[0036] In addition, the button 9 is arranged on the side of the chuck 3 close to the handle 6, the button 8 is pushed to release the locking state of all second rods 5 when the handle 6 is moved.

[0037] Each second rod 5 comprises a second support rod 13 and a rotating shaft 14, each rotating shaft 14 is rotatably connected to the lower surface of the chuck 3, each second support rod 13 is fixedly connected with the corresponding rotating shaft 14 at an angle and can rotate with the rotating shaft 14 to the unfolded or folded state.

[0038] The rotating shaft 14 comprises a rotating shaft part 15 rotatably connected with the chuck 3 and a fixed part 16 fixedly connected with the rotating shaft part 15 at an angle, the second support rod 13 is fixedly connected with the fixed part 16, and the fixed part 16 can be clamped with the clamping block 10.

[0039] 0038.The lower surface of the chuck 3 is provided with a plurality of through holes 17 corresponding to the plurality of clamping blocks 10, and the fixing portion 16 is provided with a hook portion 18 which can pass through the through hole 17 and be clamped with the clamping block 10.

[0040] When the chuck assembly 1 is operated, the fingers hold the handle 6 and the button 9 and press them with force, so that the button 9 moves towards the handle 9, thereby releasing the locking state of the locking mechanism. The shape of the button 9 can be annular or baffle-shaped, and of course other shapes can also be provided according to the needs.

[0041] A strip-shaped slot 19 is formed on each clamping block 10, and a protruding column 20 corresponding to the number of clamping blocks 10 is arranged on the push plate 8 and is connected in the strip-shaped slot 19. The elastic member 11 pushes the clamping block 10 to move forward, and the strip-shaped slot 19 on the clamping block 10 also pushes the protruding column 20, so that the push plate 8 also moves to the final position, and the locking mechanism is in the locked state. If one or more clamping blocks 10 are pushed to move backward by external force, the clamping block 10 will not affect the push plate 8 due to the space in the strip-shaped slot 19, and each clamping block 10 can be locked independently. When unlocking, the push plate 8 is pulled to move backward, and each protruding column 20 pushes the corresponding clamping block 10 to move backward through the strip-shaped slot 19, so that all clamping blocks 10 are unlocked at the same time.

[0042] The clamping block 10 is provided with an inclined surface 21, and when the second rod member 5 is flipped to contact the inclined surface 21 of the clamping block 10, the clamping block 10 is pushed to move backward, and after the second rod member 5 is unfolded, the elastic member 11 pushes the clamping block 10 to move forward and reset, thereby blocking and locking the second rod member 5. When the second rod member 5 includes a second supporting rod 13 and a rotating shaft member 14, the clamping block 10 can block the second supporting rod 13 or the rotating shaft member 14, and both can achieve blocking and locking.

[0043] The second rod member 5 is flipped when unfolded and folded. To ensure that the second rod member 5 is unfolded around the chuck 3 when unfolded, and can be folded on the lower surface of the chuck 3 when folded, each rotating shaft member 14 is rotatably connected to the lower surface of the chuck 3, and each second supporting rod 13 is fixedly connected to the corresponding rotating shaft member 14 at an angle, and the second supporting rod 13 can rotate with the rotating shaft member 14 to an unfolded or folded state. The left and right second rod members 5 are in a left-right symmetrical state. Specifically, the angle between each second supporting rod 13 and the corresponding rotating shaft member 14 is different, which ensures that the second supporting rod 13 is unfolded around the chuck 3 when unfolded, and can be stretched downward when folded, so that the second supporting rods 13 can be folded together.

[0044] Referring to FIG. 6, another embodiment of the hand pulling member 12 is provided with a handle 22 in the middle.

[0045] Each side of the hand-pulling piece 12 is fixedly connected with a second rod piece 5, and the middle part of the hand-pulling piece 12 can cross at most four second rod pieces 5.

[0046] Referring to Fig. 7, another embodiment of the hand-pulling piece 12 is composed of three strip-shaped bodies 23 which are hingedly or universally connected end to end, and the strip-shaped bodies 23 at two sides are respectively hingedly connected with corresponding second rod pieces 5.

[0047] Referring to Figs. 8-11, another embodiment of the chuck assembly 1 is that the button 9 is hingedly connected at the inner end in the chuck 3 with the chuck 3, and the outer end of the button 9 outside the chuck 3 is a finger pressing part, the push plate 8 is in abutment with the button 9, and the push plate 8 is pushed by the rotation of the button 9 to unlock the locking mechanism, and the distance from the abutment position of the push plate 8 and the button 9 to the hinge position of the button 9 is less than the distance from the finger pressing part to the hinge position of the button 9.

[0048] Referring to Fig. 9, when unlocking, the moving direction of the push plate 8 is consistent with the rotating direction of the finger pressing part, as shown in Fig. 9, when unlocking, the finger pressing part of the button 9 is rotated to the right and approaches the handle 6, which will drive the push plate 8 to move to the right at the same time. As shown in Fig. 9, the clamping part of the chuck block 10 for clamping the rod piece is located at the left side of the chuck block 10, at this time, the right movement is required to realize the unlocking. The button 9 is provided with a pushing surface, and the push plate 8 is provided with a pushed surface, the pushed surface is in abutment with the pushing surface, and the abutment position of the pushed surface and the pushing surface is located between the hinge position of the finger pressing part and the button 9.

[0049] The bottom surface of the button 9 of Fig. 9 is provided with a first protrusion 24, and the outer side of the push plate 8 is provided with a second protrusion 25, here, the inside is close to the center of the chuck 3, and the outside is far away from the center of the chuck 1. The opposite sides of the first protrusion 24 and the second protrusion 25 are respectively the pushing surface and the pushed surface, under the action of the elastic member 11, the push plate 8 will keep close to the button 9, so that the pushed surface of the second protrusion 25 and the pushing surface of the first protrusion 24 keep in abutment. When the button 9 rotates, the pushing surface and the pushed surface transmit the pushing force to push the push plate 8, and in this process, the pushing surface and the pushed surface will produce relative displacement. The abutment position of the pushed surface and the pushing surface is located between the hinge position of the finger pressing part 26 and the button 9, so that the distance from the abutment position to the hinge position is less than the distance from the finger pressing part 26 to the hinge position, which ensures the labor-saving of the unlocking operation.

[0050] Referring to Fig. 11, in another embodiment, the moving direction of the push plate 8 is opposite to the rotating direction of the finger pressing part when unlocking. When unlocking, the finger pressing part of the pressing button 9 rotates to the right and moves towards the handle 6, which will drive the push plate 8 to move to the left at the same time. As shown in Fig. 11, the clamping part of the clamping block 10 for clamping the rod member is located at the right side of the clamping block 10, which needs to move to the left to achieve unlocking at this time.

[0051] The inner end of the button 9 of Fig. 11 extends to the inner side of the chuck 3 beyond the inner side surface of the push plate 8. A first protrusion 24 is arranged on the bottom surface of the button 9, and a second protrusion 25 is arranged on the outer side of the push plate 8. Here, the inner side is close to the center of the chuck 3, and the outer side is away from the center of the chuck 1. The opposite sides of the first protrusion 24 and the second protrusion 25 are the pushing surface and the pushed surface respectively. Under the action of the elastic member 11, the push plate 8 will keep close to the button 9, so that the pushed surface of the second protrusion 25 and the pushing surface of the first protrusion 24 keep abutting contact. The hinge of the button 9 is located between the abutting position of the pushed surface and the pushing surface and the finger pressing part 26, so that when the finger pressing part 26 rotates to the right, the abutting position moves to the left. In addition, the distance from the abutting position to the hinge is less than the distance from the finger pressing part 26 to the hinge, which ensures the labor-saving of the unlocking operation.

[0052] The finger pressing part 26 is provided with an inner concave arc surface on the side surface for finger contact and pressing. When operating, the inner concave arc surface can be in close contact with the finger, so that the pressing is more comfortable.

[0053] Because of the superimposed elastic force of the plurality of elastic members 11 and the elastic force generated by the deformation of the first rod member 4 and the second rod member 5 after unfolding when unlocking, the moving friction of the clamping block 10 and the push plate 8 increases, which results in that the resistance when unlocking the pressing button 9 will greatly increase. Because the button 3 and the push plate 2 of the chuck assembly of Figs. 2-5 often adopt a fixed connection structure, when the button 3 is pressed, a phenomenon of large resistance and unlocking not smooth will appear, so the improved structure of the chuck assembly shown in Figs. 8-11 can solve the problem of large resistance and unlocking not smooth when unlocking.

[0054] That is, the button 9 and the push plate 8 are designed as a separated structure, the button 9 is hinged to the inner end of the chuck 3 and the outer end of the chuck 3 is the finger pressing part, so that the push plate 8 abuts against the button 8. At the same time, the distance from the abutting position of the push plate 8 and the button 9 to the hinge of the button 9 is less than the distance from the finger pressing part to the hinge of the button 9, so that when the finger pressing part 26 is pressed, the button 9 will be rotated with smaller force, which helps to overcome the resistance and more smoothly drive the push plate 8 to move and drive the clamping block 10 to unlock.

[0055] Referring to Fig. 12, when unfolding the soft light box, in the state shown in Fig. 1, the tail of the first rod 4 and the second rod 5 is grounded, then the hand pull 12 is pulled to open the two rods by a certain angle, and then the handle 6 is pressed down by hand, the first rod 4 and the second rod 5 of the chuck assembly 1 are unfolded, thereby driving the soft light cloth 2 to unfold, when the handle 6 is pressed down to the position, the clamping assembly 7 on the chuck 3 will lock all the second rods 5, so that the unfolded state of the soft light box is fixed, then the soft light box can be installed on the professional lighting lamp through the installation cylinder 27 on the upper surface of the chuck 3 for use; when the soft light box is folded after use, the soft light box is removed from the professional lighting lamp, then the handle 6 is held by hand, and the button 9 is pulled by fingers, the clamping assembly 7 on the chuck 3 will release the locking state of all the second rods 5, so that the soft light box can be folded.

[0056] It should be noted that the above specific embodiments are only further descriptions of the present application combined with the embodiments, and do not constitute a limitation on the protection scope of the present application, if the present application is simply changed, all should belong to the protection scope of the present application, which realizes the purpose of the present application by the same means.
