Specifically, the rotating hole 1121 is formed in the rotating groove 1120, the fixing rod rotating pins 1141 are arranged on two sides of one end, located in the rotating groove 1120, of the fixing rod 114, the fixing rod rotating pins 1141 are located in the rotating hole 1121 to rotate, and the fixing rod 114 is conveniently separated from the fixing groove 1130 through rotation between the fixing rod 114 and the rotating block 112, so that the effect of separating the three arc-shaped fixing pieces 110 is achieved.

In addition, the slider 115 that arc stationary blade 110 was equipped with through the internal surface is connected with laminating piece 140, and laminating piece 140 is the arc structure, is convenient for with the laminating of arbor surface, and the foam-rubber cushion has been laid to laminating piece 140 internal surface, is convenient for protect the surface of arbor, avoids the arbor impaired.

In addition, laminating piece 140's surface is equipped with connector 141, connector 141 is equipped with a plurality of, slider 115 is inside to have seted up spout 1150, connector 141 slides inside spout 1150, the one end that connector 141 is located spout 1150 inside is equipped with spring 1411, spring 1411 one end welds with spout 1150, through connector 141 and slider 115's slip, be convenient for change laminating piece 140's use radius, be favorable to using different specification trees, through spring 1411's elastic force effect, be convenient for when laminating piece 140 and arbor contact, play certain extrusion force, thereby further stabilize the arbor.

Further, one end of the connector 141 close to the slider 115 is provided with a connector limiting ring 1412, so that the connector 141 is prevented from easily sliding out of the sliding groove 1150, the surface of the attaching piece 140 is provided with an attaching piece opening 1400, and the attaching piece opening 1400 is in a square opening shape, thereby facilitating ventilation of the arbor.

Specifically, slide bar 111 one side surface is equipped with spacing slide 1111, and the width of spacing slide 1111 is greater than slide bar 111's width, and connecting rod sliding chamber 1210 is inside to have seted up spacing groove 1214, and spacing slide 1111 is located the inside slip of spacing groove 1214, is convenient for when slide bar 111 slides, play spacing effect.

In addition, the both sides surface of bracing piece 120 all is equipped with bottom surface fixed plate 122, bottom surface fixed plate 122 one side is equipped with connecting plate 1221, connecting plate 1221 and bracing piece 120 fixed connection, fixed plate through-hole 1222 has all been seted up at the both ends of bottom surface fixed plate 122, fixed plate through-hole 1222 is inside to be pegged graft there is inserted bar 1223, with inserted bar 1223 run through fixed plate through-hole 1222 insert ground, the bottom surface fixed plate 122 of being convenient for is connected with ground to play the effect of firm bracing piece 120.

In addition, the top end of the insertion rod 1223 is provided with an insertion rod limiting block 1224, the radius of the insertion rod limiting block 1224 is larger than the radius of the fixing plate through hole 1222, when the insertion rod 1223 is inserted into the ground, the insertion rod limiting block 1224 is in contact with the upper surface of the bottom fixing plate 122, and the stability of connection between the insertion rod 1223 and the fixing plate through hole 1222 is further improved.

Furthermore, one end of the connecting rod sliding cavity 1210 is provided with a limit plate 1215, the inner surface of the limit plate 1215 is attached to the surface of the sliding rod 111, so that the side surface of the sliding rod 111 is limited, and the sliding rod 111 is prevented from easily separating from the connecting rod sliding cavity 1210, and the normal use is prevented from being influenced.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention.
