Wherein the inner end of the extension bar 23 is pivotally connected to the top frame unit 2 to allow the extension bar 23 to be flipped up relative to the top frame unit 2 when the shade product holder 100 is tipped over. The inner end of the first ejector rod 21 is rotatably connected to the top cap 3; the joint 25 is disposed at the outer end of the first ejector rod 21, and the two are fixedly connected or integrally disposed. The inner end of the second ejector rod 22 is rotatably connected to the first slider 4, and the outer end of the second ejector rod 22 is rotatably connected to the joint 25. The inner end of the extension rod 23 is rotatably connected to the joint 25, and the outer end is extended outwardly and may be provided with a connection piece 26, and the connection piece 26 is provided with a connection hole or a connection groove to facilitate connection with the cloth cover 200, etc., providing a large shielding area. The upper end of the diagonal brace 24 is rotatably connected to the first jack 21 or the second jack 22, and the lower end of the diagonal brace 24 is rotatably connected to the second slider 5. In the embodiment, the first ejector rod 21 of each top frame unit 2 is pivotally connected to the top cap 3, the second ejector rod 22 of each top frame unit 2 is pivotally connected to the first slider 4, and the diagonal brace 24 of each top frame unit 2 is pivotally connected to the second slider 5. As shown in fig. 12, the extension rod 23 is connected to the joint 25 through a first pivot a1, the second jack 22 is connected to the joint 25 through a second pivot a2, and the first jack 21, the second jack 22, the center support rod 1 and the first slider 4 thereon of each jack unit 2 constitute a crank slider mechanism; the first carrier rod 21, the diagonal brace 24, the central support rod 1 and the second slide 5 thereon of each top frame unit 2 constitute a crank slide mechanism.

Further, in the present embodiment, each top frame unit 2 includes two second ejector pins 22, and the two second ejector pins 22 are connected between the same joint 25 and the first slider 4 in parallel to enhance the strength of the top frame unit 2. A gap is arranged between the two second ejector rods 22, and the diagonal brace 24 passes through the gap between the two second ejector rods 22 and is respectively connected with the first ejector rod 21 and the second sliding block 5. The length of the diagonal brace 24 is smaller than that of the first ejector rod 21 and the second ejector rod 22, and the distance between the joint of the diagonal brace 24 and the first ejector rod 21 and the outer end of the first ejector rod 21 is smaller than one half of the length of the first ejector rod 21, and the sum of the distance and the length of the diagonal brace 24 is smaller than or equal to the length of the second ejector rod 22. In addition, the difference in length between the first jack 21 and the second jack 22 is less than one tenth of the length of the second jack 22; preferably, the length of the first ejector pin 21 is smaller than the length of the second ejector pin 22. When the shielding product holder 100 is in the folded state, the upper end portion of the first ejector rod 21 and the upper end portion of the second ejector rod 22 are close together (the two are substantially flat, or the difference in height is much smaller than 1/10 of the length of the first ejector rod 21), and the lower end portion of the first ejector rod 21 is higher than the upper end portion of the second ejector rod 22. When the shielding product holder 100 is in the folded state, the diagonal brace 24 is accommodated between the two second ejector rods 22 in each top frame unit 2, so as to fully utilize the internal space and avoid the overlarge overall volume after folding.

In other embodiments, each roof rack unit 2 includes two first roof bars 21, and the number of second roof bars 22 is one. The two first push rods 21 are connected in parallel between the same joint 25 and the top cap 3 to enhance the strength of the top frame unit 2. The diagonal strut 24 is rotatably connected to at least one of the first rams 21.

Further, the joint 25 not only rotationally connects the extension rod 23 with the first ejector rod 21 and the second ejector rod 22, but also plays a role in limiting the rotation of the extension rod 23; in particular, the joint 25 is configured to allow only the extension bar 23 to be flipped up relative to the top frame unit 2 when the shade product holder is tipped over. As shown in fig. 9 and 19, the joint 25 has a receiving groove 254, and the outer end portion of the extension rod 23 is received in the receiving groove 254 when the shield product holder 100 is in the unfolded state. The upper portion of the receiving groove 254 is opened to allow the extension rod 23 to be rotated out of the receiving groove 254 to be drawn toward each other with the first push rod 21. The central line of the extension rod 23 and the central line of the first push rod 21 coincide or are parallel to each other in the unfolded state of the shielding product, and the receiving groove 254 also extends along the central line of the extension rod 23. The upper portion and the outer end of the accommodating groove 254 are open, the lower portion of the accommodating groove 254 is closed, when the shielding product holder 100 is in the unfolded state, the extension rod 23 leans against the lower portion of the accommodating groove 254, the lower portion of the accommodating groove 254 has a rotation limiting effect on the extension rod 23, the extension rod 23 can be prevented from turning downwards, and the extension rod 23 can be turned upwards to be close to the first ejector rod 21. When the shade product holder 100 is in the deployed state, the first pivot a1 is above the centerline of the extension rod 23 and the second pivot a2 is below the centerline of the extension rod 23.

The joint 25 has an impact buffer 253 that lands when the shield product holder 100 is turned upside down, and the entire holder is supported by the impact buffer 253 of the joint 25 that lands when the shield product holder 100 is turned upside down or is placed obliquely on the ground; at this time, the impact buffer 253 protrudes outwards relative to the first pivot a1, the second pivot a2, the inner end of the extension rod 23 and the outer end of the second ejector rod 22, so as to effectively avoid the end of the rod member (especially the outer end of the second ejector rod 22) from directly contacting, thereby reducing the risk of bending deformation or breakage of the rod member.

The joint 25 includes a body 251 and a metal reinforcing sheet 252 fixedly connected to the body 251, wherein the body 251 is a plastic member, which can be manufactured by an integral injection molding process.

Further, the metal reinforcing sheet 252 extends from the first pivot a1 to the second pivot a2, and two ends of the metal reinforcing sheet 252 are respectively provided with a pivot hole for the first pivot a1 and the second pivot a2 to pass through. The first pivot a1 is inserted into the upper end portions of the body 251 and the metal reinforcing sheet 252, the second pivot a2 is inserted into the lower end portions of the body 251 and the metal reinforcing sheet 252, and the metal reinforcing sheet 252 is connected to the body 251 by the first pivot a1 and the second pivot a2, so as to effectively strengthen the connection strength among the first push rod 21, the second push rod 22 and the extension rod 23. In this embodiment, each top frame unit 2 includes two second push rods 22 and is connected to the joints 25 in parallel, so that the number of the metal reinforcing sheets 252 is also two, and the metal reinforcing sheets are respectively disposed on two opposite sides of the body 251. The body 251 of the joint 25 further has a plug 251a, and the plug 251a is inserted into the outer end portion of the first jack 21 and fixed to the first jack 21 by a fastener such as a screw or a rivet.

In other embodiments, as shown in fig. 26, the metal reinforcing sheet 252 has three ends, which are generally L-shaped. Two ends of the metal reinforcing sheet 252 are provided with pivot holes, and the first pivot a1 and the second pivot a2 pass through the pivot holes respectively; the third end portion is provided with a connecting hole through which a fastener a3 such as a screw or a rivet passes and fixedly connects the joint 25 (specifically, the third end portion of the plug 251a and the metal reinforcing piece 252) with the outer end portion of the first jack 21. The strength of the joint of the first ejector rod 21, the second ejector rod 22 and the extension rod 23 is effectively enhanced.
