[0030] The locking support 10 comprises a horizontal plate 101, a second column 102 and a circular hole 103, the circular hole 103 is arranged in the horizontal plate 101, the bottom of the horizontal plate 101 is attached to the upper surface of the upper hoop 1, the inner wall of the circular hole 103 is attached to the surface of the first bolt 11, the upper surface of the second column 102 is fixedly connected to the bottom of the horizontal plate 101, and the side surface of the first column 81, the inner wall of the groove 4 and the inner wall of the special-shaped hole 6 are attached to the surface of the second column 102.

[0031] It should be noted that the cooperation of the first U-shaped plate 83 and the cylinder 7 enables the first column 81 to move left and right only in the special-shaped hole 6, when the first column 81 is inserted into the groove 4, the inclined surface on the second trapezoidal block 82 first contacts the inclined surface on the first trapezoidal block 5, then the inclined surface enables the distance between the left and right first columns 81 to automatically increase during the downward movement, when the second trapezoidal block 82 moves below the first trapezoidal block 5, the pulling force of the spring 9 on the first column 81 enables the distance between the left and right first columns 81 to return to the original size, when the user fixes the second column 102 in the groove 4 and the special-shaped hole 6 through the cooperation of the first bolt 11, the first threaded groove 12, the circular hole 103 and the horizontal plate 101, the second trapezoidal block 82 on the fixed support 8 and the first trapezoidal block 5 in the groove 4 can be fixed together through the second column 102, and the upper hoop 1 and the lower hoop 2 can be fixed on the transmission main shaft through the cooperation of the first trapezoidal block 5 and the second trapezoidal block 82, at the same time, when the second column 102 is pulled out of the groove 4 and the special-shaped hole 6, since the direct contact surface between the first trapezoidal block 5 and the second trapezoidal block 82 is an inclined surface, and the first column 81 can move left and right freely in the special-shaped hole 6, the first column 81 can be directly pulled out of the groove 4, and the upper hoop 1 and the lower hoop 2 can be directly separated from the transmission main shaft.

[0032] As Figures 1 to 10As shown, the inner wall of the upper hoop 1 and the inner wall of the lower hoop 2 are provided with arc-shaped partitions 13, the surface of the arc-shaped partition 13 is fixedly connected with a second U-shaped plate 14, the front and rear sides of the upper hoop 1 and the front and rear sides of the lower hoop 2 are attached to the surface of the second U-shaped plate 14, the front and rear sides of the upper hoop 1 and the front and rear sides of the lower hoop 2 are provided with second threaded grooves 15, the inner wall of the second threaded groove 15 is threadedly connected with a second bolt 16, and the surface of the second bolt 16 is attached to the inner wall of the second U-shaped plate 14.

[0033] The left and right sides of the second U-shaped plate 14 and the surface of the arc-shaped partition 13 are fixedly connected with reinforcing blocks 17, so that the second U-shaped plate 14 and the arc-shaped partition 13 are fixed more firmly.

[0034] It should be noted that the cooperation of the second U-shaped plate 14, the second threaded groove 15 and the second bolt 16 can fix the arc-shaped partition 13 on the upper hoop 1 and the lower hoop 2, and separate the upper hoop 1 and the lower hoop 2 from the transmission main shaft through the arc-shaped partition 13, so that only the arc-shaped partition 13 is worn after the transmission connecting piece is used for a period of time, and the transmission connecting piece can continue to be used by replacing the worn arc-shaped partition 13, thereby reducing the use cost of the transmission connecting piece.

[0035] The use principle of the utility model is as follows: first, the first bolt 11 is screwed out of the first threaded groove 12, then the second column 102 is pulled out of the groove 4 and the special-shaped hole 6, the first column 81 on the fixed support 8 is moved out of the groove 4 by moving the upper hoop 1 upwards, the arc-shaped partition 13 on the lower hoop 2 is contacted with the transmission main shaft, and the first column 81 on the fixed support 8 is inserted into the groove 4, at this time, after the first column 81 is inserted into the groove 4, the inclined surface on the second trapezoidal block 82 first contacts the inclined surface on the first trapezoidal block 5, then the distance between the left and right first columns 81 is automatically increased in the downward movement process through the inclined surface, and when the second trapezoidal block 82 moves below the first trapezoidal block 5, the distance between the left and right first columns 81 returns to the initial size through the pulling force of the spring 9 on the first column 81.
