Description
Technical field
The utility model relates to mechanical extracting tool, is specifically related to a kind of field operation lamp plug pipe extracting tool.
Background technology
WYD-2000 type field operation lamp is the basic hygienic equipment that Military Medical Institution is extensively allotted, and recoverable amount is very large, uses frequent in work, training.This is equipped in assembling, decomposes in transverse arm and lamp panel process, if misoperation, the situation of transverse arm plug pipe fracture easily occurs.Due to factors such as Design and manufactures, transverse arm plug pipe fracture stump is inner at lamp holder, makes dismounting very difficult.
Utility model content
The purpose of this utility model is to provide a kind of field operation lamp plug pipe extracting tool.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: provide a kind of field operation lamp plug pipe extracting tool, comprise
Screw rod, one end of screw rod is the connection recess with pin-and-hole, and horizontal being inserted with of the other end stirs thick stick;
Two chelas, each chela comprises chela link and clamping part, and chela link is provided with pin-and-hole, and two chelas connect recess both sides by rotating being fixed on of pin; The outside of clamping part is followed closely with pawl, and is provided with spring between two clamping parts;
Packing ring, packing ring is actively socketed on screw rod periphery, and is outside equipped with support ring at packing ring;
Handwheel, the internal thread of handwheel engages with the external screw thread of screw rod, and is arranged on packing ring and stirs between thick stick.
Instrument of the present utility model, can go deep into lamp holder inside, uses the pin of chela to fix, and by rotating the extruding force that handwheel produces, lifting out, complete dismounting by plug pipe in lamp holder.

Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in detail.
In an embodiment of the present utility model, as shown in Figure 1, provide a kind of field operation lamp plug pipe extracting tool, comprise screw rod 5, chela 1, packing ring 7 and handwheel 8.
One end of screw rod 5 is the connection recess with pin-and-hole, and horizontal being inserted with of the other end stirs thick stick 9.Chela 1 has two, and each chela 1 comprises chela link 10 and clamping part 11, and chela link 10 is provided with pin-and-hole, and two chelas 1 connect recess both sides by rotating being fixed on of pin 4.The outside of clamping part 11 with pawl nail 2, and is provided with spring 3 between two clamping parts 11.Packing ring 7 is actively socketed on screw rod 5 periphery, and is outside equipped with support ring 6 at packing ring 7.The internal thread of handwheel 8 engages with the external screw thread of screw rod 5, and is arranged on packing ring 7 and stirs between thick stick 9.Have hole inside the clamping part 11 of chela 1, spring 3 is arranged in hole.Handwheel 8 is provided with anti-skidding striped.
Operation principle of the present utility model and process:
The utility model is mainly for WYD-2000 type field operation lamp, and after the fracture of this operating lamp plug pipe, breaking part generally has a segment distance from the mouth of pipe, and as shown in Figure 4, in Fig. 4, innermost layer is columniform plug pipe.Because plug pipe position is low, make the bad pipe that pulls the plug out of the socket, plug pipe bottom end is with two pin-and-holes.When using this instrument, compressed by chela 1, extrusion spring 3 makes chela 1 shrink, and makes it can put into plug pipe.After chela 1 puts into plug pipe, adjustment pawl nail 2 embeds in the pin-and-hole of plug pipe, and then chela opens.
The clamping part of chela 1 inserts plug pipe, allows pawl follow closely 2 and relies on the strength of spring to enter the pin-and-hole of fracture plug pipe, open catch on from inner side.Then keep stirring thick stick 9 motionless, rotating handwheel 8 makes it move along screw rod 5 to chela 1 front end, promotion packing ring 7 and support ring 6 move in the same way, withstand mouthpiece outer, fracture plug pipe stump pulls out by the axial displacement utilizing handwheel 8 and screw rod 5 to produce in mouthpiece, completes the dismounting of plug pipe fracture stump.
Although describe in detail detailed description of the invention of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
