Abstract
The utility model provides an ejector pin clamp which is characterized in that a handle with n-shaped legs is included; concentric holes are arranged on the two legs; the aperture of the hole on one leg is larger than that of a cotter pin, and the inside of the hole on the other leg is provided with screw threads and a compaction screw rod; the center of the screw rod is provided with a thread hole, the inside of which is provided with an ejector pin screw rod, wherein, the diameter of the head part of the ejector pin screw rod is same with that of the cotter pin; the tail part of the ejector pin screw rod is provided with a hole used for perforating a small steel stick twisting the ejector pin screw. The ejector pin clamp has simple structure, light weight of the whole body and convenient carrying, saves time and labor and greatly improves the work efficiency.
Description
Technical field
The utility model belongs to instrument, is the ejector pin pincers that the maintenance of a kind of supply line is used specifically.
Background technology
In recent years, along with the circuit life cycle increases, the gold utensil on the circuit also exposing to the weather constantly aging down, and the problem of aging especially severe of split pin, the split pin that has in less than year with regard to seriously corroded.And when changing, get to come out in perforation because of the split pin rust, can not in time change and the hidden danger that causes the accident.In the circuit that our circuit class is administered, 30% circuit occurs the dead phenomenon of split pin rust, and often occur in this case, use instrument such as common pliers to be difficult to it is extracted, sometimes get and use fully about 10--25 minute in order to extract the dead split pin of a rust, consume the time of maintenance greatly, prolonged electric power feeding time.
Summary of the invention
The purpose of this utility model is to overcome the existing deficiency of using general tool, and a kind of structure power supply station simpler, easy to use and high efficiency ladder of checking meter is provided.
The purpose of this utility model is achieved in that
A kind of ejector pin pincers, it is characterized in that: the handle that a band " n " font legs and feet are arranged, on two legs and feet a concentric holes is arranged, hole on legs and feet, the aperture is greater than split pin, and the hole inside fire attack on another legs and feet has screw thread and adorns a clamping screw, and there is screwed hole at the screw rod center, an ejector pin lead screw that head is identical with the split pin diameter is housed in the screwed hole, and the afterbody of ejector pin lead screw has a hole that is used to wear the little steel rod of twisting ejector pin lead screw.
The purpose of this utility model advantage and good effect are:
1, uses ejector pin pincers worker tool, can play and shorten time of pulling pin or writing off with nail and time saving and energy saving multi-efficiency.By practice, can save nearly about 15 minutes working times, a circuit calculates by 10 basic bars, can save about 150 minutes clock times, thereby increase work efficiency greatly, shortens power off time, for quality supply plays a role.
2, the ejector pin wrench structure is simple, and is easy to carry, and overall weight is no more than 1.5kg.
3, kit cost less than is 120 yuan.
Description of drawings
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structural front view;
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Shown in Figure 1, be a kind of ejector pin pincers of the utility model; Ejector pin pincers have on 1, two legs and feet of handle of a band " n " font legs and feet a concentric holes are arranged, and the hole on legs and feet, aperture be greater than split pin, or the cover 5 of aperture greater than split pin is housed in the hole on these legs and feet.Hole inside fire attack on another legs and feet has screw thread and adorns a clamping screw 2, there is screwed hole at the screw rod center, an ejector pin lead screw 3 that head is identical with the split pin diameter is housed in the screwed hole, and the afterbody of ejector pin screw rod has a hole that is used to wear twisting ejector pin lead screw steel rod 4.
The ejector pin pincers will have an end of ejector pin lead screw head to be inserted on the eyelet for the treatment of service parts of corrosion split pin in use, near the other end being stuck on the other end eyelet of corrosion split pin, be used to wear the little steel rod rotation ejector pin lead screw in ejector pin lead screw afterbody hole then, the ejector pin lead screw is constantly rotated, up to the split pin of corrosion is pushed up to other end outlet from an end, thereby reached time saving and energy saving double effects.
Claims (2)
1, a kind of ejector pin pincers, it is characterized in that: the handle (1) that a band " n " font legs and feet are arranged, on two legs and feet a concentric holes is arranged, hole on legs and feet, the aperture is greater than split pin, and the hole inside fire attack on another legs and feet has screw thread and adorns a clamping screw (2), and there is screwed hole at the screw rod center, an ejector pin lead screw (3) that head is identical with the split pin diameter is housed in the screwed hole, and the afterbody of ejector pin lead screw has a hole that is used to wear the twisting little steel rod of ejector pin lead screw (4).
