[0026] The specific implementation of the utility model is further described below in combination with the drawings and examples. The following examples are only used to more clearly illustrate the technical scheme of the utility model, and cannot limit the protection scope of the utility model. Examples

[0027] A belt repairing tool includes a shell 10, two groups of slide rails 11 are arranged in parallel inside the shell 10, the shell is further provided with a slide groove 12, the clamp 20 is slidably connected to the same side of the shell 10 through the slide groove 12, the clamp 20 is provided with a sliding block 21 matched with the slide rail, the sliding block 21 is provided with a rack 22, the gear 23 engaged with the rack 22 is further rotatably connected between the two groups of slide rails 11, and the first rotating handle 13 is fixedly connected to the gear 23 along the axial direction of the gear 23 and penetrates through the shell 10.

[0028] The clamp 20 includes a first clamping part 24 and a second clamping part 25, the first clamping part 24 is fixedly provided with an adjusting cylinder 26, the adjusting cylinder 26 is axially provided with a guide groove 261, the second clamping part 25 reciprocates along the guide groove 261, the clamping bolt 262 is arranged in the adjusting cylinder 26, the clamping bolt 262 is in smooth rotation connection with the adjusting cylinder 26, and the clamping bolt 262 is in threaded connection with the second clamping part 25.

[0029] The first clamping part 24 is provided with a ring-shaped blade 27, the second clamping part 25 is provided with a blade groove 271 matched with the ring-shaped blade 27, the ring-shaped blade 27 is fixedly provided with a column 272, the side of the column 272 is provided with a thread, the first clamping part 24 is connected with the column 272 through the thread, and the end of the column 272 away from the blade is further provided with a second rotating handle 28. The first clamping part 24 and the second clamping part 25 are matched in concave-convex, and the lower surface of the first clamping part 24 and the upper surface of the second clamping part 25 are provided with frosted surfaces.

[0030] The first rotating handle 13 and the shell 10 are provided with a locking mechanism 30, the first rotating handle 13 is a cylinder, the outer side of the cylinder is provided with a gear 23, the inner wall of the cylinder is provided with a ratchet wheel 31, the side of the shell 10 away from the first rotating handle 13 is provided with a locking rod 32, the shell 10 is provided with an opening matched with the locking rod 32, and the locking rod 32 is provided with a pawl 33 matched with the ratchet wheel 31 in the shell 10. The opening and the locking rod 32 are provided with two groups of parallel structures, the two groups of locking rods are guide rods, and the two groups of locking rods are prevented from rotating. On the outer side of the shell 10, the locking rod is further provided with a ring groove 34 along the radial direction, the shell 10 is rotationally connected with a buckle 35 matched with the ring groove 34. After the locking rod 32 is moved upward to make the pawl 33 disengage from the meshed ratchet wheel 31, the buckle 35 is rotated to be buckled with the ring groove 34 to limit the locking rod 32.

[0031] The shell is inlaid with a scale 14 along the moving direction of the slide rail 11, and the adjusting cylinder 26 is fixedly provided with a number display piece 263. The shell 10 is detachably connected with a storage bag 15, the storage bag 15 is opened and closed through a zipper, and the inside is equipped with auxiliary props such as glue and adhesive tape.

[0032] The belt to be repaired is placed between the first clamping part 24 and the second clamping part 25 of the clamp 20. The second clamping part 25 is reciprocated along the guide groove 261 by adjusting the adjusting cylinder 26, so that the distance between the first clamping part 24 and the second clamping part 25 is adjusted. When the appropriate position is reached, the clamping bolt 262 is tightened to tightly clamp the first clamping part 24 and the second clamping part 25. By rotating the first rotating handle 13, the gear 23 is driven to rotate. Since the gear 23 is meshed with the rack 22, the sliding block 21 will move along the slide rail 11. In this way, the clamp 20 can move towards each other along the slide groove 12, so as to adjust the tension of the belt and prevent the problem that the repair is poor due to the change of the tension of the belt. When the shape of the small hole on the surface of the belt is irregular and difficult to repair, the ring-shaped blade 27 can be lowered along the thread of the column 272 by rotating the second rotating handle 28 to cut off the irregular edge of the small hole, and the rotation of the column is avoided after rising to affect the action of the clamp.

[0033] In the repairing process, the first rotating handle 13 can be locked on the shell 10 by the locking mechanism 30 to prevent it from slipping. The specific operation is: when the first rotating handle needs to be rotated, the locking rod is pushed inward to the shell 10, so that the pawl 33 is disengaged from the meshing ratchet 31, and then the buckle 35 is rotated to be buckled in the ring groove 34 to limit the locking rod 32, at this time, it is in the unlocked state, and the gear 23 rotates the first rotating handle 13. When the belt tension is adjusted to the appropriate degree, the buckle 35 is unlocked to limit the ring groove 34, the pawl 33 is engaged with the gear by pulling or relying on the self-weight of the pawl 33 and the locking rod 32, and the locking state is realized. The scale 14 is inlaid on the outside of the shell in the moving direction of the slide rail 11, which is used to indicate the position of the clamp 20, and the indicating disc 263 is fixedly arranged on the adjusting cylinder 26, which is used to display the rotation angle of the adjusting cylinder 26. These designs help the user to more accurately observe the adjustment accuracy and control the repairing process. The shell 10 is detachably connected with the storage bag 15, which is used to store glue, adhesive tape and other auxiliary props. In this way, the whole tooling can be more portable, and the user can conveniently perform the repairing operation on the spot.

[0034] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be regarded as the protection scope of the present application.
