[0005] Furthermore, the hook includes: a hook body, with several protrusions evenly distributed on the side of the top of the hook body.

[0006] Furthermore, the adapter block is provided with a first adapter hole, and the inner wall of the first adapter hole is provided with a through groove and a slot, the upper ends of the through groove and the slot being connected.

[0007] The protrusion is adapted to the through groove and the slot, and the hook is locked into the slot through the protrusion.

[0008] Furthermore, the protective cap has an auxiliary hole on its end face; a locking block is provided on the end face of the protective cap; the locking block is engaged in the through groove.

[0009] Furthermore, the support base is provided with a second transition hole that mates with the transition block; the second transition hole is a stepped hole; a first roller groove is provided at the step of the second transition hole, and a rolling element is rolled inside the roller groove.

[0010] Furthermore, the adapter block is provided with a second groove that mates with the rolling element.

[0011] Furthermore, the auxiliary hole is a threaded hole.

[0012] The advantages of this utility model compared with the prior art are:

[0013] The hook can be quickly installed and removed from the adapter block through a snap-fit ​​connection, eliminating the need to remove the clamping nut when replacing a traditional hook, simplifying the hook replacement process and enabling quick replacement of the hook on the main body.

[0026] 5. Main body. Detailed Implementation

[0027] like Figures 1-7 As shown, this embodiment is achieved through the following technical solution: a support base 4 is hinged to the lower end of the main body 5, and a transition block 2 for connecting the hook 1 is movably sleeved inside the support base 4. One end of the hook 1 is locked into the transition block 2, and a protective cap 3 is fastened on the transition block 2.

[0028] Specifically, the hook 1 includes a hook body 101, and a plurality of protrusions 102 are evenly distributed on the side of the top end of the hook body 101. In this embodiment, the number of protrusions 102 is two, such as... Figure 5 As shown.

[0029] Specifically, the adapter block 2 is provided with a first adapter hole 201, and the inner wall of the first adapter hole 201 is provided with a through groove 202 and a slot 203, the upper ends of the through groove 202 and the slot 203 are connected; the through groove 202 and the slot 203 are arranged along the axial direction of the first adapter hole 201.

[0030] The protrusion 102 is adapted to the through groove 202 and the slot 203, and the hook 1 is inserted into the slot 203 through the protrusion 102.

[0031] Specifically, the protective cap 3 has an auxiliary hole 302 on its end face; a locking block 301 is provided on the end face of the protective cap 3; the locking block 301 is engaged in the through groove 202. Specifically, the auxiliary hole 302 is a threaded hole.

[0032] In this embodiment, the protective cap 3 is magnetized and magnetically attached to the adapter block 2 to prevent it from falling off. When removing the protective cap 3, the operator uses a screw to screw into the auxiliary hole 302 and pulls the screw to remove the protective cap 3 from the adapter block 2.

[0033] Specifically, the support base 4 is provided with a second transition hole 402 that mates with the transition block 2; the second transition hole 402 is a stepped hole; a first roller groove is provided at the step of the second transition hole 402, and a rolling element 401 is rolled inside the roller groove.

[0034] Specifically, the adapter block 2 is provided with a second groove that cooperates with the rolling element 401.

[0035] The specific working principle of this utility model is as follows:

[0036] When installing hook 1, align the protrusion 102 with the through groove 202. The protrusion 102 slides along the through groove 202. After the protrusion 102 has passed through the through groove 202, rotate the hook body 101 to align the protrusion 102 with the locking groove 203 and engage it. At this point, hook 1 is properly engaged on the main body 5. When disassembling hook 1, move the hook body 101 to disengage the protrusion 102 from the locking groove 203. Rotate the hook body 101 to allow the protrusion 102 to slide into the through groove 202. Finally, the hook body 101 is disengaged along the through groove 202.

[0037] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
