In this embodiment, the chucking part 3092 includes a plurality of gear teeth (not shown) arranged in a circumferential direction of the chuck 309 on one end surface of the chuck 309; it is understood that in other embodiments, the securing portion 3092 can have other configurations, such as the securing portion 3092 can be formed by a plurality of spaced apart protrusions.

When assembled, the chuck 309 is secured to the carrier 308. The optical axis 3082 of the carrier 308 sequentially passes through one damping member 305, the first connecting body 306, one damping member 305, the retainer ring 304 and the nut 303, so that the optical axis 3082 is connected to the two damping members 305, the first connecting body 306, the retainer ring 304 and the nut 303. The threaded shaft 3022 of the connector 302 is threaded through the third through hole 3084 of the carrier 308 to couple with the carrier. The nut 303 is partially received in the second receiving groove 3023 of the connector 302, and the connector 302 and the nut 303 are not screwed together. The retainer ring 304 is supported against one side of the first connecting body 306 by the corresponding damping member 305. The carrier 308 supports the corresponding damping member 305 against the other side of the first connecting body 306. The two engagement surfaces 3083 are engaged with the inner ring hole 3041 to limit the rotation of the retainer ring 304 around the optical axis 3082, thereby preventing the nut 303 from loosening.

The link 301 is fixed to the first connecting body 306, and the knob 3021 of the link 302 is partially received in the receiving portion 3016 of the link 301. The second elastic element 307 is partially accommodated in the two first accommodating grooves 3015 and the third accommodating groove 3063, and the second elastic element 307 is connected to the connecting portion 301 and the first connecting body 306.

It is understood that in other embodiments, the damping member 305 may be provided on the catch 10.

Referring to fig. 4, a cradle head 200 according to a second embodiment of the present invention includes a main body 201 and the clamping structure 100 connected to the main body 201, where the main body 201 is the above-mentioned carrying member. The threaded shaft 3022 of the connector 302 of the clamp structure 100 is threadedly coupled to the body 201. The main body 201 includes an engaging portion 2011, and the engaging portion 2011 abuts against the fastening portion 3092 of the chuck 309 of the clamping structure 100, so that the chuck 309 is connected to the main body 201. In the present embodiment, the engaging portion 2011 is a disk tooth.

Referring to fig. 5, when the holder 200 holds an object (not shown), one end of the object is supported against the second elastic member 307 of the holding structure 100. According to the distance between the end of the object abutting against the second elastic member 307 and the other end opposite to the end, the clamping part 10 is pulled to adjust the distance between the second elastic member 307 and the clamping member 6, the tension spring 2 is elastically deformed, and the bottom case 1, the tension spring 2, the bottom plate 4, the connecting arm 5, the clamping member 6, the first elastic member 7 and the bearing plate 8 are gradually far away from the second elastic member 307 along the length direction of the guide groove 31 of the guide member 3; meanwhile, the two clamping members 6 rotate around the two second connecting posts 43 of the bottom plate 4, respectively, so that the two clamping members 6 and the second elastic member 307 clamp the object together. Two corners of one end of the object are respectively received in the two receiving slots 64 of the clamping member 6, so that the object is prevented from sliding out of the clamping structure 100 when being vibrated.

When the object needs to change the angle, an external force is applied to the clamping structure 100 to overcome the rotation resistance provided by the two damping members 305 to the rotation of the holding part 10 around the optical axis 3082 of the supporting body 308 relative to the main body 201, so that the clamping structure 100 is in a rotation state, and the holding part 10 can rotate to any angle relative to the adapter part 30. When the external force disappears after the object is rotated to a desired angle, the holding structure 100 is in a locked state, and the rotational resistance maintains the holding part 10 at an arbitrary angle with respect to the main body 201.

When the object needs to be removed from the holding structure 100, the holding part 10 slides in a direction away from the main body 201 to move away from the main body 201, and the object is taken out from the holding structure 100. The catching part 10 is restored to the original position by the elastic force of the tension spring 2.

Referring to fig. 6, when the pan/tilt head 200 is not in use, the two clamping members 6 rotate towards the bottom shell 1 around the second connecting column 43 of the bottom plate 4, so that the two clamping members 6 and the two connecting arms 5 are respectively and partially accommodated in the two first accommodating grooves 42 of the bottom shell 1. The retaining part 10 rotates towards the main body 201 relative to the adapter part 30, so that the retaining part 10 is close to the main body 201, and the main body 201 is opposite to the retaining part 10, thereby facilitating the storage of the holder 200.

Referring to fig. 7 to 9, the clamping structure 300 according to the third embodiment of the present invention is substantially the same as the clamping structure 100 according to the first embodiment of the present invention, except that two damping members 305 are omitted from the clamping structure 300, and the nut 303, the retaining ring 304 and the carrier 308 are omitted from the adapting portion 40 of the clamping structure 300. The adapter 40 further includes an elastic body 401, a spring 402 and a support member 403. The supporting member 403 has a receiving hole 4031.

The clamping part 10 is connected to the adapter part 40.

One end of the elastic body 401 is connected to the bottom surface of the second receiving groove 3023 of the connecting member 302, and the other end is connected to the surface of the abutting member 403 opposite to the first connecting body 306. The clamp spring 402 is disposed on the threaded shaft 3022, the chuck 309 abuts against the clamp spring 402, and the clamp spring 402 is used for preventing the chuck 309 from moving along the axial direction of the threaded shaft 3022. The connecting portion 301 is fixedly connected to the first connecting body 306, and the connecting member 302 is partially received in the receiving portion 3016 of the connecting portion 301. The second elastic element 307 is connected to the connecting portion 301 and the first connecting body 306.

Referring to fig. 10, a cradle head 400 according to a fourth embodiment of the present invention is substantially the same as the cradle head 200 according to the second embodiment of the present invention, except that the holding structure 100 is omitted from the cradle head 400, and the cradle head 400 further includes the holding structure 300. The threaded shaft 3022 of the connector 302 of the clamp structure 300 is threadedly coupled to the body 201. The chuck 309 can be clamped to the main body 201 to limit the adapter 40 from loosening relative to the main body 201. The engaging portion 2011 of the main body 201 of the holder 400 abuts against or disengages from the fastening portion 3092 of the chuck 309 of the clamping structure 300, so that the clamping structure 300 is in a locked state or a rotatable state, and the rotation of the clamping structure 300 is realized or the clamping structure 300 is limited to any stop position.

When the object held by the holding structure 300 needs to change the angle, the elastic body 401 is elastically deformed by an external force, the chuck 309 is in a movable state, and slides in a direction away from the main body 201 to disengage from the main body 201, and the holding structure 300 is in a rotating state, and the holding structure 300 can rotate to any angle relative to the main body 201. When the external force disappears after the object is rotated to a desired angle, the elastic body 401 is deformed, the chuck 309 is restored to the original position by the elastic force of the elastic body 401 through the abutting member 403, and is in the locked state, the clamping portion 3092 of the chuck 309 abuts against the engaging portion 2011 of the main body 201, so that the holding structure 300 is held at an arbitrary angle with respect to the main body 201, and the holding structure 300 is in the locked state.
