FIG. 2 is a cross-sectional view of the insertion hole of the extension rod of the modular tool holder;

FIG. 3 is a schematic view of the installation of the modular handle extension rod;

wherein: 100-rod body, 200-plug, 201-locking pin hole, 300-jack, 301-matching surface, 302-screw hole and 400-bolt.

Detailed Description

The invention is further illustrated below by means of specific examples:

as shown in fig. 1, a modular handle extension bar includes a bar body 100, a plug 200, and a socket 300.

The rod body 100 is cylindrical, and the plug 200 and the insertion hole 300 are respectively positioned at the front end and the rear end of the rod body 100. The plug 200 is in a cylindrical shape concentric with the rod body 100 and having a smaller diameter than the rod body 100, and three planes are equally spaced along the circumference of the sidewall of the plug 200. The three planes are respectively provided with locking pin holes 201 on the same horizontal line, the three locking pin holes 201 extend towards the axial direction of the plug 200 in a forward inclining way, and the inclination angle is 50-65 degrees. Specifically, to ensure sufficient strength of both plug 200 and socket 300, the diameter of plug 200 is preferably half the diameter of shaft 100.

As shown in fig. 2, the shape of the socket 300 is identical to that of the plug 200, the inner wall of the socket 300 has three mating surfaces 301 matching with the outer wall plane of the plug 200, the outer surface of the rod 100 has a screw hole 302, the screw hole 302 extends forward towards the axial direction of the socket 300 and penetrates into the socket 300 from the mating surface 301. When two modular extension poles are connected, the plug 200 of the latter modular extension pole can be inserted into the socket 300 of the former modular extension pole, and the screw hole 302 and the pin hole 201 are matched with each other. The inclination angle of the screw hole 302 is consistent with that of the locking pin hole 201 and is 50-65 degrees.

Above is the concrete structure of the utility model, as shown in fig. 3, during the use, insert the plug 200 of this handle of a knife extension rod in the lathe mounting hole and fix, jack 300 is used for installing the cutter. When the problem that the length of the cutter is not enough is met, the cutter is detached, the plug 200 of the other cutter handle extension rod is inserted into the jack 300 of the current cutter handle extension rod, the two cutter handle extension rods are fixed together by bolts which sequentially extend into the screw holes 302 and the locking pin holes 201, and then the cutter is fixed in the jack 300 of the other cutter handle extension rod, so that the effect of extending the length of the cutter can be realized. Of course, more than two handle extension rods can be installed according to needs to obtain a better extension effect.

Through setting up in plug 200 outer wall upper surface and setting up fitting surface 301 on jack 300 inner wall, restricted the relative slip between two handle of a knife extension rod, make it can bear big moment of torsion and rotate, improved the transmission stability of handle of a knife extension rod circumferencial direction. Through the screw hole 302 and the locking pin hole 201 which are arranged in a forward inclining manner, when the tool holder extension rod is locked by the bolt, axial and radial locking forces can be generated simultaneously, and the axial and radial matching between the two tool holder extension rods is tighter. By adopting the mode of evenly distributing 3 screw holes 302 and locking pin holes 201 along the circumferential direction, the stress is concentrated at the axis of the extension rod, and the installation is more stable.

More synthesize, the utility model discloses the installation is swift simple and convenient, and locking force is strong, and axial transmission moment of torsion is big, is fit for the heavy high-power cutting scene of carrying more. The three-point locking mechanism with the angle is high in positioning precision and strong in locking force, machining precision can be effectively guaranteed, and production cost is reduced.

However, those skilled in the art should realize that the above embodiments are only for illustrative purposes and are not to be used as limitations of the present invention, and that changes and modifications to the above embodiments are intended to fall within the scope of the appended claims, as long as they fall within the true spirit of the present invention.
