Detailed Description
In order to make the objects, contents and advantages of the present invention clearer, the following description will make a detailed description of embodiments of the present invention with reference to the accompanying drawings and examples.
The present embodiment provides a multi-functional toothed chain wrench, which has a structure as shown in fig. 1 to 3, and includes a multi-functional wrench handle 10, a pull rod 70, a pull rod nut 80, a toothed plate 30, an adjusting groove 12, and a toothed chain 50.
A movable groove 13 for installing the pull rod 70 and the pull rod nut 80 is formed at the center of the inside of the handle body of the multi-functional wrench handle 10, and a rotation groove 11 for rotating the pull rod nut 80 is formed at the middle position of the handle body of the multi-functional wrench handle 10. Four fixing holes for fixing the toothed plate 30 are processed at the top edge of the multifunctional wrench handle 10, and five adjusting grooves 12 for connecting with the toothed chain 50 are processed inside one side of the top edge. In addition, five quincunx plate holes 14 with different specifications are formed in the lower portion of the handle body of the multi-functional wrench handle 10 and are used for screwing five hexagon head bolts with different specifications.
The outer wall of the pull rod nut 80 is processed with anti-slip patterns, and the pull rod nut 80 is installed in the movable groove 13 of the multifunctional wrench handle 10 through the outer wall and can rotate in the movable groove 13. The inner wall of the draw bar nut 80 is formed with a coarse thread, and the draw bar 70 penetrates the draw bar nut 80 and is in contact with the inner wall of the draw bar nut 80 through the thread. The pull rod 70 is driven to move up and down in the movable groove 13 of the multi-function wrench handle 10 by the rotation of the pull rod nut 80.
The toothed chain 50 is formed of a plurality of segments, each of which is secured by a pin 60. Each section is a multi-layer chain plate 51 structure, and the surface of the chain plate 51 with the chain teeth 52 is contacted with the object to be pulled 90. One end of the toothed chain 50 is connected with the top end of the pull rod 70 through the pin 60, and the other end is connected with the adjusting groove 12 of the multi-function wrench handle 10 through the loose pin 20, so that the position of the other end of the toothed chain 50 on the adjusting groove 12 can be properly adjusted according to the size of the object to be wrenched 90.
The castellated plate 30 is fixed to the top edge of the multi-purpose spanner handle 10 by a rivet 40. The castellated plate 30 has a V-shaped structure as a whole for wrenching small-sized articles. The toothed plate 30 has a toothed structure at the contact end with the object to be pulled, so that the contact pressure with the object to be pulled can be increased. The other end opposite to the contact end is embedded in a fixing groove at the top of the multifunctional wrench handle 10.
The working principle of the multifunctional toothed chain type wrench is as follows: when the pull rod nut 80 rotates counterclockwise, the pull rod 70 is driven to move downwards in the movable groove 13 of the multi-function wrench handle 10, and then the sprocket 52 on the toothed chain 50 is driven to contact the object to be wrenched 90 and to be pressed on the toothed plate 30; when the pull rod nut 80 rotates along the needle, the pull rod 70 is driven to move upwards in the movable groove 13 of the multi-function wrench handle 10, and the sprocket 52 on the toothed chain 50 is driven to be loosened from the object to be wrenched 90.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
