In this embodiment, it is preferable that the distance from the top of the pressing block 25 to the top of the third arc-shaped block 13 is 0.5 times the distance from the end of the support rod 243 located inside the sleeve 241 to the bottom of the inner wall of the sleeve 241. The operating personnel pushes down according to the briquetting 25, makes according to briquetting 25 and first through-hole 4 complete separation, and operating personnel moves according to briquetting 25 this moment, and according to briquetting 25 and drive the motion of reset assembly 24, reset assembly 24 drives sliding block 23 and removes, finally reaches the purpose that makes the arc pole motion.

The implementation principle of the above embodiment is as follows: when an operator fixes trees, firstly, fixing rings 1 with different specifications and sizes are selected according to the thickness of the trees to be fixed, so that the fixing rings 1 can be smoothly unfolded around the trees, and the trees are wrapped in the fixing rings 1.

An operator firstly places the fixing ring 1 which is not unfolded close to the tree, and then the operator sequentially unfolds the third arc-shaped block 13 and the second arc-shaped block 12 to enable the first arc-shaped block 11, the second arc-shaped block 12 and the third arc-shaped block 13 to be connected end to end. At this time, the tree is in the annular space of the fixing ring 1.

Further, the operator rotates the support frame 8 into the threaded hole 73 of the rotating plate 72 at the bottom of the fixing ring 1, so that one end of the support frame 8 contacts with the ground, and the fixing ring 1 is supported on the outer surface of the tree. In addition, the operator can rotate the support frame 8 according to the leveling condition of the bottom surface around the tree, the support frame 8 drives the rotating plate 72 to rotate around the fixing rod 71, and when the fixing ring 1 is in a horizontal state, the support frame 8 stops being adjusted.

Then, the operator presses the pressing block 25 downward, the pressing block 25 drives the supporting rod 243 to move downward inside the casing 241, and the supporting rod 243 drives the spring 242 to be in a compressed state. According to a briquetting 25 and the separation of first through-hole 4, press briquetting 25 to get into the third recess 6 when inside completely, operating personnel keeps pressing briquetting 25 to be located under the unchangeable condition of current position, and operating personnel removes and presses briquetting 25, presses briquetting 25 to drive the motion of subassembly 24 that resets, and the subassembly 24 that resets drives sliding block 23 motion, and sliding block 23 drives the motion of arc pole 22. When the major part of the curved rod 22 enters the curved tube 21 inside the second curved block 12, the operator no longer applies pressure to the pressing block 25.

At this time, due to the elastic restoring force of the spring 242 in the restoring assembly 24, the spring 242 is restored to the initial position, the spring 242 drives the supporting rod 243 to return to the initial position, the supporting rod 243 drives the pressing block 25 to return to the initial position, that is, a part of the pressing block 25 passes through the first through hole 4, the tooth grooves 251 on the outer side of the pressing block 25 are in contact with the limiting teeth 41 on both sides of the inner wall of the first through hole 4, and the position of the pressing block 25 is fixed. In the absence of external forces, the first through hole 4 limits the movement of the pressing block 25, i.e. the arc rod 22 is mostly located inside the arc tube 21, so that the second arc block 12 is tightly connected with the third arc block 13.

Then, the operator rotates the rotating handle 53, the rotating handle 53 drives the screw 52 to rotate inside the threaded pipe 51, the screw 52 moves along the linear direction of the central axis of the threaded pipe 51 while the screw 52 rotates, and the screw 52 drives the pressing block 54 to move. Since the pressing block 54 is rotatably connected with the screw rod 52, and the side of the pressing block 54 close to the screw rod 52 is fixedly connected with the sliding rod 61, and the sliding rod 61 makes a linear motion inside the second groove 3, when the screw rod 52 rotates, the pressing block 54 itself cannot rotate. An operator rotates the screw rod 52, so that the screw rod 52 drives the pressing block 54 to move towards the direction of the tree, when the pressing block 54 is in contact with the tree, the rubber block 55 on the side, away from the screw rod 52, of the pressing block 54 is in contact with the tree, and the pressing block 54 is prevented from being in direct contact with the tree to damage the surface of the tree.

When an operator needs to disassemble the tree fixing device, the operator firstly turns over the rotating handle 53, the rotating handle 53 drives the screw rod 52 to rotate inside the threaded pipe 51, and since the screw rod 52 is rotatably connected with the pressing block 54 and the pressing block 54 is fixedly connected with the sliding rod 61, when the screw rod 52 rotates, the screw rod 52 moves along the direction of the straight line of the central axis of the threaded pipe 51, and the screw rod 52 drives the pressing block 54 to move towards the direction departing from the tree.

When the holding-down blocks 54 return to the initial position, the operator separates the two support frames 8 supporting the second arc-shaped block 12 and the third arc-shaped block 13 from the fixed ring 1.

Further, while the operator holds the fixing ring 1, the operator presses the pressing block 25, the pressing block 25 drives the spring 242 in the reset assembly 24 to be in a compressed state, the support rod 243 in the reset assembly 24 moves inside the sleeve 241, and when the pressing block 25 is separated from the first through hole 4. The operator keeps pressing the pressing block 25 and the posture is unchanged, moves the pressing block 25 at the same time, the pressing block 25 drives the resetting component 24 to move, the resetting component 24 drives the sliding block 23 to move along the linear direction of the first sliding groove 31, and the sliding block 23 drives the arc-shaped rod 22 to move.

When the arc rod 22 is separated from the arc tube 21, the operator continues to slide one end of the pressing block 25, then releases the pressing block 25, the spring 242 in the reset assembly 24 drives the support rod 243 to move upwards, the support rod 243 drives the pressing block 25 to move upwards, so that the pressing block 25 passes through the first through hole 4 at 3, and at the moment, the spring 242 returns to the natural state.

An operator unscrews the support frame 8 on the first arc-shaped block 11, and the operator enables the second arc-shaped block 12 and the third arc-shaped block 13 to respectively overturn along the edges of the two ends of the first arc-shaped block 11, so that the second arc-shaped block 12 and the third arc-shaped block coincide with the first arc-shaped block 11.

Finally, the operator collects the three support frames 8 and places them together with the fixed ring 1 in the folded state. The portable multifunctional electric water heater is convenient for operators to carry, and the occupied space of the device is reduced.

In particular, when the three arc-shaped blocks at the fixing ring 1 are in a superposed state, the arc-shaped rod 22 is completely inside the third arc-shaped block 13.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
