Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1

[0037] Reference Figure 1 , which is the first embodiment of the utility model, provides a chuck that is easy to disassemble, including a fixing rod 100 and a mounting head 200. Through the cooperation between the fixing rod 100 and the mounting head 200, the mounting head 200 can be quickly installed, which can effectively improve the overall work efficiency.

[0038] Specifically, the fixing rod 100 includes a movable groove 101 arranged inside the fixing rod 100, a linkage member 102 arranged inside the movable groove 101, and a clamping pile 103 abutting against the linkage member 102. The outer wall of the fixing rod 100 is also provided with a connecting groove 104 and an unlocking member 105. The setting of the linkage member 102 is used to control the clamping pile 103 to reach a locking state with the clamping groove 201, and the setting of the unlocking member 105 can effectively achieve quick disassembly.

[0039] Furthermore, the mounting head 200 includes a slot 201 that fits in with the locking post 103 d . The end of the slot 201 is slightly curved to assist the locking post 103 d in being embedded.

[0040] Usage process: The staff inserts the installation head 200 by rotating the fixing rod 100, and the installation head 200 will move with the linkage member 102, thereby releasing the restriction on the clamping pile 103, so that the clamping pile 103 can bounce into the clamping slot 201, forming a locked state.

[0041] Example 2

[0042] Reference Figures 1 to 11, which is the second embodiment of the utility model. Different from the previous embodiment, it also includes a linkage member 102 including a first spring 102a fixedly connected to the inner wall of the movable groove 101, and a moving pile 102b fixedly connected to the first spring 102a, one end of the moving pile 102b protrudes from the movable groove 101, and the other end of the moving pile 102b is wedge-shaped and extends toward the clamping pile 103. The moving pile 102b is annularly arranged along the inner wall of the fixed rod 100, and the moving pile 102b is When the installation head 200 just enters the interior of the fixing rod 100, it will not contact the installation head 200 until the slot 201 is about to reach the position of the clamping pile 103. At this time, the movable pile 102b is pushed by the installation head 200 to continue to go deeper, and then it will abut against the limiting pile 102c, so that the limiting pile 102c is away from the clamping pile 103. At this time, the clamping pile 103 is no longer restricted by the limiting pile 102c, and under the action of the third spring 103a, the clamping pile 103 will immediately bounce into the slot 201.

[0043] Preferably, the linkage member 102 also includes a limiting pile 102c arranged on one side of the movable pile 102b, the limiting pile 102c is fixedly connected to the inner wall of the movable groove 101 through a second spring 102d, the limiting pile 102c is arranged directly below the clamping pile 103, and the side of the limiting pile 102c abuts against the movable pile 102b.

[0044] Preferably, the card pile 103 includes a third spring 103a fixedly connected to the inner wall of the movable groove 101, and an auxiliary groove 103b is further provided on the side of the card pile 103 facing the movable pile 102b, and a fourth spring 103c is provided in the auxiliary groove 103b. A locking pile 103d fixedly connected to the fourth spring 103c is provided, and the end of the locking pile 103d is wedge-shaped, and the side of the locking pile 103d is wedge-shaped. The bottom of the card pile 103 is also provided with an unlocking groove 103d-1. When the card pile 103 enters the card slot 201, the locking pile 103d will first contact the end of the card slot 201, and the fourth spring 103c acts to cause the locking pile 103d to contract. In the process of continuing to descend, when the locking pile 103d moves to the locking slot 201a position, the fourth spring 103c rebounds, so that the locking pile 103d is embedded in the locking slot 201a, and complete positioning can be achieved at this time.

[0045] Preferably, a fifth spring 104 a is disposed inside the connection slot 104 . The connection slot 104 corresponds to the position of the movable pile 102 b , and the connection slot 104 extends all the way through to the position of the clamping pile 103 .

[0046] Preferably, the unlocking member 105 includes a rotating sleeve 105a fixedly connected to the fifth spring 104a, the surface of the rotating sleeve 105a is provided with an anti-slip groove 105a-1, and the rotating sleeve 105a is also provided with an unlocking column 105a-2 extending toward the locking pile 103, and the unlocking column 105a-2 is abutted and matched with the locking pile 103d.

[0047] Preferably, a locking groove 201 a which is embedded and matched with the locking post 103 d is provided on one side of the locking groove 201 , and an inclined block 201 b which is abutted and matched with the unlocking groove 103 d - 1 is also provided inside the locking groove 201 .

[0048] Preferably, the rotation direction of the mounting head 200 is opposite to the rotation direction of the rotating sleeve 105a.

[0049] Usage process: the staff will align the installation head 200 with the direction of the fixed rod 100 and insert it. The moving pile 102b is pushed by the installation head 200 to continue to go deeper, and then it will abut against the limiting pile 102c, so that the limiting pile 102c is away from the clamping pile 103. At this time, the clamping pile 103 is no longer restricted by the limiting pile 102c. Under the action of the third spring 103a, the clamping pile 103 will immediately rebound into the clamping groove 201. When the clamping pile 103 enters the clamping groove 201, the locking pile 103d will first contact the end of the clamping groove 201. The fourth spring 103c acts to make the locking pile 103d shrink. In the process of continuing to descend, when the locking pile 103d moves to the locking groove 201a position, the fourth spring 103c rebounds, so that the locking pile 103d is embedded in the locking groove 201a. At this time, complete positioning can be achieved;

[0050] When unlocking is required, the staff rotates the rotating sleeve 205a and the installation head 200 at the same time. At this time, the rotating sleeve 205a will bring the unlocking column 105a-2 to abut against the side of the locking pile 103d, so that the locking pile 103d can be pushed to shrink into the auxiliary groove 103b. At this time, due to the abutment between the unlocking groove 103d-1 and the inclined block 201b, the pile 103 will be pushed out of the groove 201, and then the installation head 200 and the fixing rod 100 can be separated from each other.

[0051] It should be noted that, whether the locking pile 103d is in the initial state or is pushed into the locking slot 201a, the locking pile 103d does not interact with the unlocking column 105a-2. Only when the rotating sleeve 205a is rotated can the locking pile 103d be driven to contract. After the locking state is released, due to the action of the fifth spring 104a and the fourth spring 103c, the rotating sleeve 205a and the locking pile 103d will return to the initial state.

It includes a pulling assembly 300, including a main rod 301 fixedly connected to the fixed rod 100, and the main rod 301 is connected to the hydraulic pump through a hydraulic pipe 302

[0054] Furthermore, the main rod 301 pulls the fixed rod 100 through the piston action.

[0055] Usage process: turn on the hydraulic pump and transmit power to the main rod 301 through the hydraulic pipe 302. A piston is arranged inside the main rod 301, which will pull the fixing rod 100 and the installation head 200 as a whole to perform the pin pulling action.
