The billiard cue lengthening handle has the advantages of being convenient to use, capable of flexibly adjusting the length of the billiard cue according to the requirements of a user, bringing convenience to the user, enabling the user to operate more comfortably, greatly improving the practicability of the lengthening handle, enabling the improvement modes described by related patents to use the motor and other modes in a matched mode, increasing the use cost by adding related structural books on the basis of the prior art, and not being practical in large numbers of investment use.

Disclosure of Invention

Aiming at the defects of the prior art, the utility model provides a billiard cue extension handle.

In order to solve the technical problems, the utility model provides the following technical scheme:

the billiard cue extension handle comprises an outer sleeve, wherein the outer sleeve is movably connected with the outer side of the inner sleeve;

the outer end of the inner sleeve is connected with the outer sleeve, and the front end of the inner sleeve is fixed with the connecting handle;

a threaded post located at the rear end of the inner sleeve;

and the tensioning ring is movably connected with the outer end of the threaded column.

Preferably, an internal thread is arranged in the tensioning ring, and the internal thread is connected with the external thread of the threaded column.

Preferably, the overall diameter of the overall front section of the threaded column is smaller than the diameter of the rear end.

Preferably, the front section of the connecting handle is fixedly connected with a connecting bolt.

Preferably, a hollow inner tube is arranged on the inner side of the outer sleeve, and a convex strip is fixed on the inner wall of the inner tube.

Preferably, a notch at one end of the tension ring is connected with the convex strip.

The embodiment of the utility model provides a billiard cue extension handle, which has the following beneficial effects:

1. through setting up interior sleeve pipe and outer tube, the outer tube inboard obtains the sand grip and rises tight ring breach department to be connected, the sand grip of outer tube removes in rising tight ring breach department when pulling out the outer tube, and it rotates to rotate the outer tube back outer tube drive sand grip, the sand grip rotates in driving rising tight ring, rotate along the screw thread that the screw post front and back end is different and open, carry out spacing work to outer tube after opening to a certain size, make personnel convenient when using, it is very convenient, retract the in-process also is the same principle, still twist after retracting, rise tight ring and spacing it afterwards.

Drawings

The accompanying drawings are included to provide a further understanding of the utility model and are incorporated in and constitute a part of this specification, illustrate the utility model and together with the embodiments of the utility model, serve to explain the utility model.

FIG. 3 is a schematic view of the inner sleeve structure of the present utility model;

FIG. 4 is a schematic view of the structure of the screw thread post and the tension ring of the present utility model.

In the figure: 1. an outer sleeve; 101. an inner tube; 102. a convex strip; 2. an inner sleeve; 201. a threaded column; 202. a tension ring; 3. a connecting handle; 4. and (5) connecting bolts.

Detailed Description

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings, it being understood that the preferred embodiments described herein are for illustration and explanation of the present utility model only, and are not intended to limit the present utility model.

Examples: as shown in figure 1, the billiard cue extension handle comprises an outer sleeve 1 which is movably connected with the outer side of an inner sleeve 2; an inner sleeve 2, the outer end of which is connected with an outer sleeve 1, and the front end of which is fixed with a connecting handle 3; a connecting bolt 4 fixed to the threaded post 201 at the front end of the connecting handle 3 and located at the rear end of the inner sleeve 2; the tensioning ring 202 is movably connected with the outer end of the threaded column 201; the front section of the connecting handle 3 is fixedly connected with a connecting bolt;

the outer sleeve 1 is mainly an extension handle, a person rotates the outer sleeve 1 to drive the tension ring 202 to open, then the outer sleeve is subjected to limiting work, the inner sleeve 2 is used for connecting the outer sleeve 1, the connecting bolt is used for connecting a billiard cue, and the related use mode can also be used on a dip net, so that the handle is prolonged in a multi-purpose mode.

As shown in fig. 2, an internal thread is arranged in the tension ring 202, the internal thread is connected with an external thread of the thread column 201, and the overall diameter of the whole front section of the thread column 201 is smaller than that of the rear end;

because the tension ring 202 rotates on the threaded column 201, after the diameter of the threaded column 201 at the rear end is larger, the tension ring 202 expands along the threads and then abuts against the inside of the outer sleeve 1, so that the outer sleeve 1 is prevented from moving.

As shown in fig. 3 and 4, the inner side of the outer sleeve 1 is provided with a hollow inner tube 101, the inner wall of the inner tube 101 is fixed with a convex strip 102, and a notch at one end of the tension ring 202 is connected with the convex strip 102;

the inner tube 101 is used for connecting with the inner tube 2, and the convex strips are used for connecting with the tension ring 202.
