Description
Technical Field
The utility model relates to a universal tool field especially relates to a ejector pin formula chain spanner.
Background
Chain wrenches, also known as chain tongs. In the prior art, a chain wrench is usually arranged in a manner that a chain is hinged on a wrench handle, and a hanging ring is arranged on the other side of the hinged side of the chain. When the device is used, the chain is hooked on the hanging ring, and various pipe fittings and connecting pieces are rotated by the friction force of the chain. However, this arrangement has certain disadvantages. The first is that the existing chain wrench completely performs the screwing operation on the connecting piece through the friction force of the chain, and once the connecting piece is over-tightened, the chain slides idly. The second chain fixed length, the link gear is limited, just also two grades are just general, can not exceed third grade at most, and its suitability is extremely poor.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art weak point, provide a stable performance, safe and reliable can adjust in a flexible way, dismantles all kinds of material connecting pieces and all can provide effective supplementary ejector pin formula chain spanner.
The equipment comprises a holding part and an adjusting chain;
the holding part comprises a holding rod, and the holding rod is a main supporting part of the equipment and is also a part for holding and exerting force when in use. The outer wall of the rod body of the holding rod is in a threaded form, a holding handle is integrally arranged at the bottom of the holding rod, and the holding handle is in an annular form so as to be held by a user.
The adjusting chain comprises a chain and an adjusting threaded sleeve, the adjusting threaded sleeve is in a threaded sleeve type formed by injection molding of the inner wall, and the chain is arranged on the outer wall of the adjusting threaded sleeve.
The outer wall threads of the holding rod are matched with the inner wall threads of the adjusting screw sleeve, and the holding rod is screwed in the adjusting screw sleeve. The holding rod is screwed in to be pressed against the surface of the workpiece, so that the using length of the chain can be adjusted.
Furthermore, the outer wall of the adjusting threaded sleeve is fixedly provided with a connecting lug plate, and the chain is hinged to the connecting lug plate.
Furthermore, the holding rod is integrally provided with a top head on the top surface, the top head is in a square form, and the top surface of the top head is a plane, so that the holding rod can be better attached to the edge surface of the workpiece.
Furthermore, a rubber pad is covered on the surface of the top plate.
The utility model discloses during the use to dismantle the nut example, establish the chain cover on the nut, precession holding rod makes the top of holding rod top surface closely laminate in one of them stupefied face of nut, makes the chain be in the tight state that rises, moves the gripping handle through twisting, dismantles the nut. The stepless adjustment mode can flexibly control the tightness of the chain around the nut, namely, the stepless adjustment mode is suitable for the disassembly work of the nut with one size.
The utility model has the advantages that: the utility model discloses simple structure, convenient to use, low in cost and easy maintenance have realized the electrodeless regulation of chain spanner through simple structure, to fasteners such as the nut of various models, connecting piece homoenergetic adaptation in a flexible way.

Detailed Description
Referring to fig. 1, the utility model discloses a push-rod type chain spanner including holding pole 3, holding pole 3 is the main supporting component of this equipment, also is the part that grips the power when using. The outer wall of the rod body of the holding rod 3 is in a threaded form, a holding handle 2 is integrally arranged at the bottom of the holding rod, and the holding handle 2 is in an annular form so as to be held by a user.
The adjusting chain 1 comprises a chain 1 and an adjusting threaded sleeve, the adjusting threaded sleeve is in a threaded sleeve form formed by injection molding of the inner wall, and the chain 1 is arranged on the outer wall of the adjusting threaded sleeve.
The outer wall threads of the holding rod 3 are matched with the inner wall threads of the adjusting screw sleeve, and the holding rod 3 is in threaded connection with the adjusting screw sleeve. The length of the chain 1 can be adjusted by screwing the holding rod 3 into the holding rod to press the holding rod against the surface of a workpiece.
Furthermore, the outer wall of the adjusting threaded sleeve is fixedly provided with a connecting lug plate, and the chain 1 is hinged to the connecting lug plate.
Further, an ejector head 4 is integrally arranged on the top surface of the holding rod 3, the ejector head 4 is in a square form, and the top surface of the ejector head 4 is a plane, so that the holding rod 3 can be better attached to the edge surface of a workpiece.
Further, the surface of the top plate is covered with a rubber pad 5.
The utility model discloses during the use to dismantle the nut example, establish chain 1 cover on the nut, precession holding rod 3 makes the top 4 of holding rod 3 top surface closely laminate in one of them stupefied face of nut, makes chain 1 be in the tight state that rises, moves gripping handle 2 through twisting, dismantles the nut. The stepless adjustment mode can flexibly control the tightness of the chain 1 around the nut, namely, the stepless adjustment mode is suitable for the dismounting work of the nut with one size.
