[0002] Regarding the installation problem of the "R"-type pins of the disc insulators in the power supply line, the currently commonly used manual flaring method indeed has many inconveniences and potential safety hazards. This traditional method is not only inefficient, consuming a large amount of manpower and time, but also due to the simple tools and limited operating space, it is extremely easy to have accidents during the installation process, posing a threat to the safety of the installers.

[0003] Specifically, when using two pairs of needle-nose pliers or a flat-head screwdriver for flaring operation, due to the lack of a stable clamping and protection mechanism between the tool and the pin, the operator needs to carefully control the force and direction. A slight carelessness may cause the pin to slip off or the tool to slide, thereby scratching the hand or causing other injuries. In addition, long-term delicate operation is also likely to cause hand fatigue, further increasing the risk of operation errors. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, it solves the problems that opening the R-shaped pin is time-consuming and laborious, and during the force application process, due to the lack of a fixing and protection mechanism between the tool and the pin, it is easy to cause accidental injury to the operator.

[0007] As a preferred scheme, the wrench is T-shaped, a groove is opened at the lower end of the "|" part, and insulating handle sleeves are sleeved on the outer sides of the left and right ends of the "-" part.

[0008] As a preferred scheme, the length ratio of the "-" part to the "|" part of the wrench is 2 to 3.

[0009] As a preferred scheme, the through groove is an inverted T-shaped groove.

[0010] As a preferred scheme, the ratio of the widest part to the narrowest part of the inverted T-shaped groove is 1.5 to 2.

[0011] As a preferred scheme, a plurality of protrusions for increasing friction are uniformly arranged in the groove.

[0012] The beneficial effects of the utility model are:

[0013] The utility model solves the problem of difficult and irregular opening of the "R" type pin of the insulator through the base of the matching spanner, and improves the safety during operation and the maintenance efficiency by arranging a protective retaining wall around the operating position.

[0019] To illustrate the features of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments.

[0020] Example:

[0021] See also Figure 1 to Figure 2 , this embodiment provides an R-type pin opening device, comprising a wrench 1 and a base 2, wherein a groove 3 is formed at the bottom end of the wrench 1, and the shape of the groove 3 is adapted to the cross-sectional shape of the R-type pin;

[0022] The base 2 has a through slot 4 on one side thereof facing the side opposite thereto, and the length of the through slot 4 is less than the distance between the two side surfaces. By setting the processing position in the through slot 4, a retaining wall is provided around the processing position. Even if the processing tool slips due to improper operation, it can be stopped by the retaining wall to avoid causing harm to the operator or other persons. In this embodiment, the through slot 4 is also specially set as an inverted T-shaped slot, so that the R-shaped pin 6 has a larger processing space. The ratio of the widest part to the narrowest part of the inverted T-shaped slot is 2, which also makes the base 2 cover a larger area of ​​the wrench 1, and the safety is also improved.

[0023] A vertical column 5 is fixedly arranged on the bottom surface of the through groove 4. During use, the non-open end of the R-shaped pin 6 is sleeved on the vertical column 5, and the groove 3 is stuck on the support rod 61 of the R-shaped pin 6. The wrench 1 is horizontally rotated, and the R-shaped pin 6 is relatively acted on by the wrench 1 and the vertical column 5, and forces are respectively applied to both ends of the R-shaped pin 6 to form an open R-shaped pin. Particularly, in this embodiment, in order to further increase the clamping stability of the groove 3 on the R-shaped pin 6, a plurality of protrusions for increasing friction are uniformly arranged in the groove 3.

[0024] In order to facilitate the application of force in this embodiment, the wrench 1 is set as a T shape. A groove 3 is opened at the lower end of the "|" part, and insulating handle sleeves 7 are sleeved on the outer sides of the left and right ends of the "-" part. During use, the lower end of the "|" part is aligned with the R-shaped pin 6, and the insulating handle sleeves 7 at both ends are held by hand and rotated forcefully. Considering saving effort as much as possible during use, in this embodiment, the length ratio of the "-" part to the "|" part of the wrench 1 is set to 2, so that the ratio of the power arm to the resistance arm is large enough to facilitate the application of force.
