Two arc plates are disposed on the connection mount. The tripod device has a positioning seat, three rods, and a corrugation tube. The corrugation tube is disposed on the positioning seat. The positioning seat has three periphery holes, three lower notches matching the periphery holes, and three inner blocks. Each of the inner blocks has an upper notch. The rod is inserted in the respective periphery hole of the positioning seat. A corrugation tube is disposed on the positioning seat. The corrugation tube receives the lower pipe. The first adjustment device has a first sleeve, a first main body disposed on the first sleeve, a first lateral pipe connected to the first main body, a first packing block, a first washer, and a first button. The first lateral pipe has an inner recess. The first main body has a first hollow collar and a first square block. The first hollow collar has a first inner protrusion and a first through hole. The first square block has a first hexagonal hole. A first screw rod passes through the first hexagonal hole of the first square block, the first packing block, the first washer, and the first button. The corrugation tube is inserted in the first sleeve. The lower pipe is inserted in the first through hole of the first hollow collar. The bracket device has an insertion tube inserted in the first lateral pipe, a connection seat connected to the insertion tube, and two arm plates disposed on the connection seat. A hollow interior is formed in the first lateral pipe to communicate with the inner recess of the first lateral pipe. The insertion tube has a protruded block inserted in the hollow interior of the first lateral pipe via the inner recess of the first lateral pipe. An elastic cushion is disposed on the connection seat. The second adjustment device has a second sleeve, a second main body disposed on the second sleeve, a second packing block, a second washer, and a second button. The second main body has a second hollow collar and a second square block. The second hollow collar has a second inner protrusion and a second through hole. The second square block has a second hexagonal hole. A second screw rod passes through the second hexagonal hole of the second square block, the second packing block, the second washer, and the second button. The lower pipe is inserted in the second sleeve. The upper pipe is inserted in the second through hole of the second hollow collar.
