DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element at the same time. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0020] Figure 1 Schematic diagram of the structure of a tenon hoop according to an embodiment of the present invention. Figure 1-3 As shown:

[0021] The utility model provides a tenon hoop, comprising a first tenon hoop blade 1 and a second tenon hoop blade 2, one end of which is rotatably arranged on a pin shaft 3, a semi-cylindrical groove is respectively arranged on the opposite sides of the first tenon hoop blade 1 and the second tenon hoop blade 2, a first through hole 12 is arranged at the other end of the first tenon hoop blade 1, and a second through hole 21 is arranged on the other end of the second tenon hoop blade 2 at a position corresponding to the first through hole 12.

[0022] Specifically, two half-cylinder tenon hoop leaves are hinged together with the pin axis 3 as the axis. When the first tenon hoop leaf and the second tenon hoop leaf are rotated and closed around the pin axis, a complete cylinder is formed. During the closing process, the cylinder is placed on the struck end of the double-headed tenon and fixed through the through holes on the two leaves. Then, it is struck to make the other end of the double-headed tenon enter the mortise and tenon hole. Under the protection of the cylinder structure of the tenon hoop, the structure of the end of the double-headed tenon is ensured to be intact, and the two tenons are prevented from being damaged when they enter the reserved holes of the solid wood workpiece under excessive interference force.

[0023] As an optional implementation, the pin shaft 3 is an offset pin.

[0024] As an optional embodiment, the semi-cylindrical groove is a semi-cylindrical or semi-rectangular cylinder. Figure 1 and Figure 3 Shown are embodiments in which the groove is semi-cylindrical and semi-rectangular, respectively, which are used for the assembly of double-ended cylindrical tenons and double-ended rectangular tenons.

[0025] As an optional embodiment, the end of the first tenon fixing hoop blade 1 connected to the pin shaft 3 is provided with an upper ear 14 and a lower ear 15, and the end of the second tenon fixing hoop blade 2 connected to the pin shaft 3 is provided with a middle ear 23, and the upper ear 14, the middle ear 23 and the lower ear 15 are rotatably sleeved on the pin shaft 3 in sequence. By providing concentric holes on the upper ear 14, the middle ear 23 and the lower ear 15, and rotatably sleeved on the pin shaft 3, the tenon fixing hoop can be conveniently sleeved on the end of the double-headed tenon and is easy to remove.

[0026] As an optional embodiment, the first tenon fixing hoop blade 1 and the second tenon fixing hoop blade 2 are provided with bosses on the sides corresponding to the bottom of the grooves. Figure 1-3As shown, bosses are respectively arranged on the first tenon hoop blade 1 and the second tenon hoop blade 2 to provide a striking structure. At the same time, the tenon hoop blades are made of a strong and striking-resistant material.

[0027] As an optional embodiment, a nut 4 is provided at the rear side of the second through hole 21. When the mortise and tenon hoop is sleeved on the end of the double-headed tenon, the two blades of the mortise and tenon hoop are fixed by bolts 5 and nuts 4, and the double-headed tenon wedge assembly can be inserted into the reserved hole of the main part, and the top of the mortise and tenon hoop boss is hit to complete the mortise and tenon wedge assembly.
