[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0026] like Figure 1-Figure 3 As shown, in one embodiment, a drive half shaft disassembly tool specifically includes:

[0027] The main rod 1 is a straight rod made of metal. When the driving half shaft is removed by transmitting force through the main rod 1, the strength of the main rod 1 can enable normal use and reduce the risk of breakage. A handle 2 is preferably welded on one end of the main rod 1, and a disassembly plate 3 is detachably connected to the other end of the main rod 1. An opening 4 is provided on the disassembly plate 3, and the opening 4 can be inserted into the outside of the driving half shaft. A counterweight 5 is slidably arranged on the main rod 1.

[0028] When in use, after the dismantling plate 3 is extended to the position of the driving half-shaft, the opening 4 of the dismantling plate 3 is inserted into the driving half-shaft. The operator holds the handle 2 with one hand and slides the counterweight 5 on the main rod 1 with the other hand. Since the counterweight 5 has a certain weight, after the counterweight 5 hits the end face of the handle 2 by inertia, it can drive the dismantling plate 3 to dismantle the driving half-shaft. The overall disassembly is more convenient and there is no need to remove the surrounding accessories, so it is faster to use.

[0029] Furthermore, with regard to the connection method between the dismantling disc 3 and the main rod 1, in the present embodiment, a threaded hole is provided on the chuck, and the end of the main rod 1 is a threaded structure, and the two can be connected to the main rod 1 through a threaded device, so that when in use, the dismantling disc 3 can be firmly connected to the main rod 1, and a reinforcing sleeve 6 is provided on the surface of the dismantling disc 3, and a threaded structure is also provided on the inner wall of the reinforcing sleeve 6, and a plurality of reinforcing ribs 7 are provided on the outside of the reinforcing sleeve 6 and connected to the surface of the dismantling disc 3. The strength of the connection between the dismantling disc 3 and the main trunk can be reinforced by the arrangement of the reinforcing sleeve 6 and the reinforcing ribs 7, so as to improve the service life of the entire dismantling tool.

[0030] In other feasible embodiments, the dismantling plate 3 and the main rod 1 may be a welded structure, and a reinforcement sleeve may be welded again at the welding position (not shown in the figure) to enhance the connection strength between the main rod 1 and the dismantling plate 3.

[0031] Furthermore, the main rod 1 is installed perpendicular to the surface of the dismantling plate 3, so when the main rod 1 moves to one end, it can drive the dismantling plate 3 to remove the driving half shaft.

[0032] Furthermore, a limit block 8 is provided on the main rod 1. The limit block 8 is provided at one end of the counterweight 5 away from the handle 2. The limit block 8 and the handle 2 respectively limit the two ends of the counterweight 5. The limit block 8 can prevent the counterweight 5 from moving to the side close to the dismantling plate 3, causing collision to the dismantling plate 3, and affecting the connection strength and service life between the dismantling plate 3 and the main rod 1. At the same time, a buffer pad 9 is provided on the end surface of the limit block 8 and the handle 2 relative to the counterweight 5. The buffer pad 9 can prevent the counterweight 5 from directly colliding with the limit block 8 and the handle 2, thereby reducing the service life problem. As for the material of the handle 2, the part close to the counterweight 5 is metal, and the rest can be made of high-strength plastic. While being able to meet the use requirements, it can also reduce the weight of the entire tool, making it more comfortable to use.

[0033] For further information, see Figure 3 An annular rod 10 is arranged around the outside of the counterweight 5, and the annular rod 10 is connected to the counterweight 5 by a fixing rod, and there is a gap between the annular rod 10 and the counterweight 5. By providing the annular rod 10, the operator can use the counterweight 5 more conveniently and quickly. An anti-skid layer is arranged on the surface of the annular rod 10, and the risk of slipping during use can be reduced by providing the anti-skid layer.

[0034] As for the counterweight block 5, in the present embodiment, the counterweight block 5 is a counterweight spring block, and the counterweight spring block specifically has a plurality of spring parts arranged at one end thereof. When the spring parts come into contact with the handle 2, the hard damage of the handle 2 caused by the counterweight block 5 can be reduced through the spring parts.

[0035] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
