[0066] See also Figures 1 to 12 As shown, a three-dimensional exploded view of the preferred embodiment of the bicycle clamping device of the utility model is described in detail. The bicycle clamping device 1 of the utility model comprises:
[0067] The tube assembly 2 comprises a first tube body 20 and a second tube body 21. The first tube body 20 has a first positioning portion 200 and a first connecting portion 201 at both ends thereof and has a first tube inner space 202. The first tube inner space 202 has a closing portion 203 and an opening 204 at both ends thereof. The first connecting portion 201 of the first tube body 20 has a concave receiving groove 205 and is not connected to the first tube inner space 202 by the closing portion 203. The second tube body 21 is pivotally disposed in the first tube inner space 202 of the first tube body 20. One end of the second tube body 21 is adjacent to the closing portion 203 and the other end protrudes outward from the first tube body 20 through the opening 204. A limiting rib 210 is concavely disposed on the tube surface of the second tube body 21 and has a second tube inner space 211.
[0068] The first quick-release assembly 3 has a connecting piece 30 connected to the first connecting portion 201 of the first tube body 20, and the first quick-release assembly 3 also has a first transmission rod 31, a first handle 32, a push piece 33 and a first elastic piece 34. One end of the first transmission rod 31 is pivotally connected to the first handle 32 and the other end is penetrated by the connecting piece 30 and is arranged in the second tube inner space 211 of the second tube body 21. The push piece 33 is assembled to the end of the first transmission rod 31 and has a limiting groove 330 corresponding to the limiting rib 210 of the second tube body 21. The first elastic piece 34 is assembled on the first transmission rod 31 and one end is against the push piece 33, and the other end is against the closing portion 203.
[0069] The positioning assembly 4 comprises a first fixing member 40 and a second positioning portion 41 which is mutually positioned with the first positioning portion 200 of the first tube 20. The first fixing member 40 longitudinally penetrates the positioning assembly 4 and the second tube 21 and is fixed to the first transmission rod 31. The positioning assembly 4 moves with the first transmission rod 31. In this embodiment, the first positioning portion 200 and the second positioning portion 41 have a first tooth surface 2000 and a second tooth surface 410 which mesh with each other.
[0070] The clamping assembly 5 has an upper clamping portion 50 and a lower clamping portion 51 and a clamping space 52 whose size changes as the lower clamping portion 51 pivots up and down, and the upper clamping portion 50 and the lower clamping portion 51 have corresponding pivoting assemblies 53. Specifically, the upper clamping portion 50 has a fixing seat 500 fixedly connected to the second tube 21, and the fixing seat 500 and the second tube 21 are sequentially penetrated by the second fixing member 54 and finally fixed to the upper clamping portion 50, so that the clamping assembly 5 is assembled on one side of the second tube 21 and forms a synchronous relationship with the second tube 21, the first transmission rod 31 and the first handle 32. When the first handle 32 is rotated, the first transmission rod 31, the second tube 21 and the clamping assembly 5 are driven to rotate coaxially. In addition, a second handle 55 is pivotally provided at the middle section of the upper clamping portion 50, and the second handle 55 is pivotally connected to an adjusting member 550. The adjusting member 550 is downwardly passed through the upper clamping portion 50 and fixedly connected to the lower clamping portion 51. When the second handle 55 is pulled upward, the adjusting member 550 moves downward to make the lower clamping portion 51 swing downward.
[0071] In conjunction with the expansion and contraction of the second elastic member 551 on the adjusting member 550 , the size of the clamping space 52 of the clamping assembly 5 can be changed, and the size of the clamping space 52 can be adjusted according to the tube diameters of different bicycles B to achieve the best clamping effect.
[0072] The tripod assembly 6 has a telescopic tube assembly 60 and a pivoting portion 61 disposed at the top of the telescopic tube assembly 60. The first tube body 20 of the tube body assembly 2 further has a pivoting tube 206.

The second quick release assembly 62 has a handle 620. In addition, a tool placement tray 63 (for placing maintenance tools) is provided at an appropriate position of the telescopic tube assembly 60 and a support seat 64 (such as Fig.12 In this embodiment, by pulling the handle 620 of the second quick release assembly 62 to one side, the pivoting portion 61 at the top of the telescopic tube assembly 60 can be rotated downward to form a folded state, which is convenient for carrying and does not take up space.
[0073] Next, the combined structure of the best embodiment of the bicycle clamping device 1 of the utility model is further described:
[0074] First, the second tube body 21 is pivotally assembled to the first tube inner space 202 of the first tube body 20, and one end of the second tube body 21 protrudes outward from the first tube body 20 through the opening 204. Then, the first transmission rod 31 of the first quick-release assembly 3 is inserted into the second tube inner space 211 of the second tube body 21. One end of the first transmission rod 31 is assembled with the push-pull member 33. The push-pull member 33 and the limit rib 210 of the second tube body 21 are mutually limited by the limit groove 330. The first elastic member 34 is sleeved on the first transmission rod 31, and the two ends of the first elastic member 34 are respectively disposed on the push-pull member 33 and the closed portion 203 of the first tube inner space 202. Afterwards, the second positioning portion 41 of the positioning assembly 4 is arranged correspondingly to the first positioning portion 200 of the first tube 20, and the positioning assembly 4 and the first tube 20 are meshed and positioned with each other by means of the first tooth surface 2000 and the second tooth surface 410, and then the first fixing member 40 is longitudinally axially penetrated through the positioning assembly 4 and the second tube 21 and fixed to the first transmission rod 31, so that the positioning assembly 4 and the first transmission rod 31 are synchronized. Afterwards, the fixing seat 500 of the upper clamping portion 50 of the clamping assembly 5 is assembled on one side of the second tube 21, and the fixing seat 500 is penetrated through the second fixing member 54, and the second tube 21 is finally fixed to the upper clamping portion 50, so that the clamping assembly 5 and the second tube 21, the first transmission rod 31 and the first handle 32 are synchronized, and the size of the clamping space 52 can be changed by the upper clamping portion 50 and the lower clamping portion 51 through the pivoting assembly 53. When the first handle 32 is rotated, the first transmission rod 31 , the second tube 21 and the clamping assembly 5 are driven to rotate coaxially.
[0075] Next, the use of the bicycle clamping device 1 of the utility model in the best embodiment is further described:
[0076] First, place the support base 64 of the tripod assembly 6 on the ground, and the top pivoting portion 61 is pivotally connected to the pivoting tube 206 of the first tube body 20 through the second quick release assembly 62, and the telescopic tube assembly 60 can be adjusted up and down. Figure 4 As shown in FIG. 1 ), the first transmission rod 31 pivotally connected to the first handle 32 moves forward, and the first elastic member 34 disposed on the first transmission rod 31 is elastically released, pushing the push member 33, the first fixing member 40 and the positioning assembly 4 to move forward synchronously (as shown in FIG. 1 ). Figure 5 As shown in FIG. 1 ). In this way, the second positioning portion 41 of the positioning component 4 can be separated from the first positioning portion 200 of the first tube body 20. When the second positioning portion 41 of the positioning component 4 is separated from the first positioning portion 200 of the first tube body 20, the clamping component 5 and the first handle 32 are coaxially rotatable. Therefore, the clamping component 5 rotates with the rotation of the first handle 32 (as shown in FIG. 1 ). Figure 6As shown), after the clamping assembly 5 is rotated to an appropriate position, the first handle 32 of the first quick release assembly 3 can be moved to the original position, so that the second positioning portion 41 of the positioning assembly 4 and the first positioning portion 200 of the first tube body 20 form a toothed positioning relationship (as shown in FIG. Figure 7 At the same time, the clamping assembly 5 cannot rotate with the rotation of the first handle 32. For example, if the clamping assembly 5 is to clamp the seat tube B1 of the bicycle B, the clamping assembly 5 is rotated to a horizontal position by rotating the first handle 32, and the seat tube B1 is clamped through the clamping space 52 (as shown in FIG. Figure 8 When the clamping assembly 5 is to clamp the upper tube B2 of the bicycle B, the first handle 32 can be rotated to rotate the clamping assembly 5 to a longitudinal position, and the upper tube B2 can be clamped through the clamping space 52 (as shown). Fig. 9 As shown). Also, the clamping assembly 5 can be controlled by the adjustment member 550 to swing the lower clamping portion 51 downward or upward by pulling the second handle 55 (as shown). Fig.10 and Fig.11 As shown), the size of the clamping space 52 is changed so that the clamping assembly 5 has a clamping effect capable of clamping different pipe diameters.
[0077] In other words, the technical means of the utility model is to pull the first handle 32 of the first quick-release component 3 to separate the first tube body 20 and the positioning component 4 from the original meshing positioning structure, and then use the first handle 32 and the clamping component 5 to form a coaxial rotating structure. Rotating the first handle 32 can achieve the effect of synchronously rotating the clamping component 5, thereby achieving rapid clamping and fixing and improving maintenance efficiency.
[0078] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
