The main body 10 is used for mounting the hook body 20. Combining with the appendix Figure 2 , the main body 10 includes a receiving groove 11 and a limiting groove 12. The receiving groove 11 is used for receiving the mounting arm 21 of the hook body 20. The limiting groove 12 communicates with the receiving groove 11. The main body 10 is provided with a fixing portion 30 for fixing the hook body 20. The fixing portion 30 includes a clamping member 31. The clamping member 31 cooperates with the limiting groove 12, and the clamping member 31 can contact the hook body 20 to detachably fix the hook body 20 into the receiving groove 11.

[0041] By opening a receiving groove 11 on the main body 10, the receiving groove 11 is used for mounting the mounting arm 21 of the hook body 20 to increase the contact area between the hook body 20 and the main body 10, which can play a role in installation positioning and reduce the difficulty of installation operation. By opening a limiting groove 12 communicating with the receiving groove 11 on the main body 10, the clamping member 31 cooperates with the limiting groove 12 so that the clamping member 31 can contact the hook body 20. The clamping member 31 is used to fix the hook body 20 to the main body 10, so that the mounting arm 21 will not come out of the receiving groove 11 during use, which can play a role in fixing the hook body 20 and improve the reliability of the tow.

[0042] As shown in the appendix Figure 2As shown, the hook body 20 includes a mounting arm 21, a connecting arm 22 and a traction arm 23. When the hook body 20 is installed on the main body 10, the mounting arm 21 and the traction arm 23 both extend along the Z direction, the connecting arm 22 is arranged between the mounting arm 21 and the traction arm 23, and the connecting arm 22 extends along the X direction, and the traction arm 23 is used to connect the traction rope.

[0043] Optionally, the mounting arm 21, the connecting arm 22 and the pulling arm 23 are all columnar members, such as cylindrical members.

[0044] Optionally, the mounting arm 21, the connecting arm 22 and the traction arm 23 are integrally formed.

[0045] Optionally, a ball head 231 is provided at the upper end of the traction arm 23, and the ball head 231 can limit the traction rope to ensure the traction quality.

[0046] In one example, as shown in the attached Figure 3 As shown, the main body 10 is also provided with a lock portion 40, which includes a lock body 41 and a stopper 42. One end of the lock body 41 is connected to the stopper 42. Figure 1 A locking groove 13 is provided on the main body 10, and the locking groove 13 is communicated with the receiving groove 11. The lock body 41 is movably installed in the locking groove 13, and can rotate around its own axis in the locking groove 13 to change the position of the limiting member 42 relative to the receiving groove 11. The limiting member 42 is used to cooperate with the mounting arm 21 to lock the mounting arm 21 into the receiving groove 11. When the locking portion 40 is in a locked state, the limiting member 42 is at least partially located in the receiving groove 11 to cooperate with the mounting arm 21 to achieve locking.

[0047] Optionally, a lock hole is provided on the lock body 41 , and the lock hole cooperates with a key, so that the lock body 41 can be rotated in the lock slot 13 by the key, thereby realizing locking or unlocking of the hook body 20 .

[0049] Embodiment 1

[0050] Combined with Figure 1 and attached Figure 2, the receiving groove 11 is opened at the lower end of the main body 10, the mounting arm 21 is mounted in the receiving groove 11 from bottom to top, the limiting groove 12 is opened on one side of the main body 10 and communicates with the receiving groove 11. The fixing part 30 includes the above-mentioned clamping part 31 and the reset part 32. The clamping part 31 is movably mounted in the limiting groove 12 through the reset part 32. One end of the clamping part 31 passes through the limiting groove 12 and enters the receiving groove 11, and can contact the mounting arm 21 to fix the mounting arm 21 in the receiving groove 11.

[0051] Optionally, the limiting groove 12 is opened on one side of the main body 10 in the X direction.

[0052] In one example, one end of the reset part 32 is fixedly arranged in the limiting groove 12, and the other end is connected to the clamping part 31. When the hook body 20 is mounted on the main body 10, the mounting arm 21 enters the receiving groove 11 from bottom to top. The mounting arm 21 contacts the clamping part 31, and the clamping part 31 is extruded. The reset part 32 generates elastic deformation and exerts an elastic force on the clamping part 31, so that the clamping part 31 has a tendency to move towards the side close to the mounting arm 21. The clamping part 31 can exert a force on the mounting arm 21 to realize the clamping and fixing of the mounting arm 21.

[0053] Optionally, the reset part 32 is a cylindrical spring.

[0054] In another example, as shown in the appendix Figure 3 shown, the fixing part 30 includes a connecting shaft 33. The connecting shaft 33 extends along the Y direction. A first shaft hole is opened on the clamping part 31, and the first shaft hole penetrates the clamping part 31 along the Y direction. A second shaft hole communicating with the limiting groove 12 is opened on the main body 10, and the second shaft hole penetrates the main body 10 along the Y direction. The first shaft hole and the second shaft hole cooperate with the connecting shaft 33, and the connecting shaft 33 passes through the first shaft hole and the second shaft hole. The clamping part 31 is movably mounted in the limiting groove 12 through the connecting shaft 33 and the reset part 32, and the clamping part 31 can rotate around the connecting shaft 33 in the limiting groove 12.

[0055] When the hook body 20 is not connected to the main body 10, one end of the clamping part 31 passes through the limiting groove 12 and is located in the receiving groove 11. The reset part 32 is not subjected to an external force. When installing the hook body 20, the mounting arm 21 enters the receiving groove 11 from bottom to top. When the mounting arm 21 contacts the clamping part 31, the clamping part 31 is extruded and rotates away from the mounting arm 21 around the connecting shaft 33. The reset part 32 is stressed and exerts a force on the clamping part 31, so that the clamping part 31 has a tendency to move towards the side close to the mounting arm 21. The clamping part 31 can exert a force on the mounting arm 21 to realize the clamping and fixing of the mounting arm 21.

[0056] Optionally, the reset part 32 is a torsion spring, a snap spring or other components that can provide elastic force. The reset part 32 is sleeved on the connecting shaft 33.

[0057] Optionally, two reset members 32 are provided and located on both sides of the clamping member 31 in the Y direction.

[0058] Optionally, in combination with Figure 1 and Figure 3 , both ends of the connecting shaft 33 pass through the second shaft hole on the main body 10, and fasteners 331 are provided at both ends of the connecting shaft 33. The connecting shaft 33 is fixed to the main body 10 through the fasteners 331. In an alternative embodiment, the connecting shaft 33 includes a threaded section and the fastener 331 is a nut.

[0059] In one example, in combination with Figure 2 and Figure 3 , a clamping groove 211 is formed at one end of the mounting arm 21 close to the clamping member 31. The clamping groove 211 cooperates with the clamping member 31. One end of the clamping member 31 passes through the limiting groove 12 and enters the receiving groove 11, and can be clamped in the clamping groove 211. The clamping groove 211 can increase the contact area between the clamping member 31 and the mounting arm 21, so that the mounting arm 21 can be stably installed in the receiving groove 11, reducing the risk of detachment and having good reliability. During the installation of the hook body 20, when the clamping member 31 enters the clamping groove 211, an assembled "click" sound will be generated, which can play a role in reminding that the installation is in place and is beneficial to improving the use experience.

[0060] Through the setting of the fixing portion 30, when disassembling the hook body 20, only an external force needs to be applied to the clamping member 31 to separate it from the mounting arm 21 or the clamping groove 211, and then the hook body 20 is pulled downward to remove the hook body 20 from the main body 10. No specific tool is required for disassembly and assembly, the operation is simple and convenient, and the installation is stable and firm.

[0061] Exemplarily, as shown in Figure 3 , a locking portion 40 is provided on the main body 10. In combination with Figure 1 , a locking groove 13 cooperating with the lock body 41 is formed on the main body 10. The locking groove 13 is formed above the receiving groove 11 and communicates with the receiving groove 11. Optionally, the locking groove 13 is formed in the main body 10 along the Y direction.

[0062] When the locking portion 40 is in the locked state, the limiting member 42 is completely received in the receiving groove 11 and contacts the upper end of the mounting arm 21. The limiting member 42 can apply a downward force to the mounting arm 21 to fix the clamping member 31 in the clamping groove 211 and prevent it from coming out, thereby realizing the locking of the mounting arm 21;

[0063] When the locking part 40 is in the unlocked state, the limiting part 42 rotates with the lock body 41 to be out of contact with the upper end of the mounting arm 21. At this time, there is a movable space at the upper end of the receiving groove 11, and the mounting arm 21 can be pushed upward to disengage the engaging part 31 from the card slot 211. Rotate the mounting arm 21 to misalign the position of the card slot 211 with the engaging part 31 in the X direction, and then pull the hook body 20 downward to remove the hook body 20 from the main body 10. The hook body 20 can be stored in the vehicle for storage and waiting to be used next time. The structure is simple and the disassembly and assembly are convenient.

[0064] Embodiment 2

[0065] Combined with the attached Figure 4 and the attached Figure 5 , the receiving groove 11 is opened at the lower end of the main body 10, the mounting arm 21 penetrates through the receiving groove 11 from bottom to top, the limiting groove 12 is opened on one side of the main body 10 in the X direction and penetrates through one side of the main body 10 in the Y direction. The limiting groove 12 is communicated with the receiving groove 11. The connecting arm 22 of the hook body 20 is installed in the limiting groove 12. The engaging part 31 is arranged on one side of the main body 10 in the Y direction and is located on one side where the limiting groove 12 penetrates through the main body 10 in the Y direction. The engaging part 31 extends along the Z direction, and the height dimension of the engaging part 31 in the Z direction is smaller than the height dimension of the limiting groove 12 in the Z direction, so that the engaging part 31 and the limiting groove 12 cooperate to form an opening 121 in the Y direction. The opening 121 cooperates with the connecting arm 22, and the connecting arm 22 can enter the limiting groove 12 through the opening 121. The engaging part 31 is used to contact the connecting arm 22 to cooperate with the limiting groove 12 to limit the connecting arm 22 in the Y direction to prevent the hook body 20 from falling off the main body 10.

[0066] When installing the hook body 20, rotate the hook body 20 so that the extending direction of the connecting arm 22 forms a certain angle with the X direction, and the connecting arm 22 does not interfere with the engaging part 31. Install the mounting arm 21 into the receiving groove 11 from bottom to top, and then rotate the mounting arm 21 so that the connecting arm 22 enters the limiting groove 12 through the opening 121. At this time, the connecting arm 22 extends along the X direction, and the installation of the hook body 20 is completed. The hook body 20 is accommodated in the limiting groove 12 under its own gravity. The disassembly and assembly can be realized without the aid of specific tools. The operation is simple and convenient, and the installation is stable and firm.

[0067] Optionally, the engaging part 31 cooperates with the limiting groove 12 and is installed with an interference in the Y direction with the connecting arm 22 to complete the clamping and fixing of the connecting arm 22.

[0068] Optionally, the engaging part 31 is integrally formed with the main body 10.

[0069] As shown in the attached Figure 5As shown, an elastic member 212 is provided at the upper end of the mounting arm 21. One end of the elastic member 212 is connected to the mounting arm 21, and the other end is a free end. When the mounting arm 21 is mounted in the receiving groove 11 from bottom to top, the elastic member 212 is compressed by force and applies a downward elastic force to the mounting arm 21. When the connecting arm 22 is received in the limiting groove 12, under the action of the elastic member 212, the connecting arm 22 is fixed in the limiting groove 12, which can prevent the connecting arm 22 from disengaging from the limiting groove 12.

[0070] Exemplarily, as shown in the attached Figure 4 As shown, a locking portion 40 is provided on the main body 10. A locking groove 13 that cooperates with the lock body 41 is formed on the main body 10. The locking groove 13 is formed in the main body 10 along the Y direction and is located on one side of the receiving groove 11. A function groove 14 communicating with the locking groove 13 is formed in the receiving groove 11. The function groove 14 is formed along the X direction. The function groove 14 is used to receive the limiting member 42. The lock body 41 is rotatably mounted in the locking groove 13 around its own axis. The limiting member 42 can rotate in the function groove 14 around the axis of the lock body 41. When the locking portion 40 is in the locked state, one end of the limiting member 42 passes through the function groove 14 and enters the receiving groove 11 and is located at the lower end of the mounting arm 21, which can play a blocking role and prevent the mounting arm 21 from being taken out of the receiving groove 11. When the locking portion 40 is in the unlocked state, the limiting member 42 is completely received in the function groove 14, and the mounting arm 21 can be taken out of the receiving groove 11.

[0071] Optionally, when the locking portion 40 is in the locked state, the limiting member 42 contacts the lower end of the mounting arm 21. The limiting member 42 cooperates with the elastic member 212 to fix the mounting arm 21 in the Z direction to prevent the mounting arm 21 from disengaging from the receiving groove 11. When unlocking, the lock body 41 is rotated by a key to make the limiting member 42 rotate downward until it is received in the function groove 14.

[0072] Optionally, when the locking portion 40 is in the locked state, the limiting member 42 does not contact the lower end of the mounting arm 21, and the limiting member 42 only plays a blocking role. When unlocking, the lock body 41 is rotated by a key to make the limiting member 42 rotate upward or downward until it is received in the function groove 14. In a preferred solution, as shown in the attached Figure 4 As shown, in the locked state, since the limiting member 42 does not contact the lower end of the mounting arm 21, there is a gap between the upper end of the limiting member 42 and the lower end of the mounting arm 21. Therefore, the limiting member 42 is configured to rotate upward when unlocking. With this setting, the space occupied by the function groove 14 in the Z direction on the main body 10 can be reduced, which is beneficial to reducing the overall size of the main body 10 and further improving the lightweight effect.
