[0040] The concept, specific structure and technical effects of the present invention will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present invention.

[0041] It should be noted that, in the description of the present invention, terms such as "upper end", "lower end", "horizontal", "lateral", "inner side", "outer side" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0042] It should also be noted that, in the description of the present invention, terms such as "slightly larger than", "slightly smaller than", "equal to", "hemispherical", "semicircular", etc. indicating the volume and shape of parts are based on the volume sizes and shapes shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific volume or shape. Therefore, it cannot be understood as a limitation on the present invention.

[0043] like Figures 1 to 3 As shown, a telescopic golf club is shown, wherein the bottom end of the shaft 2 is fixedly connected to the club head 1 by AB glue, a grip 3 is sleeved on the upper end of the shaft 2, a plurality of recessed anti-skid patterns are provided on the outer side of the grip 3, a fastening cap 31 which is threadedly engaged with each other is provided at the bottom end of the grip 3, a through hole is opened in the axial direction of the fastening cap 31, the size of the hole is set according to the thickness of the shaft 2, and is used to accommodate the shaft 2 passing through, and a limit column 432 which is threadedly engaged with each other and an activation screw 431 are provided at the top end of the grip 3.

[0044] In the actual production of this embodiment, there will be a slight error in the cross-sectional diameter of the shaft 2. In order to avoid wasting production objects, the opening at the bottom end of the grip 3 needs to be designed to be slightly larger than the cross-sectional area of ​​the shaft 2. However, it is also easy for the opening at the bottom end of the grip 3 to be too large, causing the grip 3 as a whole to shake when used in this embodiment, thereby reducing the user experience. In this case, this problem can be solved by the fastening cap 31 threadedly engaged at the bottom end of the grip 3. On the one hand, the fastening cap 31 is fixedly connected to the grip 3 by threaded engagement, and on the other hand, the fastening cap 31 is fitted with the shaft 2 through the hole at the axis of the fastening cap 31 to fix the horizontal movement trajectory of the grip 3.

[0045] The limiting column 432 and the activation screw 431 arranged at the top of the handle 3 are both components of the activation module 43 in the telescopic assembly 4, and are used to control the relative movement state of the shaft 2 and the handle 3.

[0046] like Figures 4 to 6 As shown, the small end of the T-shaped hollow rod 421 is inserted into the inner side of the rod body 2 and fixedly connected to the rod body 2 by AB glue, the outer diameter of the large end of the T-shaped hollow rod 421 is equal to the outer diameter of the rod body 2, and two horizontally penetrating cylindrical through holes 4211 are provided on the two sides of the large end of the T-shaped hollow rod 421 with the farthest horizontal distance, and a spherical ball 45 is provided in the cylindrical through hole 4211, and the radius of the spherical ball 45 is slightly smaller than the radius of the cylindrical through hole 4211, and the radius of the spherical ball 45 is equal to the height of the cylindrical through hole, and a first hexagonal hollow groove 4212 penetrating longitudinally is also provided in the axial direction of the T-shaped hollow rod 421.

[0047] The outer sides of the upper end and the lower end of the handle 3 are threadedly engaged with the limiting column 432 and the fastening cap 31 respectively; the inner side of the upper end of the handle 3 is provided with a first groove 32 and a spring 435 placed in the first groove 32; a gasket 434 with a hole and a nut 433 are sequentially provided above the spring 435; a second hexagonal hollow groove 33 is further provided downward along the axial direction of the first groove 32; the size of the hollow part of the second hexagonal hollow groove 33 is consistent with the size of the hollow part of the first hexagonal hollow groove 4212; a shaft accommodating groove 34 is provided downward along the axial direction of the second hexagonal hollow groove 33 to the bottom end of the handle 3; the inner diameter of the shaft accommodating groove 34 is slightly larger than the outer diameter of the shaft 2 and is used for sleeve connection of the shaft 2; two hemispherical grooves 35 are further provided on the inner side of the handle 3; the radius of the hemispherical groove 35 is equal to the radius of the ball 45, and the position of the hemispherical groove 35 on the inner side of the handle 3 will be Figures 7 to 9 Detailed description in.

[0048] An inner thread is provided on the outer side of the upper end of the track rod 411 and is used to be screwed with the nut 433, and an outer thread is provided on the inner side of the upper end and is used to be screwed with the small end of the activation screw 431; a large end 4112 is provided on the lower end of the track rod 411, and the cross-sectional area of ​​the large end 4112 is larger than the cross-sectional area of ​​the hexagonal hollow groove 4212; the middle end of the track rod 411 is a hexagonal column 4113, and the hexagonal column 4113 passes through the first hexagonal hollow groove 4212 and the second hexagonal hollow groove 4213 in sequence from bottom to top; two semicircular slide grooves 4114 are provided on the outer sides of the two sides with the farthest horizontal distance of the hexagonal column 4113, and the radius of the semicircular slide groove 4114 is equal to the radius of the cylindrical through hole 4211, and the opening area of ​​the semicircular slide groove 4114 on the hexagonal column 4113 will be Figures 7 to 9 Detailed description in.

[0049] A smooth hole 4321 is provided in the axial direction of the limiting column 432, and the small end of the activating screw 431 can pass through the smooth hole 4321, but the large end of the activating screw 431 cannot pass through the smooth hole 4321. A second groove 4322 is also provided at one end of the limiting column 432 facing the activating screw 431, and the large end of the activating screw 431 can move up and down in the second groove 4322.

[0050] like Figure 7 As shown, when the shaft 2 and the grip 3 are in a stretched (normal use) state, the position of the semicircular groove 4114 is higher than the position of the cylindrical through hole 4211, and the hemispherical groove 35 on the inner side of the grip 3 is connected to the opening on the outer side of the cylindrical through hole 4211. At this time, the ball 45 is squeezed by the hexagonal column 4113 and is clamped between the hemispherical groove 35 and the cylindrical through hole 4211, thereby fixing the relative position of the shaft 2 and the grip 3, so that the two are in a relatively static state. In this state, the ball 45, the cylindrical through hole 4211, and the hemispherical groove 35 play the role of a fixing module in this embodiment.

[0051] like Figure 8 As shown, when the activation screw 431 is pressed, the track rod 411 screwed to the small end of the activation screw 431 moves downward, and the inner opening of the semicircular slide groove 4114 is connected to the cylindrical through hole 4211. At this time, the ball 45 is no longer squeezed by the hexagonal column 4113, and is thus clamped between the semicircular slide groove 4114 and the cylindrical through hole 4211, so that the shaft 2 and the handle 3 can slide relative to each other through the track rod 411. When the track rod 411 slides, its sliding track components including the first hexagonal hollow groove 4212, the second hexagonal hollow groove 33, the ball 45, and the semicircular slide groove 4114 are fixed. In this way, the track rod 411, the first hexagonal hollow groove 4212, the second hexagonal hollow groove 33, the ball 45, and the semicircular slide groove 4114 play the role of the sliding module in this embodiment, and the activation screw 431 plays the role of the activation module in this embodiment.

[0052] like Fig. 9 As shown, when the shaft 2 and the grip 3 are in a tightened state, the shaft 2 slides to the deepest part of the shaft receiving groove 34 under the action of the sliding module, and the cylindrical through hole 4211 and the ball 45 are located at the uppermost position of the semicircular slide groove 4114. The sliding distance of the shaft 2 is the shortened length of the golf club in this embodiment.

[0053] When using this embodiment again, because the ball 45 is already located in the semicircular groove 4114, it is only necessary to directly stretch the shaft 2 and the handle 3. At this time, the shaft 2 and the handle 3 will extend along the direction of the semicircular groove 4114 until the ball 45 is clamped between the hemispherical groove 35 and the cylindrical through hole 4211 again.

[0054] like Figures 7 to 9 As shown, the semicircular slide groove 4114 is located in the upper middle part of the hexagonal column 4113, and when this embodiment is in a stretched state (normal use), the semicircular slide groove 4114 is not connected to the cylindrical through hole 4211, and when the activation screw 431 in this embodiment is pressed, the semicircular slide groove 4114 is connected to the cylindrical through hole 4211; the hemispherical groove 35 is located in the lower middle part of the inner side of the handle 3, and when the present embodiment is in a stretched state (normal use), the hemispherical groove 35 is connected to the cylindrical through hole 4211.

[0055] In this embodiment, the parts that perform the function of the activation module are the activation screw 431, the parts that perform the function of the sliding module are the track rod 411, the first hexagonal hollow groove 4212, the second hexagonal hollow groove 33, the ball 45, and the semicircular slide groove 4114, and the parts that perform the function of the fixing module are the ball 45, the cylindrical through hole 4211, and the hemispherical groove 35.

[0056] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present invention and the technical principles used. Within the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present invention.
