[0040] The traction mechanism 3 includes a connecting rod 31 and a traction assembly 32 which are arranged at an angle to each other, and one end of the connecting rod 31 is slidably connected with the telescopic assembly 22;

[0041] The traction assembly 32 includes a plurality of traction ropes 321, and a front-rear adjustment assembly 5 is provided between the traction ropes 321 and the connecting rod 31, and the front-rear adjustment assembly 5 is used to adjust the distance between the traction ropes 321 and the supporting mechanism 2;

[0042] The front-rear adjustment component 5 is provided with a traction rope connection structure 6 connected to both ends of the traction rope 321, and the traction rope connection structure 6 is used to adjust the length of the "V"-shaped free drop formed by the traction rope 321 under the action of its gravity.

[0043] In this embodiment, the traction height can be adjusted by the telescopic component 22, the traction position can be adjusted by the front and rear adjustment component 5, the length of the traction rope 321 in a "V"-shaped free hanging state can be adjusted by the traction rope connection structure 6, and the traction angle can be adjusted by the angle adjustment component 4;

[0045] Through the above structure, the required height, angle and position of the traction hand can be adjusted according to actual conditions to achieve the best traction state; the traction process is completed automatically. In addition, due to the setting of the traction rope 321, the hand can be moved and adjusted appropriately and flexibly, and the traction is comfortable and effective.

[0046] Further, such as Figure 1 , 2 As shown, the angle adjustment assembly 4 includes a ball head 41 connected to the telescopic assembly 22, a connecting portion 42 connected to the support rod 21, and a first locking sleeve 43;

When locked, it limits the freedom of sliding of the ball head 41 relative to the spherical surface 421, thereby limiting the freedom of angle adjustment of the telescopic component 22 relative to the support rod 21, thereby achieving adjustment and locking of the traction angle.

[0049] In this embodiment, during installation, the telescopic component 22 is connected to the spherical surface 421 of the connecting portion 42 through the ball head 41, and then the end of the telescopic component 22 away from the ball head 41 passes through the avoidance hole 431 of the first locking sleeve 43.

[0058] The limiting assembly 7 includes a locking rod 71 threadedly connected to the connecting hole 20 , and the locking rod 71 can be separated from or inserted into the locking hole 10 .

[0059] In this embodiment, in the above structure, when the connecting hole 20 is coaxial with any of the locking holes 10, the locking rod 71 can be inserted into or disengaged from the locking hole 10 by twisting it forward or reversely, thereby adjusting the height position of the connecting rod 31 in the connecting section 222b. The adjustment process is convenient and reliable, and the locking is firm.

[0060] Further, such as Figure 2 , 3 As shown, in order to facilitate twisting and pulling the lock rod 71 , a pull ring 72 is provided at the outer end of the lock rod 71 .

The traction rope 321 is connected to the hanging plate 53 through the traction rope connection structure 6.

[0063] In this embodiment, the above structure realizes the change of the position of the traction rope 321 by connecting the hook member 52 with the hanging grooves 51a at different positions on the extension section 51, thereby realizing the adjustment of the traction position, and the adjustment process is simple and convenient.

[0064] In this embodiment, the connection method between the hook and the hanging groove 51a is, firstly, convenient for arbitrary adjustment, and secondly ensures that the connection position is not easily detached, so that the hanging plate 53, the hook member 52 and the traction rope 321 as a whole can swing flexibly with the movement of the hand being towed, and the relatively fixed connection structure effectively improves the traction comfort.
