[0017] The first embodiment of the present application is:

[0018] See also Figure 1 , Figure 1 It is a cross-sectional view of a thread milling tool according to the first embodiment of the utility model.

[0019] The utility model provides a thread milling tool, including a support plate 101, a fixing mechanism 102, a fastening threaded rod 103 and a support mechanism 104, wherein the support mechanism 104 includes a driving assembly 105, two transmission assemblies 106 and two rotating rods 107, wherein the driving assembly 105 includes a motor 108 and a driving gear 109, and the transmission assembly 106 includes a rotating shaft 110 and a driven gear 111. The above-mentioned solution solves the problem of low material fixing efficiency of the existing milling tool, and it can be understood that the above-mentioned solution can be used in the scenario of twisting the fastening threaded rod 103.

[0020] According to this specific embodiment, the fixing mechanism 102 is arranged on the top of the support plate 101, the fastening threaded rod 103 is threadedly connected to the support plate 101 and is located on the inner wall of the support plate 101, the driving assembly 105 is arranged at the bottom of the support plate 101, the two transmission assemblies 106 are respectively arranged on both sides of the driving assembly 105, and the two rotating rods 107 are respectively arranged on one side of the two transmission assemblies 106. Threaded holes are symmetrically provided on both sides of the support plate 101, and limited sliding grooves are symmetrically provided on both ends of the support plate 101. A fastening threaded rod 103 is rotatably inserted into the internal thread of the threaded hole, and a fixing mechanism 102 is slidably clamped inside the limiting sliding groove. A sliding card is installed at the bottom end of the fixing mechanism 102, and fixing grooves are symmetrically provided on both sides of the sliding card. A connecting plate is installed on the upper part of one end of the sliding card, and a fixing plate is connected to the front end of the connecting plate. A placement groove is provided in the middle of the front end surface of the fixing plate, and threaded adjustment rods are threadedly rotated and inserted through both sides and the middle of the fixing plate, and the ends of the threaded adjustment rods are connected to adjusting hand wheels. The support plate 101 is used to place materials, and the fixing mechanism 102 is fixed to the support plate 101 by the fastening threaded rod 103 to fix the materials. When the fastening threaded rod 103 is screwed, the driving assembly 105 drives the two transmission assemblies 106 to drive the rotating rod 107 to rotate, so that the two rotating rods 107 are rotated out from the bottom of the support plate 101 and contact the placement surface, and lift the support plate 101 from the placement surface. The closer the two rotating rods 107 are, the higher the height of the support plate 101 from the placement surface is, until the height from the placement surface is greater than the required height for screwing the fastening threaded rod 103, thereby solving the problem of low efficiency of fixing materials with existing milling tools.

[0021] The motor 108 is fixedly connected to the support plate 101 and is located on the inner wall of the support plate 101, and the driving gear 109 is fixedly connected to the output end of the motor 108. The motor 108 drives the driving gear 109 to rotate.

[0022] Secondly, the rotating shaft 110 is rotatably connected to the support plate 101, and is fixedly connected to the rotating rod 107, and is located on the inner wall of the support plate 101. The driven gear 111 is fixedly connected to the rotating shaft 110, and is meshed with the driving gear 109. The driving gear 109 drives the driven gear 111 to drive the rotating shaft 110 to rotate, and the rotating shaft 110 drives the rotating rod 107 to rotate out from the bottom of the support plate 101.

[0023] When the fastening threaded rod 103 is screwed, the motor 108 drives the driving gear 109 to rotate, and the driving gear 109 drives the driven gear 111 to drive the rotating shaft 110 to rotate. The rotating shaft 110 drives the rotating rod 107 to rotate out from the bottom of the support plate 101 and contact the placement surface, and lift the support plate 101 from the placement surface. The closer the two rotating rods 107 are, the higher the height of the support plate 101 from the placement surface is, until the height from the placement surface is greater than the required height for screwing the fastening threaded rod 103, thereby solving the problem of low efficiency of existing milling tools in fixing materials.

[0024] The second embodiment of the present application is:

The roller 202 is rotatably connected to the expansion plate 201 and is located on the inner side wall of the expansion plate 201.

[0028] The expansion plate 201 connects the roller 202 with the rotating rod 107, and the rotating rod 107 rolls on the placement surface after contacting the placement surface through the roller 202, thereby reducing the friction between the placement surface and the roller 202. The roller 202 is provided with a brake pad, and when the roller 202 needs to be braked, the roller 202 can be braked by the brake pad. There are multiple rollers 202, and the number can be determined according to the width of the support plate 101.
