DETAILED DESCRIPTION

The present invention is further described in detail below in conjunction with the embodiments, but the embodiments of the present invention are not limited thereto. It should be noted that the "left" and "right" in the following are not intended to limit the components in the solution to be installed on the left or right side, but are intended to more conveniently describe the specific technical solution of the present solution. The left pliers hand 1 and the right pliers hand 2 in the present invention can be designed to have the same structure, and can also be adaptively improved according to hand-holding habits.

Example 1

This embodiment takes the maintenance of the safety barrier in a cabinet of the company as an example to further illustrate this solution. Now it is necessary to remove the retaining spring on the safety barrier and inspect the safety barrier in the cabinet. The shape of the safety barrier here is a conventional cylindrical structure as shown in Figure 4.

In this embodiment, the circlip pliers of the utility model for disassembling and installing the circlip 6 on the safety barrier 7 belong to the technical field of maintenance tools for the safety barrier 7 in the cabinet. Referring to Figures 1 and 2, the circlip pliers include a left pliers hand 1 and a right pliers hand 2. Both the left pliers hand 1 and the right pliers hand 2 are arc-shaped structures matching the appearance of the safety barrier 7. The left pliers hand 1 is connected to the right pliers hand 2 by a hinge 3. The left pliers hand 1 includes a pliers handle A1.1 and a pliers head A1.2. The pliers head A1.2 is provided with an extension part A1.3 for passing through the circlip hole on the circlip 6. The right pliers hand 2 includes a pliers handle B2.1 and a pliers head B2.2. The pliers head B2.2 is provided with an extension portion B2.3 for passing through the retaining spring hole on the retaining spring 6. When in use, the pliers head A1.2 and the pliers head B2.2 cooperate to cover the matching retaining spring 6. A reset spring 4 is connected between the pliers handles of the left pliers hand 1 and the right pliers hand 2. When the pliers handles (pliers handle A1.1, pliers handle B2.1) are pinched, the pliers head A1.2 is separated from the pliers head B2.2; when the pliers handles are loosened, the pliers head A1.2 and the pliers head B2.2 are closed.

In a more preferred embodiment, referring to FIG3 , the distal ends of the extension parts A1.3 of the pliers A1.2 and B2.3 of the pliers B2.2 are flat-mouthed plugs, which are convenient for accurately inserting into the retaining ring mouth and easily disassembling the retaining ring 6. The two ends are subjected to force and are not easy to fall off after being subjected to force. Because of the effect of the spring of the handle part, only one-way force is required, and the operation is simple and labor-saving. Referring to FIG5 , FIG5 is a schematic diagram of the structure in the use state.

Preferably, the hinged part 3 is preferably a rivet, which has a simple structure, low cost, and is not easy to loosen, ensuring that when the pliers handle is loosened, the extension of the pliers head of the left pliers hand 1 corresponds to the extension of the pliers head of the right pliers hand 2, so as to facilitate the quick tightening or removal of the retaining ring 6. In addition, the pliers head of the retaining ring pliers matches the shape of the safety gate 7. Figure 3 is a front view of the safety gate 7, which is the shape of the common safety gate 7 (cylindrical). The slender pliers head can effectively avoid the influence of the wiring terminal of the safety gate 7, can fit the peripheral side of the safety gate 7, and the extension of the pliers head is very convenient to be clamped into the retaining ring mouth of the retaining ring 6 of the safety gate 7; during processing, the joint of the retaining ring 6 is matched, so that the retaining ring 6 can be easily clamped without falling off. This saves time and easily removes the safety gate 7.

More preferably, the pliers heads of the left pliers hand 1 and the right pliers hand 2 are rigid metal parts.

More preferably, a sheath 5 is provided on the outer side of the end of the pliers handle.

The circlip pliers of the utility model are used to assist in removing the circlip 6 on the safety barrier 7. The disassembly and installation time of a single circlip 6 is significantly shortened. Compared with the previous working method without using the circlip pliers, a total of 2/3 of the operation time can be saved, and the work intensity of the staff can be significantly reduced. The standardization of the operation process can be improved, the discipline of incorrect operation during the operation process can be reduced, the damage rate of the safety barrier 7 and the circlip 6 can be reduced, and the safety during operation can be improved.

The circlip pliers in the present scheme are provided with an extension portion that can pass through the circular hole on the circlip 6. When it is necessary to install the circlip 6, the clamp handles of the circlip pliers are pinched, the clamp heads of the circlip pliers are separated, the circlip 6 is placed between the clamp heads of the circlip pliers, and the extension portion of the circlip pliers is clamped into the circlip opening of the circlip 6. The circlip pliers are used to fit the circlip 6 to the surrounding side of the safety barrier 7, the clamp handles are loosened, and the clamp heads are closed. With the assistance of the circlip pliers, the circlip openings at both ends of the circlip 6 are tightly together, and the staff no longer needs to find the two circlip openings of the circlip 6, and can conveniently install and tighten the circlip 6; when it is necessary to remove the circlip 6, the extension portion of the circlip pliers is first inserted into the circlip opening of the circlip 6, and then the pliers handles are pinched, so that the circlip 6 on the safety barrier 7 can be quickly removed, which is convenient and safe to operate. The retaining ring 6 in this solution is still installed at the bottom of the safety barrier 7 and is still blocked, and the position of the retaining ring 6 cannot be seen intuitively. However, when using the retaining ring pliers, with the assistance of the retaining ring pliers, the worker no longer needs to find and align the mounting holes on the retaining ring 6, because the two mounting holes on both ends of the retaining ring 6 are kept aligned under the action of the reset spring 4 when the retaining ring pliers are loosened, and the shapes of the left clamp hand 1 and the right clamp hand 2 of the retaining ring pliers are matched with the safety barrier 7. Compared with conventional long flat-blade screwdriver tools, it is less likely to have safety hazards such as slipping out of the hands. At the same time, the use of the retaining ring pliers can complete the operation at one time, which is very convenient, saves time and effort, and is easy to operate successfully.
