[0022] The present utility model provides a technical solution: As Figures 1-4As shown in the figure, in this embodiment, a loosening-proof tool chuck includes: a fixing mechanism 1, the fixing mechanism 1 includes a base 11, a chuck body 12 is arranged on the top of the base 11, four positioning grooves 13 are annularly and arrayedly formed on the outer surface of the chuck body 12, four fixing blocks 15 are annularly and arrayedly arranged on the top of the base 11, a dial block 16 is arranged on one side of the four fixing blocks 15 away from the chuck body 12, the bottom of the chuck body 12 is fixedly connected to the top of the base 11, the bottom of the fixing block 15 is fixedly connected to the top of the base 11, one side of the dial block 16 is in contact with the side of the fixing block 15 away from the chuck body 12, movable rods 17 are arranged inside the fixing blocks 15, return springs 18 are arranged outside the four movable rods 17, a clamping block 19 is arranged at one end of the four movable rods 17 away from the dial block 16, a fixing member 110 is arranged in the threaded groove formed in the fixing block 15, a tool shank 111 is arranged inside the chuck body 12, four connecting rods 112 are annularly and arrayedly arranged on the outer surface of the tool shank 111, one end of the movable rod 17 is movably connected to the inside of the dial block 16, the other end of the movable rod 17 penetrates through the inner ring of the return spring 18 and is fixedly connected to the end of the clamping block 19 away from the connecting rod 112, one end of the return spring 18 is fixedly connected to the inner wall of the fixing block 15 away from the chuck body 12, fixing grooves 113 are formed at one ends of the four connecting rods 112 away from the chuck body 12, the other end of the return spring 18 is fixedly connected to the end of the clamping block 19 away from the connecting rod 112, the end of the clamping block 19 away from the return spring 18 is clamped in the fixing groove 113, one end of the tool shank 111 is inserted into the chuck body 12, one end of the connecting rod 112 is fixedly connected to the outer surface of the tool shank 111, the outer surface of the connecting rod 112 is slidably connected to the inner wall of the positioning groove 13, the end of the connecting rod 112 away from the tool shank 111 is butted in the clamping groove formed in the fixing block 15, one end of the fixing frame passes through the threaded groove on one side of the fixing block 15 and is threadedly connected to the inner wall of the threaded groove formed on one side of the connecting rod 112, and an auxiliary mechanism 2 is arranged at the top end of the chuck body 12.
[0023] In this embodiment, when the staff needs to fixedly install the tool on the tool head of the tool holder, the staff can move the dial block 16. Then, the dial block 16 will be squeezed and rubbed against the fixed block 15 to drive the movable rod 17 and the clamping block 19 to move. When the clamping block 19 moves, it will squeeze the return spring 18, and then the return spring 18 will contract and deform. The staff can insert the tool rod 111 into the chuck body 12, and then the connecting rod 112 will also be butted in the positioning groove 13. When the tool rod 111 is inserted into the bottom end of the chuck body 12, the end of the connecting rod 112 away from the tool rod 111 will be butted in the clamping groove opened in the fixed block 15. Then, the staff rotates the fixing member 110 clockwise to threadedly connect it in the threaded grooves opened in the fixed block 15 and the connecting rod 112. Therefore, the connecting rod 112 and the tool rod 111 will be limited and fixed. The staff puts down the dial block 16, and the return spring 18 will lose the extrusion force and then release the elastic force to push the clamping block 19 into the fixing groove 113. Therefore, the connecting rod 112 and the tool rod 111 will be secondarily fixed and limited, avoiding the phenomenon of loosening between the tool rod 111 and the chuck body 12 during long-term use of the tool.
[0024] As Figure 1 and Figure 4 shown, the auxiliary mechanism 2 includes a reinforcing ring 21. The inner surface of the reinforcing ring 21 is provided with a threaded portion 22, and the threaded portion 22 is threadedly connected to the threaded groove opened on the outer surface of the top end of the chuck body 12. The outer surface of the reinforcing ring 21 is fixedly connected with an anti-slip pad 23.
[0025] In this embodiment, the threaded portion 22 of the reinforcing ring 21 is threadedly connected to the threaded groove at the top end of the chuck body 12, so as to clamp the top end of the chuck body 12. Therefore, the connection between the outer surface of the tool rod 111 and the top end of the chuck body 12 will have an effective fixing effect. In addition, the anti-slip pad 23 provided on the outer surface of the reinforcing ring 21 can provide an anti-slip function, avoiding the phenomenon of slipping when the reinforcing ring 21 is screwed.
[0026] The present utility model provides an anti-loosening tool chuck, and the specific working principle is as follows:
[0027] When the staff needs to firmly install the tool on the tool head of the tool holder, the staff can move the dial block 16 to generate extrusion friction between the dial block 16 and the fixed block 15, thereby driving the movement of the movable rod 17 and the chuck 19. During this process, the chuck 19 will exert pressure on the return spring 18, causing the return spring 18 to deform and contract. Next, the staff can insert the tool bar 111 into the chuck body 12, and at the same time, the connecting rod 112 will also be docked in the positioning groove 13. When the tool bar 111 is inserted to the bottom end of the chuck body 12, the end of the connecting rod 112 away from the tool bar 111 will be docked in the card slot opened on the fixed block 15. In order to further fix the connecting rod 112 and the tool bar 111, the staff can rotate the fixing member 110 clockwise and thread it into the thread grooves opened on the fixed block 15 and the connecting rod 112. The connecting rod 112 and the tool bar 111 will be limited and fixed to ensure that they will not loosen during use. Then the staff can put down the dial block 16, which causes the return spring 18 to lose the extrusion pressure and then release the elastic force to push the chuck 19 into the fixing groove 113. The connecting rod 112 and the tool bar 111 will be secondarily fixed and limited. The staff can thread the threaded portion 22 of the reinforcement ring 21 with the thread groove at the top end of the chuck body 12, and the connection between the outer surface of the tool bar 111 and the top end of the chuck body 12 will obtain an effective clamping effect.
[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made in these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
