[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.
[0026] As Figures 1 to 4 shown, the utility model provides a front control swing arm structure, including swing arm main body 1, swing arm main body 1's outside fixedly connected with connecting ring 2, the inside of connecting ring 2 is provided with bolt 3, swing arm main body 1's outside fixedly connected with butt joint lever 4, and connecting ring 2 is provided with connecting mechanism 5 between bolt 3;
[0027] Connecting mechanism 5 includes mounting hole 51, and the bottom of bolt 3 is fixedly connected with link disc 52, and the bottom of link disc 52 is fixedly connected with fixed rod 53, and the outside of bolt 3 is fixedly connected with L-shaped plate 54, and the outside of L-shaped plate 54 is fixedly connected with threaded tube 55, and the inside screw thread of threaded tube 55 is connected with screw rod 56, and the inside of L-shaped plate 54 is fixedly connected with return spring 57, and the outside of return spring 57 is fixedly connected with clamping block 58, and the outer wall of connecting ring 2 is provided with positioning groove 59.
[0028] Specifically, the outside of swing arm main body 1 is provided with moving mechanism 6, moving mechanism 6 includes top plate 61, and the top of top plate 61 is slidably connected with moving block 62, and the bottom of moving block 62 is fixedly connected with connecting rod 63, and the outside of moving block 62 is fixedly connected with extension plate 64, and the top of extension plate 64 is fixedly connected with movable tube 65, and the inside of movable tube 65 is movably connected with clamping rod 66, and the inside of top plate 61 is provided with No. 1 recess 67 and No. 2 recess 69, and clamping rod 66 is fixedly connected with compression spring 68.
[0029] As Figures 1 to 4 shown, mounting hole 51 is evenly distributed in the inner bottom wall of connecting ring 2, fixed rod 53 is evenly distributed at the bottom of link disc 52, and fixed rod 53 is matched with mounting hole 51, and the inside of mounting hole 51 is entered through fixed rod 53 at the bottom of link disc 52, so that bolt 3 is initially installed in the inside of connecting ring 2.
[0030] Further, screw rod 56 transversely passes through the inside of L-shaped plate 54, and return spring 57 is symmetrically distributed between clamping block 58 and L-shaped plate 54, and screw rod 56 is rotated in the inside of threaded tube 55, so that screw rod 56 moves on the outside of L-shaped plate 54.
[0031] As Figures 1 to 4As shown, one end of the screw 56 is located outside the snap-fit block 58, and the snap-fit block 58 is adapted to the positioning groove 59. The movement of the screw 56 pushes the snap-fit block 58, thereby causing the snap-fit block 58 to enter the interior of the positioning groove 59.
[0032] It is worth noting that the top plate 61 is fixedly connected to the top of the swing arm body 1, and the top plate 61 has a moving groove inside. The moving block 62 moves on the top of the top plate 61, thereby causing the connecting rod 63 to drive the docking rod 4 to move.

When the locking rod 66 enters the inside of the first groove 67 or the second groove 69, it can perform positioning processing on the moving block 62.
[0035] Working principle and process: By setting up the swing arm body 1, when it is necessary to replace the bolt 3 inside the connecting ring 2, the screw 56 is rotated, causing the screw 56 to move inside the L-shaped plate 54. When the screw 56 moves away from the locking block 58, the locking block 58 is moved out of the positioning groove 59 by the action of the return spring 57. Then, by moving the fixing rod 53 at the bottom of the connecting plate 52 out of the mounting hole 51 in the inner bottom wall of the connecting ring 2, the bolt 3 can be replaced. After replacing the new bolt 3, the screw 56 moves again to make the locking block 58 return to its original position. The bolt 3 can be easily replaced by entering the positioning groove 59. The swing arm body 1 is provided, and the docking rod 4 is provided on the outside of the swing arm body 1. When it is necessary to adjust the position of the docking rod 4, the bottom of the locking rod 66 is moved out of the first groove 67, and then the moving block 62 is moved on the top of the top plate 61, so that the connecting rod 63 drives the docking rod 4 to move. Then the locking rod 66 is released, and the locking rod 66 enters the second groove 69 under the action of the compression spring 68. At this time, the position of the docking rod 4 can be adjusted.
