The utility model has the advantages that: through set up the handle screw rod on the sliding ring, utilize the rotation of handle screw rod to lock the sliding ring or remove the locking to the sliding ring, it is more convenient during the use, the function is stronger.

Description of the drawings:

fig. 1 is a schematic diagram of a traction snare.

The figures are numbered: 1. core bar, 2, sliding ring, 3, handle screw, 4, electrode, 5, protection cover of preventing electrocution.

The specific implementation mode is as follows:

the present invention will be described in detail with reference to the accompanying drawings.

As shown in the attached figure 1, the snare for traction comprises a sliding ring 2, a core bar 1 and a handle screw rod 3, wherein the sliding ring 2 is slidably sleeved on the core bar 1, the sliding ring 2 is provided with a screw hole, and the handle screw rod 3 is arranged in the screw hole of the sliding ring 2; when the handle screw 3 abuts against the rod wall of the core rod 1, the slip ring 2 is fixed on the core rod 1.

Through set up handle screw rod 3 on sliding ring 2, utilize handle screw rod 3's rotation to lock sliding ring 2 or remove the locking to sliding ring 2, it is more convenient during the use, the function is stronger.

As shown in fig. 1, the handle screw 3 is perpendicular to the core rod 1.

The handle is perpendicular to the core rod 1 in order to reduce wear on the core rod 1.

As shown in fig. 1, the slip ring 2 is provided with an electrode 4. The electrode 4 can be sleeved with an electric shock protection sleeve 5.

As shown in fig. 1, the electrode 4 is integrally formed with the slip ring 2.

As shown in fig. 1, the electrodes 4 and the handle screw 3 are respectively located on two sides of the core bar 1.

The electrode 4 and the handle screw 3 are respectively positioned at two sides of the core rod 1, so that the electrode 4 and the handle screw 3 are prevented from interfering with each other, and more stability in use is ensured.

As shown in fig. 1, the electrode 4 is aligned with the handle screw 3.

The electrode 4 and the handle screw rod 3 are on the same straight line, so that the center of gravity of the whole sliding block is positioned at the core rod 1, the sliding block can be ensured to be more stable during sliding, and the phenomenon of blocking is reduced.

As shown in fig. 1, the slip ring 2 is perpendicular to the core rod 1.

The slip ring 2 is perpendicular to the core rod 1, so that the resistance of the slip ring 2 during sliding can be reduced. When the slip ring 2 is perpendicular to the core rod 1, the electrode 4 and the handle screw 3 are respectively positioned at two sides of the core rod 1, and the electrode 4 and the handle screw 3 are in a straight line, the gravity center of the whole snare is ensured to be on the core rod 1, the stability of the whole snare is ensured to be stronger, and the operation of an operator is facilitated.

As shown in fig. 1, the slip ring 2 is provided with two circular holes.
