve 1 and a short handle wrench 3, the outer circumference of the lower end of the sleeve 1 is provided with an axial rectangular slot 2, the handle of the short handle wrench 3 The part is located in the rectangular slot 2.

The usage method of the present embodiment: common mechanical hands of different types can be cut off to become a short handle wrench 3 and a rectangular slotted hole 2 for matching. When the maintenance space is narrow, first select a suitable short-handle wrench 3 and clamp it on the nut of the ceramic sanitary product to be disassembled, then make the rectangular slot 2 at the lower end of the sleeve 1 fit over the handle of the short-handle wrench 3, The barrel 1 is perpendicular to the short-handle wrench 3, and the short-handle wrench 3 can be rotated by pulling the sleeve 1, so that the nuts of ceramic sanitary products can be removed conveniently and quickly, and new spare parts can also be installed conveniently and quickly.

Embodiment 2: A combined wrench, characterized in that it includes a sleeve 1 and a short handle wrench 3, the outer circumference of the lower end of the sleeve 1 is provided with an axial rectangular slot 2, the handle of the short handle wrench 3 The part is located in the rectangular slot 2. The rectangular slots 2 are symmetrically distributed on the outer circumference of the lower end of the sleeve 1 . There are two pairs of the rectangular slots 2 .

The usage method of the present embodiment: common mechanical hands of different types can be cut off to become a short handle wrench 3 and a rectangular slotted hole 2 for matching. When the maintenance space is narrow, first select a suitable short-handle wrench 3 and clamp it on the nut of the ceramic sanitary product to be disassembled, then make the rectangular slot 2 at the lower end of the sleeve 1 fit over the handle of the short-handle wrench 3, The barrel 1 is perpendicular to the short-handle wrench 3, and the nut of the ceramic sanitary product can be removed by pulling the sleeve 1 to make the short-handle wrench 3 rotate. When installing new spare parts, it can also be installed conveniently and quickly. Symmetrically distributed rectangular slots 2 can be arranged on the wall of the sleeve 1, and the handle of the short handle wrench 3 is inserted on the two walls of the sleeve 1, so that the combination of the short handle wrench 3 and the sleeve 1 is more stable and firm. There are two pairs of rectangular slots 2 , that is, four rectangular slots 2 are evenly distributed on the wall of the sleeve 1 , which can be adapted to be installed with different types of short handle wrenches 3 while ensuring the overall strength of the sleeve 1 .

Claims (3)
