[0054] Compared with the prior art of manually forcibly unfolding the support leg 2, the practical locking assembly 3 releases the limit on all support legs 2 after triggering, so that the support leg 2 is in the unfolded / expandable state; it is more convenient and labor-saving than manually forcibly opening. And the limit is released by the top block pressing, which is a clever structure design.

[0055] In this embodiment, the number of support legs of the support leg 2 frame is 3, but it should not be understood as being limited to this, and it can also be 4, 5 or other numbers.

[0056] In this embodiment, the stimulation mode of the trigger button 31 includes pressing or rotating or hitting; but it is not limited to this.

[0057] Referring to Figures 5-8 , the clamping structure 32 comprises a first protrusion 321, and the support leg 2 is provided with a second protrusion 21; and the second protrusion 21 is connected with the support leg 2 through a second elastic member 22; when the clamping structure 32 fits with the support leg 2, the first protrusion 321 and the second protrusion 21 abut against each other; the rotation of the support leg 2 relative to the main rod 1 is limited; when the top block 33 presses the support leg 2, the top block 33 presses the second protrusion 21, so that the second protrusion 21 shrinks inwardly of the support leg 2, and the abutment of the second protrusion 21 and the first protrusion 321 is released; and the support leg 2 is in the unfolded / expandable state.

[0058] In this embodiment, the support leg 2 is provided with a space for accommodating the second protrusion 21 and the second elastic member 22, and the second protrusion 21 can be completely accommodated in the support leg 2 and not exposed.

[0060] The second elastic member 22 can be a spring or a spring sheet.

[0061] In the specific scheme, the lever 37 with the fulcrum is in the shape of a "V", the trigger button 31 and the top block 33 are arranged at two ends of the "V" respectively, and the middle of the "V" is the fulcrum; in the rising and falling process of the trigger button 31, the end of the lever 37 connected with the top block 33 is arc-displaced, in order to make the top block 33 only linearly displace, the top block 33 is rotatably connected with the lever 37; and the top block 33 is limited in a linear channel, so that the moving track of the top block 33 is a straight line; the top block 33 can more directly and effectively press the second protrusion 21.

[0062] In the embodiment, one end of the lever 37 is provided with a rotating shaft, the top block is provided with two opposite hole positions, the rotating shaft is inserted into the hole positions, and a rotatable structure of the top block 33 relative to the lever 37 is formed.

[0063] In the embodiment, the locking structure 3 further includes a supporting plate 35, one end of the supporting plate 35 is connected with the main rod 1, the other end is provided with a connecting column 351, the first elastic member 38 is sleeved on the connecting column 351, the other end of the first elastic member 38 abuts against the trigger button 31; and the fulcrum of the lever 37 falls on the supporting plate 35; the supporting plate 35 provides a supporting force for the trigger button 31.

[0064] In the example, one end of the supporting plate 35 connected with the main rod 1 can be directly connected or indirectly connected through other structures; the connecting column 351 can be multiple, and the first elastic member 38 is correspondingly provided with multiple first elastic members 38; stronger restoring force is provided.

[0065] In the embodiment, the locking structure 3 further includes a fixing seat 36, the supporting plate 35 is connected with the main rod 1 through the fixing seat 36; and the fixing seat 36 is provided with a connecting groove of the reinforcing rib 4, and the supporting plate 35 is used for pressing and fitting the connecting groove of the reinforcing rib 4.

[0066] Specifically, the trigger button 31 is provided with a groove, and the other end of the first elastic member 38 extends into the groove and abuts against the bottom or sidewall of the groove.

[0067] Referring to Figure 3 , the clamping structure 32 further comprises a limiting cover 322, and the first protrusion 321 is arranged on the limiting cover 322. The limiting cover 322 is used to enclose an activity space with the support plate 35, one end of the trigger button 31 extends into the activity space, and the trigger button 31 moves in the activity space after being stimulated. The end of the trigger button 31, which is sleeved with the first elastic member 38, is provided with an extension 311, which surrounds the axial direction of the trigger button 31 and is used to abut against the limiting cover 322 or the support plate 35 to limit the displacement of the trigger button 31 in the activity space.

[0068] In the embodiment, the limiting cover 322 is provided with an opening for the top block to extend out of or retract into the activity space. When the top block extends out of the activity space, it presses the second protrusion 21, so that the second protrusion 21 retracts into the support leg 2 and no longer abuts against the first protrusion 321. When the top block 33 retracts into the activity space, the second protrusion 21 abuts against the first protrusion 321 to limit the rotation of the support leg 2 relative to the main rod 1.

[0069] Referring to Figure 9 , in order to more conveniently expand the support leg 2, the end of the trigger button 31 away from the top block is provided with a pressing block 34. When the trigger button 31 is pressed, the clamping structure 32 releases the restriction on the support leg 2, and at the same time, the pressing block 4 moves with the trigger button 31, presses the support leg 2, and makes the support leg 2 move in the direction of expansion. The pressing block 4 is away from the original position. At this time, the trigger button 31 is released in time, the second protrusion 21 retracts from the support leg 2, and cannot abut against the first protrusion 321 again. The support leg 2 is in an expandable state. Then, the support leg 2 is manually rotated to expand the support leg 2, without forcibly separating the support leg 2, and more labor-saving.

[0070] In the embodiment, the pressing block 34 protrudes from the side surface of the trigger button 31 and has a sloping surface structure. The sloping surface is used to guide the support leg 2 to move along the sloping surface when the pressing block 34 moves. When the pressing block 34 contacts the support leg 2 and presses the support leg 2 away from the original position, the contact point between the support leg 2 and the pressing block 311 is the pressing point 23. When the trigger button 31 is not pressed, the pressing block 34 does not contact the pressing point 23. After the trigger button 31 is pressed, the pressing point 23 moves relative to the sloping surface of the pressing block 34, the support leg 2 gradually moves away from the original locked position, and the pressing point 23 cannot press the support leg 2.

[0071] Due to the extrusion of the extrusion block 34 to the support leg 2; at this time, even if the trigger button 31 is released, the second protrusion 21 is extended from the support leg 2, the support leg 2 will not be in contact with the clamping structure 32 again, and the support leg 2 is in an expandable state; it is convenient for subsequent expansion.

[0072] In the embodiment, the main rod 1 is provided with a connecting seat 5, one end of the support leg 2 is rotatably connected with the connecting seat 5, and the other end is a free end. When the free end of the support leg 2 is matched with the locking assembly 3, the support leg 2 is in a folded state. When the free end of the support leg 2 is not matched with the locking assembly 3, the support leg 2 is in an expanded or expandable state. The connecting seat 5 can be sleeved on the main rod 1 and slide relative to the main rod 1.

[0073] In the embodiment, the reinforcing rib 4 is rotatably connected with one end of the support leg 2 and the other end of the support leg 2 is rotatably connected with the fixed seat 36. The reinforcing rib can greatly improve the stability of the support leg 2.
