[0031] In one embodiment of this utility model, such as Figures 1-3As shown, a high-bending-resistance billiard cue handle is provided, including an upper section 1, a lower section 2, and a spindle 3. The spindle 3 includes an integrally formed upper spindle body 31 and a lower spindle body 32. A first step 33 is formed at the connection between the upper spindle body 31 and the lower spindle body 32. The upper section 1 has an upper mounting hole 11 adapted to the upper spindle body 31, and a mounting sleeve 12 coaxial with the upper mounting hole 11 protrudes from the connecting end. The lower section 2 has a lower mounting hole 21 adapted to the lower spindle body 32. The inner side of the mounting sleeve 12 is adapted to the upper spindle body 31, the outer side is threaded to the lower mounting hole 21, and the end abuts against the first step 33. The upper mounting hole 11 of the upper section 1 mates with the upper shaft body 31 of the spindle 3, and the lower mounting hole 21 of the lower section 2 mates with the lower shaft body 32 of the spindle 3. The upper section 1 and the lower section 2 are fixed on the same axis by the spindle 3, which helps to improve the bending resistance of the billiard cue handle. The first step 33 abuts against the mounting sleeve 12, providing a resisting force for the spindle 3 in the axial direction, thereby reducing the possibility of the spindle 3 loosening in the axial direction due to vibration caused by the ball, which helps to improve the accuracy of power transmission and ensure the user's hitting feel. Specifically, the outer side of the mounting sleeve 12 is provided with external threads, and the inner hole of the lower mounting hole 21 is provided with internal threads corresponding to the external threads.

[0032] In one embodiment of this utility model, the mandrel 3 is made of one of carbon fiber, glass fiber, or aluminum. In this embodiment, the mandrel 3 is made of carbon fiber, which is lightweight and has better strength, thus improving the connection between the upper section 1 and the lower section 2.

[0034] In one embodiment of this utility model, such as Figure 2 As shown, the solid shaft 4 includes an integrally formed first shaft 41 and a second shaft 42. The connection between the first shaft 41 and the second shaft 42 is formed by a second step 43. The inner wall of the mandrel 3 is provided with a third step 34 that abuts against the second step 43. Specifically, the abutting cooperation between the second step 43 and the third step 34 provides a resisting force for the solid shaft 4 in the axial direction, thereby reducing the possibility of the solid shaft 4 becoming loose in the axial direction due to vibrations caused by hitting the ball.

[0035] In one embodiment of this utility model, such as Figure 1As shown, the rear end of the second shaft 42 extends rearward, is exposed outside the mandrel 3, and is adapted to the lower mounting hole 21. By reducing the length of the carbon fiber mandrel 3, the manufacturing cost of the product is further reduced.

[0036] In one embodiment of this utility model, such as Figure 3 As shown, a fourth step 421 is formed between the exposed section of the second shaft 42 and the shaft body, and the rear end opening of the mandrel 3 abuts against the fourth step 421. Specifically, the fourth step 421 is coated with adhesive, and the rear end opening of the mandrel 3 is bonded to the fourth step 421 by the adhesive, further improving the structural stability of the mandrel 3.

[0037] In one embodiment of this utility model, such as Figure 1 As shown, it also includes a counterweight device 5, which is located at the rear end of the second shaft 42. The counterweight device 5 is a screw that is threaded onto the second shaft 42. The structure is simple and easy to assemble.
