Description

Novel multifunctional chain wrench
Technical Field
The utility model relates to a hardware and tools field, in particular to novel multi-functional chain spanner.
Background
The existing chain wrench is limited by the size and the structure of the chain, and can only be adjusted one by one according to the buckles of the chain when the length of the chain is adjusted, so that the accurate adjustment cannot be realized.
Disclosure of Invention
The utility model aims at providing a novel multi-functional chain spanner in order to solve above-mentioned problem.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a novel multi-functional chain spanner, includes adjusting nut, outer tube, adjustment ejector pin and chain, adjustment ejector pin upper end periphery be equipped with adjusting nut complex screw thread, adjusting nut connects to be fixed on the outer tube top, the outer tube cover is peripheral at the adjustment ejector pin, the chain both ends are connected respectively and are fixed in the relative both sides of outer tube.
The utility model discloses a chain spanner passes through the chain and adjusts the ejector pin cooperation and presss from both sides tight workpiece, through screw thread and the adjusting nut cooperation on the adjustment ejector pin, realizes that the relative adjusting nut of adjustment ejector pin reciprocates, can realize continuous accurate adjustment, has solved the difficult problem that current chain spanner adjustment precision is not high.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of a novel multifunctional chain wrench according to a preferred embodiment of the present invention;
in the figure: 1. adjusting the nut; 2. an outer sleeve; 3. adjusting the ejector rod; 4. a chain; 5. a handle; 6. and a nut.
Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.
As shown in fig. 1, the novel multifunctional chain wrench of a preferred embodiment of the present invention comprises an adjusting nut 1, an outer sleeve 2, an adjusting post rod 3, a chain 4 and a handle 5.
The periphery of the upper end of the adjusting ejector rod 3 is provided with a thread matched with the adjusting nut 1, so that the adjusting ejector rod 3 can be matched with the adjusting nut 1 through the thread to realize the up-and-down movement of the adjusting ejector rod 3 relative to the adjusting nut 1. The top end of the adjusting ejector rod 3 (for directly abutting against the working part) is provided with a fine tooth-shaped structure or an anti-skid pattern for increasing the friction force between the adjusting ejector rod 3 and the working part (in this embodiment, the working part is a nut 6 to be disassembled). The bottom end of the adjusting ejector rod 3 is fixedly connected with the grab handle 5 in a welding way, and the adjusting of the adjusting ejector rod 3 can be more convenient and labor-saving by holding the grab handle 5. The adjusting ejector rod 3 is cylindrical. The grab handle 5 is round and cake-shaped, and the diameter of the grab handle 5 is larger than that of the adjusting ejector rod 3.
The outer sleeve 2 is a supporting part of the whole chain wrench and is also a force application arm of force of the whole chain wrench, is used for rotating after clamping a working part and can play a role in protecting and adjusting threads on the ejector rod 3. The outer sleeve 2 is sleeved on the periphery of the adjusting ejector rod 3. The length of the outer sleeve 2 is less than that of the adjusting ejector rod 3.
The adjusting nut 1 is fixed at an opening at the top end of the outer sleeve 2 through welding connection and is used for being matched with the adjusting ejector rod 3 to realize up-and-down movement.
Two ends of the chain 4 are respectively connected and fixed at two opposite sides of the periphery of the outer sleeve 2 and are used for matching with the adjusting ejector rod 3 to clamp the working part together.
The utility model discloses during the use, overlap chain 4 at the working part periphery earlier, then adjustment ejector pin 3 passes outer tube 2 spiral shell and closes screw in adjusting nut 1, makes 3 tops of adjustment ejector pin stretch out adjusting nut 1's screw socket, through screwing adjustment ejector pin 3, supports adjustment ejector pin 3 tightly on the working part to chain 4 and the common chucking working part of adjustment ejector pin 3 cooperation. Finally, the disassembly and fastening of the working parts are achieved by rotating the outer sleeve 2.
The utility model discloses a chain spanner passes through chain 4 and the tight working part of adjustment ejector pin 3 cooperation clamp, through screw thread and the cooperation of adjusting nut 1 on the adjustment ejector pin 3, realizes that adjustment ejector pin 3 relative adjustment nut 1 reciprocates, can realize continuous accurate adjustment, has solved the not high difficult problem of current chain spanner adjustment precision.
Additionally, the utility model relates to a novel multi-functional chain spanner both can realize the accurate adjustment of length, can increase again and the working part between the chucking dynamics, the effect is safe, not damaged working part's phenomenon. Not only greatly reducing the physical labor of operators, but also improving the working efficiency.
The above descriptions of the embodiments of the present invention that are not related to the present invention are well known in the art, and can be implemented by referring to the well-known technologies.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
