Sliding grooves are provided on the inner side of the adjustment frame 10 near the four corners. The surfaces of the adjustment heads 21 are fixedly connected to the inner sides of the adjacent sliding grooves. Threaded rods 22 are provided through the inner sides of the adjustment heads 21 and are threadedly connected thereto. A mounting seat 23 is rotatably provided at one end of the threaded rods 22. The surfaces of the mounting seats 23 are slidably connected to the inner sides of the adjacent sliding grooves. A first bevel gear 24 is fixedly installed on the outer edge of the threaded rod 22 and located on the inner side of the adjustment head 21. A second bevel gear 25 is rotatably provided on the inner side of the adjustment head 21 and located on the top of the first bevel gear 24.

[0025] During use, the staff inserts the four radial limit members 33 into the inner angle interface of the fastener, manually rotates the adjustment block 26, and drives the threaded rod 22 to rotate through the meshing setting of the first bevel gear 24 and the second bevel gear 25. Through the threaded connection between the threaded rod 22 and the adjustment head 21, the mounting seat 23 is driven to slide outward on the inner side of the sliding groove, so that the outer wall of the radial limit member 33 is in contact with the inner angle interface, so that a strong locking effect is formed between the device and the fastener, and it is not easy to fall off from the inner angle interface when the device is rotated, and the operation is more convenient. This makes it easy for the staff to adjust according to the size of the inner angle interface of the fastener, greatly increasing the practicality of the device.

[0026] The fastening assembly 30 includes a fixing rod 31 rotatably disposed at the bottom of the adjusting head 21, a connecting block 32 is disposed at the lower end of the fixing rod 31, a radial stopper 33 is fixedly installed on one side of the connecting block 32, and a knob 34 for driving the fixing rod 31 to rotate is rotatably disposed at the top of the adjusting head 21;

[0032] A rotating handle 43 is rotatably provided on the inner side of the placement groove 42 near the top, and an anti-slip groove is provided on the outer edge of the rotating handle 43;

[0033] When the device is in use, the rotating handle 43 can be manually rotated to 90°, which makes it easier for the staff to rotate the fastener through the device. The storage function of the rotating handle 43 by the placement groove 42 reduces the space occupied by the device when not in use, making it easier to store.

[0034] The working principle of the adjustable fastening device for inner corner fasteners provided by the utility model is as follows:

[0035] Step 1: During use, the staff inserts the four radial stoppers 33 into the inner angle interface of the fastener, manually rotates the adjustment block 26, and drives the threaded rod 22 to rotate through the meshing setting of the first bevel gear 24 and the second bevel gear 25. Through the threaded connection relationship between the threaded rod 22 and the adjustment head 21, the mounting seat 23 is driven to slide outward on the inner side of the sliding groove, so that the outer wall of the radial stopper 33 is in contact with the inner angle interface, so that a strong locking effect is formed between the device and the fastener, and it is not easy to fall off from the inner angle interface when the device is rotated, and the operation is more convenient, which makes it easy for the staff to adjust according to the size of the inner angle interface of the fastener, greatly increasing the practicality of the device;

[0036] Step 2: When the radial limit member 33 is not in use or is to be replaced, the knob 34 is manually turned to drive the fixing rod 31 to rotate. Through the setting of the external thread 35 and the internal thread 36, the connecting block 32 drives the radial limit member 33 to move downward until the clamping block 37 is disengaged from the inner side of the clamping slot, and the radial limit member 33 is removed. This is not only more convenient for the staff to carry and store, but also saves space and cost, and is also convenient for the staff to replace the radial limit member 33, which greatly guarantees the service life of the device.

[0037] Compared with the related art, the adjustable fastening device for inner corner fasteners provided by the utility model has the following beneficial effects:

[0038] By cooperating with each other in the arrangement of the various parts of the device, the outer wall of the radial limit member 33 is in contact with the inner angle interface, so that a strong locking effect is formed between the device and the fastener. When the device is rotated, it is not easy to fall off from the inner angle interface, and the operation is more convenient. This makes it easy for the staff to adjust according to the size of the inner angle interface of the fastener, which greatly increases the practicality of the device. With the help of the fastening component 30 and the rotating component 40, the radial limit member 33 is disassembled. This is not only more convenient for the staff to carry and store, but also saves space and cost, and is also convenient for the staff to replace the radial limit member 33, which greatly guarantees the service life of the device.
