In the present invention, the strap head is used in conjunction with a strap with teeth, and the strap head and the strap are separately provided. During use, the length of the strap can be used according to demand to avoid waste. The outer end of the second elastic locking part 8 of the present invention is provided with a toggle part 10 and a yielding groove 11 is provided on the base 1. During use, the user can easily bend the second elastic locking part 8 to a certain angle, so that the strap can easily enter the second channel 9. The strap first enters from the second channel 9, and then enters the first channel 6 after bypassing the bound object. When the front end of the strap enters the first channel 6 and is flush with the end of the base 1, at this time, the first locking tooth 7 locks the teeth on the strap. The first locking tooth 7 is a one-way tooth, so the strap cannot retreat. At this time, the strap in the second channel 9 can be pulled to tighten it, and then the toggle part 10 is loosened. The second locking tooth 12 of the second elastic locking part 8 locks the teeth at the other end of the strap, and the strap is cut to complete the binding. The operation is simple and easy to use.
[0031] A releasable binding strap in the present invention comprises a binding strap 20 and a binding strap head 30, wherein teeth 40 are evenly distributed on at least one side of the binding strap 20, and the binding strap head 30 comprises a base 1, characterized in that: a first cavity 2 and a second cavity 3 are provided in the base 1, a partition 4 is provided between the first cavity 2 and the second cavity 3, a first elastic locking portion 5 is provided in the first cavity 2, a first passage 6 through which the binding strap can pass is provided between the first elastic locking portion 5 and the partition 4, a first locking tooth 7 that can be locked with teeth on the binding strap is provided on the side of the first elastic locking portion 5 facing the partition 4, a second elastic locking portion 8 is provided in the second cavity 3, a second passage 9 through which the binding strap can pass is provided between the second elastic locking portion 8 and the partition 4, a second locking tooth 12 that can be locked with teeth on the binding strap is provided on the side of the second elastic locking portion 8 facing the partition 4, a toggle portion 10 that is convenient for opening the second elastic locking portion 8 is provided on the outer end of the second elastic locking portion 8, and a clearance groove 11 is provided at the corresponding position of the base 1 and the toggle portion 10. In the present invention, the strap 20 and the strap head 30 are used together, and the second elastic locking part 8 can be opened to a certain angle by manually or by a device to toggle the toggle part 10, thereby facilitating the entry and loosening of the strap. The structure is simple and easy to use.
[0032] like Figure 6-9As shown, a strap binding device of the present invention includes a handle seat 50, a strap head mounting portion 51 is provided at the front end of the handle seat 50, a strap channel 52 is provided in the handle seat 50 for feeding a strap 20 into a strap head 30 of the strap head mounting portion 51, a front end of the strap channel 52 is connected to the strap head mounting portion 51, a rear end of the strap channel 52 passes through the rear end of the handle seat 50, a mounting slot hole 53 connected to the strap channel 52 is provided in the handle seat 50, and a mounting slot hole 53 is provided in the mounting slot hole 53. A transmission gear 54 is provided which can mesh with the teeth 40 on the strap 20, a connecting assembly groove 55 is provided between the strap head mounting portion 51 and the front end of the strap channel 52, a latching buckle 56 is provided in the lower part of the connecting assembly groove 55 which can open the second elastic locking portion 8 in the strap head 30 so as to facilitate the strap 20 to enter the second channel 9, a pressure block 57 which can drive the latching buckle 56 to move is provided in the handle seat 50, and a cutting mechanism 58 which can cut the strap 20 is provided in the upper part of the connecting assembly groove 55. The strap head in the present invention is installed in the strap head installation part 51, and the strap enters from the rear end of the strap channel 52, with one side of the strap teeth facing downward. When the strap enters the transmission gear 54, the teeth mesh with the transmission gear 54, and the strap continues to move forward, driving the transmission gear 54 to rotate. The transmission gear 54 drives the pressure block 57 to move, and the pressure block 57 moves downward to drive the tongue buckle 56 to move. The upper end of the tongue buckle 56 drives the second elastic locking part 8 to open, thereby facilitating the entry of the strap 20. After the strap enters the second channel 9, it extends out of the base 1, and then enters the first channel 6 after bypassing the tied object. When the front end of the strap enters the first channel 6, since the end of the first channel 6 is closed by the handle seat 50, the front end of the strap is flush with the end of the base 1. At this time, the first locking tooth 7 locks the teeth on the strap. The first locking tooth 7 is a one-way tooth, so the strap cannot retreat. At this time, the strap in the second channel 9 can be pulled, and the strap drives the gear 54 to rotate, causing 56 to reset and tighten it. The second locking teeth 12 of the second elastic locking part 8 lock the teeth at the other end of the strap, and the cutting mechanism 58 is pressed to cut the strap to complete the binding, which is simple to operate and easy to use. The present invention is provided with a convex point on the rotating shaft of the transmission gear 54, and the convex point is set at a position corresponding to the rear end of the pressure block 57. During the rotation process of the transmission gear 54, when the convex point contacts the pressure block 57, the pressure block 57 is forced to move downward. When the pressure block 57 moves downward to the lowest end, the convex point passes over the extreme end of the pressure block 57. At this time, the transmission gear 54 can continue to rotate, thereby ensuring that the strap can move forward smoothly.
[0033] The cutter mechanism 58 described in the present invention includes a handle bar 581 hinged on the front end of the handle seat 50, a first cutter 582 is hinged at the position corresponding to the handle bar 581 and the connection assembly groove 55, and a pressing spring mechanism 583 is provided between the handle bar 581 and the handle seat 50. In the present invention, the connection assembly groove 55 and the strap channel 52 are arranged perpendicular to each other, and the first cutter 582 moves downward under the action of the handle bar 581. The first cutter 582 can cut the strap and simultaneously make the tongue buckle 56 separate from the toggle portion 10 of the strap head, effectively ensuring that the strap will not retreat.
[0034] The pressing spring mechanism 583 of the present invention comprises a lower spring slot 5831 disposed on the handle base 50, an upper spring slot 5832 is disposed at a position corresponding to the lower spring slot 5831 of the handle rod 581, and a spring 5833 is disposed in the lower spring slot 5831 and the upper spring slot 5832. The pressing spring mechanism 583 of the present invention is disposed at the front of the handle base 50, and can effectively reset the handle rod 581.
[0035] The tongue buckle 56 described in the present invention includes a body 561, a crimping portion 562 is provided at the lower end of the body 561, a clearance groove 59 connected to the connection assembly groove 55 is provided at the lower part of the handle seat 50, the crimping portion 562 is arranged in the clearance groove 59, one end of the pressing block 57 is crimped on the crimping portion 562, a hooking portion 563 capable of toggling the toggle portion 10 is provided at the upper end of the body 561, and the other end of the pressing block 57 is connected to the transmission gear 54.
