[0019] By installing a locking groove on one side of the transmission arm, the locking groove and locking block form a locking structure. The locking blocks at both ends of the connecting piece can lock into the locking groove of the transmission arm. The left and right transmission arms are connected by the connecting piece. Conventional hand pullers use shaft connections, which greatly increases costs. This hand puller uses connecting pieces for connection, which requires less material and effectively reduces costs, thereby achieving the goal of reducing the cost of the tensioning device.

[0020] By installing an unlocking fingerprint sleeve on the top of the unlocking component, the unlocking fingerprint sleeve and the unlocking component form a locking structure. The reset spring is elastic, allowing the unlocking component to be reset after rotation. At the same time, the unlocking fingerprint sleeve was originally a dip-molded part, but the unlocking fingerprint sleeve of this hand puller is a separate type, which is directly inserted and installed, greatly increasing versatility and modifiability, while speeding up the processing efficiency and making production smoother. This achieves the purpose of making the tensioning device easier to enhance versatility. Attached Figure Description

The unlocking component 902 and the unlocking fingerprint sleeve 901 form a locking structure. The reset spring 903 is installed at the bottom of the unlocking component 902.

[0032] See attached document Figures 1-2 and attached Figure 5 As shown, the fingerprint unlocking sleeve 901 and the unlocking component 902 form a snap-fit ​​structure. The reset spring 903 is elastic, allowing the unlocking component 902 to be reset after rotation. Originally, the fingerprint unlocking sleeve 901 was a dip-molded part, but this hand puller's fingerprint unlocking sleeve 901 is a separate type, directly inserted for installation, which greatly increases versatility and modifiability, while also speeding up processing efficiency and making production smoother.

[0033] A second webbing 4 is installed on one side of the transmission arm 10, and a webbing shaft 3 is installed on one side of the transmission arm 10.

The long webbing is telescopic, while the short webbing is of a fixed length. This hand puller can use two long webbings. By changing the way the webbing is threaded, the webbing or the hand puller can be adjusted to a suitable position when loosened. This avoids the awkward position that sometimes occurs with conventional hand pullers due to the fixed length of the short webbing, which affects the subsequent tightening operation. After confirming the initial position, as... Figure 3 As shown, the handle of the hand puller is repeatedly pulled in the direction of the arrow, causing the axis 201 to move in the direction of the arrow, thereby achieving the effect of simultaneously collecting the long strips on both sides of the case.

[0036] A first webbing 1 is installed on one side of the rotating structure 2. The first webbing 1 is a long webbing, and the second webbing 4 can be a long webbing or a short webbing. It can be a combination of a long webbing and a short webbing, or it can be a combination of two long webbings.
