Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 2 The locking mechanism 2 in this embodiment includes a mounting plate 204 fixed to the left side of the driving mechanism 6. The internal thread of the mounting plate 204 is connected to a threaded rod 202. The threaded rod 202 rotates to match the threaded hole to move the locking plate 203 toward the left side plate 4. Both ends of the threaded rod 202 pass through and extend to the outside of the mounting plate 204. The right end of the threaded rod 202 is fixed with a locking plate 203. After the locking plate 203 abuts against the positioning component of the driving mechanism 6, the roller body 3 will be locked. The left end of the threaded rod 202 is fixed with a handle 201, and the threaded rod 202 is rotated by the handle 201.

[0024] A threaded hole is provided inside the mounting plate 204 , and the threaded rod 202 is threadedly connected inside the threaded hole. The threaded rod 202 can move linearly left and right inside the threaded hole.

[0025] By rotating the threaded rod 202 , the locking plate 203 can lock the roller body 3 , thereby quickly braking the roller body 3 .

[0026] The locking mechanism 2 can conveniently lock the pay-off roller 3. By rotating the handle 201 and the threaded rod 202, the locking plate 203 can be brought into contact with the side plate 4, thereby locking the roller 3 to prevent the roller 3 from paying out too long due to inertia.

[0027] See also Figure 3 The abutment mechanism 5 in this embodiment includes a screw rod 501 fixed on the upper surface of the bottom plate 1, and the outer side of the screw rod 501 is threadedly connected with a threaded sleeve 502. By rotating the threaded sleeve 502, the threaded sleeve 502 can move upward on the screw rod 501. A connecting seat 505 is movably connected between the two side plates 4. As the threaded sleeve 502 moves, the connecting seat 505 can be lifted up to make the abutment roller 504 move toward the roller body 3. A connecting rod 503 is fixed inside the connecting seat 505, and the connecting rod 503 is rotatably connected to the inside of the connecting rod 503. After the abutment roller 504 abuts against the cable, it can prevent the roller body 3 from becoming loose in the direction. The connecting seat 505 is placed on the top of the threaded sleeve 502. Under the action of the threaded sleeve 502, the moving distance of the abutment roller 504 can be adjusted at will to adapt to the thickness of different cables. The top of the screw rod 501 penetrates and extends to the inside of the connecting seat 505.

[0028] A through hole is provided inside the connecting seat 505 for the screw 501 to pass through. The connecting seat 505 is a U-shaped seat. The abutting roller 504 moves linearly up and down under the roller body 3. The length of the connecting seat 505 is equal to the length of the roller body 3. A mounting hole is provided inside the abutting roller 504. The connecting rod 503 is rotatably connected to the inside of the mounting hole through a bearing.

[0029] By rotating the threaded sleeve 502, the distance between the abutting roller 504 and the roller body 3 can be adjusted to prevent the cable from becoming loose when paying out the cable.

[0030] The abutment mechanism 5 can prevent the cable from becoming loose. Under the action of the rotating threaded sleeve 502 and the screw 501, the abutment roller 504 can tighten and limit the cable wound on the roller body 3, and the movable abutment roller 504 can also adapt to the thickness of the cable.

[0031] The working principle of the above embodiment is:

[0032] (1) When the roller body 3 needs to be braked quickly, the threaded rod 202 can be rotated by the handle 201. The threaded rod 202 rotates to match the threaded hole to move the locking plate 203 toward the left side plate 4 and abut against the positioning component of the drive mechanism 6. After the positioning component is locked by the locking plate 203, the roller body 3 is also locked, thereby preventing the rotating roller body 3 from releasing too long a cable due to inertia.

[0033] (2) When the roller body 3 is releasing the wire, in order to prevent the cable from becoming loose, the contact roller 504 can be made to contact the cable on the roller body 3. During the contact, the threaded sleeve 502 can be rotated to move the threaded sleeve 502 upward on the screw 501. As the threaded sleeve 502 moves, the connecting seat 505 can be lifted up to move the contact roller 504 toward the roller body 3. After the contact roller 504 contacts the cable, the roller body 3 can be prevented from becoming loose in the direction. Under the action of the threaded sleeve 502, the moving distance of the contact roller 504 can be adjusted at will to adapt to the thickness of cables of different sizes, thereby improving the practicability of the device.
