[0030] When the pipe needs to be carried for a long distance, the carrying personnel can avoid holding the upper handle and the lower handle for a long time, which leads to the increase of the labor intensity of the carrying personnel, the locking mechanism 5 can lock the upper handle 6 and the lower handle 7, so that the upper handle 6 and the lower handle 7 are kept in the state of tightening at all times, greatly reducing the labor intensity of the carrying personnel.

[0031] The scissors mechanism 3 includes inner scissors arm 10 and outer scissors arm 11, the middle part of the inner scissors arm 10 and the outer scissors arm 11 is connected through the pin shaft, the pin shaft is sleeved with the torsional spring, the two ends of the torsional spring are connected with the inner scissors arm 10 and the outer scissors arm 11 respectively, the two ends of the inner scissors arm 10 are connected with the upper handle 6 and the lower clamp rod 9 respectively, the two ends of the outer scissors arm 11 are connected with the lower handle 7 and the upper clamp rod 8 respectively.

[0032] Due to the two ends of the torsional spring are connected with the inner scissors arm 10 and the outer scissors arm 11 respectively, when no external force is applied to the device, due to the action of the torsional spring, the upper clamp rod 8 and the lower clamp rod 9 are separated from each other, which is convenient for the carrying personnel to hold the device and quickly clamp and carry the pipe, avoiding the carrying personnel to manually separate the upper handle and the lower handle, so that the upper clamp rod 8 and the lower clamp rod 9 are separated from each other, greatly improving the convenience of the device in use.

[0033] The locking mechanism 5 comprises a rotating rack 12, one end of which is connected to the lower handle 7 through a rotating shaft, and the end of the upper handle 6 away from the scissor mechanism 3 is provided with a tooth 13 which is engaged with the rotating rack 12. The upper handle 6 is provided with a rotating limiting piece 14 on one side, which is arranged at the end of the upper handle 6 close to the tooth 13.

[0034] The rotating rack 12 and the tooth 13 are both made of metal. When the pipe needs to be transported to a certain distance, the pipe is clamped tightly, the rotating rack 12 is turned upward, the rotating rack 12 and the tooth 13 are engaged with each other, and then the rotating limiting piece 14 is rotated to the side away from the tooth 13 of the rotating rack 12, so as to ensure that the rotating rack 12 and the tooth 13 are tightly engaged and avoid slipping, thereby realizing the fixing effect between the upper handle 6 and the lower handle 7 and reducing the labor intensity of the transporter when transporting the pipe.

[0035] The upper handle 6 and the lower handle 7 are both coated with a rubber coating, and the length of the clamping rod 2 is half of the length of the handle 1.

[0036] By lengthening the length of the handle 1, a larger gripping range is provided, the stability and control force of holding the object are increased, the hand pressure is reduced, the hand fatigue is reduced, and the use of the tool or instrument for a long time is more comfortable.

[0041] When the pipe material to be carried is more, the carrying personnel at both ends of the pipe material need to confirm the two ends of the same pipe material, and after confirmation, the carrying work is carried out. According to the length of the pipe material, when the pipe material is shorter, the strong light lamp 17 is turned on, and the carrying personnel at one end of the pipe material only need to clamp the device on one end of the pipe material. The strong light can effectively pass through the pipe material, and the carrying personnel at the other end can quickly identify the pipe material to be carried. When the pipe material to be carried is longer, the effect of the strong light lamp 17 is reduced, the strong light lamp 17 is turned off, and the laser lamp 18 is turned on. Due to the Tyndall effect, the carrying personnel at the other end of the pipe material can still quickly identify the pipe material to be carried, and the carrying efficiency is greatly improved.
