[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] A combined wear-resistant thread comber comprises a mounting plate 1, a first thread comber 2 being provided on the front of the mounting plate 1, a second thread comber 3 being provided on the back of the mounting plate 1, a first mounting block 4 being symmetrically provided on the back of the first thread comber 2, a second mounting block 5 being symmetrically provided on the front of the second thread comber 3, fixing holes 6 being provided on the left and right sides of the first mounting block 4 and the second mounting block 5, fixing grooves 7 being symmetrically provided on the front and back of the mounting plate 1, a first placement groove 8 being provided on the front side of the base surface of the mounting plate 1, a second placement groove 9 being provided on the back side of the base surface of the mounting plate 1, and fixing components 10 being provided inside the first placement groove 8 and the second placement groove 9;

[0025] In this embodiment, please refer to Figure 3The fixing assembly 10 includes a fixing seat 1001, a first gear 1002 is rotatably provided on the upper side of the fixing seat 1001, a second gear 1003 is rotatably provided on the left side of the fixing seat 1001, a third gear 1004 is rotatably provided on the right side of the fixing seat 1001, an adjusting button 1005 is provided on the base surface of the fixing seat 1001, a first threaded rod 1006 is rotatably provided on the left side of the fixing seat 1001, a second threaded rod 1007 is rotatably provided on the right side of the fixing seat 1001, the outer walls of the first threaded rod 1006 and the second threaded rod 1007 are both threadedly provided with adjusting sleeves 1008, and the outer ends of the adjusting sleeves 1008 are both provided with fixing rods 1009.

[0026] Among them, the first mounting block 4 and the second mounting block 5 are respectively adapted to the fixing groove 7, so that the first mounting block 4 and the second mounting block 5 can enter the interior of the fixing groove 7, the fixing rod 1009 is adapted to the fixing hole 6, so that the fixing rod 1009 can enter the interior of the fixing hole 6, the front and rear sides of the adjusting sleeve 1008 are symmetrically provided with limiting rods, and the interiors of the first placement groove 8 and the second placement groove 9 are provided with limiting grooves corresponding to the limiting rods, the bottom of the fixing seat 1001 is respectively fixedly connected to the first placement groove 8 and the second placement groove 9, the second gear 1003 and the third gear 1004 are both meshed with the first gear 1002, the right end of the first threaded rod 1006 is connected to the second gear 1003, and the second threaded rod 1 The left end of 007 is connected to the third gear 1004. By arranging a fixing component 10 on the combined wear-resistant thread combing cutter, rotating the adjusting button 1005 can drive the first gear 1002 to rotate, and with the cooperation of the second gear 1003 and the third gear 1004, respectively drive the first threaded rod 1006 and the second threaded rod 1007 to rotate, thereby driving the fixing rod 1009 to move with the cooperation of the adjusting sleeve 1008. When the fixing rod 1009 is moved out from the inside of the fixing hole 6, the first mounting block 4 and the second mounting block 5 can be moved out from the inside of the fixing groove 7, so that the first thread combing cutter 2 and the second thread combing cutter 3 can be replaced, which is more convenient during replacement. The overall device has a simple structure, is easy to operate and has higher practicality.

[0027] The working process of the utility model is as follows: when using the combined wear-resistant thread combing tool, when the first thread combing tool 2 and the second thread combing tool 3 need to be replaced, the adjusting button 1005 is first turned. When the adjusting button 1005 is turned, the first gear 1002 is driven to rotate. Since the second gear 1003 and the third gear 1004 are both connected to the first gear 1002 in a meshing connection, when the first gear 1002 rotates, the second gear 1003 and the third gear 1004 are driven to rotate at the same time. When the second gear 1003 and the third gear 1004 rotate, they respectively drive the first threaded rod 1006 and the second threaded rod 1007. The threaded rod 1007 rotates, and since the adjusting sleeve 1008 is threadedly connected to the first threaded rod 1006 and the second threaded rod 1007 respectively, and is limited by the limiting rod and the limiting groove, the adjusting sleeve 1008 is driven to move when the first threaded rod 1006 and the second threaded rod 1007 rotate, and the fixing rod 1009 is driven to move inward by the adjusting sleeve 1008. When the fixing rod 1009 moves to the outside of the fixing hole 6, the first mounting block 4 and the second mounting block 5 are pulled outward respectively to disassemble the first thread comb 2 and the second thread comb 3, thereby facilitating their replacement.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
